The approach is divided into six steps,as follows: -Analyze and describe operational characteristics,construction phasing,management objectives,and facilities'design stan- dards related to the Susitna Hydroelectric Project; -Determine locations and levels of existing recreation and fore- cast impacts of the project on existing recreation; -Estimate existing and future recreation use patterns and demand; -Evaluate the intrinsic physical recreation opportunities and constraints of the land; -Develop the recreation use plan,develop conceptual designs of proposed sites,determine development levels and estimated user levels;and -Describe mechanisms for plan implementation,construction and maintenance (see Figure E.7.1). Section 1.4 describes the proposed Sustina Hydroelectric Project. Section 2 describes the existing recreation within the project's statewide and regional settings.Included are descriptions of facilities,activities,and the relationship of the project to existing recreation use patterns.Section 3 describes the impacts of the Watana and Devil Canyon project features,access routes,and the transmission lines on recreation and the proj- ect l s future demand for area recreation with and without the Susitna project. Sect ion 4 descri bes the factors i nfl uenc i ng the recreation use plan.These factors include Power Authority,agency,and Native corporation management objectives,design standards,and Alaska Power Authority's financial obligations and responsibilities. Section 5 is the recreation use plan and includes an evaluation of the study area's intrinsic recreation potential,a recreation opportunity evaluation,proposed development levels,and recrea- tion sites.This plan constitutes mitigations for impacts ~I -. ~, - - - E-7-2 - ~, - - 1.3 -Study Approach and Methodology identified in Section 3.Section 6 describes the Recreation Use Plan implementation,phasing,monitoring,and future additions. Section 7 describes the costs associated with construction opera- tions and maintenance of proposed facilities. Every effort has been made to utilize the results of past studies and agency plans both of the Susitna Project itself and those of a more general nature.Particular emphasis has been given to the Susitna Hydroelectric Project Subtask 7.08 Report,(TES 1982b). Use was made both of that published report ~nd the field data and background files utilized in its preparation.Additional results of a survey conducted as part of that effort have also been util- ized in the formulation of this Recreation Plan. 1.3.2 -Methodology Figure E.7.1 illustrates the study methodology employed in devel- opment of the recreation plan for the Susitna Hydroelectric Proj ect. Step 1 determined study objectives and developed a detailed work plan.This activity included review of all relevant agency docu- ments and interviews with key agency personnel identified by the Power Authority.Objectives of each agency were determined as they relate to this ~recreation plan and included in Section 4 of this document.When combined with FERC Order 184,they consti- tute the objectives of this study as found in Section 1.1 of this report. Step 2 included the parallel activities of an inventory of exist- ing recreation facilities and plans and an estimate of future recreation demand with and without the project.An existing methodology for estimating future recreation demand was used as a basis for a project-related recreation demand methodology.In addition,four other approache's were util ized as a general check of results. Step 3 consisted of an onsite inventory of existing recreation potential.This activity involved study of existing relevant project documents and previous studies,and extensive onsite investigations.Step 4 evaluated recreation opportunity based on information from Step 2 and defined the qualitative and quantita- tive aspects of site recreation potentials. Step 5 is a further refinement of the opportunity evaluation and constitutes recommended recreation plans and alternatives for the project. E-7-3 1.4 -Project Description and Interpretation Step 6 developed an implementation plan,including plan phasing, demand monitoring,and estimated costs. A detailed discussion of specific methodology employed is found in the introduction to individual report sections. 1.4 -Project Description and Interpretation In order to develop a recreation plan related to hydroelectric develop- ment,it is first necessary to understand the project and its operation as it relates to recreation.The Susitna Hydroelectric Project is com- prised of two major dams with storage reservoirs,penstocks and under- ground powerhouse,transmission 1 ines,a rail road,and roads for con- struction and operation;two temporary single-status construction camps;two temporary married-status construction camps;a permanent village;and a landing strip.The project transmission lines connect to the Anchorage-Fai rbanks Intertie,a separate project planned for construction beginning late 1982 and scheduled for operation in Septem- ber 1984.The Intertie is not considered in this recreation plan. 1.4.1 -Construction (a)Watana Dam and Reservoir The Watana schedule anticipates issue of the FERC license by December 31,1984 (see Exhibit C),and is predicated on having four units on 1 ine by the end of 1993 and an addi- tional two units by July 1994 in order to meet forecasted load demand.Construction of an approximately 41.6-mile (61.7-km)access road commencing atl~ile 110 of the Denali Highway and an airstrip near the site are planned to begin in January 1985 (see Figure E.7.2).Labor,equipment,and materials will be mobilized beginning in 1985.A temporary construction camp (single-status)ultimately housing 3480 workers and a construction village ultimately housing 350 families (1120 population)will be developed.Construction labor for the 885-foot (2170-m)high,4100-foot (l250-m) crest length embankment dam and the 1020-MW powerhouse will peak in 1990 with about 3500 workers. Construction of the two 33.6-mile (56-km)long 345-kV trans- mission lines will begin in 1989 and extend through 1992. They will be constructed primarily in the winter months. Impoundment of the reservoir,being 38,000 (14,200 ha)acres and 54 river miles (90 river krn)long and with a gross stor- age capacity of 9,470,000 acre-feet,will begin in June 1991 and be completed in late 1993.As development nears comple- tion,a permanent town near the construction camps intended to house a permanent work force of 125 plus dependents will E-7-4 - ~ , - - - - - ~I 1.4 -Project Description and Interpretation be constructed,and the original camps will be relocated to the Devil Canyon site. - (b)Devil Canyon Dam and Reservoir Devil Canyon construction is planned to begin as Watana approaches completion.Between early 1992 and mid-1994,a 37-mile (62-km)access road will be developed between Watana and Devil Canyon,including construction of a high-level bridge across Devil Canyon (see Figure E.7.2).A railroad will be constructed from Gold Creek to Devil Canyon.The Alaska Power Authority will defer decision on the publ ic use of the access route from the Denali Highway until that time. However,for the purpose of this recreation plan it has been assumed that this road,no longer being heavily used for construction,will be opened to public access.Most con- struction materials will be brought to Devil Canyon on a new 12.2-mile (20-km)railroad from Gold Creek.A single-status camp for 1780 workers and a married-status village for 170 workers (550 people)will be constructed,utilizing struc- tures brought from Watana to the extent possible.One of the 345-kV Watana transmi ssi on 1 i nes wi 11 be tapped for con- struct i on power.Const ruct i on work force for the 645-foot (197-m)high,1650-foot (500-m)crest length thin arch con- crete dam and the 600-MW powerhouse will peak at about 1800 workers in 1999 and extend to 2002.Two additional 8.8-mile (14.7-km)long,345-kV transmission lines will be built to connect with the Intertie.An additional parallel 345-kV will be added to the Intertie itsel f.Impoundment of the reservoi r will be 7800 acres (3080 ha)and 32 ri ver mi 1es (53 km)long and with a gross storage capacity of 1,090,000 acre-feet,wi 11 occur over a two-month period in 2001.The project will then be on line in 2002.The construction camp and village will be removed,and both Watana and Devil Canyon will be operated by the same personnel resident at the Watana townsite.It is assumed that the road connecting Watana and Devil Canyon will be opened to the public and the railroad,no longer needed for continuous project use,will potentially be available for public use. ""'" - - 1.4.2 -Operational Characteristics of the Project (a)Watana Dam and Reservoi r The Watana dam and power plant are intended to provide base- load power supply supplementing existing ahd planned thermal and hydroelectric sources for the Railbelt beginning in 1993.Present plans also call for operation of Watana as essentially a baseloaded plant from 1993 to 2002,at whish E-7-5 1.4 -Project Description and Interpretation time it wi 11 be used as a daily peaki ng pl ant for load- following during the high-demand winter months.Watana res- ervoir will have a typical width of 1 mile (1.6 km),w.iden- ing at Watana Creek to a maximum of 5 miles (8 km).Crest elevation of the dam will be 2210 feet (670 m),and water surface elevation during maximum probable flood conditions will be 2202 feet (658 m).Normal maximum operating eleva- tions will be 2185 feet in September with a low of 2080 feet (630 m)in April or May.During breakup and through the most imporant recreation months of June,July,and August water level s will be increasing,reaching a peak in early September.Live storage area will be 3,740,000 acre-feet, and drawdown fl ats may range from a few hundred feet in canyon areas to several square mil es in flatter areas such as Watana Creek (see Figure E.7.4). As indicated in Table E.7.1,the Susitna River exhibits typical flow characteristics of arctic rivers.The table shows existing (pre-project)flows at three locations:Gold Creek,about 16 miles (27 km)below Devil Canyon;'Sunshine, approximately 49 miles (82 km)farther downstream,and Susitna,another 53 miles (89 km)downstream.At Gold Creek,flows approach 6000 cubic feet per second (cfs)in October,the start of the water year.This rapidly de- creases in November,December,January,February and March as the river freezes for the winter.At breakup,flows are over 13,000 cfs in May and peak in June.Average monthly flows gradually decrease in July (24,000 cfs),August (22,000 cfs),and September (13,000 cfs).The effect of the Watana project as currently planned will be both to moderate these wide fluctuations and also to redistribute flows, raising them in the winter,to provide energy in these high energy demand months.Flows wi 11 fl uctuate from about 7700 cfs in April to 37,000 cfs in August,contrasted with 1100 cfs in March to a 90,000 cfs peak flood flow in June under natural conditions.Flows will increase over natural condi- tions in seven months (October through April),and will de- crease in the remaining months.In the important recreation months of June through August,fiows will be decreased from current flows.At Sunshine and Susitna,the same general patterns perta in,although the effects are proportionately much less as additional water sources join the river.The entire upper basin of the Susitna contributes less than 20 percent of the total Susitna discharge into the Cook Inlet. (b)Devil Canyon Dam and Reservoir The Devil Canyon dam and power plant is intended to provide baseload power supply.It wi 11 al so operate as a E-7-6 - -, - - - - r- , - f""" I 1.5 -Implications of Project Design and Operation re-regulating dam for peaking flows from Watana,modulating downstream flows. Devil Canyon Reservoir will have a surface area of 7800 acres (3080 ha),with a length of 32 miles (53 km),con- tained in a narrow canyon generally 0.25 to O.5-mile (0.4 to 0.8-km)wide.It will extend nearly to the toe of l~atana Dam at maximum elevation.Crest elevation of the dam will be 1472 feet (445 m),and water surface elevation during maximum probable flood conditions will be 1466 feet (443 m). Normal maximum operating elevation will be 1455 feet (439 m) most of the year with a low of 1405 feet (424 m)in September during dry years (see Figure E.7.5).Unlike Watana,which will be operated with a September-October high and an Apri l-May low,Devi 1 Canyon wi 11 remai n at its normal elevation from October through July.It will be drawdown in Augu st and ear ly September,be at a mi nimum e 1evat i on of about 1405 feet (424 m)in September,and refill in October. Table E.7.1 also compares pre-and post-project flows show- ing combined Watana and Devil Canyon operations at the three downstream locations.Flows tend to decrease slightly in October,May,June,July,and August compared with the Watana-only operation,and increase slightly in the remain- i ng months. 1.5 -Implications of Project Design and Operation on Recreation Planning The physical character of the ieservoirs themselves and the operational characteristics of the projects have important implications for estab- lishment of the recreation plan concept: The f ast-fl owi ng ri ver and the tumultuous ri ver canyon experi ence which attracts a very small number of.kayaker~and other river run- ners wi 11 be changed to a 1ake experi ence between Vee Canyon and Dev i 1 Canyon; -Both lakes will be cold and silty.Watana in particular will be large enough that wind and chop conditions could constitute potential hazards for small boat recreationists; -The large drawdowns,particularly at Watana,will create mudflats which will be unattractive,difficult to cross,and sources of blow- ing dust and dirt.However,water levels will be relatively high during the summer recreation months; -Where canyon sides are steep,unstable banks will be a greater pro- blem than drawdown.Large bank s'lumps,landslides,and scale,;will be unattractive and potentially dangerous.In either instance, E-7-7 \ \ J I~ ( \ 1.5 -Implications of Project Design and Operation development of boating or shoreline facilities will be extremely dif- ficult,hazardous,and unattractive; -Other lakes and streams in the project area already constitute recre- at i on resources whi ch are far superi or to t he proposed reservoi rs. Road access will greatly increase their use potential,particularly to sports fishermen; -The image of the area will continue to be one of a distant location remote from population centers since the road position causes the dams to be over 5 hours away from both Fairbanks and Anchorage,and hunters and fishermen will continue to reach .the site by airplane; -Whi le there is some opportunity for cross-country ski development, climate,distance and sunlight-shortened days will limit the area to predominantly summer recreation;and -The IIdead-end"nature of the access road will discourage casual "drive-through tourism and sightseeing.Tourists wIll,however,be j attracted to both dams and powerhouse facilities.Therefore,plan- ning should include considerations for public observation of opera- tions and interpretive information.

The ope~~Al aska contain some of the nlOst prist'ine and spectacular scenery and the most sensitive wild lands in the nation.Having the smallest and youngest population living 'in the largest land area of any state,Alaska once seemed an endless frontier.Less than a decade ago Al askans enjoyed virtually un- limited potential for outdoor recreational opportunities.How- ever,as rapid land status changes take place,a reduction of the available public recreation land and opportunities is imminent. The 1971 Alaska Native Claims Settlement Act will transfer 44 million acres of public resource lands to private ownership with- in the next few years.While the conveyance is still in pro- gress,many selected lands include established recreation areas. In addition,the state legislature has directed the Alaska Department of Natural Resources (ADNR)to make state lands avail- able to the public for settlement or agriculture.This ongoing process removes over 20,000 acres (8000 hal a year from publ ic ownershi p. The federal government has set aside another 100 mill ion acres (40 million hal through the Alaska National Interest Lands Con- servation Act (ANILCA),adding 43.6 million acres (17.5 million hal to the National Parks System and 53.7 million acres (21.5 million hal to the National Wildlife Refuge System.Two million acres (800,000 hal we~e placed in Bureau of Land Management (BLM) conservation and recreation areas.Fifty-six million acres (22.4 mill ion hal of the National Park Refuges and National Forest .land were given wilderness protection.These lands represent many beauti ful and sensitive areas of Al aska and expand the area of protected status lands available for outdoor recreation.How- ever,for the most part,these 1 ands are remote and not easi ly accessible by either out-of-state visitors or residents. Al aska State Parks,a division of the ADNR formed in 1971,cur- rently controls 3 million acres (1.2 million hal of state land and water.AONR's policies and programs reflect the recent land status changes.In 1979,ADNR began the Public Interest Land E-7-9 2.1 -St atewi de Sett i ng Identification Project to evaluate surface use values of state lands.This ongoing project identifies the best areas for wild- life habitat,agriculture,recreation,forestry,and settlement and locates the best sites for future state parks and recreation areas.A statewide inventory of public recreation facilities done in 1977 shows that approximately 157 million acres (62.8 million ha)of Alaska's 367.7 million acres (147 million ha)are now classified as public recreation.This inventory is presented in Table E.7.2. 2.1.2 -Regional Setting The Susitna hydroelectric study area lies within the south- central region of Alaska.Recreational planning for this devel- opment must fit within the framework of existing and future regional recreation.Therefore,it is important to understand the regional recreational patterns and trends as well as the state Division of Parks plans. This region extends from the hydrographic divide of the Alaska Range on the north to the Matanuska-Susitna Borough boundary on the west,Kodiak Island on the south and the Alaska/Canada border on the east.It abounds with ocean shorelines,freshwater lakes, free-flowing river systems,massive mountains,large quantities of wildlife,and glaciers the size of states. The di versity of 1andscapes and resources here offer a wi de variety ,of outdoor recreational opportunities,mak-ing it an attractive recreational environment.Figure E.7.3 shows the existing and proposed regional recreational facilities. More than half of Alaskars population lives in south-central Alaska.Anchorage,the largest city,had a 1980 civilian popula- tion of 174,400.The region1s economy is based on support services,commercial fishing,mining,forestry,petroleum,tour- ism,and other private business.Economic trends are primarily toward natural,resource-rel ated development.To uri sm,although rated second in importance for the staters economy,is the fore- most industry supporting the Mat-Su Borough economy. South-central Alaska contains the most highly developed trans- portation system in the state.It is interconnected by paved highways and gravel secondary roads providing good access to much of the area.An extensive airport system ranging from the inter- national level to gravel strips and water bodies permit plane access into much of the remaining land.The Alaska Railroad and ferry systems also service large portions of the region.All of these transportation systems combine with the population concen- trations to make the south-central region1s recreational E-7-10 - - - - - .- '""" - 2.1 -Statewide Setting opportunities the most easily accessible and heavily used in Al aska.See Tabl e E.7.4 for an inventory of statewide recrea- tional facility distribution by regions. 2.1.3 -Existing Facilities The Al aska State Parks System incl udes 82 park uni ts,53 of these are in the south-central region of the state.Table E.7.3 des- cribes the distribution of facilities.throughout the state by region and illustrates this development conc~ntration.Outdoor recreational developments in the south-central region are pri- marily located to serve the two major population centers of Fair- banks and Anchorage and the Railbelt area connecting them. The region's largest and most popular attraction,for both out- of-state tourists and state residents,is the Denali National Park and Preserve.It is located about 220 miles (367 km)north of Anchorage and 125 miles (208 km)south of Fai rbanks on the Parks Highway.It offers visitors views of Mt.McKinley and other major peaks as well as abundant wildlife.The park attracted over 250,000 recreational visitors in 1981.Facilities and services include several lodges,visitor centers,campgrounds as well as trai 1s,gas and bus servi ceo The adjacent Denal i State Park,also entered by the Parks Highway,abuts the Susitna study area.It contains over 324,000 acres 129,600 ha)and offers 37 miles (62 km)of scenic driving,a major roadside camp- ground,trails,picnic grounds,and canoeing and fishing areas. A total of 519,000 visitors used or passed through the park along the Parks Highway in 1981. Seventy miles (117 km)from Anchorage,Nancy Lake State Park has 23,000 acres (9200 ha)and 130 1 akes and ponds.It is heavi ly used by Anchorage residents for water-related recreation as well as hiking and camping (100 units).Chugach State Park,10 miles (l6km)to the east of Anchorage,provides extensive hiking and cross-country skiing opportunities.The park covers 494,000 acres (197,600 ha)and offers major campgrounds (91 units),hik- ing,hunting,boating,and fishing.Lake Lousie,northeast of Anchorage and reached from the Glenn Highway,is a popular fish- ing,boating,and hunting area.The lake is a destination point for boaters and provides access into the upper Susitna and Tyone ri vers.Boaters also fJ oat down,the Sus itna Ri ver from the Denali Highway bridge and up the Tyone River into Lake Louise. North of the Susitna project,the BLM maintains the 4.4 million acre (1.76 million ha)Denali Planning Block.This area encom- passes much of the Denali Highway a~d includes several archeolog- ical sites of national significance.BLM maintains several small campgrounds and picnic areas along the highway,boat launches,a E-7 -11 2.1 -Statewide Setting canoe trail on the Susitna River,and two campgrounds at Tangle Lakes.The major campgrounds are located at Brushkana Creek and Clearwater Creek.' The Susitna Flats State Game Refuge to the north of Anchorage and the Chugach National Forest to the east also absorbs a large por- tion of recreation demand for the southern portions of the south- central region.A great many recreationists from Anchorage use the world-famous Kenai Peninsula parks,over 100 miles (160 km) south of the city.These areas offer the widest range of Alaskan recreation.Features include superior fishing,big game h'unting, scenic driving,and skiing as well as lake and saltwater recrea- t ion. Numerous private facilities in the region provide additional for- mal and informal recreational opportunities.These include re- mote lodges,cabins,restaurants,airstrips and flying services, guide services,white-water rafting,and other boat trips. The town of Ta 1keetna,located on the confl uence of the Sus itna and Talkeetna rivers,serves as the operations center for Mt. McKinley mountaineering expeditions.People from all over the world come to this old mining town to fly out to the mountain base and other recreational points.In addition to mountain climbing,other recreational activities which serve as Talkeetna's economic base include hunting,fishing,guiding, tours,and sightseeing. A listing of other existing and proposed relevant regional rec- reational opportunities is included in'Appendix 7.A. 2.1.4 -Existing Regional Recreation Use Outdoor recreation is a way of life in Alaska.According to a recent survey (Cl ark and Johnson 1981)which is used by recrea- tion planners in Alaska to assess demand,the wide variety of recreation opportunities available is a major reason that people move to and stay in Alaska.Only self-reliance is considered more important,and proximity to the wilderness was the third most important reason Al askans gave.The percentage of Al aska IS· population that participates in outdoor recreational activities is among the highest in the nation.According to that recent statewide recreation survey,59 percent of the respondents in the south-central region reported that they enjoy dri ving ·for pl eas- ure.Over half of the respondents walk or run for pleasure and a full 42 percent go freshwater fishing.Table E.7.4 ranks the percentage of participation in various inland activities within the region.South-central residents rank their favorite recrea- tion as fishing,tent camping,hunting,trail-related activities, E-7-12 - ""'" -. - ~i 2.1 -Statewide Setting baseball and bicycling in that order (ADNR 1981a).In contrast, tourists in the area have indicated driving for pleasure as their favorite activity followed by camping,hiking,and sport fishing (Alaska Division of Tourism 1981). Table E.7.5 outlines the total visitor count summary for Alaska State Parks from 1978 to 1980.The Mat-Su and Copper Basin Park districts constitute the Susitna River Ba~in as it was analyzed for those data. Over 389,000 visitors came to Alaska for pleasure trips in 1977. This represents a 13 to 15 percent annual growth rate since 1964. Recreational growth rates are difficult to predict with confi- dence,since they rely on many variables,including world eco- nomic conditions.However,the State Division of Tourism proj- ects that in the year 1985 up to 1,000,000 tourists will visit Alaska.The reasons tourists give for being interested in Alaska were studied in a poll by GMA Research Corporation in 1980 (Alaska Division of Tourism 1981). Main Reasons for Interest in Alaska -Scenery,mountains,forest,outdoors -Unique,different from other places -People,Native cultures,Eskimos -Unspoiled wilderness -Other responses including:curiosity, adventure,vastness,wildlife,fishing, and hunting Percent 40 25 10 10 15 - In terms of numbers of visitors,the most important areas -in Alaska for out-of-state tourists are the Gulf of Alaska, Anchorage,and the Denali National Park which is within 80 miles (133 km),of the future Susitna damsites. 2.1.5 -Recreati on Trends ./'-~ ( South-central Alaska is reportedly experiencing,overcrowdin_g.)in some existing recreational areas near Anchorag~due to r~~nt population growth.Assuming that the present rec'r-aation~c par- ticipation rate remains constant,the region will Continue to experience a significant annual increase in demand equal to the rise in population.However,recreation participation in the United States and Alaska may increase faster than the population \ if current trends continue.Alaskans have increasing amounts of lei:5'tJ~tinieand flexible working schedules which enable them to stevote f'crn-g-e,r periods of time to recreation.This may result in ~ger ltr:JpS at greater distances from the urban centers.In recreift"ional areas which receive up to 50 percent of thei r users [-7-13 2.1 -Statewide Setting from the cities of Anchorage and Fairbanks,intensity of use in- creased three-fold in the late 1970s and the recreational season has lengthened by several weeks (ADNR 1982a). According to the South-central Regional Plan,sports fishing license sales increased 40 percent from 1975 to 1980.Increased use of accessible streams has caused overcrowding in popular fishing areas throughout the region and in particular those streams nearest the urban centers.Interest in boating is also rising.Sales of motorized boating equipment has increased sig- nificantly in the late 1970s.The Knik Kanoers and Kayakers Club of Anchorage has reported rapid growth in recent years.There is evidence,as well,of a rapid increase in winter recreation,as surveys of winter recreation equipment sales over the last seven years show (Clark and Johnson 1981). A statewide 1981 publ ic survey (Cl ark and Johnson 1981)polled i /south-central residents to determine the recreational needs and I\[priorities of the region.Twenty-five percent of the residents \ \responded that they woul d mos.t 1ike to do more fi shi ng,12 per- \ cent more tent campi ng,7 percent sai d hunti ng,and 8·percent said motorboating.They said bad weather,lack of free time, Ilclosed seasons,overcrowding,and high transportation costs are ill~.ithe most common reasons that prevented them from increasing their I.activities.When asked what priorities the State Parks Depart-~ment should have for future development,residents advised the department to acquire more campgrounds and hiking trails,and to develop recreation trails,backpacking campsites and boat trails. However,they woul d prefe~to ma i nta in existing wi 1 derness areas,not expand these /~ Also in the 1981 surve~,61 perc~of the south-central resi- dents are reported to "\ike more ~creational opportunities at weekend travel distances,and 62 p rcent would 1ike more com- munity recreational develo ~nt.Wh n asked how many hours they would travel for weekend recrea ion,17 percent said over 4 hours,11 percent said over 5 hours,and a full 20 percent were willing to go over 6 hours from home for a weekend trip.This is generally believed to be supported by existing travel patterns and is an important concern for recreation planning at Susitna, since the site is 'over 5 hours from both Anch~rage and Fairbanks. The identified needs and desires of south-central residents will be included in programming recreation for the Susitna project. The features that Alaskan residents most desired in out-of-town recreational areas include (ADNR 1981): E-7-14 \\ \\ "iJ\)/ ~\~ - ~, - - - - - 2.1 -Statewide Setting Feature -Fi shi ng areas -Water access Developed camping and picnic sites -Undisturbed natural areas -Hunt i ng areas -ORV trail s 2.1.6 -Future Facilities %of Population in Favor of Features 95 91 91 88 87 7 .- - In 1982 the State Parks Division publ ished an aggressive plan to expand recreat i onal opportun it i es withi n t he south-central region.This plan reflects the role the State Parks Department has in providing outdoor regional recreation,and attempts to respond to all of the existing unsatisfied demands and projected needs of the region (see Figure E.7.3 and Appendix 7.A for future regional facilities.) State Parks development priorities include several recreation sites that will affect the Susitna Hydroelectric Project Recrea- tion Plan.They are included in Appendix 7.A and comprise the following: ,~- Dena1 i State Park,to the west of the Susit~oject,has been studied as the site of the Tokositna Resort which would offer first-class hotel facilities,cultural attractions,commercial developnents,indoor recreation,alpine skiing and other winter sports as well as the traditional outdoor recreation a1 ready offered in the park.While this project is no longer under active consideration due to uncertain feasibility,preliminary studies estimated a potential for over 2 million visitor nights and 300,000 day visitors by 1985.This year-round resort would have become the premier recreation destination in Alaska.Should this potential project be developed,it would accommodate signif- icant portions of projected recreational demand within the state for both residents and tourists. In other areas of the Dena1 i State Park,additional picnic areas, campgrounds,boating facilities,and trails are being developed. Along the eastern portions of the park,trai1heads have been designated in conjunction with rail road stops;these trails would connect into the westernmost portion of the Susitna study area. The Lake Louise Recreational Area southeast of the Susitna study area is a popular boating and fishing area.Current expansion plans will add 300 acres (120 ha)to the existing 50 (20 ha)and include several campgrounds,boating facilities and canoe portage E-7-15 2.2 -Susitna River Basin trails.This development is a high priority item,since the lake area and existing improvements are experiencing heavy use.The adjoining Susitna Lake and Tyone rivers have been identified as boating recreation areas for possible campground development at a 1 ater time.Th is area is 1 inked to the Susitna Ri ver via the Tyone River,and boaters currently travel between the areas. The State Parks Division has identified the Talkeetna Ri~er as a possible State Recreation River.These lands have been selected by the Cook Inlet Region,Inc.(CIRI)Village Corporations for conveyance.The proposed recreation area woul d extend from the river mouth at Talkeetna up to the confluence of Talkeetna and Prairie Creek.It is possible that new legislative designation will not need to take place,but that means to protect the river will be sought under existing legislation. Several other proposed new parks and park expansions given a high priority by ADNR are listed in Appendix 7.B,Future Regional· Recreation Opportunities. 2.2 -Susitna River Basin 2.2.1 -Background During the past decade,the middle Susitna River basin has been studied and evaluated by numerous state and federal agencies.It has not met the criteria required for inclusion in any of the following recreation and conservation programs: National Park -Preserve System; -National or Historic Landmark Status; -Wilderness Preservation System; -National Trail System; -National Forest System;and -State Pa rk System. The area has not been studied for inclusion in the National and Sceni c Ri ver System.No furtherstudi es are known to be under consideration.Since no federal withdrawals were made,both the state and Native corporations have selected lands in anticipation of development and use. 2.2.2 -Existing Facilities and Activities The middle Susitna River basin encompasses over 39,000 square miles (101,400 sq km).For the purposes of the recreation plan, the area to be studied is generally defined by Parks Highway on the west,Denali Highway to the north,Susitna River to the east and a line approximately 20 miles (33 km)from the Susitna River on the south. E-7-16 - ""'ll ""'" !P!'\I ..... -I - ,.... i 2.2 -Susitna River Basin This portion of the middle Susitna River basin has yet to be developed as a significant recreational resource.Presently,the level of use is restricted by several major llmitations.The area is immense and isolated,access is difficult,and potential users live great distances away.Small planes are the most com- mon form of recreational access and use the few gravel airstrips which exist in the area.Floatplanes also land on the larger 1 akes and ri vers.Auto access consi sts of a few a ll-terrai n vehicular (ATV)trans and rough roads into the settled areas. Boat access is possible to a limited extent,since various types of water craft float and motor along the Susitna above Vee Canyon and below Devil Canyon.Boats also use the Tyone River for access into the area . As a result of these limitations,people who do not live nearby utilize the area only on weekends or on other overnight visits. Past development within the area has been closely tied to the needs of the small local population for food,income,subsis- tence,and recreation.Existing facilities are very dispersed, and actlvity occurs at a low level of intensity (see Figure E.7.4 for existing recreation patterns.) (a)Facilities No public recreational facilities presently exist within the study area except for the roadside facilities on the Denali and Parks highways. Along the Denali Highway,BLM maintains several small road- side campgrounds and picnic areas.A boat launch,canoe trails,and two campgrounds were also built at Tangle Lakes. The most important of these facilities relevant to the Susitna Hydroelectric Project recreation plan is the 33-site campground at Brushkana Creek and the boat launch located at the highway bridge over the Susitna River. Existing private recreational developments within the study area include clusters of small seasonal cabins and commer- ci al lodges.There are approximately 110 structures within the study area.Chapter 9,Land Use,includes a comprehen- sive table of all structures within the area and lists their use,mode of access,.location,and condition.The major concentrations of residences,cabins,and other structures are near Portage Creek,High Lake,Gold Creek,Chunilna Creek,Stephan Lake,Cl arence Lake,and Big Lake.Most are used in association with hunting,fishing,and other recrea- tion activities.Some of these locations are accessible by ATV trails,but most are located near dirt airstrips and large water bodies for access by plane.Those structures E-7-17 2.2 -Susitna River Basin being utilized for recreational activities are located in Figures E.7.6,E.7.7,and E.7.8. Portage Creek is a mining area with some summer cabins;it contains 19 cabins and several other structures.Other developments at Chunilna and Gold creeks are primarily min- ing establishments.There are 10 small cabins along the Susitna Ri ver banks which are currently used by transient recreationists.The three commercial lodges in the area are located at High,Tsusena,and Stephan Lakes. Stephan Lake Lodge,located south of the Susitna River,is the largest of the three commerical lodges.It includes 10 main structures and seven additional outlying cabins,and receives the greatest number of visitors annually.Serving a predominantly European cl ientele,it offers a variety of outdoor recreation activities in a wilderness setting in- cluding hunting,fishing,and float trips down the Talkeetna and upper Susitna rivers and.Prairie Creek. High Lake Lodge is t~e second largest lodge complex with 11 structures (see Chapter 9,Land Use -Existing Structures). It is located northeast of the proposed Devil Canyon damsite at High Lake.Historically,this lodge has provided guests with services that are simil ar to Stephan Lake Lodge for hunting and fishing activities in a wilderness area.The lodge is currently being utilized by Susitna project per- sonnel doing field research.Several small outlying cabins located along Portage Creek and the Susitna River are util- ized by visitors to High Lake Lodge while on hunting and fishing trips. Tsusena Lake Lodge is located north of the proposed Watana damsite and Tsusena Butte and adjacent to·Tsusena Lake. This lodge,with three structures,is used primarily by the lodge owners and members of their families and friends.The majority of use occurs duri ng the summer and fal J months with little or no use during the winter months. The existing trail systems were built for access by prospec- tors,hunters,trappers,and fi shermen (see Tabl e E.7.6 and Figure E.7.4 for a listing of major trail locations,condi- tion,and use.)At present,these trails and rough roads accommodate horses,tracked vehicles,rolligons,dogsleds, and hikers.They connect a few scattered recreational developments and mining settlements and the camps used for researching the area's hydroelectric potential.Trails radiate from these scattered structures out to ai rstrips, lakes,and adjacent fishing streams. E-7-18 ~ I - '"'"" - - - - ,- 2.2 -Susitna River Basin BLM is currently developing regulations for the management of the public trails located on lands which the Native cor- porations have selected.A total of six easements have been identified within the study area (see Exhibit E,Chapter 9). These include an access trail 50 feet (15 m)wide from the Chulitna wayside on the Alaska Railroad to public lands immedi ately east of Portage Creek;a state site easement and trail easements on Stephan Lake;and an access trail running east from Gold Creek. .... .... .... r I (i )Trail Information The following trail information was reported in the unpublished Area Notes (ADNR Division of Research and Development 1980)prepared as part of the Upper Susitna Basin Recreation Atlas . The Snodgrass Lake Trail begins at the Denali Highway near the Susitna bri dge and proceeds south to the lake.The trail reportedly receives use during the summer,autunn and winter months.Recreational activities include:moose,brown bear,and caribou hunting;fishing;camping;off-road vehicular use; picnicking;wildlife observation;berry picking; snownobil-ing;overnight camping;and cross-country skiing . The Portage Creek Trai 1 follows a sled road from Chulitna to Portage Creek.Hikers access the trail at the Alaska Railroad stop near Chulitna.The trail is used in the autumn,summer,and winter months and is popular with hunters of moose,caribou,brown bear and black bear,as well as hikers,campers,fisher- men,photographers,and berry pickers.Portage Creek also receives a light level of fishing effort.Most of this trail traverses CIRI-selected lands. The Butte Lake Areai s used during summer,winter, and autumn months.There is a CAT trail,also iden- tified by Terrestrial Environmental Specialists (TES) in its Susitna Land Use Report,that connects the Denali Highway and Butte Lake.This trail is used by skiers,snowmobilers,hikers,fishermen,berry pickers,and campers.There is some fishing effort for grayling and lake trout on Butte Lake.The Butte Lake area is a duck,geese,and swan birding area. The Brushkana Campground at Mile 105,Denali Highway, is reportedly one of the few known habitat areas for the Smith's Longspur. E-7-19 2.2 -Susitna River Basin A trail runs from the town of Denali downstream along the east bank of the Susitna River.At the conflu- ence of the Susitna and Maclaren rivers,the trail continues east up to the Maclaren River and then turns south.This trail connects to other trail s leading to Lake Louise or Crosswind Lake and ulti- mately to the Glenn Highway.It is used by off-road vehi cl e dri vers;sno\rwffiobi 1ers;hunters of cari bou, moose and brown bear;fishermen;and possibly dog sledders.Bird watching is also popular along the Denal i Highway between the Susitna Lodge and Swamp- buggy Lake. (b)Activities Aside from the isolated lodges,cabins and trails which con- stitute a commitment to a particular site,the predominant recreational pattern is dispersed and non-site-specific. Activities include the consumptive recreations such as hunt- ing,fishing,food gathering,and rock hounding.River- related activities include various types of power and non- powered boating and rafting.Other dispersed activities currently practiced in the area are camping,hiking,cross- country skiing,and photography. (i)Sports and Trophy Hunting This is a traditional activity in the middle Susitna Bas·j n.The three commerci al lodges in the area serve as bases for hunti ng groups that fly in for gui ded trophy hunts.The lodges typically handle 15-20 guests at a time and jointly total 120 guests per season (TES 1982a).In addit ion,many hunters fly into the 1arger 1akes and utili ze the small 1akesi de cabins for hunting trips.Hunters also use ATV vehi cl es and horses to ga in access to more remote areas.The most popular big game include Dall sheep, moose,caribou,black bears,and brown bears.Alaska Department of Fish and Game data indicate that the recreation study area had about 600 hunter-days for moose,caribou and sheep in 1981. (ii)Fishing This is an activity which frequently occurs here in association with other activities such as hunting, boating,and camping.Local residents have long enjoyed high quality fishing in area lakes,streams and rivers.They commonly fly into the 1 arger 1 akes E-7-20 ..... 2.2 -Susitna River Basin for all-day or weekend trips.Lake fishing is con- centrated at Fog,Cl arence,Butte,Watana,Tsusena, Deadman,Big,and High Lakes;while stream fishing occurs mostly along the creeks accessible by land such as Portage Creek. .... Salmon migrate the Susitna up to Portage Creek just below Devil Canyon.Both guided and individual fi sh- ing trips are popular here.Considerable salmon fishing also occurs in Stephan Lake and Prairie Creek as boaters travel downstream on the Talkeetna River from Prairie Creek.Other popular salmon fishing spots i ncl ude lower Portage a/nd Chtmi 1na creeks and lndi anRi ver.Lack of road·access is an important limiting factor on fishing,and little stream fishing occurs in the adjacent lands.There are many popular salmon fishing areas farther downstream on the Susitna River and its tributaries. little site-specific data are currently avail- on food-gathering patterns within the study Some berry-picking areas are known near to the east of the study area and several along the Denali Highway. Very abl e area. Chul itna more are Food Gathering(i ii ) - (i v)Boating I""" r i Summer boating occurs on many of the larger lakes as recreationists fly in.Riverboat and guide services are offered from Talkeetna and from the various lodges downstream from Devil Canyon.The Sus itna River is considered navigable up to the mouth of Portage Creek by a vari ety of craft i ncl udi ng rafts, canoes,airboats and riverboats. The Susitna River is used for fishing and access to hunting.Boating activity takes place south of the study area near boat launches at Willow Creek,Kash- witna Landing,Sunshine Bridge,and Talkeetna.The upper Susi tna above the proposed reservoi rs is cal m and provi des good _boat i ng and canoei ng.Boaters reportedly float the river from the boat launch on the Denal i Highway down to the Tyone Ri ver,some then motor up to Lake Louise at the Tyone's source.Other boaters continue down the Susitna to the gaging sta- tion above Vee Canyon where they pullout and portage to C1 arence Lake for fi shi ng.The upper Talkeetna E-7-21 2.2 -Susitna River Basin River in the southern portion of the study area, rated Class IV,offers some of the finest rafting ~nd white-water kayaki ng in Al aska.Tal keetna Ri ver is not easily accessible by land;airplanes usually land at-Stephan Lake.It is reported that four to five parties per year,consisting of three to six persons, are air-lifted into Stephan Lake.They float Prairie Creek to the Talkeetna River and down to the town of Talkeetna where they enter the Susitna River or pull out.The trip usually takes 2 to 3 days (Knik Kanoe and Kayg,~__,.Cltlh~~-Pe~s.ooal communication,Mary Kay Kess-i-(rn~•_._'-~._-_.....-----.//.I J ----..... ./'" ,/Two to three parties of a few individuals vent /down through the rapids of Devil Canyon each yea,I This wild stretch of river,which roars through 11 I miles (18 kill)of a narrow vertical canyon,is des-i cribed by veteran kayakers as the Mt.Everest ofIkayaking.It is generally considered by kayakers to /1fC I be a Class VI rapids on the international white-water yY\scal e.Cl ass VI has been defi ned as "l i fe- .threatening to skilled boats.men with good equipment."

'"(v)Cross-~y Skiing ~._""",,-=~...--,,- Cross-country skiing takes places in the area,par- ticularly near Denali Highway.Occasional tour pack- ages have been offered by the local private lodges. Snowshoeing has also become a purely recreational sport here.A limited amount of recreational trap- ping takes place on the south side of the Susitna Ri ver near Stephan and Fog 1 akes as well as on the north side near Tsusena Creek and Clarence and High lakes.In the winter,dogsleds and snowmobiles travel through the area.They most commonly use the frozen river as trail.Their activities are report- edly centered around Trapper Creek and Talkeetna to the south. 2.2.3 -Future Activities and Facilities Should the Susitna Hydroelectric Project not be developed,the major obstacles which have limited past recreational activities wi 11 cont inue to do so in the future,al though Nati ve E-7-22 - - -I - - ..... - ,... - - - - ..... 2.2 -Susitna River Basin corporations may seek to develop their lands for recreational uses.Unless vehicular access is developed in the study area, no major shift in the existing low-level recreational patterns is ant ici pat~",_"...<",-,._ ,~.'''''''''<.'''''i.''i?<-l __.,._,."'....,..o ••,,_,,.·_v_~-,."-_·'"'·_·~_·,,···>·~···_~"'·_"-..--.~~_.__._._,.,,-~""'~~"',..---""_-.'......---..........T~arties which wi'}c.k.!:~~future recreational activities(and i\, fev~i opment in the study area i ncl ude the Al aska state gove'r,n, !{11ent,U.S.BLM,several Native corporations,and various private-::-"" handholders.\~~~~;:C;le~n~~th reased ·pl~~~:~:~~·~;:c~~~~~~) opportunities from Alaska residents,will largely determine future land use patterns.The exact nature of specific activi- ties and developments is difficult to predict since land owner- ship decisions are in abeyance and are not likely to be resolved for several years. (a)The Native Corporations The Native corporations have selected much of the land adja- cent to the Susitna Ri ver and along Portage Creek and Talkeetna River.The corporations have not identified any specific plans for development if the hydroelectric develop- ment does not occur;however,development possibilities which have been discussed include mineral extraction and recreat ion-home 1and development.Access appears to be the prime determinant for development decisions.At present, two small,improved vehicular trails provide access to both the northern and southern sides of the river. The Matanuska-Susitna-Beluga Cooperative Planning Studies have analyzed the demand for recreation-home lots within their planning area,which includes the Susitna study area. They have projected a demand for 29,000 acres (11,600 ha)of new lots by the year 1990 assuming a population growth of 65,000 people.This is an exceptionally high demand level relative to resident population figures and reflects the region's popularity for recreation-homesites with Alaskans from other areas.The lands selected by Native corporations near the Susitna Ri ver meet all of the aesthetic criteri a for prime lots according,to the study (ADNR May 1982).How- ever,without improved road access and considering the landis building limitations,the property was given a rating of moderate capability,and sales are unlikely to be signif- icant.Native corporations have also expressed a preference for land leasing rather than sale. E-7-23 2.2 -Susitna River Basin (b)BLM Policies BLM policies for the Denali Planning Block,shown in Figure E.7.5,reflect their goal of increasing recreational use. Their plans include road improvements to the Denali Highway and additional roadside improvements such as new camp- grounds,picnic areas,and pull-outs.BLM is projecting an increase of the average annual daily traffic (ADT)along the highway to 130 in the year 2000;the existing ADT is 50 cars.Formal designation of BLM land for additional ATV use appears to be no longer under consideration,however. BLM 1ands have recentl y been opened to mi nera 1 expl orati on and mining entry which will attract additional people to the area,and if significant deposits are discovered,this will greatly affect future recreational patterns. The private lodge owners in the area have not indicated any plans for expansion.The existing levels of use are small and are not expected to change substantially. E-7-24 .... .... , I ..... - 3 -PROJECT IMPACTS ON EXISTING RECREATION I Impacts that the Susitna Hydroelectric Project will have on the exist- ing recreational patterns'are of two types:indirect or direct effects.Indi rect impacts are those re1 ated to changes in recreati on user demand levels.These include the impacts of construction worker recreation and the influx of recreationists as a result of the new road openings.Direct effects are defined as those which relate to physical changes in the natural resources which constitute recreation settings. Impacts to these settings might either increase or decrease the desir- ability and probability of existing recreational types and activity levels.They may also make possible new types of activity.Section 3.1 deals with direct impacts and discusses each major project develop- ment separately.Constructi on and ope rat i ona1 impacts are a1 so dist i n- guished in each case. 3.1 -Direct Impacts of Project Features Within the areas to be disrupted,existing recreation consists primar- ily of dispersed and low-level activities such as hunting,fishing,and hiking.These patterns will be somewhat impacted by increased activi- ty,environmental disruption,and restricted or increased access.How- ever,because of their inhe~ent mobility and nonsite specificity,these activities,for the most part,can be absorbed in surrounding land- scapes. In most cases,the important issues are the potential impacts upon rec- reational resources rather than on specific existing activities.The major components of recreati ona1 setti ngs consist of fi sh,wil d1 ife, and botanical habitats and the aesthetic character of the landscape. Detailed discussions of the impacts on these resources can be found in Chapter 3,Fish,Wildlife and Botanical Resources,and Chapter 8,Aes- thetic Resources of Exhibit E.References will be made to these Chap- ters as needed. 3.1.1 -Watana Development (a)Construction Construction of the Watana dam and related features involves construction of two cofferdams and diversion of the river. It includes clearing of forest land,dredging of the river, excavation of borrow sites for damfill material,blasting for the underground powerhouse and other features,as well as other heavy const ruct ion acti vit i es at the dams ite.An access road and temporary transmission line will be con- structed from the Denali Highway and construction camps built near the damsite.(The access road is discussed in Section 3.3.)The 38,OOO-acre (l5,200-ha)reservoir area will be cleared of trees prior to inundation.It is antici- pated to require three years to fill the entire impoundmentrarea. E-7-25 3.1 -Direct Impacts of Project Features The primary impacts of initial construction activities ex- tend beyond these relatively small areas being physically disturbed.A significant change in image will affect a large area as the prevailing wilderness character changes to intense activity and heavy construction.This is an un- avoidable impact of development and can only be partially mitigated by careful management of the remaining lands. (i)Land-Based Recreation Land-based recreational activities and resources with- in areas that Watana construction will affect have a 1 ready been somewhat modi fi ed by the presence of project researchers who currently 1 ive and work in the vicinity.Although their low-level recreational activities have not caused any known adverse impacts, that area is no longer perceived as a wilderness setting. It is anticipated that during construction all work areas associated with Watana Dam will be closed to the recreational public.Thus,any existing activities will be el iminated for the duration of constructi on. These recreational activities consist of hunting and fishing in the area and can be absorbed by other pub- lic lands for the duration of work.However,if con- struction practices cause permanent degradation to the recreational environment or fish and wildlife habi- tats,these activities could be lost permanently. This is already anticipated in the areas north of the damsite where a small,concentration of black bears has been identified. The 38,OOO-acre (l5,200-ha)reservoir will eliminate 10 small riverfront cabins which are used seasonally by hunters,fishermen,and other recreationists who arrive by boat or plane.The impoundment wi 11 also inundate a large area of prime habitat for such wild- life as wolverines,moose,and black bear,and pos- sibly disrupt migration of the Nelchina caribou herd. While no direct correlations can be drawn between these losses and a.reduction of hunter days,it can be expected that,in general,fewer hunters,particularly trophy hunters of black bear,will be attracted to the area or they will be less successful.Specific impacts and mitigations for this loss are di~cussed in Exhibit E,Chapter 3,Fish,Wildlife,and Botanical Resources. E-7-26 - - -I - - 3.1 -Direct Impacts of Project Features (i i )Water-Based Recreation Fishing impacts will occur as a result of the effects of riverine construction (see Chapter 3)~The Tsusena Creek mouth and Susitna Ri ver channel s will be affected by gravel removal during construction.Down- stream recreational fishing may also be negatively affected during the three-year filling period in which summer flows will be reduced.Twelve sloughs utilized for spawning and/or rearing will potentially be im- pacted,and the fi shi ng experi ence may be dimi ni shed by the lower water levels.Existing fishing activity upstream from the Watana Dam will also be altered. The i nundat i on of the lower reaches of cl ear-water tributaries will eliminate existing fishing spots for this area of the river. - - The existing level of boating activity both downriver from Devil Canyon to Talkeetna and upriver from Watana will be largely unaffected by Watana construction until vegetation clearing,gravel removal,and burning begins.When filling of the Watana reservoir begins water level s downstream will decrease duri ng summer recreation months.Depending on the precipitation and natural water level during filling,the reach of the Susitna 1 to 3 mil es (1.6 to 5 km)below Sherman [about 6 to 9 miles (10 to 0.15 km)below Gold Creek] may be difficult to navigate.Boaters who currently venture up the river to Devil Canyon and Portage Creek may find this difficult to do. (b)Operati ons - (i )Land-Based Recreation After construction,the land areas associated with the Watana dam will either be rehabilitated or utilized for operations facil ities and a permanent townsite. Rehabilitated areas may return to use as recreational areas.The operations areas may be permanently un- available for public recreation as it currently exists.A visitor center is proposed for the damsite. The presence of workers and thei r fami 1 i es will al so continue to impact the recreat ional resources.There are recreational facilities proposed "in the village for these people. Once operation of the Watana Dam facilities begin and the recreational publ ic gains access to the area via E-7-27 3.1 -Direct Impacts of Project Features the Watana access road,sightseers wi 11 be attracted to the damsite.The higher user levels will affect the existing recreational patterns of hunting and fishing by increasing the hunting and fishing pressure on the wildlife,fisheries,and botanical environment (see Chapter 3). (ii)Water-Based Recreation Potential fishing impacts after construction will also be dependent on water quality and quantity.As flows stabilize and as silt is trapped in the reservoir,it J i s ant ici pated that the Susitna downstream from the dam will clear and become more fishable than existing levels,particularly for coho and chinook salmon. Downstream from Watana Dam,boating may continue to be affected by reduced.water flows after construction. Water levels will be lower at Gold Creek during June, July,and August.Sunshine and Susitna farther down the river will be much less affected. However,kayaking on the Devil Canyon Rapids may con- tinue and will be less hazardous.Operational impacts of the d am and reservoi r on exi st i ng boat i ng recrea- tion are related to the quantity,schedule,quality, and temperature of water retained in and released from the reservoir. The reservoir drawdown will reach its low point in May,and the lake will fill from June through August, peaking in early September. The lake shorelines exposed during low water will have 1 arge mudfl ats and steep banks of tree stumps and slumping soils.This situation will severely limit the development of the reservoir as a major recrea- tionalopportunity.A lack of fish population,silty waters,and cold water temperatures in the reservoir reinforce this limitation.Safety will also be a concern for future boaters.The 1 ake l s great 1ength and breadth may lead to treacherous conditions during periods of high wind. The recreationists that currently float this stretch of river will find in future a 54-mile (90-km)long lake in place of a rapidly flowing river.With a loss of current,boaters wi 11 need manual or mechanical propulsion to navigate the new lake.New activities E-7-28 - - - - - - ..... 3.1 -Direct Impacts of Project Features such as floatplanes and large motorized boats will increase as recreationists take advantage of the rec- reational setting created by the lake.Access through Vee Canyon from upriver will be easier when the rapids are flooded.The lake experience will be quite dif- ferent in character from existi ng conditions (see Chapter 8,Aesthetic Resources)and can be expected to attract a di'fferent type of recreational user. 3.1.2 -Devil Canyon Development (a)Construction Construction of the thin,concrete arch Devil Canyon Dam and related features includes a high-level bridge across the canyon,cofferdams,diversion of the river,land clearing, blasting,and a major concrete mix plant at the damsite.In addition,a railroad spur will be constructed from Gold Creek;a 37-lllile (3120-ha)road built between Watana and Devil Canyon;and construction camps built near the dam- site. The 7800-acre (3120-ha)reservoi r,unl ike Watana,will be relatively narrow,and largely confined within the canyon walls,particularly in the downstream reaches,and will re- qui re 1 ess clearing of . .acts re- sul t i ng from it s ",_-,=urrwlTrrH:!the loss of 11 m1 18 km)of C river rapids.This is an irreplaceable los .~of ,F carce worldwide recreation resource.Expert kafrkers /~.E~e come from around the world to attempt this trip.Al- /'t,hough the actual number of kayakers are few (2-3 part i es "",,/per year),it does not diminish the significance of the ,/loss.An additional 32 m"iles (53 km)of river canyon stre~m from Devil Canyon will also be lost. ~---With theG8f;)t i OR sf teiilporary impacts on water qual ity during the cofferdam construction,no water quality-related recreational impacts are foreseen.Filling will take about two months and,depending on season and rai nfall,wi 11 not appreciably affect fiow rates.No further impacts are anti- cipated on downstream fishing and boating activity. The primary impacts of Devil Canyon construction on adjacent land-based recreation will be the conversion of a virtual wilderness to a construction area and residence for 3600 people.The land,which will become the primary areas of construction-related activity and storage,currently sup- ports numerous game animal s.The noi se and dust of con- struction and the disruption caused by heavy equipment E-7-29 3.1 -Direct Impacts of Project Features operations,along with the presence of large numbers of construction workers,will disturb wildlife habitats and recreation environment. It is anticipated that all hunting from project facilities wi 11 be prohibited (see Chapter 3).Fi shing activity wi 11 be managed by the state Department of Fish and Game.For purposes of enforcement,it is likely that all recreational access by project personnel will have to be managed during construction. (b)Operations Operation of Devil Canyon will cause only minor changes in flows from Watana operation flows below the dam,and it is not expected to further affect river recreation.. The Devil Canyon reservoir will have the same limitations that affect the recreational opportunities of Watana reser- voir,although smaller drawdowns and steeper sides will result in less severe mudflats.The proposed operating schedule wi 11 lower the reservoir up to 50 feet mid August to September each year.This shoreline will also be visually unattract i ve. After construction,the temporary village and camp will be closed and resident operators will be located at Watana Vi 11 age,thus eliminating the ingoing impacts of a large resident group of people. 3.1.3 -Watana Access Road (a)Construction Access improvements to be made for the Watana dam phase include 21.3 miles (35.5 km)of upgrading to the existing Denali Highway and 41.6 miles (69 km)of new road from the Denali Highway to the damsite.Other related developments include a small temporary construction camp near Brushkana Creek and several borrow sites along the new road. Dur-ing construction,approximately 90 large construction vehicle trips per day are anticipated on the new road and an additional 600 to 800 trips are anticipated from commuting construction workers (see Chapter 5). The entire route from Parks Highway along Denali Highway to Watana Dam will be open year round,allow-ing access along E-7-30 '""" ..." - - - - - - - ...... - 3.1 -Direct Impacts of Project Features the'Dena 1i Hi ghway segment whi ch is currently closed each winter by snow.The new road will provide vehicular access into a large area previously open only to off-road vehicles and hikers. These road improvements and acces_s into new areas wi 11 impact the existing recreational patterns and recreational resources in several ways.First,winter snowplowing along the Denali Highway will cause an increase in winter recrea- tionists using the area for cross-country skiing,snowmobil- ing,dogsledding,and other winter sports.The Denali road improvements may also make that area more attractive to rec- reationists during the summer months,and the increased traffic (700 to 800 ADTs during peak years)of commuters, truck drivers',and new local residents will introduce other potential users to the recreational opportuniti es adjacent to the highway.Increased recreational activity can be expected to follow existing recreational patterns and would take the form of increased roadside camping in old gravel pits along the road,as well as hunting,fishing,and hiking t ri ps • The new Watana access road passes through an area whi ch presently has a very low level of recreational activity. Construction activities will not,therefore,directly affect any major recreation,since the hunting,fishing or hiking whi ch mi ght have occurred woul d eas'j ly be absorbed by the surrounding area.A more important concern is the alignment chosen for the new road.The final road location should avoid specific areas which are known to be sensitive envi- ronments and which would experience undesirable pressure from recreat ioni sts if made too easi ly accessi bl e.These ,areas are discussed in more detail in Chapter 3 of. Exhi bi t E. The alignment should also aVQid disrupting areas which are known to be popular recreation settings and those which are identified in this plan as important potential recreation settings.'For example,Tsusena,Butte,Deadman,and Big lakes include several existing recreational structures. The present proposed al ignment has been adjusted through consultation so that no known recreational settings will be negatively impacted by the access road. (b)Operations The Watana access road will not be open to the public during construction.When work is completed at Watana in 1993,a E-7-31 3.1 -Direct Impacts of Project Features decision will then be made regarding public access.It is assumed that the road will be officially opened for public use in 1993. Once the Watana road has been constrlJcted and workers and truck drivers begin travel ing back and forth,the road will attract recreationists and off-duty construction workers and families.Unless a control point and physical barrier are placed at the DenalijWatana road junction to limit access or other controls provided to deal with this attraction,rec- reational activities such as roadside camping,hunting,and fishing along Denali Highway will spring up prior to the official 1993 opening. These activities are not inconsistent with existing recrea-, tional patterns.The most significant potential impact would occur if overuse of popular areas resulted in degrada- tion of the recreational resources such as fishing streams, wildlife and their habitats. 3.1.4 -Devi 1 Ca nyon Access Road (a)Construction This 37-mile (60-km)road connecting the Devil Canyon dam- site to the Watana damsite will be built in 1992.Its use during dam construction will be primarily to transport equipment and personnel from the Watana town to the Devil Canyon construction site.The road traverses more difficult terrai n than the Watana access road and,as a result,re- quires careful design guidelines to control potentially significant impacts caused by large cut and fill sections. The selected road corridor w·ill affect the private recrea- tion lodge at High Lake.Passing within a mile of the development,the new access may change the character of the faci lity from a remote fly-in retreat to an auto-oriented facil ity.Construction will also have a significant impact on local game which is a prime visitor attraction for the lodge.No other recreati onal act i vit 1es presently occur in this area. Several borrow sites will be required to construct this road section.Impacts that these excavations and the road path itsel f will have on the existing recreational resources are primarily visual;thus,specific mitigations are discussed in Chapter 8,Aesthetics. (b)Operat ions After dam construction is complete in 2002,the Devil Canyon E-7-32 - - - - - "'"'" 3.1 -Direct Impact of Project Features r I road will be opened to the publ ic.Operations personnel will also travel to the Devil Canyon dam from the permanent townsite at Watana.Devil Canyon dam is expected to be more of a tourist attraction than Watana because of its striking design and impressive setting,and the road will function as an important recreational facil ity in that regard.Impacts of the public in this road corridor are similar to those in the Watana road,i.e.,increased use of pre vi ously remote hunting,fishing,and wilderness areas. 3.1.5 -Gold Creek -Devil Canyon Railroad (a)Construction Construction of a railroad spur to the Devil Canyon damsite will have little effect on existing recreational patterns. The areas which it will cross are largely unused.As with the case of road construction,care must be taken not to ~degrade the recreational setting. Along the chosen alignment,particular attention must be pai d to the segment which traverses the steep banks of the Susitna River in order not to degrade the river experience. Other segments which traverse diffi cult natural 1andscapes require site-specific considerations to achieve or maximize fitness. The major sources of impact i ncl ude cut-and-fi 11 operat ions, ,...,vegetation clearing,borrow excavations,and stream cros- sings. (b)·Operations After construction at the Devil damsite is completed,the rail spur will no longer serve project functions.At this time,it may become available for public use and will more significantly impact existing recreation. ~ I r- I The existing rail line to the west is currently used by rec- reationists to gain access to Denali State Park and sur- rounding lands in order to camp,hike,fish,hunt,etc. If access similar to the existing whistle stops were to be provided,a significant number of recreationists could be expected to utilize it.An added attraction of rail access is that it reaches the Devil Canyon damsite in 2 hours less time than would be required by car.The types of activities anticipated are similar to existing recreational patterns, with the possible exception of railside camping. E-7-33 3.1 -Direct Impacts to Project Features 3.1.6 -Project Area -Transmission Line The east-west connection from the two powerhouses to the intertie will be constructed alongside the Devil Canyon access road.Con- struction and future maintenance access will not be continuous along the line.Short trails will connect to Devil Canyon road. The presence of 100-foot (30-m)tall towers and cleared corridors will also reduce the area's appeal to recreationists as a wilder- ness area.The impacts of the transmission corridors on existing recreation patterns are primarily visual. 3.1.7 -Intertie and Stubs -Transmissfon Line Intertie construction is scheduled to begin in 1983.These lines and the future stubs from Healy to Fairbanks and from Willow to Anchorage are not anticipated to affect existing recreational patterns during construction or operation.Cleared transmission corri dors are commonly used by hunters and hi kers,and to the extent that these activities take place,recreation will be posi- tively impacted.Future studies are planned by the Power Author- ity to refine a recreation plan for these corridors. (a)Recreational Plan Studies The content of these studies will include: -Description of existing and future recreation; -Project impacts on existing recreation; Recreati on plan,-j nc 1udi ng recreat 1on opport unity i nven- tory and recreation opportunity evaluation;and -Plan implementation. (b)Specific Recreational Resources Specific recreational resources have been identified adja- cent to and within these corridors and include: -Healy to Fairbanks Stub Corridor Denali National Park .Proposed Parks Highway Scenic Highway Area -Healy to Willow Intertie Corridor Denal i St ate Park Al aska Rai lroad Small recreational trails E-7-34 .- - ,i'IIiIl : , - .- I - 3.2 -Indirect Impacts -Willow to Anchorage Stub Corridor •Nancy Lake State Recreation Area •Susitna Flats State Game Refuge •Iditarod Dogsled Trail •Several other recreation trails. 3.2 -Indirect Impacts--Project-Induced Recreational Demand 3.2.1 -Background Estimation of demand for recreation related to the Susitna Hydro- electric Project involves a number of complex and unusual circum- stances due to project location,characteristics of the project, and construction schedule.Added complexities result from a his- torically unpredictable regional growth pattern and lack of con- sistent and verifiable data concerning regional recreational pro- jections.Some of these circumstances include the following. (a)Al askan Recreational Envi ronment As discussed in Section 2 of this chapter,recreation in Alaska has unique characteristics due to the size of the state,the sparse population,the lack of roads,and long distances between facilities.The untouched wilderness con- diti ons and abundance of wil dl ife have attracted new state residents who enjoy the primitive recreational experience. Recreational patterns and uses do not follow those common at many hydroelectric projects in the lower 48 states.Usual recreational standards are not,for the most part,appli- cable in Alaska. (b)Lack of Recreational History Al aska became a state in 1959.The State'Department of Parks was formed in 1971.There consequently is not the long history and background of user data,public prefer- ences,demand data and so on which is usually availale to recreational planners.While important useful data are being generated by state agencies,the backlog of experience helpful to confidently make long-range predictions does not yet exi st. r ,.... ! (c)Uncertainty of Population Growth Population growth has two components--natural growth (sur- plus of births over deaths)and immigration.In Alaska,a major component of growth is immigration.Growth has been dependent in the past on external causes,such as the di s- covery and price of oil and the world economy,and is large- ly unpredictable by standard demographic methods. E-7-35 3.2 -Indirect Impacts (d)Population Mobility Alaska's population is among the youngest in the nation and unusually mobile.As energy,mineral development,and con- struction projects beg-j n and end,and as the 1arge propor- tion of mil itary and governmental personnel change assign- ments,the population composition changes.Public opinion and preference surveys can become quickly outdated as new immigrants replace former residents.These changes may not, however,appear in total population counts,because the num- bers may not reflect change in cornposition.Likewise,whole cycles can occur and be "missed"by the decennial census. (e)Cl imate Winters in the project area are long and severe.The Denali Highway,the only road penetrating the area,is not main- tained in winter.Smaller trails require special off-road vehicles for travel year round.Land-ing strips and lakes used for airplane access are also hazardous during the wi nter season.In addit i on,the short wi nter dayl i ght . period decreases available time for outdoor work,recrea- tion,and travel. (f)Setting The Susitna project area,compared with many other places in the United States,appears to be an outstanding recreation resource.However,in compari son with other resources in Alaska (with some important exceptions such as Devil Canyon Rapids),it is not unique. (g)Changing Land Ownership Major portions of Alaska have historically been owned by the federal and,more recently,the state government.Large portions of land are currently in the process of being dis- tributed to private Native corporations (see also Section 4.1).While many of the exact impacts of these actions are as yet unknown,it appears that the historical patterns of open recreational access to most lands within the state are changing in some instances. (h)International Travel Recent years have seen wide fluctuations in international travel patterns as the dollar,mark,yen and other cur- rencies have changed in value.As a remote and somewhat exotic tourist destination,tourist recreational levels in E-7-36 - - - - ...... """'f ro- I - - 3.2 -Indirect Impacts Al aska may vary greatly according to unpredictable outside influences. 3.2.2 -Assumptions The proposed recreation plan is designed as mitigation for rec- reational opportunities lost or negatively impacted due to proj- ect developments.The plan utilizes the recreational opportun- ities gained due to project development and provides for demand i~duced by the development. In projecting demand,a.number,_.Qt_sjmp.l~icf.y,i.n.g..assumptions have been-·-tltade'whi·ch·..··UDVi·d'te··--fh-e·effects of the uncertai nties in Alaska's recreational future.In addition to these assumptions, the recreation plan is phased and a monitoring program is pro- posed which will allow periodic adjustments to be made in the plan as assumptions and recreational conditions change. The following paragraphs include assumptions of these demand jections. -The population projections presented in Exhibit E,Chapter 5, are valid for Anchorage,Fairbanks-North Star Borough,and the Rail belt.Population projections for the Matanuska-Susitna Borough,as developed by the Borough in October 1982 and in- cluded by inference in the Railbelt projections,will continue to be val id. The project will be developed according to the general designs, operating characteristics,and schedule presented in Exhibit E, Chapters 1 and 2.Specifically,the current drav-K:lown schedules for Watana and Devil Canyon will pertain.The access roads from the Denali.Hi ghway to Watana and from Watana to Devil Canyon will be developed as ~urrently planned.A railroad spur wi 11 be bui It from Gol d Creek to Dev il Canyon and will be opened to the publ ic upon construction completion.An access road will not be connected from Devil Canyon to Hurricane. -The Power Authority will evaluate the decision to open the access road from Watana to the Denal i Highway at the time Watana construction is completed.For the purposes of this recreational demand projection and plan,it is assumed that the road will be opened to full publ ic access in 1993.If it is determi ned in the future that the road s houl d not be opened then,demand for recreation will be less than projected. Specific elements of the recreation plan will then be deferred as appropriate through the monitoring/implementation program. -The dams wi 11 have an inherent "curi osity"val ue whi ch wi 11 attract one-time visitors.Watana,in particular,is not E-7-37 3.2 -Indirect Impacts regarded as a major sustained attraction for repeat visitors. Devil Canyon Dam,the high-level canyon bridge,and the rail- road spur have more inherent attraction as potential recrea- t i on. Both reservoi rs wi 11 be characteri zed by sl umpi ng side wall s, scales,and landscapes on steep banks.Watana,in particular, will have large mudflats in many locations when drawn down. Neither reservoir will be an attractive recreational resource for sport fishing or boating.Watana,in particular,and Devil Canyon,to a lesser extent,will not be attractive resources to kayakers,canoers,rafters,and other small boat recreationists due to wind,chop,and temperature conditions. -The Denali Highway will be upgraded and new facilities will be installed as currently proposed by the Alaska Department of Transportation.The road will be kept open in the winter from the intersecti on with the Watana access road (approximately at Milepost 110)to the Parks Highway at Cantwell. -The Alaska Department of Parks,the U.S.Bureau of Land Manage- ment,the U.S.Forest Service,the Municipality of Anchorage, Fairbanks,and other appropriate governmental units will con- tinue to pursue their plans for increased recreational facil- ities e1 sewhere to serve increased demand.Many of the facil- ities documented in Section 2 will be closer to population centers than the Susitna project and will accommodate a portion of future demand by city dwellers. -The Native corporations will pursue a course of paced develop- ment of their lands,including selected mineral development, recreation home development,and commercial recreational devel- opment.These uses are assumed to be complementary to this recreation plan and are not anticipated to cause conflicts. -The Alaska Department of Fish and Game will adopt regulations appropriate to protect those resources within the project area and appropriate to the general levels of projected demand. Exi st i ng pri vate lodges wi 11 continue to operate ina manner and scale similar to 1980 operations.While some changes un- doubtedly will take place,they will not be of a scale to in- fluence demand projections significantly. -The Alaska Railroad will continue to operate as a passenger recreational facility,with daily whistle-stop service in the summer season and weekend whistle-stop service off-season. -While there will continue to be an international clientele for select facilities,the project will primarily be an in-state E-7-38 - -., i - ..- I I I r - -. I r 3.2 -Indirect Impacts recreational attraction and will not be a major national or international tourist attraction such as Denali National Park • -Because of climate,winter darkness,and distance from popula- tion centers,the project will be primarily a summer (mid-June to mid-September)recreational resource. 3.2.3 -Estimated Recreational Demand Available recreational studies were surveyed and evaluated for app1 icabil ity to the Susitna Hydroelectric Project.A wide variety of noncomparab1e and to some extent disparate data were found.A series of per capita participation projections devel- oped in the Susitna River Basin Cooperative Study -Talkeetna Subarea (U.S.Soil Conservation Service 1978)were chosen as the most appropriate methodology and assumptions for this recreation p1 an.That methodology and major portions of the base data/.7'\ employed in that projection are used and referred to as the "per\.6; capita participation method."The projections have been modified for purposes of this recreation plan by updated population data and projections.Allocations of regional recreational demand derived from these projections are assigned to the Susitna Hydro- electric Project recreation area through a series of assumptions and judgmental evaluations.The results of this estimation are then compared with four estimates,prepared by other methods,and identified for the purposes of this report as: -Willingness to drive comparison; -Denali National Park comparison; -Denali Highway travel comparison;and -Op in ion survey compa ri son. ~- (a)Per Capita Participation Method This method was developed by the U.S.Soil Conservation Service (SCS)and applied to the 13 million-acre (5.2 mil1ion-ha)Talkeetna Subarea in 1978 as part of a series of Susitna Ri'ver Basin cooperative studies which were joint efforts with the A1 aska Department of Natural Resources,the A1 aska Department of Fi sh and Game,and other cooperat i ng agencies.The method utilizes empirical participation rates for eight major outdoor recreational activities and applies them to existing population figures. The demand projection presented in this report uses the gen- eral methodology and recreational data developed by SCS. The actual calculations presented herein,however,were per- formed by the Susitna Recreation Plan Study-Team specific- ally for this study.The planning year 2000 was chosen for E-7-39 3.2 -Indirect Impacts convenience and cOl11parab"i 1ity as the future demand project time.Assumed percentage increases in annual participation days are utilized,as well as year 2000 population projec- tions.The following formula was utilized to estimate 1980 recreational demand: TOTAL 1980 POPULATION X AVERAGE ANNUAL PARTICIPATION DAYS TOTAL DEMAND IN USER DAYS To estimate 2000 recreational demand: TOTAL 2000 POPULATION X AVERAGE ANNUAL PARTICIPATION DAYS X ASSUMED PERCENTAGE INCREASE IN PARTICIPATION =TOTAL DAMAND IN USER DAYS This procedure is followed for each of eight separate acti- vities.Populations used are shown in Table E.7.7.Recrea- tional participation is shown in Table E.7.8. Both participation days and assumed increases are taken di- rectly from the 1970 Alaska Outdoor Recreation Plan.While more recent participation and preference data were published in the 1976 and 1981 Alaska Outdoor Recreation plans,aver- age annual participation days-per capita were not provided in those reports.While newer data,if available,would have been preferable,it is assumed that the projected in- creases in participation published in the 1970 plan are suf- ficiently representative for the purpose at hand.Compari- sons of the activity particiParrtiQR r.a...t.....es w.h.iCh appea...r in allthreeplanssupportthisassumion._---..----..

E-7-40 -I ..... i - ""'"' - .~ I - r-. i ,~ 3.2 -Indirect Impacts The centroid of the project recreational area is assumed to be 10 mil es (16 km)north of the Watana damsite,determi ned by observation.Table E.7.10 gives estimations of total recreational demand (in user days)for all recreational sites within 250 miles (415 km)(or 5-6 hour:s)of Anchorage and 200 mil es (330 km)(or 4-5 hours)of Fai rbanks for the popul at i on of Anchorage,Fa irbanks,and Matanuska-Su sitna Borough.It is important to note that these demands are for all sites within the given time-distance,not specifically for the Susitna hydro site.For instance,other sites with- in a 5-to 6-hour drive from Anchorage could include those south on the Kenai Peninsula or east in the Wrangell Moun- tains.Time-distance factors are based on empi rical evi- dence as developed by the SCS,whereby the number of trips in each hourly travel band is estimated as a proportion of the whol e.These estimates were cal cul ated separately for each type of recreational activity using the population given in Table E.7.7,the factors in Table E.7.10,and the distances i~T~E.7.9. Table E.7.1~ummarizes these demands.In order to apply total demands to the Su sitna Hyd roel ectri c Proj ect recrea- tion plan area,a number of additional assumptions were made. The project recreation plan area was generally defined as the area extending from the Parks Highway on the west,the Denali Highway-Nenana River on the north,the Susitna River on the east,and about 20 miles (33 km)south of the Susitna Ri ver on the south.Thi s area was determi ned by the areas direct ly affected by development,known recreat i onal re- sources of the area,and the recreational opportunity set- tings determined by the study team in the field.It also takes into consideration Alaska Department of Fish and Game management subunits.Since these units relate to big game management areas and not human recreation areas,the area studied 'does not correspond exactly to those boundari es. Correlations will be made for management purposes during Phase II design. Alaska Department of Fish and Game (1981)hunting statistics for moose,caribQu and Dall sheep were reviewed.These data i ndi cated that in 1981,fewer than 700 hunter days we re spent in the management within the study area.Only data for the hunting year 1981 were available for review.There- fore,in order to be conse'rvative,it was assumed that the existing condition is 800 hunter days.Table E.7.12 and Table E.7.13 show assumed existing (1980,for simplicity) use of the area in numbers of recreation days and in per- centages of the total days given in Table E.7.11. E-7-41 3.2 -Indirect Impacts It was assumed,based on observation and personal conversa- tions with informed local sources,that there are currently 100 waterfowl hunting days in the area.This activity is generally limited to the lakes along the east side of the Parks Highway,an area only peripherally connected with the project area in terms of recreation-setting identity. - Assumptions of current sport fishing were made from inter- pretations of the Alaska Department of Fish and Game State- wide Harvest Study (1981 data).This report lists angler days for 1977 through 1981.Data i ncl ude the number of anglers resident in the upper Copper/Susitna River area who fish in all locations.This number is decreasing from 1885 in 1977 to 1195 in 1981.Charts of the number of angler days fished in the West Cook Inlet/West Susitna drainage and the East Susitna drainage show that these figures have gen- erally decreased over the 1 ast four years.The 1 evel of fishing in this area as a percentage of statewide fishing has al so decreased by 2.5 percent in the 1 ast three years (see Appendix 7.C). While these data do not directly correspond to the project area,in combination with personal conversations with knowl- edgeable local sources the project team estimated 1500 angler days/year to be in the area.Fishing activity is assumed to be quite low in the areas because it is inacces- sible by auto and has no salmon runs except on the Susitna River below Portage Creek and on Prairie Creek. Number of user days was assumed to be 4000 at the only developed campsite in the area.The BLM camp at Brushkana Creek on the Denal i Hi ghway has 33 campsites and is report- edly at capacity during hunting seasons.The assumed cur- rent numbers represent a capacity use,with three persons per campsite,during a month-long hunting season.Two addi- t ional months of capacity use,with two persons per camp- site,were cal culated for the weekends of the other two summer recreation months. It is assumed that there is essentially no hiking or pic- nicking occurring in the 'area that is not associated with other activities such as hunting,fishing or camping.Hik- ing trails are not rigorously designed for specific capaci- ties at the primitive level of design anticipated,and pic- nicking in this remote area is most frequently associated with camping;therefore,this simplifying assumption is appropriate. E-7-42 ..", I -I 1 I ~ I ! -, - ,.... - 3.2 -Indirect Impacts Cross-country skiing is known to exist in the Chulitna Moun- tains south of Cantwell,and 100 user days have been assumed for the study area. As in:,lcated i Table E.7.13,it is calculated that approxi- matelY\,,6700 ecreation days per year occur in the area today.order to proj ect the future user days for the area if the Susitna Hydroelectric Project is not built,1980 to 2000 population growth rates (Table E.7.7)and increased participation rates (Table E.7.8)are applied to the 1980 usage.That is,usage in the year 2000 will increase as will population and propensity to recreate,given no other actions such as construction of access roads into the area. This simplification does not take into consideration the changing attraction val ues of other recreational opportun- ities in the'state.As other recreation areas are developed projected demand will be redistributed.It is assumed that this will cause a decrease of demand at Susitna and there- fore reinforce a conservative estimation. In the case of the future campi ng estimate at developed campgrounds,a different procedure was followed.While demand as cal culated above shows an increase to 9700 user days,it is typical for campground supply to lag behind demand for the unaccommodated increment to go to undeveloped sites.The BLM Denal i Block Management Plan (BLM 1980) call s for three 3-unit pull -offs in the a rea,and it is understood that an expansion of the Brushkana Campground is under consideration.Therefore,a doubling of developed campground space has been assumed for the year 2000. In summary,without the hydroelectric project,about 12,500 recreation days could occur in 2000.This is almost a 90 percent increase over 1980 figures. In order to estimate the year 2000 recreational demand, assuming the Susitna Hydroelectric Project is built,the baseline (without project)recreational growth rates shown in Table E.7.12 were examined and compared with project impacts as described in Section 2.In addition,the team's knowledge of the project area derived from a careful recrea- tional opportunities'assessment and study of regional al- ternative opportunities. For big game hunting,increased road access will lead to increased activity.The 1981 Geowonderlgod•...data base indi- cates that most hunters currently fly into the area.Be- cause the game resource is limited and regulated,a maximum increase of 0.2 percent is assumed.Today's capture rate is E-7-43 3.2 -Indirect Impacts 0.3 percent of total demand.The year 2000 is assumed to have a capture rate of 0.5 percent of total demand (see Tables E.7.12 and E.7.13.). No waterfowl hunting increase over baseline figures is anti- ci pated as no propos~d project features W"j 11 affect the attractiveness or accessibility of the waterfowl hunting 1 akes. Presently,freshwater fishing is very limited due to lack of automobile access.Most existing fishing sites are used principally by fly-in fishermen.It is assumed that this demand,like hunting,will increase 0.2 percent,attacting approximately double the number of fishermen as in the base case and triple the current use. Developed campground demand is a function of both the demand for other resources (e.g.,hunting and fishing)and the opportunities available to meet theoretical demand.Because of the wilderness nature of the area and the stated objec- tive of protecting the natu~a1 resources,demand is expected to be directed toward small,primitive campgrounds.Demand is anticipated to be limited to an additional 4000 to 6000 visitor days per year. After the Susitna project ;s completed,part of the river resource for canoeing and kayaking,and in particular the important Devil Canyon Rapids,will be eliminated.User days are estimated to decrease to half their 1980 levels. Demand for hiking and picnicking is anticipated to be equal to that for camping. Demand for cross-country skiing is assumed to increase about 50 percent over the base case due to increased accessibility and interest in the area. A total of about 43,500 to 50,200 vi s itor days pe r year are projected for post-project conditions in the year 2000.The recreation plan has been developed to accommodate this growth,phased to the Watana and Devil Canyon portions of the project.Other recreational uses,such as driving and sightseeing,are assumed to be included in this estimate. This appears to be a reasonable assumption because recrea- tional demand often takes 10 or more years to build up after facil iti es ar~developed and the curiosity val ue of the project is assumed to wane over time. E-7-44 - - - ....1 -I I - - 3.2 -Indirect Impacts - I r i I""" ! r ,.... I f""'" I i [ (b) (c) Willingness to Drive Comparison Cl ark and Johnson (1981)"j ndi cate that 20 percent of the population is willing to drive five hours to a waekend rec- reational area,and an additional 11 percent will drive six or more hours.Applyi ng these data to the projected year 2000 population (0.31 x 450,570),it can be estimated that approximately 140,000 persons from the Railbelt,Anchorage, and Fairbanks could be attracted to a site the distance of the study area in a single year.Assuming a capture rate of 33 percent,approximately 46,000 persons could be attracted to the Susitna.This estimate is in reasonable accord with that developed by the participation method. Denali National Park Comparison The entrance to Denali National Park is about 80 highway miles (130 km)from the Watana site.With Mt.McKinley, North America's largest mountain,the Park is a world- renowned recreati onal attracti on.In 1981,the area attracted 256,500 recreational visitors and has shown gen- erally a high rate of increase since the Parks Highway was opened "in 1971 (see Table E.7.14).While the National Park Service has not projected visitation to the year 2000,the Denal i State Park Visitor Facility Market Analysis and Eco- nomic Feasibility Study (Economics Research Associates, 1980)projects total recreational visitors to Alaska to increase from about 550,000 in 1982 to 1,100,000 in 2000 (high range).If Denali National Park increases at the same rate as the state as a whole,visitation in the year 2000 would be approximately 513,000. - - ,..,., The recreational attraction of the Susitna project has a very different character and appeal than Denal i National Park and offers only a small portion of the attractions. Today,the area appears to draw about 2.5 percent of the number of vfsitors drawn to the national park.·If,after project development it were to draw,for example,10 percent of the visitation of the national park,thatwould be 51,000 in the year 2000.This calculation is also similar to ~-". estimated in the per capita participation method.~ (d)Denali Highway Travel Comparison Because the primary access to the Susitna recreation area wi 11 be via the Denali Hi ghway ,comparisons can be made up to existing and future recreational traffic volumes along the highway.Results from a recreational study for the Denali Highway area (Johnson 1976)indicate that 90 percent E-7-45 3.2 -Indirect Impacts of the highway travelers were recreationists and that aver- age vehicle occupancy was 3.2 persons.The Environmental Assessment for the Denali Highway (Alaska Department of Transportation 1981)reports existing average dai ly traffic (ADT)on the midsections of the highway as 50 vehicle trips per day.The study projects this to rise to 130 by the year 2000.130 trips/day x 3.2 persons/vehicle x 365 days/year x 0.90 recreation =135,656 recreation trips per year. Assuming the Susitna area captures 33 percent of these trips (as in Comparison [bJ),a total recreational demand of 45,100 trips could be anticipated.This method also has results similar to the other projections. (e)Recreation Participation Survey Method The University of Alaska and TES,Inc.,conducted recreation participation surveys as a part of their early studies.The surveys were intended to determine the existing level of use within the study area (TES 1982a).The survey was mailed to a random sample of 3116 Railbelt residents.Six-hundred and three of these were returned resulting in a response rate of 23 percent.Of those who responded,148 individuals or 25 percent stated that they currently use the study area for recreational purposes.By simple extrapolation,25 percent of the 1980 Railbelt population which is 284,166 places the number at 65,973 persons who could presently recreate in the area.If,however,nonresponse to the questionnai re was assumed to be a no-use response,as few as 14,339 persons' were consi dered to recreate there by the authors of that study. Based on detailed knowledge of activities in the study area, it seems highly unlikely that this many people recreate in the study area (see Tab le E.7.13).It appears that the responses were skewed by "yes II rep 1i es from persons who do recreate there and who responded in higher overall propor- tion than their proportion in the population.Additional error may have been introduced through the survey illustra- tions which include portions of the Parks and Denali high- ways in the study area.However,even taking the average value of these two figures (40,156),and projecting it at the growth rate of 55 percent (the rate of population growth),62,200 would recreate in the area by the year 2000. The estimates of future use generated in that study are based on questions regarding anticipated future use of the project.They are not considered reliable due to changes in E-7-46 - - - - - -3.2 -Indirect Impacts the project features since the survey was conducted.The generally unreliable nature of asking people how they would like to recreate rather than how they actually recreate also contributed to this unreliability. (f)Conclusion Using the method (the per capita participation)project demand for recreation is estimated to be 43,520 -50,220 user days/year.In comparison,other estimates are: Comparison Compari son Compa ri son Compa ri son (b): (c): (d): (e): 46,000 51,000 45,100 62,200 Based on the assumptions set forth in this section and the variable predictability of recreational estimates for the Susitna Hydroel ectri c Project,project demand will be considered to be: 43,000 -50,000 r~creation user days/year at the completion of the project in 2002. These are proportioned as shown in Table E.7.13 and summarized as follows: - .- Acti vity Big Game Hunting Waterfowl Hunting Freshwater Fishing Developed Camping Canoeing/Kayaking H"iking Pi cni ck i ng Cross-count ry Ski i ng E-7-47 Annual Visitor Days 2,200 -2,400 170 4,800 -5,200 12,000 -14,000 100 12,000 -14,000 12,000 -14,000 350 - - ~ I ~ I - - ,f/OfDo - - 4 -FACTORS INFLUENCING THE RECREATION PLAN The approach utilized in this study recognizes six major factors that influence the ultimate design of the recreation plan.They are: -Construction access and phasing; -Operationa)characteristics of the project; -Recreational use patterns and demand; Management obj ect i ves of the interested agenci es and Native corporations; -Facilities'design standards;and -Financial obligation and responsibility of the Power Authority. These factors were analyzed then uti 1i zed to set parameters for the plan determination process.The first two factors above were described in Section 1.4.The third factor was discussed in Section 3.2.The remaining three factors are discussed below. 4.1 -Management Objectives In addition to the Alaska Power Authority,various federal and state agencies and several Native corporations established under provisions of the Alaska Native Claims Settlement Act (ANCSA)have interests in this plan. 4.1.1 -Alaska Power Authority At this time no specific official statement of recreation policy has been developed by the Authority.The following policy state- ment regarding fish and wildlife aspects of the project was issued by the Power Authority in January 1982. "A mandate of the Al aska Power Authority charter is to develop supplies of electrical energy to· meet the present and future needs of the State of Alaska.Alaska Power Authority also recog- nizes the value of our natural resources and accepts .the responsibility of ensuring that the development of any new projects is as compatible as possible with the fish and wildlife resources of the state and that the overall effects of any such projects will be beneficial to the state as a whole. E-7-49 4.1 -Management Objectives -If development of the hydroelectric potential of the Susitna River proceeds,it is the Power Authority I s goal,and its intent to achieve no net loss in fish and wildlife productivity; -In achieving no net loss,mitigation measures that avoid or minimize impacts on existing habi- tat,all else being equal,are preferred over other types of measures; -The base line for assessing post-project impacts and the effectiveness of mitigation measures or enhancement opportunities,is the existing con- dition; -The Power Authority will work cooperatively with any responsible entity to explore ways the Susitna Project can complement the fish or wild- 1 ife enhancement plans of these entities; -The feasibility report will present previously. identi fied enhancement plans for the Upper Susitna River Basin and assess the Susitna Project's impact on the ability to realize those pl ans;and -The feas i bil ity report wi 11 present,as the pro- posed plan of development,a project configura- tion that maximizes power benefits.Concur- rently,all reasonable mitigation measures,in- cluding the maintenance of sufficient river flows to avoid appreciable impact,will ~be iden- tified,and their effectiveness and costs will be estimated.II To the extent that fish and wildlife resources constitute a part of the recreational experience,the general intent of this policy can apply to recreation also. In addHion,the following recreation-specific objectives have been identified by the study team: -The plan should attempt to meet the demands of project-induced recreation with facilities appropriate to the Alaska wilderness setting; -The plan should respond to the identified site opportunities and constraints; E-7-50 - """" -I - - ~, - - - - 4.1 -Management Objectives -The plan should make use of roads,materials and facilities developed during construction or already existing.This will require coordination with the construction plan and schedule. Such construction roads and facilities should,wherever pos- sible,be designed to conform with final recreational require- ments; -The plan shall be compatible with acceptable public safety and environmental health requirements; Recreation should be designed and operated in such a manner so not to create unreasonable demands on construction operation, resources for the project,or other public services; -Vari ous combi nat ions of owne rshi p and management by the state or by Native corporations may be appropriate for particular elements of the plan; -Irreversible losses will be identified and reasonable mitiga- tion and/or compensation will be provided whenever possible; -An area-wide systems approach should be taken in programming recreational activities and facilities which complements exist- ing regional facilities and provides a balance of recreational opportunity. 4.1.2 -Alaska Division of Parks The following statewide goals are stated in the Divisionis Alaska Outdoor Recreation Plan (1981): -Provide for and enhance Alaska's outdoor recrea- tion land base to meet the needs of present and future generations of Alaskans and visitors to the state; -Establ ish state and local recreation programs and respond to a diversity of outdoor recrea- tional needs as expressed through an assessment process and based on full public participation; -Integrate outdoor recreational values and diver- sity of recreational opportunities and programs into coordi nated interagency prog rams,commun ity programs,and private sector developments; -Promote and balance the development of outdoor recreational opportunities in proximity to or within urban and rural communities; E-7-51 4.1 -Management Objectives -Recognize and provide for the needs of special populations; Strengthen the capabil ities of publ ic agencies to establish,operate and maintain outdoor rec- reation programs through technical and financial assistance programs; -Support the development and expansion of tourism in Alaska and its role in outdoor recreation; -Preserve,maintain,or enhance Alaska1s scenic resources,environmental qual ity,natural areas and cultural and historic identity;and -Foster the growth and development of a strong, central role of the state in meeting outdoor recreational needs through a system of park and recreational units and historic and recreational trails and waterways. In addition,discussions with the Division of Parks staff have suggested preferences for the following recreation character- istics specific to the Susitna project: -Selected sites should be intrinsically suitable and the best sites available for recreation,not merely areas available by virtue of project development; -The Susitna project recreation plan should become an integral, logical extension of an overall state recreational network; Construction and operations costs will require contributions by the Power Authority;and The Division welcomes participation in the provlslon of recrea- tional opportunities in the state by private entities such as the Native corporations. The Alaska State Parks System South-central Region Plan (ADNR, Division of Parks 1982a)identifies one proposed acquisition which coul d infl uence the Susitna project recreation pl an:The Talkeetna State Recreation River.This proposal would entail legislative designation of ,the river corridor,preparation of a river management plan,and subsequent development in conformance with that plan.The Talkeetna River is presently reached via portage from the Susitna River to Stephan Lake and Prairie Creek by river recreationists originating on the Susitna,Tyone or Lake Louise areas or by flights directly to Lake Stephan.Current division thought is that the objectives of this plan may be met E-7-52 - - - - !J!!!'): -I - ..... - ~ I 4.1 -Management Ojectives without actual legislative designation.Portions of this area have also been selected for conveyance to the CIRI Village Corporations,including Stephan Lake,Prairie Creek,and the upper reaches of the Talkeetna River. 4.1.3 -Alaska Department of Fish and Game As a part of the Fish and Wildlife Mitigation Review Group,the Al aska Department of Fi sh and Game participated in the develop- ment of the "Susitna Hydroelectric Project Fish and Wildlife Mitigation Policy"published by the Alaska Power Authority.This policy states that it is the basic intent of the Power Authority "to mitigate the negative impacts of the Susitna project on the fish and wildlife resources." While the Department of Fi sh and Game has not issued a specific formal statement of objectives regarding project-rel ated recrea- tion,discussions involving the recreation team and Department staff have suggested the following objectives: -Protect from over-fishing the trophy-class grayling population in Deadman Creek; -Protect from highway traffic dangers the Nelchina caribou herd; -Maintain important fishing resources downstream from Devil Canyon; -Protect back country from unregulated access along construction of other project-related roads;and -Regulate hunting and fishing activities of the construction force. 4.1.4 -U.S.Bureau of Land Management The Bureau of Land Management (BLM)is manager of substantial federal land holdings generally north of the Susitna River and along the Denal i Highway.Statements of BLM objectives are found in the agency·s BLM Land Use Plan for South-central Alaska:A Summary (1980).This plan acknowledges development of the Susitna project and the access corridor from the Denal i Hi ghway which can serve to:ufacil itate publ ic access to the back country."Specific policy statements which can relate to devel- opment of the recreation pl an for the Susitna Hydroelectric Project include: -Develop a water trail on the Maclaren River downstream from the Denali Highway crossing to the Susitna River and up the Tyone River to Lake Loui se; E-7-53 4.1 -Management Objectives -Rehabilitate the Brushkana Campground on the Denali Highway; -Develop a series of "three-unit wayside camping areas ll along the Denal i Highway.Seven are indicated,incl uding three between Cantwell and the Susitna River; -Develop interpretive signs,etc.along the Denal i Highway to explain natural history and archeology; -Protect the shelter cabins built along the Cantwell-Valdez Creek Trail by the Alaska Road Commission during the 1920s. (Three are identified near the juncture of the project access road and the Denali Highway); -Protect caribou migration routes from adverse effects of human activ ity; -Create protective buffer stri ps around 1akes and water bodies used by waterfowl; -Protect from fire the portions of the caribou range that have a strong lichen component; -Protect Dall sheep winter range and 1 arnbing areas from all activities not consistent with maintaining the population; -Identify and protect salmon spawning areas;and -Allow saddle and pack horse grazing in the Brushkana Creek- Denal i Highway and the Susitna River-Denal i Highway areas upon lease appl kation and determination of carrying capacity,in order to benefit local guides. Two off-road vehicle (ORV)study areas are designated "in the project vicinity comprising most of the BLM lands between the Susitna River and the Denal i Highway.These areas are presently open to ORV use,as are all BLM lands in the area,except Tangle Lakes.The clear-water drainage has been closed by the State Fish and Game Commission to mechanized hunting.In addition, recent federal action has opened major portions of the Denal i Block to mineral exploration and mining entry,which could be in conflict with recreation and wildlife objectives.The Denali Highway is currently under study for possible designation as a scenic highway.Mining access has been withdrawn within one mil e of the hi g hway for thi s reason.If the hi g hway receives scen ic designation,it is likely that the temporary project electric transmission line as well as any borrow pits would have to be located out of sight of highway traffic. E-7-54 - - -i I"'"' i 4.1 -Management Objectives 4.1.5 -Cook Inlet Region Inc.and Village Corporations Land ownership patterns in Alaska are unique and will have signi- fi cant impacts on the recreation plan.Pri or to statehood in 1959~most lands in the project area were owned by the federal government and managed by BLM.With statehood~Alaska was allowed to select lands from federal holdings for patenting to' the state.When ANCSA was passed in 1971~this process of land transfer to the State was incomplete.Within the Susitna project vicinity~some lands had been selected by the state and patented to the state;other lands~while selected by the state~were not yet patented to the state.Under terms of ANCSA~further action on these lands has been suspended in favor of Native lands selec- tion.These lands are identified as state selection suspended on project land status maps. ANCSA provides land and money as compensation for the aboriginal land rights of Alaska Natives and established corporations re- sponsible for managing these assets for the benefit of Nati ve shareholders.CIRI is one of the 13 regional corporations estab- lished by the Act and has received portions of both its monetary and land entitlements under conditions of the Act.Portions of these entitlements are in turn to be reconveyed to village cor- porations that are currently in the process of selecting 1 ands from the region's master selection.Villages also have their own entitlements not related to CIRI selections.Major portions of the Susitna project area have been selected by CIRI.Portions of that area will be reconveyed to CIR I vill age corporat ions.When the process of reconveyance and patenting is complete~the vil- lage corporations will own surface estate to significant portions of the lands;CIRI will own subsurface estate to those lands and also surface and subsurface estate to the lands in their master selection .which the villages did not select for themselves. These lands will be private ownership~not public.Twenty years from the date of conveyance~they will be subject to property tax assessments. Discussions with the village corporations and CIRI have led to the following understanding of their objectives: -CIRI will defer to the village corporations regarding the development of recreational facilities; Project land ownership of the reservoirs should be confirmed to the high-water line~giving the Native corporations maximum flexibility for later private development; Native corporations must find and develop economic uses of their lands~including recreational uses~to meet future tax 1iabil ities; E-7-55 4.1 -Management Objectives -Native corporations want to actively participate in the recrea- tional planning,decision-making,and management process; -They do not necessarily want to lose land ownership in order to provide public recreation; -Publ ic use must be carefully managed to avoid over-use and en- vironmental degradation; -Trespass must be regulated; -The state must assume liability responsiblity for any project- related recreational use of Native lands;and -The Native corporations would benefit from provision of tech- nical recreational planning assistance subsidized by the Power Authority. The Native corporat ion s have expressed wi 11 ingness to parti ci pate in a cooperative recreational planning process to assure provis- ion of recreational opportunities while meeting Native objec- tives.Possibilities under discussion include but are not limited to: -Ownership of recreation areas by the Native corporations and lease to the state; -Ownership and management of recreation areas by the Native cor- porations; -Ownership by the Natives and joint management by them and the state under Sec.907,Al aska Land Bank,of PL 96-487,the Al aska National Interest Lands Conservation Act; -Purchase of lands by the state,but facility management by the Natives under a preferred concessionaire or similar agreement; and -Lease by the state of 1 ands for project construction camp facilities and reuse by the Natives for recreational use. 4.1.6 -Matanuska-Susitna Borough The project area is located -in the Talkeetna Mountains Special Use District of Matanuska-Susitna Borough.As such,any develop- ment is subj ect to a permi t from the boroug h. The Matanuska-Susitna Borough Coastal Management Program (WCC 1982)includes the Susitna River up to Devil Canyon where the E-7-56 - - - - ..... - - ..... - 4.3 -Financial Obligations and Responsibility River south of the study area.The Devil Canyon damsite is des- ignated as a "po tential"Area Meriting Special Attention (AMSA) in that document.Under Alaska statute,should the area be des- i gnated an AMSA,a proposed management scheme woul d have to be developed by the borough and appropriate state agencies. In 1982,the borough also published a draft Trails System report designed to identify trails that ought to be preserved or estab- lished in the borough.None are identified in the immediate vicinity of the project area.The borough does not manage any recreation areas,but rather participated in joint planning with the State Department of Natural Resources.In some instances, they have provided lands and monies to the state for park devel- opment. 4.1.7 -Alaska Department of Transportation The Alaska Department of Transportation (DOT)utilizes the Arneri can Associ ati on of State Hi ghway Offi ci al s (AAS.HO)Geometri c Design Guide for Local Roads and Streets (1970)as design stan- dards for rural roads such as the project roads.Average Daily Traffic (ADT)design year is 20 years from the present. The Alaska Department of Transportation and Public Facilities is currently proposi ng the upgrade the Denali Hi ghway between the Ri chardson and the George Parks hi ghways.A need for improve- ments has been identified on the basis of a traveler survey, numerous interviews,and predicted future traffic.Upgrading 134 miles of roadway will correct roadway structure deterioration and substandard elements and will accommodate recreational use demand along the highway according to the Denal i Highway Envi ronmental Assessment (1981).Proposed project activities include minor road realignment and widening,paving and pavement repair,bridge and cul vert repl acement,and turnout and stream access improve- ments.No relocation was considered necessary in the Denali Highway Location Study Report (1981). 4.2 -Facilities·Design Standards State of Alaska,Division of St~te Parks design standards will be used for the proposed recreational facilities.This is intended'to minimize operational,managerial,and mai ntenance costs of the facilit ies for state park management. 4.3 -Financial Obligations and Responsibility of the Alaska Power Authority Alaska Power Authority,as a state agency,has stated that it will pro- vide for the public interest and implement an appropriate recreation' E-7-57 4.3 -Financial Obligations and Responsibility ~lan.The ultimate responsibility and obligation for development,.~perat i on and mai ntenance of the recreational facil it i es rel at i ve to he project rests with the Power Authority.Financial commitment is related to numerous tradeoffs to be made by the Authority in terms of satisfying,with 1 imited resources,the needs of many concerned user groups.The Al aska Department of Natural Resources expects the Power Authority to be responsible for meeting initial and future project- related recreational needs for the duration of the project license. The extent and nature of the responsibility will necessarily be depen- dent upon the conditions of the FERC 1i cense.In the event that the recreational needs IIJithin the project area should change or other specific needs not outlined in this Exhibit are identified,periodic reviews,as outlined in Section 6.2,will provide an opportunity to make adjustments to the pl an.The responsibil ity for project fi nanc- ing,development,and operation will be negotiated betwen the parties concerned at the time the adjustments are needed and are subject to FERC approval. E-7-58 - - - - - - - """"I - - 5 -RECREATION PLAN 5.1 -Recreation Concept 5.1.1 -The Concept The intent of this recreation plan is to satisfy the recreational demands created by hydroelectric development and to accommodate public use of the project areas.The plan offers compensation for recreational opportunities lost as a result of development. It does not attempt to duplicate exactly or replace these oppor- tunities.The plan is also intended to fit with,in the framework of regional recreational opportunities and to provide additional options.It accommodates these diverse recreational concerns in a manner which fits the inherent opportunities and constraints of the study area landscape and protects its scenic~cultural~and environmental qualities. The Susitna study area is rich in special large-and small-scale landscape settings and features~and has great potential for a wide variety of recreational uses.The area includes wooded stream valleys and gorges~tundra and muskeg landscapes~and mountainous glaciated terrain filled with lakes~bogs~water- falls~glacial~and many other special features.These land- scapes are comprised of a wide variety of plant communities and wildlife inhabitants. The recreation concept was developed after a careful eval uat i on of the recreational opportunities and constrai nts within the study area~regional recreational concerns~and estimated demands.It utilizes information gained from earlier public par- ticipation programs. The concept provides for a challenging variety of activities and experiences within a developmental range of natural wilderness to semiprimitive recreational facilities.Road access has been limited.Other options such as airplane~boat~train~and foot access are available to a variety of recreation areas.Off-road vehicular use will continue in existing BLM areas. (a)'Major Considerations of the Recreation Concept (i)Regional Approach Ihe Susitna project is exceptional in its large scale and suggests a regional approach to the recreation plan.The study area is extended beyond the immedi- ate perimeter of the reservoi r sites in order to thoroughly examine all adjacent landscapes and satisfy demonstrated recreational need. E-7-59 5.1 -Recreation Concept (ii)Fluctuating Reservoir Water Levels The greatly fluctuating water level of the reservoirs precludes the use of the reservoi redge and any buffer zone from recreational use. (iii)Hiking Trails In response to the projected recreational needs of the state,since the number one recreational priority is hiking trails,a principal objective of this rec- reation plan will be to help meet this priority in appropriate portions of the project area. (iv)Educational Values To take advantage of the great recreational value of understanding the Al askan envi ronment,a variety of opportunities will be created to participate in and view the 1 andscape ina range of scales.Thi s variety will also represent and accommodate a variety of users. (v)Public Interest in Hydroelectric Facilities To accommodate the great interest of the publ ic to observe and understand the hydroelectric facilities themselves,that development focuses activity on a core of recreational facilities and diverts'the greatest number of users away from sensi t i ve opera- tions or environmental areas.Hydroelectric facil- ities which have appeal as a recreational resource have been incorporated into this concept. (vi)Recreational Needs of Temporary Construction Workers and Permanent Village Residents The concept also considers the complex recreational needs uf the temporary construction camp workers and ultimately the residents'permanent village.At these locations the concept is intended to provide a variety of highly developed recreational facilities, both indoor and outdoor,whi ch will sat i sfy demands without overtaxing the area's limited primitive rec- reational capacity. The recreation concept was formulated to take advantage of these opportunities and the best natural features of the Susitna Basin rather than restricting the evaluation to specific project E-7-60 - - - ~ I i I!Ii!llj I i - - 5.1 -Recreation Concept facilities.In fact,after analysis,the highest quality recrea- tional opportunities were found to be in the diverse landscapes adjacent to the reservoir sites and not at the reservoirs them- sel ves.Because of thi s fact,there are not many recreational facil ities within the buffer zone which could potentially be impacted by changes in the dynamic edges of the reservoirs. 5.1.2 -Public.Input During earl ier studies of recreational needs for the Susitna project,the University of Alaska dist~d a Concept Plan Sur- vey to the public in order to solicip·trb~m ..to the rec- reational planning process.The uestionnaires rtaining to public preferences for activities a development,as well as their perceptions of recreational potential in the proj- ect area,were mailed to potential users in Anchorage,Fairbanks, and other areas of the Rail belt.An abbreviated form was also used at public workshops to gain additional information regarding publ ic interests and desi res regarding recreational development. The survey and its results were published in The Recreation Plan for the Susitna Hydroelectric Project (University of Alaska 1982).Early concept 131 ans .incorporated into these question- na"ires do not reflect later engineering and schedule planning decisions and project modifications;however,those survey por- tions which identify public recreation opportunity spectrum pref- erences continue to be valid.These identified preferences serve as the framework of the proposed recreation plan. A total of 2145 surveys were distributed.Recipients were given a choice of five alternative approaches to development and asked to rank the five in order of value.The choices were: Approach A -Minimally developed and managed wilderness with no access; Approach B -Managed wilderness with limited access; Approach C -Watana Dam development; Approach D -Devil Canyon reservoir development;and Approach E -Highly developed and managed throughout. Results of the 549 responses were separately analyzed by region (Anchorage,Fai rbanks,and other areas of the rai 1belt)and by residence classification (urban,rural,remote rural,and other) but no significant statistical differences were found.Approach B was found to have the highest overall value to the respondents. Therefore,the recreation concept is based on minimal and E-7-61 5.1 -Recreation Concept primitive development having only limited access within a managed wilderness area.Further analysis of the attached comments indi- cated that facilities should be developed and managed on an as-needed basis,starting with minimal services and expanding only as demand warrants.This preference has been reflected in the proposed phased implementation program. 5.2 -Recreation Opportunity-Inventory 5.2.1 -Methodology The procedure for the inventory of the land base and the analysis of the intrinsic recreation potential of the sites was as foll ows: -Reviewed all planimetric information,USGS quadrangles,pre- vi ous i nventori es and aeri al photographs. -Located the occurrence of all attractive features as understood from above,and including local knowledge and previous work, e.g.,the recreation plan published (TES 1982d). -Field checked all sited located in the previous step p1us new potential sites,using the inventory shown in Appendix 7.B. Defi ned the qual ity and extent of the various 1andscape fea- tu res. -Mapped all features and settings depicting the distribution and location of the recreational resources.Included are indica- tions of special or significant views and vistas (see Figure E.7.5.Recreational opportunities,hunting,fishing,and col- lecting sites are not specifically located or symbolized.The opportunity exists to experience the wildlife in many ways as they naturally inhabit the entire landscape. 5.2.2 -Inventory The aim of site inventory is to inventory the land base of those landscapes which support the most diverse range of possibilities. It includes three steps to define recreational resources inherent to the site: -Attractiveness (physica1 description); -Recreation preference type;and -Accessibility.. (a)Attractiveness Attractiveness is a measure of a landscape's unique or special settings and features.These can be both cultural E-7-62 ~ i r- I .... .... .... - .... r -! 5.2 -Recreation Opportunity -Inventory and natural.However,they are almost exclusively natural within this study area.The 1 andscape was inventoried for features (thei r frequency and signi ficance)which bear on the potential for recreation.The natural features and thei r typi ca 1 characteri st i cs whi ch were determi ned to be important in the study area are as follows: -Mountaintops:rocky,craggy,often snow-capped,usually above timperline,glaciated or glacier forms most unique and impressive; -Tundra landscapes:tundra landscapes,both wet and dry, with close-up beauty and photographic resources; -Lakes:naturally occurri ng,degree of enclosure,habitat,· formation,glaciated lakes and beaver ponds most unique; -Rivers:glaciated,ruggedness and enclosure,quality expressive of Alaska,size,edges; -Streams:character,clarity,size,edge; -Water features:waterfalls,cascades,beaver ponds,snow- fields,ice; -Hunting habitats:locations of big game animals and birds; Fishing habitats:location of fish species; -Botanical interest sites:unusual plants,or systems; and Special aesthetic features:unique exploratory vistas, features and settings • (b)Recreation Preference Type .A principal objective of the recreation plan is to provide a variety of recreational activities within ,a spectrum of rec- reation "preference types"(USDA Recreation Opportunity In- ventory and Evaluation 1974).The preference types relate to the character and quality of the existing land base.The recreational activities also ~elate in terms of their appro- priateness to a particular setting.Patterned after the USFS Recreation Opportunity Spectrum (ROS)approach,the four recreation preference types used in this report are: E-7-63 5.2 -Recreation Opportunity -Inventory (i)Pristine A natural,unmodified environment,a source of intel- lectual or physical challenge;seeking solitude;aes- thetic stimulation.The landscape setting should be remote,devoid of people,with a stimulating natural environment and difficult to access. (ii)-Primitive A natural environment,a source of enjoyment of set- tings which provide fish or game species,rocks, edible plants,etc.The landscape setting should be natural,removed from human influences. (iii)Semi primitive Lightly developed locations,natural surroundings,a source of relaxation.The appropriate physical set- tings are natural-semiprimitive sites,'with rela- tively easy access. (iv)Developed I~an-made developed sites,with easy access.The a ppropri ate settings are developments which embody many people and site-specific interests. Recreation opportunity activities have been identified in relationship to the above reference types as follows: Pristine:Mountaineering,kayak-canoeing,backpacking,hik- ing,snow-shoeing,ski touring,.nature study,and photo- graphy; Primitive:Backpacking,hiking,photography,nature study, big game hunting,fishing,rock hounding,berry picking,and plant gathering; Semi primitive:Car camping,pleasure driving,boating, lodges,snowmobiling,hiking/waHing,and picnicking;and Developed:Sports,snowmobiling,tours,picnicking,and pleasure driving. Another major consideration is accessibility.The study area is very remote and must be considered as such in evalu- ating demand.A related consideration is the competition for the recreational user within the same framework for E-7-64 - ~ i. - - - - - 5.3 -Recreation Opportunity -Evaluation "remoteness"from such places as Denali National Park,the Wrangell Mountains,the Chugach Mountains,the Alaska Range, and the Kenai Peninsula. (c)Access i bil ity - - ..... Accessibility refers to the kind of roads,four-wheel-drive trails,foot trails,etc.,which are in or surround the study area.Access to the landscape occurs in four modes: foot,auto-ORV,boat,and plane.After the Susitna project is constructed,the damsite access roads will allow access to new areas by the auto-rel ated recreati oni st which were before inaccessible except by less convenient modes.Appro- priate access to the various settings is important in main- taining the setting preferences,e.g.,pristine activity preferences need to be difficult to access.This relation- ship is determined during the onsite field review. 5.3 -Recreation Opportunity Evaluation The major considerations for the evaluation of the recreation resources are: -Natural val ue; -Inherent durability; Visual quality; -Carrying capacity;and -Present 1and status. 5.3.1 -Natural Value Natural value is a measure of the inventoried landscape features and settings bas.ed upon the frequency of occurrence and overall quality. Natural value also defines the physical characteristic·s rela- tionship to the regional and local scales.The sites were evalu- ated on an onsite basis in a three-level rating: -High:value local or state resources,symbolic of Alaska land- scapes or carrying unique recreation potential--0.8 recreation opportunity quality factor (a factor defining the potential for attracting recreation users to a particular site); -Medium:moderately uncommon,expressive of local characteris- tic landscapes,exposure to abundant recreational resources-- 0.5 recreation opportunity quality factor;and -Low:commonly occurring landscapes with few features with rec- reation potential--O.2 recreation opportunity quality factor. E-7-65 5.3 -Recreation Opportunity -Evaluation 5.3.2 -Inherent Durability Durability is a general measure of the physical ability of a site to absorb the impact of recreational development.The evaluation is based upon known physical data and fi e 1d observat i on of each recreational resource site.There are four aspects to determin- ing durability for each site as described in the following matrix: Visual quality is a measure of the scenic quality and importance of the site •.The relative availability of significant landscape features and settings contained in each potential recreation site can be measured by: -Uniqueness based upon frequency and scale; -Levels of quality of the resource;and Imageability (reinforcing the Alaska landscape image)and visual quality of each setting. Unique settings and features are important to describe in terms of thei r qual ity and imageabil ity,and are related as indicated in the following matrix: - - Few extraordinary featu res with high apparency Uni que Alaskan Landscapes Hi gh E-7-66 Rare or Unusual .Landscapes Hi gh Common or Extensive Landscapes t-'edium ~ , - 5.3 -Recreation Opportunity -Evaluation Unique Alaskan Landscapes Ra re or Unusual Landscapes Common or Extensive Landscapes I""'" I I Several special features and settings Hi gh Med i um Low Encroachment and created landscapes Medi um Med i um Low 5.3.4 -Carrying Capacity -- Carryi ng capacity is the inherent capabil ity of a 1andscape to support recreation use.The primary purpose is to achieve fit- ness between the number of people using a site and the preferred recreation type (experience).The goal is not to reduce the ex- periential potential of site through over-use or participation. The United States Forest Service approach (U.S.Department of' Agriculture 1974)has been used in a modified version to define the carrying capacity of each. (a)Visitation Estimates visita- tion capacityrecreationsiteacres This method utilized two visitation estimates for each rec- reation site:(1)yearly visitation capacity;and (2) yearly visitation potential.Visitation capacity is an estimate of how many visitors can annually experience and use a particular recreational setting,based upon the desig- nated recreati on preference type.Thi s est imate is des- cribed by the following formula:' ~peak ~apacitY][dayS in][%?f.yeaJ[visitor.dayj*estlmate year utlllzed converSlon = .'factor Vi sitation potenti al estimates the probable actual use of the same recreational setting.This estimate is described by the following formula: ,.,... visitation capacity recreatio"opportunity * qual ity factor visitation potential Recreation opportunity qual ity factor is based upon the natural value of the recreation site. - *Constant (U.S.Department of Agriculture 1974). E-7-67 5.4 -The Recreation Plan (b)Peak Capacity Estimates Integral to these two formulas is the peak capacity esti- mates (PCE)of visitor use.The major criteria for these estimates are:(I)acreage of recreation settings;(2) encounter space (that area in acres of physical and visual potential for encounter);and (3)miles of trails and roads.Groups at one time (GAOT)is the unit for describing visitor groups (4 persons).For each recreation preference type various formul as were used to generate the estimated PCE as follows: [recreat ion l [%acres l** Pristine:setting acre~encounter spacd =PCE (250 acres/visitor group) r recreati on l[%acres l** Primitive:~etting acre~encounter spacd =PCE (100 acres/visitor group) Semiprimitive:(GAOT/mi trail )(mi trail)+(GAOT/mi 4WD road)(mi 4WD road)+(GAOT/mi 2WD road)(mi 2WD road)=PCE Developed:(GAOT/mi 2WD road)(mi 2WD road)+(GAOT/mi MTR) (mi MTR)+(GAOT of existing recreation facilities)=PCE These estimated capacities can be compared to the estimated recreation demand to verify satisfaction of estimated rec- reat i on need s. 5.4 -The Recreation Plan The Susitna Hydroelectric Project recreation plan includes the follow- ing sites and proposed facilities.Figure E.7.6 indicates extensive facilities such as long trails,and locates site-specific recreational facil ities.All sites are shown with a key 1 etter and phase number relating to text and maps.There are eleven additional maps which depict important features of the individual recreation sites (Figures E.7.7 -E.7.17). **Encounter space along trails is 0.5 miles wide.

All such elements planned for Susitna should be designed in Phase II so that the option is available either to incorpo- rate them into the recreation plan or to restrict pUblic access after construction to protect sensitive areas. These areas should be considered for development upon the completion of the 4-phased,site-specific facil ity program. These recreation opportunities woul d be part of Phase Fi ve in the recreation plan,to be developed only as need requi res • E-7-95 5.4 -The Recreation Plan It is of utmost importance in these cases to rehab il itate the disturbed environment (see Chapter 8,Aesthetics)and to allow a recovery period prior to future recreation devel- opllent.It is necessary to recreate the physi og raphi c character and indigenous plant communities as closely as possible and create new recreation opportunities,e.g., fisheries of native species,plant materials for gathering, etc. 5.4.6 -Recreation Plan for Construction Camps and Permanent Townsite (a)Background Because of its remote location,sequential development of construction camps at both the Watana and Devil Canyon sites has been planned.Each will be occupied for approxi- mately 8 years by at 1east a part of the work force.The peak n umber of wo rkers will be t here for 1ess than the entire construction period,and average work force will approximate half of the peaks.Therefore,facilities can generally be programmed to provide fewer opportunities both in rang e and extent than those in permanent communities. Prospective workers will understand that the project entails hardship circumstances and will not expect all the amenities of urban 1 ife.Experience has shown that there will be a turnover of work force through attrition.This means that, while a particular job may last the life of the project,it will not necessarily be filled by the same person for the entire period. Operation of the camps and the length of work days and work weeks will infl uence both the proportion of the work force who chose to 1 ive in camp compared to those who chose to live elsewhere (if that option is given)and the amounts and types of recreation required.In addition,climatic consid- eration will require seasonal adjustments.The largest work force will be active from April through October,and a mini- mum work force of 30 percent of that year's peak will con- tinue through December and January.The work pattern is planned to be four weeks.on and one week off.There will be two lO-hour shifts per day,seven days per week. While some Watana workers may choose to live in Cantwell or elsewhere,it is assumed that the majority will 1 ive at the camp and commute to their families'places of residence only periodically. E-7-96 - "'"'I I I- -I I I - - -. '""" - 5.4 -The Recreation Plan This recreation plan is intended to meet the needs of con- struction workers in residence at the construction camps;it is not intended to address the recreational needs of workers while not at the site. (b)Planned Project Facilities Table E.7.16 indicates recreation facilities proposed in the Susitna Hydroelectric Project Feasibility Report (Acres 1982d)• A single-status worker camp with a peak capacity of 3600 workers and a family-status village designed for a peak capacity of 350 families (1120 people)are planned.The v ill age is currently pl anned to be located about 1.5 mil es (2.5 km)north of the damsite,and the construction camp another 1.5 miles (2.5 km)northeast.An airfield will also be developed.After construction,the villages will be re- moved and relocated at Devil Canyon and a permanent townsite for 125 operators and thei r fami 1i es wi 11 be developed ad- joining the construction village.Current plans call for no preconstruction of the permanent town facil ities,necessi- tating a duplication of facilities in the temporary village and town site.The Dev il Canyon proj ect is pl anned to be constructed from a temporary single-status construction camp,and temporary family-status construction village located about 3 and 4 miles (5 and 7 km),respectively,from Devil Canyon.The camp is planned for a peak of 1780 workers and the village for 170 workers and their families, totaling 550 persons.No permanent residential facilities are planned for Devil Canyon. The temporary camps and villages are designed to be largely self-contained and in fenced areas,with highly regul ated environments.It is anticipated that hunting by project personnel will be prohibited and that fishing will be regu- lated.Recreation programs sponsored by the camp management will occur largely within these compounds. The Feasibil ity Report programs major recreation facil ities for each of the four temporary camps.Table E.7.15 shows the major facilities as anticipated in March 1982.Actual recreation facilities at the permanent town will be planned in detail during subsequent project design phases. (c)Recreation Programming for Workers and Residents Quality of life objectives are very difficult to achieve at construction camps.The type,number, and quality of E-7-97 5.4 -The Recreation plan recreation facilities and nonstructural opportunities available will be important factors in determining that qual ity of 1 ife t and could impact productivitYt turnover t and abil ity of the project to attract qual ity construction workers.It will also affect the nlmber of workers who choose to 1 ive and recreate out of the camp.Other things being equal t total environmental impacts can be reduced by concentrating the work force in camps rather than 1 iving el sewhere.Other important nonrecreation components which will affect quality of life are design considerations such as ability to achieve privacYt which experience has shown to be as important as recreational opportunities.Color and the use of interior pl antscapes are al so important.Other considerati.ons which are managerial in nature includes food qualitYt management styles t special event planning and holiday celebrations (see also Chapter 5 t Socioeconomic Impacts). Ancil1ary construction camp facilities are typically pro- grammed for less than peak work force because of the peak's relatively short duration.In terms of Susitna recreation t this concept is reinforced by the fact that annual peaks will occur in the summer months when outdoor nonstructural recreation will increase the range of recreational opportun- ities.While the peak work force at Watana will reach 3480 in June and July 1990 t the average annual work force will more closely approximate 1600 total workers.Only in the five years between 1987 and 1992 will the work force exceed this average t and then only during half of the year.Facil- ities will be completed by the 1990 peak;therefore t 1987- 1989 will incur the heaviest use.Devil Canyon construction activity will peak in 1998-2000 t and facilities will have maximum use in 1997.The permanent Watana townsite wll be planned for 125 famflies t or 400 total population. Assuming that the proportion of family and single-status workers remains constant t recreation in the Watana camps will be programmed as follows: - - - Single-Status Camp: Famil y Vill age: 1600 workers 160 workers (500 total popul ation) For Devil Canyon t comparable working forecasts are: Single-Status Camp: Family Village: 1100 wo rkers 110 workers (350 total population) E-7-98 - ""'"i 5.4 -The Recreation Plan Private recreational standards vary widely and are affected by location,climate,user profiles,and other factors. Representative standards intended,however,to be applied to larger,permanent communities are: ~I PopulationI Facil ity Standard ,~Softball 1 1000per Tennis 1 per 2000 Basketball 1 per 500 . Pool 1 per 20,000 Center 1 per 25,000 Gol f Course 1 per 25,000 Source:National Recreation &Park Open Space Standards (1971) - Other standards use 1 per 3000 popul ation for softball fields.Most planners would not use as high as 1 per 500 persons for basketball courts.Outdoor courts wi 11 be 1 imited by climate.Si mil arly,other standards use 1 per 50,000 persons for a golf course.Other standards determine athletic field needs in terms of acres per 1000 population, typ.ically 1.5 acres per 1000 for field sports (adults and older children)and 1.0 per 5000 population for tennis,out- door basketball and other sports (DeChiara &Koppelman 1978)• These types of standard planning criteria are not di rectly applicable to programming for these facilities.Some of the other factors which have influenced the recreation plan are the: /' Current construction plans call for five essentially sepa- rate cOlllTlunities which will require duplication of facili- ties and increase infrastructure and recreation costs.This recreation plan is designed to provide essentially equiva- lent facilities for single-and family-status workers.If -Extreme remoteness of the site; -Long duration of construction period; -Extreme harshness of climate from October through April; -Short daylight hours in wi nter months and long dayl i ght hours in summer months; -Long (10-hour)w~rk days; -Pattern of four weeks on,one week off; -Necessity to protect fish and wildlife from overuse;and -Homogenous user profile. ".. I E-7-99 5.4-The Recreation Plan family-status workers are not allowed,as is.more typical with civilian projects in Alaska,significant savings can be achieved.In addition,if permanent townsite facilities are pre-built for the Watana village,some duplication can be eliminated. (d)Proposed Recreation Plan for Workers and Residents The recreation plan as presented is designed for the peak year for Watana,1990-1991,and Devil Canyon,1998-2000,and w"ill be developed incrementally in the prior years,as needed.The plan is detailed in Table E.7.16. Recommended facil ities take into consideration those pre- sented in the March 1982 Feasibility Report,recent compar- able experience in construction camp programming,and refer- ence to recognized sources (DeChiara and Koppelman 1975 and 1978,DeChiara and Callender 1973,Mountain West Research Inc.1976,Myhra 1980). Many of these proposed recreation uses can be accommodated in multipurpose space.For instance,the gymnasium can be a multipurpose space suitable for jogging,basketball,volley- ball,tennis,badminton,etc.Such areas are not necessar- ily a separate building but are developed by clustering res- idential modules with flooring and roofing spanning the intervening space.The swimming pool can serve as the camp- fi re protecti on reservoi r and as an important image- generating and social gathering place.The "clubhouse"may be a separate structure or may be divided into smaller social groupings throughout the camp. Exterior uses likewise do not require separate space dedi- cated to a particular activity but can utilize single fields for multipurpose sports.Utilization of recreational directors is an important component both in maximizing the .multiuse potential of the facilities and in contributing to the quality of life for the residents. It is also recognized that some of the nonstructural activi- ties recommended in this plan carry liability risks for the Power Authority.Careful consideration will have to be given to the tradeoffs involved between quality of life and potential risks.Potential activities such as fishing will have to be carefully coordinated with the Alaska Department of Fi sh and Game to protect the resource.Other issues, such as storage of fi sh cal\ght by camp residents,have important Health Department implications.It is anticipated that no storage of fi sh will be permitted,nor will angl er fish be cooked in camp kitchens. E-7-100 -. - - 5.4 -The Recreation Plan Further recreation planning for the camps,villages,and townsite will be required as the Power Authority progresses with policy decisions regarding details of the construction program and as actual facility design is undertaken. 5.4.7 -Site-Specific Design The exceptionally large scale of the Susitna Recreation Area and regional approach to planning make detailed design of recrea- tional elements inappropri~te in Exhibit E. Site-specific designs will occur during Phase Two engineering designs at which time site-specific data and site locations will be accurately described and designed. These investigations of recreation sites will be closely coordi- nated with concurrent archeological site investigations..If potential conflicts are discovered between significant archeolog- ical sites and proposed recreational improvements,they will be resolved through careful siting and modifications as required. 5.4.8 -Design Standards The intent of this plan is to use the Alaska Division of Parks design standard,since this division will be the major managing agency for the proposed recreation sites.Because of the i n- tended primitive nature of most of the recreation sites,an onsite design construction process is most appropriate and is commonly used by the Parks Department.For example,the proposed trails will meet the Division of Parks "Priorities Trails"stan- dard which is an 18-inch to 24-inch (45-60 cm)tread surfaced in the parent material,with half logs in wetlands.They will be brushed out to 48 inches (1.2 meters)where necessary.They will be hand constructed and follow existing topography.Trails are intended to be as pr"imitive as possible to enhance the natural experience (see Appendix 7.C for typical or similar facility design standards for the Susitna project). 5.4.9 -Recreation Plan Mitigation Measures There were several considerations that were made during the rec- reation planning process to amel iorate the impacts of the pro- posed recreations sites.These concerns guided final selection of those sites. Avoidance of sensitive critical natural habitats and cultural or archeologic sites was a major consideration in the determination of the recreation plan.Each potential site was examined by an interdisciplinary group to define the suitability of potential E-7-101 5.5 -Alternative Recreation Plans recreation sites.Where critical habitats,environments,or cul- tural resources were in existence,those sites were el iminated or av oi ded. Some critical sites were impossible to ignore because of their inherent attractiveness and accessibil ity as a resul t of the project design.The approach in these cases was to direct rec- reation use to the most durable locations within the recreation zone being impacted.Critical fisheries or spawning grounds were not made accessible by the recreation plan.Critical minimal habitats (eagle nests,animal dens,etc.)were avoided,as well as all major,identified archeologic sites. Environmental situations including wetlands,steep slopes,and poor soils as observed in the field inventory,were also avqided. The intent of the recreation plan concept is to enhance and be an integral part of the existing landscaped character.Proposed recreational facilities will be primitive in their design char- acter and level of development in order to reflect this concern for fitness. Fi sh and game monitoring management will be necessary to ensure appropriate fishing and hunting use of these resources.These systems al ready exist within the study area and will have to be expanded. 5.5 -Alternative Recreation Plans In developing the Susitna Hydroelectric Project recreation Plan,a full range of alternatives was considered,including alternative levels of development,locations,and numbers of facilities.Also,the "no rec- reation facility"alternative was considered. Because recreational demand is low (Section 5),there is great fitness between the carrying capacity of the recreation sites and recreational demand.Therefore the "additional development"alternative was re- jected because of not satisfying project objectives of accommodating user demand,and appropriate levels of recreational development. 5.5.1 -Additional Facilities and Development In addition to the proposed recreation pl an,the alternative of additional recreational development was considered.This occurred in two ways:(1)additional new sites,and (2)more inten se development on the proposed sites. From the inventory,several sites were considered which had limited potential for recreation but were not chosen because of E-7-102 -. .... """I .j - , r- ! I r ,.... - 5.5 -Alternative Recreation Plans inherent 1 imiting factors.These factors included physical char- acteristics,accessibility,and recreation potential. Each proposed recreation site was evaluated for additional facil- ities.This was considered on an onsite basis for each site. 5.5.2 -No Recreation Facility Based on the physical character and operational characteristics of the project,it was determined that the reservoirs themselves do not constitute resources for recreation.The silty water, wide mudflats,slumping sidebanks,and potential choppiness are expected to discourage their use by the recreating public.Fur- thermore,potential safety hazards for small boaters suggest that publ ic pol icy not encourage use of proj ect waters for recrea- t ion.' However,if this "no development"alternative were chosen,pro- ject objectives of mitigating recreation losses would not be met, nor would induced recreational demand caused by improved access be accommodated.Not only will project roads increase access, but the reservoirs will become transportation routes for hunters. Thi s a lternat i ve was therefore rejected and'other recreati onal resources,not reservoir based,were considered for development of the plan. 5.5.3 -Other Access Route Alternative Many access route alternatives have been considered by project desi gners for access to the Watana and Devil Canyon dams ites. The proposed recreation plan and subsequent phasing have been determined considering accessibility as a major determinant.The difference between the proposed recreation plan and another access plan would be in the phasing order of the various recrea- tion sites for development and in the substation of some sites along that access for some of those along the current access. For instance,if the access to the Denali Highway were not built, the sites along it would not be recommended for development.If the north (east-west)access route were developed,sites along it (e.g.,Mermai d Lake)woul d be moved from Phase Four to Phase Two for fly-in or hike-in use.If the southern access route were chosen,all sites along or near the reservoirs would be developed only for fly-in or hike-in access until Phase Four,when the railroad would convert to recreational use. As part of the Phase Five monitoring,new sites might be located if demand warrants. E-7-103 5.5 -Alternative Recreation Plans 5.5.4 -Future Additions Because of uncertai nti es in both recreational demand and other factors such as u1timate land ownership,flexibility has been built into the recreation plan;this is more completely discussed in Section 6,Plan Implementation.Future additions may be sel- ected from the Phase Fi ve proj ects wh i ch were not selected for inclusion in the recreation plan but which may be considered in reserve for future additions,should demand be generated or should sites in Phases One through Four not be available due to land ownership or other reasons. E-7-104 -I I - """'I "'"".I - r- I -" r- I 6 -PLAN IMPLEMENTATION 6.1 -Phasing Phasing of the proposed recreation pl an is dependent upon a nlJ11ber of factors,including: -The schedul e on which Watana and Dev n Canyon projects are actually implemented,including dates on which reservoirs are filled and dates on which project access roads are opened to the public; -Agreement among the Power Authority and the various parties (Native corporations,BLM,state Division of Parks)on the schedule of pro- vision of those recreation areas which are not dependent on access roads utilized in project construction; -Agreement among the various parties on a recreation schedule.This schedul e is expected to meet and possi b ly exceed FERC requi rements for provision within three years,due to the extent of the project area,the extensive nature of recreational activity in Alaska,and the extremely long .and phased construction period; Sati sfactory and timely ag reement among the agenc i es and private landowners regarding possible recreational features on private 1 ands; -Demand for recreation,which is difficult to predict with confidence over the long project implementation period and in a state where pop- ulation growth,and hence the demand for recreation,is subject to major unpredictable variations in immigration rates.Availability of other regional recreational resources will affect demand in unpre- dictable ways as massive land status changes occur; -Schedul e of sel ection and tran sfer of 1 and titl e to the state'of Al aska and the Native corporations,which will determine actual own- ershi p at the time of impl ementati on of project recreation features, and whether a sufficient period (20 years)has passed to enable the Native corporations to sell the land;and -Potential information developed in the recreation-use monitoring pro- gram described in Section 6.2 below. Implementation of the Susitna Hydroelectric Project recreation plan is divided into five phases: 6.1.1 -Phase One:Watana Construction Phase This phase consists of recreational features intended to mitigate the impacts of recreational opportunities lost because of con- struction activities and associated land cldsures,to provide rec- reational opportunities for project construction workers;and to E-7-105 6.1 -Phasing provide the general publ ic with some early-on recreational bene-· fits derived from the public investment in Watana.Phase One projects are generally planned to be developed simultaneously with the start of project construction. 6.1.2 -Phase Two:Watana Implementation Phase , Phase Two consists of recreational features intend~~mitigate the impacts of recreation lost due to the operation of Watana,to provide for the recreational use potential of the project;to accommodate project-induced recreational demand;to allow public access to project lands and waters,and to protect the environ- mental val ues of the proj ect area.Phase Two projects ar~i n- tended to be developed within three years of the operational date of the Watana project 0 r when necessary agreements a re reached with private landowners for those projects on private land. 6.1.3 -Phase Three:Devil Canyon Construction Phase Phase Three consists of projects intended to mitigate the impacts of recreational opportunities lost due to Devil Canyon construc- tion activities and to provide recreational opportunities for con- struction workers.Phase Three projects are generally planned to be developed simultaneously with the start of access construction to Devil Canyon or when necessary agreements are reached with pri- vate landowners for those projects on private land.In addition, they will be designed to adjust to postproject recreational demand at Watana. 6.1.4 -Phase Four:Devil Canyon Implementation Phase Phase Four consists of recreational features intended to mitigate the impacts of recreation lost because of the operation of Devil Canyon;to provide for the recreational use potential of the proj- ect,to accommodate project-induced recreation demands;to allow public access to protect lands and waters,and to protect the en- vi ronmental val ues of the project area.Phase Four projects are intended to be developed within three years of the operational date of the Devil Canyon project or when necessary agreements are reached with private landowners for those projects on private 1and. 6.1.5 -Phase Five:Post-Construction Monitoring Phase Phase Five consists of monitoring recreational use.Monitoring wi 11 begin when the fi rst project recreati onal f acil iti es are available in order to determine actual recreational use of the project features and to trigger adjustments in the recreation plan as required.The triggering mechanicsm is designed to initiate E-7-106 ~I J- - 6.1 -Phasing any necessary adjustments in the Phase Two,Three,and Four plans and at 10-year interval s thereafter throughout the 1 He of the project license. 6.1.6 -Elements of the Recreation Plan According to Their Phases of Development (a)Phase One (Sites E,D,B,C,A,F) E Brushkana Camp 25 campsites west of existing camp water supply;and 3 vault toil ets. o Tyone River Confluence 1 shelter with Su sitna B Butte CreekjSusitna 1 boat launch at Susitna River Bridge.-C Watana Townsite'Temporary camp and town f ac i 1 iti es• 2 overnight shelters; 25 (41 km)miles primitive tra il ;and Tra il head and parking Middl e Fork Chul itna Ri ver Po rta1 signF A Explanatory entry sign;and 2-3 car pullout (b)Phase Two (Sites 0,U,H,I,L,J,K) r, r o Watana Damsite Vi sitor Center Parking,20 spaces;Visitor exhibit building;Food service;Souvenir shop; Museum;Restrooms;Powerhouse tour facil ity;Indi genous botanical trail;and Boat launch. -U Watana Towns ite (Phase Two) 2 miles (3 km)of primitive trail;to Tsusena Falls;and Trailhead an parking.

Therefore,Phase One of the recreation plan would be initiated at the time of starting construction.Phases Two,Three,and Four may be V modified based on Phase Five monitoring.In general,the Alaska Power Authority's commitment beyond Phase One is to acquire and develop the facilities listed in Phases Two,Three,and Four or their equivalent as agreed to by the relevant agencies and landowners as spelled out in the FERC 1 icense.Modifications to the plan may be according to the pro- visions of Phase Five -Postconstruction Monitoring Phase,as detailed be}ow.This proposed monitoring phase is written with the assumption that the Alaska Division of Parks will operate and maintain,witt,the financial support of the Alaska Power Authority,recreation elements located on state lands and,through cooperative agreement,on BLM lands.However,should the parties deem it desirable,separate agree- ments could be drafted with the BLM and IIBLM II be substituted for IIDivision ll accordingly.For project elements located on lands belong- ing to the Native corporations,a variety of ownership and management options may be available,and it is anticipated that similar agreements will be drafted.Construction of proposed facilities on these private lands is tied to acquisition·of necessary agreements with the Native corporations.If,after a reasonable amount of time,the Power Author- ity and the Native corporations are not able to reach agreement on a particular element of the recreation plan,the Power Authority,in cooperation with the Divison of Parks,will endeavor to find a site or sites suitable for the proposed recreation development on publ ic land· within the study area which are appropriate to the particular recrea- tionopportunitymatrix classification. E-7-109 6.2 -Monitoring and Future Additions 6.2.1 -Proposed Monitoring Phase The Division of Parks,with support of the Power Authority,will be responsible for maintaining facility use records and surveying use of Phase One recreation projects according to standards con- sistent with Division practice and sufficient to determine their level of use.At the time Watana reaches operation (or 10 years after the completion of ~onstruction of Phase 1 recreation facil- ities,whichever is earlier),the Division and the Power Author- ity will jointly meet to evaluate recreation use patterns and to plan schedules and levels of subsequent development,accordingly. The Phase Two (Watana Implementation)plan will be evaluated at this time and will be verified or modified as required consistent with the recreation opportunity preference as classification appropriate for each proposed element.Construction of the Phase Two recreation developments will be completed within three years of the joint determination of need by the parties.Need will be determined both by use levels of existing facilities and antici- pated demand generated by the completion of the Watana project. The Phase Three (Devil Canyon Construction)recreation plan will be similarly evaluated when construction of the Devil Canyon project begins.The elements recommended in this plan will then be veri fi ed or modi fi ed as requi red,based on experi ence at Watana and antici pated demand,consistent with the appropriate recreation opportunity preference classification of each project element.Phase Three will be constructed within three years of the joi nt determination of need by the parties. When Devil Canyon begins operation (or 10 years after the comple- tion of construction of Phase Three,whichever is earlier),the Division and the Power Authority will jointly meet to evaluate the Phase Four plan (Devil Canyon Operation),and similarly veri fy or modify it as requi red. At the 10-year anniversary of completion of construction of each phase throughout the license period of the project,the Division and the Power AuthorHy will jointly agree upon a plan for a major rehabilitation and/or construction relevant to the phase's initial projects.It is anticipated that the Division of Parks and the Power Authority will enter into an agreement whereby the Division agrees to perform the survey,evaluation,design,con- struction,operation,and maintenance of said recreation facil- ities on public lands with the costs to be borne by the Power Authority.It is also anticipated that agreements of similar intent will be entered into wi th the BLM and the Nat i ve corpora- tions as appropriate. It is intended that the Power Authority will commit to the costs of the facilities specified in this recreation plan.Should any E-7-110 ., I """,, - - - - ,.... I 6.2 -Monitoring and Future Additions phase be modified by joint agreement of the Power Authority and Division under the terms of this proposed monitoring plan,bud- geted monies may be transferred from proposed element to element and from phase to phase.This is done with the provision that total development costs in anyone phase do not increase over those in the original plan for that phase and that the total development cost for Phases One,Two,Three,and Four does not exceed the currently anticipated total cost,as measured in con- stant 1982 dollars. E-7-111 - - - '"'" 7 -COSTS FOR CONSTRUCTION AND OPERATION OF THE PROPOSED FACILITIES 7.1 -General The cost estimates associated with the proposed recreation facil ites and use are based upon 1982 prices for 1 abor and material s and the assumpti on that the Al aska Diy i son of Parks wi 11 admin i ster the con- struction,operations,and maintenance of the project areas.No land costs are included in this exhibit •.Additionally,all financial .responsibilities will be borne by the Alaska Power Authority.Costs of recreation facilities recommended for inclusion in the construction camps,construction villagE;!s,and permanent town are not included in this exhibit.No costs are included for Phase Five projects,as they will become a part of the recreation plan on y if monitoring determines that will be necessary. 7.2 -Construction A summary of estimated capital costs or each phase of the recreation plan is presented in Table E.7.17.'Breakdowns for these costs by project features are shown in Table E.7.18.The costs have been pre- pared based on State Division of Parks data and discussions with Alaska contractors. 7.3 -Operations and Maintenance It is intended that project recreation fac~lities will be operated and maintained by the State Division of Parks and/or the U.S.Bureau of Land Management,as appropriate.Table E.7.19 estimates additional equipment necessary to operate the proposed facil ities.Table E.7.20 summarizes estimated average annual costs for suppl ies,equipment,and personnel to operate the facilities.The State Division of Parks recommends that no user fees be assessed.

The ADNR expressed the desire to also provide recreational opportun- ities downstream from Devil Canyon.Sites in this downstream area will be assessed in the continuing project refinement studies. The USFWSand ADF&G have expressed concern with the increased access the Susitna Project will provide to important fish and wildlife re- sources.The development of the recreation pl an has,to the extent possible,taken this concern into consideration when siting the pro- posed recreational facilities.An effort has been made to avoid par- ticularly sensitive fish,wildlife habitat areas while maintaining maximum plan flexibil ity so that future recreational development can be directed away from these areas as they are identified through continued study.However,it should be noted that the resource management agen- cies will have an important role in reducing project impacts through regulation of hunting and fishing pressures placed on the resources. Responses to the speci fi c comments rai sed by these four agencies are contained in Chapter 11.

Appropriate access to the various settings is important in main- taining the setting preferences,e.g.,pristine activity prefer- ences need to be difficult to access.This relationship is deter- mined during the onsite field review. Attractiveness -is a measure of a landscape's unique or special set- tings and features.These can be both cultural and natural.The landscape was inventoried for features,their frequency and sig- nificance,which bear on the potential for recreation. Carrying Capacity -is the inherent capability of a landscape to sup- port recreation use.The primary purpose is to achieve fitness between the n unber of peopl e us i ng a site and the preferred rec- reation type (experience).The goal is not to reduce the experi- ential potential of site through over-use or participation. Encounter space -is that cover in acres within which an encounter with another individual can be anticipated.It not only includes physical contact (passing on a trail)but visual proximity as well)• Inherent Durability -is a general measure of the physical abil ity of a site to absorb the impact of recreation development.The evalu- ation is based upon known physical data and field observation of each recreation resource site. Natural Rarity -is a measure of the inventoried landscape features and settings based upon the frequency of occurrence and overall quality.Natural rarity also defines the physical characteris- tic's relationship to the regional and local scales. Recreatio",Opportunity Quality Factor -is based upon the natural rarity of a proposed recreation setting.It is used to determine the probability of capturing recreation users by simply saying the higher the rating for natural rarity the greater the potential for attracting recreation users. Recreation Preference Type - a pri ncipal objective ,of the recreation plan is to provide a variety of recreation activities within a spectrum of recreation ~preference types~.The preference types relate to the character and ~ual ity of the existing land base. The recreation activities also relate in terms of their appro- priateness to a p~rticl:ll ar setting.The four recreation prefer- ence'types are:pristine,primitive,semiprimitive,and deve 1o.ped. GLOSSARY (Cont'd) Rehabilitation Site -in addition to those recreation opportunities which are intrinsic to the natural environment,there are other areas under consideration such as borrow areas,construction and maintenance roads,~nd transmission corridors.These elements which are created to serve temporary purposes or as a by-product of construction commonly attract recreationists who find them con- venient for campsites;hiking trails,.offroad tracks,and other activities.AddHional recreation improvements and activities could be developed in such locations if unforeseen recreation demand occurs. Visitor Day Conversion Factor - a factor in determining the visita- tion capacity of a recreation setting which defines average use days by recreation preference type activities. Visitation Estimates -this method utilized two visitation estimates for each recreation site:(1)yearly visitation capacity;and (2). yearly visitation potential.Visitation capacity is an estimate of how many visitors can annually experience and use a particular recreation setting,based upon the designated recreation prefer- ence type. Visual Quality -is a measure of the scenic quality and importance of the site.The relative availability of significant landscape features and settings contained in each potential recreation site can be meas- ured by;rarity,levels of quality,manageability (reinforcing the Alaska landscapes image,and visual quality. -

The South-central Region is geographically bounded by the Alaska Range to the north and west,the Wrangell Mountai ns to the east, and the Chugach Mountains and Gulf of Alaska to the south.Char- acterized by rugged mountainous terrain,plateaus and broad river valleys.The regiOn is home to 55 percent of the state's popula- tion (Alaska Magazine,September 1981).Anchorage,with nearly half of Alaska's population and only 100 air miles (160 km)south of the project area,is located near the northeast end of Cook Inlet in the South-central Region. Mount McKinley,the state's single most significant geographical feature,is located on the region's northwest border.Spruce hem- lock and spruce-hardwood forests,wetlands,moist and wet tundra, as well as plateau uplands and a number of active glacier-bedded mountain valleys are other significant natural environments present here.This diversity of landscapes is al so complemented by a wide variety of wildlife and fisheries. The Interior Region is bordered by the Brooks Range to the north, the Bering Sea coast to the west,the Canadian border to the east, and the Alaska Range to the south.It is generally characterized as a broad open landscape of large braided and meandering rivers E-8-1 1.3 -Environmental Setting and streams.Ri ver vall eys are primari ly vegetated with spruce- hardwood forests giving way to treeless tundra and brush-covered highlands and large wetland areas.The Yukon River,which bisects the Interior Region,is its single most significant natural fea- ture.Again,as in the south-central region,the wildlife and fisheries are as diverse as the landscape environments (Alaska Geographic 1980). Fairbanks,100 air miles (160 km)north of the project area,is Alaska1s second largest urban center with approximately 30,000 residents.Due to a harsh winter climate and general inaccessi- bility other than by air,the Interior Region is still predomi- nately a wilderness area. 1.3.2 -Susitna River Basin The Middle Susitna River Basin,which surrounds the proposed hydroelectric site,is located entirely in the South-central Region.The 39,000 square mile (101,400 square km)area is bordered by the Al aska Range to the north,the Chul itna and Talkeetna Mountains to the west and south,and the northern Talkeetna plateau and Gulkana uplands to the east. Although the basin is not considered to be unusually scenic in comparison to other natural resources in Alaska,the aesthetic resources are valued because of the basin1s location between the two population centers of Anchorage and Fairbanks. The basin has distinct and diverse combinations of landforms, waterforms,vegetati on and wil dl ife speci es.The deep V-shaped canyon of the Susitna River and tributaries,the Talkeetna Moun- tains,and the upland plateau to the east are the dominant topo- graphic forms.Elevations in the basin range from approximately 700 feet to over 6000 feet (212 m to over 1820 m).Distinctive landforms include panoramic tundra highlands,active and post glacial valleys,and numerous lakes of both simple and complex forms.The most well known features in the basin are the verti- cal-walled Devil and Vee Canyons on the Susitna River.Devil Canyon contains some of North America's roughest whitewater. Seasonal changes in the basin,as throughout much of Alaska,are very dramatic.Lush green summers are replaced by the red,orange and golden colors of the tundra and hardwood species during a short autumn.Snow,ice and below-zero temperatures create a harsh,threatening but scenic winter landscape.Late April and May bri ng ice breakups on the ri vers and the once snow-and ;cecqvered ground beg;ns to come back to 1 He.The 1andscape turns green again as the cycle repeats. E-8-2 - '""'I ~, ~, - - - - - - .- -- 1.3 -Environmental Setting Other than the Susitna River itself,the silt-laden Maclaren and Oshetna rivers;the clear Tyone River;and Portage,Devil,Fog, Tsusena,Watana,Kosina,Jay,and Butte creeks are the major drainages in the Middle Susitna Basin.Scen"ic waterfalls occur on several of the creeks near their incised canyon confluences with the Susitna River,and the most notable falls occur on Devil Creek. Spruce and mi xed spruce-deci duous forests cover the bottom and slopes of river and tributary valleys below an elevation of 2500 feet (757 m)west of the Oshetna River/Susitna River confluence. Tundra and muskeg replace the mixed forests to the east and on the highlands.Mountai~slopes are bare or lightly covered with vege- tation. Wildlife species in the Middle Susitna Basin include Dall sheep, moose,caribou,and grizzly and black bears.Avian species include bald and golden eagles,trumpeter swans,and numerous mig- ratory waterfowl •Fisheries of the study area include all five Alaskan salmon species,grayling,burbot,rainbow,and lake trout. Because of the extremely turbulent waters of Devil Canyon,salmon are generally only found in the Susitna River below the canyon. Existing access into the middle basin area is generally limited to hiking,float planes,all-terrain vehicles (ATV),and watercraft. Denal i Highway passes through the northern portion of the basin linking the George Parks Highway to the west with the Richardson Highway to the east.Several short road/trails traverse the tun- dra to mining claims and fishing/hunting lodges.Primary human use of the basin includes recreational hunting and fishing. Several small mining operations are also found in the basin. 1.3.3 -Summary The Middle Susitna Basin is an essentially uninhabited and diverse environment which has regionally important aesthetic values.Any major development here has the potential to create significant aesthetic impacts within the basin as well as to both the South- central and Interior Regions.

E-8-10 ""'" - - """ 5 -EXISTING LANDSCAPE 5.1 -Landscape Character Types (Step 3) Landscape Character Types (LCT)are a description and classification of coherent units of the landscape which are used as a frame of reference to classify the physical features of an area.They are,for the most. part,based on physiographic units and represent land areas with common distinguishing visual characteristics such as landform,geologic forma- tion,waterforrn,and vegetation pattern.Using aerial photographs and USGS topographic quadrangles,the basic physiographic units were iden- tified and subsequently verified and inventoried in the field.The LCT for the basin are mapped in Figure E.8.5,and those for the transmis- sion are shown in Figures E.8.6 and E.8.7.The inventory includes four major landscape characteristics described as follows: -Landform: -Waterform: -Vegetation: -Views: which are physiographic units in terms of their degree of enclosure,geologic history and composi- tion,slope gradient and distinguishing landscape patterns,and exceptional natural features; which delineates the location of water bodies,lakes, ri vers,streams,and wetl ands,and the pattern and character of their occurrence.Rarity is also inven- -toried. whi ch is a descri pt i on of the vegetation patterns which exist within the basin.Special or unusual vegetation situations also are inventoried. which describe special visual characteristics within the landscape characater type and possible visitors or panoramic views to regional landscape settings. The fo 11 owi ng cha rts i dent ify and summari ze the 1andscape character types and the except i ona 1 natural features withi n the area.Numbered and asterisked items identify the outstanding natural features occur- ring in the landscape. These 1andscape character types can be eval uated for thei r aesthetic value (a relative measure of overall importance of the visual land- scape),including such components as distinctiveness,uniqueness,har- mony and balance (Step 5);and can also be evaluated for absorption capability (a measure of a landscape1s natural sensitivity of a land- scape to a lterat ion).Factors such as the potential for human experi- ence,compatible site relationships,and aesthetic values are con- sidered (Step 6). E-8-11 ST \-3 LANDSCAPE CHARACTER TYPE MID SUSITNA RIVER VALLEY PHOTO LB.l LANDFORMS Valley is 2 to 6 miles (3 to 10 km)wide with steep slopes.

E-8-31 - .- - - - ..- 6 -VIEWS (STEP 4) Evaluation of existing landscape character types and their inherent aesthetic quality is independent of the issue of visibility.Quality does not depend on vi si bi 1 ity.However,the eval uat i on of aesthetic impacts is directly related to the potential for viewing any particular site. Vi ews are descri bed as di stant or panorami c,and near or foreground views.Panoramic views or vistas are irnportant for perceiving and experiencing the overall landscape context.Explanatory vistas are those where the observer has the opportunity to view large scale land- mark or landscape settings symbolic of Alaskan environments.An example would be the opportunity to view the Alaska range.Foreground views are those within the immediate vicinity of the observer. The level of impacts is determined by analyzing the relationship between a proposed facil ity and the existing landscape.The two impor- tant aspects of this evaluation are the observer position and the dura- tion of the view. Observer position is the location of specific places or settings where an individual can "view"the landscape.Within the study area,this opportunity occurs principally along the access roads;however,other observer postions are included,based upon the proposed development including recreation sites,known existing use areas (e.g.High Lake Lodge),and the damsites themselves. These observer positions were evaluated on an on-site basis regarding the relative existence of specific landscape character types,opportun- ities for extended views or vistas into the surrounding environments (e.g.,the Alaska Range),and major views of project facilities.These are mapped in Figure E.8.8. Within the study area,potential observer positions include aerial views from small plane traffic and ground views from vehicular traffic on project roads,random foot traffic throughout the area,boat traffic on the Susitna River,and users of the various recreation and hydro- electric facilities. The duration of views is also an important consideration.This is a measure of the extent of time one has to vi ew a part icul ar 1andscape setting.ThB longer the time frame for viewing,the more significant the measurement of the observer position becomes. These elements were considered during the evaluation of aesthetic impacts and are reflected in the charts of Appendix 8.F • E-8-33 ..... - ,..... 7 -AESTHETIC VALUE RATING AND ABSORPTION CAPABILITY RATING 7.1 -Aesthetic Value Rating (Step 5) Each landscape character type (Step 3)was evaluated for its relative aesthetic value on a high,medium and low basis.Aesthetic value is defined as a relative measure of the visual landscape based upon the following characteristics. 7.1.1 -Distinctiveness A measure of the visual impression of an area;i.e.,a landscape where 1and forms ,waterforms,rocks,vegetative or soi 1 patterns are of outstanding and memorable aesthetic quality. 7.1.2 -Uniqueness A measure of the relative scarcity or commonality of the land- scape.Due to AlaskaJs vast and numerous high-quality landscapes, uniqueness will have two levels of meaning for the purpose of this report: -Landscapes and natural features mayor may not be rare on a statewide scale;and -Landscapes and natural features mayor may not be rare on pro- ject area scale. 7.1.3 -Harmony and Balance A measure of the degree to which all elements of the landscape form a unified composition.This includes the integration level of man-made elements in a natural setting. These characteristics were evaluated by on-site examination of each 1andscape character type.This on-s ite approach al so con- sidered the visibility and potential for views (Step 4)in genera- ting aesthetic value ratings. 7.2 -Absorption Capability (Step 6) Each landscape character type was evaluated for its absorption capabil- ity,which is the relative ability of a landscape to absorb physical change.Each character type was rated on a high,medium and low basis based upon the following characteristics:aesthetic value (step 5), topographic enclosure,vegetation cover,ground plane color and visi- bility.Each landscape character type was evaluated with an on-site examination of the aforementioned characteristics as related to poten- tial project facilities.The following chart presents the ratings for the aesthetic value rating (Step 5),and the absorption capability (Step 6).

Design Criteri a New elements may add to the aesthetic quality beyond existing conditions by introducing , visual interest and/ or complementing the landscape. This chart summarizes the inherent quality of the landscape for aesthe- tic impact analysis (Step 8)and mitigation measures to reduce adverse aesthetic impacts (Step 9). E-8-42 ,~ ..... - 8 -AESTHETIC IMPACT RATING (STEP 8) Aesthetic impacts are a result of introducing various project struc- tures or manmade landscape el ements such as transmission right-of-way paths into an existing .environment which is subsequently seen by people.Aesthetic impacts also result from the loss or inundation of existing landscapes and their "replacement"with altered or new land- scapes which have different aesthetic qualities. Aesthetic impact ratings describe the relationship of the proposed facilities and the inherent qualities of the landscape character types. Aesthetic impacts are determined by comparison of the project features to the aesthetic impact ratings (composite ratings,Step 7)for each landscape character type.There are two categories of potential visual impact when project facilities are developed,(1)compatible aesthetic impacts are those that are in harmony with the existing landscape char- acter,and (2)incompatible aesthetic impacts which are obtrusive in the existing landscape character • Compatible aesthetic impact ratings are evaluated on the basis of two criteria,(1)the facility is subordinant to the landscape character type and compatible in the character of the facilities design solu- tions,and (2)the tyoposed facility design solution is high in aesthe- tic val ue on its own merits,and compatible with the existing landscape character type. Incompatible aesthetic impact ratings are evaluated on the basis of negative contrast or visual discord between the proposed facil ity and the existing landscape character.Aesthetic impact ratings are des- cribed for each 1Y0ject feature in Appendix 8.F. 8.1 -Mitigation Planning of Incompatible Aesthetic Impacts Except for a few project features,it is possible to reduce the aesthe- tic impact of features by employing appropriate mitigation planning. Each proposed feature was initially rated as currently sited and designed.If the aesthetic rating was compatible,no mitigation is necessary.If the aesthetic impact rating is incompatible and mitiga- tion is possible,the project feature1s adjusted rating is shown taking into consideration the mitigation measure applied which may change the aesthetic impact rating to compatible in some cases.In other cases, aesthetic impacts may continue to be incompatible but lessen the sever- i ty of the impact. If mitigation can be accomplished through redesign,the feature is assigned a new rating in the last column of the chart in Appendix 8.F. E-8-43 8.1 -Mitigation Planning of Incompatible Aesthetic Impacts The type of mitigation suggested is indicated on the charts with letters;for example,a Ca rating would indicate that a project featlJre could be made compatible with proper employment of type (a)mitiga- t ion. One or more of the following four generic types of mitigation can be employed to achieve the proposed level of mitigation: -Additional study required to consider alternative solutions,sites or corridor alignments with less impact on scenic quality; -The use of best development practices to minimize construction- related effects on the landscape and to guide post-construction cleanup and rehabilitation of disturbed areas; The use of creative engineering design to assure that project fea- tures are well designed and are in themselves positive visual fea- t ures;and -The use of form,line,color or textures appropriate to the landscape character type. The following example chart illustrates this process: E-8-44 PROJECT FEATURES PROJECT FEATURE WATANA PROJECT AREA 1 - 9 .-1 WATANA DAM FEATURE DESCRIPTION- IMPACTS STEPS 7.8 ..... Earth-fill dam.

E-8-45 I"'" I I .... 9 -MITIGATION (STEP 9) Mitigation measures have been designed to protect the quality of the existing landscape by prevention or repair of negative impacts caused by human activity an~development. The measures are also intended to enhance the existing environment in the following ways: -Improve opportunities to appreciate the areas of high aesthetic qual ity; -Improve the aesthetic quality of proposed facilities;and -Maximize the positive relationships of the proposed facilities to the existing landscape. 9.1 -Mitigation Measures The four major categories of mitigation identified in Section 7.1, Mitigation Planning,include: -Additional studies; -Best development practices; -Creative engineering design;and -Use of form,line,color and texture. The fo 11 owi ng techn i ques desc ri bed in these categori es respond to general conditions which may occur throughout the development.Speci- fic impacts of individual project facilities are identified in the mit- igation measure charts located at the end of this section. A summary of impacts for the Watana site,Devil Canyon site,access roads and transmission lines also follows. 9.1.1 -Additional Study During the Phase II detailed design process,an interdisciplinary des i gn .team wi 11 be assembl ed to resol ve the aesthetic'impacts identified in Exhibit E.These aesthetic impacts will be further ameliorated through site specific design analysis and development. Aesthetic impacts to the design solutions include: (a)Siting Studies Siting of facilities can be used to reduce visual intrusion into the exi sti ng 1 andscape and mi nimi ze requi rements for grading and other disruptions.By utilizing local conditions such as topographic changes and vegetation,the inherent absorption capabilities of landscapes can be maximized • E-8-47 9.1 -Mitigation Measures The need for mitigation measures"in the facility designs also will be reduced by avoiding particularly sensitive locations such as wetlands,discontinuous permafrost zones and other areas which would require extensive modification. Siting can be used to maximize the potential for enhancing the aesthetic experience.Examples of this include:facility locations to take advantage of spectacular view opportunities and siting facil ities such that they enhance or compl iment their setting. Other specific examples of mitigation through siting include: Facility siting can be used to mlnlmlZe requirements for clearing or removal of vegetation.Structures should be consolidated as much as possible to disturb the minimum necessary area of ground surface; -Facility will be sited to avoid thaw-susceptible areas (discontinuous permafrost zones)capable of slumping or thermal erosion; -Solid waste disposal sites will be located in stable,well- drained locations.Siting will utilize existing excava- t ions such as depl eted upl and borrow pits.Intermittent drainages,ice-rich sons,or other erosion-susceptible features will be avoided; Transmission line additions should be located adjacent to established transmission corridors.Where transmission lines have a common destination,they should follow a common route;and -Transmission corridors should follow the forest edge as much as possible (i.e.,the transition zone between forest and shrub or forest and tundra)versus cutting through dense woodlands.Lines should avoid crossing wetlands. (b)Alternative Solutions In some instances the facility chosen to serve a spec ifi c project function may not be the design solution which least impacts the aesthetic resources.This will be considered only in cases where present solutions would be difficult to mitigate even with modifications. E-8-48 9.1 -Mitigation Measures 9.1.2 -Best Development Practices Construction and rehabilitation,as well as operation policies, are often as important in mitigating facil ity impacts as is the facilities actual design.Throughout the Susitna project,general development policies which mitigate or prevent impacts will include: (a)Construction Techniques Construction equipment and vehicles will be confined to gravel roads and pads or designated construction zones. All off-road or all-terrain vehicles use will be prohibited on the site by individuals. Temporary facil ities such as roads,construction zones and storage yards will be located to minimize the impacts and therefore the rehabilitation needed. Borrow sites will be excavated according to a site priority program developed by the desi gn phase contractor.Those sites which will cause least impacts will be exploited first with the identified sensitive areas utilized last and only if all other sources are exhausted.Material sites will be planned and mi ned in such a way as to fac i1itate restora- t ion. Abandoned access roads,camp pads,and airstrips will be used wherever feasible as material sources for operations,in lieu of expanding existng sites or initiating new ones. Where riprap is required,material produced during excavation of the powerhouse,galleries,and tunnels will be used if feasible. Where they are not adjacent to an existing road,transmission corridors should be constructed to avoid unnecessary clearing of vegetation.In tundra location where clearing is not required for access,minimum ground disturbance vehicles such as Roligon or flat-tread Nodwell-typevehicles should be used.Transmission corridor development should avoid creat- i ng an alternati ve access route for all-terrai n vehi cl es. All debris generated by construction activities will be removed after completion. Excavation spoil will be disposed of in the future impound- ment area of the dam under construction.Where haul dis- tances prohibit this,spoil disposal sites will be placed in stable,well-drained upland locations. E-8-49 9.1 -Mitigation Measures Limits of construction activity and storage will be defined during the design phase so that vegetation clearing and soil disruption can be minimized.Where removal of vegetation is required,organic overburden should be segregated and stock- piled for use in subsequent rehabilitation. (b)Rehabilitation Techniques Di sturbed rock cuts wi 11 be roughly bl asted to forms simil ar to existing natural conditions.Construction areas not required for project operation will be "pu t to bed II as soon as they are no longer requi red (duri ng the same season,if possible).Restoration should include scarification and fer- tilization.Non-operational roads will be structurally altered to restore normal drainage patterns. Organic overburden,slash,and debris stockpiled during clearing will be distributed over the excavated areas prior to fertilization.This includes borrow sites which haNe ponded.Once operational material sites are depleted or no longer requi red,they shoul d be rehabi 1 itated by the end of the next growing season following last use. Equipment,structures,and materials should be removed from a site prior to rehabilitation.The site should be graded to contours which are consistent with surrounding terrain and allow complete drainage with minimal erosion potential. Where it can be demonstrated that erosion is not likely to be a problem,restoration should emphasize fertilization and scarification,and minimize seeding,to encourage the inva- sion of native plants from the surrounding parent population. Where seeding is employed.native grasses appropriate to the climate and geography of the project area should be used. (c)Operation Policies On project lands,off-road and all-terrain vehicles will be restricted to designated maintenance trails. Concurrent with other educational programs for Susitna workers and resident,s,an organi zed effort will be made to increase the awareness to the aestheti c envi ronment,i.e., refuse disposal,vandalism and indiscriminate use of fragile environments. 9.1.3 -Creative Engineering Design Many of the project facilities are not inherently incompatible with the 1 andscape character type in which they have been sited £-8-50 .... -I 9.1 -Mitigation Measures a nd represent an opportunity to enhance the exist i ng 1 andscape character.In the cases where this opportunity is identified, careful design study during the design phase will maximize the aesthetic value potential.The Devil Canyon dam is an excellent example of creative engineering solution resulting in a positive impact.Other design related mitigations include the following: -Road profile elevations will be minimized and side slopes made sufficiently gentle to blend into existing contours;and -To minimize excavation disruption,facility design will minimize gravel requi rements by avoidance of wet areas or permafrost zones,structure consolidation,and balanced cut and fill. 9.1.4 -Use of Form,line,Color,or Textures Some aesthetic impacts caused by project facilities can be greatly reduced by modifying its appearance to blend into the surrounding landscape.This can be accomplished by repeating predominant existing conditions such as: -The colors of soil vegetation or sky; -Forms of topography such as massi ve low hi 11 s or angul ar rock cliffs; -Line:This includes elements such as the vertical orientation of spruce forests or the horizontal character of a lake;and -Texture:Exi sti ng rough and dull surfaces shoul d be approxi- mated and shiny materials prone to glare avoided. 9.1.5 -Mitigation Costs The aesthetic mitigation plan is designed to reduce or eliminate adverse impacts due to development.The emphasis of the mitiga- tion measures is to:(1)avoid critical environments including on- going site refinements throughout the design phase:(2)use best development practices and site sensitive engineering;and (3) rehabil itation. Avoidance of difficult or impossible site conditions will generate considerable cost savings in both site construction and opera- tions.Many situations of this kind have been addressed in Exhibit E throughout the evolution of the various project plans. As part of ongoing supplemental and future planning throughout the design engineering phase,additional study for aesthetic mitiga- tion will include siting studies,avoidance of difficult site specific physical conditions and visual compatibility with the existing landscape setting. E-8-51 9.1 -Mitigation Measures No additional project costs are identified on the basis of avoid- ance of difficult site conditions as part of the ongoing engineer- ing planning and design work. Future cost savings for aesthetic mitigation measures include best development practices for site design engineering and construc- tion.Creative engineering design,progressive construction tech- niques,and future operation policies are prescribed as aesthetic mitigation measures.These measures will not add to the cost of engineering or construction practices and have the potential to reduce the actual cost of construction and development. Rehabilitation techniques are an integral part of the construction process and are essential to the visual and aesthetic qual ity of the project.The proposed mitigation measures for rehabil itation are a normal part of good engineering practice and should not cause additional project cost.For pertinent related mitigation measures,refer to Chapter 3 of Exhibit E. These mitigation measures will also have a positive aesthetic resul t. E-8-52 ~l AESTHETIC RESOURCES PROPOSED MITIGATION MEASURES STEP 9 ....

Although the proposed route was selected for its high ability to cause minimal adverse aesthetic and enVlronmental impacts,the large scale of the feature in relation with the highly aesthetic landscapes through which it passes results primarily in an lncompatible situa- tion.Mitigation measures are possible in many conditions to assure minimal aesthetic impacts,and in some cases make compatlble relationships. •The selection of CO~TEN-surfaced towers will reduce their visibility in the landscape. •Right-of-ways through forested areas should be feathered to reduce tunneled or channeled visual effect. •Complete clearing of vegetation in right-of-way is unnecessary.Trees should be topped to a 30-ft (9-m)radius of the conductors and maximum line sag. •Where possible,alignments should follow the edge of major forest/open boundaries to minimize clearing and maximize screening potential. •Ridge tops and other high points are to be avoided because of their high visibility. •Alignment through valley centers should be avoided as these areas would become major focal points as would ridge tops. •utilizing helicopter construction methods in inaccessible and environ- mentally sensitive areas will help reduce adverse aesthetic impacts. •Winter construction using rolligon vehicles in open tundra areas will eliminate the potential visual impacts caused by the construction of access roads/trails during other seasons. •Use of existing roads near alignment sections will eliminate the need for new construction area access.Short roads/trails to tower construction areas should be aligned and designed to cause minimal damage to the landscape. •The crossing of Devil Canyon area with transmission lines is viewed as incompatible with no mitigation measures to make it compatible. However,creative engineering design and proper siting of towers will lessen adverse impacts.The maXlmum allowable span across the river, with towers at the top of the canyon,should be used to keep the lines high above the river and eliminate clearing of canyon wall vegetation. •Educate project workers and especially equipment operators in construction methods whlCh result in minimal environmental impacts which directly relate to aesthetic impacts.Identify environmentally sensitive areas.Use visual alds to stimulate interest. •River,stream,canyon and road .crossings should be made at 90-degree angles.

Since this new facility will carry power generated by the Susitna Pro- j ect over a system expanded to serve the proj ect as shown in Fi gure E.8.4,it is briefly discussed herein. 10.2 -Project Description The Intertie will extend from Willow and Healy,where it will ulti- mately connect with Susitna Hydroelectric Project features referred to as "Stubs".Figure E.8.4 illustrates the Intertie as it is planned to be constructed in 1983;along with subsequent additions for the Susitna Project,including the stubs and dam interconnections.The Intertie· will be a 170-mile (280-km)long facility constructed basically of guyed steel "X"poles •.Angle structures will be three separate verti- cal pole structures with single-pole hillside structures.All towers will be made of self-rusting (Corten type)steel and conductors will be nonspecular.All facilities and structures will be identical to those described in the visual analysis of the Susitna Hydroelectric Project transmission lines in previous sections of this report.At initial construction,the intertie line will be energized at 138 kV. When the Watana Project comes on line in 1993,a second parallel line will be added to the Intertie,the "stubs"will be constructed,the lines will be energized to 345 kV,and a switchyard built near Gold Creek to connect with Watana power.In 2002,when Devil Canyon comes on line,a third parallel line will be built on the Gold Creek to Willow portion of the line,and the Willow to Anchorage stub will also have a third line. This discussion will briefly cover the Willow-to-Healy route as analyzed by Commonwealth for 1983 construction,and will comment on the 1993 and 2002 additions to the Willow-to-Healy route. 10.3 -Landscape Character Types Commonwea lth i dent ifi ed six 1 andscape cha racter types based on the Alaska Department of Natural'Resources 1981 study,Scenic Resources Along the Parks Highway.They are: -Su sitna Ri ver Lowl ands: Denali State Park; Cook Inlet to the southern entrance of -Curry Ridge:Denali State Park to Curry Ridge; E-8-61 10.3 -Landscape Character Types -Chulitna River:Curry Ridge to East Chulitna River; -Broad Pass:East Chulitna River to Denali Highway; Alaska Range:Denali Highway to first Nenana River crossing of Parks Highway at southern boundary of Denali National Park;and -Nenana Gorge:Nenana River crossing to Healy. However,for the purpose of this analysis the following types have been delineated: -Susitna River Lowlands; -Talkeetna Mountains; Chul itna Ri ver; -Broad Pass; -Al aska Range; -Yanert River Valley;and -Nenana Uplands. Therefore,these were the units analyzed for the purposes of this report. These 1andscape unit types and the approximate poi nt of i ncl i nat ion (PI)of the transmission line are as follows. 10.3.1 -Susitna River Lowlands (Willow Substation to PI 14 at the crossing of the Talkeetna River.) Extendi ng south from near the town of Ta 1keetna to its mouth on Cook Inlet,the broad and heavily braided Susitna River flows through a topographically flat,sometimes rolling landscape. Muskeg bogs and hundreds of relatively small lakes and ponds are scattered over the land. Sparse bl ack spruce bogs are found on the poorly drai ned areas while moderate to dense spruce-deciduous forests exist in areas with higher relief. Paralleling the Susitna from near the towns of Willow and north to Ta 1keetna,the Parks Hi ghway is the shortest and most frequently used access route between Anchorage and Fa i rbanks.A number of small communities and recreation sites occur along or near the road.In addition,the Alaska Railroad also parallels the Susitna River and Parks Highway here. E-8-62 .... .... 10.3 -Landscape Character Types Many of the larger and more scenic lake areas are popular summer and permanent home sites for hundreds of south-central Al askans. Some are accessed-by road whil e others are only reached by float- plane. Spacially open areas offer views to the Tal keetna and Chuga~h Mountai ns,and the Alaska Range.Mount McKinley is to the north and the flat topped Mount Susitna is nearby to the southwest. 10.3.2 -Talkeetna Mountains (PI 14 to PI 41 above the crossing of the Susitna River.) Whil e the Department of Natural Resources study cl assifi es thi s area as the Talkeetna Mountains,for the purposes of this trans- mission line study that designation has been subdivided into three subtypes: -Talkeetna Mountains to the south and west of the transmission corridor; -Talkeetna Lowlands;and -Talkeetna Uplands. The proposed alignment passes through these latter two character types which are described below. 10.3.3 -Lowlands Portion After steeply rising several thousand feet from the Susitna River valley,the landscape in the lower Talkeetnas becomes a rolling terraced plateau.The average elevation is around 3000 feet (900 meters)with a few knobs rising above 4000 feet (1200 meters). The domi nant tundra envi ronment here is very wet and contai ns hundreds of small lakes and muskeg bogs.Spruce trees are scat- teredthroughout the area,but usually are found at lower eleva- tions within the drainages.Gold,Cheechako,Chulitna and Disap- pointment Creeks are among the more scenic drainages. The flat and rolling character of these uplands affords panoramic views to the Alaska Range,Chulitna and Talkeetna Mountains. Views of the surrounding river valleys from high points and ter- race edges are also very good • Access into the area is predominantly by floatplane,snowmobile, and use of a few existing mining and/or settlement trails • E-8-63 10.3 -Landscape Character Types 10.3.4 -Uplands Portion Approaching its confluence with the Susitna River,the braided Talkeetna River and western tributaries pass through a terraced and hilly landscape.This area is mostly covered with a dense spruce-deciduous forest.Muskeg bogs are common but not as expan- sive as in the Susitna Lowlands. There are a number of 1akes in the area used both for recreat i on and home or cabin sites.Approximately 4 miles (7 km)long,the narrow Larson Lake is the largest of these. The dense forest cover restricts vision,but scenic views of the Alaska Range,the Talkeetna and Susitna Rivers,and the immediate Talkeetna Mountains proper,are possible from occasional elevated spots and widened river channels.. Access into the area is primarily by foot,floatplane,boat and a limited number of jeep,all-terrain vehicle,or horse trails. 10.3.5 -Chulitna River (PI 41 to PI 48 on the Chulitna River.) Dividing the Alaska Range and Chul itna Mountains,this flat-to- rolling river valley is predominantly an open tundra-covered land- scape.Sparse-to-moderately-dense spruce-deciduous forested areas occur along the meandering Chulitna River and its tributaries. The dominant Alaska Range rises gently from the valley in compari- son to the steep rise of the Chulitna Mountains.Hurricane Creek and Gulch form a dramatic descent from the Chulitnas.Spectacular mountain,glacier and valley views are offered in open areas and vantage points. The Al aska Ra il road and George Parks Hi ghway parall el the ri ver along the upper slopes and terraces on the Chulitna Mountain side. Several small road-and railroad-related communities and a few designated recreational sites occur here "in the vall ey.Portions of the Parks Highway between Chul itna Pass and Broad Pass have been recommended for scenic highway designation by the Alaska Department of Natural Resources. 10.3.6 -Broad Pass (PI 48 to PI 65 north of the Nenana River.) Over 10 miles (16 km)wide near the town of Broad Pass and narrow- ing to 4 miles (7 km)wide near Cantwell,this area known as Broad E-8-64 - r"'*. 10.3 -Landscape Character Types Pass separates the Al aska Range and the northwest Chul itna Moun- tains.This open,flat-to-rolling landscape is very scenic with its long and linear lakes,variety of tundra and spruce cover patterns,and mountain views. The Parks Highway goes through the northern side of the pass near the Denali Natural Monument boundary.The Alaska Department of Natural Resources recommended in their 1981 Scenic Resources along the Parks Highway report that the road between Broad Pass (town) and Windy be considered for scenic designation.The Alaska Rail- road passes through the Summit Lake area and parallels the highway. Cantwell is the west junction of the Denali Highway with the Parks Highway. 10.3.7 -Alaska Range (PI 65 to midway between PI 70 and PI 71 on the southern edge of the Yanert Ri ver Vall ey,and PI 74 to PI 83 near Moody Creek southeast of Healy.) Featuri ng North Ameri ca I s hi ghest mountai n,the U-shaped Al aska Range extends nearly 600 miles (1000 km)from an area west of the Cook Inl et to the Al aska-Canada border.Thi swell-known mountai n range with its hundreds of glaciers is the dividing feature of the interior and south-central region of Alaska.Elevations range from approximately 2000 feet (600 meters)in adjacent valley to over 20,000 feet (6000 meters)at Mount McKinley. 10.3.8 -Nenana Uplands (PI 83 to PI 85 Healy Substation Site.) Extending north from the Nenana River Gorge to the flat Nenana Low- lands,the river becomes progressively more braided as it flows through a roll ing and terraced valley.Sparse spruce-deciduous stands are found near the river bottom while moderately dense forests cover much of the upper terraces.Rock outcrops are common along the edges of the rising terraces. Vi ews are di rected to the east where the terraces ri se up to the higher-relief Alaska Range foothills.While the Parks Highway and Alaska Railroad do not significantly degrade the visual quality of the landscape,existing transmission lines do present a negative aesthetic impact. 10.3.9 -Yanert River Valley (PI 71 to PI 74.) E-8-65 10.6 -Impacts A 35-mil e swath through the Al aska Range east from the Nenana River,the Yanert River Valley ranges from 2 miles (3 km)in width at the Yanert Glacier to over 5 miles (8 km)at the confluence with the Nenana.The Yanert River is heavily braided for most of its length before turning into a broad fixed channel river for the last 5 miles (8 km).The valley is tundra dominated with scattered stands of spruce adjacent to the ri ver bottom.The Al aska Range rises steeply from the valley near the glacier.Gently sloping terraces up to the mountains become progressively longer as the valley opens into the adjoining Nenana River Valley. 10.4 -Description of the Preferred Route The preferred transmission line route extends 170.1 miles (280 km)from the proposed Willow substation site to the proposed Healy substation and can be generally described as follows. Willow Substation is proposed to be located near Willow Creek about 1.5 miles (2.5 km)east of the Parks Highway.Then the alignment follows the Matanuska Electric Association right-of-way approximately 19 miles (32 km)north.It continues in the Susitna Lowlands until Chuni 1 na Creek,northeast of Talkeetna,where it proceeds east and up into the Talkeetna Mountains before dropping back to the Susitna River near Gold Creek.The alignment then proceeds due northeast of Chulitna Butte and joins the Chulitna River Valley.It generally parallels the river valley,Parks Highway,Alaska Railroad corridor,through Broad Pass,and north up the Nenana River Valley to the Yanert Fork.The line then jogs east of Sugar Loaf Mountain,northwest down Moody Creek,and continues ina northwesterly direction into Healy. 10.5 -Alternatives Many minor route a~justments and subalternatives were considered by Commonwealth.Three major alternatives were considered: An alignment paralleling the Parks Highway from south of Sunshine to Chul itna Pass; -An alignment west of the highway from Broad Pass to the first Nenana River crossing of the highway;and -An al ignment along the Nenana Gorge rather than east of Sugar Loaf Mountain. In addition,alternative pole configurations were considered and rej ected. E-8-66 r~, - - - 10.6 -Impacts 10.6 -Impacts A cursory examination of visual impacts based on aerial and limited ground inspection of the preferred and alternative alignments,stuay of USGS topographi c maps,and ana lysi s of the 'Commonwealth report, follows. 10.6.1 -Susitna River Lowlands The line will generally be distant enough from the Parks Highway and screened by vegetation in this low landscape unit type that it will be largely unseen by most viewers on the ground. 10.6.2 -Talkeetna Mountains The line will be highly visible as it crosses the Talkeetna River, an important recreational resource.Parti cul arly when the Inter- tie is expanded to two and then three lines,visual impacts will be significant at this point.The route over the mountains north of the river will not be'generally visible until it again nears the Susitna Ri ver,when it wi 11 be in full vi ew from Curry Ri dge in Denali State Park. 10.6.3 -Alaska Range The line(s)will be highly visible along the Indian River,at two crossings of the Alaska Railroad,and from portions of the planned remote parcel land disposal areas between Gold Creek and Hurri- cane.Further north,between Cantwell and the Yanert Fork,the lines will pass close to the Parks Highway in areas rated by Department of Natural Resources (DNR)as havi ng low-to-moderate absorption capability. North of the Yanert Fork,the route east of Sugar Loaf Mountain was selected to eliminate visual impacts in the highly scenic Nenana Gorge area. 10.6.4 -Chulitna River From about Honol ul u Creek to the east fork of the Chul itna,The Department of I~atural Resources has rated this portion of the Parks Highway one of moderately high scenic resources and moderate-to-low absorption capabi 1 ity.Whil e predomi nant vi ews are to the west,the transmission line will be visible to the east. 10.6.5 -Broad Pass DNR recommends that this area be officially designated a scenic highway.Because of the landscape's low-to-moderate absorption E-8-67 10.6 -Impacts capability,they recommend no development within 1 mile (1.6 km) of the Parks Highway.The al ignment ranges from a few hundred feet (approximately 80 meters)to approximately 2 miles (3 km) from the highway as it passes through this unit.Visual impacts will be high.The crossing of the Denali Highway,currently under study by the Bureau of Land Management for scenic highway designa- tion,will also be in full view. 10.6.6 -Yanert River Valley Crossing this valley,the alignment is approximately 2 miles (3 km)east of the highway and will not have major impacts. 10.6.7 -Nenana Uplands The location of the Healy substation near the Alaska Railroad and Nenana Railroad will be highly visible and have negative visual impacts.

The concerns raised by these two agencies include: -Incorporation of mitigation measures in project design; -Use of avoidance as a mitigation measure;and -Access road location and design criteria. In response to these concerns,the mitigation section has been expanded and strengthened to include additional mitigation measures in the pro- ject design during the detailed design phase.In addition,the Alaska Power Authority through an interdisciplinary task force will be reass- essing the transmission and access road al ignments before final design of these two features is undertaken. Responses to the specific comments raised by these two agencies are included in Chapter 11. E-8-70 ..... REFERENCES Acres American Incorporated.March 1982. ject,Transmission Line Selection Route.

I GLOSSARY Absorption Capability -A measure of the natural sensitivity of a landscape to alteration.Factors such as the potential for human experience,compatible site relationships,and aesthetic values are commonly considered. Aesthetic Value -A measure of the relative overall importance of the visual landscape,including such components as distinctive- ness,uniqueness,harmony and balance. Compatible - A relationship between the existing landscape and man- made features in which the proposed elements are designed in fit- ness with the character of the existing landscape. Distinctiveness -A measure of the visual impression of an area;a landscape where landforms,waterforms,rocks,vegetative or soil patterns are of outstanding and memorable visual quality. Harmony and Balance -A measure of the degree to which all elements of the landscape form a unified composition.This includes the level of integration of man-made elements in a natural setting. Landscape Character Type (LeT)-Landscape Character Types are a description and classification of coherent units of the landscape which are used as a frame of reference to classify the physical features of an area.They are,for the most part,based on physiographic units,and represent land areas with common distin- guishing visual characteristics such as landform,geologic forma- tion,waterform and vegetation pattern. Observer Position -The location or point from where an individual views the landscape. View Duration -The length of time an individual views the land- scape from a particular position. Rarity -A measure of the relative scarcity or commonality of the landscape.Due to Alaska's vast and numerous high-quality land- scapes,rarity will have two levels of meaning for the purpose of thi s report.

Since the 1940s,the Susitna River has been considered for hydropower development and several prel imi nary pl ans for such development have been prepared (see Figure E.9.1).Proposals prior to 1980,which in- cl uded one to four reservoi rs,did not proceed beyond the pre-feas i- bility analysis stage.The present project is located in the Middle Susitna Basin and focuses on a two-dam development:one at Devil Canyon and one near Tsusena Creek (Watana damsite).These.two struc- tures would create elongated reservoirs 0.5 to 1 mile (0.8 to 1.6 km) wide,except for a portion of the Watana reservoir,which woul d be 5 miles (8 km)wide. Land use activity and development within the project area has been minimal.Historical land use activity has been hunting,fishing and trapping.Land use development has been related mainly to hunting and fishing activities. Summaries resulting from land use analysis have been presented pre- viously in Alaska Power Authority,Susitna Hydroelectric Project,Envi- ronmental Studies Subtask 7.07:Land Use Analysis,Phase I Report, April 1982. 1.1 -Purpose and Approach 1.1.1 -Objectives The land use analysis includes an evaluation of the changes "in 1and use 1i kely to be caused by the project and provides the basi s for summari zing the overall land use impacts of the proj- ect.The ana lys is was desi gned to provi de basel i ne data and an impact assessment to: E-9-1 1.1 -Purpose and Approach -Describe past,present,and future land use; -Ident ify potent i a 1 changes in 1and use result i ng from the development of the project;. Describe past,present,and potential future land status; -Identify potential changes in land status resulting from the project development; -Evaluate the project1s impacts on land use and land status; and -Identify mitigative measures to minimize impacts. The scope of work is temporally limited from 1940 to present and geographically by study area boundaries established during the first year of the analysis (Chapter 1 of Exhibit E). The land use analysis descr"ibes and evaluates land development, dispersed use activities and land management.It does not gener- ate data concerning the use of the land by various animal species,nor does it include other detailed descriptions of the physical environment.Information on these subjects is provided in Chapters 3 and 6 of Exhibit E. 1.1.2 -General Discussion of Land Use Evaluation Procedures Present land use development in the Susitna Project area is subtle and widely dispersed.Aerial photographs and topographic maps were used to locate cultural features such as trails,struc- tures,and other indications of past and present land use.An oral history technique was employed to aid in identifying present dispersed land use activities.Present patterns of human land use within the project area and the forces that created different types of use were evaluated.Aerial and ground surveys verified many of the present land use patterns discernible from the oral history interviews. The land use analysis is divided into two parts:historic and existing land use,and future land use.Land use during these periods is described by summarizing acquisistion and settlement, land management,and the use or alteration of specific resources. Three categories were considered when analyzing land use change: 1)dispersed and isolated non-site-specific activity;2)land use inherently associated with site-specific activity;and 3)re- source management. E-9-2 ~, - ..... .- - 1".2 -Summary of Current Land st atus Issues in the Project Area Dispersed and isolated non-site-specific activity includes patterns of activity that are generally non-contiguous and do not involve a commitment of resources at any particular site.These include consumptive,recreational,or subsistence activity such as hunting and fishing;and dispersed activity such as camping, hiking,and photography. Land use inherently associated with site-specific activity in- cludes that involving some form of long-term development or other commitment of resources.These include residences,commercial properties (primarily recreational),mi ning,agriculture,and trans portat ion. Resource management involves consideration of present and pro- posed land management plans developed by agencies with existing or pending jurisdiction.Examples are fish and wildlife manage- ment,dispersed recreation management,and off-road ve~icle man- agement prepared by federal,state,or local agencies,or Native corporations.Native claims,land values,and status of land ownership were al so considered during land use analysis. 1.2 -Summary of Current Land Status Issues in the Project Area The 1 and status in the project area is compl ex.Most of the 1 and in the Susitna drainage area is owned by the Bureau of Land Management (BLM).There are two state land disposal areas west of the project, and small,private parcels,and Native-conveyed land in the project area.The Alaska Statehood Act of 1958 and the Alaska Native Claims Settlement Act of 1971 (ANCSA)withdrew the land in the project vici- nity from development and acquisition.The Statehood Act authorized the state to select 100 million acres (40 million ha)of federal land in Alaska.These land selections triggered Alaska Native protests over the land selections.The resolution of the dispute over possessory rights of the Alaska Natives was the enactment of ANCSA (Price 1982). Under ANCSA,the Al aska Natives received over 40 mill ion acres (16 mill ion ha)of land and approximately $1 bill ion.Furthermore,the Alaska Native villages were required to incorporate under state <law. Most of the 1ands in the dam and impoundment vi ci nity have been withdrawn for Native and state selection (Arnold 1978). The Cook Inlet Region,Inc.(CIR 1)and associated vill age co rporat ions have selected lands along the river.Some lands along the river have been conveyed from the BLM to CIR!,and are subject to Section 24 of the Federal Power Act. The state also selected land along the Susitna River.State selection has been suspended until the Native corporations complete their selec- tion.Upon conveyance of Native selections,the state will assume the remaining selected lands for its selection allotment. E-9-3 1.3 -Summary of Land Use in the Project Area 1.3.1 -Historical Land Use The magnitude,isolation,and location of the Susitna project area in a subarctic environment result in extremely low-density land use.Historical artifacts are of great significance for the overall characterization of activities within a certain time period and geographic location.Their existence indicates explicit human activity and provides a clear description of the basic activity carried on by man in that area. Historical artifacts which were identified to describe past activities included manmade objects used in the project area be- tween 1940 and 1980.Information relating general location and use to each existing artifact was reported by oral history inter- viewees directly associated with the project area,current-day users of the project area,and researchers working at speci fic project area locations.All reported artifacts were located and verified in the field and were used to identify previous land use in the project area.Historical artifacts found within the proj- ect area were 1)structures,which include cabins,cabin founda- tions,food caches,lean-to's,storage sheds,buildings,lodges, and tent platforms;2)roads,trails,airstrips;and 3)other objects,such as abandoned vehicles,bridges,etc. Structures are associated with activities such as hunting,fish- i ng,trappi ng,food or equi pment storage,research,recreat ion (such as skiing,swimming,and photography),and mining.Basic categories covering the frequency in which the existing struc- tures were used consist of:1)no use;2)past seasonal use;3) past and present seasonal use;4)past year-round use;5)past and present year-round use;and 6)no use information. Most of the historical artifacts are associated with some means of access.Unpaved roads and trails were used for access to and from certain points in the project area.Horses,as well as vehicles such as tracked vehicles,four-wheel drive vehicles, rolligons,and dog sleds were used for freighting,for transpor- tation within the area,and for access to the project area.Air- strips on gravel bars or flat ground were commonly located in the proximity of other historical artifacts such as cabins,trails, or lodges.Trails emanate from existing structures and connect with airstrips,lakes (on which ski or floatplanes landed),fish- ing streams,or another structure. A review of the historical artifacts reveals that they were sparsely di stri buted throughout the project area and used on a seasonal basis.The majority of the artifacts were used for hunting,fishing,trapping,boating,mining,or other general recreation purposes,such as cross-country skiing or photography. E-9-4 r"""---" 1.4 -Summary of Land Use Management Planning in the Project Area ..... The artifacts were most densely located near the aggregations of lakes that are accessible by air. Details of historical land use in the project area are presented in the Alaska Power Authority,Susitna Hydroelectric Project, Environmental Studies,Subtask 7.07,Land Use Analysis,Phase I Report,April 1982. 1.3.2 -Existing Land Use Existing land use activity and development has evolved from the utilization of the resource base as a source of income,food, shelter,and recreation.As in the past,access continues to determine the types and levels of land use in the Middle Susitna River Basin.Trails represent environmental modifications and reflect general use patterns. (a)Land Use Activity r-Existing use patterns have been identified for hunting, fishing,trapping,mining,recreation,and hydroelectric research.Access is by means of road,trails,waterways or air.The most intensive activity is .concentrated along the Denali Highway and at established lodges and cabins. (b)Land Use Development - - Developments typically include small clusters of cabins. There are approximately 109 structures within 18 miles (30 km)of the Susitna Ri ver between Gol d Creek and the Tyone River,including four lodges involving 21 structures. Concentrations of residences,cabins,or other structures are near Otter Lake,Portage Creek,High Lake,Gold Creel, Chuni 1 na Creek,Stephan Lake,Cl arence Lake,and Bi g Lake. Some sections of the transmission corridor,particularly near the Alaska Railroad and Parks Highway,include land developments;other sections have virtually no developed land use.. The greatest concentrations of development are in the Stephan Lake area (13 cabins,one lodge,outbuildings,and airstrip)and the Portage Creek m"ining area (19 cabins and related buildings).Chunilna Creek and Gold Creek alsu have some mining development.Three commercial lodge operations are located at High,Tsusena,and Stephan lakes. 1.4 -Summary of Land Use Management Planning in the Project Area There has been little land management, and there are no definitive com- prehensi ve 1and use plans in effect for the p roj ect a rea.The state E-9-5 1.5 -Summary of Major Anticipated Land Use Changes and Mat-Su Borough have initiated preliminary resource studies that serve as the basis for policy development. 1.5 -Summary of Major Anticipated Land Use Changes The construction of a two-dam hydroelectric project,access transporta- tion system,transmission facilities,construction camps and villages, recreation facilities,and other components is a major development, especially in a wilderness area.It will create developed areas, increase access and activity patterns,effect transfer of land owner- ship,and redirect land management. 1.5.1 -Land Status The proposed project will be located in areas involving signifi- cant amounts of Native and state selected lands.Implementation of the project will require purchasing or obtaining rights-of-way to project lands.Increased land management will be required to respond to increased use. 1.5.2 -Land Use Activity The project will result in significant increases in activity pat- terns in the middle Susitna Basin involving hunting,fishing, camping,boating,and dispersed recreation.Persons who current- ly use the Middle Susitna Basin will have to adjust to the in- creased use or move to other areas. 1.5.3 -Land Use Development The project will result in removal of ten structures in the impoundment areas.Construction and emplacement of facilities will involve conversion of land to project use. Significant impacts involve the loss of Devil Canyon and Deadman Falls,and considerable surface disturbanc;e resulting from con- struction activities.The remote character of many areas will diminish with the installation of large-scale,man-made facili- ties.The access road will pass within 1.5 miles (2.5 km)of a remote wilderness lodge on the shores of High Lake. Some negative impacts can be reduced through careful placement of project facilities and the rehabilitation of disturbed surface areas.Policies to control the extent and location of use can be instituted to minimize and confine negative impacts resulting from increased access. Assessment of project construction and operation impacts involves comparison of the potential direct and induced changes in land use with the land use patterns likely to evolve in the E-9-6 fAIWI/I. - -I I 1.5 -Summary of Major Anticipated Land Use Changes absence of any project.Making a definitive forecast of future 1and use for the project area is affected by many factors. including: -Subtle and dispersed land use patterns; -Little active land management;there are no comprehensive man- agement plans that would indicate future use; -Unresolved questions of land ownership and tenure:federal and state agencies and Native groups are presently involved in a process of selection and transfer of lands;and -Minimal land use activity due to the remoteness of the area. E-9-7 ,..,. - 2 -DESCRIPTION OF EXISTING LAND USE 2.1 -Description of Existing Land Status in the Project Area The procedures for land acquisition in Alaska are complex,as illus- trated in Figure E.9.2. Table E.9.1 displays various land holdings in the vicinity of the proposed project impoundment area,and Table E.9.2 summarizes those holdings by status/ownership category. Figure E.9.3 illustrates the land status in the impoundment area. Figure E.9.4 illustrates the land status in the vicinity of the Anchorage-Willow transmission line.Figures E.9.5 and E.9.6 illustrate the land status of the Healy -Fairbanks transmission line vicinity. The following definitions of land classifications pertain to the lands within the vicinity of the Susitna project. Federal:Lands under jurisdiction of the BLM.the Alaska Railroad.or the U.S.Department of Army or Air Force. Native Allotments:Native individuals were allowed by the Native Allotment Act of 1906 to file for allotments of up to 160 acres on unoccupied federal land. State Selected:The state receives land from the federal government in a three-step process.The state first applies to the BLM for land that becomes classified as state selected. State Selection Tentatively Approved or State T.A.:State selected land approved by the federal government for transference to the state. State Selection Patented:Federal lands conveyed to the state. Once patented,the state of Alaska will classify land in one of the following classifications to identify its resource value. Agricultural Commerical Forest Grazi ng Greenbelt Industri a1 Material Mineral Private Recreation Public Recreation Reserved Use Residential Resource Assessment Resource Management Util ity Watershed Wildlife Habitat Unclassified - Land may be reclassified or declassified if a new land use plan.or an amendment to the original land use ~an.determines that such action is appropri ate. E-9-9 2.1 -Description of Existing Land Status in the Project Area The following classifications have been made in the vicinity of the project,including the transmission lines. -Private Recreation Land:Land classified as private recreation because its rural 1 ocati on,physical features,or adjacent develop- ment is suitable for private,low-density recreational development. No land may be classified private recreation until present and poten- tial public recreation needs in the area have been considered.Pri- vate recreation land is available for mineral leasing,sale,lease, or disposal,including remote parcel disposal. -Agricultural Land:Land classified as agricultural because its loca- tion,physical features,and climate may be suitable for agric~tural use.Agricultural land is available for mineral leasing,disposal of materials and timber,and for sale or lease of agricultural rights to private individual s for agricultural use.Each agricultural parcel has a 5 acre homesite available for patent. -Material Land:Land classified as material land is most appropriate- ly used for the extraction of materials such as sand,gravel or stone,and where the removal of the material would prevent other use. Material land may be used for purposes other than the extraction of material s if such uses are compat ibl e with the primary use..The area must be restored to a condition compatible with adjacent uses once material removal is complete.Material land is not available for disposal. -Resource Management Land:Land classified resource management is an area identified as containing surface or subsurface resources (i .e., minerals,timber)that are especially suited to multiple-use manage- ment.Resource management land is not available for disposal. -Utility Land:Land classified utility does not lend itself to clas- sification under other categories because of small or irregular tract size or because its proposed use is not covered under other cate- gories.Utility land is available for lease and disposal. -Unclassified Land:Unclassified land is available for mineral leas- ing,the acquisition of rights to locatable m-inerals,the limited disposal of material and timber,the lease of small scale right-of- ways,and municipal selection. Borough or Municipality Approved or Patented:If state patented land is vacant,unappropriated,or unreserved for a particular use,a borough or a municipality can select the land until it fulfills its entitlement through a process similar to that used by the state in selecting federal lands.Borough or municipal selections can be made from utility or unclassified land.State classification is inapplic- able upon conveyance. E-9-10 ,.- ,, - ""'", r - 2.1 -Description of Existing Land Status in the Project Area State Selection Suspended:Due to the conditions in land status in south-central Alaska,some state selections in the project vicinity were suspended until lands selected by Natives have been conveyed under the provision of ANCSA.The Cook Inlet Land Exchange,Public Law 94-204,has an extensive Terms and Conditions document which allows the state to acquire previously selected land after the conveyance of corporation selected lands to CIRI. Regional Corporation Selection:Lands selected by the regional corpor- ations under provisions of ANCSA are selected similarly to those by the state. Region Corporation Selection Patented:Federal lands conveyed to the corporation.Interim conveyance is allocated to the corporation if the selected lands have not been surveyed. Village Selection:Federal lands selected by Alaskan Natives,under provisions of the ANCSA.The 1 ands have traditionally been used for their commercial resource value and subsistence hunting and fishing. Most village corporations select land near villages or along rivers. The village receives the surface rights and the regional corporation receives the subsurface rights. Village Selection Patented:Village selection conveyed to the village corporation by the BLM.Interim conveyance is allocated to the corpor- ation if the selected lands have not been surveyed. Village corporations in the Cook Inlet Region receive village-selected land by reconveyance from the regiona,l corporation,not the BLM.The procedure for conveyance and reconveyance in the Cook Inl et Region is exceptional to ANCSA.Normal proce.dures are that the region and vil- 1age corporat ions sel ect preferred 1and and the BLM conveys 1 and di r- ectly to the corporation. By 1971,land in the Cook Inlet region had been patented to such an extent that the Native corporations could not select their allocation of usable lands within a BLM requirement of contiguity.The BLM clas- sifies these lands the Talkeetna Mountain Deficiency Lands. Public law 94-456 allows the CIRI corporations to select land in a checkerboard pattern.The BLM will convey a contiguous land selection to CIRI and CIRI will reconvey the alloted lands selected by the vil- lages. The BLM had owned all the land in the project area except for some small private parcels.Mining claims for placer mining presently occur primari lyon federal and state 1and near Ester.Three low to medi um density mining areas are in the project impoundment vicinity.Private parcels occur near Healy at the south end of the corridor,and in the vicinity of Ferry,Nenana,and along Ester Creek in a mining district at the north end of the Healy-Fairbanks transmission route. E-9-11 2.1 -Description of Existing Land Status in the Project Area State selection suspended land exists above and below the Native selec- tion along the Susitna River. The Devil Canyon and a portion of the Watana impoundment areas 1 ie within the boundaries of CIRI selected land.Portage Creek,Stephan and Fog Lakes are also within CIRI selection.Other Native regional corporation selections include land in the Cantwell vicinity selected by Ahtna,Inc.,and Doyon,Ltd.selected land in the Healy-Fairbanks transmission 1 ine route. The BLM has i nteriml y conveyed to eIR I some secti ons adjacent to the Susitna River.Part of these lands,however,have been filed as valu- able lands to the United States for water-power sites.Therefore,the secti ons of 1and withi n the proj ect impoundment area that have been conveyed to e IR I are subj ect to the reservations of Section 24 of the Federal Power Act.The land is open for entry and selection as a power site and will not be destroyed for use as a power site by the owner. No claim to compensation shall accrue from the occupation of the land by the owners.Payment of damages to land use improvements wi 11 be made to the owner in the case the site is selected for water-power de- velopment.Controversy exists about the interpretation of the rights of the landowner and of the water-power license under Section 24 of the Federal Power Act. The Watana-Devil Canyon access road traverses the state 1 ands and Native selected land.The Denali Highway -Watana access road tra- verses across BLM land.The Denali Highway from Cantwell to the access road intersection traverses across state selection patented or tenta- tively approved land,and Native village and regional selected land. The Indian River Subdivision and Remote Parcel are private recreational land west of the project impoundment area north of the Susitna River. The Indian River Subdivision (T33N,R2W,Seward Meridian)lies near mile 168 of the Parks Highway,northwest of Chulitna Butte.The dispo- sal area has been subdivided into roads and 139 lots averaging 5 acres (2 ha)per lot.The Indian Ri ver Remote Parcel,located northeast of the confluence of the Susitna and Indian Rivers,is south of the Indian River Subdivision.This remote parcel (T31-32N,R2W S.M.)is located east of,and adjacent to,Denal i State Park.The Indian Ri ver Remote Parcel will be divided into 75 parcels. The Willow -Anchorage transmission corridor extends across Fort Richardson Military Reserve for 18 miles (29 km),then across the muni- cipal ity of Anchorage patented and selected lands,and Matanuska - Susitna Borough property located approximately 10 miles (16 km)north of Anchorage and east of Kni k Arm.The Sus itna Fl ats State Game Refuge is resource management land within the Anchorage -Willow transmission route.The predominant resources identified are public recreation and wildlife habitat.Approximately 5 miles (8 km)of the line will tra- verse across the Point MacKenzie agricultural sale property.The re- mainder of the transmission line route extends across state land E-9-12 ""'" I""'" I ..... .J"- I ,... i ,... 2.2 -Description of Existing Land Use in the Project Area until the vicinity of Willow.At Willow the study area encompasses Holstein Heights Subdivision,state private recreation land in Section 20,Township 15 North,Range 4 west of the Seward Meridan (see Fi gure E.9.10).Private land is interspersed with Mat-Su Borough selected land.The selection of the proposed route avoided private lands to minimize the impact of the line to residents (see Figure E.9.4). The Healy-Fairbanks transmission corridor traverses the U.S.Air Force Clear M.E.W.S.Military Reserve land for approximately 10 miles (16 km) in the vici nity of Anderson.The ltne extends across state sel ected land,much of which has been patented or tentatively approved.The transmission route between Healy and Fairbanks will pass the Keystone Extension (Section 10,T1S,R2W,FM),Alder View (Section 21,T1S,R3W, FM),Healy Small Tracts (Section 12,T1S,R8W,FM),and Northridge Sub- divisions (Section 17,TlS,R2W,FM)on the west side of the Parks Highway.The proposed line will parallel an existing transmission line when traversing these private recreation disposal areas.Numerous material land sites are located within the Healy-Fairbanks transmission line route.The Healy-to-Fairbanks transmission route extends across Fai rbanks North Star Borough sel ected 1and at the north end of the corridor (see Figure E.9.5 and E.9.6).A number of proposed land dis- posal areas exist along the transmission corridor.The exact location, future status,and potential for impact of these areas is being dis- cussed with the Al aska Department of Natural Resources. Existing values for land required for project use have not been es- tabl i shed by any federal,state or Nat ive agency.State 1and di sposal s have been acqui red privately by lottery.The right-of-way for the Alaska Power Authority's Willow-Healy transmission intertie line has been appraised.Land value of the proposed transmission routes may be similar where adjacent to that route and higher as the proposed routes encroach upon the increased land use development and management of Anchorage and Fairbanks. 2.2 -Description of Existing Land Use in the Project Area 2.2.1 -Description of Land Use Evaluation Procedures Specific procedures and steps involved in the land use analysis are discussed below. (a)Study Areas Based upon preliminary project descriptions,three study areas (Zones 1,2,and 3)were defined fo~existing land use analysis (Figure E.9.7).These zones were designated according to geographic and land use relationships with the proposed project and extend in varyi ng wi dths from the - Susitna River between the mouth of the Tyone River and Gold Creek. E-9-13 2.2 -Description of Existing Land Use in the Project Area Zone 1 includes those structures and land uses that would be affected by inundation.Zone 2,extending about 6 miles (10 km)from Zone 1,is based upon the 1 ocat i on of 1 akes which characterize aggregations of land use.Zone 3,ex- tending approximately 12 miles (20 km)beyond Zone 2,is distinguished by fewer aggregations of land use;existing structures and land use are sparse.In addition to an assessment of the effects of the dams and impoundments and closely related facilities,the land use analysis also in- volved evaluating the impacts of the transmission line routes.To investigate these concerns the transmission corridors between Anchorage and Willow and between Healy and Fairbanks were analyzed. (b)Literatu re Revi ew A general 1 iterature search was initially conducted to determi ne what 1 and use and resource management mi ght be expected in the project area.The search included a review of available public and private agency planning documents, historic accounts of the area,and any specific historical documents.As they became available,additional private and publ i c agency documents were acqui red and researched. (c)Aerial Photography and Map Reconnaissance Aerial photographs and topographic maps were used to locate certain cultural features such as trails,habitations,and other indications of past and present land use.Old maps from historical texts and early geological surveys were reviewed for foot and sled trails and for mining sites. Maps available at the University of Alaska library and museum and from the U.S.Geological Survey were reviewed for indications of past land use.Agency maps and aerial photos were examined to obtain information concerning all- terrain vehicle (ATV)access,tractor trails,roads,landing strips,and guide camp locations. (d)Interviews Two types of interviewing were used.Oral history inter- viewing was undertaken,to reconstruct a land and resource use history of the Middle Susitna Basin.This history focuses primarily on the area surrounding the Susitna River between Gold Creek and the Denali Highway,where the pro- posed project would be located.Consideration of adjacent areas was necessary,however,to put the history of the pro- ject area into perspective.The interviews were nondi- rected,in that,whi 1e there was speci fi c format and data needs,the interview was conducted so as to appear informal E-9-14 r--,.-;--, ,.- I, .... I 2.2 -Description of Existing Land Use in the Project Area to the respondent.The interview process and a list of interviewees are available in Subtask 7.07 of Alaska Power Authority,Susitna Hydroelectric Project,Environmental Studi es,Phase I Report,1982. A second type of interviewing was designed to seek informa- tion from land management agencies concerning present land use,current management direction,and alternative future management strategies,depending upon whether or not the Susitna Hydroelectric Project is built.Management agencies contacted and the questions asked of agency personnel are available in Subtask 7.07 referenced above.Additional contacts with agencies have been made during the course of the study to provide for exchange of information and data. -. ! .... ..... (e) (f) Field Reconnaissance Field surveys permitted existing land use data to be certi- fied and refined by locating,mapping,inspecting,and photographing the historical artifacts reported during the interviews.Field surveys were approached from a dual per- spective:by aerial surveys and by ground verification sur- veys.Field surveys in proposed development locations were employed to locate important natural features and to esti- mate potential impacts on the area1s resources • Aerial surveys accounted for the macroscopic verification (geographic location)of the reported historical artifacts and use information.Once located,these artifacts were recorded,mapped,and photographed.Information from aerial surveys was also used as a basis for establishing priorities for ground truthi ng.These priorit ies were based on sites of historic interest and sites for which limited information was avai 1abl e. Compilation of Land Use Inventory Land use data were summarized both chronologically and geo- graphically.Since land use was analyzed within a temporal as well as a geographic context,time cut-offs and zone boundaries were established for analysis and expression of data.The data were summarized by decade and then analyzed according to a combined geographic time period interaction to detect any major data gaps. Information concerning existing land uses,dispersed use activity,land status and owrership patterns,and management activity was summarized. E-9-15 2.2 -Description of Existing Land Use in the Project Area (g)Access Road and Transmission Line Analyses Land use was a consideration in the evaluation of alterna- tive routes for the access road and selection of the recom- mended corridor and route for transmission 1ines.Tech- niques specific to these project components were employed both in the selection process and in the impact assessment for the proposed routes. (h)Project Impact Assessment Various project facilities were assessed to identify changes in basel"ine land use likely to occur as a result of the project.Impacts were determined by making qualitative and quantitative estimates of the potential changes in the base- line 1and use. (i)Mitigation Mitigative measures that would minimize project impacts were identified.In some cases,project impacts have been re- duced through selection of destgn options having less impact than others.Where this was not possible,mitigative pro- posals have been identified for consideration in subsequent planning and design refinement. 2.2.2 -Existing Land Use Activity Figure E.9.8 identifies the location of land use aggregations for recreation,mining,and residential activities,and quantifies the intensity of use. Low intensity areas contain one dwelling or less per acre. Medium intensity designates a concentration of two to four dwell- ings per acre.High intensity areas support five or more dwell- ings per acre (ADNR 1980). (a)Zone 1 Little activity in the way of trapping and mlnlng currently takes place in Zone 1,especially compared to those pursuits in Zone 2 and Zone 3.Although hunting is also less common in this zone than in either of the other two,some hunting does occur.especially from tent camps. E-9-16 2.2 -Description of Existing Land Use in the Project Area River-related activities include river boating and floating • .Boating within the·project area has been linked with research,fishing,and recreation.Raft float trips are taken from the Denali Highway on the Susitna or Tyone Rivers down to above either Vee or Devil Canyons. Another Zone 1 activity involves hydroelectric research. Following preliminary studies,the Bureau of Reclamation proposed in 1952 that the Susitna be considered for poten- tial hydroelectric development.Since then,there have been many feasibility,design,and environmental studies of the proposed i nundati on zone and adjacent areas.These studi es combined most likely have contributed more total man-days of use in the area in the past twenty years than all other uses. (b)Zone 2 and Zone 3 Zone 2 is the area extending about 6 miles (10 km)from Zone 1.Thus,Zone 2 encompasses the area downstream from Devil Canyon,including the river.Some significant activity occurs along the river in this region.Salmon fishing represents an important activity in this part of Zone 2 since salmon are found to migrate up the Susitna as far:-as I"""Devil Canyon.Individual and ri verboat operations out of Tal keetna travel up the Susitna Ri ver,offering services that include day trips to Devil Canyon;drops at camps for hunting,fishing,and photography;and canoe hauls to many tributaries.Some canoeing and rafting takes place from just below Devi 1 Canyon to Tal keetna.Some canoe enthu- si asts portage between the 1 akes in the Stephan Lake vi c i- nity and canoe to Talkeetna via Prairie Creek and the Talkeetna River. (i)Hunting i~ ,... I ..... Lodges typically handle 15 to 25 guests at a time and about 140 guests per season.The increasing popular- ity of sport hunting in the 1960s caused an increase in the number of small cabins on many of the lakes in the project area.Both guided and non-guided hunting occur within the project area,particularly near Stephan,Fog,Cl arence,Watana,Deadman,Tsusena,and Big Lakes,in addition to many of the area's smaller lakes.Both lodges and cabins provide the field bases for many hunters. E-9-17 2.2 -Description of Existing Land Use in the Project Area (ii)Fishing Fishing in the project area occurs either as a sep- arate pursuit or in close association with other activities,such as hunting and trapping.Fish pre- sent in the area's lakes and streams include burbot, grayling,rainbow trout,Dolly Varden,lake trout, and whitefish.Considerable fishing for lake trout, grayl ing,and salmon occurs in the Stephan Lake - Prairie Creek drainage.Salmon fishing occurs in lower Portage and Chunilna Creeks and Indian River. Fishing in Fog,Clarence,Watana,Tsusena,Deadman, Big,and High Lakes appears to be associated with other activities,such as hunting,summer cabin use, and mining.There is little stream fishing elsewhere in the project area. (iii)Trapping Present trapping in the project area occurs mostly on the south side of the Susitna River near Stephan and Fog Lakes.Some trappi ng al so occurs near Tsusena Creek and Cl arence and High Lakes.Traps are set sporadically by aerial trappers in the easternmost portions of the Susitna valley. (iv)Mining Mineral exploration and mlnlng have been limited in the immediate project area.Mining in the Upper and Middle Susitna River Basin has been low in claims dens ity and characteri zed by intermittent act iv ity since the 1930s.Placer mines working alluvial deposits for minerals are found in sites throughout Mat-Su Borough.Active mining has been more concen- trated in Gold,Chunilna,and Portage Creeks than in areas of the Upper Susitna Basin.Other active claims are around Stephan and Fog Lakes,Jay Creek, and the Watana Hills east of Jay Creek. Coal is the major mineral resource in Mat-Su Borough. Extensive coal deposits occur in the Beluga area.No coal mining activity occurs in the project area. 2.2.3 -Existing Land Use Development In both the past and present,the sparsely distributed develop- ments throughout the project area have been used predominantly on a seasonal basis.The majority of the land use development or E-9-18 - 1""" I 2.2 -Description of Existing Land Use in the Project Area artifacts has been utilized for hunting,fishing,trapping,boat- ing,mining,and other general recreation purposes,such as cross-country skiing or photography.Existing structures in the project area are shown in Figure E.9.9,and Table E.9.5.Land use development of the Anchorage-Willow and Healy-Fairbanks transmission lines is illustrated in Figures E.9.10,E.9.11,and E.9.12 .. (a)Zone 1 Types of developments located in Zone 1,the inundation zone plus 200 feet (61 m),include structures,trails,and air- strips. Ten isolated structures are located in Zone 1 on the shores of the river or on its steep banks.Of these structures, only three are mai ntained and then only used on a seasonal basis.Two others,though not actively maintained,appear to be used sporadically by transient hunters,fishermen,or boaters.The remainder are not currently usable. (b)Zone 2 The greatest number of existing land use development and historical artifacts are located in Zone 2,which is a much smaller area than Zone 3.Types of development found in Zone 2 include structures,trails,roads,airstrips,and mines.General types of use associated with these artifacts consist of hunting,trapping,fishing,boating,mining, recreation,and research. Although the primary distribution of use throughout the pro- ject area is low density,the aggregations of existing de- velopment are particularly noteworthy.The nuclei of these aggregations are the small lakes and lake systems located throughout Zone 2 that provide access by air.The aggrega- tions of development consist of cabins and related struc- tures,lodges,roads,trails,and airstrips. - - (c)Zone 3 Fourteen of the 25 existing structures in Zone 3 are cur- rently used during some portion of the year.Aggregations of use occur in the areas of Chunilna and Prairie Creeks south of the project area. Structures,use types,and access are categorized by land use zones and are summarized in Table E.9.3.The maJor trails into the project area represent substantial environ- mental modifications and reflect general use patterns;they are presented in Table E.9.4. £-9-19 2.2 -Description of Existing Land Use in the Project Area Land use east of Ta 1 keetna and Cha se is domi nated by the land disposals along the Talkeetna River.Parcels within the Talkeetna Agricultural Disposal are available for agricultural use.A few homesteads exist around Larson Lake,east of Talkeetna.The Larson Lake residents could develop the lake for residential recreation.There are five landing strips in the Talkeetna area;two within the village of Talkeetna which are registered public landing strips. Residential and commercial land development occurs west of Curry Ri dge and along Petersville Road near Trapper Creek. There is some scattered residential land use along the Parks Highway and Chulitna River within Denali State Park.The areas of principal concentration are where residents desire to keep the land in a natural,pristine condition.Within the Curry area is Byers Lake State Campground,whi ch con- tains hiking trails to Curry Ridge and Troublesome Creek. Land use development east of Curry Ridge along the Alaska Ra i 1 road i ncl udes the Indi an Ri ver Land Di sposal and the Indian River Remote Parcel.Both are recreation oriented. The disposal is surveyed into 5-acre (2-ha)lots having util ity easements.Only a 1 imited amount of residents remain the year round.The disposal is within the Talkeetna Mountains Special Use District,which requires the residents to get a permit before constructing a dwelling.The Remote Parcel will have a specific number of residents able to obtai n lots rangi ng between 5 and 40 acres (2 and 16 ha). Homesteads occur along the Alaska Railroad at Chulitna,Gold Creek,and the Susitna and Indi an Ri vers.There are two private landing strips at Gol d Creek,one at Curry and Chul itna. Land use development between the Mi ddl e Fork and Ea st Fo rk of the Chul itna Ri ver and along the Chul itna Ri ver is limited to a few residences on the Parks Highway. Residential and commercial land use development has become established at Cantwell,Summit and Broad Pass.Land use development such as the Cantwell Community Center is ex- pected to continue along the Denali Highway.The Golden North Airport is situated east of Cantwell along the Denali Highway and is a registered public airport.There are two other landing strips in the Summit area.Al so present are the Parks Highway,the Alaska railroad,and the eastern boundary of Denali National Park and Preserve. E-9-20 - ..- 2.2 -Description of Existing Land Use in the Project Area Residential and commercial land use developments exist along the Nenana Ri ver and the Parks Highway near the Denal i National Park and Preserve and prior to entering the Nenana Gorge.The Alaska Railroad and the Parks Highway wind through the gorge.There is residential and commercial land use around the Healy Generating Station.Other developed land use near the northern transmission corridor is low den- sity residential with travel-oriented commercial develop- ments located along the Parks Highway.Two private landing strips are located in Healy. 2.2.4 -Special Lands (a)Wetlands Proposed land use development is contingent on wetland and floodland locations.Potential wetlands cover large por- tions of the Middle Susitna River Basin,including riparian zones along the mai nstem Susitna,sloughs,and tri butary streams,and numerous lakes and ponds on upland plateaus. f"""In addition,extens i ve areas of wet sedge-g rass tundra are classified as wetlands by the U.S.Army Corps of Engineers for purposes of Section 404 permitting.Wetland areas of particular importance in the project area include Brushkana Creek,Upper Deadman Creek,the area between Deadman and Tsusena Creeks,the Fog Lakes area,the Stephan Lake area, Swimming Bear Lake,and Jack Long Creek. - All wetlands within the proposed impact area were classified according to Cowardin et ale (1979)into appropriate wetland classes (Acres/TES 1981)-.Maps delineating wetland types constructed by usi ng the vegetation/habitat maps can be found in Chapter 3 of Exhibit E.This was done with little consideration of soil moisture conditions since this infor- mation was unavailable. Vegetation and wetland classes found in the proposed Susitna project areas are as follows: - ...... Mapping Unit (Viereck &Dyrness 1980) La kes,pond s Ri vers,streams E-9-21 FWS Wetland Class (Cowardin et al;1979) Lacustrine unconsolidated bottom,aquatic bed,un- consolidated shore Riverine Upper Perennial rock bottom,unconsoli- dated bottom,rocky shore,unconsolidated shore 2.2 -Description of Existing Land Use in the Project Area Wet sedge -g ras s Palustrine or Lacustrine emergent Low shrub Palustrine scrub-shrub Birch shrub Palustrine scrub-shrub Willow shrub Palustrine scrub-shrub Open black spruce Pa 1 ustri ne forested Woodland black spruce Palustrine forested Open white spruce Palustrine fo rested Closed white spruce Palustrine forested Open balsam poplar Pal ustrine forested Closed balsam poplar Palustrine forested Wet sedge-grass types dominate half of the tundra.Tundra vegetation/habitat types are generally located above the limit of forests.Approximately 24 percent of the Middle Basin is covered with tundra.The tundra types are charac- teristic of high elevations less than 3200 feet (970 m)and their distribution is associated with the mountains of the Alaska Range and the Talkeetna Mbuntains.Only in the vici- nity of Devil Canyon and Jay Creek are there substantial acreages of tundra in close proximity to the impact areas. Shrubland is the largest overall group of vegetation/habitat types occurring in the Middle Basin.covering almost 40 per- cent of the total area.30 percent of that by shrub birch and wi 11 ow.These types are found at i ntermedi ate and low elevations throughout the basin.primarily on the broad flat areas. Coni fer forests (spruce)cover approximately 19 percent of the Middle and Upper basins.They occupy a wide range of sites.from the floodplains to the mountains.but seldom above the 3200-foot (970-m)elevation.Conifer forests are 25 percent more extensi ve in the impact areas than in the Middle Basin.This is because the impact areas are restricted to lower elevations where conifer forests are located. E-9-22 .- -- - - -. 2.2 -Description of Existing Land Use in the Project Area Balsam poplar is restricted in distribution to less than 2.5 percent of the Middle Basin.This vegetation/habitat type is found below the 2300-foot (697-m)elevation and in the fl oodpl ain.Open and closed bal sam popl ar stands are the predominant vegetation types found on the floodplain down- stream to Talkeetna. The Susitna Hydroelectric Project will require approval from the U.S.Army Corps of Engineers prior to construction. This approval is in the form of permits required by Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act.The purpose of the permit system is to assure that projects will not interfere with navigation and will not unnecessarily pollute waters and wetlands.Land ownership has no bearing on the need for a permit. Federal regulations define wetlands as areas that,under normal circumstances,would support vegetation typically adapted to saturated soils.Approximately one-third of Alaska is wetlands.All wet tundra,and various amounts of other tundra types,are considered wetlands. Where soil is saturated with water,p hotosynt hes is occurs rapidly.Such areas are highly productive biologically and rich in nutrients that support microscopic plants and ani- mals whi-ch are food sources of higher life forms.Wetlands support a greater diversity of wildlife species per unit area than most other habitat types in Alaska.Riparian wet- lands provide winter browse for moose and can be a critical survival factor for this species during severe winters. Wetlands are also important because they help to maintain water quality throughout regional watersheds.' Detailed wetland mapping of much of the state will eventual- ly be completed by the National Wetlands Inventory,con- ducted by the U.S.Fish and Wildlife Service.Aerial photo- graphs,soil maps,topography charts,and field reconnais- sance are presently employed to determine wetland locations (USCOE 1980). A more specific description and maps of the vegetative/habi- tat types and wetlands are found in Chapter 3 of Exhibit E of the Alaska Power Authority's Susitna Hydroelectric Pro- ject application FERC license. The Cowardin system of wetland mapping has been adopted by the U.S.Fish and Wildlife Service,and is acceptable to the U.S.Corps of Engineers for permit applications.Lakes, ponds,rivers,and streams were not specifically classified. E-9-23 2.2 -Description of Existing land Use in the Project Area There is a considerable amount of potential wetlands within the project area.The estimates of total palustrine wetland areas were liberal since the wetlands were highly integrated with non-wetlands and supporting hydro soil data and peri- odic ambient water conditions were not available.Portions of these areas may thus be eliminated by further considera- tions of soil and water conditions. (i)Dams and Impoundments With-in the approximate boundaries of Zone 1,there are potential wetlands of various types,includ-ing riverine.The Watana dam,spillway,and impoundment will cover 26,967 (10,787 ha)acres of potential wet- land types.The Watana camp,village,and airstrip will be on 371 acres (149 ha)of wetlands.The Devil Canyon dam,spillway,and impoundment facilities will cover 4117 acres (1647 ha)of wetland types.The Devil Canyon construction camp and village is not mapped but appears to occupy potential wetland areas. (ii)Access Potential wetlands dominate the access corridor from the Denali Highway south to Watana and then east to Devil Creek.Si xty-one percent of the total access road is Palustrine scrub-shrub wetland type broken only by occasional creek crossings.These potential wetlands are located for 16 miles (26 km)extending south of Denal i Hi ghway and for 30 mil es (50 km) south of Deadman lake (see Figures in Chapter 3 of Ex hi bit E). Twelve percent of the corridor is 50 percent Palus- trine scrub-shrub wetland.This location is west of Devil Creek where Palustrine scrub-shrub wetland pre- dominates.Radiating from this point 4 miles (7 km) east and west along the corridor the Palustrine scrub-shrub wetland wanes to 50 percent. Four percent of the corridor,an area north of Dead- man lake,is 50 percent Palustrine scrub-shrub and 50 percent Palustrine emergent wetland types.As the corridor extends north from Deadman Lake,it becomes 50 percent Pal ustri ne emergent wetl and type only. Seven percent of the corridor is Palustrine emer- gent. E-9-24 - - ,.,... 2.2 -Description of Existing Land Use in the Project Area The corridor south af the Susitna River,predominant- ly the railroad corridor,is within 2miles (3 km)of the river.Isolated areas of Pal ustrine forested wetland types occur in this section of the corridor. It is 16 percent of the total corridor length. - - (iii)Transmission Wet sedge grass and potential wet spruce areas within the Anchorage-Willow and Healty-Fairbanks trans- mission corridors are illustrated in Chapter 3 of Ex hi bit E. Dams to Intertie The central corridor is not separate from that of the dam and impoundment impact area which extends 10 miles (16 km)in all directions from the Middle Susitna River.Palustrine forested is the only wetland type in the central corridor and exists in slopes and benches. -Anchorage-Willow The Anchorage-Willow corridor passes through relatively flat terrain and is approximately 24 percent Palustrine or Lacustrine emergent meadows. -Healy-Fairbanks The southern portion of the Healy-Fairbanks corri- dor has Palustrine forested wetland along the ridges with Palustrine scrub-shrub and Palustrine or Lacustrine emergent wetlands occupying the flat- ter areas.The central corridor segment is covered by a complex mosaic of wet Palustrine forested and Palustrine scrub-shrub wetlands.The gradiation and patches of wetl and types made it necessary to map thi s area as "compl ex."Forested types of wet- lands accounted for 78 percent of this corridor. - (b)Fl oodl and s The National Oceanic and Atmospheric Administration does not have an office of Coastal Zone Management in AI aska.The U.S.Corps of Engineers,Floodplain Management,conducts hydraulic analysis of floodlandsto determine floodplains for the Federal Insurance Program of the Federal Emergency Management Agency (FEMA).Floodplains of interest to the E-9-25 2.2 -Description of Existing Land Use in the Project Area Federal Insurance Program are defined as "the 1 owl and and relatively flat areas adjoining inland and coastal waters, including at a minimum,that area subject to a one percent or greater chance of flooding in a given year"(E.O. 11988).Special area management plans are prepared for FEMA in areas of potential land use develo[Xnent where floodplains .have not been delineated.No such management plans have been prepared in the Middle Susitna Basin due to the remote- ness of the area. A preliminary final Flood Insurance Study,Mat-Su Borough, has been completed by the U.S.Army Corps of Engineers for the Federal Emergency Management Agency.No reference has been given to the Susitna River.Detailed study "included the Little Susitna River,and Disception and Willow Creeks. An approximate study has been made on the Matanuska and Kn"ik Rivers and in the Bodenburg Butte Area. U.S.Corps of Eng ineers has mapped the 100-year flood el eva- tion on the Nenana River at the Community of Nenana and at Chul itna on Pass Creek,a tributary of the Chul itna River. The 100-year fl oodpl ain of the Tal keetna,Susitna and Chul itna River has been mapped within the corporate 1 imits of Talkeetna.The U.S.Geological Survey has tabulated streamflow and suspended sediment data for the Susitna River at Gol d Creek since 1949.The Gol d Creek peak di scharge of record is 90,700 cfs. Talkeetna is subject to flooding from the Talkeetna, Chulitna and Susitna Rivers.The floodplain of the Talkeetna River at Talkeetna is wide and developed only on the south side at the mouth of the river.Open spaces in the flood plain are extensive and may come under pressure for future development.The properties in Tal keetna are primarily resi denti al and commerc i al • The Floodplain Information Report,Talkeetna,Alaska,(U.S. Corps of Engineers 1972)is a basis for the adoption of land use controls to guide floodplain development and prevent intensified loss and damage.Peak discharge for the Inter- mediate Regional Flood,or the 100-year flood,at Talkeetna is 268,000 cfs.Peak discharge for the Standard Project Flood is 315,000 cfs. Figure E.9.13 illustrates the 100-year floodplain on the Susitna River at Talkeetna.The 100-year floodplain between Talkeetna and Devil Canyon based on the 100-year flood discharge at Gold Creek is shown in Chapter 2 of Exhibit E on Figures E.2.l2 through E.2.20.The calculated 100-year flood discharge at Gold Creek is 118,000 cfs.

Management Plans for the Project Area The BLM,the A1 aska Department of Natural Resources,Mat-Su Borough, and CIRI and associated village corporations have various management concerns in the project area. Federal lands to the north of the project area are managed by the BLM (BLM 1982).These lands are included in the Denali Planning Block (Fi gure E.9.14).A Decision Record-dated July 1982,authorized the Dena1i/Tieke1 Amendment to the South-central Management Framework Plan to be a Finding Of No Significant Impact (FONSI).The attachment of A Decision Record authorizes the draft report to be final.The plann- ing blocks address oil and gas,mineral entry,wildlife and scenic values,and settlement/disposal. Management in the Denali Unit and in those areas not yet conveyed to the Natives or the s~ate is essentially passive.Very few management activities are taking place.BLM's objective is to protect the natural environment of the area,with particular attention to caribou calving areas and river recreation routes.Fire control is also a current management consideration.BLM has a cooperative fire control agreement with the state of Alaska that covers the project area. A Denali Scenic Highway Feasibility Study draft report will be avail- able for public review in March 1983.The BLM is the lead agency for the study.Other study participants include the National Park Service, Federal Highway Administration,ADNR,Alaska Department of Transporta- tion and Public Facilities,ADF&G,Ahtna,Inc.,village corporations, and Mat-Su Borough. The Alaska Land Use Council consists of federal and state agency repre- sentatives to oversee jo"int management plans as designated by ~he Alaska National Interest Lands Conservation Act.The Alaska Land Use Council will give its recommendation about the scenic highway proposal E-9-27 2.3 -Description of Existing Land Use Management Plans to the Secretary of the Interior,the President of the United States, and Congress in September,1983. Finally,BLM is also developing a wildlife habitat management plan in cooperation with ADF&G for the Alphabet Hills between the Tyone and Maclaren Rivers (T11-12N,R2-9W,Copper River Meridian).This plan will involve moose habitat manipulation.As yet,however,only study plots for this project have been mapped out. In the project area,the state had,until recently,done only a re- source assessment for those lands it is proposing to select.In 1982, a planning background report was completed with the cooperation of the Mat-Su Borough,Kenai Peninsula Borough,ADF&G,and the Alaska Depart- ment of Transportation and Public Facilities (ADNR 1982).Currently, ADNR's Division of Research and Development is undertaking a comprehen- sive assessment of the resource base in general.The Susitna Area Plan for state land is being developed in cooperation with Mat-Su Borough. A Susitna Area Planning Team is comprised of state resource agencies including all divisions of ADNR,ADF&G,Alaska Department of Transpor- tation and Public Facilities,and Mat-Su Borough.The Susitna Area Planning Team is designated to plan appropriate land use of state and borough lands within Mat-Su Borough.The state has requested coordina- tion between the Susitna Hydroelectric Project and the regional land use plan,specifically in the two following areas: -The planning team can review and comment on information regarding regional,indirect impacts of the plan (i.e.,population growth changes in resource demand,etc.);and -The plan can be used as a tool to guide use of public lands to mitigate or control secondary impacts of the proposed project. The state's primary management goals for state classified land on pro- ject effected land is to: Provi de for p ri vate recreati ona 1 use of ru ra 1 areas by all owi ng p ri- vate recreational development to occur in an orderly fashion; -Preserve agricultural land for either present or future use; -Allow for the sufficient and orderly extraction of materials and to assure restoration compatible with adjacent uses;and -Allow variable management plans to be specified upon resource identi- fication. The Draft Land Use Plan for Public Lands in the Willow Sub-basin (ADNR 1981)identifies future agricultural 1 and sales in the vicinity of Willow and programs for protecting wildlife habitat and sportmen's access.No additional agricultural disposals have been identified for the project area or within the transmission line routes. E-9-28 - 2.3 -Description of Existing Land Use Management Plans Mat-Su Borough is involved in three separate management efforts which affect the project area.These are the Mat-Su Borough Comprehensive Plan (1978),the Talkeetna Mountains Special Use District,and the Mat-Su Borough Coastal Management Program.The current Mat-Su Borough Comprehensive Plan (1978)contains very 1 ittle discussion of the Susitna area lands.The borough has al ready selected more than its entitlement and is concentrating its selection in the Lower Susitna Basin near existing highways.Thus,it is unlikely that the borough will select any lands in the project area. The borough,by ordinance,has created the Talkeetna Mountains Special Use District,through which the borough can exercise planning and per- mitting authority over all lands within the district's boundaries;this special use district includes the project area.The Indian River Sub- division and Remote Parcel are also within the special use district. The Mat-Su Borough plan will allow recreation cabins at these sites but not permanent re?idences. The ord,inance provides for multiple resource use of the district and takes into account u ni que sceni c val ues.Thus,1 ands wi thi n the special use district are subject to permit requirements for specified developments (roads,subdivisions,etc.). The borough is updating its comprehensive plan,and additional studies are currently being performed (Dowl Engineers 1982).The project area is considered a mixed-use zone which would permit hydroelectric devel- opment.Management objectives for the project area will probably not be refined until the current hydroelectric studies are complete. Through a cooperative arrangement with the'Office of Coastal Zone Management (National Oceanic and Atmospheric Administration,U.S. Department of Commerce)and the Al aska Coastal Management Program (Division of Community Planning,Alaska Department of Community and Regional Affairs),IViat-Su Borough is preparing a Coastal Management Program.Preliminary studies were completed in May 1981;originally the Susitna River through Devil Canyon was designated to be within the biophysical boundaries of the program (Figure E.9.15).At present the dam is not included within the program. CIRI received conveyance of selected Native lands to hold in trust until these lands are conveyed to the appropriate villages (Chickaloon- Moose Creek,Tyonek,and Knik).Currently,no land management activi- ties are being carried out.When tne villages obtain their lands,the different v ill age ownersh"j ps will create a checkerboa rd pattern.Imme- diate land problems and land reconveyance to villages are being handled by the Village Deficiency Management Association,a group made up of representat ives from each of the concerned vill ages.Because of the checkerboard pattern of ownershi p descri bed above,.any management of Native lands may be undertaken by this association. E-9-29 - - ,..... - -- - 3 DESCRIPTION OF LAND USE CHANGES RESULTING FROM THE PROJECT Brief descriptions of the major facilities are presented below;details may be found in Exhibit A of the FERC license application for the Susitna Hydroelectric Project. Construction and operation of the dams and related facilities will cause impacts on area resou rces.The development of the two-dam facility,the establishment of the camps and villages and their associated commercial and recreational development,the increased public access into the Susitna Basin,and the improved public recreation potential in the region will escalate the land value in the project area.The increase of adjacent commercial,recreational and residential development will appreciate the value of land belonging to owners along the Parks and Denali Highways.The land value along the transmission line easement will remain unchanged by the existence of the line;however,the resale potential may be limited if adjacent lands of similar value are available for sale. Before determining the extent of the land use changes,land use priori- ties were assessed in terms of land use activity and development verses conservation and preservation of specific ecosystems.In few cases, these resource values are identified in agency management programs that apply to the area.Section 2.3 described the existing land use manage- ment plans;Section 4 discusses the changes in land use management plans resulting from the project. Project facilities will create immediate,direct impacts on the land- scape.Some of these impacts will be temporary,such as the construc- tion camps and construction activity.Other aspects of the project will create permanent and often subtle changes in the type,nature,and intensity of development and activitiy.Chief among these aspects is the provision for automobile access to an area currently remote. 3.1 -Dams and Impoundment Areas 3.1.1 -Proposed Facilities Figure E.9.16 illustrates the location of the proposed facilities in the impoundment area. (a)Watana The Watana Dam will be a 885-foot (270-m)high,gravel- fill structure,with a crest length of 4100 feet (1250 m). The dam will be located at Susitna River mile 184,approxi- mately 2 miles (3 km)upstream from the mouth of Tsusena Creek.It will impound approximately 54 mil es (80 km)of river to the 2185-foot (666-m)elevation and inundate about 38,000 acres (16,000 ha).A general layout of site facili- ties is shown on Figure E.9.17. E-9-31 3.1 -Dams and Impoundment Areas (b)Devil Canyon Devil Canyon Dam will be a 645-foot (197-m),concrete thin- arch dam and a rock-fill ed saddl e dam constructed at ri ver mile 152 in Devil Canyon.Its crest length will be 2475 feet (754 m).The dam will impound miles (42 km)of river to the 1455-foot (444-m)elevation.Approximately 7BOO acres (3157 ha)of land will be inundated.A general layout of site facilities is shown on Figure E.9.IB. 3.1.2 -Induced Land Use Changes (a)Land Use Oevelopment The emplacement of the Watana dam and impoundment will inun- d ate six st ruct u re s•Th es est ruct u res are n um be red 90,91, 92,Ill,112,and 120 on.Figure E.9.9.One structure is ac- tively maintained as indicated in Table E.9.5.Number 90 is a lean-to for hunting and fishing purposes. The emplacement of Devil Canyon Oam and impoundment wi 11 inundate three structures (2,6,and 107),as illustrated in Figure E.9.9.As indicated on Table E.9.5,only Number 2,a boat cabin,is currently maintained for boating and hunt- ing. (b)Land Use Activity Hunting activity will increase and current patterns will change as a resul t of impoundments.The reservoi rs and access to them will facilitate floatplane landing and boat travel,and thus permit easier penetration by big game hun- ters into rarely visited areas.An increase in moose and caribou hunting will occur immediately adjacent to the pro- posed impoundments.Hunting for moose or caribou will increase only to the maximum allowed by the permit system. Game will be reduced by the effects of increased hunting and by the resource emigration caused from increased human popu- lation.Big game hunting guides will be affected by reduced hunt i ng act i vity and therefore reduced income.Gu i des may need to find a different occupation or move elsewhere. There is potential for increased fishing for resident spe- cies in tributaries feeding into the impoundments.A 1 imi- ted reservoir fishery may also develop.Salmon fishing in Portage Creek could increase due to the accessibility created for the Devil Canyon facility.Regulations can be requested to manage this fishery area. E-9-32 - - - - 3.2 -Construction Camps and Villages Fur resources will be eliminated in Zone 1 by the impound- ments.Ac.cess to the reservoirs will cause disruption of present trapping patterns within Zones 2 and 3. 3.1.3 -Mitigation The land management plans developed with the cooperation of jur- isdictional agencies will .include control of land use activities and will be implemented upon operation of the facilities.The land use plans will direct land use activities for the reduction of the impact on the game~fish~and furbearers resulting from increased land use activity. 3.2 -Construction Camps and Villages 3.2.1 -Proposed Facilities One construction camp (single worker housing)~village (family housing)~and associated facilities will be located at each dam- site.within the immediate project area;see Figure E.9.16 for their location.Construction of Watana Dam is proposed to begin in 1985~at least nine years later,construction at Devil Canyon will begi n.Pl ans are to bui 1d a const ruct i on camp and vill age at Watana for use until the dam construction phases down.The camp components will then be relocated to the Devil Canyon dam- site to the greatest degree practical.A permanent town wi.ll be constructed at Watana to provide housing and cmrununity facilities for workers who will operate the dams following construction.No permanent village is planned for the Devil Canyon site. The proposed camp and vi 11 age at Watana wi 11 be constructed northeast of the damsite between Deadman and Tsusena Creeks (Figure E.9.17).Approximately 1 mile (2 km)w"ill separate the construction camp from the village.Work on the village will begin about one year after construction of the camp has begun. Structures at the camp will be of factory-built ~modul ar design to facilitate their relocation to Devil Canyon. Facilities and services to be provided at the construction camp include housing modul es (dormitorl es)for about 3000 workers ~ camp offices~food services~warehousing~fire and security pro- tection~banking and postal services~hospital care,recreation, communications,and power generation.Facilities at the village will include family housing (to accommodate about 1000 people),a gymnasium,recreation center,shopping center (food supermarket, department and specialty stores),generating station,and struc- tu res for ot her support activities. Camp and village utilities will include a potable water supply system~sewage system,power supply and distribution system~ E-9-33 3.2 -Construction Camps and Villages communications,fuel storage,and a solid waste disposal system. The water supply is expected to serve an estimated peak popula- tion of 4030 (3070 in the camp and 960 in the village)including workers,famil ies,and visitors.The water source will be from Tsusena Creek and ground water wells.The treatment plant,also of modular design,will fulfill Environmental Protection Agency (EPA)requirements. Permanent facilities required for project operation at Watana incl ude a small community of approximately 130 staff members and their families.The town is planned at the site of the construc- tion village. The facilities at the Devil Canyon construction camp and village will be similar to those at Watana,though fewer workers will be accommodated.Up to 1900 peopl e wi 11 be housed duri ng the peak construct i on peri od at Devil Canyon.The camp wi 11 be situated south of Portage Creek and west of Devil Canyon on the south side of the Susitna River.The village will be temporary,unlike the one at Watana,and will be west of the camp (Figure E.9.18). Additional details on the construction camps and villages may be found in Exhibit A and in Chapter 5 of Exhibit E. 3.2.2 -Induced Land Use Changes (a)Watana (i)Land Use Development The construction camp and village will result in the dedication of 370 acres (150 ha)to community use during the construction phase.After construction has been completed and the camp and temporary village removed,the permanent town at Watana will occupy 90 acres (36 ha).Additional land will be required for connecting roads,an airstrip,and other facilities related to dam construction. Facilities and services constructed for the Watana ca rnp and v il 1age will be a vail ab1e for use by the residents of the permanent village.Once liviny fac il it i es are constructed duri ng the Watana con- struction phase,no further impacts are anticipated during Watana operation and Devil Canyon construction phases,or during the operation phase of both dams. All operat ions rnai ntenance personnel and thei r fam"il ies will 1 iv~onsite at the Watana permanent vill age. E-9-34 - ,.... - 3.2 -Construction Camps and Vi11~ges Water supp1 y and sewage treatment wi 11 be mai nta i ned onsite for use by the permanent vi 11 age.Landfi 11 s will be provided for the disposal of sol id waste. Police protection,fire protection equipment,and volunteer fire personnel will be available for onsite resi dents.Health ca re wi 11 be admi ni stered from a 20-bed hospital;hwoever,major illness and accident victims may need to be transported to other Mat-Su Borough fad1 ities.A school building will be pro- vided for the 300 school children anticipated.Edu- cation administration will be operated by the Mat-.Su Borough. The permanent vi11 age of Watana will be estab1 ished on 1 and presently se1 ected by the state only.Lands in proximity have been se1 ected by and conveyed to CIRI.CIRI will study any potential for development on project and adjacent 1 ands.All the Nati ve cor- porations have shown interest in offering profit o ri ented serv ices to the vi 11 age.at her 1 and deve 1- opments compatible with the project and with the cor- poration incentives are being investigated,such as various recreation plans.Land use development established by the Native corporation will be identi- fied individually as the need arises. - .- (i i )Land Use Activity Among the project's effects upon activity patterns are those impacts related to access.The chief effect of the Watana camp will be the activity asso- ciated with the ten-year construction period.The extent of impact on general patterns of acti vity in the Middle Susitna Basin will depend on the actual operating pol icies estab1 ished for the camp·duri ng the construction period.Dispersed recreational activity by construction workers could increase sig- nificantly in the absence of such policies.Con- versely,if there are extensive policies limiting dispersed recreation and other activities outside of camp,the effects 6n the basin will be minimized. (b)Devil Canyon - (i )Land Use Development Approximately 85 acres (34 ha)of presently undevel- oped land will be converted to community uses for the E-9-35 II 3.2 -Construction Camps and Villages construction period.Additional areas will be re- quired for connecting roads and related facilities. After construction is complete in 2002,all camp and village facilities will be removed. (ii)Land Use Activity The chi ef effects of the Devi 1 Ca nyon camp wi 11 be the associated construction activity during the con- struction period from 1994 to 2002.Controlled acti- vities outside of camp will determine the extent the construction workers will impact the activity pat- tern.Change in the activity pattern is expected to be less than that for Watana because of the smaller work force required for Devil Canyon. 3.2.3 -Mitigation Proposed development focuses recreational activities on core recreational facilities and indirectly diverts the users away from sensitive environmental areas outside the project area. Impacts from human use can be reduced if trails outside the pro- posed camps are establ ished and if specific areas are designed for leisure activity.Land use activities could be confined to project construction areas to discourage increased hunting,fish- ing and trapping in the project area.' Posting and enforcing construction camp rules will help make pro- ject personnel aware of adverse environmental impacts.Other mitigation measures to reduce increased 1 and use development of the camp and village and to increase construction worker produc- tivity may include restricting the use of private vehicles and providing transportation services.Transportation services could include air,bus,or van services,park and ride lots,travel schedules and/or travel allowances.Travel services may al so influence construction worker travel schedules which would alle- viate pressure on land use development and activity. Impacts from facilities associated with housing,such as sewage treatment lagoons and landfills,can be reduced if they are loca- ted away from existing or proposed developments. E-9-36 P'''-' .... - - 3.3 -Recreation 3.3 -Recreation 3.3.1 -Proposed Facilities Presently,there are no publ icly developed recreational facil i- ties within the vicinity of the project except for road rel ated facilities on the Denali and Parks Highways.Three privately- owned lodges exist at Stephan,High and Tsusena Lakes.Recrea- tional facilities to be provided in the project area as part of the overall hydroelectric development plan will reflect both the recreational potential which exists in the area and public input from the recreation surveys conducted as part of the recreation study. The recreation plan will be implemented in five phases as described below: (1)Watana Construct ion Phase (2)Watana Implementation Phase (3)Devil Canyon Construction Phase (4)Devil Canyon Implementation Phase (5)Post-construction Monitoring Phase The construction phases will consist of projects intended to mitigate the impacts of recreation opportunities lost due to construction,and to provide recreation opportunities to con- struction workers.Recreation facilities planned in each phase will be developed when the respective ~roject construction begins.' The implementation phases consist of recreation features intended to mitigate the impacts of recreation lost due to project opera- tion,to provide for the recreation use potential,to accommodate project-induced recreation demand,to allow public access and to protect environmental values.The implementation phase of recreation projects will be developed within three years of the operation date of the respective projects. The fifth phase consists of a recreation use monitoring program to begin when the first project recreation facilities are de- veloped.Monitoring is necessary to determine actual recreation use of the project features and to trigger adjustments in the recreation plan if required.Recreation projects planned in Phase Five will be implemented when necessary agreements are made between the agencies and when demand requires the facilities. CIRI Native corporations have shown interest in participating in recreation development to the extent of negotiating a recreation scheme for the benefit of the Native corporation shareholders. E-9-37 3.3 -Recreation Recreation projects in Phase One consist of an expansion of an existing campground on the Denali Highway,a shelter at the Tyone and Susitna River confluence,a boat launch and vehicle-trailer storage at the Denali Highway bridge over the Susitna River,a trailhead and parking at Summit,and a 25-mile (40-km)primitive trail along the Middle Fork of the Chulitna River to the head- waters of Tsusena Creek,with two overnight shelters.Other phase projects incl ude new campgrounds,shelters along proposed trails,temporary camp and townsite facilities,and a visitor center at Watana and Devil Canyon.(See Chapter 7 of Exhibit E). 3.3.2 -Induced Land Use Changes When the access road is open to the public,it is anticipated that,in addition to the attraction created by the new dam and reservoir,recreation enthusiasts will be attracted to the newly opened land.The wide variety of available recreation opportuni- ties is a major reason people move to and stay in Alaska.The percentage of Al aska's population that participates in outdoor recreation activities is among the highest in the nation. Alaskans have increasing amounts of leisure time and with flex- ible working schedules are able to devote longer periods of time to recreation.This may result in longer trips at greater dis- tances from the urban centers.Alaska is reportedly experiencing some over-crowding in existing recreation areas near Anchorage and Fai rbanks due to recent population growth.Recreational opportunities at weekend travel distances are increasingly popu- 1 a r. The primary land use impacts of initial construction activities extend beyond the relatively small physical areas being dis- turbed.An immense change in image will affect a large part of the river basin as the prevailing ambience of an untouched, inaccessible wilderness changes to one of intense activity. Impacts which physically change the natural resources have posi- tive and negative effects on the preference of and use probablity of existing recreation activity types and levels.Indirect im- pacts are those related to changes in user demand levels.These include the impacts of construction worker recreation and the influx of recreationists as a result of new road openings. (a)Land Use Development The recreation concept is based on minimal and primitive development having only 1 imited access within a managed wilderness area,as was determined preferable by the public. Facil ities should be developed and managed on an as-needed basis,starting with minimal services and expanding only when demand warrants it. E-9-38 ..... r- i 3.3 -Recreation The highest quality recreation opportunities are in the diverse landscapes adjacent to the reservoir sites,not at the reservoirs themselves.The complex recreation needs of the temporary construction camp workers and the permanent village were considered.The recreation plan will provide a variety of hi ghly developed .i ndoor and outdoor recreation faci 1 it i es,whi ch will sat i sfy demands without taxi ng the areas limited recreation capacity. (b)Land Use Activity A total of 50,000 visitor days per year are projected for post-project conditions in the year 2000.The recreation plan was developed to accommodate growth phased to Watana and Devil Canyon portions of the project.The proposed recreation facilities will provide for a challenging variety of activities and experiences within a development range from natural wilderness to semi-primitive recreat~on facili- ties.. Rail service may become available for public use at the com- pletion of the Devil Canyon damsite construction.Rail ser- vice will provide access with the project area within four hours from Anchorage,instead of the seven hours required to travel the road access.This will constitute a positive impact on recreational use with minimal effects caused by increased areas. r- I 3.3.3 -Mitigation The recreation plan proposed for the Susitna Hydroelectric Pro- ject will provide organi zed recreational development for project waters and adjacent lands.The recreation plan is designed to allow public access that protects the scenic,public recrea- tional,cultural and environmental values of the area.It esti- mates and provides for recreation user potential,accommodates project-induced recreation demand,and offsets recreational resources lost.The plan is intended to fit within the framework of the regional recreation plans and to provide additional oppor- tunities.The "impacts of construction and operation activities extend beyond the physical areas being disturbed and can be par- tially mitigated by careful management of the remaining lands for. public recreation and appreciation. Road and ORV access has been limited.Other access options such as boating,hiking and skiing have been provided in certain areas.Recreational development focuses activities on core recreational facilities and diverts the greatest number of users away from sensitive operations or environmental areas. E-9-39 3.4 -Access Details concerning recreation facilities are described in Exhibit E,Chapter 7,Recreational Resources. 3.4 -Access 3.4.1 -Proposed Facilities The access pl an is shown on Fi gure E.9.16.Transport of mater- ials and supplies to the Watana damsite will commence in part at the existing Alaska Railroad at Cantwell.A road will extend 2 miles (3.2 km)east from a proposed rail marshalling yard and storage facility,and will follow an existing route to the junc- tion of the George Parks and Denali Highways.Transport will proceed 21.3 miles (34 km)eastward on the Denali Highway. The road will be paved in the community of Cantwell from the 40- acre (16-ha)marshalling yard to 4 miles (6.5 km)east of the George Parks and Denali Highway intersection.This will elimi- nat e dus tan d fly i ng s ton e sin the res ide nt ia 1 dis t ric t.Sp eed restrictions should be imposed by the state along this segment for safety measures. A new access road will extend south from the Denal i Hi ghway at milepost 21.3.The road will be constructed for 41.6 mi les (67 km)across Brushkana and Deadman Creeks,extend south on the west side of Deadman Mountain across a tributary of Deadman Creek at milepost 28,and then parallel along Deadman Creek to the Watana dams ite.The road will c ross Deadman Creek via a bri dge to ensure adequate drainage and fish passage. The crown of the Denali Highway-Watana road will only be 2 to 3 feet (0.6 to 0.9 m)above the original ground level.Borrow ex- cavation will be confined to a 50-to 70-foot (15 to 27 meter) trench on each side of the roadway.The side slopes of the trench will be smooth and revegetated.Several pull-outs will be constructed along the access road to permit viewing of natural areas and some of the project facilities. Access to the Devil Canyon development will consist primarily of a 12.2-mile (20-km)extension of the existing Alaska Railroad at Gold Creek to a marshalling yard and storage facility adjacent to the Devil Canyon camp area.Materials and supplies will be dis- tributed using a system of site roads. The railroad will climb gently and steadily for 12.2 miles (20 km)from Gold Creek to the marshalling yard near the Devil Canyon camp,except for a 2-mil e (3-km)section where the route traverses steep terrain alongside the Susitna River.Several streams will be crossed requiring the construction of large culverts;however,no bridges will be needed. E-9-40 ,r'i> ,..,., _. - 3.4 -Access The rail road extension wi 11 be designed not to exceed a maximum grade of 2.5 percent nor a maximum curvature of 10 degrees. These parameters are consistent with those presently being used by the Alaska Railroad.Required right-of-way width will gene- rally be 200 feet (60 m)for the gentle-to-moderate side slopes of the road and railroad.The few areas of major sidehill cutt- ing and deep excavation will require additional width. The Devil Canyon and Watana damsite will be connected by a 37- mile (60-km)road to provide access to construction and operation and maintenance personnel stationed at Watana.From the marshal- ling yard at Devil Canyon the connecting road will be built to a high level suspension bridge approximately 1 mile (1.6 km)down- stream from the damsite.The bridge deck will extend over the Susitna River at an elevation of 1420 (430 (430 m),and the bridge length will be 1790 feet (540 m)with a main span of 1250 feet (380 m).The design of a high suspension bridge will reduce traffic congestion by maintaining travel speed at 40 mph (65 kmh) and reduced travel distance.Travel across a low bridge would require increased time due to reduced speed and travel across 8 miles (13 km)of switchback road. The Watana-Devil Canyon route extends northeast from the high suspension bridge,across Devil Creek and past Swimming Bear Lake,then southeast through a wide pass at an elevation of 3500 feet (1060 meters).The road continues east across Tsusena Creek to the Denal i Highway-Watana road.The moderate slopes will allow roadbed construction without deep cuts,balanced with the required fill amounts to minimize borrow excavation. Assessment of projected traffic volumes and loadings during con- struction resulted in the se1ection of the following design para- meters for the access roads. The 21.3 miles (33.5 km)of the Denali Highway will be upgraded to these design standards.Required realignment should be poss- ible within the existing easement. Grades and curvatures consistent with current highway design standards for a 55 mph (90 kmh)design speed were chosen for the efficient and economical movement of supplies.Since extensive grades and curvatures could result at some locations,the design speed will be reduced in certain areas to 40 mph (65 km)to allow - - Surfacing Width of Running Surface Shoulder Width Maximum Grade Maximum Curvature Unpaved 24 feet 5 feet 6 percent 5 degrees E-9-41 3.4 -Access steeper grades and shorter turn radii.Flex"ibility of design speed allows the road to follow the topographical contour more closely. 3.4.2 -Induced Land Use Changes The access route will be built for construction and operation of the dam facilities.Many of the effects will be related to long- term consequences after construction is complete.The road will provide access to Native conveyed land in the section north of each damsite and,when constructed,over the dam at Watana and across the Susitna Ri ver via suspension bridge at Devil Canyon. Increased access into this existing remote area is the major land use impact of the project. As discussed in the previous subsection,the existing land use is predominantly individual recreational use and commercial recrea- ti on developnent.Access will introduce an infl ux of peopl e and will instigate activity within the basin that will affect popula- tion concentrations,isolated residences,peripheral commercial establishments and transportation systems,resource utilization, the level of recreation activity,and the overall character of the a rea.These effects coul d i nfl uence changes in 1 and value and will initiate comprehensive land use management. Access extending from the Denali Highway will cause effects in the Cantwell area.Land use changes at Cantwell are further di s- cussed in Subsection 3.4.2 (a).Road access will cause both the disruption of present land use and the inducement of future land use.Provision of access into the Susitna Basin is a more signi- ficant impact than is the physical road.The provisions of easy, inexpensive road access into the area will cause alterations to the Susitna Basin's character.The remote wilderness,presently accessible only by air,ORV,foot or water will become an area of hydroel ectric development intensely used by project rel ated per- sonnel,people interested in observing the hydroelectric facili- ties and the variety of Al askan envi ronments offered in the Middle Susitna Basin,and by residents as far away as Anchorage and Fairbanks for recreational purposes. Rail access to Devil Canyon originating at Gold Creek will allow the transportation of materials,equipment,and labor through Gold Creek.There will be a significant impact on Gold Creek and on Hurricane and Talkeetna,the last railroad junctures with highway access to the north and south of Gold Creek,respective- ly.The use of the railroad to ship materials to Devil Canyon Dam will cause less of an impact to other communities along the Pa rks Hi ghway. E-9-42 3.4 -Access -Goods or people could travel by rail to the Devil Canyon site. This will reduce the extent of impact on community land use along the Parks Hi ghway.Access by road from the Denal i Hi ghway to Watana would increase off-road vehicle use in areas where itis now low.Thi s introduct ion coul d aggravate alterations to the terra i n. The proposed access would likely cause less of an effect to resi- dents along the Parks Highway since direct access from the Parks Highway is precluded.The road from the Denali Highway would permit car travel by the public into the interior of the basin. The Fairbanks population is considerably smaller than that of Anchorage;therefore,potential human use of the basin via a new road would be reduced with access extending from the Denali High- way due to the increased distance from Anchorage.In addition, virtually no development exists along the Denali route,so dis- ruptions to existing land use would be minimal. The Denali access road wi 11 provi de access to CIRI and vi 11 age corporation lands for possible resource development.This is considered a positive step by the corporations.Recreation,min- ing,and timber harvesting have been ~uggested as possible acti- vities. {~)land Use Development r Improved access,:increased use,and markets for commercial ,services will macke the :lanel in th.e project vicinity more attractive to prospective commercial and residential buyers. Commercial and residential dey,elopment may increase,escala- ting the land value. A total of approximately 374 project-induced households are expected to settl e in the Mat-Su Burough between 1983 and 1990,the height of construction at Watana.This in-migra- tion is not expected to cause dislocations in the borough's -housi ng market.The maj ori ty of p roject-re 1ated housi og demand will "be concentrated on the northern part of the borough.Low vacancy rates,are expected in Trapper Creek and Talkeetna"since additional housi ng will!be bui It on ly to satisJy demand.,It is;expected that housing for pnoject- related households at uantwell will be available due to entrepreneurial activity.Mc:rs:t of tttR I{rivately-owned 1and in Cantwell is owned by Atitirra~j Inc..,IJBv·efo.Jlment for hous i ng will be subject to Ahtnars~apl+raiisa1l of the economic feasi- bility of the developmen1;l.Under a moderate impact sce- !"""nario,it is projected',that housing will b-e:available for less than half of the-115 project-related household demand bet.ween 1984 and 19t;HJ~ E-9-43 3.4 -Access The access roads between the Denal i Hi ghway,Watana,and Devil Canyon,and the railhead at Cantwell,will not direct- ly create significant impacts on land use development.Jobs w"ill be created for their construction and operation.The i ndi rect i nfl uence the access road will have on the'local communities will be more significant as labor and materials pass within their vicinity (TES et al.1981). The termination of the rail system at Cantwell,the closest community to the damsites via road,will create a signifi- cant change to Cantwell.The size of population influx into Cantwell will be heavily influenced by the development of housing in the community by private individuals and by miti- gating measures that can be implemented.Support sector employment will develop as personnel arrive that are direct- lyemployed toward the construction or operation of the pro- posed fac i1 it i es.As the communi ty popul at i on increases, individual developers will need to increase maintenance to continue current levels of road service,and additional roads may need to be built to serve additional subdivisions. Increased pol ice protection,emergency health care,educa- tional capabilities,and business activity will require developnent and construction proportional to the increased population. The popul ation may increase by over 200 percent of the 1 evel expected without the project at Cantwell and over 100 per- cent at Trapper Creek.Talkeetna will experience a 10-50 percent increase in population.Construction and land use development will increase proportionally.Palmer,Wasilla and Houston will experience less than 2.5 percent increase in population,housing and schools,but a 2.5-10 percent in- crease will be experienced in the development of service sector employment,business activity and transportation facilities. The extent of -1 and use development wi 11 be determi ned by regional communities.Cantwell,Palmer,Wasilla and Houston are generally in favor of the changes di scussed above. These communities want more economic development,parti- cularly jobs.Residents of Trapper Creek and Talkeetna have i nd i cated that rapi d,uncontroll ed change is not desi red. Residents who would like to have controlled economic devel- opment want to consider potential changes to their community as a res ult of the proj ect before committing to a growth plan.Some communities are already governed by land use stipulations.For example,the Indian River Subdivision is restricted to recreational use by the Talkeetna Mountain Special Use District regulations. £-9-44 3.4 -Access The railroad wi 11 traverse through Gol d Creek to a rail head at Devil Canyon.This rai 1 spur will significantly impact population and the development of support sector employment, business activity,housing and transportation in Gold Creek and,to a lesser extent,Talkeetna. The extent of land use development in surrounding communi- ties will depend on the transportation program employed; this could include combinations of airplane,bus,personal vehicle with associated park and ride lots,travel schedules,and/or travel allowances. (b)Land Use Activity The popul at ion increase of Mat-Su Borough as a result of project construction will be cumulatively (on-and offsite ,-residents)4700 in 1990.When the access road is opened to the public,recreation enthusiasts will enter the project area for the wide variety of available outdoor recreational opportunities at weekend travel distances.Post-construc- tion recreation visitor days per year are projected to be 50,000 in the year 2000.The volume of this recreation increase will change the existing land use activity patterns significantly. Hunting will increase to the maximum allowed by the permit system for moose,caribou,and bear along the access corri- dor.The increased number of hunters will disrupt existing hunters and force them to adjust to reduced resources or to relocate into other remote areas.Locations accessible to hunters wi 11 be greater if ORV use is substanti al. Fishing will increase with potential effects on reduced resour,ces and on peopl e who currently fi sh in the area. Improved access to the mi ni ng aggr'egat ions along Portage Creek and Gold Creek may improve the economic feasibil ity of mineral exploration and mining. The Watana-Devil Canyon access road will disrupt current use patterns at High Lake Lodge.Disruption might also occur to fly-in fishing and hunting around the lakes near Devil Canyon.Some trapping territories recently established around the Hi gh Lake area woul d al so be altered.In addi- tion to increased hunting and fishing,this area will also receive increased recreational use for hiking,backpacking, sightseeing,and other activities. E-9-45 3.4 -Access Topographical conditions occurring along the Watana-Devil Canyon access road may induce ORV use,degrading the road1 ess experi ence of current users.The pr imary users affected will include fishermen,trappers,miners,and travelers using the existing sled road in the project area. Disturbed users will also include lodge and cabin visitors. All of the access route segments wi 11 affect the di spersed recreation currently enjoyed by hunters,winter enthusiasts, and back country hikers. 3.4.3 -Mitigation To reduce impacts from the proposed access route,several manag- ement techni ques can be desi gned.The access route shou1 d not cross unstable soils or wetlands to the greatest degree practi- cal.Disturbed sites could be restored to a stable condition. Staging areas and parking lots used during construction could be planned and designed to be used for future scenic and recreation pullouts for the public.A fire protection and prevention plan cou1 d be formu1 ated to decrease the fire hazard associ ated with increased access. Land use activity will be confined to within project construction areas until the facilities are built.This will reduce the im- pact of land use activity until the implementation of the land use management plans takes place. If the use of off-road vehicles (ORV)originating from the access route becomes a di sturbance,measures wi 11 need to be taken to inhibit this activity.Such measures would include a buffer strip designated for non-motorized use adjacent to the access route.natural conditions employed as subtle but absolute deter- rents to ORV use,designated and planned ORV trails in locations that wi 11 neither conf1 ict with other 1and use nor damage the env,ironment,and,if necessary,ORV restriction between the pro- posed damsites.Spur roads to private holdings and mining claims will be designed,located,and constructed similarly. Recreational use extending from the access route will be directed to sites designed to support such use.The proposed recreational facilities will accommodate recreational demand and replace opportunities lost. 3.5 -Transmission 3.5.1 -Proposed Facilities Maps of the transmission route are included in Exhibit G.Tile central transmission route is illustrated in Figure E.9.16.The E-9-46 - 3.5 -Transmission land use aggregations and existing structures for the project impoundment area are illustrated in Figures E.9.8 and E.9.9, respectively. Figures E.9.4 and E.9.10 illustrate land tenure and land use development of the Anchorage-Willow transmission line.Figures E.9.5,E.9.6,E.9.11,and E.9.12 illustrate land tenure and land development for the Healy-Fairbanks transmission line.The corridor width studied was 3 to 6 miles (5 to 10 km),included both sides of the river,so therefore,was 14 miles (23 km)wide in some central corridor segments.The transmission route analy- sis involved mapping within the corridor,the land use develop- ment and activity,and land tenure. The process of environmentally screening the original 22 corri- dors involved comparison of study area options based on the following eight constraints categories:length,topography! soils,land use,aesthetics,cultural resources,vegetation, fish,and wildlife.Following review of the environmental and engineering analyses,one transmission corridor was selected for each of the three study areas.Constraints within that corridor were then examined and a 0.5-mile (0.8-km)route within the cor- ridor was sel ected. From Watana to Devil Canyon,two si ngl e-circuit 1i nes will be constructed in a 300-foot (90-m)wide right-of-way specified within the proposed 0.5-mile (0.8-km)wide corridor.Four single-circuit 345-kV lines will extend from Devil Canyon to the intertie near Gold Creek.A 510-foot (155-m)wide right-of-way will be selected for the proposed Devil Canyon-Gold Creek corri- dor.Watana to Gold Creek was considered the central study area. The location of the Watana-Gold Creek transmission line is gene- rally from the Watana dam across and adjacent to the north side of the Watana-Devil Canyon access road.It will cross the Gold Creek -Devi 1 Canyon rail road twi ceo Speci fically,the central transmission lines extend from the Watana Substation,located in the Southwest Quarter of Section 28,Townshi p 32 North,Range 5 East of Seward Meridian.The right-of-way will extend northwest for 2.2 miles (3.7 km),west by northwest for 7.4 miles (12 km), northwest for 6.5 miles (10.9 km),and then southwest for 12.5 miles (20 km).At this location,two lines from the Devil Canyon Substation located 0.7 mil es (1.1 km)east in the Northwest Quarter of Section 32,Township 32 North,Range 1 East of Seward Meridian,parallel the Watana-Gold Creek lines.Four lines extend southwest from this junction for 2.2 miles (3.7km)then west by northwest for 5.3 miles (9 km).The Devil Canyon Switch- ing Station is located in the Northwest Quarter of Section 1, Township 32 North,Range 2 West of the Seward Meridian. £-9-47 3.5 -Transmission Three lines will extend from Gold Creek to Anchorage.The right- of-way will be 400 feet (120 m)wide and will include the Alaska Power Authority's intertie to Willow.Between Anchorage and Willow the southern transmission study area parallels Chugach Electric Associations existing transmission line east of Knik Arm. From Gold Creek two lines will extend north including the Alaska Power Authority's intertie to Healy (Commonwealth Associates, Inc.1982).The right-of-way will be 300 feet (90 m)including the intertie's right-of-way.The corridor of the northern study area to Fairbanks parallels Golden Valley Electric Association's (GVEA)transmission line for many miles. Most of the towers will be X-shaped structures approximately 100 feet (30 m)tall.Two cable guys will extend from the crossbar of each tangent structure to a centerl ine anchor on each side of the structure. Each line will have 105 feet (31 m)between the centerlines and 95 feet (29 m)of right-of-way on either side.The vegetation in an 80-foot (24-m)strip below each transmission line will not extend above 2 feet (0.6 m).The 25-foot (7.6-m)strip between transmission lines will have vegetation growth 10 feet (3 m) tall,cut in an irregular fashion to break up the visual linearity of the corridor.Traverse strips 30 feet wide (9 m)of low vegetation,will extend between the transmission structures of each line.' Tree clearing along the outside edges of the right-of-way will be feathered.At approximately 40 feet (12 m)from tile centerl ine the tree height will be 10 feet (3 m).Tree heigllt will increase as the distance from the centerline increases at a 30°angle from ground level.Trees along the outside edge of the right-of-way will be acceptable to approximately 45 (13.6 m)feet tall on level terrain.Trees growing outside of the right-of-way that could encroach on minimum conductor clearance when falling will be flagged and felled by hand tools or hand held power tools. Double circuit construction may be required in areas such as the Municipality of Anchorage to allow a narrower right-of-way. Double circuit structures will be similar in design to the single circuit structures,only 50 feet (15 m)taller. Tile transmission routes have been located to avoid recreation areas,residential areas,and special interest land.For example,the Anchorage-Willow transmission line avoided the Nancy Lake State Recreation Area,and the Susitna Fl ats State Game Refuge is only marginally traversed.The Healy-Fairbanks route E-9-48 - ..... 3.5 -Transmission deviates from Golden Valley Electric Association's (GVEA) transmission route and parallels the Alaska Railroad for 7 miles (11 km)in an effort to avoid multiple crosslngs of the Parks Highway.Private land holdings and communities such as Willow were major considerations in route'se1ection. The proximity of the transmi ssion 1i ne to the access road wi 11 provide ground access to the line in all weather conditions.A trail will extend from the access road to each transmission structure.'A minimum standard acceSs trail will extend the entire length of the transmission route suitable only to a11- terrain vehicle use.These trails will not be maintained during winter but cleared only as necessary,unlike the Watana-Devi1 Canyon access road. 3.5.2 -Induced Land Use Changes Constl"uction activities cause both short-and long-term impacts on resources.The creation of new access will add significantly to the potential for disturbance caused by the transmission line. Efforts were made to parallel existing utility corridors and to utilize existing access wherever appropriate. Maintenance activities during the operational phase of the lines can a1 so cause adverse impacts as a result of right-of-way clearing.Impacts will vary depending upon the timing and method of right-of-way maintenance and can be minimized through careful prescription of maintenance techniques. (a)Land Use Development The Anchorage-Wi 11 ow route crosses or parall e1 s numerous trails,including the Iditarod Trail,seismic survey lines, tractor and pioneering ORV trail s,and several recreational trails near Willow (ADNR 1980),as illustrated in Figure E.9.10. Residential use occurs in Willow,Red Shirt Lake,and on many of the small lakes east of the Anchorage-Willow route. Scattered cabins in the vicinity of Willow are close to the Alaska Railroad and Parks Highway.Red Shirt Lake has approximately 25 cabins along its shores.Seven other lakes have several cabins along their shores,and a few cabins are widely scattered e1 sewhere.The proposed route wi 11 not directly affect these existing structures,although the lines and towers may be visible in areas west of Long Lake, Red Shirt Lake,and smaller lakes where topography is not sufficient to screen them from view • E-9-49 3.5 -Transmission The Anchorage-Willow 1i ne route traverses 5.3 mil es (8.9 km) across the Point MacKenzie Agricultural Sale located north by northwest of Poi nt MacKenzi e (see Fi gure E.9.10).Land within a transmission right-of-way can still be cultivated, but the towers would displace small areas of existing and potential farmland and disrupt normal patterns of cultivation and future agricultural development. The corridor and portions of the western boundary of the Anchorage-Willow route incl ude the northeast corner of the Susitna Flats State Game Refuge.All land use development in a game refuge must be determined to be compatible with the purposes for W1 ich the refuge was created. On the east side of Knik Arm inlet the line route passes through the Fort Richardson Military Reservation parallel to the existing Chugach Electric Association,Inc.'s Point MacKenzie-University Substation line. The Healy-Fairbanks line route parallels Golden Valley Electric Association's (GVEA)existing line for 12 miles (20 km),then parall el s the Al aska Railroad for 7 mil es (ll km).The line continues north on the east side of the Parks Highway and railroad to avoid multiple crossings of the highway.The GVEA existing transmission line extends from an existing substation at Healy to an existing substa- tion at Ester.The Healy-Fairbanks line route parallels the GVEA 1 ine intermittently for 15 miles (25 km)before enter- ing the Ester substation. There are several moderate concentrations of land use devel- opments along or adj acent to the proposed route between Healy and Fairb.;lnks.Significant among these is the devel- opment at Healy,Nenana,and Ester.In Healy and Ester, existing land use and the proposed transmission route will be juxtaposed.Other residenti al areas passed by the pro- posed line include communities adjacent to the Parks Highway or the Alaska Railroad.These include lignite,Ferry,and Brown.Few cabins exist in the vicinity of the Healy- Fairbanks transmission route. Numerous trails,light-duty roads,and a sled road are in the vicinity of the Healy-Fairbanks transmission route as we 11 as the Parks Hi ghway and the Al aska Ra i1 road (ADNR 1982).Many landing strips or airports are in the vicinity as well as the U.S.Air Force Clear M.E.W.S.Military Reserve.These include one at Healy,two at Lignite,one at Rex,and an airport at Nenana and Fairbanks.

Fi gure E.9.11~some agricultural 1 and north of Healy through \'h1ich the proposed wi 11 trav-erse approximately 3 mil es (b)Land Use Activity The rw-oposed route between Willow and Knik Arm northeast of Poi nt MacKenzi e will traverse an area that recei ves di s- persed but increasing use.Boating occurs along the Susitna and Little Susitna Rivers,Willow Creek,and on numerous small lakes.Potential conflicts between the rw-oposed lines and private lands and boating use may occur wherever the lines and towers will be visible.Floatplane flight patterns may be affected where the 1i nes pa ss near 1akes used for landing and taking off. Trails that receive substantial ORV use are located near Willow,Red Shirt Lake,and Knik Arm.The proposed route will not affect the physical use of trails,although visual conflicts may occur where the lines pass the trails. Extensive mining occurs along the Healy-Fairbanks transmis- sion route concentrated at Ester and to its west. - ..... i 3.~3 -Mitigation Efforts were made to select transmission line routes that would minimize negative impact.Proper a1 ignment of the transmission line right-of-way wit~in the route could reduce the line's obtru- siveness.Techniques employed to reduce the impact of the trans- mission line include following the Chugach and GVEA existing transmission corridors and initiating their structure design, spaci ng,and conductor materi a1 •Other techni ques used to mi n- imize disturbance include right-of-way clearing designed to be unobtrusive by breaking up the linearity and feathering the tree height,locating the right-of-way away from private and special "interest land,and by maintaining the access roads only when necessary in winter. The impact of the transmission line routes from Gold Creek to Healy and Willow will be minimal because the route will be within the same corridor as the Alaska Power Authority's Healy-Willow intertie transmission line.The construction of the Power Aut hor i ty I s Wi 11 ow-Heal y i ntert ie will be complete upon commence- ment of the rw-oposed Susitna transmission construction.The im- pact of the proposed transmission lines will be reduced because they win parallel and be adjacent to the approved intertie ri ght-of-way. E-9-51 3.6 -Changes in Land Use Without the Project Agencies,Native corporations,and the private sector have been heavily involved in the selection and transfer of land ownership under the Alaska Statehood Act and the Alaska Native Claims Settlement Act.Land selection is complete.Without the development of the Susitna Hydro- electric Project the urgency to determine the ownership of the land in the project area will be lessened.The conveyance of land will con- tinue in the project area;however,other areas of proposed development will have higher priorities for the state and Native corporations. The project area has not been exploited in the past because of limited economic feasibility.Discussions with land owners/managers and consi- deration of present market conditions indicate that,without the pro- ject,little change is likely to occur in existing land use patterns. Even if the state of Alaska or the Cook Inlet Region,Inc.and village corporations sell remote parcels surrounding the accessible lakes,it is unl ikely that there will be any significant change unless access into the area is improved.Native land owners have expressed inten- tions to exploit the mineral potential of lands south of the project area;however,no speci fi c pl ans have been identifi ed due to 1 imited access. E-9-52 "",. - - - 4 -DESCRIPTION OF CHANGES IN LAND STATUS AND MANAGEMENT 4.1 -Land Status Changes Resulting from the Project The land required for the dams,the Devil Canyon reservoir,and a por- tion of the Watana reservoir has been selected by the Natives.The proposed locations for the Devil Canyon camp and village,as shown in Figure E.9.16,have been selected by CIRI as illustrated in Figure E.9.3,and could be transferred to CIRI and associated Native village groups.The proposed locations for the Watana camp and village are on state selected land.The transmission line routes are primarily on state land.Sections of the northern transmission corridor crosses land that has been designated for village selection within Doyon,Ltd. boundaries.Sections of the southern corridor are owned by CIRI. Transfer of title for state sel ectedl and will not be affected by the project.A means of land acquisition will have to be established for the access roadan.d transmission line corridor,either through purchase or by obtaining a right-of-way,before the initiation of construction. A decision by the state to proceed with the Susitna project woul d en- tail transfer of ownership of substantial land areas to the state.The process for such transfer has not yet been established but could entail purchase and/or an exchange of other state selected lands with Native corporations. The exchange of fee simple land between the state and a regional Native corporation will involve each agency's determination of parcels suit- able for exchange.Market value and appraisals are made for each par- cel and are compared for exchange.A comprehensive status check is performed to determi ne if the 1 and is subject to regul ati ons.A 1 and use report and land classification may be required and public hearings will be held. ADNR and the Native corporations have expressed interest in identifying the project related land use requirements and alternatives in a manner that will prevent irreversible impacts to land management.In order to prevent this issue from being a potential delay in project progress, recommendation has been made to convene in a multiagency,multidisci- plinaryeffort.Carefully determined decisions could result in a multi pu rpose proj ect whi ch coul d facil itate and enhance other uses of the surrounding la.nd.Future management problems for landowners and land managers could be minimized. E-9-53 4.3 -land Management Changes Resulting from the Project 4.2 -Land Status Changes Without the Susitna Hydroelectric Project With the exception of a few scattered parcels,most lands in the pro- ject area are presently under federal title,withdrawn from acquisition or development pending conveyance of Native and state selections authori zed by ANCSA and the Statehood Act,respectively.Si gni ficant changes in the land selection are not anticipated in the project area whether the project proceeds or not.Land exchanges are oeing consi- dered between Ahtna,Inc.and CIRI.CIRI and the village corporations have not completely determined which method CIRI will reconvey land to the village corporations. 4.3 -Land Management Changes Resulting from the Project Based on available information and agency interviews,it has been determined that little comprehensive management exists at present. Agencies establishing management plans have been influenced by the feasibility analysis of the Susitna Hydroelectric Project.Not all the management plans described below were instigated by the Susitna Hydro- electric Project;however,as feasibility of the Susitna Project became probable,comprehensive plans have been adjusted accordingly. The Bureau of Land Management (BLM)has no proposal s for management planning in the study area,other than the existing Denali/Tiekel P1ann ing Block s• A draft Denal i Sceni c Hi ghway Feas i bil ity Study and recommendations regarding the proposal will be released in March 1983.The Susitna Hydroelectric Project access road was considered in the analysis of the scenic highway feasibility report.The project proposal,construction, and 1and use are not expected to impact the scenic highway proposal. Public hearings for the Scenic Highway Study will be held in March 1983.The Alaska Land Use Council will make its recommendation follow- ing the receipt of public comments and after reviewing the compatibil- ity of the Scenic Highway proposal and other plans.The compatibility of the Susitna Hydroelectric Project and the Denali Scenic Highway will be determined at that time. The ADNR is preparing a land use report that describes and categorizes potential land use in the south-central region of Alaska which will be completed by approximately May 1983.A land use plan will be completed by the ADNR in 1986.The ADNR recommends close coordination between the development of the Susitna Hydroelectric Project and the Susitna Area Comprehensive Land Use Plan. The ADF&G has developed species-specific objectives for the region,but it has no land management authority.Other agencies have preliminarily addressed 1and management concerns.The generati on of hydroe 1ect ri c E-9-54 "... I""" [ - ~ , r ".... .... 4.3 -Land Management Changes Resulting from the Project power will become the predominant land use in the area,and the pres- ence of the project will be an importance factor when agencies eventu- ally develop comprehensive land management plans. The Mat-Su Borough has prepared a planning background report.The Mat-Su Borough wi11 complete a draft comprehensive land use plan in January 1983. The Fairbanks North Star Borough is preparing a borough-wide,compre- hensive plan.The first section will describe the potential land use and will give a general comprehensive plan;it will be available in July 1983.By 1985 specific land use plans,policies,and regulations for subdivisions and zoning will be available. Increased access will allow land use activity to become more intense, especially by individual users.Therefore,the provision of access will result in a need for increased management and use controls in the Middle Susitna Basin.After titles or legal rights-of-way are obtained for construction and operation of facilities,public access could result in increased use levels of private lands;fishing and general use of the project area are probable.These activities may require increased fi sh and wi I dl i fe management and/or may resul tin surface- disturbing activities. Specific controls may be required to protect resource value within the project boundaries.Land use control woul d derive from management plans designed by the land owners/managers.These plans should be coordinated with adjacent land owners/managers to be compatible with adjacent land management.Controls could include establishing acquisi- tion limits for hunting and fishing,permitting a limited public entry, ORV management,and other I and use management. If the Al aska Power Authority I eases project-requi red I and from the Native corporations,the Native land owners will dictate the land use pol icy by vi rtue of a permit system subj ect to federal or state law. The Native land owners will implement the land use control authorized to them by the U.S.Congress via ANCSA in 1971.Such control could include restrictions to trespass,use of ORVs,rockhounding,and access to recreational trails that cross their land.Permits to hunt,fish and use Native land will be the tools to regulate the restrictions. Finalizing specific management plans and mitigation measures for trans- mission line right-of-way,access,recreational use,and residential accommodations will proceed during Phase II of the Susitna Hydroelec- tric Project.The Alaska Power Authority will work closely with the aforementioned development of land use plans • E-9-55 4.4 -Land Management Changes Without the Project Land management in the project area is tenuous because of the emphasis on the determination of land ownersh"ip and the uncertain outcomes of the Al aska National Interest Lands Conservation Act and the Susitna Hydroelectric Project (USOTA 1977).The BLM Denali Planning Block will dictate the policy for lands within its boundaries and may influence management decisions on BLM land in the vicinity. Ahtna,Inc.and its village corporations will establish land value and the economics of recreational,mining and residential land use upon the BLM's conveyance of land.CIRI and its village corporations will do so after the procedure for CIRI's reconveyance of land to the villages has been determined and implemented. The ADNR and t~at-Su Borough have recently increased thei r effort to establish management plans in the project area as a result of project feasibility studies.Land management plans completed for the project area will not change should the hydroelectric project not be construc- ted.The implementation of those plans will proceed at a slower rate. The establ ishment or completion of new plans may be postponed.The efforts of personnel of the Sus itna Area Pl anni ng Team may be redi- rected to areas of greater activity such as south and west Mat-Su Borough where development will establish along the highways and rail- road as a result of growth in Anchorage and south-central Alaska. E-9-56 r - - 5 -AGENCY CONSULTATION AND MITIGATION PLANS Agency consultation is described specifically in Section 6,Authorities Contacted.Comments received from the Alaska Department of Fish and Game and the U.S.Fish and WildlHe Service included comments on miti- gation measures.The following general response is toward those comments,and is more specifically addressed in the Chapter 9 text. Specific agency comments and responses are itemized in Chapter 11. Measures to mitigate the land use impact will be determined along with juristictional agencies such as the Alaska Department of Natural Resources,Matanuska-Susitna Borough,Fairbanks North,Start Borough, The Municipality of Anchoragee,and the regional Native Corporations when these agencies have determined the preferred techniques to imple- ment increased land use management. Chapter 9 has described the limited historical land use of the project impoundment area and the progress of land management pl ans.Land management has only become a concern in Alaska in the last twenty years.Agencies have recently been selecting land to acquire and will develop management plans upon the completion of land acquisition.The agencies have anticipated the approval of the Susitna Hydroelectric Proj ect and have increased emphasis on 1and management -j n the project area,.Once the scope of the project and the potenti al impacts to the resources are identified,the agencies can coordinate management plans to mi nimi ze the project impact,manage the 1and use effectively,and facilitate and enhance other use in adjacent areas. Specific mitigation measures addressed in Chapter 9 include designing housing facilities that minimize environmental impact;directing personnel away from environmentally sensitive areas via proposed recreational facilities;providing recreational opportunities that off- set recreational resources lost with a recreation plan compatible with the regional recreational framework;inhibiting ORV activity if it becomes a disturbance;aligning the transmission line according to the terrain and the existing and potential land use;and designing and managing the transmission line right-of-way to reduce visual,biologi- cal,and human impact. Restrictive access has historically limited public use of the project area.Unlimited access into the area could bring about excessive public use and associated socioeconomic and biological distress.The recreation plan will accommodate recreational demand and replace recreational opportunities lost as it simultaneously directs activity to more resilient ecosystems. Specific mitigation measures to reduce the impact of the transmission line are presented in Subsections 3.5.1 and 3.5.3.Right-of-way man- agement techniques include feathering adjacent tree height;1 inear and transverse undulation of the cut tree line;and clearing the transmis- sion line access road,only as required for maintenance access to the transmission structures.
