RECREATIONAL RESOURCES 1 -INTRODUCTION 1.1 -Purpose The purpose of the Susitna Hydroelectric Project Recreation Plan is to provide organized recreational development for project waters and adja- cent lands and to focus public access in the project area.This plan is intended to be compatible with the existing environment and consistent with the planned construction and proper operation of the hydroelectric project.The plan has been designed to meet four primary obj ect i ves: To focus public access on project lands and waters and to protect the scenic,public recreational,cultural,and other environmental values of the project area; -To est imate and provi de for the recreat i on user potent i al for the project area; -To accommodate project-induced recreation demand;and -To offset recreat i ona 1 resources lost by construction of the proposed proj ect. 1.2 -Relationships to Other Reports This Recreation Plan is based,in part,upon the project description presented in Exhibit A,project operations described in Exhibit B,and the proposed construction schedule described in Exhibit C.While the recreation plan constitutes a mitigation,it also becomes part of the project features,and as such has i rnpacts in itself.Thi s pl an has therefore been coordi nated wi th other sections of Exhi bit E;pri mari ly Chapter 3,Fish,Wildlife,and Botanical Resources;Chapter 4,Historic and Archaeological Resources;Chapter 5,Socioeconomic Impacts;and Chapter 9,Land Use,so that they may assess its impacts. 1.3 -Study Approach and Methodology (a)Approach The planning approach is guided by the following factors; -Construction phasing and access; -Operational characteristics of the project; -Management objectives of the interested agencies and Native corporations; -Recreation use patterns and demand; E-7-1 -Intrinsic landscape resource opportunities and constraints, -Facilities design standards; -Financial obligations and responsibilities of the Alaska Power Authority;and -Federal Energy Regulatory Commission regulations. The approach is divided into six steps,as follows: -Analyze and describe operational characteristics,construction phasing,management objectives,and facilities design standards 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 1evel s;and -Describe mechanisms for plan implementation,construction and maintenance. Section 1.4 describes the proposed Sustina Hydroelectric Project. Section 2 describes the existing recreation within the statewide and regional settings.Included are descriptions of facilities, activities,and the relationship of the project to existing recre- ation use patterns.Section 3 describes the impacts on recreation of the Watana and Devi 1 Canyon project features,access routes, and the transmission lines,and projected demand for recreation with and without the Susitna Project. Section 4 describes the factors influencing the recreation use plan.These factors include APA,agency,and Native corporation management objectives,design standards,and Alaska Power Authori- ty financial obligations and responsibilities. Section 5 is the Recreation Use Plan including intrinsic recrea- tion potential,recreation opportunity evaluation,development levels and proposed sites.This plan constitutes mitigations for impacts identified in Section 3.Section 6 describes the Recrea- tion Use Plan implementation,phasing,monitoring and future addi- tions.Section 7 describes the costs associated with construction operations and maintenance of proposed facilities. E-1-2 - - /8I'I!IPl'1, I~' -, Every effort has been made to utilize the results of past studies and agency plans both of the Susitna ProJect itself and of a more general nature.Particular emphasis has been given to the Susitna Hydroelectric Project Subtask 7.08 Report,Recreation Planning, May 1982,prepared for Acres American Incorporated by Terrestrial Environmental Specialists,Inc.and the University of Alaska, Fairbanks.Use was made both of that published report and the field data and background files utilized in its preparation. Additional results of a survey conducted as part of that effort have also been utilized in the formulation of this Recreation Pl an. (b)Methodology Figure E.?l illustrates the study methodology employed in devel- opment of the Recreation Plan for theSusitna Hydroelectric Project.Step 1 determined study objectives and developed a de- tailed work plan.This activity included review of all relevant agency documents and interviews with key agency personnel identi- fied by the Alaska Power Authority.Objectives of each agency were determined as they relate to this Recreation Plan.They are reported in Section 4 of this document.When combined with FERC. Order 184,they constitute 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 meth- odo logy for est i mat i ng future recreat i on demand was used as a basis for a project-related recreation demand methodology.In addition,four other approaches were utilized as a general check of resul ts. Step 3 consisted of an on-site inventory of existing recreation potential.This activity involved study of existing relevant pro- ject documents and previous studies,and extensive on-site inves- tigations.Step 4 evaluated recreation opportunity based on in- formation from Step 2 and defined the qualitative and quantitative aspects of site recreation potentials. Step 5 is a further refi nement of the opportunity eva 1uat ion,and constitutes alternative and recommended recreation plans for the project. Step 6 developed an implementation plan,including plan phasing, demand monitoring,and estimated costs. A detailed discussion of specific methodolgy employed is found in the individual report sections. E-7-3 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 lines,a railroad,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-Fa ;rbanks Intert ie,a separate project pl anned for construction beginning late 1982 and scheduled for operation in Septem- ber 1984.The Intertie is not considered in this Recreation Plan. (a)Construction (i)Watana Dam and Reservoir The Watana schedul e ant i ci pates issue of the FERC 1i cense by December 31,1984 (see Exhibit C)and is predicated on having four units on line by the end of 1993 and an addi- t ional two units by July 1994 in order to meet forecasted load demand.Construction of an approximately 41-mile access road commencing at mile 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 3,480 \'wrkers and a construction village ultimately housing 350 families (1,120 population)will be developed.These and the various contractor yards and appurtenant construction facilities ~"ill be served by a temporary 138-kV transmis- sion line following the Denali Highway and the Watana access route to the construction site.Construction labor for the 885-foot-hi gh,4,lOa-foot crest 1engthembankment dam and the 1020-MW powerhouse will peak in 1990 with about 3,500 workers. Construction of the two 33.6-mile-long 345-kV transmission lines will begin in 1989 and extend through 1992.They wi 11 be constructed primari ly in the wi nter months.Im- poundment of the 38,000-acre,54-mile-long reservoir with a gross storage capacity of 9,470,000 acre feet will begin in June-1991 and be completed in late 1993.As development nears completion,a permanent town near the construction camps,intended to house a permanent work force of 125, plus dependents,wi 11 be constructed and the ori gi na 1 camps will be relocated to the Devil Canyon site. E-7-4 - - - (i i)Devil Canyon Dam and Reservoir Devil Canyon construction is planned to begin as Watana approaches completion.Between early 1992 and mid-1994,an access road wi 11 be developed between Watana and Devi 1 Canyon,i ncludi ng construction of a hi gh-l evel bri dge across Devi 1 Canyon.(See Fi gure E.7.2.) A rai 1road wi 11 be constructed from Gold Creek to Devil Canyon.The Alaska Power Authority will defer decision on the public 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 construction materials will be brought to Devil Canyon on a new 14-mile railroad from Gold Creek.A single-status camp for 1,780 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-kW Watana transmission 1 ines will be tapped for construction power and the temporary construction line from Cantwell to Watana will be dismantled.Construction work- force for the 646-foot-hi gh,1650-foot crest-l ength thi n- arch concrete dam and the 600 MW powerhouse '",ill peak at about 1,800 workers in 1999 and extend to 2002.Two addi- tional 8.B-mile-long,345-kV transmission lines will be built to connect with the Intertie.An additional parallel 345-kV will be added to the Intertie itself.Impoundment of the 7,BOO-acre,32-mile-long reservoir with a gross storage capacity of 1,090,000 acre feet will occur over a two-month period in 2001.The project will then be on line in 2002.The constructi on camp and vill age wi 11 be re- moved,and both Watana and Devil Canyon will be operated by the same personnel resident at the Watana townsite.It is assumed that the road connecti ng Watana and Devi 1 Canyon will be opened to the publ ic and the railroad,no longer needed for continuous project use,will potentially be available for public use. (b)Operational Characteristics of the Project (i)Watana Dam and Reservoir The Watana Dam and Hydroelectri c Power Pl an is intended to provide base load power supply supplementing existing and planned thermal and hydroelectric sources for the Railbelt beginning in 1993.Present plans also call for operation of Watana as essentially a base loaded plant from 1993 to 2002 at which time it will be used as a daily peaking plant for load following during the high demand winter months. Watana Reservoir will have a typical width of one mile, widening at tributary streams to a maximum of five miles at maximum water level at Watana Creek.Crest elevation of the dam will be 2210 feet,and water surface elevation E-7-5 during maximum probable flood conditions will be 2202 feet. Normal maximum operating elevations will be 2185 feet in September with a lm-/of 2065 feet in April or May.During breakup and through the most imporant recreation months of June,July,August and September water levels will be increasing,reaching a peak in September.Live storage area wi 11 be 3,740,000 acre feet and drawdown fl ats may range from a few hundred feet in canyon areas to several mil es in fl atter areas such as Watana Creek.(See Fi gures E.7.8,E.7.9,and E.1.10. 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 below Devil Canyon;Sunshine, approximately 49 mil es further downstream,and Sus i-tna, another 53 miles downstream.At Gold Creek,flows approach 6,000 cubic feet per second (cfs)in October,the start of the water year.This rapidly decreases in November, December,January,February and March (low:1,123 cfs)as the river freezes for the winter.At breakup,flows are over 13,000 cfs in May and peak at about 27,700 cfs in June.Flows gradually decrease in July (24,000 cfs), August (22,000 cfs),and September (13,000 cfs).The effect of the Watanaproject as currently planned will be to both moderate these wide fluctuations and also to redistribute flows,raising them in the winter,to provide energy in these high demand months.Flows ~"i11 fluctuate only from about 7,700 cfs (April)to 13,400 cfs (August) contrasted with 1,100 cfs (March)to 27,700 cfs (Ju ne) under natural conditions.Flows will increase over natural conditions in seven months:October through April.They will decrease in the remaining months.In the important recreation months of June through September,flows will be decreased from current flows.At Sunshine and Susitna,the same general patterns pertain,although the effects are proportionately much less as additional water sources join the river.The entire upper basin of the Susitna contri butes 1 ess than 20 percent of the total Susitna discharge into the Cook Inlet. (i i )Devi 1 Canyon Dam and Reservo;r The Devil Canyon Dam and Power Plan is intended to provide base load power supply.It will also operate as a re-reg- ulating dam for peaking flows from Watana,modulating downstream flows. Devil Canyon Reservoir will have a surface area of 7,800 acres,with a 1ength of 32 10;1es,contai ned ina narrow E-7-6 ,~ ...... -' - - """I canyon generally one-quarter to one-half mile wide.It will extend nearly to the toe of Watana Dam at maximum ele- vation.Crest elevation of the dam will be 1472 feet,and water surface elevation during maximum probable flood con- ditions will be 1466 feet.Normal maximum operating eleva- tion will be 1455 feet most of the year with a low of 1405 feet in October (normal dradown:50 feet).(See Figure E.7.4.)Unlike Watana,which will be operated with a September-October hi gh and an Apri l-May low,Devil Canyon \t/ill remain at its normal elevation from October through July.It will be draw down in August and September,be at a minimum elevation of about 1405 feet itl September,and refill in October.Table E.7.1 also compares pre-and post-project flows showing combined Watana and Devil Canyon a perat i onsat the three downstream locations.Flows tend to decrease slighlty in October,May,June,July and August compared with the Watana-only operation,and increase slightly in the remaining months. 1.5 -Implications of Project Design and Operation on Recreation Planning The physical character of the reservoirs themselves and the operational characteristics of the projects have important implications for es- tablishment of the recreation plan concept: The fast-flowing river and the river canyon experience which attracts a very sma 11 number of kay akers and other ri ver runners wi 11 be changed into a lake experience between Vee Canyon and Devil Canyon. -Both lakes will be cold and silty.Watana in particular is large enough that wi nd and chop condit ions caul d constitute potent i a1 .hazards for small boat recreationists. -The 1arge drawdowns,parti cul arly at Watana,wi 11 create 1 arge mud- flats which will be unattractive,difficult to cross,and sources of blowing 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 problem than drawdown.In either instance,development of boating facilities will be extremely diffi cult. -Large bank slumps,landslides and scales will be unattractive and potentially dangerous. Other lakes and streams in the project area already constitute recre- ati on resources whi ch are far superi or to the proposed reservoirs. Road access will greatly increase their use potential,particularly to sports fi shermen •. -Hunters,and to a 1esser extent sports fi shermen,will conti nue to fly into the area. E-7-7 -The image of the area will continue to be one of a very distant loca- tion remote from population centers as the road position causes the dams to be over 5 hours away from both Fairbanks and Anchorage.The IIdead-end ll nature of the access road will discourage casual drive- through tourism. Whi le there is some opportunity for cross-country sk i development, climate and di stance wi 11 1i mit the area to predomi nant 1y summer recreati on. -Opportunities are primarily for primitive-level recreation facilities except at the dam and powerhouse sites themselves where some visitor interpretation and related facilities are appropriate. E-7-8 - - - "'"" 2 -DESCRIPTION OF EXISTING AND PLANNED RECREATION 2.1 -Statewide Setting (a)Background Recreation environments and the people who recreate in Alaska are quite different in many ways from the lower 48 states.Therefore, in order to understand the recreation issues of the Susitn-a Hydro- electric Project,it is first necessary to know the issues facing the state with regard to recreation and to know the attitudes of Alaska residents and tourists.. The open spaces of A1 aska contai n some of the most pri sti ne and spectacu1 ar scenery and the most sensit i ve wil d 1ands in the nation.Having the smallest and youngest population with 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 recreation opportunities.However, as rapid land status changes take place,a reduction of the avail- able public recreation land and opportunities is imminent. The 1971 Alaska Native Claims Settlement Act will transfer 44 nrr1- lion acres of public resource lands to private ownership within the next few years.The conveyance is still in progress;however, many of the selected lands include established recreation areas. In addition,the State Legislature has directed the Alaska Depart- ment of Natural Resources (DNR)make available to the public state lands for settlement or agriculture.Although the law has been amended to establish an assessment method for determining the need of private lands by region,this process continues to remove over 20,000 acres a year from public ownership. The federal government has set as i de more than 100 mi 11 i on acres through the Alaska National Interest Lands Conservation Act (ANILCA),adding 43.6 million acres to the National Parks System and 53.7 million acres to the National Wildlife Refuge System. Two million acres were placed in BLM conservation and recreation areas.Fifty-six million acres of the National Park Refuges and Nat i ona 1 Forest 1and were gi ven wil derness protect i on.These lands represent many beautiful and sensitive areas of Alaska and greatly expand the area of lands in protected status available for outdoor recreation.However for the most part,these areas are remote and not easily accessible by either out-of-state visitors or residents. Alaska State Parks,a division of the Department of Natural Re- sources,was formed in 1971,and currently controls 3 million acres of land and water.DNRls policies and programs reflect the recent land status changes.In 1979 DNR began the Public Interest Land Identification Project to evaluate surface use values of state lands.This ongoing project identifies the best areas for E-7-9 wildlife 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 of Alaska's 367.7 million acres are now classified as public recreation.This in- ventory is presented in Table E.7.2. (b)Regional Setting The Sus itna hydroelectric study areal i es within the Southcentra 1 Re-gion of Alaska.Recreation planning for this development must fit within the framework of existing and future regional recrea- tion.Therefore,it is important to understand the regional rec- reation patterns and trends as well as the Di visi on of Tasks pl ans for the future. Thi s-region extends from the hydrographi c di vide of the Al aska 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 large diversity of landscapes and resources here offer a wide variety of outdoor recreational opportunities making it an attrac- tive recreation environment.See Figure E.7.4 for Existing and Proposed Regional Recreation Areas. More than half of Alaska's population lives in Southcentral Alaska.Anchorage,the largest city,had a 1980 civilian popula- tion of 174,400.The region's economy is based on:support serv- ices,commercial fishing,mining,forestry,petroleum,tourism, and other private business.Economic trends are primarily toward natural resource-rel ated development.Touri sm,although rated second in importance for the state's economy,is the foremost i n- dustry supporting the i~at-Su Borough economy. Southcentral Alaska contains the most highly developed transporta- tion system in the state.It is interconnected by paved highways a nd gravel secondary roads provi ding good access to many areas. An extensi ve airport system rangi ng from the i nternati onal 1evel to gravel strips and water bodies permit plane access into much of the remaining areas.The Alaska Railroad and ferry systems also serve large portions of the region.All of these transportation systems combine with the population concentrations to make the Southcentral region's recreational opportunities the most easily accessible and heavily used in Alaska.See Table E.7.3 for inven- tory of statewide recreation facility distribution by regions. (c)Existing Facilities The Alaska State Parks System includes 82 park units;53 of these are in the Southcentral Region of the state.Table E.7.3 E-7 -10 -- - - descri bes the di stri but i on of facil it i es throughout the state by regi on and i 11 ustrates thi s development concentrat i on.Outdoor recreat ion developments in the Southcentra 1 Regi on are pri mari 1y located to serve the two major population centers of Fairbanks and Anchorage and the Rai1be1t area connecting them. The region1s largest and most popular attraction,for both out-of~ state tourists and state residents is the Denali National ~ark and Preserve.It is located about 220 mi 1es north of Anchorage and 125 miles south of Fairbanks on the Parks Highway.It offers vis- itors views of Mt.McKi n1ey and other major peaks as well as abun- dant wildlife.The park attracted over 250,000 recreation visi- tors in 1981.Facilities and services include several lodges, visitor centers,campgrounds as well as trials,gas and bus service.The adjacent Denali State Park,also accessed by the Parks Highway,abuts the Susitna study area.It contains over 324,000 acres and offers 37 miles of scenic driving,a major road- side campground,trials,picnic grounds and canoeing and fishing areas.A total of 519,000 visitors utilized this park in 1981. Seventy mil es from Anchorage,Nancy Lake State Park has 23,000 acres and 130 1 akes and ponds.It is heavily used by Anchorage residents for water-related recreation as well as hiking and camp- i ng (100 units).Chugach State Park,10 mil es to the east of Anchorage,provides extensive hiking and cross-country skiing opportuniti es.The park covers 494,000 acres and offers major campgrounds (91 units),hiking,hunting,boating and fishing. Lake Louise,northeast of Anchorage and reached off of the Glenn Highway,is a popular fishing,boating and hunting area.The lake is a desti nation poi nt for boaters and provides access to the upper Susitna and Tyone rivers. North of the Susitna project site,the Bureau of Land Management maintains the 4.4-million-acre Denali Planning Block.This area encompasses much of the Dena1 i Hi ghway and i nc1 udes several arch- aeological sites of nationa.1 significance.The Bureau maintains severa 1 small campgrounds and pi cni c areas a.10ng the hi ghway,boat launches,canoe trail,and two campgrounds at Tangle Lakes.There are campgrounds at Brushkana Creek and C1 earwater Creek. The Susitna Flats State Game Refuge to the north of Anchorage and the Chugach National Forest to the east also absorb a large por- tion of recreation demand for the southern portions of the South- central Region.A great many recreationists from Anchorage go to the world-famous Kenai Peninsula parks,over 100 miles south of the city.This area offers the widest range of Alaska recreation. Features include superior fishing,big game hunting,scenic driv- ing and skiing as well as lake and saltwater recreation. Numerous private facilities in the region provide additional formal and informal recreation opportunities.These include re- mote lodges,cabi ns,restaurants,airstri ps and f1yi ng servi ces, guide services,white-water rafting and other boat trips. E-7-11 --,,~~----- The town of Talkeetna serves as the operations center for Mt. r~cKinley mountaineering expeditions.People from all over the world come to this old mining town to fly out to the mountain base and other recreation points.In addition to mountain climbing, other recreation activities which serve as Talkeetna1s economic base include:hunting,fishing,guiding,tours,and sightseeing. A listing of existing recreation opportunitles in the region is included in Appendix £o7.A. (d)Existing Regional Recreation Use Outdoor recreat ion is a way of 1 ife in Al aska.Accordi ng to the major source document used by recreation planners in Alaska to assess demand,the wide variety of recreation opportunities avail- able is a major reason that people move to and stay in Alaska. Only self-reliance is considered more important,and being close to the wilderness was the third most important reason Al askans gave in a recent survey.Selected Findin s from the Alaska Public Survey,USFS,NPS,and University of Washington,1981 • The percentage of Alaska's population that participates in outdoor recreation activities is among the highest in the nation.Accord- ing to that recent statewide recreation survey,59 percent of the respondents in the southcentral area reported that they enjoy driving for pleasure.Over half of the respondents walk or run for pl easure and a full 42 percent go freshwater fi shi ng.Tabl e E.7.4 lists and ranks the percentage of participation in various inland activities within the region.Southcentral residents rank their favorite recreation as fishing,tent camping,hunting, trail-related activities,baseball and bicycling in that order. (Alaska Outdoor Recreation Plan,1981).In contrast,tourists to the area have indicated driving for pleasure as their favorite activity followed by camping,hiking and sports fishing.(Alaska Division of Tourism,1977). Table £07.5 outlines the total visitor count summary for Alaska State Parks 1978 to 1980.Figures for the Mat-Su and Copper Basin Park districts describe the Susitna River Basin as it was analyzed for t hose data. Over 389,000 visitors came to Alaska for pleasure trips in 1977. Thi s represents a 13 to 15 percent annual growth rate si nee 1964. Recreation growth rates are difficult to predict with confidence, as they rely on many variables,including world economic condi- tions.However,the State Division of Tourism projects that in the year 1985 up to 1,000,000 tourists will visit Alaska.The main reasons tourists give for being interested in Al aska were studied in a poll by GMA Research Corporation in 1980 for the Division of Tourism (Alaska Outdoor Recreation Plan,1981). E-7-l2 - 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 hunt i ng Percent 40 25 10 10 15 (e) In terms of numbers of vi sitors,the most important out-of-state tourist areas in Alaska are the Gul.f of Alaska,Anchorage,and the Denali National Park which is within 80 miles of the future Susit- na dam sites. Future Recreation Trends Southcentra 1 Alaska is reportedly experi enci ng overcrowdi ng in some existing recreation areas near Anchorage and Fairbanks due to recent population growth.Assuming that the present recreation participation rate remains constant,the region will experience a significant annual increase in demand.However,recreation par- ticipation in the United States and Alaska may increase faster than the popul at i on growth if current trends continue.Alaskans have increasing amounts of leisure time and with flexible working schedules are able to devote longer periods of time to recreation. Thi s may result in longer tri ps at greater di stances from the urban centers.In recreation areas which have received up to·50 percent of their users from the cities of Anchorage and Fairbanks, intensity of use increased three-fold in the late 1970s and the recreation season has lengthed by several weeks.(Source:Alaska State Park System Southcentral Region Plan). According to the Southcentral Regional Plan,sports fishing 1 i cense sales increased 40 percent from 1975 to 1980.Increased use of accessible fishing streams has caused overcrowding in popu- 1ar areas throughout the regi on and in part i cul ar those streams nearest the urban centers.Interest in boating is also rising. Sales of boating equipment increased significantly in the late 1970s,and the Knik Kanoers and Kayakers Cl ub of Anchorage has experienced rapid growth in recent years.There is also evidence of a rapid increase of interest in winter recreation as surveys of winter recreation equipment sales over the last seven years show. (Clark &Johnson,1979 public survey). A statewide 1981 public survey (Selected Findings from the Alaska Publ ic Survey)polled Southcentral residents to determine their recreation needs and priorities.Twenty-five percent of the resi- dents responded that they would most like to do more fishing,12 percent more tent camping,7 percent said hunting,and 8 percent said motorboating.Bad weather,lack of free time,closed sea- sons,overcrowding and high transportation costs are reportedly E-7-l3 the most common reasons that prevent res i dents from i ncreas i ng their activities.When asked what priorities the State Parks Department should have for future development,residents advised the Department to acquire more campgrounds,hiking trails,develop recreation trails,backpacking campsites and boat trails.How- ever,Al askans woul d prefer only to mai ntai n exi sti ng wi 1derness areas,not expand these further. Also in the 1981 survey,sixty-one percent of the Southcentral residents are reported to like more recreation opportunities at weekend travel di stances,'and 62 percent waul d 1 ike more community recreation development.When asked how many hours they would travel for weekend recreation,17 percent said over 4 hours,11 percent said over?hours,and a full 20 percent were .willing to go over 6 hours from home for a weeked trip.This is generally believed to be supported by existing travel patterns. The features that people most des ired in out-of-town recreat ion areas i ncl ude: - - Feature -Fishing areas -Water access Developed camping and picnic sites -Undisturbed natural areas -Hunting areas -ORV trails %of Population in Favor of Features 95 91 91 88 87 7 Source:Alaska Outdoor Recreation Plan~1981 (f)Future Facilities In 1982 the State Parks Division published an aggressive plan to expand recreation opportunities within the Southcentral Region. This plan reflects the leading role the State Parks Department has in providing outdoor regional recreation.The plan has chosen to respond to all of the existing unsatisfied demands and projected needs of the region.(See Figure E.7.4 and Table Eo7.7 for future Regional Facilities.) State Parks development priorities include several recreation sites that will affect the Susitna Hydroelectric Project Recrea- tion Plan.They are listed in Figure E.7.6 and include the following: Denal i State Park,to the west of the Susitna project,has been studied as the site of the Tokositna Resort which would offer first-class hotel facilities,cultural attractions,commercial developments,indoor recreation,alpine skiiing and other winter sports as well as the traditional outdoor recreation already offered in the park.While this project is no longer under active consideration due to uncertain feasibility,preliminary studies E-7-14 - - - i 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 ever be developed,it would accommodate sig- nificant proportions of projected recreation demand in the state. In other areas of the Denali State Park development is going for additional picnic areas,campgrounds,boating facilities and trails.Along the eastern portions of the park future trail heads have been desi gnatedi n conjunction with railroad stops.These trai 1s woul d connect into the western-most portion of the Susi tna study area. The existing Lake Louise Recreational Area to the southeast of the Susitna study area is a popular boating and fishing area.Current expansion plans will add 300 acres to the existing 50 and will include several campgrounds,boating facilities and canoe portage trails.This development also a high priority as the lake is experi enci ng heavy use.The adjoi ni ng Susitna Lake and Tyone River have been identified as possible boating recreation areas for possible development at a later time.Boaters are able to float from the Susitna bridge on the Denali Highway down the Susitna and up to Lake Loui see Other opportunit i es for boati ng include Tangle Lakes,Big Lake,and Kepler Lakes. The State Parks Division has also identified the Talkeetna River as a possi b 1eState Recreat ion Ri ver.These 1ands have been sel ected by the CIRI Vi 11 age Corporati ons for conveyance.The proposed recreati on area woul d extend from the ri ver mouth at Talkeetna up to the confl uence of Talkeetna and Prairie Creek.It is possible that new legislative designation will not need to take pl ace but that means to protect the ri ver wi 11 be sought under existing legislation.Boaters currently fly in to Stephan Lake located at the head of Prairi e Creek,whi ch is in the Susitna study area;then they float the Talkeenta River down and into the Susitna Ri ver at the town of Talkeetna.This Cl ass IV waterway attracts 4-5 parties per year,of 3-6 people each,and takes 2-3 days.(Personal communi cati on,Mary Kay Hessi on,Knik Kanoe and Kayak Club). Several other proposed new parks and park expansions given a high priority by DNR are listed in Appendix E7B,Future Regional Recreation Opportunities. 2.2 -Susitna River Basin - (a)Background During the past decade the Upper Susitna River Basin has been studied and evaluated by numerous state and federal agencies.It has not met criteria required for inclusion in any of the follow- ing recreation and conservation programs: E-7-l5 -"""'--__,~...-~--A~,",·~-.-'-------~, -National Park -Preserve System -Wild and Scenic River System~(including recreation) -National or Historic Landmark Status -Wilderness Preservation System -National Trail System -National Forest System -State Park System As no federal withdrawals were made ~both the State and Native Corporations have selected lands for transfer to state or Native ownershi p. (b)Existing Facilities and Activities The upper Sus itna Ri ver has yet to be developed as a si gnfi cant recreation resource and the present level of use is limited as a result of several major restrictions.The study area is immense~ and isolated.Road access is limited to the edges.For the pur- poses this Recreation Plan~the study area which was evaluated for recreation sites is generally defined by the Parks Highway on the west ~the Denali Hi ghway on the north ~the Sus itna Ri ver on the east~and about 20 miles south of the Susitna River.The Parks Hi ghway is separated from the area by a steep ridge system. Denali Highway is about a five-hour drive from Anchorage and three-hours from Fairbanks~which puts the area beyond the limits of a one-day auto trip for most residents in the region.Interior road access consists of a few all-terrain vehicular (ATV)trails and rought roads into a few sett 1ed areas.Plane tr ips into the river take approximately 2 hours from Anchorage and Fa irbanks. Small planes are the most common form of access into the area although a few ATV and hiking trails do exist.Boat access is possible on a limited basis.Various types of watercraft float and motor along parts of the ri ver above Vee Canyon and its trib- utaries. No public recreation facilities presently exist within the study area except for the road-related facilities on the Denali~Parks and Richardson highways. Along the Denali Highway~BLM maintains several small roadside 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 E-7-16 - - ... - - ""'" - - the Sus itna Hydroe 1ectri c Project Recreati on Pl an are the 33-site campground at Brushkana Creek and the boat 1aunch at the highway bridge over the Susitna River. A complete listing of the existing public and commercial developments within and adjacent to the study area is listed in Table E.7.6. Exist i ng pri vate recreation developments withi n the study area include clusters of small seasonal cabins and commer- ci al lodges.There are approximately 110 structures withi n the study area.Chapter 9,Land Use,includes a comprehen- sive table of all existing 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, Chuni 1 na Creek,Stephan Lake,Cl arence Lake and Bi g Lake. Most are used in associ at i on with hunting,fi shi ng and other recreat i on act i vi ties.Some of these 1ocat ions ar e accessible by ATV trails,but most are located near dirt airstrips and large water bodies for access by/plane. The greatest concentrations of physical developments are located around Stephan Lake and Portage Creek.Portage Creek is a mining area with some summer cabins;it contains 19 cabins and other structures.Stephan Lake is a commer- cial lodge site.Other developments at Chunilna and Gold creeks are primarily mining establ ishments.The 10 small cabins along the Susitna River banks are currently used by boaters,hunters,etc.passi ng through.The three commer- cial 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 mai n structures and seven addit i ona lout lyi ng cabi ns,and receives the greatest number of visitors annually.Serving a predominantly European clientele,it offers a variety of outdoor recreation activities in a wilderness setting including hunting,fishing and float trips down the Talkeetna and upper Sus itna ri vers andPr airi e Creek. High Lake Lodge is the second largest complex lodge with 11 structures and is located northeast of the proposed Devi 1 Canyon damsite at Hi gh Lake.Hi stori cally,thi s lodge has provided guests with services that are simil ar to Stephan Lake Lodge for hunting and fishing activities in a wild- erness area.The lodge is currently bei ng uti 1 i zed by Susitna project personnel doi ng summer fi el d research. E-7-17 Tsusena Lake Lodge is located north of the proposed Watana dams ite 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 during the summer and fall months with little or no use during the ~'1inter months. The existing trail systems were bui 1t for access by pros- pectors,hunters,trappers and fishermen.(See Table E.7.8 and Figures E.7.5,E.7.6,and E.7.7 for a complete listing of trail locations,condition and use).At figures present these trai 1s and rough roads are used by horses,tracked vehicles,ro11i90ns,dogsleds and hikers.They connect a few scatte~ed recreation developments and mining settlements and the camps used for researching the area1s hydroelectric potential.Trail s emanate from scattered structures out to airstri ps,1akes and adjacent fi shi ng streams. BLM is currently developing regulations for the management of the public trails located on lands which the Native cor- porat ions have selected.A tota 1 of six easements ha ve been identified within the study area.(See Exh-ibit E, Chapter 9).These include an access trail 50 feet wide from the Chulitna wayside on the Alaska Railroad to public lands immediately east nf Portage Creek;a state site ease- ment and trail easements on Stephan Lake;and an access trail running east from Gold Creek. The following trail information was reported in the Area Notes prepared by DNR Division of Research and Development as part of the Upper Susitna Basin Recreation Atlas. The Snodgrass Lake Trail begins at the Denali Highway near the Susitna bridge and proceeds south to the lake.The tra il reportedly recei ves use dur i ng summer,autumn and winter months.Recreation activities include moose,brown bear,caribou hunting;fishing,camping,off-road vehicular use,picnicking,wildlife observation,berry picking,snow machining,overnight camping,and cross-country skiing. The Portage Creek Trail follows a sled road from Chu1 itna to Portage Creek.Hikers access the trail via the A1 aska Railraod at Chulitna.The trail is used in the autumn, summer,and winter months.The trail is popular with hunters of moose,car i bou,brown bear and black bear,as well as hikers,campers,fi shermen,photographers and berry pickers.Portage Creek also receives a light level of fishing effort.Most of this trail transverses Cook Inlet Region,Inc.(CIRI)-se1ec~ed lands. The Butte Lake Area is used duri ng summer,wi nter and autumn months.There is a CAT trail connecting the Denali E-7-18 - - - - - ..- ,- (i i) Highway and Butte Lake.This trail is used by skiers, snowmachiners,hikers,fishermen,berry pickers,and campers.There is some fi shi ng effort for grayl i ng and 1 ake 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. A trail runs from Denali downstream along the west bank of the Susitna River.At the confluence of the Susitna and Maclaren rivers the trail continues east up to the Maclaren River and then turns south.This trail connects to other trails leading to Lake Louise or Crosswind Lake and ulti- mately to the Glenn Highway.This trail is used by off- road vehicle drivers,snowmachiners,hunters of car'ibou, moose and brown bear,fishermen and possibly dog mushers. Bird watching is also popular along the Denali Highway between the Susitna Lodge and Swampbuggy Lake. Activities Aside from these isolated lodges,cabins and trails which constitute a commitment to a particular site,the predomi- nant recreat i on pattern is di spersed and non-s i te specifi c. Activities include the consumptive recreations such as hunting,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. Sports and Trophy Hunting is a traditional activity in the Upper Susitna Basin.The three commercial lodges in the area serve as bases for hunting groups that fly in for gui ded trophy hunts.The lodges typi ca 11y handl e 15-20 guests at a time and jointly total 120 guests per season. (Source:Environmental Studi es Subtask 7.07,Land Use Analysis).In addition,many hunters fly into the larger 1 akes and util ize the small lakeside cabins for both guided and unguided hunting trips.Hunters also use ATV vehicles and horses to gai n access to more remote areas.The most popular big game include Dall sheep,moose,caribou,black bears and brown bears.Alaska Department o~Fish and Game data indicate that the recreation study area had about 600 hunter-days for moose,caribou and sheep in 1981. Fishing is an activity which frequently occurs here in association with other activities such as hunting,boating, and camping.Local residents have long enjoyed high qual- ity fishing in area lakes,streams and rivers.They com- monly fly into the 1arger 1akes for a 11-day or weekend trips.Lake fishing is concentrated at Fog,Cl arence, Watana,Tusena,Deadman,Big and High Lakes,while stream fishing occurs mostly along the creeks accessible by land such as Portage Creek. E-7-19 -----~,--_._........_--------------- Sa 1mon mi grate the Sus itna up to Portage Creek just below Devil Canyon.Both guided and individual fishing trips are popular here.Considerable salmon fishing also occurs in Stephan lake and Pra ir ie Creek as boaters travel upstream on the Talkeetna Ri ver to Prairie Creek.Other popul ar salmon fishing spots include lower Portage and Chunilna creeks and Indian River.There is litle stream fishing elsewhere in the area.lack of road access is an important 1 imit i ng factor on fi shi ng in the area.There are many popular salmon fishing areas further downstream on the Susitna River and its tributaries. Food Gathering.Very little site-specific data are cur- rently available on food-gathering patterns within the study area.Some berry-picking areas are known near Chulitna to the east of the study area and several more are along the Denali Highway. Rock Hounding.Much of the mineral exploration which currently takes place within the study area is commercial in nature and as such is discuseed in Exhibit E,Chapter 5, Soci oeconomi c Impacts.Thi s wi 11 change now that the BLM 1 ands have been opened for expl orat i on and as 1ands are conveyed to Native Corporations. Boating.There is summer boating on many of the lar.ger lakes by visitors who are flown in.Riverboat and guide servi ces are offered from Talkeetna and from the vari ous lodges downstream of Devil Canyon.The river is considered navi gabl e by a vari ety of craft i ncl udi ng rafts,canoes, a irboats and ri verboats up to Portage Creek. The Susitna River itself is used for fishing and access to hunt i ng.Boating activity takes pl ace south of the study area near boat launches at Willow Creek,Kashwitna Landing, Sunshine bridge and Talkeetna.The upper Susitna above the proposed reservoirs is calm and provides good canoeing. Some boaters reportedly float the river from the boat 1 aunch on the Denal i Hi ghway down to the Tyone River then motor up to the 1 ake at its source.A small number of boaters continue down the Susitna to the gaging station above Vee Canyon where they pullout and portage to Watana Lake for fishing.The upper Talkeetna River in the south- ern portion of the study area,rated Class IV,offers some of the finest rafting and white-water kayaking in Alaska. Talkeetna River is not easily accessible by land,and air access is usually into 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.Alternate put-in E-7-20 - - - - - - - -. - ~- .~ .~ (c) points may be available by landing on sandbars in the Ta lkeetna Ri ver.The take-out poi nt is usually at the town of Talkeetna.This is a two-three day trip (personal communication,Mary Kay Kession,Knik Kanover and Kayak Club). Riverboat traffic is heavy on the Talkeetna up to the Larsen Creek confl uence.Ri verboat and ai rboat traffi cis also common to the confluence of Prairie Creek,but is not as intense as it is downstream.Fi shermen boat to the mouth of Larsen Creek and lt/alk a mile into Larsen Lake. Fishing is light on larsen Creek and Lake as well as at the mouth of Disappointment Creek. Two to three parties of two to three individuals venture down through the rapids of Devil Canyon each year.This wi 1d stretch of ri ver,cl assified Cl ass VI,whi ch roars through 11 miles of a narrow vertical canyon is described by veteran kayakers as the Mt.r~cKinley of kayaking •.The first successful runni ng occurred in 1978.Less than 40 kayakers from various parts of the world have attempted it since that time,·and at least five people have died tryi ng. Cross-country skiing takes places in the area,particularly near Denali Highway.Occasional tour packages have been offered by the local private lodges.Snowshoeing has also become a purely recreational sport here.A limited amount of trapping takes place on the south side of the Susitna Ri ver near Stephan and Fog 1akes 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 reportedly centered around Trapper Creek and Talkeetna to the south. Future Activities and Facilities Shoul d the Sus itna hydroe 1ectri c project not be developed,the major obstacles which have limited past recreation activities will continue make it difficult in the future,although Native Corporations may seek to develop their lands for recreational uses.Unless vehicular access is developed into the study area, no major shift in the existing .low-level recreation patterns is anticipated.The parties which will control future recreation activities and development in the study area include:Alaska state government,U.S.Bureau of Land Management,several Nat i ve corporations and various other private landholders • The policies of these groups concerning the land parcels they con- trol along with overall increased pressures for recreation oppor- tunities from Alaska residents will largely determine the future £-7-21 patterns.The exact nature of specific activities and develop- ments is difficult to predict as land ownership decisions are in abeyance .and not likely to be resolved for several years.In addition,several major projects within the region could signifi- cantly affect future recreation.These are listed in Section 3.5 of this report.Additional public land sales could also change the recreation emphasis in the area. - - The Native corporations have selected much of the land aQjacent to the river and along Portage Creek and Talkeetna River.The _ corporations have not identified any specific plans for develop- ment if the hydroelectric development does not occur. Development possibilities which have been discussed include: mineral extraction and recreation home land development.Access appears to be the prime determenent 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 ~~ithin their planning areas (which i ncl ude the Susitna study area).They project a demand for 29,000 acres 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 home sites with Alaskans from other areas. The lands selected Qy Native corporations near the Susitna River meet all of the aesthetic criteria for prime lots according to the study (Land Use Issues and Preliminary Resource Inventory,Volume I,May 1982).However,without improved road access considering the landis building limitations,the property was given a rating of moderate capability and sales are unlikely to be significant. Nat i ve corporati ons have a1so expressed a preference for 1and leasing rather than sale. BLM policies for the Denali Planning Block reflect the goals of increasing recreation use of the area.Their plans include road improvements to the Denali Highway and additional roadside im- provements such as new campgrounds,picnic areas,and pull-outs. BLM is projecting an increase of the average annual daily traffic along the highway to 130 in the year 2000.Existing ADTis 50 cars.Formal designation of BLM land for additional ATV use appears to be no longer under consider.ation.BLM lands have, however,recently been opened to mineral exploration and mining entry. 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-7-22 - - - - - (d)Projected Demand Without the Project Projections of demand within the study area assuming the Susitna Hydroelectric Project is not constructed were calculated as a part of this Recreation Plan in order to provide baseline data.These calculations and the preparation methodology appear in Section 3.5. E-7-23 - 3 -PROJECT IMPACTS ON EXISTING RECREATION Impacts that the Susitna hydroelectric development wi 11 have on the existing recreation patterns are of two types,having either a direct or indirect effect.Di rect effects are defi ned as those whi ch rel ate to physical changes to the natural resources which constitute recrea- tion settings.Impacts to this setting might either increase or decrease the des irabi 1 ity and probabi 1 ity of exi st i ng recreation ac- tivity types and levels.They may also make possible new levels and types of activity.In many cases the direct impacts on recreation settings are synonymous with concerns for the environment expressed in the fiSh,wildlife·and botanical chapter of Exhibit E.In this sec- tion,such cases will be referenced to the detailed discussions in the corresponding sections.Indirect impacts are those related to changes in user demand levels.These include the impacts of construction wor- ker recreation and the influx of recreationalists as a result of the new road openings.This first section deals with direct impacts and discusses major project developments separately.Construction and operational impacts are also distinguished in each case. Construction of the Watana Dam and related features invol- ves construction of two cofferdams and diversion of the river.It includes clearing of forest land.dredging of the river and other borrow locations for dam fill material, blasting for the underground powerhouse and other features as well as other heavy construction activities at the dam site.In addition,an access road will be constructed from t he Denali Hi ghway and the construct i on camps bui 1t near the damsite.(The access raod is discussed in Section 3.3) The 38.000-acre reservoir area ~v.ill be cleared of trees prior to inundation.It is anticipated to require three years to fill the entire impoundment area.The primary impacts of initial construction activities extend beyond the relatively small physical areas being disturbed.An immense change in i mage wi 11 affect a 1arge part of the river basin as the prevailing ambience of an untouched, unaccessible wilderness changes to one of intense acti vity and heavy construction.This is an unavoidable impact of development and can only be partially mitigated by careful management of the remaining lands for public recreation and appreciation.Specific impacts of construction within the disturbed land areas include the elimination of small areas of wildlife habitat in the primary construction areas to the north of the damsite.This area contains.a small concentration of black bear that would be eliminated, E-7-24 ----------~_..._------'"--~-,.,"',-,.---,"''''~ therefore reduci ng hunt i ng opportunities.Some fi shi ng impacts will occur as a result of the effects of ri veri ne construction on water quality.Tsusena Creek and the Susitna itse1 f wi 11 be affected by gravel removal duri ng construction.Impacts are expected to be qUickly dissipa- ted in the Susitna River and not significantly affect recreational fishing other than precluding actual construc- tion areas from recreational use. The 38,OOO-acre reservoir impoundment will inundate 10 small river-front cabins which are used seasonally by hunters,fi shermen and other recreati oni st who arr i ve by boat or plane.The impoundment will also inundate a large area of prime habitat for such wildlife as wolverines, moose and black bear and possibly 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 either fewer hunters, particularly trophy hunters of black bear,will be attract- ed to the area or that those who do wi 11 be 1ess success- ful.Specific ilTlpacts and mitigations for this loss are discussed in Exhibit E,Chapter 3,Fish,Wildlife,and Botanical Resources. (i i)Operati ons Operational impacts on existing recreation are related to the schedule,quantity,quality and temperature of water retained in the reservoir and released from the reservoir. Withi n the new reservoir area an entirely new recreat i on setting will have been created which bears little simi- larity to the existing river recreation patterns.Opera- tions will heavily impact this new setting through water f1uct~ation schedules.During the prime recreation months of Ju1y,and August,water levels will be rising,with a peak in September. The lake shorelines will contain large mudflats and steep banks of exposed tree stumps,and slumping soils.The sit- uation will severely limit the development of the reservoir as a recreation opportunity.A lack of fish population, si Tty waters and col d water temperatures in the reservoir reinforce this recreation limitation. (b)Talkeetna to Devil Canyon Fishery (i)Construction Impacts of construction on this downstream sports fishing area are directly related to the water quality changes caused by gravel and soil dredge-and-fi1l operations in the channel.Some periodic minor modification in turbidity levels can be expected. E-7-25 ""'" - .... - Recreational fishing could also be negatively affected during the three year filling period in which summer flows will be reduced.About 20 sloughs utilized for spawning and/or rearing will potentially be impacted,and the fishing experience may be some\'1hat diminished temporarily by the lower water levels •.- (i1)Operations Potential fishing impacts after construction will also be dependent on water quality and quantity.As flows stabi- lize and as silt is trapped in the reservoir,it is antici- pated that the Sus itna downstream of the dam may cl ear up and become somewhat more fishable,particularly for coho and chinook salmon.There may be minor increases in winter turbidity between Talkeetna and the damsite,but an overall improvement in fishing opportunities is anticipated. (c)Other River-Related Recreation (i)Construction The existing level of boating activity both downriver from Devil Canyon to Ta 1keetna and upr i ver from Watana wi 11 be largely unaffected by Watana construction until actual fil- ling of the reservoir begins.At that time,water levels downstream will decrease in summer recreation months. Depending on the precipitation and natural water level dur- ing filling,the reach of the Susitna one to three miles below Sherman (about six to nine miles below Gold Creek) may be diffi cult to navi gate.Boaters who currently ven- ture up the ri ver to Devil Canyon and Portage Creek may find this difficult to do.Rafting and kayaking from upri ver will be restri cted duri n9 constructi on for those few users who currently raft down the Susitna and pullout in the area of Stephan Lake and for the very small group of kayakers who run the Devil Canyon Rapids (40 in 5 years). During construction,these boaters will have to portage the construction area.This obstacle will significantly affect the wild river experience,even though the actual.length of river where construction is in sight and sound is short. - (i i )Operat ions Downstream boating may continue to be affected by reduced water flows after construction.Water levels wil1.be lower at Gold Creek during June,July,and August.Sunshine and Susitna further down the river will be much less affected. E-7-26 ------""""'_....~-_.._------._...._,--~---- Continuous river trips by kayakers or rafters who float down to a take-out below Stephan Lake or go on through Devil Canyon will be e1 iminated as portage around the Watana Dam would be difficult.Upstream the float trip will change from a river to a lake experience as the reser- voir backs 54 miles up the river valley.With a loss of r api d ri ver water movement,boaters will need manual or mechanical propulsion to navigate the new lake.New acti- vities such as float planing and large motorized boats will increase as recreationists take advantage of the recreation setting created by the lake and the new access through Vee Canyon.The experi ece \'Iil1 be quite qifferent in character and can be expected to attract a different clientele than the present users. A major impact of thi s new reservoir is the loss of the existing pristine riverine setting.The aesthetic experi- ence for future boaters vii 11 be greatly deteri orated by the effects of water fluctuation on the new shoreline.These visual impacts such as mudsl ides,mudflats,etc.are dis- cussed in Exhibit E,Chapter 8,Aesthetics.Safety will also be a concern for future boaters using the lake as the great 1ength and breadth of the impoundment may l.ead to treacherous conditions for small craft in high winds. (d)Other Land Related Recreation (i)Construction The land-based recreation activities and resources within areas that Watana construction will effect have already been modified by the presence of project researchers who currently live and work in the vicinity.However,their low level recreation activities have not caused adverse impacts. It is anticipated that during construction all land areas associated with this project will be closed to the recrea- tion public.Thus any existing activities and resources will be eliminated for the duration of construction activi- ties. Existing recreation activities consist of hunting and fish- ing in the area;these activities can easily shift to other public lands for the duration of work.However,if con- struction practices cause permanent degradation to the recreati on environment or the fi sh and wi 1dl ife habitat, the activities could be lost permanently. E-7-27 .- -. ~, .- .- .-r - (i i)Operat ions ~ter construction the land areas associated with the dam oJffll either be rehabil itated or util ized for operations facil ities and a permanent townsite.The rehabil itated areas may return to use as natural recreational areas.The operations areas,however,will continue to be unavailable for pUbl ic recreation use.The presence of workers and their families will also continue to impact the recreation resources.Ho\'/ever,with proper control by land owners and managers,these effects will not be detrimental. 3.2 -Devil Canyon Development (a)Reservoir (i)Construction Construct i on of the thi n concrete arch Devil Canyon Dam related features involves construction of a high-level bridge across the canyon,cofferdams and diversion of the river,land clearing and blasting,and a major concrete mix plant at the damsite.In addition,a railroad spur will be constructed from Gold Creek,a road \'1111 be built between Watana and Devil Canyon,and construct i on camps will be built near the damsite.The 7,800-acre reservoir itself is located within a steep canyon and will require less c1ear- i ng than the Watana reservoi r.As at Watana,the pri mary recreation impacts of construction will result from the conversi on of a wi 1derness area to a construction area inhabited by 1,780 single workers and 170 married workers (550 people).Construction of the 34-mi1e road connecting Watana and Devil Canyon will introduce a developed land use and access pattern into an existing wilderness area • The Devil Canyon reservoir,unlike Watana,will be rela- tively narrow and largely confined within the canyon walls, part i cul arly the downstream reaches.The major impacts resulting from its creation will be the loss of 11 miles of Class VI rapids.This is an irreplaceable loss of a scarce worl dwi de recreat i on resource.Expert kayakers have come from around the world to attempt this trip.Although the actual number 'of kayakers are few (2-3 parties per year), this does not diminish the significance of the loss.An additional 32 miles of river canyon upstream from Devil Canyon will also be lost.However,since a portage around Vee Canyon is necessary to reach this area today,it is also used by only a few recreationists. E-7-28 ------------- (i i).Operations Operationally the Devil Canyon reservoir 'ill show the same limitations that effect the recreation opportunities of Watana Reservoir,although lower drawdowns and steeper sides will result in less severe mudflats.The loss of rapids and canyon will be complete as the reservoir fills. (b)Talkeetna to Devil Canyon Fishery (i)Construction With the exception of temporary water quality impacts during construction of the cofferdam,no water quality- related recreation impacts are foreseen.Filling will only take about two months,and depending on season,will not appreciably affect flow rates.No further impacts are anticipated on downstream fishing and boating activity. (ii)Operations Operation of Devil Canyon will cause only minor changes in flows from Watana operation flows below the dam and is not expected to further affect the river downstream.Likewise, mi nor increases in wi nter turbi dity are not expected to affect recreational fishing. (c)Other River-Related Recreation During the construction and operation period of Devil Canyon Dam no other impacts are anticipated. (d)Other Land-Related Recreation Land-related recreation impacts for construction and operations at Devil Canyon dam are simil ar to those antici pated at the Watana Dam development. 3.3 -Access (a)Watana Access Road (i)Construction The 41-mil e·road from the Denali Hi ghway to the Watana dam- site will provide logistics support for construction to the dam.Construction will include a small temporary construction camp near the Brushkana drai nage and several borrow pits as material is required for construction. E-7-29 - ""'" - - The road will traverse a large area not presently acces- sible by highway vehicle.While APA proposes to reserve decision until completion of Watana construction,for the purposes of this recreation plan,it is assumed that after completion of the Watana Dam Phase in 1993 the public will be allowed to use the road to access the areas south of the Denali highway.Prior to 1993,use of the road is expected to be 20-30 construction vehicle trips per day.An addi- tional 200 private vehicle trip/days are anticipated as construction workers living off-site commute from Cantwell or e1 sewhere. The roads will be designed for a maximum driving speed of from 40 mph to 60 mph.Two dri vi ng 1anes VJi 11 be 12 feet wide with additional 6-foot shoulders on each side.Road surfacing will be compacted gravel. Within the proposed road corridor,existing recreation con- .sists of dispersed and low-level activities such as hunt- .ing,fishing and hiking.During construction of the road these patterns will be somewhat impacted by increased ac- tivity and disruption to the environment.However,due to t hei r inhere nt mobi lity and non-site specifi city,these activities will temporarily be absorbed by the surrounding 1and. More important than this are the impacts that the construc- tion activities and increased numbers of people on site wi 11 have on the natural resources which constitute the activity setting.Within the 100-foot corridor identified for the road,the recreati on setti ng 1 s major components consist of fish and wildlife habitats and visual quality of the landscape.Specific impacts and the guidelines for protection of these areas are discussed in Exhibit E, Chapter 3,Fish,Wildlife and Botanical Resources,and Chapter 8,Aestheti cs.Current road ali gnments ~<Ji 11 adversely impact sensitive wetlands and fish-streams of the Brushkana,Soule,and Deadman Creek drainages. {ii}Operations In 1993 if the road were opened to the pUblic,it is anti- cipated that in addition to the attraction created by the new dam and reservoir,additional hunters,fishermen, sightseers and other recreat i oni sts wi 11 be attracted to the newly opened lands.The Recreation Plans as presented in Section 5 is intended to focus this new influx of users to allow them to utilize the new recreation opportunities created. E-7-30 (b)Devil Canyon Access Road (i)Construction This 34-mile road connecting the Devil Canyon damsite 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 con- struction site.The road traverses more difficult terrain than the Watana access road,and as a result,requires careful design guidelines to control potentially signifi- cant impacts caused by large cut/fill sections.The selec- ted road corridor will also affect the private recreation lodg~at High Lake.Passing within a mile of the develop- ment,the new access will change the character of the faci- 1 ity from a remote fly-i n retreat to a more auto-ori ented commercial facility. Several borrow areas will be required to construct this road section.Impacts that these excavations and the road path itself will have on the existing recreation resources are primarily visual;thus,specific mitigations are dis- cussed in Chapter 8,Aesthetics. (ii)Operations After construction work is complete in 2002,Devil Canyon road may be opened to the public.Operations personnel will also continue to travel to the Devil Canyon Dam from the permanent towns ite at Watana.Devil Canyon Dam is expected to become more of a tourist attraction than Watana because of its striking design and impressive setting.The road will functi on as an important recreation faci 1 ity in that regard.The impacts of the public in this corridor area are similar to those for the Watana access road. (c)Gold Creek -Dev;l Canyon Railroad (i)Construction The construction of the rai lroad spur to the Devi 1 Canyon Damsite will have little effect on existing recreation patterns.The areas which it crosses are largely unused as a recreation resource.As with the case of the road con- struct;on,care must be taken not to degrade the exi st i ng recreation setting.This involves protection of the shore- 1 i nes of the Sus itna and streams crossed by the tracks as they constitute both fish/wildlife habitats and aesthetics resources.Potenti al sources of impacts include:major cut/fill operations,borrow excavation and stream cross- ings.Impacts and mitigations for these issues appear in the Fish,Wildlife and Botanical Resources and Aesthetics Chapter 3 and 8. E-7-3l - - - - - I~ (ii)Operations After construction is completed at the Devil Canyon dam- site,rail service will no longer serve an exclusive pro- ject function.At this time it may become available to the publ ic use.As such it will constitute a positi ve impact On r.ecreation use.It has the potential of providing recreational access into the project area within four hours from Anchorage compared to the a1ternat i ve road access i""'"which will take seven hours.It is likely that demand woul d not be hi gh enough to provi de thi s servi ce without some subsidy however • .(d)Other Land-Related Recreation (i ) (i i ) Construction The primary areas of construction and related construction areas support numerous game animals.The noise and dust of constructi on and the di srupt i on caused by heavy equi pment operat ions along with the presence of 3,600 constructi on workers will disturb the habitats of area wildlife.Care- ful pl ans shoul d be made to contai n the areas of di srupt- ion,the result from construction activities,and increased human presence to prevent unnecessary degradation of the adjacent recreation environment.An important impact will be the introduction of civilization into an essentially wild area.It is anticipated that all hunting by project personnel wi 11 be prohi bited.Fi shi ng activity will be managed by the State Department of Fi sh and Game.For pur- poses of enforcement,it is likely that all recreation access,by project personnel and the general public,will have to be managed during construction.It is likely that some areas now utilized for hunting and fishing by persons using floatplanes and all-terrain vehicles will be managed more restrictively during construction than at present. Operation During operation,only a few hundred people will reside in Watana village,and personnel and operation/maintenance activities will have only a minor impact on recreation resources. 3.4 -Transmission - (a)Project Area Construction of the east-west connection from the powerhousesdams to the Intertie will be done primarily in winter,except for the western portion from Gold Creek to an unnamed creek south of the Susitna Ri ver about four mil es west of Devil Creek,where a E-7-32 ,__--__...---~..•---_.M _ pioneer road already exists.No impacts are anticipated on the existing recreation patterns either during construction or during operation of these lines. (b)Intertie and Stubs Intertie construction is scheduled to begin in 1983.These lines and the future stubs from Healy to Fairbanks and from W"illow to Anchorage are not anticipated to effect existing recreation patterns during construction.Cleared transmission corridors are commonly used by hunters and hikers and to the extent that these activities take place,recreation will be positively impacted. Future studies are planned by APA to develop a recreation plan related to these corridors. 3.5 -Indirect Impacts --Project-Induced Recreation Demand (a)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 1ocat i on,the characteri st i cs of the pro- ject and the construction schedule.Added complexities result from historically unpredictable regional growth pattern and lack of consistent and verifiable data concerning regional recreation projections.Some of.these circumstances include: -Alaska Recreation Environment.As discussed in Section 2 of this Report,recreation in Alaska has unique characteristics due to the size of the state,the sparse population,the lack of roads and long distances between facil ities.The untouched wilderness conditions and abundance of wildlife have attracted new state residents who enjoy the primitive recreation experi- ence.Recreati on patterns and uses do not fo 11 ow those common at many hydroelectric projects in the lower 47 states.Usual recreation standards are not,for the most part,applicable in Alaska. -Newness.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 preferences,demand data and so on which is usually availale to recreation planners. Whi 1e important useful data are bei ng generated by state agen- cies,the backlog of experience helpful to confidently make long-range predictions does not yet exist. -Uncertainty of Population Growth.Population growth has two components --natural growth (surpl us of births over deaths)and immigration.In Alaska,a major component of growth is immigra- tion.Growth has been dependent in the past on external causes, such as the discovery and price of oil and the \'/Orld economy, and is largely unpredictable by standard demographic methods. £-7-33 - ~, (~ - (b) -Population Mobility.A1aska 1 s population is among the youngest in the nation and unusually mobile.As energy,mineral develop- ment and construction projects begin and end,and as the large proportion of military and governmental personnel change assign- ments,the population composition changes.Public opinion and preference surveys can become qui~k1y outdated as new immigrants repl ace former res i dents.These changes may not,however, appear in total population counts,because the numbers may not reflect change in composition.Likewise,whole cy1ces can occur and be "missed ll by the decennial census. -C1 i mate.Wi ntersi n the project area are long and severe.The Denali Highway,the only ground route penetrating the area,is not maintained in winter.Landing strips and lakes used for airp1ace access are also hazardous during the winter season.In addition,the short winter daylight period decreases available time for outdoor work,recreation and travel. -Setti ng.The Susitna project area,compared \I~ith many other places in the United States,appears to be an outstanding recreati on resource.However,in compar i son with other resources in A1 aska,(with some important exceptions such as Devil Canyon Rapids),it is not unique. -Changing Land Ownership.Major portions of Alaska have histori- ca 11y been owned by the federal,and more recently,the state government.Large portions of land are currently in the process of being distributed 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 hi storica1 patterns of open recreation access to most lands within the state are chang- ing in some instances. -International Travel.Recent years have seen wide fluctuations in international travel patterns as the dollar,Mark,yen and other currencies have ~hanged in value.As a remote and somewhat exotic tourist destination,tourist recreation levels in Alaska may vary greatly according to unpredictable outside i nf1 uences. Assumptions The proposed recreation plan is designed as a mitigation for recreation opportunities due to project development,to'utilize the recreat i on opportunit i es gai ned due to proj ect development, and to provide for the demand induced by project development. In projecting demand,a number of simplifying assumptions have been made which obviate the effects of the uncertainties in A1aska1 s recreation future.In addition,to these assumptions, the recreation plan is phased and a monitoring program is proposed which will allow periodic adjustments to be made in the plan as assumptions and recreation conditions change. E-7-34 '~_._----------._-"---------_._'--- Assumptions of these demand projections include the following: -The population projections presented in Exhibit E,Chapter 5, Socioeconomics Impacts,are valid for Anchorage,Fairbanks North Start Borough and the Railbelt.Population projections for the Matanuska-Susitna Borough,as developed by the Borough in October 1982,will continue to be valid and are included by inference in the Railbelt projections. -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 drawdown schedules for Watana and Devi 1 Canyon will pertai n.The access roads from the Denali Hi ghway to Watana and from Watana to Devi 1 Canyon will be developed as currently planned.A railroad spur will be built from Gold Creek to Devil Canyon,and will be opened to the public upon construction completion.An access road will not be connected from Devil Canyon to Hurricane. -The Denali Highway will be upgraded and new facilities will be ("'"'I install ed,as currently proposed by the Al aska Department of Transportation.The road will be kept open in the winter from the intersection 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 and Fairbanks and other appropr i ate governmenta 1 units wi 11 continue to pursue their plans for increased recreation facilities to serve increased demand.Many of the facil i ti es documented here ~"ill be closer to population centers than the Susitna project and will accommodate a portion of future demand by city dwellers. -The Alaska Power Authority will evaluate the decision to open the access road from Watana to the Denali Highway at the time Watana constructi on is compl eted.For the purposes of th is recreation demand projection and plan,it is assumed that the road will be opened to full public access in 1993.If it is determi ned in the future that the road shoul d not be opened then,demand for recreation will be less than projected.Speci- fic elements of the recreation plan will then be deferred as appropriate through the monitoring/implementation program. -The Native corporations will pursue a course of paced develop- ment of their lands,including selected mineral development, recreation home development and commercial recreation develop- ment.These uses are assumed to be complementary to this Recre- ation Plan. -The Alaska Department of Fish and Game will adopt regulations appropri ate to protect those resources withi n the project area and appropriate to the general levels of projected demand. E-7-35 -I - ""'" -The dams wi 11 have an inherent "curi osityll val ue whi ch wi 11 attract one-time visitors.Watana,in particular,is not regarded as a major sustained attraction for repeat visitors. Devil Canyon Dam,the hi gh-l evel canyon bri dge,and the ra;lroad spur have more inherent attraction as recreation potential •. Both reservoirs will be characterized by slumping side walls, scal es a nd landscapes on steep banks.Watana,in part i cul ar, will have 1arge mudfl ats in many 1ocat ions when drawn down. Neither reservoir will be an attractive recreation resource for sport fishing or boating.Watana in particular,and Dev"il Canyon to a lesser extent ,wi 11 not be attractive resources to kayakers,canoers,rafters and other small boat recreationists, due to wind,chop and temperature conditions. -EXisting private lodges will continue to operate in a manner and scale similar to 1980 operations.While some changes undoubted- ly will take place,they will not be of a scale to influence demand projections significantly. -The Alaska Railroad will continue to operate as a passenger recreation facility,with daily whistle-stop service in the summer season and weekend Whistle-stop service off season. -Whil e there will cont i nue to be select facilities,the project recreation attraction and will international tourist attraction an international clientele for will primarily be an "in-state not be a major national or such as Denali National Park. (c) -Because of climate,winter darkness and distance from population centers,the project will be primarily a summar (mid-June to mid-September)recreation resource. Estimated Recreation Demand Ava il abl e recreati on studi es were surveyed and eval uated for applicability to the Susitna Hydroelectric Project.A wide vari ety of non-comparabl e and to some extent di sparate data were found.A series of per capita participation projections developed by the U.S.Soil Conser¥ation Service for the Susitna River Basin Study (John OINeill,November 1978,unpublished)were chosen as the most appropriate methodology and assumptions for this recre- ation plan.That methodology and major portions of the base data employed in that projection are used and referred to as the "per capita participation method".The projections have been modified for purposes of this Recreation Plan by updated population data and projections.Allocations of regional recreation demand de- 'rived 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: E-7-36 -Willingness to Drive Comparison -Denali National Park Comparison -Denali Highway Travel Comparison -Opinion Survey Comparison (i)Per Capita Participation Method This method was developed by the U.S.Soil Conservation Service and applied to the 13-million-acre Talkeetna Subarea in 1978 as part of the Susitna River Basin Coopera- t i ve Study,a joi nt effort with the A1ask a Department of Natural Resources,the Alaska Department of Fish and Game, and other cooperating agencies.The method utilizes em- pirical participation rates for eight outdoor recreation activities and applies them to existing population figures. The demand projection presented in thi s report uses the general methodology and recreat i on data developed by S.C.S.The actual calculations presented herein,however, were performed by the Susitna Recreation Pl an Study Team s pecifi ca lly for this study.The pl anni ng year 2000 was chosen for conveni ence and comparabil ity as the future demand project time.Assumed percentage increases in annual partiC"ipatiol')days are utilized,as well as year 2000 population projections.The following formula was utilzied to estimate 1980 recreation demand: TOTAL 1980 POPULATION X AVERAGE ANNUAL PARTICIPATION DAYS =TOTAL DEMAND IN USER DAYS To estimate 2000 recreation demand: TOTAL 2000 POPULATION X AVERAGE ANNUAL PARTICIPATION DAYS X ASSUMED PERCENTAGE INCREASE IN PARTICIPATION = TOTAL DEMAND IN USER DAYS This procedure is followed for each of eight separate ac- tivities.Populations used are shown in Table E.7.9.Rec- reation participation is shown in Table E.7.10. Both participation days and assumed increases are taken directly 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,average annual participation days per capita were not provided in those reports.While newer data,if avail- able,would have been preferable,it is assumed that the projected increases in participation published in the 1970 Pl an are suffi ci ently representative for the purpose at hand.Comparisons of the activity participation rates which appear in all three plans support this assumption. E-7-37 - - - - - - -"----- The River Basin Cooperative Study utilizes the travel cost method,which is based on the premise that other things, being equal,per capita use of recreation sites will decrease as travel time and cost increases.This appears to be generally true according to empirical data in Alaska. The data base employed di stri butes the sum total of tri ps withi n gi ven hourly dri vi ng times.For the Susitna Hydro- e1ectri c Project,dri vi ng times,distances and percentage of trips are shown in Table E.7.11.The total demand previously calculated is multiplied by these percentages for each trip origin.Note that for this study (unlike the River Basin Study which uses actual mileage distances in the Willow subbasi n)Mat-Su Borough fi gures are used to represent popul ati on between Anchorage and Fa irbanks,and an assumed centroi d of Mat-Su popul ation was chosen for calculation purposes.While the potential market area for project recreation demand undoubtedly exceeds these areas, it is anticipated that population growth rates and demand percentages are sufficiently conservative to adequately represent maximum demand. The centroid of the project recreation area is assumed to be 10 miles north of the Watana damsite,determined by observation.Table E.7.12 gives estimations of total recreation demand (in user days)for all recreation sites within 250 miles (or 5-6 hours)of Anchorage,200 miles (or 4-5 hours)of Fairbanks,for the population of Anchorage, Fairbanks,and Matanuska-Susitna Borough.It is important to note that these demands are for all sites withi n the given time-distance,not specifically for the Susitna hydro site.For instance,other sites 5-6 hours 'drive from Anchorage could include those south on the Kenai Peninsula or east in the Wrangell Mountai ns.Ti me-di stance factors are based on empirical evidence as developed by S.C.S., whereby the number of trips in each hourly travel band is estimated as a proportion of the whole.These estimates were calculated separately for each type of recreation activity using the population given in Table E.7.9,the factors in Table E.7.10 and the distances in Table E.7.11. Table 7.13 summarizes these demands.In order to apply total demands to the Susitna Hydroelectric Project Recre- ation 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 south of the Susit- na River on the south.This area was determined based on the areas directly affected by development,known recre- ~tion resources of the area and the recreation opportuni- ty settings determ·i ned by the study team in the fi e1d. E-7-38 It also takes into consideration Alaska Department of Fish and Game Management subunits.Si nce those units relate to big game (moose)management areas and not human recreation areas,it was neither necessary nor desirable to correspond exactly to those boundaries. -Alaska Department of Fish and Game 1981 Geowonderland hunting statistics for moose,caribou and Dall sheep were reviewed.These data indicated that in 1981,fewer than 700 hunter days were spent in the area.Only data for the hunting year 1981 were available for review.There- fore,in order to be conservative it was assumed that the existing condition is 800 hunter days.Table E.7.14 and Table E.7.15 show assumed existing (1980,for simplicity) use of the area in numbers of recreat i on days and in percentages of the total days given in Table E.7.13. -It was assumed,based on observation and personal conver- sations with informed local sources,that there are cur- rently 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 con- nected with the project area in terms of recreati on setting identity.~ -Assumptions of current sport fishing were made from in- .terpretati ons of the Al aska Department of Fi sh and Game Statewide Harvest Study (1981 data).This report lists angler days for 1977 through 1981.Data include the number of anglers resident in the upper Copper/Susitna River area who fish in all locations.This number is decreasing from 1,885 in 1977 to 1,195 in 1981.Charts of the number of angl er days fi shed in the West Cook Inlet/West Susitna drainage and the East Susitna drainage show that these figures have generally decreased over the last four years.The level of fishing in this area as a percentage of statewide fishing has also decreased. -Whi 1e these data do not directly correspond to the pro- ject area,in combination with personal conversations with knowledgeable local sources,the project team esti- mated 1,500 angle days/year to be in the area.Fishing activity is assumed to be quite low in the areas because it is inaccessible by auto and has no salmon runs except on the Susitna River below Portage Creek and on Prairie Creek. -Number of user days were assumed to be 4,000 at the only developed campsite in the area.The BLM camp at Brush- kana Creek on the Denal i Hi ghway was 33 campsites and is reportedly at capacity duri ng hunti ng seasons.The assumed current numbers represent a capaci ty use,wit h three persons per camps ite,duri ng a month-long hunting E-7-39 - season.Two addit i ona 1 months of capacity use,with two persons per campsite,were calculated for the weekends of the other two summer recreation months. -It is assumed that there is essentially no hiking or picnicking occurring in the area that is not associated with other activities such as hunting,fishing or camp- i ng.As hiki ng trai 1s are not ri gorously desi gned for specific capacities at the primitive level of design anticipated,and as picnicking in this remote area is most frequently associated with camping,this simplifying assumption is appropriate. -Cross-country sk i i ng is known to exi st in the Chul itna Mountains south of Cantwell,and 100 user days have been assumed for the study area. As indicated in Table E.7.15,it is calculated that ap- proximately 6,700 recreation days per year occur in the area today.In order to project the future user days for the area if the Susitna Hydroelectric Project is not built, 1980 to 2000 population growth rates (Table E.7.9)and increased participation rates (Table E.7.10)are applied to the 1980 usage.That is,usage in the year 2000 will increase as does population and propensity to recreate, given no other actions such as construction to access roads into the area.This simplication do~s not take into consi- deration the changing attraction values of other recreation opportunities in the state.Those woul d be assumed to cause a decrease of demand at Susitna and therefore rei n- force a conservative estimation. In the case of the future camping estimate at developed campgrounds,a different procedure was followed.Whi le demand,as calculated above,shows an increase to 9,700 user days,it is typical for campground supply to lag demand for the unaccommodated increment to go to unde- veloped sites.The BLM Denali Block Management Plan calls for three three-unit pull-offs in the area,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 recreation demand in the year 2000, assuming the Susitna Hydroelectric Project is built,the baseline (without project)recreation growth rates shown in Table E.7.14 were examined.and compared with project impacts as described in Section 2.In addition,the team1s E-7-40 knowledge of the project area derived from a careful recre- at i on opportunit i es assessment and study of a lternat i ve opportunity was applied to the area. -For big game hunting,increased road access will lead to an increased activity.The 1981 Geowonderland data base indicates that most hunters currently fly into the area. Because the resource is limited and regulated,a maximum increase of 0.2 percent is assumed (from today's capture rate of 0.3 percent of total demand in the hourly inter- val to a year 2000 capture rate of 0.5 percent).(See Tables E.7.14 and E.7.15.) -No waterfow·1 hu nt i ng increase over basel i ne fi gures is anticipated as no proposed project features will affect the waterfowl hunting lakes. ~Presently freshwater fishing is very limited due to lack of automobile access.Most exist;ng fi sheri es sites are used principally by fly-in fishermen.It;s assumed that this demand like hunting will increase 0.2 percent, attacting.approximate1y double the number of fishermen as in the base case and triple the current use. -Developed campground demand is a funct i on 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 objective of protecting the natural resources, demand is expected to be directed toward small primitive campgrounds.Demand is anticipated to be limited to an additional 4,000 to 6,000 visitor days per year. After the Susitna project is completed,part of the river resource for canoeing and kayaking,and in particular the important Devil Canyon Rapids,wi11 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.sk ii ng 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 visitor days per year are projected for post-project conditi ons in the year 2000.The Recreation Plan has been developed to accommo- date thi s growth,phased to the Watana and Devil Canyon portions of the project.Other recreation uses,such as driving and sightseeing,are assumed to be included in E-7-41 - - ..." this estimate.This appears to be a reasonable assump- t i on because recreat i on demand often takes 10 or more years to build up after facilities are developed and the curiosity value of the project is assumed to wane over time. (ii)Willingness to Dri~e Comparison The Alaska Public Survey (1982)indicates that 20 percent of the population is willing to drive five hours to a week- end recreation opportunity,and an additional 11 percent will drive six or more hours.Applying these data to the projected year 2000 population (.31 x 450,570),it can be estimated that approximately 140,000 persons from the Rail- belt,Anchorage and Fairbanks could be attracted to a site the di stance of the study area ina si ngl e year.Assumi ng a captor 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. (iii)Denali National Park Comparison The entrance to Denali National Park is about 80 highway miles from the Watana site.With Mt.McKinley,North America1s largest mountain,the Park is a world-renouned recreation attraction.In 1981,the ara attracted 256,500 recreation visitors and has shown generally a high rate of increase since the Parks Highway was opened in 1971.(See Table E.7.16.)While the National Park Service has not projected visitation to the year 2000,the Denal i State Park Visitor Facility Market Analysis and Economic Feasi- bil ity Study (Al aska Department of Natural Resources,June 1,1980)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 recreation 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 visitors drawn to the national park.If,after project development,it were to draw,for example,10 percent of the visitation of the national park,that would be 51,000 in the year 2000.This too is similar to that estimated in the per capita participation method. E-7-42 ~---_._-------_.-~---------------~---------- (iv)Denali Highway Travel Comparison Because the primary access to the Susitna recreation area will be via the Denali Highway,comparisons can be made up to e lsting and future recreation traffic volumes along the highway.Results from a 1975 University of Alaska outdoor recreation study for the Denal i Hi ghway area (Off-Road Vehicle Use and Its Impact on Soils and Vegetation on Bureau of Land Management.Land Along the Denal i Hi ghway, Alaska:A Report on the 1975 Outdoor Recreation Survey,L. Johnson,1976)indicate that 90 percent of the highway travel ers were recreat i oni sts and that average vehi cl e occupancy was 3.2 persons.The Environmental Assessment for the Denali Highway (Alaska Department of Transporta- tion,1981)reports existing average daily traffic (ADT)on the midsections of the highway as 50 vehicle trips per day. The study projects thi s to ri se to 130 by the year 2000. 130 trips/day x 3.2 persons/vehicle x 365 days/year x .90 recreation =135,656 recreation trips per year. If the Susitna area captures 33 percent of these trips (as in Comparison ii),a total recreation demand of 45,100 trips could be anticipated.This method also has results similar to the other projections. (v)Recreation Participation Survey Method The University of Alaska and TES Inc.conducted recreation participation surveys as a part of early studies of the Susitna Project (Phase I Environmental Studies Report Sub- task 7.08 Recreation Planning,Analysis of Participation Survey Results.Terrestri al Environmental Systems.May 1982).The survey was mail ed to a random sampl e of 3,116 Railbelt residents;603 were returned by respondents,a response·rate of 23 percent.Of those who responded,148 or 25 percent stated that they currently use the study area for recreation purposes.By simple extrapolation,25 percent of the 1980 Railbelt population (284,166)is given in that report as 65,973 persons who could presently recre- ate in the area.If,however,non-response to the ques- tionnaire were assumed to be a no-use response,'as few as 14,339 persons reportedly were cons;dered to recreate there by the authors of that study.Based on detailed knowledge of activities in the area,it seems highly u n1 ikely that thi s many peopl e recreate there (see Table E.7.15),and that the responses were skewed to "yes " repl;es from persons who recreate there and who responded in hi gher proportion than thei r proportion in the entire population.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 popul at i on growth,62,200 would recreate in the area by the year 2000. E-7-43 - - .- - - -! Estimates of future use in that study based on questions regarding anticipated future use of the project are not considered reliable due to changes in the project features since the survey and the generally unreliable nature of asking how people would like to recreate rather than how they actually recreate. (vi)Concl usi on Project demand for recreation is estimated using method (i) to be:43,520 -50,220 user days/year.In comparison, other estimates are: Based on the assumpti ons set forth in thi s secti on,and considering the variable predictability of recreation estimates for the Susitna Hydroelectric Project,project demand will be considered to be: 43,000 -50,000 recreation user days/year at the completion of the project in 2002. These are proportioned as shown in Table E.7.15 and summarized as follows: '"'"' Acti vity Big Game Hunting Waterfowl Hunting Freshwater Fishing Developed Camping Canoeing/Kayaking Hik i ng Picnicking Cross-country Skiing E-7-44 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 -~---...,-----------r--- 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 phasing and access; -Operational characteristics of the project; -Recreation use patterns and demand; -Management objectives of the interested agencies and Native corporati ons; -Facilities design standards;and -Financial obligation and responsibility of the Authority. These factors were analyzed and utilized to set parameters for the plan determination process.An iterative process of plan generation,re- finement and component selection was used to maximize congruence with these factors.The first two factors were descri bed in Secti on 1.4. The third factor was di scussed in Secti on 3.5.The remai ni ng three factors are discussed below. 4.1 -Management Objectives In addition to the Al aska Power Authority,various federal and state agencies and several Native corporations establ ished under provisions of the Alaska Native Claims Settlement Act (ANCSA)have interests in this plan. (a)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 APA 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 responsi bil ity of ensuri ng 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 benefi ci al to the state as a whol e. E..,7-45 -If development of the hydroelectric potential of the Susitna River proceeds,it is the Power Authority's goal,and its intent to achieve no net loss in fish and wildlife product i vity; -In achieving no net loss,mitigation measures that avoid or minimize impacts on existing habitat,all else being ~qua1,are preferred over other types of measures; -The base line for assessing post-project impacts and the effectiveness of mitigation measures or enhancement opportunities,;s the existing condition; -The Power Authority wi 11 work cooperati ve1y with any responsible entity to explore ways the Susitna Project can complement the fish or wildlife enhancement plans of these entities; -The feasibility report will present previously identified enhancement plans for the Upper Susitna River Basin and assess the Susitna Project's impact on the ability to rea11ze those plans;and -The feasibility report will present,as the proposed plan of development,a project con- figuration that maximizes power benefits. Concurrently,all reasonable mitigation measures,including the maintenance of sufficient river flows to avoid appreciable impact,will be identified,and their effectiveness and costs will be estimated.II To the extent that fi sh and wi 1d1 ife resources constitute a part of the recreation experience,the general intent of this policy can be imputed to apply to recreation also. In addition,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 opportunities and con- straints; E-7-46 - - - -The plan should make use of roads,materials and facilities deve loped dur i ng construct i on or a1ready ex i stent.Th is wi 11 require coordination with the construction plan and schedule. Such construction roads and facil iti es shou1 d,wherever poss i- ble,be designed to conform with final recreation requirements; -The plan shall be compatible with acceptable public safety and environmental'health requirements;. Recreation should be designed and operated in a manner such that they will not create unreasonable demands on construction operation,resources for the project,or other public services; -Various combinations of ownership and management by the state or by Native corporations may be appropriate for particular ele- ments of the plan; -Irreversible losses will be identified and reasonable mitigation and/or compensation will be provided whenever possible; An area-wide systems approach which complements existing region- al facilities and provides a balance of recreation opportunity should be taken in programming recreation activities and faci1i- ties. (b)Alaska Division of Parks The following goals are stated in the Divisionis Alaska Outdoor Recreation Plan,1981: "-Provide for and enhance A1aska l s outdoor recre- ation land base to meet the needs of present and future generations of Alaskans and visitors to the State; -Establish state and local recreation programs and respond to a diversity of outdoor recreation needs as expressed through an assessment process and based on full public participation; -Integrate outdoor recreation values and diversity of recreation opportunities and programs into coordinated interagency programs,community pro- grams,and private sector developments; -Promote and balance the development of outdoor recreation opportunities in proximity to or within urban and rural communities; -Recognize and provide for the needs of special populations. E-7-47 Strengthen the capabilities of public agencies to establish,operate and maintain outdoor recreation programs through technical and financial assitance programs; -Support the development and expansion of tourism in Alaska and its role to outdoor recreation; -Preserve.maintain.or enhance Alaska1s scenic resources,environmental quality,natural areas and cultural and historic identify;and -Foster the growth and development of a strong. central role of the State in meeting outdoor recreation needs through a system of park and recreation units and historic and recreation trail s and waterways." In addition.discussions with the Division of Parks staff have suggested preferences for the following recreation characteristics specific to the Susitna project: -Selected sites should be intrinsically suitable for 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 recreation network; Construction and operations costs will require contributions by the Power Authority;and The Division welcomes participation in the provlslon of recre- ation opportunities in the state by private entities such as the Native corporations. The Alaska State Parks S stem Southcentra 1 Re ion Pl an.February 1982.published by the Alaska Division of Parks pg.66).identi- fies one proposed acquisition which could influence the Susitna Project Recreation Plan:The Talkeetna State Recreation River. This proposal would entail legislative designation of the river corri dor,preparation of a ri ver management pl an.and subsequent development in conformance with that plan.The Talkeetna River is presently reached vi a portage from the Susitna Ri ver to Stephan Lake and Prairie Creek by river recreationists originating on the Susitna.Tyone or Lake Louise areas.Current division thought is that the objectives of this plan may be met without actual legis- lative designation.Portions of this area have been selected for conveyance to the CIRI Village Corporations.including Stephan Lake.Prairie Creek.and the upper reaches of the Talkeetna River. E-7-48 ~' - - - - ~- - - (c)Alaska Department of Fish and Game As a part of the Fish and Wildlife Mitigation Review Group,the Alaska Department of Fish and Game participated in the development of the "Susitna Hydroelectric Project Fish and Wildlife Mitigation Pol icyll publ ish~d by the A1 aska Power Authority.This policy states that it is the basic intent of the Authority lito mitigate the negative impacts of the Susitna project on the fish and .wildlife resources.1I (April 1982,Paragraph 3.1). While the Department of Fish and Game has not issued a specific forma 1 statement of objectives regard i ng project-related recre- ation,discussions involving the recreation team and Department staff have suggested the following objectives: -Protect from over-fi shi ng the trophy-c1 ass gray1 i ng popul ati on in Deadman Creek; -Protect from highway traffic dangers the Ne1china caribou herd; Mai ntai n important fi shi ng resources downstream·of 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. - - (d)u.s.Bureau of Land Management The Bureau of Land Management (BLM)is manager of substanti al federal ·1 and holdi ngs generally north of the Susitna Ri ver and along the Denali Highway.Statements ofBLM objectives are found in the agency's BLM Land Use for Southcentra1 Alaska:A Summary, September 22,1980.This plan acknowledges development of the Susitna project and the access cooridor from the Dena1 i Hi ghway which can serve to:IIfacilitate public access to the back country."Specific policy statements which can relate to development of recreation plan for the Susitna Hydroelectric Project include: -Develop a water trail on the Maclaren River downstream from the Dena1 i Hi ghway crossi ng to the Susitna Ri ver and up the Tyone River to Lake Louise; -Rehabilitate the Brushkana Campground on the Denali Highway; Develop a series of "three-unit wayside camping areas ll along the Denali Highway.(Seven are indicated,including three between Cantwell and the Susitna River.) E-7-49 Develop interpretive signs,etc.along the Denali Highway to explain natural history and archaeology; -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 activity; -Create protecti ve buffer stri ps around 1 akes and water bodi es used by waterfowl;. -Protect from fire the portions of the caribou range that have a strong lichen component; -Protect Da 11 sheep wi nter range and 1ambi ng areas from all acti- vities not consistent with maintaining the population; -Identify and protect salmon spawning areas;and -Allow saddle and pack horse grazing in the Brush/Kana Creek- Dena 1i Hi ghway and the Sus i tna Ri ver-Dena1 i Hi ghway areas upon lease application and determination of carrying capacity,in order to benefit local guides. Two off-road (ORV)study areas are designated in the project vici- nity comprising most of the BLM lands between the Susitna River and the Dena1 i Hi ghway.These areas are presently open to ORV use,as are all BLM 1 ands in the area,except Tang1 e Lakes. C1 earwater drai nage has been closed by the State Fi sh and Game Commi ss i on to mechani zed hunti ng.In addit i on,recent federal action has opened major portions of the Denali Block to mineral exploration and mining entry,which could be in conflict with recreation and wildlife objectives.The Denali Highway is cur- rently under study for possible designation as a scenic highway. Mining access has been withdrawn within one mile of the highway for this reason.If the highway receives scenic 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 the highway. (e)CIRI and Village Corporations Land ownership patterns in Alaska are unique and will have sig- nificant impacts on the Recreation Plan.Prior to statehood in 1959,most lands in the project area were owned by the federal government and managed by the Bureau of Land Management.With statehood,Alaska was allowed to select lands from federal hold- ings for patenting to the State.In 1971 when the Alaska Native Claims Settlement Act (ANCSA)was passed,this process of land E-7-50 - - ~ I 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 select- ion.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 respon- sible for managing these assets for the benefit of Native share- holders.Cook Inlet Region,Inc.(CIRI)is one of the 13 regional corporat ions estab 1i shed by the Act and has recei ved port ions of both its monetary and land entitlements under conditions of the Act.Port ions of these ent it 1ements are in turn to be reconveyed to village corporations who are currently in the process of selecting lands from the region's master selection.Villages also have their own entitlements not related to CIRI selections.Major portion of the Susitna project area have been selected by CIRI. Port ions of that area wi 11 be reconveyed to CIRI vi 11 age corporati ons.When the process of reconveyance and patenti ng is complete,the village 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 wi 11 be subject to property tax assessments. Discussions with the village corporations and CIRl have led to the following understanding of their objectives: -CIRl wi 11 defer to the vill age corporations regardi ng the devel- opment of recreation 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 recreation uses,to meet future tax liabili- ties; Native corporations want to actively participate in the recrea- tion planning,decision-making,and management process; -They do not necessarily want to lose land ownership in order to prOVide public recreation; -Pub1 ic use must be carefully managed to avoid over-use and en- vironmental degradation; -Trespass must be regulated; E-7-51 -The State must assume liability responsiblity for any project- related recreation use of Native lands;and The Native corporations would benefit from provlslon of tech- nical recreation planning assistance subsidized by the Power Authority. The Native corporations have expressed willingness to participate in a cooperative recreation planning process to assure provision of recreation opportunities while meeting Native objectives.Pos- sibilities under discussion include but are not limited to: -Ownership of recreation areas by the Native corporations and lease to the State; -Ownershi p and management of recreation areas by the Nati ve Corporations; -Ownership by the Natives and joint management by them and the State under Sec.907,Alaska Land Bank,of PL 96-487,the Alaska National Interest Lands Conservation Act; -Purchase of 1 ands by the State but facil ity management by the Nat i ves under a preferred concessi onaire or si mi 1ar agreement; and -Lease by the State of lands for project construction camp facil- ities and reuse by the Natives for recreation use. (f)Matanuska-Susitna Borough The project area is located in the Talkeetna Mountains Special Use District of Matanuska-Susitna Borough.As such,any development is subject to a permit from the Borough. The Matanuska-Susi tna Borou h Coastal Mana ement Pro ram (Draft, September 1,1982 ,includes the Susitna River up to Devil Canyon where the river ceases to be navigable from downstream,and the Talkeetna River south of the study area.The Devil Canyon damsite is designated a "potential"Areas l\.1eriting Special Attention(AMSA) in that document.Under Alaska statute,should the area be desig- nated an AMSA,a proposed management scheme would have to devel- oped 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 established in the Borough.None are identified in the immediate vicinity of the project area.The Borough does not manage any recreation areas, but rather parti ci pates in joi nt pl anni ng with the State Depart- ment of Natural Resources.In some instances,they have provided lands and monies to the State for park development. E-7-52 ...... - - - (g)Alaska Department of Transportation The Alaska Department of Transportation (DOT)utilizes the Ameri- can Association of State Highway Officials (AASHO)Geometric De- sign Guide for Local Roads and Streets,November 1970,as desTgn standards 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 proposing the upgrade the Denal i Hi ghway between the Richardson and the George Parks highways.A need for improvements has been identified on the basis of a traveler survey,numerous interviews and predicted future traffic,and on significant inter- agency coordination.,Upgrading 134 miles of roadway will correct roadway structure deterioration and substandard elements and will accommodate recreat i ona 1 use demand along the hi ghway.Pr oposed project activities include minor road realignment and widening, pavi ng and pavement repair,bri dge and cul vert repl acement,.and turnout and stream access improvements.No relocation was con- sidered necessary in the location and environmental impact studies done in 1981. 4.2 -Facilities Design Standards State of Alaska,Division of State Parks for the proposed recreation facilities. operat i ona 1,manageri a 1 and mai ntenance State Park management. design standards will be used This is intended to minimize costs of the facil iti es for 4.3 -Financial Obligation and Responsibility of the Alaska Power Authority Financial commitment is related to numerous tradeoffs to be made by the Authority in terms of satisfying,with limited resources,the needs of many concerned user groups.This commitment varies with the number and complexity of other factors addressed within overall project plans and must be viwed in light of these and general project goals..However, Alaska Power Authority,as a state agency,has stated that it will provide for the public interest and implement an appropriate recreation plan.The ultimate responsibility and obligation for development, operation and maintenance of the recreation facilities relative to the project rests with APA.The Al aska Department of Natural Resources expects the licensee to be responsible for meeting initial and future project-related recreation needs for the duration of the license. The extent and nature of the licensee's responsibility will necessarily be dependent upon the conditions of the FERC license.In the event that the recreational needs within 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 plan.The cost for providing for changes and the level of financial and operational responsibility between the parties concerned will be negotiated at that time subject to approval by FERC. E-7-53 - - - - ..... 5 -RECREATION PLAN 5.1 -Recreation Concept (a)I ntroduct ion The intent of this Recreation Plan is to satisfy recreation demands created by hydroe 1ectri c development and to accommodate public use and access of the project areas.The Plan offers compensat i on for recreation opportunities lost as a result of development.It does not attempt to exactly dupl icate or replace these opportunities.The Plan is also intended to fit within the framework of regional recreation opportunities and to provide additional options.The proposed Plan accommodates these diverse recreation concerns in a manner which fits the inherent opportuni ties and constrai nts of the study area 1andscape and protects its scenic,cultural,and environmental qualities. The Susitna study area is rich in special large-and small-scale landscape settings and features.It includes wooded stream valleys and gorges,tundra and muskeg landscapes,and mountainous glaciated terrain filled with lakes,bogs,waterfalls,glacial, and many other special features.These landscapes al so offer a wide variety of plant communities and wildlife inhabitants.This area has great potential for a wide variety of recreation uses. The recreation concept was formulated to take advantage of these opportunities and the best natural features of the Susitna Basin rather than respondi ng only to specifi c project faci 1 it i es.The Plan,therefore,encompasses lands beyond the project boundaries. In fact,after analysis the highest quality recreation opportunities were found to be in the diverse landscapes adjacent to the reservoir sites and not at the reservoirs themselves. (b)Public Input During earlier studies of recreation needs for the Susitna project the University of Alaska distributed a Concept Plan Survey to the public in order to solicit public input into the recreation planning process.The questionnaire pertaining to public preferences for activities and level of development as well as thelr perceptions of recreation potential in the project area were mailed to potential users in Anchorage,Fairbanks,and other areas of the Railbelt.An abbreviated form of this was also used at public workshops to gain additional information regarding public interests and desires regarding recreation development. Early concept plans were incorporated into these questionnaires which do not reflect later engineering and schedule planning decisions and project modifications.However,those survey E-7-54 portions which identify publ ic recreation opportunity spectrum preferences continue to be valid and these identified preferences serve as the framework of the proposed recreation plan. The 2,145 survey 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 -mi nima lly 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,Fairbanks,and other railbelt)and by residence classification (urban,rural,remote rural,and other)but no signif.icant 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 primi- tive development having only limited access within a managed wilderness area. Further analysis of the attached comments indicated that facili- ties should be developed and managed on an as-needed basis, starting with minimal services and expanding only when demand warrants it.This preference has been reflected in the proposed phased implementation program. (c)The Concept The recreation concept was developed after a careful evaluation of the recreation opportunities and constraints within the study area,regional recreation concerns,and estimated demands.It also utilizes information gained from early public participation programs,and recognizes that the Division of Parks number one pri ority is the development of more trails in the State.A principal objective of the recreation concept is to help meet this priority in appropriate portions of the project area. The resulting concept provides for a challenging variety of acti- vities and experiences within a development range from natural wilderness to semi-primitive recreation facilities.Road and access has been 1 imited.Other options such as airplane,boat, train,and foot access are also provided to certain areas.Off- road vehicular use will continue in existing BLM areas. E-7-55 - -. - """" Trails as proposed in this Plan,meets the Division of Parks "Priorities Trails"standard.They are intended to have an 18"-24"tread surfaced in the parent material,with half logs in wetlands.They would be brushed out to 48"where necessary. They would be hand constructed and following existing topograpy. Development focuses activity on a core of recreation facilities and diverts the greatest number of users away from sensitive operations or environmental areas.Hydroelectric facilites which have appeal as a recreational resource have been incorporated into this concept. A primitive undesignated camp does not eV1Slon any developed hardened sites,but rather signifies the estimated carrying capacity of each site.Shelters are log structures of a design prepared by the Division of Parks. The concept also cons i ders the comp 1ex recreat i on needs of the temporary construction camp workers and ultimately the permanent village.At these locations the concept is intented to provide a variety of highly developed recreation facilities,both indoor and outdoor,whi ch wi 11 sati sfy demands without over-taxi ng the area1s limited recreation capacity. 5.2 -Recreation Opportunity Inventory The site inventory includes three steps to define the recreation resources inherent to the site; -Attractiveness (physical description); -Recreation preference type;and -Accessibil ity. The aim of the approach is to inventory the 1and base of those 1and- scapes which support the most diverse a range of possibilities. Attractiveness is a measure of a landscape1s unique or special settings and features.These can be both cultural and natural •.However,they are almost exclusively natural within this study area.The landscape was i nventori ed for features,thei r frequency and si gnifi cance,whi ch bear on the potential for recreation~The natural featues and their typical characteristics which were determined to be important in the study area are as follows: Mountaintops:rocky,craggy,often snow-capped,usually above tim- berline,glaciated or glacier forms most unique and impressive; -Tundra 1andscapes:tundra 1andscapes,both wet and dry,with close- up beauty and photographic resources; -Lakes:naturally occurring,degree of enclosure,habitat,formation, glaciated lakes and beaver ponds most unique; E-7-56 Rivers:glaciated,ruggedness and enclosure,quality expressive of Alaska,size,edges; Streams:character,clarity,size,edge;.... -Water features: ice; waterfalls,cascades,beaver ponds,snow-fields,--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 sett i ngs. The proCedure for the inventory of the land base and the analys is of the intrinsic recreation potential of the sites was as follows: (a)Review an planimetric information,USGS quadrangles,previous inventories and aerial photographs. (b)Locate the occurrence of all attracti ve features as understood from (a),.and including local knowledge and previous work, (e.g.,the recreation plan published in Phase I Environmental Studies,Subtask 7.08 for the Susitna Hydroelectric Project,May 1982)• (c)Field check all sites located in (b)plus new potential sites, using the inventory shown in Appendix B.Define the quality and extent of the various landscape features. (d)l"'lap all features and settings depicting of the distribution and location of the recreation resources.Included are indications of special or significant views and vistas.(See Figures E.7.8, E.7.9,and E.7.10--Recreation opportunities and constraints.) (e)Hunting,fishing,and collecting sites are not specifically located or symbol i zed.The opportunity ex i sts to experi ence the wildlife in many ways as they naturally inhabit the entire land- scape. A principal objective of the Recreation Plan is to provide a variety of recreation activities within a spectrum of recreation "preference types"(USDA Recreation Opportunity Inventory and Evaluation).The preference types in relate to the character and quality of the existing land base.The recreation activities also relate in terms of their appropri ateness to a part i cul ar sett i ng.Patterned after the USFS Recreat i on Opportunity Spectrum (ROS)approach,the four recreation preference types used in this report are: £-7-57 ..... - active-appreciative:natural,unmodified environment,a intellectual or physical challenge;seeking solitude; stimulation.The landscape setting should be remote, people,with a stimulating natural environment; source of aesthetic devoi d of -active-extractive:natural or semi-primitive environment,a source of enjoyment of settings which provide fish or game species,rocks, edible plants,etc.The landscape setting should be natural,removed from human influences,and difficult to access; -passive-appreciative:semi-primitive,1 ightly developed locations, natural surroundings,a source of relaxation.The appropriate physi- cal settings are natural-semi-primitive sites,with relatively easy access;and -developed:man-made developed sites,with easy access.The appro- priate 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: -active-appreciative:mountaineering,kayak-canoeing,backpacking, hiking,snow-shoeing,ski touring,nature study,and photography. -active-extractive:backpacking,hiking,photography,nature study, big game hunting,fishing,rock hounding,berry picking,and plant gatheri ng. passive-appreciative:car camping,pleasure driving,boating, lodges,snowmobiling,hiking/walking,and picnicking. -developed: driving. sports,snowmobiling,tours,picnicking,and pleasure Another major consideration is accessibil ity.The study area is very remote and must be considered as such in evaluating demand.A related consideration is the competition for the recreation user within the same framework for "remoteness'l from such pl aces as Denal i National Park,the Wrangell Mountains,the Chugach Mountains,the Alaska Range, and the Kenai Peninsula. 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 "access"new areas to the auto-related recreationist which were before inaccessible except by less convenient modes.Appropriate access to the various settings is important in maintaining the setting prefer- ences,e.g.,active-appreciative activity preferences need to be away from road access.This relationship is determined during the on-site field review. E-7-58 -------_._~-------- 5.3 -Recreation Opportunity Evaluation The major considerations for the evaluation of the recreation resources are: -Physical characteristics; -Relative scarcity; -Inherent durabi 1 ity; -Visual quality; -Carrying capacity;and -Present land status. (a)Physical Characteristics The physical characteristics of a site are those site features and settings which define and describe the site.These characteris- tics establish the relationship of the site1s own experiential potential to the regional opportunities available. (b)Relative Scarcity Relative scarcity is an extension of the physical characteristic1s relationship to the regional and local scales.The sites were evaluated on an on-site basis in a three-level rating: -High:unique local resources,or state resources,symbolic of A1 ask a 1a ndscapes or carryi ng unique recreat i on potent ia 1; -Medium:moderately uncommon,expressive of local characteristic landscapes,exposure to abundant recreation resources;and -Low:commonly occurring landscapes with few features with recreation potential. (c)Inherent Durability Durability is a general measure of the physical ability of a site to absorb the impact of recreation development.The evaluation is based upon known physical data and field observation of each recreation resource site.There are four aspects to determining durability for each site as described in the following matrix: - - - - encroach- abiotic Vegetation wi ld 1ife ment durabl e rock formations upland and waterfowl rural well-drained 1owl and soil s,low-slope forest ~ gradient moderately poorly drai ned moist caribou countryside durable soil,moderate-tundra wintering slope gradient - E-7-59 Vi sua 1 quality is a measure of the sceni c 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 -Imageabil ity (rei nforcing the Al aska landscape image)and visual quality of each setting.. Unique settings and features are important to describe in terms of their quality and imageability,and are related as indicated in the following matrix: Unique Al askan Landscapes Rare or Unusual Landscapes Common or Extensive Landscapes few extraordinary features,with hi gh apparency Hi gh High Medium several special features and settings High Medium Low LowMediuml\1edi um encroachment and created landscapes Carrying Capacity Carryi ng capacity is a measure of the i ntri nsi c durabil ity of a particular place.The goal is not to reduce the experiential potent i a1 through over-use.The carryi ng capaci ty is measured by examining the site variables of size,location,degree of access, design capacities,usability,and seasonal availability.Often intensity of recreati on use is the major factor in determi ni ng capacity. (e) -- There are three categories of use intensities used in this study: (i)High--which have high impact,high number of users,formal management and control.Hi ghly developed parks,horse camps,ORV trails are examples; E-7-60 (ii)Medium--which are for smaller groups,with less accessibi- lity,small-scale facilities;campgrounds and trails are examples;and (iii)Low--which have low impacts,little or no access,minimal development.Foot trails,mountaineering sites,and undesignated camping are examples. The general carryi ng capacity of the var i ous preference sett i ngs are as follows: Active-appreciative:low carrying capacity; -Active-extractive:low,moderate carrying capacity; -Passive-appreciative:moderate carrying capacity;and -Developed:high carrying capacity. The carrying capacities of the active-appreciative,active- extractive and passive-appreciative sites were field checked on a site-specific basis.The demand is far exceeded by the capability of the resources,therefore,limiting the conflict of over-use. The above criteria are evaluated and field checked to determine the appropriate Recreation Opportunity Summary.This is a compi- lation of appropriate recreation activities as a result of the above inventory and evaluation.The selections also consider the variety and diversity of the available resources to best suit the site.The choices also integrate the recreation needs inventoried in Section 3.5 of this report. The proposed recreation facilities are determined on the basis of supporting the proposed recreation activity within the setting. They are introduced to fit withi n exi st i ng operat i ona 1 and manage- ment guidelines and objectives of the APA and the various rearranging agencies within the study area,(Sections 4 and 6). 5.4 -Recreation Plan The Susitna Hydroelectric Project Recreation Plan includes the following sites and proposed facil ities.There are three maps (Figures E.7.12,E.7.13,and E.7.14)which cover the entire study area, indicates extensive facilities such as long trails,and locate the other site-specific recreation facilities.All sites have a key letter relating to text and maps.There are eleven additional maps which depict important features of the individual recreation sites.Projects are described by their phase of development and are as follows: Phase One -Watana Construction Phase - - Key Number E D Name Brushkana Campground Tyone Confl uence with Susitna E-7 -61 - Phase One -Watana Construction Phase Key Number B A H C F Name Butte Creek Middle Fork-Chulitna River Tsusena Creek,northern half Watana Town Site Portal Entry Phase Two -Watana Implementation Phase 0 Watana Dam Site U Watana Town Site H Tsusena Creek,southern half I Tsusena Butte f~L Deadman/Big Lake J Cl arence Lake K Watana Lake Phase Three -Devil Canyon Construction .-G Mid-Chulitna/Deadman Mountain Phase Four -Devil Canyon Operation Q S R Devi 1 Creek Devil Canyon Damsite Mermaid Lake Phase Five -To be Developed only if Demand Reguires T Soul e Creek M Southern Chu 1itna Mounta ins N Fog Lakes P Stephan Lakes W Rehabilitation Sites (E)Brushkana Camp (i )Physical Characteristics An existing developed campground with 33 campsites,includ- ing picnic,fire,and toilet facilities on the Denali High- way.Although surrounded by wonderful views to the Alaska Range and its glaciers,the campground is set in a nonde- script brushy environment along Brushkana Creek.See .Photograph E.7.4.

It is of utmost importance in these cases to rehabilitate the dis- turbed environment (see Chapter 8,Aesthetics)and to allow a recovery period prior to future recreation development.It is necessary to re-create the physiographic character and indigenous plant communities as closely as possible and cr·eate new recreation opportunities,e.g.fisheries of native species,plant materials for gatheri ng,etc. These rehabil itated areas shoul d be consi dered for development up- on the completion of the 4-phased site-specific facility program. These recreation opportunities would be part of Phase Five in the recreation plan.They have not been given a specific location or preferred use,designation in order to be flexible to unforeseen demand and recreation needs. 5.5 -Recreation Plan for Construction Camps and Permanent Townsite (a)Background Because of its remote location,Alaska Power Authority is planning for sequential development of construction camps at both the Watana and Devil Canyon sites,each to be occupied for approxi- mately 8 years,by at least a part of the work force.Because the peak number of workers will be there for less than the entire con- struction period,and average work force will approximate half of the peaks,facilities ca~generally be programmed to provide fewer opportuni ties both in range and extent than those in permanent communities.Prospective workers will understand that the project entails hardship circumstances and not expect all the amenities of urban life.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. E-7-84 Operation of the camps and the length of work days and work weeks will influence both the proportion of the work force who chose to live in camp compared to those \'iho chose to live elsewhere (if that option is given)and the amounts and types of recreation re- quired.In addition,climatic consideration will require seasonal adjustments.The 1argest work force wi 11 be active from Apri 1 through October,and a mi nimum work force of 30%of that year IS peak will continue through December and January.The work pattern is planed to be four weeks on and one week off.There will be two 10-hour shifts per day,seven days per week. Current estimates by the project are that 50 percent of the workers will travel to the jobsite by project-organized bus;35 percent by pri vate vehi cl e;10 percent by project-organi zed ai r services (senior management);and 5 percent by private airplane. (Letter,M.M.Grubb to P.Rogers,September 13,1982).While some Watana workers may choose to live in Cantwell or elsewhere,it is assumed that the vast majority wi 11 1i ve at the camp and commute to their families·places of residence only periodically. This recreation plan is intended to meet the needs of construction workers in residence at the construction camps;it is not intended to address the recreation needs of workers while not at the site. (b)Project Plans - - - - Table 7.20 indicates recreation facilities proposed in the March 1982 Susitna Hydroelectric Project Feasibility Report,Vol.3. A single-status worker camp with a peak capacity of 3,600 workers and a family-status vil age desi gned for a peak capacity of 350 families.(1,120 people).The village is currently planned to be located about 1-1/2 miles north of the damsite,and the construc- tion camp another 1-1/2 miles northeast.An airfield will a1sd be developed.After construction,the vi 11 ages wi 11 be removed and relocated at Devil Canyon and a permanent townsite for 125 oper-'!"'"': ators and their families will be developed adjoining the construc- tion village.Current plans call for no pre-construction of the permanent town facilities,necessitating a duplication of facili-_ ties in the temporary village and townsite.The Devil Canyon project is p1 anned to be constructed from a temporary si ngl e- status construction camp,and temporary family-status construction vllage located about three and four miles,respectively,from Devil Canyon.The camp is planned for a peak of 1,780 workers and the village for 170 workers and their families,totalling 550 persons.No permanent residential facilities are planned for Devi 1 Canyon. The temporary camps and vil ages are designed to be largely se1 f-~. contai ned and fenced.They wi 11 have hi gh1y regu1 ated environ- ments.It is anticipated that hunting by project personnel will be prohibited and that fishing will be regulated.Recreation programs sponsered by the camp management will occur largely within these compounds. .... E-7-85 (c) The Feasi bi 1 ity Report programs major recreati on facil ites for each of the four temporary camps.Tabl e 7.18 shows the major facilities as anticipated in March 1982.Actual recreation facil- ities at the permanent town will be planned in detail during subsequent project design phases. Recreation Programming Quality of life objectives are very difficult to achieve at con- struction camps.The type,number and qual ity of recreation fa- cilities and non-structural opportunities available will be impor- tant factors in determining that quality of life,and could impact product i vity,turnover,and abil ity of the project to attract qual ity construction workers.It will also affect the number of workers who choose to 1i ve and recreate out of the camp.Other things being equal,total environmental impacts can be reduced by concentrati ng the work force in camps rather than 1i vi ng el se- where.Other important non-recreation components which will affect quality of life are design considerations such as ability to achieve privacy~which experience has shown to be as important as recreation opportunities.Color and the use of interior plant- scapes are also important.Other considerations which are mana- gerial in nature includes food quality,management styles,special event planning and holiday celebrations (See also Chapter 5~ Socioeconomic Impacts)• .Ancillary construction camp facilities are typically programmed for 1ess than peak work force because of the peak I s rel at i vely short duration.In terms of Susitna recreation~this concept is rei nforced by the fact that annual peaks wi 11 occur in the summer months when outdoor non-structural recreati on wi 11 increase the range of recreation opportunities.While the peak work force at Watana will reach 3,480 in June and July 1990,the average annual work force will more closely approximate 1,600 total workers. Only in the five years between 1987 and 1992 will the workforce exceed this average~and then only during half of the year.Fa- cilities will be completed by the 1990 peak~and therefore 1987- 1989 will incur the heaviest use.Devil Canyon construction activity will peak in 1998-2000~and facilities will have maximum use in 1997.The permanent Watana townsite wll be planned for 125 families~or 400 total population. Assumi ng that the proporti on of family and si ngl e-status workers remains constant,recreation in the Watana camps will be pro- grammed as follows: Single-Status Camp: Family Vi 11 age: 1~600 workers 160 workers (500 total population) For Devil Canyon,comparable working forecasts are: Single-Status Camp: Family Vi 11 age: 1,100 workers 110 workers (350 total population) E-7-86 Private recreational standards vary widely and are affected by location,cl imate,user profiles and other factors.Representa- tive standards,intended however to be applied to larger permanent communities,are: Population Facility Standard Softball 1 per 1,000 Tennis 1 per 2,000 Basketball 1 per 500 Pool 1 per 20,000 Center 1 per 25,000 Go 1f Course 1 per 25,000 Source:National Recreation &Park Open Space Standards (1971) Other standards use 1 per 3,000 popul at i on for softball fi e1ds. Most planners would not use as high as 1 per 500 persons for bas- ketball courts.Outdoor courts will be 1 imited by cl imate.Sim- ilarly,other·standards use 1 per 50,000 persons for a golf course.Other standards determine athletic field needs in terms of acres per 1,000 population,typically 1.5 acres per 1,000 for field sports (adults and older children)and 1.0 per 5,000 popula- tion for tennis,outdoor basketball and other sports.(DeChiara & Koppelman,1978 pp.363-5). These types of standard planning criteria are not directly appli- cable to programming for these facil ities.Some of the other factors which have influenced the Recreation Plan are the: -extreme remoteness of the site; -long duration of construction period; -extreme harshness of climate from October through April; short daylight hours in winter months and long daylight hours in summer months; - 1ang{lO-hour)work days; -pattern of four weeks on.one week off; -necessity to protect fish and wildlife from over-use;and -homogenous user profile. Current construction plans call for five essentially separate communities which will require duplication of facilities and increase infrastructure and recreati on costs.Thi s Recreation Plan is designed to provide essentially equivalent facilities for si ngl e-and fami ly-status workers.If 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. E-7-87 - ~ I - ~I ,~ (d)Proposed Recreation Plan The Recreation Plan as presented is designed for the peak year for Watana,1990-1991,and Devil Canyon,1998-2000,and will be de- veloped incrementally in the prior years,as needed.The Plan is detailed in Table 7.18. Recommended facilities take into consideration those presented in the March 1982 Feasibility Report,recent comparable experience in construct i on camp programmi ng,and reference to recogni zed sources,including: DeChiara and Koppelman,Urban Planning and Design Criteria,Von Nostrand Rei nho1 d Company,New York,1975. -Mountain West Research,Inc.,Construction Worker Profile: Final Report.Old West Regional Commission,Tempe,Ariznoa, 1976. -Myhra,David,Energy Plant Sites:Community Planning for Large Projects.Conway Publications,Atlanta,1980. DeChiara and Koppelman,Site Planning Standards.McGraw-Hill Book Company.New York,1978. -DeChiara and Callender.Time-Saver Standards for Building Types.McGraw-Hill,Inc.New York,1973. Many of these proposed recreat i on uses can be accommodated in multi-purpose space.For instance,the gymnasium can be a multi- purpose space suitable for jogging~basketball,volleyball, tenni s,badmi nton,etc.Such areas are not necessari 1y a separate building but are developed by clustering residential modules with flooring and roofing spanning the intervening space.The swimming pool can serve as the camp fire protection reservoir and as an important image generating and social gathering place.The ~club­ house~may be a separate structure or may be di vi ded into small er social groupings throughout the camp. Exterior uses likewise "do not require separate space dedicated to a particular activity but can utilize single fields for multi- purpose sports.Utilization of recreation directors is an important component both in maximizing the multi'-use potential of the facilities and in contributing to the quality of life for the residents. It is also recognized that some of the non-structural activities recommended in this plan carry liability risks for the APA."Care- ful consideration will have to be given to the tradeoffs involved between quality of life and potential risks.Potential activities such as fi shi ng wi 11 have to be carefully coordi nated with the Al aska Department of Fi sh and Game,to protect the resource. E-7-88 Other issues~such as storage of fish caught by camp residents~ have important Health Department implications.It is anticipated that no storage of fish will be permitted,nor will angler fish be cooked in camp kitchens. Further recreation planning for the camps,villages and townsite will be required as APA progresses with policy decisions regarding details of the construction program and as actual facility design is undertaken. 5.7 -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.In addition,the II no recreation facil ityll alternative was considered. (a)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. Furthermore,potenti al safety hazards for small boaters suggest that public policy not encourge use of project waters for r ecreat ion. However,if this "no development ll alternative were chosen,project objectives of mitigating recreation losses would not be met,nor would induced recreation demand due to improved access be accommodated.Not only will project roads increase access,but the reservoirs wil become transportation routes for hunters.This alternative was therefore rejected and other recreation resources, not reservoir based,were considered for development of the Plan. (b)Additional Facil ities and Development In addition to the proposed recreation plan,the alternative of additi ana 1 recreation development was consi dered.Thi s occurred in two ways;(1)additional new sites and,(2)more intense development on the proposed sites. From the inventory,several sites were considerd which had limited potential for recreation which were not chosen because of inherent limiting factors.These factors included physical characteris- tics,accessibility and recreation potential. Each proposed recreation site was evaluated for additional facil- ities.This was considered on a one-site basis for each site. E-7-S9 - - ,1fIi!l'lli\ - (c) Because recreation demand is low (Section 5),there is great fitness between the carrying capacity of the recreation sites and recreation demand.Therefore the "additional development" alternative was rejected because of not satisfying project objectives of accommodating user demand,and appropriate levels of recreation development. Other Access Route Alternative Many access route a1ternat i ves have been consi dered by proj ect designer for access to the Watana and Devil Canyon damsites.The proposed recreation pl an and subsequent phas i ng has been deter- mined considering accessibility as a major determinent.The difference between the proposed recreation plan and another access plan would be in the phasing order of the various recreation 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 deve 10 pment.If the nort h (east-west)access route were developed,sites along it (e.g. Mermaid Lake)would be moved from Phase 4 to Phase 2 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 4 when the railroad would convert to recreation use. As part of the Phase 5 monitoring,new sites might be located if demand warrants. -- (d)Future Additions Because of uncertainties in both recreation demand and other fac- tors such as ultimate land ownership,flexibility has been built into the Recreation Plan.(This is more completely discussed in Section 6,Plan Implementation.)Future additions may be selected from the Phase 5 projects which 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 Phase 1 through 4 not be available due to land ownership or other reasons. E-7-90 6 -PLAN IMPLEMENTATION 6.1 -Phasing Phasing of the proposed Recreation Plan is dependent upon a number of factors,including: -The schedule on which Watana and Devil Canyon projects are actually implemented,including dates as which reservoirs are filled and dates at which project access roads are opened to the public; Agreement among APA and the various parties on the schedule of provi- si on of those recreation areas whi ch are not dependent on access roads utilized in project construction; -Agreement among the various parties on a recreation schedule.This schedule is expected to meet and possibly exceed FERC requirements for provision within three years,due to the extent of the project area,the extensive nature of recreation activity in Alaska,and the extremely long and phased construction period; Sat i sfactory and timely agreement among the agenci es and pri vate landowners regarding possible recreation features on private lands. -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.Availabil ity of other regional recreation resources will affect demand in unpredictable ways as massive land status changes occur; -Schedule of selection and transfer of land title to the State of Alaska and the Native corporations,which will determine actual ownership at the time of implementation of project recreation fea- tures,and whether a suffi ci ent peri od (20 years)has passed to enable the native corporations to sell the land;and -Potential information developed in the recreation-use monitoring program described in Section 6.2 below. Implementation of the Susitna Hydroelectric Project Recreation Plan is divided into five phases: Phase 1,Watana Construct i on Phase,cons i sts of recreation features intended to mitigate the impacts of recreation opportunities lost due toconstructi on acti viti es and associated 1 and closures,to provide recreat ion opportuniti es for project construct i on workers,and to pro- vide the general public with some early-on recreation benefits derived from the public investment in Watana.Phase 1 projects are generally planned to be developed contemporaneously with the start of project construction. E-7-91 Phase 2,Watana Implementation Phase,consists of recreation features intended to mitigate the impacts of recreation lost due to the operation of Watana,to provide for the recreation use potential of the project,to accommodate project-induced recreation demand,to allow public access to project lands and waters,and to protect the environmental values of the project area.Phase 2 projects are intended to be developed within three years of the operational date of the Watana project,or when necessary agreements are reached ~/ith private landowners,for those projects on private land. Phase 3,Devil Canyon Construction Phase,consists of projects intended to mitigate the impacts of recreation opportunities lost due to Devil Canyon construction activities and to provide recreation opportunities for construction workers.Phase 3 projects are generally planned to be developed contemporaneously with the start of access construction to Devil Canyon,or when necessary qgreements are reached with pri vate landowners,for those projects on pri¥ate land.In addition,they will be designed to adjust to post-project recreation demand at Watana. Phase 4,Devil Canyon Implementation Phase,consists of recreation features intended to mitigate the impacts of recreation lost due to the operation of Devil Canyon,to provide for the recreation use potential of the project,to accommodate project-induced recreation demands,to allow public access to protect lands and waters,and to protect the environmental val ues of the project area.Phase 4 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 land. Phase 5,Post-Construct ion Monitori ng Phase,cons i sts of monitori ng recreation use.To begin when the first project recreation facilities are available in order to determine actual recreation use of the project features and to trigger adjustments in the recreation plan as required.The triggering mechanicsm is designed to initiate any necessary adjustments in the Phases 2,3 and 4 plans and at lO-year interval s thereafter throughout the 1i fe of the project 1i cense.

Therefore,Phase I of the Recreation Plan would be initiated at the time of starting construction.Phases 2,3 and 4 may be modified based on Phase 5 monitori ng.In general,the Al aska Power Authority I s com- mitment beyond Phase 1 is to acquire and develop the facilities listed in Phases 2,3 and 4 or their equi val ent as agreed to by the relevant agencies and landowners as spelled out in the FERC license.Modifica- tions to the Plan may be according to the provisions of Phase 5,Post Construct ion Monitori ng Phase,as detail ed below.Th is proposed Moni- toring Phase is written with the assumption that the ~aska Division of Parks will operate and maintain,with 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 agreements could be drafted with the BLM and "BLW'be substituted for "Division"accordingly.For project elements located on lands belonging 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 tied to acquisition of necessary agreements with the Native corporations.If,at a reasonable amount of time,the Authority and the Native corporations are not able to reach agreement on a particular element of the recreation plan,the Authority in cooperation with the Divison of Parks,will endeavor to find a site or sites suitable for the proposed recreation development on pub 1i c 1 and withi n the study area whi ch are appropri ate to the particular recreation opportunity matrix classification. Proposed Monitori"9 Phase The Division of Parks,with support of the Power Authority,will be responsible for maintaining facility use records and surveying use of Phase 1 recreation projects accordi ng to standards consi stent with Division practice and sufficient to determine their level of use.At the time Watana reaches operation,or 10 years after the completion of construction of Phase 1 recreation facilities,whichever is earlier, E-7-95 the Division and the Authority will jointly meet to evaluate recreation use patterns and to plan schedules and levels of subsequent development accordingly.The Phase 2 (Watana Implementation)Plan will be evalu- ated at this time and will be verified or modified as required con- sistent with the Recreation Opportunity Spectrum (ROS)classification appropriate for each proposed element.Construction of the Phsae 2 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 anQ anticipated demand gener- ated by the completion of the Watana project. The Phase 3 (Devil Canyon Construction)Recreation Plan will be simi- larly evaluated when construction of the Devil Canyon project begins. The elements recommended in this Plan will then be verified or modified as required,based on experience at Watana and anticipated demand,con- sistent with the appropriate Recreation Opportunity Spectrum c1assifi- cati on of each project e1 ement.Phase 3 wi 11 be constructed withi n three years of the joint determination of need by the parties. When Devil Canyon begins operation,or 1D years after the completion of construction of Phase 3,whichever is earlier,the Division and the Authority will jointly meet to evaluate the Phase 4 Plan (Devil Canyon Operation)and similarly verify or modify it as required. At the la-year anniversary of completion of construction of each phase, throughout the license period of the project,the Division and the Authority will jointly agree upon a plan for a major rehabilitation and/or construction relevant to the phase1s initial projects.It is anticipated that the Division of Parks and the Alaska Power Authority will enter into an agreement whereby the Division agrees to perform the survey,evaluation,design,constrlJction,operation,and maintenance of said recreation facilities on public lands with the costs to be borne by the Authority.It is also anticipated that agreements of similar intent will be entered into with the U.S.Bureau of Land Management and the Native corporati ons as appropr i ate. It is intended that the Authority will commit to the costs of the facilities specified in this Recreation Plan.Should any phase be modified by joint agreement of the Authority and Division under the terms of this proposed monitoring plan,budgeted monies may be trans- ferred from proposed element to element and from phase to phase.This is 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 1,2,3 and 4 does not exceed the currently anticipated total cost,as measured in constant 1982 dollars. E-7-96 - - .,... - .-. 7 -COSTS FOR CONSTRUCTION AND OPERATION OF THE PROPOSED FACILITIES 7.1 -General The foll owi ng cost estimates associ ated with the proposed recreation facilites and use are based upon 1982 prices for labor and materials and the assumption that the Alaska Divison of Parks will adminster the construction,operations',and maintenance of the project areas.No land costs are included in this exhibit.Additionally,all financial responsibil ities will be borne by the Al aska Power Authority.Costs of recreation facilities recommended for inclusion in the construction camps,construction vill ages,and permanent town are not i ncl uded in this exhibit.No costs are included for Phase 5 projects as they will become a part of the Recreation Plan only if monitoring determines that will be necessary. 7.2 -Construction A summary of estimated capital costs for each phase of the Recreation Pl an is presented in Table E.7.18.Breakdowns for these costs by project features are shown in Table E.7.19.The costs have been prepared based on State Division of Parks data and discussions with Alaska contractors. 7.3 -Operations and Maintenance It is intended that project recreation facilities will be operated and maintained by the State Division of Parks and/or the U.S.Bureau of Land Management,as appropriate.Table £.7.20 estimates additional equi pment necessary to operate the proposed faci 1 it i es.Tabl e £.7.21 summarizes estimated average annual costs for supplies,equipment and personnel to operate the facilities.The State Division of Parks recommends that no user fees be assessed • E-7-97 -----------------._------_.--,------------>-~---~ - - 8 -AGENCIES AND PERSONS CONSULTED The following list documents public agency,Native corporation,and University of Alaska consultations in the course of preparing this Recreat ion Pl an.Wr itten records of these conversat ions are avail ab 1e at offices of the Alaska Power Authority.

The Southcentral Region is geographically bounded by the Alaska Range to the north and west,the Wrangell Mountains to the east, and the Chugach Mountains and Gulf of Al aska 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 (1982 Alaska Almanac).Anchorage,with nearly half of Alaska's population and only 100 air miles from the project area, is located near the northeast end of Cook Inlet in the ~outhcen­ tral 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,wet lands,moi st and wet tundra as well as plateau/uplands and a number of active glacier bedded mountain valleys are other significant natural environments here. In addition,this diversity of landscapes is complemented with a wide variety of wildlife and flsheries. 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 characterlzed E-8-l --------------~---, ".,.. - ~ I E--S-2 'fo~q.(• i•i•i: E3I;lIe\I tl....-.....····.. REGIONAL MAP Plate 8.1 - ..... as a broad open landscape ot large brai ded and meanderi ng ri vers and streams.River valleys are primari Iy vegetated with spruce- hardwood forests gi vi ng way to tree less 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 Southcentral region,wi Idlife and fish- eries are as diverse as the landscape environments. Fairbanks,100 air miles north of the project area,is Alaska1s second largest urban center with around 30,000 residents.Due to a harsh winter climate and general inaccesSlbillty other than by air,the Interior Region is stifl predominantly a wilderness area. (b)Susitna River Basin The Susitna River Basin is located entirely in the Southcentral Region.The 39,000 square mi Ie area is bordered by the Alaska Range to the north,the Chulitna and Talkeetna Mountains to the west and south,and the northern Talkeetna plateau and Gu f kana uplands to the €ast. Although the basin is not considered as scenic in comparison to other natural resources in Al aska,the aesthetic resources are valued because of the basin's location between the two populatlon centers of Anchorage and Fairbanks. The basin has distinct and diverse combinations of landforms, waterforms,vegetation and wi Idl ife species.The deep V-shaped canyon of the Susitna River and tributary valleys,the Talkeetna Mountai ns and up I and plateau to the east are the domi nant topo- graphic forms.Elevations in the basin range from approximately 100 feet to over 6000 feet.Distinctive landforms include pano- ramic tundra highlands,active and post glacial valleys,and num- erous 1akes of both simp J e and comp Iex forms.The most we II known features in the basin are the vertical walled Devil and Vee Canyons on the Susitna River.Devil Canyon contains some of North America1s 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 the short autumn.Snow,ice and below zero temperatures create a harsh,threateni ng but sceni c wi nter Iandscape.Late Apr;I and May brings ice breakups on the rivers and the once snow-and ice- covered ground begins to come back to 1ife.The 1andscape turns green again as the cycle repeats. Other than the Susitna River itself,the silt-laden Maclaren and Ushetna rivers,the clear Tyone River,Portage,Devi I,Fog, Tsusena,Watana,Kosina,Jay and Butte creeks are the other major drainages in the Susitna Basin.Scenic waterfalls,occur on several of the creeks near their incised canyon confluences with the Susitna River.The most notab Ie occur on Devi I Creek . E-8-3 Spruce and mixed spruce-deciduous forests cover the bottom and slopes of river and tributary valleys below 2,500 f-eet elevation and west of the Oshetna River!Susitna confluence.Tundra and muskeg replace the mixed forests to the east and on the highlands with more drought resistant vegetation.Mountaln slopes are bare or lightlY covered. Wi ldlife species in the Susitna l:3asln lnclude Dafl sheep,moose, caribou,and grizzly and black bears.Avian species include bald and golden eagles,trumpeter swans,and numerous migratory water- fow I.Fi sheri es of the area inc Jude a II flVe AI askan sa Imon species,grayl ing,burbot,rainbow,and I ake trout.Because of the extremely turbulent waters of Devil Canyon,salmon are gener- ally only found below the canyon. Existing access into the interior ot"the basin is generally limited to hiking,float planes,aJI-terraln vehlcles (ATV),and watercraft.Uenall Hlghway passes through the northern portion of the basin linking the George Parks Highway to the west with the Richardson Hi ghway to the east.Severa I short road!trai Is tra- verse the tundra to mlnlng clalms and flshing!huntlng lodges. Primary human use of the basin is recreational hunting and fishing for subsistence use by local residents.Small mining operations are also found in the basin. In general,the Upper Susitna Basin is a relatively uninhabited diverse environment with regionally important aesthetic values. Any major project has the potential of creating significant aesthetic impacts to the basin and to the SouthcentraJ and Interior Regions.The lower Susitna Basin contains a significant portion of the State1s population and development while retaining extensive areas of both undeveloped and wilderness land.

(a)Landscape Character Type A unit of the 1andscape used as a frame of reference to classify the physical features of a given area.This is based to a large degree on physiographic sections as defined by Wahrhaftig (1965). - (b) (c) (d) Compatibil ity A relationship between the existing landscape and man-made fea- tures in which the proposed elements are designed in t·itness with the character of the existing landscape. Viewer Sensitivity An indicator of peoples'concern for aesthetic quality and their Ieve1 of expectation of aesthetic qual ify;necessari 1y somewhat subjective. Aesthetic Value A relative measure of overall importance of the visual landscape, including such components as distinctiveness,uniqueness,harmony and balance. E-8-7 -----,---_..:....._------_.------_.-._-.....--------------------- (e)Oistinctiveness A measure of the visual impression of an area;i.e.,a landscape where landforms,waterforms,rocks,vegetative or soi I patterns are of outstanding and memorable aesthetic quality. (0 Uniqueness A measure of the relative scarcity or commonality of the land- scape.Due to Alaska's vast and numerous high-quality land- scapes,uniqueness will have two levels of meaning for the pur- pose of this report: Landscapes and natural features mayor may not be unique on a statewide scale;and - Landscapes and natura I features mayor may not be un i que on - project area scale. (g)Harmony and Balance A measure of the degree to which all elements of the landscape torm a unified composition.This includes the lntegration level of man-made elements in a natural setting. (h)Absorption Capability A measure of a landscape's natural sensitivity of a landscape to alteration.Factors such as the potential for human experience, compatible site relationships,and aesthetic values are commonly considered. 2.3 -Proposed Project Facilities and Features (Step 2) The Susitna Hydroelectric Project has proposed a number ot faci Ilties and features which will potentially have aesthetic impacts upon the existing landscape.The tacilities and features are as follows: Appendix 8A shows the proposed layout of these facilities,and Appen- dix 88 includes photos of the sites for major items along with simula- tions of the faci lity itself.

Each feature was first rated in the impacts column lias proposed u - that is~as currently sited and designed uti lizing available informa- tion.If the rating is (C),no mitigation is necessary and the miti- gation column may remain blank.If the rating is (I)and no mitiga- tion is possible without significant design changes~the mitigation column remains blank.If mitigation is possible,the t"eature's adjusted rating is shown taking into consideration the mitigation measure~which may change the rating to (C)in some cases.In other cases~impacts may continue to be (I)~but may be lessened. E-8-45 If mitigation could be accomplished through redesign,the feature is assigned a new rating in the last column,listed in brackets on second line,to indicate the potential for decreasing aesthetlc impact of the feature through new design. To achieve the proposed level of mitigation,one or more of the fol- lowing four generic types of mitigation can be employed: (a)Addltional study required to consider alternative solutions, sites or corridor alignments with less impact on scenic quality; (b)The use of best development practices to minimize construction- re 1ated effects on the 1andscape and to gu i de post-construction cleanup and rehabilitation of disturbed areas; (c)The use of creati ve engi neeri ng design to assure that project features are well designed and are in themselves positive visual features;and (d)The use of form,line,color or textures appropriate to the land- scape character type. The type of mitigation suggested is indicated on the charts with letters;for example,a Ca rating would indicate that a feature could be made compatable with proper employment of type (a)mitigation. 4.3 -Project Impacts Summary (a)Watana Project Area -The Watana Dam has been rated incompatable (no mitigation possible)to the Susitna River Landscape Character Type (LCT). The area is incapable of absorbing such a massive element which contrasts in texture and color.The dam form itself is in character to the river banks,however,its orientation in the val ley causes it to be visually dissimilar. -The Main Spillway is also rated incompatable (I).The proposed lOO-foot deep cuts wi II leave large scars on the river valley side and the concrete channel is in sharp contrast to the dark colors of the Susitna River LCT.With proper mitigation,the spi llway coul d become compatab leo -The emergency spillway which is rated I will have impacts slmi- Iar to the malO SPl I Jway.In addition,the channel wi 11 have a significant impact on dam visitors who will view the its entire length as they cross the spi Ilway brldge.Mitigation is pos- sible which would improve the situation. E-8-46 - - - ..... -Watana's Powerhouse Access Road also in the Susitna River LCT will cause significant impacts to the area of the dam as viewed by vi s itors and workers.The road wi 11 requi re 1arge steep cuts in the val ley wall WhlCh wi II be difficult to recover with native vegetation.The road is rated I but could become a C with proper mitlgation. -Watana Reservoir wi II essentially e Ilminate the Susitna River and Ri ver Canyon LCTs in the areas of impoundment and are therefore rated Incompatible in this setting (no mitigation. possible).Although reservoirs are not necessarily a negative element aesthetically,the large drawdown areas of Watana wi II be a negat i ve impact to vi s itors and workers at the dam area as well as to recreationists on the reservoir itself. -The Watana switchyard wi II be located in the Wet Upland Tundra LCT and has been rated as 1.Th is is because the form and tex- ture of switchyard equipment is in sharp contrast to the land- scape,and the area is not capable of absorbing the feature. Mitigation could improve these impacts but not eliminate them. -The Watana Borrow Areas may potentially be a very significant impact on the areas around Watana if their ultimate form is in contrast to existing character,and natural vegetation does not hide the scar.The Borrow areas are rated I,with mitigation a C is possible. -The tailrace tunnel access road will have simi lar impacts as the powerhouse access road on the south side of the dam and it h as been rated I. The Wat ana Ai rstri pis rated compatab Ie.It will not be in contrast to the wet upland tundra (LCT)and the area is capable of absorbing this visual change . .-Watana Permanent Town is rated I but could receive a C if redesign studies were done.The town is very disruptive visu- ally. (b)Devil Canyon Dam Area -The Devi 1 Canyon Dam area wi 11 be a very strong element in the Devil Canyon LCT.The dramatic size and form wi [I be a posi- tive element and is in character to the setting. -Devil Canyon Saddle Dam is not a visually existing element, therefore,the contrast of form,co lor and texture it i ntro- duces into the sensitive Devil Canyon LCT will be incompatable. No mitigation is possible to make it compatable although some improvements are possible. E-8-47 -Devil Canyon spillway is incompatable to the area.The form of its deep cut and the color of the concrete and denuded slopes wi 11 be a significant visual impact to visitors at the Dam and Visitors Center as well as to workers in the area. -The Devi I Canyon Emergency Spi Ilway has very simi 1ar impacts as the main spillway and is also rated I.This spillway,however, is not as prominent from the main vantage points of the Canyon bridge,Dam and Visitors Center. -Devil Canyon Reservoir,like Watana,will eliminate the exist- ing LCT.1t has been rated 1.fhe visual impacts of this reservoir will not be as severe as Watana because a lower fluc- tuation differential and steeper banks wil I result 1n less area during drawdown becoming exposed.However,the areas will be visible during the times at heaviest visitation to the dam and reservoir.No mitigation is possible. -Devil Canyon Powerhouse Tunnel Access road has been rated I as a resu It of the maj or cut s and areas at"veget at 1on removal required to construct the road down the steep slopes. -The Devi 1 Canyon Switchyard wi 11 be in sharp contrast to the existing 1andscape character as 1S the switchyard at Watana. Ihe yard is rated I because the setting cannot absorb this feature,however,mitigation is possible to lessen the impacts. -Devil Canyon Transmission Lines will be visible from the access road.the bri dge and the dam.They have been rated I 1 n the [Jevil Canyon LCT because they are difficult to hi de here and the points of viewing are important within the Mid-Susitna River Val ley LCT.The lines have been given a C rating because they will be more easily hidden by scattered trees and proper alignment in the topography. (c)Access Roads and Rail -The Watana Access Road runs through the wet upland tundra LCT which has a high composlte rat1ng and the Chulitna Mountains LCT which is also rated high.In both of these areas,the road has been rated incompatable because of the LCTs low capab111ty to absorb visual change such as the significant cuts and fills required for construction as the road is proposed.A Crating is possible within these LCT settings with the proper mitiga- tion and careful road design. -The Borrow Areas for Watana Road are located 1 n the same LC I S as the road and have been rated as i ncompatable.These areas are very sensitive to disruption and excavation activities wi II be very difficult to hide. E-8-48 - - (d) (e) The Watana to Gevil Canyon Access Road traverses three distinct LCTs:Wet Upland Tundra~Chulitna Moist Tundra Uplands and Devil Canyon.The road has been rated I in all of these set- tings for the same reasons as the Watana road.However,"in the first two LCTs the road could become compatable if carefully mit i gated because these areas can more easi ly absorb the change and their character is more compatable with road forms.Wlthin the Devi I Canyon LCT,however,there are no methods to make the road compatable due to the constraints of topography and the areas high visual sensitivity. Borrow Areas for the Devil Canyon Access Road occur in the same LCTs as the road and are incompatab Ie for the same reasons. -The high level bridge below Devil Canyon Dam has also been rated as incompatable as it is currently proposed.The bridge Wl II ofter visitors an opportunity to view the dam and canyon. This bridge when viewed from other points will be a very prominent element in the Devil Canyon LeT,and unlike the dam has not been engineered to be a visually exciting and positive visual element in the area. -The rai Iroad spur from Go Id Creek to Devi I Canyon runs through the Mid-Susitna River Valley and has been rated incompatable to this LeT as a result ot the extensive disruption and scars Whl ch wi 11 result from construction. Construction Worker Accommodations The Watana Vi 11 age and Camp are located in the Wet Upl and Tun- dra LCT and have been rated as i ncompatab Ie because ot the large areas WhlCh wlil be disturbed,and the introduction of 1 arge numbers of structures into an area whi ch cannot absorb the change.Proper des i gn wi II mit i gate thl s impact but cannot make the towns compatable to the setting because of their great contrast to the existing landscape setting. -The Devil Canyon Camp and Village are located within the mid- Susitna River Valley LCT and are rated incompatable for the same reasons as the Watana Camps.However,mitigations will need to be modified to respond to the unique character of this settlng. Transmission Lines -Temporary 138 kV transmission line.This line from Watana to the Denali Highway is rated incompatable to its setting.The Chulitna Mountains and Wet Upland Tundra cannot absorb this feature,however,with proper siting~the views of lt can be limited. E-8-49 -The two 345 kV transmission lines from Watana to Gold Creek pass through fi ve distri ct LCTs.Within the Devi 1 Canyon and SusHna River environments,lt has been rated as incompatable because of its high visibility and this areas inability to screen the lines from view.Within the mid-Susitna River Valley and the Talkeetna Uplands,the lines are rated compat- able because they are not in conflict and the settlngs are cap- able ot absorblng the drainage.The Chulitna Moist Upland Tundra could absorb the lines if proper mitigation is followed, however,at present the lines are lncompatable. -The Gold"Creek Switchyard is rated compatable to the mid- Susitna River Valley because the area is capable of absorbing the feature as designed. -The Anchorage to Willow Transmission stub line passes through the Anchorage and Susitna River lowl ands and have been rated compatable because these settings are capable of absorbing the new features without causing degradation of the eXlstlng visual character. -Healy to Fairbanks Transmission stub line is rated as compat- able in the Nenana River lowlands for the same reasons discuss- ed above.Within the Nenana Uplands and the Tanana Ridge LCTs, the line has been rated I because of its high visibility and the area1s low absorptlon capabi lity. -Recreation Features have been all rated cornpatable to their LCT settings because they do not,for the most part,constltute a slgnlflcant visual modification to the environment.The excep- tion to this is the visitors center,one on the south side of Devil Canyon Dam and other on the north side of Watana Dam. With proper design,these will also be visually compatable to thelr settings. -The Construction Practices have also been evaluated for their aesthetic impacts which will last after activity has ceased. Th 1 s inc I udes rock cru sh 1 ng Whl ch cou I d potent 1 a I I Y create large amounts of blowing dust and visual degradation.Vegeta- tion clearing for construction activity areas,and spoil sites will leave lasting scars on the landscape.All of these are considered for the proposed aesthetic evaluation to be lnher- ently lncompatable to their environments and careful mitiga- tions will be needed.

(b)The use of best development practices to minimize construction- re 1ated effects on the 1andscape and to gu i de post-construct i on cleanup and rehabilitation of disturbed areas. (c)The use of creative engineering design to assure that project features are weJ J designed and are,in themselves,positive vis- ual features. (d)The use of form,line,color or textures approprlate to the land- scape character type in facility design. Appendix 80 shows illustration of these mitigations for the major project facilities. E-8-97 AESTHETIC RESOURCES PROPOSED MITIGATION MEASURES - STEP! PROJECT FEATURE WATANA PROJECT AREA WATANA DAM MAIN SPILLWAY EMERGENCY SPILLWAY WATANA RESERVOIR POWERHOUSE ACCESS ROAD MlTIGAT10N MEASURES •The scale of Watana Dam will be impressive but its size and form are incompatible with the highly rated character type. •No mitigation possible. •As with the dam,the scale is large and it will cause significant aesthet ic impacts in relation to the character type. •While no mitigat ion measures will render it compatib Ie as engineered, further study may result in alternate solutions which are compatible or have less adverse impacts on the landscape. •Tunnel (underground spillway)versus open channel solution would be compatible if feasible and properly designed. •Terrace steep side slope cuts to approximate character ist ic slope gradients and surface textures. •The scale and form of this feature as engineered will not be compatible in the given character types and no mitigation will make it c ompatib Ie • •To lessen the visual impact,study should be conducted to determine if it is possible and feasible to deposit spoil material oveJ;'the rock floor of the spillway and revegetate with tundra species. •Terrace steep side slope cuts to soften form and approximate characteristic slope gradients. • A tunneled spillway would be compatibe if feasible and properly designed. •Consider a curving channel form to reduce the visual impacts at the point at which the road crosses the spillway. Revegetate the Fuse plug dam with tundra species. •Impressive scale,but expected large scale erosion and extensive drawdown make the reservoir incompatible in all character type in the impoundment area.No mitigation is possible to reach compatibility or lessen adverse visual impacts. •No mitigation is possible for the construction of a road of this nature down the steep slopes of the river valley. •An elevator structure (alternative solution)down to the powerhouse with connecting tunnel would eliminate need for surface access road and its impacts.Consider accessing both powerhouse and tailrace tunnel by same or multiple elevators. •Consider road tunnel rather than surface road (alternat ive solution).

BORROW AREAS TAILRACE TUNNEL ACCESS ROAD TEMPORARY AIRSTRIP •An extensive area of the Susitna River (north side)below the Watana Dam site is proposed for potential material extraction.Significant large scale incompatible changes are probable.Careful planning, design and construction can lessen impacts.(Filling of Devil Canyon reservoir will also flood these areas.) •Engineered design of borrow areas in and along the river I'i1 ich positively respond to the form,line and texture of the existing area Idll help lessen the adverse visual appearance. •Further study by an interdisciplinary team may result in alternate site selections and/or extraction techniques which will be compatible with the character type(s). The large proposed borrow area on the north high terrace area north of the dam site will not be compatible because of the straicf1t edge/form indicated in proposed plans. •Irregular edges and abrupt rock forms would make the form compatible to the landscape.This edge is especially important because it will become a part of the reservoir edge when the area is inundated. •The rock quarry located between Watana Dam and Fog Lake will have significant visual impact.Forest·clearings should be lineal'with irregular edges to approximate existing openings.Clearings should not be symmetrical in form. •See mitigation measures for Powerhouse Access Road. If surface road (rather than elevator or tunnel)is required,consider accessing both powerhouse and tailrace tunnel with the use of one road. •Proper siting and careful construction practices to contain clearing and grading will help minimize adverse impacts to the landsc ape.

STEP I PROJECT F=EATURE PERMANENT TOWN TWO 345-kV TRANSMISSION LINES (WATANA TO GOLD CREEK SWI TCHYARD) MITiGATION MEASURES •The proposed townsite and layout will be incompatible with the given character type.No mitigation possible to make it compatible. •An interdisciplinary team should be utilized to best site,arrange and design the town layout and individual features.This approach 'Hill help create a town which is aesthetically attractive to viewers and residents. •Further study by an interdisciplinary team should-result in the select ion of a townsite which will be more compat ib Ie with the landscape.Harmony and balance between the character type and town is possible with proper design and siting.Positive visual interest could result. •Although the proposed route was selected for its high ability to cause minimal adverse aesthetic and environmental impacts,the large scale of the feature in relation with the highly aesthetic landscapes through which it passes results primarily in an incompatible situa- tion.Mitigation measures are possible in many conditions to assure minimal aesthetic impacts,and in some cases make compatible re let ionships. •The selection of CORTEN-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 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 bec.ause of their high visibility. •AlijJnment through valley centers should be avoided as these areas would become major focal points as would ridge tops. •utilizing helicopter construction methods in inaccessib Ie and env iron- mentally sensitive areas ,..ill help reduce adverse aesthetic impacts. •Winter construction in open tundra areas will eliminate the potential visual impacts caused by ~he construction of access roads/trails dur ing ather 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 mitijJation measures to make it compat ible. However,creative engineering design and proper sitinjJ of towers will lessen adverse impacts.The maximum 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 walls. Educate project workers and especially equipment operators in construc- tion methods which result in minimal environmental impacts which directly relate to aesthetic impacts.Identify environmentally sensitive areas.Use visual aids to stimulate interest. •River,stream,canyon and road crossings should be made at 90-deg angles.

WAf ANA ACCESS ROAD •With an interdisciplinary alignment planning and design approach,it is possible to construct a road compatible with the landscapes through l'ttIich it passes. • A maximum design speed of 40 mi/h will result in a road which better fits the topography and requires less cut and fill work.These measures will lessen visual as well as environmental impacts. •Wooden trestle type bridges rather than concrete bridges would be more aesthetically attractive. •In areas where the road must traverse dam,up steep slopes.,a concrete-cantilevered road structure set on pilings would reduce or eliminate extensive cut and fill slopes.This would not only result in significantly less aesthetic impacts but also reduce environmental impacts. •Clearing in forested areas should be kept toa minimum.Irregular feathering of edges should be done to approximate existing natural edges. •Road dust control should be developed.Water application is recommended. 1 1 L L L L I- l •With sensitive siting,extraction and rehabilitation methods,borrow sites are capable of being compatible in most character types. •Extraction of material in existing rock dominated uplands would be appropriate as long as access to these areas does not require exten- sive roads/trails.Consider winter extraction from these areas. •Contour ing the borrow areas to appl'oximate surrounding slope gradients and avoiding man-made,unnatural appearing edges and/o:L'forms during the extraction process will assure minimal negative visual impacts. •Organic topsoil should be distr ibuted over extract ion areas and then scarified and fertilized.The site should then be left alone for invasion of natural tundra species. •Where possible,borrow areas should be filled to natural grades with spoil material.Again,organic topsoil should be distr ibuted and the previous procedure followed.

As this new facil ity wi 11 carry 'power generated by the Susitna Project over a system expanded to serve the project as shown in Figure E.8.5,it is briefly discussed herein. (b)Project Description The Intertie will extend from Willow and Healy,where it will ultimate ly connect with Sus itna Hydroe 1ectri c Project features referred to as "Stubs".Figure E.8.S illustrates the inertie as it is planned to be constructed in 1983 along with subsequent additions for the Susitna Project 1ncludng the stubs and dam interconnections.The intertie will be a 170-mile long facility constructed basically of guyed steel "X"poles.Angle structures will be three separate vertical pole structures with single-pole hillside structures.All towers will be made of self-rusting (Corten type)steel and conductors wi 11 be nonspecul ar .All facilities and structures will be identical to those descr1bed 1n the V1 sua I ana lyS1 s of the Sus itna Hydroe 1ectri c Project transmission lines in previous sections of this report.At 1nitial construction,the line wi II be energlZed at 138 kV. When the Watana Project comes on line in 1993,a second parallel 1 ine wi 11 be added to the Intertie,the 11stubs"wi 11 be con- structed,the lines will be energized to 345 kV,and a switchyard built near Gold Creek to connect with Watana power.in 2UU2, when Dev11's Canyon comes on line,a third parallel line will be bui lt on the Gold Creek to Wi 11 ow port ion of the 1ine,and the Wi I low to Anchorage stub W1 I I 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. (c)Landscape Character Types Commonwealth identified six landscape character types based on the Alaska Department of Natural Resources 1981 stUdy,Scenic Resources along the Parks Highway.They are; -Susitna River Lowlands -Cook Inlet to the southern entrance of Denali State Park -Curry Ridge -Denali State Park to Curry Ridge E-8-107 -Chulitna River -Curry Ridge to East Chulltna River -Broad Pass -East Chulitna River to Denall Hlghway -Alaska Range -Denali Highway to first Nenana River Crossing of Parks Highway at southern boundary of Denali National Park -Nenana Gorge -Nenana River Crossing to Healy. However,inspect i on of the route shows th at the 1andsc ape un it types which will actually be traversed are as follows: -Susitna River Lowlands -Talkeetna Mountains -Chulitna River -Broad Pass -Alaska Range -Yanert River Valley -Nenana Uplands Therefore,these were units analyzed for the purposes of this .report. These landscape unit types and the approximate point of inclina- tion (P.I.)of the transmission line are as follows. (i)Susitna River LOWlands Wi llow SUbstation to P.I.14 at the crossing of the Talkeetna River. Extending south from near the town of Talkeetna to its mouth on Cook Inlet,the broad and heavily braided Susitna River flows through a topographically flat,sometimes rol ling landscape.Muskeg bogs and hundreds of relatively small lakes and ponds are scattered over the land. Sparse black spruce bogs are found on the poorly drai ned areas while moderate to dense spruce-hardwood forests exist in areas with higher relief. Paralleling the Susitna from near the towns ot Wlilow and north to Talkeetna,the Parks Highway is the shortest and heavi est used access route between Anchorage and Fai r- banks.A number of small communities and recreation sites occur along or near the road.In addition,the Alaska Railroad alsoparal lels the Susitna River and Parks High- way here. Many of the larger and more scenic lake areas are popular summer and permanent home sites for hundreds of Southcen- tral Alaskans.Some are accessed by road whi Ie others are only reached by float plane. E-8-l08 """ '""", - .... I"""""'" Spacially open areas otter vlews to the Talkeetna and Chugach Mountains~and the Alaska Range.Mount McKinley 1S to the north and the flat topped Mount Susitna is near- by to the southwest. (ii)Talkeetna Mountains (P.I.14 to P.I.41 above the crosswg ot the Susitna River.) While the Uepartment ot Natural Resources study classifies this area as the Talkeetna Mountains~for the purposes of this transmission line study~that designation has been subdivided into three sUbtypes -Talkeetna Mounta1ns to the south and west of the trans- mission corridor -Talkeetna Lowlands -Talkeetna Uplands. The proposed ali gnment passes through these 1atter two character types which are described below. (iii)Lowlands Portion After steeply rising several thousand feet from the Susitna River Valley,the landscape in the lower Talkeetnas becomes a rolling terraced/plateau.With a few knobs rising above 4,000 feet the average elevation is around 3~OOO feet. The dominant tundra enV1ronment here is very wet and con- tains hundreds at"small lakes and muskeg bogs.Spruce trees are scattered throughout the area,but usually found at lower elevations within the drainages.Gold, Cheechako~Chu 1itna and Di sappoi ntment Creeks are among the more scenic drainages. The f I at and roll i ng character ot these up I ands affords panoramic views to the Al aska Range,Chul itna.and Ta"lkeetna Mountains.Views of the surrounding river valleys from high points and terrace edges are also very good. Access into the area is predominantly by float plane~ snowmobile and use of a few existing mining and/or settle- ment trails. -~ (iv)Uplands Portion Approaching its confluence with the Susitna River,the braided Talkeetna River and western tributaries pass through a terraced and hi Ily landscape.Th1S area is £-8-109 mostly covered with a dense spruce-hardwood forest. Muskeg bogs are common but not as expan si ve as in the Susitna Lowlands. There are a number of lakes in the area used both for rec- reation,and home or cabln sHes.Approximately four mi I es long,the narrow Larson Lake is the I argest of these. The dense forest cover restricts V1Slon,but scenic views of the Alaska Range,the Talkeetna and Susitna Rivers,and the immediate Talkeetna Mountains proper are posslble from occasional elevated spots and widened river channels. Access into the area is primarily by foot,float plane, boat and a limited number of jeep ATV or horse trails. (v)Chulitna River P.I.41 to P.I.48 on the Chulitna River. DlViding the Alaska Range and Chulitna Mountains,this flat to rolling river valley is predominately an open tundra-covered landscape.Sparse to moderately dense spruce-hardwood forested areas occur along the meandering Chulitna River and its tributaries. The dominant Alaska Range rises gently from the valley in comparison to the steep rise of the Chulitna Mountains. Hurricane Creek and Gulch form a dramatic descent from the Chulitnas.Spectacular mountain,glacier and val ley views are offered in open areas and vantage points. The Alaska Railroad and George Parks Highway parallel the river 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 valley.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. (Vi)Broad Pass P.I.48 to P.I.65 north of the Nenana River. Over 10 mi les wide near the town of Broad Pass and narrow- ing to 4 mi les wide near Cantwell,this area known as I:3road Pass,separates the Al aska Range and the northwest Chulitna Mountains.Ihis open,t-Iat to rolling landscape is very scenlC wlth its long and linear lakes,variety of tundra and spruce cover patterns,and mountain views. E-8-11 0 JIlIIl'l!1lL - - The Parks Hi ghway goes through the northern si de of the pass near the Denali Natural Monument boundary.The Alaska lJepartment of Natura I Resources recommended in thel r 1981 Scenic Resources alon the Parks Hi hway report that the road between Broad Pass town and Windy be considered for scenic designation.The Alaska Rai Iroad passes through the Summit Lake area and parallels the highway.Cantwell is the west junction of the Denal i Highway with the Parks Highway. (vii)Alaska Range P.I.65 to midway between P.I.70 and P.I.71 on the southern edge of the Yanert River Valley,and P.l./4 to P.I.83 near Moody Creek southeast of Healy. - (viii) Featuring North Amerlca 's highest mountain,the U-shaped Alaska Range extends nearly 600 miles from an area west of the Cook Inlet to the Alaska-Canada border.rhlS well known mountain range with its hundreds ot glaciers is the dividing feature of the Interior and Southcentral region of Alaska.Elevations range from approximately 2,000 feet in adjacent valley to over 20,000 feet at Mount McKinley. Nenana Uplands P.I.83 to P.I.~o Healy Suostatlon Site. Extending north from the Nenana I<lVer Gorge to the flat Nenana Lowlands,the river becomes progressively more braided as it flows through a rolling and terraced valley. Sparse spruce-hardwood stands are found near the ri ver bottom whi Ie moderate Iy dense forests cover much of the upper terraces.Rock outcrops are common along the edges of the rising terraces. Views are directed to the east where the terraces rise up to the higher reliefed Alaska Range foothills.While the Parks Highway and Alaska Rai lroad do not slgnificantly degrade the visual quality ot the landscape,existing transmission lines do present a negative aesthetic impact. 1""-'" (i x)Yanert River Vall ey P.I.71 to P.I.74 A 35-mi I es swath through t he AI aska R.ange east from the Nenana River,the Yanert River Valley ranges from 2 miles in width at the Yanert Glacier to over 5 miles at the con- fluence with the Nenana.The Yanert River is heavi ly braided for most of its length before turning into a E-8-l11 broad fixed channel river for the last 5 miles.The valley is tundra dominated with scattered stands ot spruce adj acent to the rlVer bottom.The Alaska 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. (d)Description of the Preferred Route The preferred transmission line route extends 170.1 miles from the proposed W-j llow substation slte to the proposed Healy substa- tion and can be generally described as follows. Willow Substation is proposed to be located near Willow Creek about 1-1/2 miles east of the Parks Highway.Thence the align- ment follows the Matanuska Electric Assoclatlon rlght-of-way approximately 19 miles north.It continues in the Susitna Low- lands until Chunilna Creek,northeast of Talkeetna,whence it proceeds east and up into the Talkeetna Mountains,before drop- ping back to the Susitna River near Gold Creek.The alignment then proceeds due north east of Chul itna Butte and joins the Chulitna River Valley.It generally parallels the river valley, Parks Highway,Alaska Rai Jroad corrldor,through Broad Pass,and north up the Nenana River Valley to the Yanert Fork.The line then jogs east of Sugar Loaf Mountai n,northwest down Moody Creek,and continues in a northwesterly direction into Healy. (e)Alternatives Many minor route adjustments and subalternatives were considered by Commonwealth.In addition,three major alternatives were con- sidered. -An alignment parallellng the Parks Highway from south of Sunshine to Chulitna Pass. -An alignment west of the highway from Broad Pass to the first Nenana River crossing of the hlghway. -An al ignment along the Nenana Gorge rather than east of Sugar Loaf Mountain. In addition,alternative pole configurations,voltage levels, selective undergrounding,and alternative systems to the Intertie were considered and rejected. (f)Impacts A cursory examination of visual impacts based on aerial and limited ground inspection of the preferred and alternatlve allgn- ments,study of U.S.G.S.topographic maps,and analysis of the Commonwealth report is as follows. E-8-112 -- -, - - ..... - (1)Susitna River Lowlands -The line will generally be dis- .tant enough from the Parks Highway and screened by vegeta- tion in this low landscape unit type that it will be largely unseen by most viewers on the ground. (li)Talkeetna Mountains -rhe Ilne W1JI be hlghly vislble as lt crosses the Talkeetna River,an important recreational resource.Particul arly when the Intertie is expanded to two and then three fines,visual impacts will be signifi- cant at this pOlnt.The route over the mountains north of the river wi 11 not be generally visible unti 1 it again nears the Susitna River,when it will be in full view from Curry Ridge in Denali State Park. (iii)Alaska Range -The line(s)will be highly visible along the Indian Rlver,at two crosslngs of the Alaska f{ai Iroad, and from portions ot the planned remote parcel land dis- posal areas between Gold Creek and Hurricane.Further north,between Cantwell and the Yanert Fork,the lines wil I pass crose to the Parks Highway in areas rated by DNR as having 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. (iv)Chulitna River -From about Honolulu Creek to the east fork of the Chu I itna,Ihe Department of Natural Resources has rated this portion of the Parks highway one of moder- ately high scenic resources and moderate to low absorption capability.Whl Ie predominant Vlews are to the west,the transmission line will be visible to the east. (v)Broad Pass -DNR recommends that this area be officially designated a scenic highway.Because of the landscape's low to moderate absorpt i on capabi I ity,they recommend no development within 1 mi Ie of the Parks Highway.Ihe a I ignment ranges from a few hundred feet to approximately 2 mi I es from the highway as it passes through thi s unit. Visual impacts wi II be high.The crossing of the Denali Highway,currently under stUdy by BLM,for scenic highway designation,wi 11 also be in full view. (vi)Yanert River Valley -Crossing this valley,the alignment is approximately 2 miles east of the highway and wil I not have major impacts. (vii)Nenana Uplands -The location ot the Healy substation near the Alaska Rail- road and Nenana Railroad will be highly visible and has negative visual impacts.

Since the 1940's,the Susitna River has been considered for hydropower development and several preliminary plans for such development have been prepared.Proposals prior to 1980,which included one to four reservoirs did not proceed beyond the pre-feasibility analysis stage. The present project focuses on a two-dam development:one at Devil Canyon and one near Tsusena Creek (Watanadam site).These two struc- tures would create elongated reservoirs one-half to one mile,except for a portion of the Watana Reservoir,which would be five miles wide. Land use activity and development withi n 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, Environmenta 1 Studies Subtask 7.07:Land Use Ana lysi s,Phase I Report, April 1982. 1.1 -Purpose and Approach (a)Objectives The land use analysis involved an evaluation of the changes in land use likely to be caused by the project and provides the basis for summarizing the overall land use impacts of the project.The analysis was designed to provide baseline data and an impact assessment to: -Describe past,present,and future land use; Identify potential changes in land use resulting from the development of the project; -Describe past,present,and potential future land status; E-9-l -Identify potential changes in land status resulting from the project development; -Evaluate the project's impacts on land use and land status;and -Identify mitigative measures to minimize impacts. The scope of work is temporally 1imited from 1940 to present and geographi ca lly by study area boundari es establ i shed duri ng the first year of the analysis (Chapter 1 of Exhibit E). The 1and use ana lys is descr i bes and eva 1uates 1 and development, dispersed use acti vit i es and 1 and management.It does not gene- rate data concerning the use of the land by various animal spe- cies,nor does it include other detailed descriptions of the physical environment.Information on these subjects is provided in Chapter 3 and 6 of Exhibit E. (b)General Discussion of Land Use Evaluation Procedures Present land use development in the Susitna Project area is subtle and wi dely di spersed.Aeri al photographs and topographi c maps were used to locate cultural features such as trails,structures, and other indications of past and present land use.An oral history technique was employed to aid in identifying present dis- persed land use activities.Present patterns of human land use withi n the project area and the forces that created different types of use were evaluated.Aerial and ground truthing 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)resource management. Di spersed and i sol ated non-site specifi c activity i ncl udes pat- terns 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 includes that involving some form of long-term development or other commitment of resources.These include residences,commer- cial properties (primarily recreational),mining,agriculture,and transportat ion. E-9-2 - Resource management involves consideration of present and proposed land management plans developed by agencies with existing or pend- ing jurisdiction.Examples are fish and wildlife management,dis- persed recreation management,and off-road vehicle management pre- pared by federal,state,or local agencies,or Native corpora- tions.Native claims,land values,and status of land ownership were also considered during land use analysis. 1.2 -Summary of Current Land Status Issues in the Project Area The land status in the project area is complex.Most of the land in the Susitna drai nage area is owned by the BLM.There are two state land disposal areas west of the project,and Native conveyed land in the project area.The Alaska Statehood Act of 1958 and ANCSA of 1971 withdrew the land in the project vicinity from development and acquisition.Most of the lands in the dam and impoundment vicinity have been withdrawn for Native and State selection. The Cook Inlet Regional Corporation and associated Village corporations have selected lands along the river.Some lands along the river have been conveyed from the BLM to these Native groups.Part of these lands however,have been filed as valuable lands to the United States for water-power sites.Therefore,the 1ands conveyed under ANCSA are subject 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 cl aim to compen- sation shall accrue from the occupation of the land by the owners. Payment of damages to land use improvements will be made to the owner in the case the site is selected for water-power development.Contro- versy exists about the interpretation of the rights of the landowner and of the water-power licensee under Section 24 of the Federal Power Act.. The State also selected lands along the Susitna River.State selection was suspended until the Native groups completed their selection.Upon conveyence of Native selections,the State w"ill assume the remaining selected lands for its selection allotment. 1.3 -Summary of Land Use in the Project Area (a)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 basi c activity carri ed on by man in that area. E-9-3 Historical artifacts which were identified to describe past acti- vities included manmade objects used in the project area between 1940 and 1980.Information relating general location and use to each existing artifact was reported by oral history interviewees directly associated with the project area,current-day users of the project area,and researchers working at specific project area locations.All reported artifacts were located and verified in the field and were used to identify previous land use in the pro- ject area.Historical artifacts found within the project area were 1)structures,which include cabins,cabin foundations,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- ing,trapping,food or equipment storage,research,recreating (such as skiing,swimming,and photography),and mining.Basic categories covering the frequency in which the existing structures were used consist of:1)no use;2)seasonal use -past;3) seasonal use -past and present;4)year-round use -past;5) year-round use -past and present;and 6)no use i nformat ion. 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 transportation within the area,and for access to the project area.Airstrips on gravel bars or fl at 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 air- strips,lakes (on which ski or float planes landed),fishing streams,or another structure.. A review of the historical artifacts reveals that they were sparsely distributed throughout the project area,and used on a seasonal basis.The majority of the artifacts were used for hunt- ing,fishing,trapping,boating,mining,or other general recrea- t i on purposes,such as cross-country sk i i ng or photography.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 707,Land Use Analysis,Phase I Report,Apr il 1982. (b)Existing Land Use As in the past,access continues to determine the types and levels of land use in the upper Susitna River basin. E-9-4 ~: ,4'0! (i)Land Use Act ivi ty (i i ) 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. Land Use Development Developments typica11y include sma11 clusters of cabins. There are approximately 109 structures within 30 kilometers (18 miles)of the Susitna River between Gold Creek and the Tyone River.These include four lodges involving 21 struc- tures.Concentrations of residences,cabins,or other structures are near Otter Lakes,Portage Creek,High Lake, Gold Creek,Chunilna Creek,Stephan Lake,Clarence Lake, and Big 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 mining area (19 cabins and related buildings).Chunilna Creek and Gold Creek also have some mining development.Three commercial lodge operations are 1Qcated 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- prehensive land use plans in effect for the project area.The State 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, especi a 11y ina wil derness area.It wi 11 create developed areas; increase access and activity patterns,effect transfer of land owner- ship and redirect land management. (a)Land Status The proposed project will be located in areas involving signifi- cant Native and state selected and interim conveyed lands. Implementation of the project will require purchasing or obtaining rights-of-way to project lands.Increased land management may be required to respond to increased use. E-9-5 (b)Land Use Activity The project will result in significant increases in activity pat- terns in the upper Susitna basin.involving hunting.fishing. camping.boating.and dispersed recreation.Persons who currently use the Upper Susitna Basin will adjust to the increased use or move to other areas. (c)Land Use Development The project wi 11 resul tin 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,Deadman Falls and considerable surface disturbance 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 2.5 kilometers (1.5 miles) 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 absence of any project.Making a definitive forecast of future land 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 management 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; -minimal land use activity;due to the remoteness of the area. The results of discussions with the Bureau of Land Management (BLM).Al aska Department of Natural Resources (DNR).Matanuska- Susitna Borough (Mat-Su Borough)and the Cook Inlet Region.Inc. (CIRI)are meaningful within the context of general £-9-6 resource management in present-day Alaska.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 management is tenuous because of uncertain outcomes of the Alaska National Interest Lands Conservation Act (ANILCA)and the Susitna Hydroelectric Project. The project area has not been exploited in the past because of limited economically feasiblility.Discussions with land owners/ managers and consideration of present market conditions indicate that without the project,1 ittl e change is 1 ikely to occur in existing land use patterns,regardless of changing land ownership. Even if the State of Alaska or the Cook Inlet Region,Inc.and village corporations sell remote parcels surrounding the acces- sible lakes,it is unlikely that there will be any significant change until access into the area is improved. Although Native land owners have expressed their intentions to exploit the mineral potential of lands south of the project area, no specific plans have been identified.Access appears to be the key to such development. E-9-7 -I l 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 illustra- ted in Figure E.9.1.The following definitions of land classifications pertain to the lands within the vicinity of the Susitna project. Figures E.9.2 and E.9.3 illustrate the land status in the impoundment area. Federal:Lands under jurisdiction of the Bureau of Land Management (BLM),the Al aska Railroad,the National Park Service,or the U.S. Department of ArJTtY or Air Force. Unpatented Mining Claims:Mining claims operated by an individual(s) on federal lands.The federal government has the claim patent.Patent mining claims are privately owned. State Selected:The state receives land from the federal government in a three-step process.The state fi rst appl i es to the BLM for 1and that is classified as State Selections Applications or Federal State Selected. State Selections Tentatively Approved or State LA.:State selected lands approved by the federal government for transference to the state. State Selections Patented:Federal lands conveyed to the state. Native Allotments:In 1906 Native individuals were allowed by the Native Allotment Act to file for allotments of up to 160 acres on unoccupied federal lands. Regional Corporation Selections:Lands selected by the Regional Corporations under provisions of ANCSA are selected similarly to those by the state.The project area lies within the boundaries of Cook Inlet Region,Inc.(CIRl)and Ahtna,Inc. Regional Corporation Selection Tentatively Approved:Corporation sel ected 1ands approved by the federal government for transference to the corporation. Region Corporation Selection Patented:·Federal lands conveyed to the corporation.Interim conveyence 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 Alaska Native Claims Settlement Act.The lands have traditionally been used for their commercial resource value,and sub- sistence hunting and fishing.These lands are located near villages or along rivers.The village receives the surface rights,the regional corporation receives the subsurface rights. E-9-8 Village Selection Patented:Village Selection conveyed to the Village Corporation by the BLM.Interim conveyence is allocated to the corporation if the selected lands had not been surveyed. Village corporations in the Cook Inlet Region receive village selected lands by reconveyence from the regional corporation,not the BLM.The procedure for conveyence and reconveyence in the Cook Inlet Region is except i ona 1 to ANCSA.Norma 1 procedures are that the Regi on and Village corporations select preferred lands and the BLM conveys lands rlirectly to the corporation. By 1971,lands in the Cook Inlet region had been patented to such an extent that the Native groups could not select their allocation of usable lands within a BLM requirement of contiquity.The BLM classifies these lands the Talkeetna Mountain Deficiency Lands. Public law 94-456 allows the Village Corporations to select lands in a checkerboard pattern.The BLM will convey a contiguous land selection to CIRI and CIRI will reconvey the a110ted lands selected by the villages.The deficiency lands,those that are not prime use lands, such as glaciers,are kept by the regional corporation after the land reconvejence to the vi 11 age •. State Selection Suspended:ANCSA resulted in the suspension of State. selected lands until Native selection had been conveyed.The Cook Inlet Land Exchange,Public Law 94-204,has an extensive Terms and Conditions document,which allows the State to acquire land after the conveyence of corporation selected lands to CIRl. Borough Approved or Patented:If state patented 1and is not reserved for a particular use a borough can select the land until it fulfills its enti1ement through a process similar to that used by the state in selecting federal lands. State classified lands are in addition to the basic land ownership classifications.Within the project area the State has classified various aliquot parts of townships as follows: Residential Land:Land classified residential because its physical features lie adjacent to development;it is near an existing road, proposed road or navigable waterway;it is suitable for single or multifamily dwellings at medium to high density;it provides adequate on or off-site services and facilities that can be developed for solid waste disposal,wastewater disposal and potable water delivery. State Planned Disposals:Those State lands plotted for subdivision development.Disposal categories include Remote Parcels,Agricultural Parcels,and Private Recreation Lands. Remote Parcels:There are two remote subdivisions located within the project area near Indian River.Lots are sold for private holding. E-9-9 ~, Agricultural land:Land classified agricultural because their location,physical features and climate may be suitable for agricultural use.The State either owns these lands or has sold them to private ownership. Private Recreation Land:land classified private recreation because its rural location,physical features or adjacent development is suitable for private,low-density recreational development.No land may be classified private recreation until present and potential public recreation needs in the area have been considered first. Public Recreation Land:land classified pUblic recreation because of its 1ocat ion,phys i ca 1 features or adj acent development are most appropriately used by the public as natural or developed recreation areas,scenic overlooks,waysides,parks,campsites,historic sites or hunting,fishing or boating access sites. Resource Management land:land classified resource management is an area ident ifi ed as contai ni ng surface or subsurface resources,(i .e., minerals,timber),that are especially suited to multiple-use manage- ment. Utility Land:Land classified utility does not lend itself to classi- fication under other categories because of small or irregular tract size or because its proposed use is not covered under other catego- ri es. Wildlife Habitat Land:land classified wildlife habitat is a primary resource value as habitat for wild mammals,birds,fish or other animals. Historically the Bureau of land Management (BlM)owned all the land in the project area except for some private parcels described below.The BlM hasi nterimly conveyed lands adjacent to the Sus i tna River to the Cook Inlet Region,Inc.(CIR!)and associated Native villages.Other 1 ands from the Stephan Lake area eastward to the Kosi na Creek drai nage have been selected by CIRI.The State has selected entitlements on the north and south sides of the proposed reservoir between the remaining federal lands and the Native selected lands.In the areas designated for the Cook Inlet land trade,the State will select all those lands that are not selected by the Natives. Federally owned lands occur north and south of the Native Selected lands adjacent to the Susitna River.The National Park Service admini~ sters Denali National Park and Preserve.Remaining federal holdings are administered by the Bureau of land Management,the Alaska Railroad, and the U.S.Departments of Army or Ai r Force withi n the Anchorage to Willow transmission corridor.Railroad holdings exist along the Railbelt corridor east of Denali State Park north end of Healy. E-9-l0 The majority of state lands north of the impoundment are in various stages of the state selection process,either classified as selected, selection suspended,or as tentatively approved or patented.Lands within the Fairbanks to Healy transmission corridor are predominantly state-patented mixed with private,borough and a few regional holdings. Nearly all of the Anchorage-Willow transmission line is on State land. The Point MacKenzie Agricultural lands,in the Willow-Anchorage trans- mission line corridor,are the only agricultural lands within the project area. Two state land disposal sites (Figure E.9.2)exist near the Indian River in the western-most part of the project area,north of the Susitna River.The Indian River Subdivision (T33N,R2W,Seward Meridian)lies near mile 168 of the Parks Highway,northwest of Chul itna Butte,and contai ns approximately 518 hectares (1,280 acres) of land.The disposal area has been subdivided into roads and 139 lots averaging two hectares (five acres)per lot.The Indian River Remote Parcel,located northeast of the confluence of the Susitna and Indian Rivers is south of the Indian River Subdivision.This remote parce1 (T31-32N,R2W S.M.)is located east of,and adjacent to,Denali State Park.The Indian Riv"er Remote Parcel is 2,590 hectares (6,400 acres) of which 607 hectares (1,500 acres)will be divided into 75 parcels. These land disposals,along with scattered private parcels of land, represent the on1y actual dedication of a given piece of land to a particular use.Table E.9.1 displays various land holdings in the vicinity of the proposed project,and Table E.9.2 summarizes those holdings by status/ownership category. Placer mining occurs primarily on federal and state selected and patented lands near Ester. The majority of State Classified lands within the project area are either resource management or public recreation lands.The majority of resource management lands are located on state holdings west of the Susitna Ri ver.The remote parcel (southern portion)of the Indian River State Lands Disposa1 is under private recreation status. Private parcels occur along Ester Creek in a mining district at the north end of the Hea1y-Fairbanks transmission corridor,near Healy at the south end of the corridor. Matanuska-Susitna Borough owns no lands in the project impoundment area.Mat-Su Borough does own patented 1and in the Anchorage-Willow transmission corridor east of Knik Arm.The Municipality of Anchorage has patents to land at the south end of the Anchorage-Willow corridor. The Willow-Anchorage transmission corridor extends across Ft.Richard- son Military Reserves for 29 kilometers (18 miles)thence across E-9-11 ~.' Matanuska-Susitna Borough property located approximately 16 kilometers (10 miles)north of Anchorage.Approximately 6.5 kilometers (4 miles) of the line will traverse across the Point MacKenzie Agricultural Sale property that belongs to the state for sale of agricultural rights to private individuals for agricultural use.The remainder of the trans- mission line extends across state lands until the vicinity of Willow. At I~illow the study area encompasses state land disposal areas and pr i vate 1and interspersed withi n Mat-Su Borough Patented 1and.The selection of the proposed route avoided private lands to minimize the impact of the line to residents. The Healy-Fairbanks transmission corridor exte'nds across state-selected 1 ands,much of whi ch has been patented or tent at i vely approved.The line traverses the U.S.Air Force Clear Mews Military Reserve lands for approximately 16 kilometers (10 miles)in the vicinity of Anderson. The transmission route between Healy and Fairbanks will pass several 1 and di sposal areas on the west si de of the Parks Hi ghway.The pro- posed lines will parallel an existing transmission line when traversing the disposal areas. 2.2 -Description of Existing Land Use in the Project Area (a)Description of Land Use Evaluation Procedures Specific procedures and steps involved in the land use analysis are discussed below. (i)Study Areas Based upon preliminary project descriptions,three study areas (Zones 1,2,and 3)were defined for existing land use analysis (Figure E.9.4).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 Gold Creek and the mouth of the Tyone River. Zone 1 i ncl udes those structures and 1and uses that woul d be affected by inundation.Zone 2,extending about 10 kilometers (six miles)from Zone 1,is based upon the loca~ tions of lakes which characterize aggregations of land use. Zone 3~that extends approximately 19 kilometers (12 miles) beyond Zone 2,is distinguished by fewer aggregations of land use;existing structures and land use are sparse.In addit i on to an assessment of the effects of the dams and impoundments and closely related facilities,the land use analysis also involved evaluating the impacts of the transmission line routes.To investigate these concerns E-9-l2 ----.,-_._.__"'~--~---- A general literature search was initially conducted to determi ne what 1and 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 pub 1ic agency documents were acqui red and researched. (iii)Aerial Photography and Map Reconnaissance Aerial photographs and topographic maps were used to locate certain cultural features such as trails t habitations,and other indications of past and present land use.Old maps from hi stor i ca 1 texts and ear ly geo 1ogi ca 1 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 vehicles (ATV)access,tractor trails,roads, landing strips,and guide camp locations. (iv)Interviews Two types of.i ntervi ewi ng were used.Oral hi story i nter- vi ewi ng was undertaken to reconstruct a 1and and resource use history of the upper Susitna basin.This history focuses primarily on the area surrounding the Susitna River between Gold Creek and the Denali Highway,the area in which the proposed project would be located.Consideration of adjacent areas was necessary,however,to put the history of the project area into perspective.The inter- views were nondirected,in that,whi1e there was specific format and data needs,the interview was conducted so as to appear i nfor1l1al to the respondent.The i ntervi ew process and a 1ist of interviewees are available in Subtask 7.07 of Alaska Power Authority,Susitna Hydroelectric Project t Environmenta1 Studies,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 di recti on,and a lternat i ve future management strategi es dependi ng upon whether or not the Susitna Hydroelectric Project is built.Management agencies contacted and the questions asked of agency E-9-13 (v) (vi ) personnel are avail ab1 e 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. 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 duri ng the interviews.Field surveys were approached from a dual perspective:by aerial surveys and by ground verification surveys.Field surveys in proposed development locations were employed to locate important natural features and to estimate potential impacts on the area's 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 truthing.These priorities were based on:sites of historic interest,and sites for which limited information was available. Compilation of Land Use Inventory Land use data were summarized both chronologically and geographically.Since land use was analyzed within a temporal as well as a geographi c context,time cut-offs and zone boundaries were established for analysis and expres- sion 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 act iv ity,1 and status and ownershi p patterns,management activitY,and natural features was summarized. - (vii)Access Road and Transmission Line Analyses Land use and aesthetics were considerations in the evalua- tion of alternative routes for the access road and select- ion of the recommended corridor and route for transmission lines.Techniques specific to these project components were employed both in the selection process and in the impact assessment for the proposed routes. (viii)Project Impact Assessment Various project facilities were assessed to identify changes in baseline land use likely to occur as a result of E-9-14 the project.Impacts were determined by making qualitative and quantitative estimates of the potential changes in the baseline land use. (xi)Mitigation Mitigative measures that would minimize project impacts were identified.In some cases,project impacts have been reduced through selection of·design options having less impact than others.Where this was not possible,mitiga- tive proposals have been identified for consideration in subsequent planning and design refinement. (b)Existing Land Use Activity Land use aggregations for recreation,mining,and residential activi- ties are shown in Figure E.9.5. (i)Zone 1 Little activity in the way of trapping and m1n1ng currently takes place in Zone 1,especially compared to those pur- suits 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. River-related activities include river boating and float- ing.Boating within the project area has been linked with research,fishing.and recreation.Raft float trips are taken from the Denali Hi ghwayon the Susitna or Tyone rivers down to above either Vee or Devi 1 Canyons.Some portage between the lakes in the Stephan Lake vicinity and Prairie Creek to Talkeetna via the Talkeetna River. 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 nundat i on zone and adjacent areas.These studies combined have probably contributed more total man-days of use in the area in the past twenty years than a 11 other uses. (ii)Zone 2 and Zone 3 Zone 2 is the area extending about ten kilometers (six mil es)from Zone 1.Thus,Zone 2 encompasses the area downstream of 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 E-9-15 Susitna as far as Portage Creek.Individual and riverboat operations out of Talkeetna travel up the Susitna River, offeri ng servi ces that i ncl ude day tri ps 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 Devil Canyon to Talkeetna. -Hunting Lodges typi ca 11y handl e 15 to 25 guests at a time and about 140 guests per season.The i ncreasi ng popul arity of sport hunting in the 1960's caused an increase in the number of small cabins on many of the lakes in the pro- ject area.Both guided and non-guided hunting occur wi thi n the project area,part i cul ar ly near Stephan,Fog, Cl arence,Watana,Deadman,Tsusena,and Bi g Lakes in addit i on to many of the area 1 s small er 1akes.Both lodges and cabins provide the field bases for many hunters. -Fishing Fishing in the project area occurs either as a separate pursuit or in close association with other activities, such as hunting and trapping.Fish present in the area's lakes and streams include burbot,grayling,rainbow trout,Dolly Varden,lake trout,and whitefish.Consi- derable fishing for lake trout,grayling,and salmon occurs in the Stephan Lake -Prairie Creek drainage. Salmon fishing occ~rs in lower Portage and Chunilna (Clear)Creeks and Indian River.Fishing in Fog, Cl arence,Watana,Tsusena,Deadman,Bi g,and Hi gh 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. -Trapping Present trapping in the project area occurs mostly on the south side of the Susitna Ri ver near Stephan and Fog Lakes.Some trappi ng al so occurs near Tsusena Creek and Cl arence and Hi gh Lakes.Tr aps are set sporad i ca 11y by aerial trappers in the easternmost portions of the Susitna valley. -Mining Mineral exploration and mlnlng have been limited in the immediate project area.Mining in the Upper Susitna River basin has been low in claims density and charac- terized by intermittent activity since the 1930 1 s. E-9-16 Placer mines working alluvial deposits for minerals are found in sites throughout Mat-Su Borough.Active mining has been more concentrated in Gold,Chunilna (Clear),and Portage Creeks than in other areas of the upper Susitna basin.Other acti ve cl aims 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. (c)Existing Land Use Development Both historically and currently,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 artifacts have been utilized for hunting,fishing,trapping,boat- ing,mining,and other geneneral recreation purposes,such as cross-country skiing or photography.Existing structures in the project area are shown in Figure E.9.6. (i)Zone 1 Types of developments located in Zone 1,the i nundat ion zone plus 61 meters (200 feet),include structures,trails, and airstri ps. 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 ntai ned 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. (ii)Zone 2 The greatest number of existing land use development and historical artifacts are located in Zone 2.Zone 2 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 arti- facts consist of hunting,trapping,fishing,boating,min- ing,recreation,and research. Although the primary distribution of use throughout the project area is low density,the aggregations of existing development is particularly noteworthy.The nuclei of these aggregations are the small lakes and lake systems located throughout Zone 2 that provide access by air.The aggregat ions of development cons i st of cabi ns and rel ated structures~lodges,roads,trails,and airstrips. E-9-17 - - 1I0OI'\, - ..... - (i i i )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. Figure E.9.5 identifies the location of land use activities and quantifies the intensity of use. Land use between Montana and Willow is sparse with a Matanuska Electric Association right-of-way located several miles east of the Parks Highway.Some vacant and low density residential lands are present along Fishook Willow Road (Hatcher Pass Road).Homesteads occur along Montana Creek.Four private landing strips and a registered public airport are in the Montana area. La nd use east of Ta 1keetna and Chase is domi nated by the land disposals along the Talkeetna River.Parcels within the Talkeetna Agricultural Disposal are available for agri- cultural use.A few homesteads exist around Larson Lake. The Larson Lake residents could develop the lake for resi- dential recreation.There are five landing strips in the Talkeetna area.The two within the village of Talkeetna are registered public landing strips. Residential and commercial land development is west of Curry Ri dge and along Petersvi 11 e 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 principle concentration are where residents desire to keep the land in a natural,pristine conditions. Within the Curry area is Byers Lake State Campground. Hik i ng trail s 1ead from Byers Lake State Campground to Curry Ridge and Troublesome Creek. Land use development east of Curry Ridge along the Alaska Railroad includes the Indian·River Land Disposal and the Indian River Remote Parcel.Both are recreation oriented. The Disposal is surveyed into 5 acre lots having utility easements.Only a limited 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 dwe 11 i ng.The Remote Parcel E-9-18 will have a specific number of residents able to obtain lots ranging between 2 and 16 hectares (5 and 40 acres). Homesteads occur along the Alaska Railroad at Chulitna, Gold Creek,and the Susitna and Indian Ri verso There are two pri vate 1 andi ng stri ps at Gold Creek,one at Curry ·and Chul itna. Land use development between the Middle Fork and East Fork 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 establ ished at Cantwell,Summit and Broad Pass.Land use development such as the Cantwell Community Center,is expected 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 1andi ng stri ps in the Summit area.Al so present are the Parks Highway,the Alaska railroad and the eastern boundary of Denali National Park and Preserve. Residential and commercial land use developments exist along the Nenana Ri ver and the Park s Hi ghway near the Denali 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 commer- cial land use around the Healy Generating Station.Other developed land use near the northern transmission corridor is low density residential with travel-oriented commercial developments located along the Parks Highway.Two private landing strips are located in Healy. (d)Special Lands (i)Wetlands Proposed land use development is contingent on wetland and floodland locations.Wetlands are biologically important because they tend to be more productive and generally support a greater diversity of wildl ife species per unit area than most other habitat types in Al aska.Ri pari an wetlands 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. Wetlands cover large portions of the upper Susitna river basin including riparian zones along the mainstem Susitna, sloughs,and tributary streams,and numerous lakes and ponds on upland plateaus.In addition,extensive areas of wet sedge-grass tundra are classified as wetlands by the U.S.Arrrry Corps of Engineers for purposes of Section 404 permitti ng. E-9-19 - Wetl ands of the project area are descri bed in Exhi bit E, ro~Chapter 3,Subsection 3.3. (in Floodlands Fl oodl ands are areas known to be frequently inundated by high water run-off,glacial outbursts,high tide or by water from high winds. Floodplains are composed of sediments transported and deposited above the riverbanks by flooding rivers or streams.Land use development is not compatible within fl oodpl ai ns. The National Oceanic and Atmospheric Administration does not have an office of Coastal Zone Management in Alaska. The U.S.Corps of Engineers,Floodplain Management,con- ducts hydraulic'analysis of floodlands to determine flood- plains for the Federal Insurance Program of the Federal Emergency Management Agency (FEMA).Speci a 1 area mana ge- ment plans are prepared for FEMA in areas of potential land use development where floodplains have not been delineated. No such management pl ans have been prepared in the upper Susitna basin due to the area remoteness. - The Chul itna, ri vers in the i dent ifi ed. Susitna Ri ver (iii)Prime Lands Talkeetna,and Nenana Ri vers are the major project area for which floodlands have been Floodlands have been identified for the downstream from Devil Canyon to Talkeetna. The U.S.Soil Conservation Service has determined that there are no prime farmlands,rangelands or forests within -the Upper Susitna Basin. 2.3 -Description of Existing Land Use Management Plans for the Project Area The Bureau of Land Management (BLM),the Alaska Department of Natural Resources,Matanuska-Susitna Borough (Mat-Su Borough),and the Cook Inlet Region,Inc.(CIRl)and associated village corporations have various mangement concerns in the project area.Table E.9.5 summarizes the existing and proposed land use management activities of these agencies. Federa 1 1ands to the north of the project area are managed by the BLM.These lands are included in the DenalilTiekel Planning Blocks (Figure E.9.7).A Decision Record;dated July 1982,authorized the Denal i/T;ekel Amendment to the Southcentral Management Framework Pl an E-9-20 to be a Fi ndi ng Of No Si gni fi cant Impact (FONSI).The attachment of the Decision Record authorizes the Draft report to be final.The planning 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 State is essentially passive.Very few management activities are taking place.BLMls objective is to protect the natural environment of the area,with particular attention to caribou calving areas and river recreation routes.Fire control is al so a current management consideration.BLM has a cooperative fire control agreement with the State of Alaska that covers the project area. Lands in the project area that have been identified for conveyance to the Natives have a total of six easements across them.These include: an access trail 15 meters (50 feet)wide from the Chulitna wayside on the Alaska Railroad to public lands immediately east of Portage Creek; a state site easement and easements on Stephan Lake;and an access trai 1 runni n9 east from Gol d Creek.Easements were only reserved when it was shown that access to public lands was not possible from any other public land area.There are no easements immediately adjacent to the Susitna River above Gold Creek. Finally,BLM is also developing a wildlife habitat management plan in cooperation with Alaska Department of Fish and Game (ADF&G)for the Alphabet Hills between the Tyone and Maclare·n Rivers (Tl1-12N,R2-9W, Copper River Meridian).This plan will involve moose habitat manipula- t i on.As yet,however,only study plots for thi s project have been mapped out. Most state lands fall under the jurisdiction of the Alaska Department of Natural Resources (DNR).As indicated,the State is disposing of 607 hectares (1,500 acres)of remote housing parcels and 518 hectares (1280 acres)in a subdivision.These disposal areas (located north and south of Chulitna)are west of the project area.They are included in Mat-Su Borough's Talkeetna Mountain Special Use District. In the project area,the State had,until recently,done only a resource assessment for those lands it is proposing to select.Cur- rently,DNRls Division of Research and Development is undertaking a comprehensive assessment of the resource base in general.The Susitna Area Plan for state lands in this area is being developed in coopera- t i on with Mat-Su Borough.The State has requested coordi nat i on between the Susitna Hydroelectric Project and the regional land use plan. Matanuska-Susitna 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 Dis- trict,and the Mat-Su Borough Coastal Management Program.The current Mat-Su Borough Comprehensive Plan (1978).contains very little discuss- ion of the Susitna area lands.The borough has already selected more than its entitlement and is concentrating its selections in the lower Susitna basin near existing highways.Thus,it is unlikely that the borough will select any lands in the project area. E-9-21 - - - The borough,by ordinance,has created the Talkeetna Mountains Special .Use District,through which the borough can exercise planning and zon- ing authority over all lands within the district1s boundaries.The Special Use District includes the project area.The Indian River Sub- division and Remote parcel are within the special use district.The Mat-Su plan will allow recreation cabins at these sites but no perma- nent residences. The ordinance provides for multiple resource use of the district and takes into account unique scenic values.Thus,lands within the spe- cial 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.The project area is considered a mixed- use zone,which would premit hydro development.Management objectives for the project area will probably not be refined until the current hydro 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 Alaska Coastal Management Program (Division of Community Planning,Alaska Department of Community and Regional Affairs),Mat-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.9.8).At present the dam is not included within the program. The Cook Inlet Region,Inc.received conveyance of selected Native 1ands to hol din trust unt i 1 these 1 ands are conveyed to the appro- priate Villages (Chickaloon-Moose Creek,Tyonek,and Knik).Currently, no land management activities are being carried out.When the villages obtain their lands,the different village ownerships will create a checkerboard pattern.Immediate land problems and land reconveyance to vi 11 ages are bei ng handl ed by the Vi 11 age Defi ci ency Management Asso- ciation,a group made up of representatives from each of the concerned vi 11 ages.Because of the checkerboard pattern of ownershi p descri bed above,any management of Native lands may be undertaken by this associ- at ion. E-9-22 - 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 Alaska Power Authority1s FERC license application for the Susitna Hydroelectric Project. Construction and operation of the dams and related facilities will Cquse impacts on area resources.Pr i or to determi ni ng the extent of the land use changes,land use priorities were assessed in terms of land use activitya'od 'development or conservation and preservation of specific ecosystems.In few cases,these values are identified in agency management programs that apply to the area.Section 9.2.3 of Exhibit E described the Existing Land Use Management Plans.Section 4.0 discusses the changes in land use management plans resulting from the project. Project facilities,will create immediate,direct impacts on the 1 andscape.Some of these impacts wi 11 be temporary,such as the construct i on camps and construction acti vity.Other aspects of the project wi 11 create permanent and often subtl e changes in the type, nature,and intensity of development and activitiy.Chief among these aspects is the provi si on for automobil e access to an area currently remote.Further discussion of access related land use change is presented in Section 3.5 below. 3.1 ...Dams and Impoundment Areas (a)Proposed Facilities - (i) (i i) Watana The Watana Dam will be a 720 meter (885 foot)high, gravel-filled structure,with a crest length of 1,250 meter (4,100 feet).The dam will be located at Susitna River kilometer 266 (mil e 165),approximately three kilometers (two miles)upstream from the mouth of Tsusena Creek.It will impound approximately 80 kilometers (48 miles)of river to 666 meters (2,185 feet)elevation and inundate about 16,000 hectares (38,000 acres).A general layout of site facilities is shown on Plate F34. Devi 1 Canyon Devi 1 Canyon dam wi 11 be a 197-meter (645 foot),concrete thin-arch dam and a rock-fi 11 ed saddl e dam constructed at ri ver kilometer 216 (mil e 134)-j n Devil Canyon.Its crest 1ength will be 754 meters (2,475 feet).The dam will impound 42 k n ometers (26 mil es)of'ri ver to 444 meters (1,445 feet)elevation.Approximately 3,157 hectares (7,800 acres)of land will be inundated.A general layout of site facilities is shown on Plate F70. E-9-23 (b)Induced Land Use Changes (i)Land Use Development The emp1 acement of the Watana Dam and impoundment wi 11 inundate seven structures.These structures are numbered 90,91, 92,111,112 and 120 on Figure E.9.6.Two structures are actively maintained as indicated in Table. E.9.6.Number 90 is a lean-to for hunting and fishing purposes.Number 119 is a trailer situated by the U.S. Corps of Engi neers for Susitna Hydroe1 ectri c feas i bil ity study. The emp1 acement of Devi 1 Canyon Dam and impoundment wi 11 inundate three structures,as illustrated in Figure E.9.6. These are 2,6 and 107.As indicated on Table E.9.6,only Number 2,a boat cabin,is currently maintained for boating and hunting. (ii)Land Use Activity Hunting activity will increase,and current patterns will change as a result of impoundments.The reservoirs and access to them will facilitate f10atp1ant landing and boat travel,and thus,permit easier penetration by big game hunters into rarely visited·areas.An increase in moose hunting will occur immediately adjacent to the proposed impoundments.Hunting for caribou may increase to the maximum allowed by the permit system.Game will be reduced by the effects of increased hunti ng and by the resource emigration caused from increased human population.Big game hunting guides will be affected by reduced hunting activity and therefore reduced income.Guides may need to find a different occupation or move elsewhere. There is potential for increased fishing for resident species in tributaries feeding into the impoundments.A limited reservoir fishery may also develop.Salmon fishing in Portage Creek could increase due to the accessibility created for the Devil Canyon faci 1 ity.Regu1 at i onscan be requested to manage this fishery area. Fur resources will be eliminated in Zone 1 by the impound- ments.Access to the reservoirs will cause disruption of present trapping patterns within Zones 2 and 3. Access to the proposed facilities will be limited to project personnel duri ng constructi on of the facil it i es. Land use activities will be confined to project construct- i on to di scour age increased hunt i ng,fi shi ng and trappi ng in the project area.T~e 1 and management pl ans developed with the cooperation of jurisdictional agencies will include control of land use activities and will be E-9-24 - - 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 fur bearers resulting from increased land use activity. 3.2 -Construction Camps and Villages ,~ -I (a)Proposed Fa·cil.ities One construction camp (single worker housing),village (family housing),and assoc·iated facilities wil1.be"located at each dam- site within the immediate project area.Construction of Watana Dam is proposed to begin in 1985,nine years before the dam at Devil Canyon.Plans are to build a construction camp and village at Watana for use until the dam construction phases down.The camp wi 11 then be relocated to the Devi 1 Canyon dam site.Part of the village at Watana will remain as a permanent town to provide housing and community facilities for workers who will operate the dams.No permanent village is p1 anned for the Devil Canyon site. The proposed camp and village at Watana will be constructed nor.th- east of the dam site between Deadman and Tsusena Creeks (P1 ate F34).Approximately two kilometers (one mil e)wi 11 separate the construct i on camp from the vil1 age.Work on the vil1 age will begi n about one year after construct i on of the camp has begu n. Structures at the camp will be of factory-built,modular design to f acil itate thei r re 1ocat i on to Devil Canyon.Permanent buil di ngs are planned for the village facilities at Watana,since the vi 11 age community wi 11 remai n after the dams are buil t. Facilities at the village will include family housing (to accommo- date about 1000 people),a school,gymnasium,recreation center, shopping center (food supermarket,department and specialty stores),fire station,generating station,and structures for other support activities.Facilities and services to be provided at the costruction camp include housing modules (dormitories)for about 3,000 workers,camp offices,food services,warehousing, fire and security protection,banking and postal services,hospi- tal care,recreation,communications,and power generation. Camp and village utilities will include a potable water supply system,sewage system,power supply and di stri buti on system, communications,fuel storage,and a solid waste disposal system. The water supply is expected to serve an estimated peak population of 4,030 (3,070 in the camp and 960 in the village)including workers,families,and visitors.The water source will be from Tsusena Creek and groundwater wells.The treatment plant,also of modular design,will fulfill Environmental Protection Agency (EPA) requirements. E-9-25 Permanent facilities required for project operation at Watana include a small community of approximately 130 staff members and their families.The town is planned at the site of the construction village. The facil ities at the Devil Canyon construction camp and village will be s imil ar to those at Watana,though fewer workers will be accommodated.Up to 1900 peop1 e wi 11 be housed dur i ng the peak construction period at Devil Canyon.The camp will be situated south of Portage Creek and west of Devil Canyon on the south side of the Sus i tna ~i ver.The vi 11 age wi 11 .be temporary,un1 ike the one at Watana,and will be west of the camp (Plate F70). Additional details on the construction camps and villages may be found in Exhibit A and in Section 5 of Exhibit E. (b)Induced Land Use Changes (i)Watana -Land Use Development The construction camp and village will result in the dedication of 150 hectares (370 acres)to community use dur i ng the construct i on phase.After construct i on has been completed and the camp and temporary village removed,the permanent town at Watana wi 11 occupy 36 hectares (90 acres).Additional lands will be required for connecting roads,an airstrip,and other facilities related to dam construction. -Land Use Activity Among the project I s effects upon act i vi ty patterns are those impacts related to access.The chief effect of the Watana camp wi 11 be the acti vity associ ated with the ten-year construction period.The extent of impact on general patterns of activity in the Upper Susitna basin will depend on the actual operating policies established for the camp duri ng the construct i on peri ode Di spersed recreational activity by construction workers could increase significantly in the absence of such policies. Conversely,if there are extensive policies limiting dispersed recreation and other activities outside of camp,the effects on the basin will be minimized. (ii)Devil Canyon -Land Use Development Some 34 hectares (85 acres)of presently undeveloped land wi11 be converted to commu nity uses for the construct ion period.Additiona1 areas will be required for connecting E-9-26 - - - - roads and related facilities.After construction is complete in 2002,all camp and village facilities will be removed. -Land Use Activity The chi ef effects of the Devi 1 Canyon camp wi 11 be the associ ated construction acti vity dur i ng the constructi on period from 1994 to 2002.Controlled activities outside of camp will determine the extent the construction workers wi 11 impact the activity patt~rn.Change in the activity pattern is expected to be less than that for Watana because of the smaller work force required for Devi 1 Canyon. (c)Mitigation Impacts from human use can be reduced if trails outside the proposed camps are established and if specific areas are designed for leisure activity.Impacts from facilities associated with housing,such as sewage treatment lagoons and landfills,can be reduced if they are located away from existing or proposed developments. Posting and enforcing construction camp rules will help make project personnel aware of adverse environmental impacts.Other mitigations measures may include restricting the use of private vehicles in the project area. 3.3 -Access (a)Proposed Facilities The access pl an proposed route is shown on Pl ate F32.Transport to the Watana damsite will commence in part at the existing Alaska Railroad at Cantwell.A road will extend 3.2 kilometers (2 miles) from a proposed rail marshall i ng yard and storaage facil i ty,and will follow an existing route to the junction of the George Parks and Denal i Hi ghways.Transport will proceed east 34 kilometers (21 miles)on the Denali Highway.A new access road will extend south from the Denali Highway from a point south of Pyramid Peak. The road will be constructed for 69 kilometers (43 miles)across Brushkana Creek,paralleling a drainage west of Deadman Mountain and Big Lake to the Watana damsite.The road will provide access to some Native lands on the north side of the river and access to Native lands on the south side of the river when access is provided across the top of the dam. Access to the Devil Canyon development will cons;st pri marily of an 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 distributed using a system of site roads. E-9-27 The railroad will climb gently and steadily for 22.5 kilometers (14 miles)from Gold Creek to the marshalling yard near the Devil Canyon camp,except for a 3.2 k i 1 ometer (2 mil e)secti on where the route traverses steep terrain alongside the Susitna River. Several streams are crossed requiri ng the constructi on of 1arge culverts,however,no bridges are needed. The railroad extension will be designed not to exceed a maximum grade of 2.5 percent nor a maximum curvature of 10 degrees.These parameters are cons i stent wi th those presently bei ng used by the I!!li!!'! Alaska Railroad. A road will connect the Devil Canyon and Watana damsite.This road connection is also required for travel between Watana and Devil Canyon by the post-construct ion operati on and mai ntenance personnel who will be stationed at Watana. From the marshall i ng yard at Devi 1 Canyon the connecti ng road "Ii 11 be built to a hi~h level suspension bridge approximately 1.6 kilometers (one mile)downstream of the dam site.The route extends northeast,across Devil Creek and past Swimming Bear Lake at an elevation of 1,400 meters (3,500 feet),thence southeast through a wide pass.The road continues south crossing Tsusena Creek and connects to the Watana Dam.The overall length of the road is 57.5 kilometers (36 miles)between Devil Canyon and Watana. Assessment of projected traffic volumes and loadings during construction resulted in the selection of the following design parameters for the access roads. -'I ~i Surfacing Width of Running Surface Shoulder Width Maximum Grade Maximum Curvature Unpaved 24 feet 5 feet 6% 50 The 33.5 kilometers (21 miles)of the Denali Highway will be upgraded to these design standards.The connecting road between Watana and Devil Canyon will be bui 1t to these standards. Grades and curvatures consistent with current highway design standards for a 90 km/h (55 mph)design speed were chosen for the efficient and economical movement of supplies.As extensive grades and curvatures could result at some locations,the design speed will be reduced in certain areas to 65 km/h (40 mph)to a 11 ow steeper grades and shorter turn radi i.F1 exi bil ity of design speed allows the road to follow the topographical contour more closely. E-9-28 - (b) Typi cally the crown of the road will be approximately 1.2 meters (4 feet)above natural elevations.Side slopes will be smoothed. Several pull-outs will be constructed along the access road to permit vi ewi ng of natural areas and some of the project fa c il it i es • Required right-of-way width will generally be 60 meters (200 feet) for the gentle to moderate side slopes of the road and railroad. The few areas of major sidehill cutting and deep excavation will require additional width. The road will be paved in the community of Cantwell from the 16 hectare (40 acre)marshalling yard to 6.5 kilometers (4 miles) east of the George Park and Denali Highway intersection.This will eliminate dust and flying stones.in the residential district. Allowable speeds will be lowered along this segment for safety measures. Induced Land Use Changes The access route will be built for construction an~operation of the dam facilites.Many of the effects will be related to long- term consequences after construction is complete.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- tion development.Access will introduce an influx of people and will instigate activity within the basin that will affect population concentrations,isolated residences,peripheral commercial establishments and transportation systems,resource utilization,the level of recreation activity,and the overall character of the area.These effects coul d i nfl uence changes in land 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 discussed in Chapter 9.3.3 (b)(i).Road access will cause both the disrup- t i on of present 1and use and the inducement of future 1and use. Provision of access into the Susitna basin is a more significant impact than is the physical road.The provisions of easy,inex- pensive access into the area will cause profound alterations to the Susitna basin's character. Rail access to Devil Canyon originating at Gold Creek,will allow the transportation of materials,equipment,and labor through Gold Creek.There waul d be a si gni fi cant impact on Go 1d Creek and on Hurricane and Talkeetna,the last railroad junctures with highway access to the north and south of Gold Creek,respectively.The use of the railroad to ship materials to Devil Canyon Dam will cause 1ess of an impact to other communities along the Parks Highway. £-9-29 _____~• =,_---e___'-------------------- Goods or peop1 e cou1 d travel by rail to the Devil Canyon site. This will reduce the extent of impact on community land use along the Parks Highway.Access by road from the Denali Highway to Watana,would increase off-road vehicle use in areas where it is now low.This introduction could aggrevate alterations to the terrai n. The proposed access would likely cause less of an effect to residents along the Parks Highway since direct access from the Parks Hi ghway is prec1 uded.The road from the Denali Hi ghway 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 wou1 d be reduced with access extendi ng from the Dena1 i Highway due to the increased distance from Anchorage.In addition,virtually no development exists along the Denali route, so disruptions to existing land use would be minimal. The Denali access road wi 11 provide access to CIRI and vi 11 age corporation lands for possible resource development.This is considered as a positive step by the corporations.Recreation, mining,and timber harvesting have been suggested as possible activities. (i)Land Use Development Improved access,increased use and markets for commerci a1 services wi 11 make the 1 and in the project vi ci nity more attractive to prospective commercial and residential buyers.Commercial and residential development may increase,escalating the land value. The access road that extends from the Dena1 i Hi ghway to Watana and Devil Canyon,and the railhead at Cantwell will not directly create significant impacts on land use development.Their construct i on will create jobs duri ng constructi on and operat i on.The indirect i nf1 uence the access road will have on the local communities will be more significant as labor and materials pass within their vi ci nity. The termination of the rail system at Cantwell,the closest community to the dam sites via road,will create a signifi- cant change to Cantwell.Support sector employment will develop as personnel arrive that are directly employed toward the construction or operation of the proposed faci- lities.As the community population increases,housing, business activity,improved transportation and schools will require development and construction within the community. E-9-30 -. ~. - f/lII>? - (i i) The popu1 at i on may increase over 100 percent at Cantwell and up to 100 percent at Trapper Creek.Talkeetna will experience a 10-50 percent increase in population with the Denali-North access plan.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 increase will be experienced in the development of service sector employment,business activity and transportation facil ities. The railroad wi 11 traverse through Go1 d Creek to a rai 1 head at Devil Canyon.This rail spur will signifiant1y impact population,and the development of support sector employ- ment,business activity,housing and transportation in Gold Creek and,to a 1esser extent,Ta 1keetna.Ta 1keetna wi 11 experience a significant impact on its schools and other public facilities services. The extent of land use development in surrounding communi- ties will depend on the transportation program employed .which could include combinations of airplane,bus,personal vehi c1e with associ ated park and ride lots,travel sche- dules,and/or travel allowances. Information on socioeconomic impacts is described in Section 5,Exhibit E of Alaska Power Authority's FERC 1icen~e application for the Susitna Hydroelectric Project. Land Use Activity There will be increased hu nt i ng for moose and bear along the access corridor.The increased number of hunters will disrupt existing hunters and force them to adjust to reduced resources or to relocate into other remote areas. Fishing will increase with potential effects on reduced resources and on people who currently fish in the area. The access road between the two dams on the north side of the Susitna will disrupt current use patterns at High Lake Lodge.Disruption might also occur to fly-in fishing and hunt i ng around the 1akes near Devil Canyon.Some trappi ng .territories recently established around the High Lake area would also be altered.In addition to increased hunting and fishing,this area will also receive increased recrea- tional use for hiking,backpacking,sightseeing,and other act i vit ie s. E-9-31 (c)Mitigation Access will be limited to project personnel during construction. Land use activity will be confined to project construction until the facilities are built.This will reduce in impact of land use activity until the implementation of the land use management plans are in effect. If the use of off-road vehicles originating from the access route becomes a disturbance,measures will need to be taken to inhibit this activity.Such measures would include:a buffer strip des i gnated for non-motor i zed use adj acent to the access route; natural conditions employed as subtle but absolute deterrents to ORV use;designated and planned ORV trails in locations that will neither conflict with other land uses nor damage the environment; and if necessarYt ORV restriction such as between the proposed dam sites.Spur roads to private holdings and mining claims will be designed t located,and constructed t similarly. Recreat i onal use extendi ng from the access route wi 11 be directed to sites designed to support such use. 3.4 -Transmission (a)Proposed Facilities Maps of the transmission route are included in Exhibit G.From Watana to Devil Canyon,two single-circuit lines will be constructed in a 122 meter (400 foot)wide right-of-way specified within the proposed 0.8 Kilometers (0.5 miles)wide corridor. Five single-circuit 345 Kv lines will extend from Devil Canyon to the intertie near Gold Creek.A 213 meter (700 foot)wide right- of-way will be selected from the proposed Devil Canyon-Gold Creek Corridor.Watana to Gold Creek was considered the central study area. From Gold Creek,two lines will extend north and three lines will extend south and will parallel the intertie to Healy and Willow t respectively.From Healy to Fairbanks and from Willow to Anchorage,the northern and southern study areas,respecti vely, the right-of-way will be approximately 122 meters (400 feet) wide. Most of the towers will be X-shaped structures approximately 30 meters (lOa feet)tall.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 except 15 meters (50 feet)taller. E-9-32 - -I - -- -, -- I"- , The corridor width studied was 5 to 10 kilometers (3 to 6 miles). It included both sides of the river so therefore was 23 kilometers (14 miles)wide in some central corridor segments.The trans- mission route analysis involved mapping within the corridor the following land use features:development and activity,land tenure~and aesthetics. The process of environmentally screening the original 22 corridors involved comparison of study area options based on the folloWing 8 constraints categories:length,topography/soils~land use~ aesthetics,cultural resources,vegetation~fish,and wildlife. Following review of the environmental and engineering ana1yses~ one transmission corridor was selected for each of the three study areas.Constraints within that corridor were then examined and a 0.8 kilometers (0.5 miles)wide route within the corridor was selected. The transmi ssi on 1i ne ri ght-of-way for two 345 KV 1i nes wi 11 extend west from the substation north of Watana Dam,in the Southwest Quarter of Section 28~Township 28 North,Range 5 West of the Fairbanks Meridian,for 8 kilometers (5 miles).The corri- dor is proposed to be north of the Susitna Ri ver and to cross Tsusena Creek.The corridor extends southwest for 9.5 kilometers (6 miles)thence west for 16 kilometers (10 miles)crossing the Susitna Ri ver.The corridor continues west by northwest for 21 kilometers (13 miles).The proposed Gold Creek Substation is in the Southeast Quarter of Section 36~Township 32 North~Range 11 West of the Fairbanks Meridian. The transmission line will be built during winter to reduce the impact of the construction vehicles on the terrain.Access to the transmission line wi 11 be over snow andice bridges across the Susitna River~Tsusena Creek and the other drainages traversed~to the greatest extent practical.Access from the proposed Gold Creek Substation to the drainage that extends south from the proposed Devil Canyon dam will be along the alternative Access Plan 16.A description of the Access route is presented in Section 2.6 of Exhibit B. Cross i ng the steep walls of the dra i nage south of the proposed Devil Canyon dam will be diffi cult and may require foll owi ng the contours of the drai nage south to a 1ocat i on offer i ng safe and economical crossing of the drainage.A similar detour from the transmission corridor may extend north at the Tsusena Creek drainage.Vehicles may need to extend upstream along other dra i nages and around peaks before returni ng to the transmi ss ion 1 ine corridor for construction.It is possible that the trans- mission line extending for 8 kilometers (5 miles)west of the Susitna River will require helicopter construction during the summer.Upon worst case,summer helicopter construction could be required for approximately 32 kilometers (20 miles)between Tsusena Creek and the drainage south of the proposed Devil Canyon dam. E-9-33 (b)Induced Land Use Changes Construction activities cause both short-and long-term impacts on resources.The creation of new access will add si gnifi cant ly to the potential for disturbance caused by the transmission line. Efforts were made to parallel existi ng util ity corridors.and to utilize existing access wherever appropriate. Maintenance activities during the operational phase of the lines can also cause adverse impacts as a result of clearing or of chemical treatment of the right-of-way.Impacts will vary depend- ing upon the timing and method of right-of-way maintenance and can be minimized thro~gh careful prescription of maintenance techni ques. (i)Land Use Development The Wi 11 ow-Anchorage route crosses or parall el s numerous trails,including the Iditarod Trail.seismic survey lines, tractor and pioneering ORV trails.and several recreational trails near Willow. Residential use occurs in Willow,Red Shirt Lake,and on many of the small lakes east of the Willow-Anchorage route. Scattered cabins in the vicinity of Willow are close to the Alaska Railroad and Parks Highway.Red Shirt Lake has approximate ly 25 cabi ns along its shores.Seven other lakes have several cabins along their shores,and a few cabins are widely scattered el sewhere.The proposed route will 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. Agricultural.use occurs north of Point MacKenzie,and agricultural clearings exist from a region northeast of Middle Lake east·to the Little Susitna River south of Yohn Lake.Land within a transmission right-of-way can still be cultivated,the towers would displace small areas of exist- ing and potential farmland and disrupt normal patterns of cultivation and future agricultural development. The corridor and portions of the western boundary of the Willow-Anchorage route include the northeast corner of the Susitna Fl ats State Game Refuge.All 1and use development in a Game Refuge must be determined to be compatible with the purposes for which the refuge was created. The proposed lines extending south from Willow will parallel the existing Chugach Electric Association,Inc.'s Point MacKenzie-University Substation line on the east side of Knik Arm to a new substation proposed south of Muldoon E-9-34 - - - - ~I ..., - ..- - Road.The visual impacts of this section of line will not b~insignificant since it is located on the Fort Richardson Mi 1i tary Reservat i on.The impacts of the proposed route will be reduced because it is adjacent to an existing line. Additional mitigation measures include imitating the tower and conductor materials,tower spacing,and design of Chugach EA's existing line. The impact of the transmission line routes from Gold Creek to Healy and Willow will be minimal because the routes will be ·within the same corridor as Alaska Power Authority's Healy-Willow intertie transmission line.The construction of Alaska Power Authority's Healy-Willow intertie will be complete upon commencement of the proposed transmission construction.The impact of the proposed transmission 1i nes wi 11 be reduced because they will para 11 eland be adjacent to the approved intertie right-of-way. There are several moderate concentrations of land use developments along or adjacent to the proposed route between Healy and Fa irbanks.Si gnifi cant among these is the development at Healy,Nenana,and Ester.In Healy and Ester,existing land use and the proposed transmission route will be juxtaposed. (i i )Land Use Act i vity The proposed route between Wi 11 ow and Knik Arm northeast of Point MacKenzie will traverse an area that receives dispersed but increasing use.Boating occurs along the Susitna and Little Susitna Rivers,Willow Creek and on numerous small 1akes.Potential confl i cts between the proposed lines and private lands and boating use may occur wherever the lines and towers will be visible.Floatplane f1 i ght patterns may be affected where the 1i nes pass near lakes used for landing and taking off. Tr ails that recei ve substant i a1 ORV use are located near Wi 11 ow,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. (c)Mitigation Efforts were made to select transmission line routes that would mi nimi ze negative impact.Proper al i gnment of the transmiss ion line right-of-way within the route could reduce the line's obtrusiveness.The techniques employed by the U.S.Fish and Wildlife right-of-way management plans will be used when selecting the transmission lines right-of-way. E-9-35 - ,.,.. ,- 4 DESCRIPTION OF CHANGES IN LAND USE MANAGEMENT RESULTING FROM THE PROJECT 4.1 -Land Acguisition With the exception of a few scattered parcels,most lands in the pro- ject area are presently under federal control.Much of the land required for the dams and impoundments has been selected by the Natives under Alaska Native Claims Settlement Act.Many lands such as the pro~osed locations for the Devil Canyon camp and village,as shown in Figures 4 and 5,have been selected by Cook Inlet Region,Inc.(CIRI) and could be transferred to CIRI and associated Native village groups. Approximately 16 kilometers (10 miles)of the access route crosses Native Selected lands.The remainder of the access route is on federal or state selected lands.The relocation of the preferred access route could cause the reevaluation of village selection lands by the Natives. The transmission line routes are primarily on State land with the exception of the central route.Twenty-nine kilometers (18 miles)of the selected transmission 1 ine from Watana to Gold Creek traverses Native Selections.The remainder of the central transmission route is on State selected lands. Sect ions of the northern transmi ssi on corridor crosses Doyon Regional Corporation lands that have been designated for village selection by the Alaska Natives.Sections of the southern corridor are owned by CIRI. Before the initiation of construction,a means of land acquisition will have to be established for the access road and transmission line corridor ,either throl1gh purchase or by obtaining a right-of-way. A decision by the State to proceed with the Susitna project would entail transfer of ownershi p of substantial 1and areas to the State. The process for such transfer has not yet been establ i shed but coul d entail purchase and/or an exchange of other State selected lands with Nat i ve groups. The proposed locations for the Watana camp and village are on federal lands that have been selected by the State.Ultimate transfer of title to these lands will not be affected by the project. For more discussions on land stewardship,see Chapters 9.1.2 and 9.2.1 of Exhi bit Eo 4.2 -Land Management Based on avail ab 1e i nformat i on and agency i ntervi ews,it has been determined that little comprehensive management exists at present. Section 9.2.4 of Exhibit E describes existing land use management plans.Table £.9.5 summarizes the existing and proposed land use management activities in the project areas. E-9-36 ~--~"----_._.-._----------------~-,.,...-----------' The BLM has no proposals for management planning,other than the existing DenalijTiekel Planning Blocks. The Alaska Department of Natural Resources (DNR)has prepared a plann- i ng background report in cooper at i on with Matanusk a-Sus itna Borough (Mat-Su Borough),Kenai Peninsula Borough and the Alaska Department of Fish and Game,and Transportation and Public Facilities.The DNR is preparing a land use report that describes and categorizes potential land use in the southcentral region of Alaska.This document will be completed approximately May,1983.A land use plan will be completed by the DNR in 1986. Future agricultural land sales are proposed in the DNR Draft Land Use Plan for Public Lands in the Willow Sub-basin,1981,along with programs for protecting wildlife habitat and sportmen1s access. The Alaska Department of Fish and Game (ADF&G)has developed species- s pecifi c objectives for the regi on,but it has no 1and management authority.Other agenci es have prel i mi nary addressed 1and management concerns.The generat i on of hydroel ectri c power wi 11 become the predominant land use in the area,and the presence of the project will be an important factor when agenci es eventually develop comprehensi ve land management plans. The Matanuska-Susitna Borough has prepared a planning background report.The Mat-Su Borough wi 11 compl ete a draft comprehensi ve 1and use plan in November,1982. The Fairbanks Northstar Borough is preparing a Borough-wide,comprehen- sive 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 be 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 upper 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 adjacent to project lands.Furthermore,an increase in hunting,fishing,and general use of the project area is probable.These activities may require in- creased fish and wildlife management and may result in surface- disturbing activities. Specific controls may be required to protect resource value.Controls could include establishng acquisition limits for hunting and fishing, permitting a limited public entry,ORV management,and other land management. E-9-37 - - - - - Finalizing specific management plans and mitigation measures for trans- mission line right-of-way,access,recreational use,and residential accommodations,will proceed during the Phase II of the Susitna Hydro- electric Project.The Alaska Power Authority will work closely with the aforementioned development of land use plans.

Planning for the disposal of state lands that are immediately adjacent to the west side of the project area (north and south of Chulitna). Performing hydroelectric development feasibility studies. Borough has no lands in the project area.Project area does fall within the borough's boundaries and is part of the borough's Talkeetna Mountain Special Use District.Project area is a "mixed use"zone. Currently has designated the Susitna River to and including Devil Canyon as part of a biophysical area for the Coastal Zone Management Program. None;lands currently being trans- ferred to individual villages. Future management will be guided by Southcentral Planning Area Management Framework Plan and an easement management plan. State will select lands in project area not selected by the Natives. Management planning on these lands will not begin before 1983. Dependent upon outcome of feasibility studies. By Ordinance No.79-35 creating the Talkeetna Mountains Special Use District.the borough can exercise planning and zoning authority over private lands within its boundaries; will commence further activities when hydro studies are completed. Continuing CZM studies will determine any additional management direction. Management planning not yet underway.
