It identifies the desired patterns of land use over the next 20-25 years and gives the desired densities of residential development within the various neighborhoods that make up our community. The Plan also contains recom- mendations on the following subjects: environmental, transportation, energy, and parks-open space. These are the basic support systems for residential, commercial, and industrial growth. They are meant to be complemen- tary of the desired land use patterns, and should work to achieve the community's desired growth patterns. But most of all, the Plan is meant to be an expression of what the community desires regarding growth. It is an embod- iment of the values, concerns, and aspirations of what the citizens of Anchorage want over the next 20 years in terms of development. The Comprehensive Plan guides development but does not, by itself, actually control where and when growth shall and can occur. Other means are used to implement the Comprehensive Plan. Some of these methods are well known, and include zoning and the subdivision process. Other methods are sometimes used to control growth that are not as well know, however. These include such techniques as capital facility programming, growth management, and building codes. These tools can be organized into general categories depending on how directly they affect land development, whether they deal with the patterns of development or their timing; and if they involve the use of capital facilities to guide growth or deal with the regulations relating to land development. Page references relating the imple- mentation tools to the recommendations contained in this plan are included, to assist the reader. Direct Land Use Controls These controls include subdivision reviews and zoning. Subdivision involves the conversion of raw land into some form of land use such as housing. Under subdivi- sion regulations, the Municipality requires the dedica- tion of streets; the inclusion of water, sewer, and storm drainage lines; and the satisfactory layout and design of lots. This review may also require adequate on-site septic and water systems, and the reservation of land for scenic easements and open space reserves. The Comprehen- sive Plan expands the use of the subdivision power to include the review of the effects of development and to require such mitigation measures as may be appropriate (pp 65-66). Zoning regulates the use of land. It is specific to individ- ual properties and regulates the use of property, the height and bulk of structures, establishes yard and street setback requirements, and specifies population limits. It is that device which is normally associated with land use planning. The Comprehensive Plan is intended to guide future zoning. Because the Plan was developed around a lengthy planning process relating economic growth to the demand for land, and because the Assembly has endorsed this document as its basic guide to future development, future zonings are meant to generally coincide with the Plan's land use patterns and densities. However, the Plan is a guide to future rezonings; it does not actually establish the zoning pattern. The Plan des- cribes how future rezonings are to be interpreted rela- tive to the Plan (p. 75). The Plan, as applied to residential zonings, discourages rezonings from higher to lower density levels unless a clear neighborhood need exists (p. 75). It also recognizes that densities may be some- what higher than those designated in the Plan at major development nodes and around neighborh.ood shop- ping centers or along principal transit corridors (pp. 75-76). Finally, the Plan states that there is a need for more flexible approaches to development and that cer- tain of our current zoning devices need revision. These methods are described in the 'Residential, Short-Term Objectives' section (pp. 64-68). Controls Over Construction and Design Processes The previous controls deal with the general pattern of land uses and with the conversion of raw to developed land. They are meant to control the basic process of land development. Other controls exist to affect the design and construction process. These are oftentimes referred to as construction codes, design criteria, and administra- tive Municipal procedures. With the exception of buffer- ing and design criteria standards, these methods are not directly affected by this Plan, although they are designed to further its goals and purposes. Specifically, building codes are meant to ensure adequate, safe dwellings. This corresponds to the housing goal and its intent to provide satisfactory housing to all Municipal citizens. These tools are tied to the Plan in an indirect way. They relate to zoning and subdivision codes or to design criteria for public facilities that are, in turn, derived from the recommendations of this Plan. The reader is referred to the Anchorage Municipal Code, Title 21, for a fuller description of these ordinances and regulations. A dis- cussion of buffering and design standards is included on pp 64-65. Controls over the Timing of Development Comprehensive plans, like this one, are meant to express the desired development patterns of the community. Usually these patterns are representative of land uses and residential densities that should or ought to exist 20-25 years in the future. This is not to say that these patterns and densities are not appropriate to, nor desir- able for immediate time periods as well, for often they are. Nonetheless, contemporary planning theory has increasingly emphasized that if future, recommended patterns are to be acl;lieved, there must be a clear and definite process established to realize these patterns. The 'Land Guidance System' section describes just such a process (pp. 69-74).1t specifies areas for development, the general timing of development, and the types of tools to actually achieve the desired development pat- terns. This timing component (pp. 71-72) places heavy emphasis upon the use of major capital facilities, like water and sewer, to achieve the goal of properly timed growth. These facilities are financed and scheduled through the Municipal Capital Improvement Program. The Plan requires that the Program be consistent with this document's timing recommendations (p. 70). Finally the plan recommends the use of new design tools and zoning processes (p. 70) to better deal with the costs of housing development in environmentally sensitive areas-- of which Anchorage has many. ill Consistency of Infrastructure of Development with Plan The desired urban forms, as well as the regulatory and design tools designed to implement them, are ultimately dependent upon what is termed as 'infrastructure'--the systems of water, sewer, roads, parks, and similar urban amenities and essential services that are vital to urban life. These services must support the recommended land use patterns if the latter are to be achived. Specifically, they must be consistent with and reinforce these pat- terns. The major infrastructure systems are described at length in the Plan under the chapter called 'Functional Element' (pp. 7-49). The Environmental System, con- cerned with environmental protection and enhance- ment, examines these subsystems at length and includes sections on water quality, air quality, and coastal zone management. The Transportation System, consisting of major roads, transit, and alternative mode programs, is described in pp. 26-32. Finally, tlrie Parks and Open Space (pp 33-48) and Energy (pp. 49-54) Systems exam- ine the required open space improvements and energy conservation/ development programs necessary to pro- vide a high quality of urban life and satisfactory energy utilization. Each of the components is intended to be compatible with the others, and with overall land use patterns. Summary A plan does not, by itself, create the future. It points to a future and gives certain signposts and methods as to how the future may be achieved. For this future to be realized there must be commitment to the Plan but, perhaps to a larger degree, to the need to deal with potential future growth problems in the present. Prob- lems are difficult and oftentimes impossible to reverse once an unwanted condition or action has begun. There must be, if this Plan is to succeed as a guide to develop- ment, a commitment to a type of problem solving that is creative, constructive, and balances short-term gains with long-term goals and objectives. Each and all of the implementation techniques the Ml:micipality processes are not wholly satisfactory unless this attitude and approach is pursued in the daily activities of our Munici- pallife.lfthis approach is followed, our present activities will ultimately manifest themselves as an eventual urban form. This plan can help to achieve these growth objec- tives if this attitude exists and is practiced. iv D 0 0 D 0 0 0 0 0 0 0 0 D 0 0 0 0 0 0 0 D 0 nl u D 0 ' I 0 Page CHAPTER 1 -An overview of Anchorage's Comprehensive Plan 1.1 Introduction. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 1.2 Purpose and Scope ............................................. 2 1.3 Uses of the Plan . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 1.4 Plan Development Process. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 1.5 Organization of Plan . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 CHAPTER 2 -Functional Element 2.1 Introduction. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.2 Environmental Component ....................................... 7 2.3 Transportation Component ...................................... 26 2.4 Parks, Recreation, and Open Space Component .................... 33 2.5 Energy Component ............................................. 49 CHAPTER 3 -Urban Development: Patterns and Process 3.1 Urban Development: Patterns and Process ......................... 55 3.2 Land Use Element .............................................. 56 3.3 Land Guidance System .......................................... 69 CHAPTER 4 -Plan Implementation 4.1 Introduction. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 5 4.2 Land Use Implementation Mechanisms: Land Use Patterns ................................................... 75 4.3 Adoption of Certain Additional Elements as Part of the Comprehensive Development Plan ...................... 76 4.4 Urban Development Plan ........................................ 76 4.5 Relationship of Comprehensive Development Plan to Major Planning Programs and Activities ...................... 76 4.6 Procedural Land Use Implementation Mechanisms .................. 78 4. 7 Land Use Implementation Process Mechanisms . . . . . . . . . . . . . . . . . . . . . 79 4.8 Plan Review Process . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 79 TABLE OF CONTENTS Page Table of Tables 2-1 Goals, Policies, Objectives: Environmental Component .................... 18 2-2 Goals, Policies, Objectives: Transportation Component ................... 31 2-3 Standard for Parks by Classification and Population Ratio .................. 36 2-4 Goals, Policies, Objectives: Parks, Trails, and Open Space .................. 44 2-5 Goals, Policies, Objectives: Energy ..................................... 52 3-1 Goals, Policies, Objectives: Land Patterns ............................... 64 3-2 Goals, Policies, Objectives: Land Management Process . . . . . . . . . . . . . . . . . . . . 73 Table of Maps 2-1 Preservation Map ..................................................... 9 2-2 Conservation and Utilization Map . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 0 2-3 Transportation Plan Map .............................................. 29 2-4 Parks and Open Space Map ........................................... 47 3-1 Land Use Plan Map .................................................. 57 3-2 Residential Intensity Map ............................................. 59 3-3 Urban Phasing Strategy Map ........................................... 71 v vi u 0 0 0 0 0 0 D n 0 0 D D 0 n L L L' [ ~ 1.1 INTRODUCTION Rapid growth in Southcentral Alaska and especially in the Anchorage metrop o litan area has p l aced increas- ingly greater burdens upo n the enviro nmental, fiscal, and public fa c ility sys tems that support and guide urban development. This growth has a l so required l arge amounts of land within the Anchorage Bowl to accom- modate competing residential, industrial, and commer- cial land demands. Currently, 32,340 acres are deve- loped; of this amount, some 13,500 a cres are used f o r residential purposes, 1,300 acres for commercial, and 1,440 for i ndustrial. Considerable land remains within the Anchorage Bowl, i n c lu ding, under cu rrent zoning, some 13,900 acres of residential, 1,14 0 acres of commercial, and 2,400 acres of i ndustrial land . In addition, some 7,5 0 0 acres of land are zoned unrestricted but most likely will be avai lable for re sidential use i n the Potter and Littl e Rabbit Creek drainages in south Anchorage . It ca n be expected that increa sing d emograph ic change and economic growth o v er the next twenty years will place great demands upon the remaining land supply. Anchor- age wi ll be faced with the need to use wisely the last remaining land parc els while minimizing environmental and fiscal impacts. This basic iss ue of growth--its proper pattern, density, and quality--is the central theme of the Comprehensive Plan . The following desc riptions exami ne the current patterns of la nd devel o pment, the pressures placed upon the ava i lable la nd i n ventory from competing eco- nomic and social forces, and the rec ommended strate- gies to deal w i th these press ures. A compr ehensiv e plan is necessarily a represe ntation of the atti tudes and perceptions of the ways to deal with future growth at a par t i cular time.lt can be assumed that conditions, e v ents, and attitudes will change o ver t i me, which requires th e development of a method to deal with chan ge. This Plan includes such a component. It is also concerned w ith provid i ng methods to effectively respond to and guide the processes of development over time and space. CHAPTER ONE AN OVERVIEW OF ANCHORAGE'S COMPREHENSIVE PLAN 1.2 PURPO SE AND SCOP E The 1981 Comprehensive Devel opment Plan is i nte nded to serve as a pract ical guid e for community develop- ment. It is formulated around a series of key "functional" areas of urban planning concerned with the major pub- lic facili t ies and services desi gned to support urban develo pment. These se rvices a lso guide the location of urban deve lopment and appo rtion the density of t h at growth. Incl uded in t hese descriptions are goals, objec- tives, and policies which support the development of these facilities and provide direction to the manner in which they are to be organiz ed. Initially, these goals and objectives were a synthesis of the public participation process used in developi ng the 1976 Comprehensive Plan, but have since been augmented to incl ude re - sp o nse s to new c o nditio ns and even ts which have taken place d u ri ng the past fi ve years. The Plan also in c ludes implementation gu ideli nes to be appl ied in conjunction with the l and u se maps. The l atter allocate basic uses as appropriate to the n eeds of t he co mmunity. Methods to direct th is process over t i me ar e also identified. They p rovide the dimension of time to th e maps of land u ses . The Plan is necessari ly general, to be further defined by appropria tely detailed plans, by ordinances and other p o li cy tools applied by the Assembly and Pl annin g and Zoning Commission. The Comprehensive Pl an focus es upon the physical rel a- t ionshi ps and development patterns of the community. It is intended to deal with conditions and events expected o v er the next 20 years. This length o f time is the u sual limi t of demograph ic and economic forecasting, and corresponds to the t i me period used i n the design of most major pubtic faci lities. The Land u se and Residen - tial Intensity Maps ar e geared to a somewhat l onger time period, although the l and patterns are generally t h e r esu l t of land acreage allocations to t he design peri od (year 2000 ). These maps represent the preferred pat- tern of community devel opment. The Comprehensive Plan also focuses upon what is termed the "Anchorage Bowl". This is the area of major u rbanization extend i ng from t he military bases in the north, to the Ch u gach State Park in the east, to the Knik and Tu rnagain A rms of Cook Inl et i n the west, to the 2 Turnagain Arm and Chugach State Park i n the south . The Plan recomme ncations and data analyses are confi ne d to this a rea . The other urbani zing ar eas o f t he M u n icipa l- ity, including Ea gle River-C hugiak-Eklutna and the Turn- aga i n Arm, are covere d by separate compre hensive plans. This is not to indica te that the seve ra l comprehen- sive plans are mutually exc lu sive . The land and public faci l ity requirements, as wel l as t he p opul ation al loca- tions, are derived from demograph i c p roj ecti ons that treat each ar ea as part of an i ntegrated economic uni t w ithin Southcentral Alaska . 1.3 USES OF THE PLAN The adopted Comprehensive Plan is a publ ic declaration of the general policies which w ill gu i de but n ot b ind , the a c tions of the legis lative body. This declaration of policy is a refl e c tion of comm u nity goa ls as expressed by t h e community and approved b y t hei r e l ect ed representa- t ives. Some of the ben efits and purposes o f the Comprehen- sive Plan and the plan ning process are outlined as follows : • The Comprehensive Plan is designed to improve the physical, social, and economic environ ment of the community. • The Comprehe nsive Pl a n se rves as a sour ce of i n for- mati on to the ge n eral publ ic, as well as to government agencies having an impact upon physica l development decisions. • The Comprehensive Plan serves as a m eans o f coor- dination between the p rivate and public sectors, be- tween d i fferent government agencies, and between the legisl ative body and its t echn ical staff. • The Comp re h ensive Pla n serve s as the best es t imate of th e future--an esti mate t hat is gu ided by speci fic com- munit y goals. The plan re flects what is most l ik e ly t o happen if the policies and p rog rams i n the plan are followed. • The Comprehensive Plan se rves as a declaration of public p o licy re ga rding physical development and clearly states the objectives and actions that th e com- mu nity intends to pursue t o ac h ieve the r e c ommen- dations co ntained in the Plan . • The Com pre hensive Pla n foc uses atte n tion u pon the m ajor issue s confronti ng the comm un ity, and aids in resolvi ng these thr o u gh a d i scussio n of the conse- quences of alternative courses of action . The Comprehensive Plan and its attending planning pro- cess are intended to be instru mental in both guiding and influencing urban development. It is a method whi ch he l ps to ensu re t hat community resourc es w i ll be used i n the most effi cient ma nn er practicabl e to rea c hi ng com- munity goals . In addit ion, it can serve as a vehicl e for representing, to the publi c and p r ivate sectors, the likely future of the c ommun ity and the means to b e used to achieve that fu ture. 1.4 PLAN DEVELOPMENT PROCESS Th e process for revi si ng the Anch o rage Compreh e n sive Development Plan focu sed about six major rese arch areas: • Defin ing planning alternatives, • Analyzing the land mana gem ent alternatives necessary t o implement particular l and use densities and patterns, • Research ing e fforts relating to land demand and su p p ly, • Developi ng poli cies and objectives re lati ng to physi cal growth and urban form, • Devel oping and syn thesizing major f unc tional planning activities, and • Formulating major land u se alternatives. It i s i mporta nt t o recogn i ze that this p la nning effort is bu ilt upon the technical and ci t i ze n involveme nt efforts i nvolved in preparing the 1976 Compr ehensive Deve l- opment Plan . Many of t h e goa ls and objectives deve- loped durin g th e p u blic participation p rocess i n 1976 are retain ed i n this Plan , and form much of the basis for the Plan 's recommendations in its functional and la n d use sections . The more recent planning activities focus on an integration between la nd use and fun ctional planning, the establishment of a mana gem ent process to d irect growth patter ns, and changes t o the Land Use a nd Res i- dential Intensi t y Maps. n ,.... L LJ L L L .._ The research process involved in the revision of the Comprehensive Plan can best be described in terms of a sequence that focused on a broad development al ter- natives a n d then attempted to make these patterns more specific and operational. This process also tried to incor porate functional with developmen tal planning and to analyze the various constraints and opportunities for urban growth through a se ries of economic, demo- graphic, and environmental studies. 1.4.1 Alternative Land Use Study The revision of the Comprehensive Devel opment Plan began with an analysis of alternative growth patterns. The Alternative Land Use Study identified a series of alternative growth patterns and densities, and assessed the varying impacts of these forms. Thes e impacts were measured in terms of social, economic, land use, and environmental indi cators . Incl u ded among the ap- proaches to urban form and growth were alternatives that: • Concentrated urban growth in a more p u rposeful way throu gh a pattern of extensive in-f i lling, • Allowed metropolitan growth to cont inue to disperse, allowing a low-density metropolitan form to emerge, • Fostered a gradual in-filling of urban lands, to achieve a moderate concentration of urban development, • Dispersed urban growth to the Eagle River-Ek l utna- Chugiak and the Matanuska-Susitna Borough areas, and • Decreased urban growth, putting a "lid" on future community expansion. Of the alternatives, that i nvolving a progressive infil ling of urban lands tended to be most cost-effective and pro- duced the fewest environmental and social disruptions. 1.4.2 MUHICIPAL LAHD MAHAGEMEHT SYSTEM Urban growth occu rs over space and time. The 1976 Comprehen sive Plan focused on the questi on of spatial re lationsh ips at a specifi c time in the f uture. The Munici- pal Land Management System study was designed to bridge the gap between the urban patterns we wish to create, and our desi re and ability to use the manage- ment tools required to attain these forms . It analyzed the types of co ntrols used to manage land and related these to the alternate urban forms giv en in the A lternative Lan d Use Study. Different land management techniques are required to realize certain patterns o f l and uses. Management controls were se l ected for development that implemented a moderate in-fil ling patt ern . These controls involved the further strengthening of the cu r- rent zoning and subdivision regu lations; the devel- opment of a systematic strategy f or the siz i ng and instal- lation of urban services, especially sewerage; and the establi shment of progr ams involvin g land ban kin g and capital facility programmi ng. The most i mport ant o f these strategi es are related to the timing and phasing of capital facilities in south Anchorage . Because o f their large influ- ence over urban development, capital pro jec ts were found to be most effective o f the va rious strategi es in guidin g the timing and density o f growth. 1.4.3 RESEARCH AHD AHALYSIS: LAHD IHVEHTORY, HOUSIHG, ECOHOMIC PATTERHS The previous alternative testing and land management analyses were designed to frame the scope and focus the direction of the Co mprehensive Plan revis i on. Th ey were intended to establi sh the general pattern and density o f urban growth to the year 2000 and to indicate the t ypes and mix of controls necessary to ac hi eve those patterns. The analyses that fol lowed focu sed d i rectly o n the revis i on of the Comprehensive Plan. The re- vised Comprehensive Plan in- cludes three major sections-- goals and objective s, major functional systems to support urban devel opment, and the desired patterns of urban growth. The basic research studies in- cluded the following: • Deteriorated Housing Su rvey • Housing, Land Use, and Zon- ing Inventory • Housing Market Model • AMATS Metropolitan Employment Surve y • Anchorage Coastal Atlas • Land Demand Pr ojections : Commerci al & Industrial • Lan d Demand Projections: Reside ntia l These analyses inventori ed t he b asic constituents of development, as sessed the pro bable future causes of and influences upon growth, and p roj ected needs for t he va ri ous land types and densities. In particular, the Deteriorated Housi ng Survey identifi ed the main areas of substandard, deteri orati ng, a nd d il apidated housing. If centrally l o cated and adj acent to major employment centers, such areas commonly experience redevelop- ment to higher densities. Several such areas exist near the downtown in Fairview and Mountain View. This con- clus i on is important due to t he negligible amount of developable land remaini ng i n the Anchorage Bowl and bec ause of the co mmunity's policy o f ensu ring the effec- tive use of public facilities. The Housing, Land Use, and Zoning I nventory served to ident ify the d istribution and amount o f the a rea's hous ing stock (single-and mul t i- 3 "' c.l ~ 10 c:: <( .... 0 Ill c. ~ 4 ---~ "' c > "' :c.

These data were separat ed into small geograp hic areas and were organized accord- ing to acreage amounts for undeveloped and deve- loped land. These data wer e essential in determining where growth has occurred and how it was arranged, and where future growth might occur--on the basis of the vacant, developable l and supply. The AMATS Met- ropolitan Employment Survey identifi ed the amou n t of empl oyment by place of employment i n the Anchorage Bowl. To gether, these reports described current eco- nomic, population, and land conditions within the Bowl. Environmental data were mapped at a common 1:25,000 scale in the Anchorage Coastal Resource Atlas. This document gives a detailed inventory of physica l, biologi- cal and engineering data, to complement the socioeco- nomic information provided by the other studies. The inventory analyses were complemented by studies of future fa cili ty need5 and land patterns. The Housing Market Model analyzed the various trends affecting cur- rent and future housing conditions. It also projected the amount and distribution of single-and multi-family hou s- ing by small geograph ic areas. Th ese forecasts were e ssen tial to later evaluations of land needs and to the development of housing redevel opment st rategies in deteriorating areas. A final analysis, Commercial-In dustrial Employment and Acreage Allocations, speci fied f uture popu lation, dwel- l ing unit, and employment amounts. These data were then translated into acreage demand re quirements, which formed much of the basis (along with the residen- tial housing analyses), for the land use designations con- tained herein . 1.4.4 FUNCTIONAL PLAN DEVELOPMENT The revised Comprehensive Plan includes sections on the main public facility and environmental systems. Pub- lic facilities support and infl uence the pattern and den- sity of growth, and mainta i n c ultu ral and social systems . The environmental sys tems act as constraints to growth as well as providing recreational, aes- t hetic, health, and open space values and opportunities. A ser- ies o f studies, p repared si nce the period of in itia l plan de- vel opment i n 1976, form the basis for these functional, or infrastructural, elements. The Environmental Component was based largel y upon th e fo l- lowing studies: • Water Quality Management Plan • Air Quality Plan (draft) • Coasta l Zone Management Pl an • We tlands Management Pla n (draft) The Transporta tion Compon- ent was derived from the var- ious analyses prepared by the Anchorage Metropolitan Area Transportation Study, and largely from th e fol- lowing: • Long Range Eleme nt • Tra ns p o rtation Sys te ms Management Element • Tra nsi t Development Program • Light Rail Feasibility Study The Parks and Recreation Element was large ly based upon the foll owi ng analyses : • Areawide Parks and Open Space Plan (draft) • Areawide Trail s Plan • Sub-area Parks Plans (various ) The Energy Component was based upon the following technica l reports : • Energy Crisis Conti ngency Pl an • Energy Eleme nt, Comprehensive Pl a n, Technical Report Each of these studies provided documentation as to the needs o f the various components, and are to be dis- c ussed in mo re detai l in Chapter Two. 1.4.5 POLICY FO RMULATION PROCESS The plan development process also i nvolved the formu- l ation of community goals, objectives, and policies . This analysis identified goal s, objec tives, and pol icies for a variet y of functional, or in fras tru ctur e, areas. Infrast ruc- ture is defined as t h ose systems f o rming the bas1c foun- dation support mechanisms of the u rban commun ity. Goals and objec tives were developed for the following elements: • Land Use • Envi ronme nt • Tra n sportation • Ene rgy • Parks , Rec reation, Open Space These goals were derived from literature reviews, the previous Comprehensive Plan, and from already adop- ted fu nctional p lans and studies of the Municipality. The impo rt ance of th e Pol icy /Goal Component is t o set the basic di re c tion for commun ity acti viti es , i ndicate t hose policies and programs necessary to ach i eve those activi- ties, and esta blish an interrelationsh ip among the various socioecono mic for ces and systems that affect the com- m unity's physical deve lopment and form. 5 1.5 ORGANIZATION OF PLAN This report is separated into four major sections : • Introduction • Functional Plan Components • Land Use-Land Management Element • Plan Implementation The Functi onal compone nt describes the approach to be used by the Municipality in the provision of important public services. It also sets Muni cipal policy regarding economic development and energy management. The se components are essentia l to the creation of the urban forms and densities ex pressed in the Land Use Plan . The components are al so interrelated, both to each other and to the desi red urban form. Th e Land Use-Land Management depicts the desired urban forms and d ensities, and indicates those manage- ment tools necessary to focus growth over time to achieve desired urban patterns. This component is, i n turn, based upon the Plan's functional component and works to drive t he i mplementation component. The Implementation Element identities those tools and methods necessary to carry out the recommendations of the Plan. Without a strong commitment to the mecha- nisms required to achieve desired urban forms and infrastructure syst e ms, community goals cannot be fully realized. 6 ~ \ . -.J 2.1 INTRODUCTION Th e functional element of t he Comprehensive Pla n des- cribes those major components of the planning p rocess that support and affect physical devel opment. These systems interact, influencing each other and, ultimately, the patterns of land uses and the qual ity of comm u nity life. Certain of these systems are strong determinants of growth while others act to constrain the amount and location of growth . Th e functional syste ms described he rein i nclude: • Environment • Transpor tation • Parks and Open Space • Energy Most of these systems are examined at length in separate studies and reports p r epared by the Municipality. They ar e summa r ized in the Co mpre hensive Pl an to p rovide an integration between l and use patterns and these components, and between the variou s systems them- selves. Detailed analyses of these systems are contained in the reports and st u dies from which they are derived. 2 .2 ENVIRONMENTAL COMPONENT The environmental component consists of three sub- ele ments: coasta l zone, water q u ality, and air quality ma na gement. The coasta l zone program addresses t he effective management of the nearshore area and the a reas directly affected by or affecting this area. The air and water q u al ity management p r ograms are, however, areawide in scope within the Anchorage Bowl. Different strategy areas and environmental processes are also encompassed by the various programs. The coastal zone management program is concerned with al l of the major p rocesses affecting the n earshore area, including: • su rface waters • wetlands • marshes, tidal f lats, and floodplain s • hazar dous land • anadromous streams • marginal land In co n trast, the other programs are structured around t h e u se of con trol strategies intended to improve a ir and water q u ality. Coas t al Zone Management is, t h en, co n- siderabl y broad er in scope than the oth er p rograms in ter ms of the types of land and envi ronmental p r ocesses affected by its ma n agement controls. Coastal manage- ment i ncorporates natural re source management c on- cerns into the urban p l anning process. Each of the environmental programs attempts to reflect and impleme nt a bal anced use phil osophy between devel o p me nt an d envi ronmental protection. This ap- proac h r ecogn i zes the t rade-off i nh erent to all environ- men t p rogra ms. It at tempts to maintain and en hance vital environmen tal processes whi l e a l lowing residential growth and economic development to conti nue. Envir- onmen t al resources, ec onomic productivity, and live- ability are interdependent. Economic activities use en- vironmental resources, and are maintained by the envi - ronmental resources they are dependent upon. Live- abili ty, in t urn, is deter mined by the i ntangible values of resources, b oth n atural and socia l. This interdepen- den cy is l imit ed by the fragil ity and fi ni te number and type of envir onmental r esour ces. In o r der t o main t ain both econ omi c and environmenta l resourc es , c areful consideration must be giv en to achieving a proper bal- ance between the competing demands of growth, gen- erated by economic expansion, and of preservati on, to maintain the sensi tive character of ecosystems. 2.2.1 COASTAL ZONE MANAGEMENT Description of Program Coastal Zone Management pla nning is a result o f both the Federal Coastal Zone Management Act o f 1972 and the A l aska Coastal Management Act o f 1977 . Both acts require that states use the nation's coasta l r esources and promote their wise and balanced use. The reassert ion of the rightful responsibilities of local and state govern- ments i n r egul ating the use a nd deve lopment of their coastal resources i s a maj or aspect of both acts. The coastal zone ma nagement program must be con- sistent w i th Fede ra l and State law and regul ations. Such programs mu st inclu de, but are not limited t o, the foll owing: • a description of the land and water uses and activiti es subject to the district program, and a description of geop hysica l hazard a reas, recrea t ion, t ransportation CHA PT ER TWO FUNCT I ONAL ELEMEN1' 7 and utilitie s, energy facilities, and water-re lated activi- t ies. • a description of the u ses and activities that will be consi dered proper and im proper in the coastal area . • a statement of the policies that will be applied to l and and water u ses and activities subject to the district program. Issues The basic issue of coastal zone planning is to effectively manage c oastal resources, while balancing the compet- ing claims of environmental protection and urban growth . Th is is a particularly difficult task, given the prox- imity of the coastal zone to major areas of economic and urban expansion. Municipal growth is expected to rea c h over 338,000 inhabitants in the next twenty years, and the number of employees sh ould increase from 65,000 to a over 150,000 over the same time period. Confli ct s between various l and u ses are sure to arise . The thru st of Anchora ge's coast al zone program is to devise and im plement a rational process for resol ving these con- flicts . Th is process sho uld maintai n the del icate bal ance among the economic, environmental, and social forces that maintain human well-being; and it must be flexible enough to respond to new info rmation and cha nging perceptions of human needs. The resolution o f this issue, in the Coastal Zone Manage- ment (CZM ) Plan, occurs th r o ugh a process which ident i- f ies the sub-units of the t otal landscape accordi ng to sui tability of use . Thi s process of land use suitability anal- ys is makes it possible to i dentify dominant and subordi- nate units of the landscape based upon a biophysical - cultural del i neation of the coasta l area. In the Coastal Zone Management Plan , the concept of geog ra - phic seg me ntation is used. This involves a division of the coast into different lan dscape resource units, each represe n ting a different type o f environment, and each exhibitin g its own un i que charact eristics. Th e terms u sed for the several la nd use suitability environments are: Preservat ion, Cooservation, and Utilization. Preservation Environment: This unit consists of geogra- p h ic areas characterized by the presence of environ- mental and/or cu ltural features considered val uable in their undisturbed or o ri ginal co ndition, and which are 8 relatively intoler ant of intensive human u se . Such areas sho uld be essentially free from development, or be c ap- able of being res tored t o their natural co nd i t ion, and they should be large enou gh to protect the va lu e of the resource . The emphasis in this c la ssification is on preser- vation or restoration c•f natural syste ms, and on the prevention or regulation of use s and activities which would degrade or destroy the natural environment. See Map 2-t. Conservation E nvironm•~nt: Th is area consists of those l and and water ar eas having certain natural or insti tu- tional use limitations which requi re protecti on prior to their development. The purpose of t his desig nation i s to protect areas for environmenta ll y related purposes such as pa rks, food protection, and forestry management. It does not intend t hat the natural environment be main- tained in a pure state; r ather, that all activities and u ses be ca rri ed o ut to prod uce min i ma l adverse impacts. Th e key factor in this classification is the ma nagement of uses and activities to maintain the natural quality of the site. See Map 2-2.

This growth has als o required l ar ge amounts of land within the Anc horage Bowl to accom- modate competing res i dential, industrial , and commer- cial land demands. Currently, 32,340 acres are deve- loped; of this am o unt, some 13,500 a cre s ar e use d f o r residential purposes, 1,300 a cres for commercial, and 1,440 for industria l. Co nsiderable land remain s withi n the Anchorage Bowl, inclu ding, u nder cu rrent zoning, some 13,900 acres of residential, 1,140 acres of commer c ial, and 2,400 acres of industrial land . In addition, some 7,5 00 acres of land are zoned unrestricted but most likely will be available for re sidential use in the Potter and Little Ra b b it Creek d rainages in so uth Anchorage . It can be expected that increasing d emograph ic change and eco nomic growth over t h e ne xt twent y y ears will p l ace gr eat demands upon the remaining land supply. Anc hor- age wi ll be face d with the n eed to use wisely the l ast remaining l and parcel s while minimizi ng e nvi ronmental and fis cal impacts. Th is basic iss ue of growth--its proper pattern, de nsi ty, and quali t y--is t he central the me of the Comprehensive Pl an. The following descriptions examine the current patterns of l and development, the pressures placed upon the available land i n ventory from competing eco- n omi c and social forces, and the recommended strate- gies to deal wi th these pressures. A co mprehensive plan is necessarily a re presentati on o f the atti tudes and perceptions of the ways to deal with future growth at a particular ti m e . It can be assumed that cond itions, events, and attitudes will change o ver t i me, which requires th e development of a method t o deal w ith change. This Plan inc ludes such a component. It is also concerned with provid ing methods to effectively respond to and guide t h e processes of development over time an d space . CHAPTER ONE AN OVERVIEW OF ANCHORAGE'S COMPREHENSIVE PLAN 1 1.2 PURPOSE AHD SCOPE The 1981 Comprehensive Development Plan is intended to serve as a practic al guide for community develop- ment. It is f orm ulated around a series of key "functional" areas of urban planning concerned with the major pub- lic fa cilities and services desi gned t o support urban development. These se rvices also guide the location of urban development and apportion the density of that growth . Included i·n these descriptions are goals, objec- tives, and policies which support the development of these facilities and provide direction to the manner in which they are to be organized . In itially, these goals and objectives were a synthesis of the publ ic participation process used in developing the 1976 Comprehensive Plan, but have since been augmented t o include re- spo nses to new conditions and events which ha ve taken place during the past five years . The Plan also inc ludes implementation guideli nes to be applied i n conj unc tion with the land use maps. The latter allocate basic uses as appropriate to the needs of the comm unity. Methods t o direct this process over time are also identified. They provide the dimension of time to the maps of land uses . The Plan is necessarily general, to be further defined by appropriately detailed plans, by ordinances and other policy tools applied by the Assembly and Planning and Zoning Commission. The Comprehensive Plan focuses upon the physical rela - tionships and development patterns of the community. It is in tended to deal with condition s and events expected over the next 20 years. This length of time is the usual limit o f demographic and economic forecasting, and corresponds to t he time period u se d in the design of most major public fa cil ities. The Land Use and Re siden- tial Intensity Maps are geared to a so mewhat longer time period, although t h e lan d pattern s are generally the result of land acreage allocations to t he design period (year 2000). These maps represent the preferred pat- tern of community d evel opment. The Comprehensive Plan also focuses upon what is termed the "Anchorage Bowl". This is the area of major urbanization extending from the military bases in the north, to the Chugach State Park in the east, to the Knik and Turnagain Arms of Cook Inlet in the west, to the 2 Turna gain Arm and Chugach State Park in the south . The Plan recommencations and data analyses are con fined to thi s area . The other urbanizing areas of the Municipal- ity, including Eag l e River-C hugiak-Eklutna and the Turn- again Arm, are covered by separate comprehensive plans . This is not to i ndicate that the several comprehe n - sive plans are mutually exclusive. The land and public fa cil ity r e quirem ents, as well as the popul ation alloca- tions, are derived from demographic proje ctions that treat each area as part of an integrated economic unit within Southcentral A l aska . 1.3 USES OF THE PLAH The adopted Comprehensive Plan is a public declarati on of the general policies wh ich will gu ide but not bind, the actions of the legislative body. This declaration of policy is a reflection of com mun ity goal s as expresse d by the community and approved by thei r elected representa- tives. Some of the benefits and purposes of the Comprehen- sive Plan and the planning process are outlined as follows: • The Comprehensive Pla n is designed to i mprove the physical, social, and economic environment of the community. • The Compreh e n sive Plan serve s as a source of infor- mation to the general public, as well as to government agen cies h aving an i mpact upon physical dev elopment decisions. • The Comprehensive Plan serves as a means of coor- d ination between the private and public sectors, be- tween different government agencies, and between the legi slative body and its technical staff. • The Comprehensive Pl an serves as the best estimate of the future--an estimate that is guided by specific com- munity goals. The plan reflects what is most l ikely to happen if the pol icies and programs in the plan are f ollowed. • The Comprehensive Pla n serves as a declaration of public policy regarding physi cal devel opment and clearl y states the objectives and actions that the com- munity intends to pursue to achieve the recommen- dations contained in the Plan . • The Comprehensive Plan focuses attention upon the maJOr issues confronting the communi t y, and aids in resolving these through a discuss ion of the conse- quences of alternative courses of action. The Comprehensive Plan and its attending p lan n ing pro- cess are in tended t o be instrum ental in both guiding and influencing urban development. It is a method which hel ps to ensure that community resou rces wi ll be used in the most efficient manner practicable to reaching com- munity goal s. In addition, it can serve as a vehicle for representing, to the public and private sectors, the likely fu ture of the community and the means to be used to achieve that future. 1.4 PLAH DEVELOPMENT PROCESS The process for revisi ng the Anchorage Comprehensive Development Plan f o cused about six major research areas: • Defining planning alternatives, • Ana lyzing the land management alternatives necessary to implement particular land use densities and patterns, • Researching efforts relating to land demand and supply, • Developing policies and objectives relating to physical growth and urban form, • Developing and synthesizing major functional planning activi t ies, and • Formulating major land use alternatives. It is important to recognize that this planning effort is b uilt upon the techni ca l and c iti zen involvement efforts invo lved in preparing the 1976 Comprehensive Devel- opment Plan . Many of the goals and objectives deve- loped during the public participation process in 1976 are retained in this Plan, and form much of the basis f or the Plan 's recommendations in its functional and land use sections. The more re cent planning activities focus o n an integration between land us e and functional planning, the establishment of a management process to direct growth patterns, and changes to the Lan d Use and Res i- dential Intensity Maps. - u [ The research process involved i n the rev1s 1on of the Comprehensive Plan can best be described in terms of a sequence that focused on a broad development alter- natives and then attempted to make these patterns more specifi c and operati onal. This process also tried to incorporate functi onal with developmental planning and to ana lyze the v ario us constraints and opportunities for urban growth through a series of economic, demo- graphic, and environmental studies. 1.4.1 Al ternative Land Use Study The revi sion of the Comprehensive Development Plan began w ith an analysis of alternative growth patterns. The Alternative Land Use St udy identified a se r ies of alternative growth patterns and densities, and assessed the varyi ng impacts of these forms. These impact s were measured in terms o f social, economic, l and use, and env ironmental i ndicators. Included among the ap- proaches to ur ban form and growt h wer e alternatives that: • Concentrated urba n growth in a more purposeful way through a pattern of extensive in-fi l ling, • Allowed metropolitan growth to continue to disperse, allowing a l ow-density metropolitan form to emerge, • Fostered a gradu al in-fi lli ng of urban lands, to achieve a moderate co ncentration of urban development, • Dispersed urban growth to the Eagle River-Ek lutna- Chug i ak an d the Matanuska-Susi tna Borough areas, and • Decr eased urban growth, putti ng a "lid " on f ut ure communi ty e xpansio n. Of the alternatives, that i nvolving a progressive infi ll ing of urban l ands tended to be most cost-e ffective and pro- d uced the fewest environmental and social disruptions. 1.4.2 MUNICIPAL LAND MANAGEMENT SYSTEM Urban growth occurs over space and time. The 1976 Comprehensive Pla n focused o n the question of spatial relationsh ips at a specific time in the future. The Munici- pal Land Management System study was designed to bri dge the gap b etween the urban patterns we wish to create, and our desire and abi lity to use the manage- ment tools required to attain these forms. It analyzed the types of controls u sed to manage land and related these to the alternate urban forms give n in the Alternative Land Use Study. Different land management techniques are required to realize c ertain patterns o f land uses . Management co ntrols were select ed for development t h at implemented a moderate i n-f ill ing pattern. These controls invol ved the fu rther strengthen i ng of the cur- re nt zoning and subdi vision reg ulations; the devel- opment of a systematic strategy for the si zing and instal- lation of urban services, especial ly sewerage; and the estab l ish ment of programs i nvolvi ng land ba nking and capital facility programming. The most important of these strategi es are related to t h e timing and phasi ng of capital facil i t i es i n south Anchorage . Because of th eir large influ- ence over urban development, ca p ital projec t s were fou nd to be most effective of the va r iou s strategi es in guidi ng the timing and density of growth. 1.4.3 RESEARCH AND ANALYSIS : LAND INVENTORY, HOUSING, ECONOMIC PATTERNS The previous alternative testing and land management analyses were designed to frame t he scope and f ocus th e direction of the Comprehensive Plan revision . They were intended to establ ish the general pattern and density of urban gr owth to the year 2000 and to indicate the types and mix of co ntrols n ecessary to ac hieve th ose patterns. Th e analyses that followed focused directly on the revision of the Comprehensive Plan . The re - v ised Comprehensive Plan i n - c ludes three major sections-- goal s and objectives, maj or functional systems to support u rban development, and the desire d patterns of urban growth. Th e b a sic research studies in- c luded the following: • Deteriorated Housing Survey • Housing, Land Use, and Zon- ing Inventory • Ho usin g Market Model • AMATS Metropolitan Employ ment Survey • Anchorage Coasta l Atlas • Land Dem and Projection s: Co mmercial & Industria l • Land Demand Projections: Re sidential These analyses inventori ed the basi c c o nstituents of development, assessed t he probable future causes of and influences upon gr owth, and projected needs for the variou s la nd types and densities . In partic ular, the Deteriorated Housin g Survey identi fied the main areas of substandard, d e teriorating, and d il apidated housi ng. If c e ntrally lo ca ted and adjacent t o maj or empl o y ment centers, such areas c ommonly experience redevelop- ment to higher densities. Several such areas exist n ea r the downtown in Fairview and Mountai n View. This con- clusion i s important d u e to the negligible amount of d e v elopable land remaining in the Anc horage Bowl an d because of the c ommunity's policy of ensuring the effec- tive use of pu b lic facilities. The Housing, Land Use, and Zoning Inventory served to i dentify the distribution an d amount of the area's housing stock (s ingle-an d mu lti- 3 "' " ~ 10 c: < .... 0 " a. ~ 4 "' ~ ., c <( ...._ .c: u :;; 1)t .., IX ..... ~ .., c > .., ·n E u"' .., "' ·~.., 0 "' ~ "' 0..<( Alternative Land Use Study t Municipal Land Management System Deteriorated Housing Survey Housing Mar1<et Model Metropolitan Employment Survey Anchorage Coastal Atlas PLAN DEVELOPMENT PROCESS : LAND USE COMPONENT STUDY ACTIVITY Land Demand ~ Proj ections I-- Residentia l Land Demand Projec ti ons ~ Commercial & !- In dustrial ~ ~ Al ternative Lan d Use ~ Patterns Dra ft Plan Function To define major development alter- natives To identify methods t o gu1de growth To iden tify pot e n tial redevelop- me n t area s To i denti fy h o u si ng conditions and trends To 1dent1fy employment trends To 1dent1fy environmental con- ,..... straints ,_ To specify probable are as of resi-n dentia l development To specify probable areas of com- mercial-industr ia l growth To i dentify specific developmental alternatives [ LJ fam ily, mobile home, and dupl ex ), la n d us e pat terns (organi ze d accordi ng t o reside ntial, commercial, indu s- trial, and public l ands), and zon i ng patt erns (a rranged by p rin c iple zoning categories). Th ese data were sepa r at ed into sma l l geographi c areas and were organized accord- ing to acreage amounts for undeveloped and deve- l oped l and. These d ata were essential in det ermini ng w h ere growth has occurred and how it was arra n ged, and where future growth might occur--on the basis of the vaca nt, developable land supply. The AMATS Met- ropolitan Employment Survey identified t h e amount of employment by place of employment in the Anchorage Bowl. Together, these reports described current eco- nom ic, population, and land conditions within the Bowl. Environmental data were ma p ped at a common 1:25,000 scale in the Anchora ge Coastal Resource Atlas. This document give s a detailed inve ntory of physical, b iologi- cal and engin eering data, to complement the socioeco- nomic i nformation provided by the other studies. The in ventory an alyses were complemented by studies of future facility needs and la n d pattern s. The Housing Market Model analyzed the various t rends affecting cur- rent an d futu re hou sing co nd i t ions. It also projected the amount and distributi on of sing le-and mu lt i-family hous- i ng by sma l l geographi c ar eas. Th ese forecasts were essent ia l to l ater eva luations of land needs and t o the devel opment of housing r edevelopment strategi es in deteriorati ng areas. A fi n al analysi s, Commercial -Industrial Employment and Acreage Allocations, specified fu ture populatio n, dwel- ling unit, and employment amounts. Th ese data were then translated i nto acreage demand requi rements, which formed much of the basis (along with the res i den- tial housing analyses ), for the land use designation s con- tained herein. 1.4.4 FUNCTIONAL PLAN DEVELOPMENT The revised Comprehensive f>l an i ncludes secti ons on the main p u bl ic faci lity and environmental systems . Pub- li c fac i lities support and influence t h e pattern and den- si ty of growth, and ma intain cu ltural and social systems . The environmental syste ms act as constraint s to growth as well as providing r ecreational, aes- thetic, health, and open space va lues and opportunities. A se r- ies of studies, prepared si n ce the per iod of i n itial p lan de- ve l opment i n 197 6, form the basis for these funct ional , or infrastructur al , elements. The Environmental Component was based largely upon the fol- l owing stud ies : • Water Quali ty Ma nag ement Plan • Air Quality Plan (oraft) • Coas t al Zone Management Plan • Wetlands Management Plan (draft ) The Transportatio n Compon- ent was derived from t he var- iou s analyses p repared by the Anchorage Metropolit an Area Tran spo rtati on Study, and largely from the fol- lowing : • Long Range Element • Transportation Syst ems Man agemen t Element • Transit De velopment Program • Light Rail Feasib i lity Study The Parks and Recreation Element was largely based upon the foll owing analyses : • Areawide Parks and Open Space Pl an (draft ) • Areawide Trails Plan • Sub-ar ea Parks Plans (various) The Energy Component was based upon t he foll o wing tec hnical repo rts: • Energy Crisi s Contingency Pla n • Energy Element, Comprehensive Plan, Technical Report Ea c h of these studies provi ded d ocumentation as to the needs of the va ri ous components, and are to be dis- cussed in more detail in Chapte r Two . 1.4 .5 POLICY FORMULATION PROCESS The p la n develop ment process al so invo lved the formu- lation o f community goals, objectives, and polic1es. This analysis identi fied goals, objec t ives , and policies fo r a variety of fun c t ional , or infrastructure, areas . Infrastruc- t u re is defined a s those systems forming the bas i c foun- dation support mechan ism s of the urban community. Goa ls and o bjec ti ves w ere developed f o r t he following elements: • Land Use • Environment • Transportation • Energy • Park s, Re c reation, Open Space The se goals w ere derived from literature revi ews, the previo us Comprehensive Plan, and from already adop- t ed funct iona l pla n s and studies of the Municipality. Th e importance of the Po licy/Goal Component is to se t t he basic direc tion for community activi ties, i ndicate those p olic ies and p r ogra ms ne c ess ary to ac hieve those activi- ties, and establish a n interr elationship among the various socioeco n o mic forc es and syste ms that affect the com- m unity's physical development and form. 5 1.5 ORGANIZATION OF PLAN This report is separated into four major sections: • Introduction • Functional Plan Components • Land Use-Land Management Element • Plan Implementation The Functional compone nt describes the approach to be used by the Municipality in the provision of important public services. It also sets Municipal policy regarding economic development and energy management. The se components are essentia l to the creation of the urban forms and densities expressed in the Land Use Plan . The components are also interrelated, both to each other and to the desi red urban form. The Land Use-land Management depicts the desired urban forms and densities, and indicates those manag e- ment tools necessary to focus growth over time to achieve desired urban patterns. Th is component is, i n turn, based upon the Plan 's functional component and works to drive the implementation component. The Implementation Element identifies those tools and methods necessary to carry out the recommendations of the Plan . Without a strong commitment to the mecha- ni sms requi red t o achieve desired urban forms and infrastructure systems, community goals cannot be fully realized. 6 1 n ,..., ,..., [ 2.1 INTRODUCTION The functional element of t he Comprehensive Plan des- cribes those major compon ents of the planning process that support and affect physical development. These sys tems interact, influencing each other and, ulti mately, the patterns of land uses and the quality of community life. Certain of these systems are st ro ng determinants of growth while others act to constrain the amount and location of growth. The functional sys tems described herein include: • En viro nment • Tran sportation • Parks and Open Space • Energy Most of these systems are examined at le ngth in separate studies and reports prepared by the Munic ipal ity. They are summarized in the Comprehensive Plan to provide an integration between land use patterns and these components, and between the various systems them· selves . Detailed analyses of these systems are contained in the reports and studies from which they are derived . 2 .2 ENVIRONMENTAL COMPONENT The environmental component consists of three sub· elements: coastal zone, water quality, and air quality management. The coastal zone program addresses the effective management of the nearshore area and the areas d irectly affected by o r affecting this area. The air and water qual ity management programs are, however, area wide in sco pe within the Anchorage Bowl. Di fferent strategy areas and environmental processes are also encompassed by the various programs. The coastal zone management program is concerne d with all o f the major processes affecting the nearshore area, including: • surface waters • wetlands • marshes, t idal fl ats, and floodplai ns • hazardous l and • anadromous streams • marginal land In contrast, the other programs are structured around the use of control strategies i ntended to improve air and water quality. Coastal Zo ne Management is, then, con· siderably broader in scope than the other programs in terms of the types of la nd and environmental processes affected by its management controls. Coastal ma nage· ment incorporates natural resource management con· cerns into the u rban planning process. Each of the environmental programs attempts to reflect and implement a balanced use philosophy between development and environmental protection. Thi s ap· proach recognizes the trade-off inherent to all environ· m e nt programs. It attempts to maintain and enhance vital environmental processes while allowing residential growth and economic development t o continue . Envir· onmental resources, economic productivity, and live· ability are interdependent. Economic activities use en· vironmental resources, and are maintained by the envi· ronmental resources they are dependent upon. Li ve· ability, in turn, is determi ned by the intangible values of resour ces, both natural and social. Thi s interdepen· dency is limited by the fragility and finite number and type of environmental resources. In order to maintain both economic and environmental resources, ca reful consideration must be given to achieving a p roper bal· anc e between the competin g demands of growth, gen· erated b y economic expansion, and of preservation, to ma i ntain the sens itive character of ecosystems. 2 .2.1 COASTAL ZONE MANAGEMENT Description of Program Coastal Zone Management planning is a result of both the Federal Coastal Zone Management Act of 1972 and the Alaska Coasta l Ma nagement Act of 1977 . Both acts require that states use the nati on's coastal resources and promote their wise an d balanced use. The reassertion of the rightful responsibilities of local and state govern· ments in regulating the use and development of their coastal resources is a major aspect of both acts. The coastal zone management program must be con· sis tent with Federal and State law and regulati ons. Such programs must includ e, but are not limited t o, the following: • a description of the land and water uses and activities subject to the district program, and a description of geophysical hazard areas, recreation, transport ati o n CHAPTER TWO FUNCTIONAL ELEMEN1' 7 and utilities, energy facilities, and water-related activi- ties. • a description of the u ses and activities that will be considered proper and improper in the coastal area . • a statement of the policies that will be applied to l and and water u ses and activities subject to the district program. Issues The basic issue of coastal zone planning is to effectively manage coastal resources, while balancing the compet- ing claims of environmental protection and urban growth . Th is is a particularly difficult task, given the prox- imity of the coastal zone to major areas of economic and urban expansion. Municipal growth is expected to reach over 338,000 inhabitants in t he next twenty years, and the number of employees should in cr ease from 65,000 to a over 150,000 over the same time period. Confli ct s between various land u ses are sure to arise. The thru st of Anchorage's coast al zone program is to devise and impl ement a rational process for resol ving these con - flicts. Th is process should maintain the delicate bal ance among the economic, environmental, and social forces that ma i ntain human well-being; and i t must be flexible enough to respond to new information and chan ging perceptions of human needs. The resolution o f this issue, in the Coastal Zone Manage- ment (CZM } Plan, occurs thro ugh a process which identi- fies the sub-units of the total landscape accordi ng to sui tability of use . This process of land use suitability anal- ysis makes it possible to i dentify dominant and subordi- nate u ni ts of the landscape based upon a biophysical - cultural delineation of the coasta l area. In the Coastal Zone Management Plan, the concept of geogra- p h ic seg me ntation is used. This involves a division of the coast into different landscape resource units, each representing a different type of environme nt, and each exhibiting its own un i que characteristics. The terms u sed f or the several la nd use suitabi lity environments are: Preservation, Cooservation, and Utilization. Preservation Environment: This unit consists of geogra- p h ic areas characterized b y the p resence of environ- mental and/o r cultural features considered val uable in their undisturbed or o riginal condition, and which are 8 relatively intoler ant o f intensive human use. Such areas should be essentially free from development, or be ca p - able of being restored t o their natural co nd i ti on, and they shoul d be large enough to protect the value of the resou rce. Th e emphasis in this classification is on preser- vation or restoration cof natural sys tems, and on the prevention or regulati o n of u ses and activities which would degrade or destroy the natural environment. See Map 2-1. Conservation En vironm •~nt : This area consists of those l and and water areas having certain natural or institu- tional use limitati ons wl1ich requi re protection pri o r to their development. The purpose of this desig nation i s to protect areas for environmentally related purposes such as pa rks, food protection, and forestry management. It does not intend t hat the natural environment be main- ta i ned in a pure state; rather, that all activities and uses be ca rri ed o ut to prod uce min i ma l adverse impacts. Th e key factor i n this classification is the management of uses and activities to maintain the natu ral quality of the site. See Map 2-2.

Geographically, a mixing of features actually exists, since a given area may have attributes that require preservati on or conservation, and attributes that allow development. The CZM Plan establishes the processes whereby these competing uses and activities can be measured and judged, and a variety of management and engineering practices applied, to mitigate the impacts of urban pressures. The policies that are subsequently de- scribed focus upon the three management districts and establi sh the basic direction of Municipal action for each designation. Direction of Municipal Program The basic direction of the Municipal program regarding coastal zone management is described in the goals, objectives, and poli cies contai n ed in the adopted Coast- al Zone Management Plan. The plan itself basically pro- vides an analytical framework which includes a data inventory, a method for resolving the competing claims of development and environmental preservation, and a listing of the goals and policies that are to guide the decision-making regard ing this process. General policies have been deve loped for the three composite coastal environments and specific policies developed for each subunit contained within each environm~nta l c la ss. More detailed policies, goals, and objectives related to the actual geographic and bioph ysical processes of the coastal zone are given in Table 2-1 . Preservation Environments 1. Natural areas should remain free from all development which would adversely affect their natural character. 2. The intensity and type of uses permitted should be restricted i n order to maintain the environmental sys- tems and resources in their natural condition. 3. Uses wh i ch are consumptive of the physical and bio- logical resources, or which may degrade the actual or potential value of the preservation environment, should be prohibited. 4. Uses and activities in locations adjacent to natural areas should be strictly regulated to ens ure that the integrity of the preservation environment is not com- promised. Conservation Environment 1. New development shou ld be restricted to those uses which are compatible with the natural and biophysical limitations of l and and water. 2. Intensive commercial and industrial uses other than forestry, agriculture, energy facilities, fisheries, and mi n- ing should be discouraged . 3 . Diverse recreational activities wh ich are compatible with the conservation environment should be en- couraged. 4. Development which would be of a hazard to public health, safety, or the general welfare, or would materially interfere with natural processes should not be allowed. 5. Residential development should be regulated to mainta i n an overall density based on the carrying capac- ity of the land, or should be high density cluster units with open space and buffer zones surrounding. 6. Within the flood hazard zone, regulations should be developed which apply to development within the floodplains. The pri mary objective should be to prevent further development that is not water -dependent in those floodplains. 7. In areas with poorly drained or marginal soils, devel- opment should not be allowed unless connected to sewers. 8. Developments should be regulated so as to minimize the following impacts: erosion or sedimentati on; the adverse, direct, or significant i mpact on land and aquatic habitats; and degradation of the existing character of the conservation environment. 9. The Municipality should encourage sustained yield management of natural resources within the conserva- tion environment. Utilization Environment 1. Emphasis should be given to development withi n already developed areas. 2. Priority should be given to water-dependent and water-related uses over other uses . Uses which are neither water-related nor water-dependent sha ll be dis- couraged, except for residential. 3. Multiple use of the shoreline should be encouraged. 4. To enhance water related devel opment and to ensure maximum public use, industrial and commercial facilities should be designed to permit pedestrian waterfr ont activities consistent with public safe t y and sec urity. 5. Aesthetic considerations should be actively pro- moted by means of sign con trol regula t ions, architectu - ral design standards, landscaping requirements, vi ew shed requirements and other such m eans. 6 . Development should not significantly degrade the quality of the environment, including water quality, nor create conditions which would accelerate erosion, drainage problems or other adverse i mpacts on adja- cent envi ronments. 7. Redevelopment and renovation of existing areas should be encouraged in order to accomodate future uses and to maximize the use of coastal resources. 8 . New development in ru ral areas should reflect the character of the surrounding areas by limiting residential density (when Mun icipa l policy is to maintain a rural, l ow density environment), by providing permanent open space, and by maintaini n g adequate building setbacks from coastal and inland waters. 9. Recreational access to coastal areas should be encouraged. Recreational facil i ties should be located and designed to minimize c onflicts with other uses, activ- ities, and user groups not c ompatible w ith recreationa l uses. 10. To preserve and enhance the quality of residential development, priority should be given to the develop- ment of storm drain systems, including o n-site systems required to provide adequate d raina ge for subdivisions and structures. 13 2.2.2 Water Qua lity Management Description of Program The Water Quality Management Plan is concerned w ith water quality probl ems in t he Anchorage a rea created by non-point source pollution. Non-poi n t so urce pollu- t i on in an urban area consists of street runo ff, er osio n fro m constru ction sites, runoff fr o m snow d i sp osa l si tes, and si milar types of wastewater that do not originate from a single source. Water Quality Management planning is a result of Section 208 of t h e Water Po llution Con tro l Act Amendments of 1972. Under Sect:on 208, state governors can designate urban-i n d ustrial areas where there is a co ncern for e xist- ing and future water quali t y. These areas are then required to devel op p lans to c ontrol non-point source p o lluti on. These plans must co ntain strat egies to meet the July, 1 983, l egisl ative deadl ine for achieving a n ational interi m water qual i t y goal pertai ning to the pro- duction and propagation for fis h, shellfis h, and w i ldlife, and providing for r ecreation in and o n the nation's waters. Th is i nten m goal, com monly ref erred to as the f is hable/swimmable go al, is the primary objective of the Municipality's Water Q uality Management program. The Sta te of A laska Water Quality Standards reinforce the goal set by the Po lluti on Control Act by specifying c r iteri a or pollut ant levels for each water u se. All Anchorage cr eeks are c lass ified for all uses, i n c luding wat er supply fo r drinking, water recreation, and the growth and propagat ion of fish and wildl ife. Issues The purpose of the Water Q uality Management Plan is t o develop a coordinated set of are awide management contro l s over pollutant so urces t o prevent the degrada- tion o f water quality. The basic i ss ues addresse d by the Plan include rel ating u rbanization to pollutant levels, and establ ishing the proper kind and mix of controls to satisfy state and n ational pollution abatement st andards. The c urrent level of water quality in the Munici pality is quite high and most of the area's creeks are w ithin existing water quality standards of the State and Federal government. However, certa in violations do occur. Fecal coli form, suspe n ded solids, oil and grease, and heavy 14 metal s are defined as curre nt wat er quality probl ems under these standards. Analyses of the distribution of these vio lati ons indicate that w ater qua lity decreases with progression downstream. Th ese analyses have also indicated that the w ate r quality problems in areas undergoing urbanizaiton are solely cau se d b y non-point sources. Although the current level o f water quality is ge nerally satisfactory, maj or increases in urban iz ation are ex- pected to greatly affect these l evels. Over the next 20 years, about 8,000 additional acres are anticipated to be urbanized. The sediments generated during constru c- tion and the pollutants d erived from the r unoff of built- up, impermeable surfa ces will have t o be controlled to meet water quality standards. In addition, future pollu- tant sources are e xpected to parallel existing sources, wit h the greatest loadings being contributed from com- mercia l, i ndustrial, a n d hi gh-density residentia l land. It is e xpected that maj or increases in pollutant loads will result without prope r co ntrol measures be ing utili zed, resulting in the State and Federal standards for fecal col i form, suspended solids, and oil and gr ease being exceeded. n - 1 n c u [ [ Direction of Municipal Program The Water Quality Management Plan, in its preparation, identified three alternative levels of non-point source pollution controls to prevent the further degradation of Anchorage's creeks and improve future stream quality to meet water quality standards and criteria. The three control levels were designed to match three water qual- ity goals: a very high level of water quality sufficient to preserve streams for drinking water supply (Level 3); and intermediate quality level to achieve the federal require- ments of fish able/swi mmable waters (Level 2); and a l ower, less expensive water quality level reflecting the continuaiton of existing control efforts (Level 1 ). The first level involved the then existing program of con- trols to prevent stream degradation. This current pro- gram, although I)Ot specifically oriented to the protec- tion of water quality, st i ll represented an attempt at improving stream water quality. But studies of present and projected water qual ity in dicated that water uses would be impaired i n the fu ture without additional cor- rective actions. Level1 controls were not found to meet State and Federal legal requirements for water quality, nor would they protect on-going water uses . The controls utilized under Level 2 were based on a strengthening of Municipal practices designed to reduce non-point source pollution. Level 2 controls basically expanded upon the existing subdivision, zoning, and floodplain controls, and attempted to gear these mea- sures to the protection of water quality in a more satis- factory fashion. Restructured, these controls were fou nd to resu l t in water quality level s sufficient to protect all existing uses of area streams, but not to satisfy all of the requirements of State Water Quality Standards. The uses that would be protected under this l evel of control included secondary co ntact recreation and the growth and propagation of fi sh and wildlife. The strategies involved under Level 3 centered on developing an interceptor storm sewer system parallel to area creeks. This would ha ve the affect of diverting most urban runoff into Cook Inlet, thereby greatly reduc- ing pollutant l oads to area streams. This strategy would also include certain controls under Level 2 su ch as l i mit- ing the stockpil ing of petroleum supplies n ear creeks and prohibiting the d irect discha rge of wastewater to 2800 ~ MAXIMUM FECAL COLIFORM CONCENTRATIONS CHESTER CREEK .... ~ 2400 8 ..-........ z 2000 a. ~ I§ 1600 0 !!::: 0 v 120 iii v 800 " ... 400 10 9 8 7 6 streams. Level 3 actions would probably not improve water quality suffficiently to allow use of the streams for drinking water supply, although it could improve it suffi- ciently to meet primary contact recreation standards. Nonetheless, the improvement in water quality using the control strategies of this approach would be the great- est of all the alternatives. The approach selected b'/ the Municipality in its adop- tion of the Water Qual ity Management Plan focused on Level 2 strategies, which involved the current set of regulatory controls restructure d to better protect water quality. This approach applies control strategies related to each of the pollutant generating conditions asso- ciated with increased urbanization. These inc l ude non- point pollutio n from urban runoff, runoff associated with erosion from construction sites, runoff and percolation from snow disposal sites, and both surface and ground- water contamination resu l ting from the failure of on-site waste disposal systems. This approach was found to be the most cost-effective of the various alternatives. It was determined t o be effective in protecting the c urrent uses and users o f various streams; in minimizing environ- mental and social impacts otherwise associated with 5 4 River Mile Legend Year 1977 2000 --- Criterion (Proposed Standard) 3 2 0 major construciton activity; and in reducing cost require- ments for water quality protection measures, to both the public and private sectors. While these techniques were intended to focus on the individual sources of non-point source pollution, they were procedurally linked to an overall implementation strategy. Certain of the strategies were effective in reduc ing non-point pollution sources from several activities and functions. The current imple- mentation program of the Municipality retains and re in- forces this linkage between strategy areas. Municipal Policies Regarding Water Quality Manage- ment The manner by which the Municipality f o c uses the Water Qual ity Management program about the Level 2 ap- proach is expressed through two sets of strategies. The first is represented through specific control methods that affect building design and con struction and the manner in which land is developed. The second is expressed through goal s and pol icies relating to urban development and construction practices. The goal s, pol- icies, and objectives that are described in Table 2-1 indicate the overall d ire ction used by the Municipality in achieving water quality standards for area streams. 15 2 .2 .3 AIR QUALITY MANAGEMENT Description o f Program Following the occurrence of several violations of the ambient standards fo r carbon monoxide concentra· tions, the Mun icipality was designated by the Environ· mental Protection Agency as a nonattainment area. This designation necessitates the devel opment and imple- mentation of an air quality control p l an which would l ead to attainment of t h ese standards. The primary goal of the Air Quality Plan has been and will continue to be the attainment of the national ambient standards for ca rbon monoxide concentrations. This is to be achieved, however, wh ile maintaining compatibil- ity w ith other community goals. Scope of the Probl e ms The Clean Air Act Amendments of 1977 d irected the EPA to es t ablish air quality sta n dards for air poll utant s. Th e standards se t by the EPA for carbon monoxide allowed an area to exceed n ot more than once in a given year a concentration level of 9 parts of carbon monoxide per million parts of ambient air measured over an eight hour period. A special monitoring study conducted in 1978 revealed that the air quality problem associated with carbon monoxide was relatively widespread throughout the urbanized area of the Anchor age bowl. The monit ors revealed that those areas with high levels of t raffic and congestion, primarily in the downtown and the midtown areas, tended to show the highest concentrations of carbon monoxide. This inventory d e termined that 93 percent of the total emission s were transportation rel ated, pri ma ri ly from automobil es and li ght tru cks . Abou t 5.1 percent of the pollutants were from small i n dustrial so urces, su ch as electrical generating plants and aircraft operati ons. Commercial and large industrial sou rces contributed . 7 percent, and residential fuel consumption was respon- sible for less than one half of one percent of the pollu- tants. In terms of the geographic distribution, the inven- tory revealed that those areas which would be expected t o have high level s of traffic volume, would also be the areas of highest pollutant emissions. Both the downtown and the midtown areas were i dentifi ed as either havi ng, 16 or exhibiting the potent ia l for having, high carbon mon- oxide concentra:ions. Large employment centers which attract high traffic volumes, tend to suffer most from air quality probl ems. As congestion increases, average speeds decrease, and pollutants increase. The large number of employees in these ar eas adds to the overall pollution load due to the "cold start" phe- nomenon. Cold weather substantially increases motor vehicle carbon monoxide emiss ions. The maintenance of vehicles is more difficu lt during cold periods and engines take much longer to reach the proper operating tem- peratures of the pollution control equipment. Conse- quently, ca rbon monoxide emiss io n s durin g the i nitia l stage of engine operation are typically much h i gher, and may accou nt for more than 90 percent of the t otal vehicle trip emission s. Because of the l arge number of commuter automobiles w ithin the commercial and retail areas and other employment cen t ers, the p h enomen on is more pronounced at the end of an average work day, as these veh icles are start ed cold for the trip home. Although the Federal ai r pollu t i on control program is designed to limit automobile emissions, it is not ex- pected that ai r qual ity standards will be met in A n chor- age unti l the early 1990's. Population growth will con- t inue to redu ce most of the advantages to be gained from the motor vehicle pollution control program. In addition, once the standards have been met, average pollutant concentrations are aga i n expected to in crease with continued increases in population and automobile use. n ,..., n ....., J \ J ,-l J J J ~~ .J J I J J J Direction of Municipal Program In order to reduce carbon monoxide concentrations to acceptable levels, it will be necessary to implement a number of air quality control strategies. A balanced approach between air quality improvements, public and institutional acceptability, and cost is to be incorporated into the Air Quality Control Plan. It will also be necessary to ensure that the various strategies are clearly interre- lated. Often, the implementation of any one strategy will also require the implementation of another strategy to be fully effective. Because of the complexity of the air quality problem in the Anchorage area caused by the cold start pheno- menon, it is not known whether conventional transpor- tation control measures will be totally effective in reduc- ing pollution levels. The full extent of the contribution of cold start to carbon monoxide emissions is not yet known. To achieve the necessary reductions for attain- ment of the carbon monoxide standards, cold start strategies will need to be developed, in addition to the more conventional transportation control measures. Strategies which are being considered for inclusion in the Air Quality Plan may include all of the following: • Pedestrian facilities improvements • Inspection and maintainance programs • Cold start strategies • Public transit improvements • Parking management • Variable work hour programs • Traffic improvements (high and low cost) The goals and objectives to be used by the Municipality in the air quality efforts are given in Table 2-1. £ NORTH ~ ONE MILE ANCHORAGE NONATTAINMENT AREA Municipality of Anchorage 3/77 ~Boundary 17 TABLE 2-1 GOALS, POLICIES, OBJECTIVES: ENVIRONMENTAL COMPONENT Comprehensive Plan Element or Sub-Element Environmental Freshwater Marshes Wetlands, and Coastal Marshes Goals To ensure that the natural environment is enhanced, maintained, and protected by establishing standards for the protection of soil, vegetation, air, sound, and sight with appropriate surveillance and enforcement to these standards.

Th e funciton of this syste m is to connect the activity areas associated with particular patterns of land u ses. It allows human interaction to occur through the movement o f people and goods. Besides the function of redu ci ng the ba rriers of time and distance, the transportation system performs severa l additional services. A ll of these requi re the considera- tion o f transportation, within the context of economic and land patterns. Transportati on, al ong with water and sewer f acilities, serves as a princ i ple determiner of land u se patterns and densities. The accessibili ty provided by tran sportation creates and fosters land development. For this reason, transportation i s an essential element of all land gui d ance programs--such as t h e program stipu- lated in this Plan. It also provides a strong support func- t ion to land use development by allowing economi c and human interaction to occur on a convenient, economi- cal basis. Its ability t o influ ence the rate an d pattern of overall economic development is hig hly significant. The importance of transportation in this regard can not be overstated, particularly in p r o viding access to major industrial facililties and to the major regional shopping centers of th Downtown and Midtown. Th e relationshi p between transpo rtation and land use p l annin g is eminently c ri tical becau se of the important spati al, physical d evelopment orientat ion of the Com- prehensive Plan . The land use patterns identified herein rep resent d esired Municipal policy regardi n g urban development patterns and densities. Because Transpor- tation form s a necessary link to the creation o f these patterns, it is perhaps the most i mportant of all urban infrastructure elements affecting land development. 2.3.2 Issues The transportation system is con front ed with increasing service demands, derived fr om expect ed increases in both population and economic growth. The rate an d leve l of growth actuate the requirements for an ever- increasing transport ation network. The ce ntra l iss ues of 26 tra nsportation planning concern h ow and t o w hat extent transportation services can be developed to accommodate these expected increases in urbaniza- tion. The projected volum e of trips generated between activi- t ies indicates t h e expected demand for increased t rans- portation services. The Anchorage Metropolitan A r ea Tran sportation Study es t imat ed that 802,000 trips wer e made i n 1970. In contrast, by t h e 1995 design year of the Long Range El ement Pl an, nearly 1,451,000 su ch trips are projected. If these estimates are real ized, and t he increase in person -trips over the l ast ten years see ms to i ndicate the likelihood of this, major inc r eases in the level and kind of transportation facilities and services must be provided . A basic consideration in transportation system expansi on is the l evel of modal split. This level i n dicates the a mo unt, as a percent, of the total number of person- t r ips made u sing t ransit. Presently, only 1.5 percent of al l such t rips are made by transit. Nonetheless, it is expected that. by the year 2000, ten percent of all person-trips w i l l be ma de using transit. Whether this level of diversion, fr om the private sing l e-occupant automo- bile to the more energy-efficie nt modes of transit and carpooling, ca n and will be made is a major variable in devel oping the transport ation system . Certai n secondary issues are c reated th r ough transpor- tation im provements. These impacts are generat ed by the expected growth of the system, and include consid- erations of energy utilization, the impact on air qua li ty as vehicle emiss i ons grow, and the fina n c ial costs of system development. Energy Utilizati on As the numbe r of veh icl e trips increases, gasoline con- sum ption tends to increase proportionally. As described in the energy component of the Comprehensive Plan, the scarcity an d cost of gasolin e and other petroleum products are expected to rise over the n ext several decades. Therefore, the developmen t o f an energy-eff- cient transportation system must be a main considera· t ion to continued community mobi lity. Transportation planning must fo c us upon the necessary modifications in cultural attitudes and behavior patterns, the creation of mechanisms to ensure the provisions of transportation servi ces under reduced petroleum supplies, and the ability of the transit system to accommodate expect ed r ises in ridership. Air Quality Sim il ar to the impacts upon e n ergy consumption, the increasing number of vehicle trips projected by the year 2000 shou l d markedly impact levels of ca rbon monoxide emission in t h e metr opolitan area. A n chorage is cu r- rently design ated as a car bon monoxide non-attainment a rea by the U.S . Environmental Protec tion Agency, and si gnificant incre ases in the level of carbon monoxide in this area are discouraged. These levels are especially high at intersecti ons in the Midt own and Downtown n D 0 1 u areas, which accommodate large volumes of vehicular traffic, especiall y during the peak-hour periods. It will be necessary to develop both an impr oved transit system and increased us ed of alternative transportation modes, such as vanpools an d carpools, to effectively reduce carbon monoxide emissions to amounts consistent with both Federal and State standards. Some for of ve h icle inspecti on-maintenance program may also be necessary. Financial Resources Th e need for improved transportation are reflected in the costs to develop such a system. These costs exist for both roadway and tra nsit improve ments, and total1 ,35 7 million dollars in 1978 prices . Th e costs of the roadway system al one ar e ex p ect ed to reach $765 mi lli on, while that of the transit system could be $592 mill ion. The revenue projected to be available for these facilities only approach $841 mill ion. The ability of the Municipality to derive additional funds, re-allocate funds from other activities to transportation, or r edu ce transportation expenditures, are all issues facing the Municipality over the next 1 0-20 years. 2 .3 .3 DIRECTION OF MUNICIPAL PROGRAM The policy of the Municipality is to develop a integrated, multi-modal transportation system that balances im- provements in transit and highways. The rationale for a bal ance d development approach is derived from the previously described issues . Because o f increasing petro- l e um costs, es calating operating and construction costs of both facilities and vehicl es, and impacts o n air qual ity caused by a rapidly increasing ve h icle f leet, it is essential that passenger-efficient t ransportation modes be deve- loped. Emph asis mu st co ntinue in developing a transit system and alternative modes p r ogram. that is increas- ing aggressive i n its attempts to divert trips from single- occupant vehicles. Roadway improvements necessary to accommodate projected single-occupant vehicl e volumes are identi- fied in the Anch orage Metropolitan Area Tran sportation Study Long Range Element Transportation Pl an. See Map 2-3. The Tr ansportation Pl an tries to use existing rights-of way for highway improvements and, i n the few instan- ces where new roadways are projected, t o phase these improvements in resp o ns e to incremental increases in volume. M uch of the expected traffic vol ume carried b y the r oadway net work should be funneled within the three major corridors of the Glenn Highway, the New Seward Highway, and the Minnesota Bypass. These facili- t i es should accommodate most of the intra-urban trips that have trip destinations of over fi ve miles. Th e provision o f trans it facilities is an essential aspect of the Long Rang e Transportation Plan, and will be required to relieve overcrowd ed road systems, as well as allow added mobility. A modal spl it l evel of 1 0 percent is ass umed i n the Plan . This will require a major expansion of fleet size, to a fleet of 540 by the year 2000. Currently there are 31 buses on 14 routes in the Anchor age Bowl. Bus system devel opment wi ll con centrate on usi ng a grid route system w hich tends to be more effective in provid- ing accessibility under patterns of higher urban densities. Feeder routes with coordi nated transfers are being designed for the low density areas where transit services wi ll be provided. It wil l also conce ntrate upon the devel opment of express bus facilities from outlying resi- dential areas to inlying employment centers, especially at the Midtown and Downtown. The Tran sporation Plan recognizes the potential for light rail development and high occupan cy vehicle lanes along primary transit corri- dors. Two primary transit corridors are to be established: the more central portions of western and eastern 27 Northern Lights and the C Street corridor extending to south Anchorage. It is Municipal policy to concentrate transit sys t em improvements i n these corridors, and to establish and enco ura ge land use patterns t hat create the higher densities required for line-haul express bus systems . Lastly, the Transportation Plan deals with developing an alternative mo d es program, and with providing the sup- port fa ci l ities desig n ed for pedestrian and bicycle fo rms of transpor t ation. Th e pedestrain and bikeway forms of transportation are intended to be integral parts of the overall transportation sys tem, and are indentified at l ength i n the Areawide Tra i ls Plans . The alternative modes p rogram concent ra t es on the incre as ed use of carpo o l ing and vanpooling, and the establishment of a management system which e mphasizes the staged development of transit faci lities and alternative modes strategies. The systems o f walk ways and bikeways are intended to provide access to and within residential areas , to connect residential areas with schools and major activity centers , a nd to form an a ccess pattern t o major recreational and o pen space reso urces and to transit corridors. Although discussed se para tely, each transportation mode is intended to p r ovide an impo rtant l i nk in the way in which people are transported within Anchorage. Municipal pol icy is to encou rage an expanded use of the transit sys t e m, and to make mo re efficient use of road- ways through the inc reased use o f alternative. modes progra ms. This shoul d bal ance roadway con stru ctio n with the development o f the other, more efficient trans- p o rtation modes. 2 .3 .4 TRANSPORTATION POLICI ES AND GOALS The transportation pol icies and goals of the Municipal ity, given in Tabl e 2-2, reinforce the previous reco mmenda- tions to develop a balanced, multi-modal transportation network. These goal s and policies have been derived from previous transportation studies (partic ularly the Long Range Transportation Pla n ) and from the publ ic parti cipation process associated with the development of the 1976 Comprehensive De v elopment Pl an. They are meant t o be con sis tent with the Comprehensive Plan, and are designed to rei nforce the desi r ed land u se pat terns and densities given in Maps 3-1 and 3-2. 28 n Metropolitan Transportation Improvements ( (, I ; POINT CAMPBELL Municipality of Anchor age Anchorage Comprehensive Development Plan 1 Kilometers 2 D K INCAI D R O AD -Freeway • I nterc hange • Grade Separati on IIIII III Maj or Arte rial -Mino r Arteri al M ap 2-3 ELMEN DORF A IR FORCE B ASE I I I I I I I I I I I I I I : ~------.

Whereas other compo- nents of the Plan focus on such basic human needs as shelter, work, and mobility, the Parks, Trails, and Open Space component focuses on another basic need -- communitywell being. The function of a parks and open space system within Anchorage is to provide space for a range of leisure activities, and to retain a dimension of the natural environment as a part of the overall design of the community landscape. Population pressures and availability of leisure time have brought needs for recreational space and facilities. They have also brought an intangible psychological need for visual refreshment, and mental exercise away from rou- tine home and work environments. Population pressures resulting from a rapidly growing community have also brought a need for establishing pride, personality and stability to the surrounding environment. The establish- ment of a functional parks, trails, and open space system is key to meeting these community needs in Anchorage. Anchorage has a finite amount of land available upon which to accommodate future population growth and economic expansion. Competition for ldnd for residen- tial subdivision, industry, shopping, schools, and many other uses will continue. It is important that appropriate lands to be dedicated for parks, trails, and open space. The Parks, Trails, and Open Space component of the Comprehensive Plan addresses the land needs, geogra- phic distribution and spatial relationships of parks, trails, and open space to other land uses within the Anchor- age Bowl. 33 l 0 t 0 "d iii 11 •• o ~o=rn a .. =l Heavy Ti"mber. Fence--7S. . 0 10 25 . 50 --COPE SCALE The Parks, Trails, and Open Space component contains a system consisting of three inter-related elements: • Parks • Trails • Greenbelts and Other Open Space Detailed descriptions and analyses of these elements are contained in the Areawide Trails Plan and (draft) Parks, Recreation, and Open Space Plan. • As proposed in these plans, the parks and open space are largely uni- fied into a system with trails and greenbelts (or natural corridors) forming links among the major parks and edu- cational facilities. When these plans are implemented, most Anchorage residents will be able to have recrea- tion opportunities close to home and connections to parks throughout the Anchorage Bowl. 34 I COPE STREET PARK ~ R. revised 11-29-78 Methods by which park, trail, and open space land allo- cations and acquisitions are made will vary. Parks -- whether serving neighborhoods or greater segments of population--are planned according to a series of stand- ards. The acreage allocations for parks are directly related to the population of an area. However, the open space system allocations are based on environmental, social, and recreational values which are not necessarily tied to population. These values include protection of such natural areas as stream corridors, wetlands, and woodlands. Acquisition of park, trail, and open space lands vary, from fee simple purchase to dedication of easements through the platting process. Map 2-4 graphically depicts those park, open space, and related public uses that are com- ponents of this program. This plan, and its spatial ex pres- sion in Map 2-4, is meant to provide a general direction to the development of the Municipality's open space and park programs in terms of acquisition, development, and related land use decision-making. Neither this plan nor Map 2-4 are meant to specifically exclude compat- ible uses in areas identified as parks and open space nor do they constitute a dedication of these areas for park uses as specified in the Municipal Charter. 2.4.2 PARKS Description of Program Traditionally viewed as passive nature-oriented areas, many parks today also serve a major function of provid- ing active recreational opportunities for people of all ages. Thus, urban parks systems are composed for pro- perties that vary in size, location, function, service area, and development. Parkland need is primarily based upon a series of recrea- tion area standards. The acreage allocations for parks are directly related to the population of an area. Standards for parks were development in the early 1970's by the National Recreation and Park Association. Anchorage has employed these standards in park acquisition and facility development during the past decade. The ana- lyses and projections of future park land needs are based upon these standards. The standards divide parks into three groups based on the areas that they serve: ( 1) those that serve one neighborhood, which would include playlots, vest pocket parks, and neighborhood parks; (2) those which serve several neighborhoods of a community, which would include community parks; (3) those that serve a large section of the Anchorage area or entire metropoli- tan area, which includes large urban and regional parks. (See Table 2-3 for a listing of the park standards utilized in Anchorage). Following is a brief description of each park type: Playlots: Small areas intended for preschool and ele- mentary school children, with provisions for adult at- tendants. Greatest need in areas of high density where backyard play opportunities are not available. Vest Pocket Parks: Intended to serve specific groups depending on character and needs of immediate neigh- borhood. May serve children, senior citizens, or all age groups. These are usually vacant lots converted to recreation use. 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 D 0 0 0 0 0 0 D Russian Jack Springs Park • N Scale : 1'' = 540' MR 2-13-79 Neighborhood Parks: Intended to provide areas for both passive and active recreation for people of all ages. Usually serve about a square mile of urban area and population ranging from 2,000 to 10,000. Size ranges from 5-20 acres. Location next to elementary schools are preferred. Community Parks: Intended to supplement neighbor- hood parks in providing near-at-hand recreation areas. They provide space for those recreational activities which can not be accommodated within a single neigh- borhood park. Intended to serve 10,000-50,000 peo- ple. Size ranges from 20-100 acres. Locations next to secondary schools are preferred. Large Urban Parks: Intended to serve all residents within Anchorage Bowl. At least 100 acres in size, these parks generally have a mixture of natural areas and developed special facilities. Such facilities may be golf course, trails, nature center, boating, swimming or picnic areas. Regional Parks: Basically large land preserves with natu- ral orientation. Development limited and oriented to outdoor activities incidental to maximum enjoyment of nature and natural scenery. Should be located within one hour drive of urban area. The value of using these standards are threefold: • Standards provide a systematic means to approach park acquisition and development; • Application of standards help to promote the equal distribution of park land and recreation facilities from one community to another; and • Standards help to maintain a balanced system of parks, providing a wide range of recreation opportunities. Issues In total acreage, Anchorage would at first appear to have a substantial amount of park acreage with which to accommodate future population needs. However, it is very important to note the location and function of most of the park land. Currently, Anchorage has over 6,600 acreas in Municipal parks and open space. By far, the greatest portio::>n of that acreage is in the ten large urban and regional parks--of which two are located in the Eagle River /Chugiak/Ek- lutka area, and one at Bird Creek along Turna-gain Arm. Following is a summary of Anchorage municipal parks and open space by type: Vest Pocket and Neighborhood Parks Community Parks 227.45 acres 4 7 5.87 acres Large Urban and Regional Parks 5832.70 acreas Although they comprise the least amount of acreage in the parks and open space inventory, vest pocket and neighborhood parks are the most numerous, totalling 65. Community parks total 11, and large urban and regional parks total 10 (including Section 16 and Pt. Campbell Military Reservation). In regard to land acreage needs, and relative geographic distribution, there is an ample amount of large urban and regional park land to meet current and future popula- tion needs. This is particularly so if Chugach State Park (495,000 acres) and Campbell Airstrip Tract (4,000 acres) are also considered. The foundation of a good park system, however, is at the neighborhood and community park level. Current and future needs for playlots, vest pocket, neighborhood, and community park lands vary within the Anchorage Bowl. By using the park land standards, current and pro- jected park land needs are identified for each of the sub-areas, or communities, within the Anchorage Bowl. Priorities are established in order to focus near-term park land acquisition in areas where current needs are greatest. Direction of Municipal Program The direction of the Municipal park program is toward further park land acquisition and development com- mensurate with current and projected population growth. The focus of park land acquisition will be at the neighborhood and community level. Unlike large urban and regional parks which were originally public lands, community, neighborhood, and vest pocket parks have primarily been privately owned lands requiring acquisi- tion, in most instances, by fee simple purchase. This circumstance is not likely to change. Higher acquisition cost will require thorough evaluations of sites to be considered for additional park land. A number of strate- gies will be employed. Most notable are: 35 Classification Playlots Vest Pocket Parks Neighborhood Parks Community Parks Large Urban Parks Regional Parks Special Areas & Facilities *Not applicable Table 2-3 STANDARD FOR PARKS BY CLASSIFICATION AND POPULATION RATIO Municipality of Anchorage Acres/ 1000 People * * • 2.5 2.5 5.0 20.0 * Size Population Service Range Served Area 2,500 sq. ft. 500-2,500 Sub-neighborhood to 1 acre 5,000 sq. ft. 500-2,500 Sub-neighborhood to 1 acre 5-20 acres 2,000-10,000 Y4 -% mile radius 20-100 acres 1 0,000-50,000 %-3 mile radius 100 +acres one per 50,000 Within %hour driving time 160 +acres Entire population in smaller Within 1 hour driving time communities; need distribution throughout larger metro areas Includes parkways, beaches, plazas, historical sites, floodplains, downtown malls, small parks, tree lawns, etc. No standard is applicable.

An additional strategy that is recommended is the estab- lishment of a Municipal land bank of surplus property. Revenues derived from the sale of surplus Municipal lands would be appropriated for acquisition of neigh- borhood or community park land where needs are grea- test and land availability through other means more scarce. Use of these strategies will result in a well-balanced, equitably distributed park system that will provide recreation opportunities accessible for all age groups to enjoy. 2.4.3 TRAILS Description of Program Trails serve a dual function in Anchorage. They are a recreational facility from which a variety of leisure time enjoyment is derived. In addition, they are also an inte- gral part of the total transportation system, thus provid- ing mobility and accessibility to areas and facilities by various modes of travel. Details of the Municipal trails program are contained with the adoption Areawide Trails Plan. The trails plan is intended to be the basic policy document for develop- ment of trails in the Anchorage area. As such, it serves as the basis for establishing and maintaining access routes and use areas as they relate to community centers and recreational activities. The Trails Plan identifies trails that serve a variety of modes for travelling safely and enjoyable without auto- mobiles or other large motor vehicles. The trails are intended for bicylists, pedestrians, equestrians, dog mushers, cross-country skiers, snowmobilers, joggers, handicapped persons, and to a lesser exte:nt, motor- cyclists. The Trails Plan identifies the general location for trails development and the types of uses associated with the development. Issues Anchorage is a community of outdoor enthusiasts with a wide variety of summer and winter-time trails interests. Some uses are compatible on the same trail facility (jog- ging and bicycling), while others are not (horseback riding and motorcycling). Some trails require special facilities for a specific group of users (handicapped per- sons trails), while other trails must be located in very specific site areas (dirt bike trails). Because trails serve a variety of users, they vary in design, locationa:l, and aes- thetic characteristics. Major issues center on specific route or site selections, impacts on surrounding area, and the joint use of facilities. Direction of Municipal Program The Areawide Trails Program identifies the general loca- tion of the various types of trails. In so doing, it has separated the non-compatible trail users. It has also identified certain design requirements and administra- tive procedures necessary to implement the proposed non-motorized trail system and motorized use areas. The major emphasis of the Municipal trail program con- cerns the further refinement of the recommended trail corridors and implementation. The Trail Plam specified general corridor locations for trail development but did not identify particular route locations. These more spe- cific locations are required for the reservation of ease- ment as part of subdivision plats. Implementation of the trail corridors is to occur through the development of the area's overall transportation system and through the use of available--and future--utility and roadway right- of-way. It is the policy of the Municipality, expressed through the adoption of the Trails Plan, to treat bikeways and the other various forms of non-motorized transport as important elements of the overall transportation sys- tem. As such, these non-motorized circulation systems are to be incorporated where feasible, as part of high- way improvements and major new road projects. It is intended that this general policy will be expressed in multi-modal transporta~ion projects; the development of of an integrated system of non-motorized circulation forms providing access to principal trip generation cen- ters, including schools; and in the establishment of multi- use transportation corridors. The continued application of this multi-use concept in transportation system development will eventually result in the establishment of an integrated trail-highway circu- lation system serving major trip origins and destinations. In addition, Municipal policy shall also continue to focus on the development of motorized use areas that do not conflict with residential areas and established non- motorized ues.ln practice, implementation of this policy will require the increased cooperative use and man- agement of nearby State and Federal lands. Motorized uses are largely incompatible with most urban activities and require large, open spaces only available in adjacent State and Federal lands. 2.4.4. GREENBELTS AND CONSERVATION AREAS Description of Program The greenbelts of Anchorage area a vitally important system. They are natural landscape corridors that link neighborhoods, parks and schools, and act as buffers between different land .uses. They help define the physi- cal form of the city by. contributing to its memorable character and creating unique neighborhoods. Following the east to west flow of Chester and Campbell Creeks, the best of the greenbelts remind us of Anchor- age's dramatic sea and mountain landscape. In the greenbelts, Anchorage residents and visitors can walk, run, ski and ride from the Chugach foothills to Cook Inlet 37 without conflicts with vehicular trattic, and free from city noise and congestion. The greenbelts link many out- standing city parks and their diverse facilities into a con- tinuous recreation system. They provide the opportunity to preserve special places-quiet woods, wetlands and wildlife habitats -for public enjoyment in their natural state. Greenbelts contribute the inost amenity when they are easily accessible to residential neighborhoods. Residents of adjacent housing developments can take advantage of increased recreatio,n opportunity and transportation alternatives. A major objective of this plan is to join neighborhoods to park 'land through open space corridors. The greenbelt element of the Parks and Open Space Plan is designed to complement the overall land use plan. Corridors are identified: • to conserve natural features of lahd; I • to serve as buffers between different types of land use; • to lend definition to neighborhood areas; • to provide links between residential areas, education facilities and existing park lands; and • to provide recreation opportunities close-to-home, minimizing time and barriers to participation. Issues Three growth-related isses form the context of the pro- posed additions to Anchorage's greenbelt system. The recommendations include both the development of already adopted greenbelts and the adoption of new ones to complement the system. These greenbelt pro- posal plans are made with considerable urgency: Anchorage is at a critical point in its urban development. Heretofore, private undeveloped land was easily access- ible for casual recreation use. That option is rapidly disappearing, particularly for linear trail activities. People find that their usual dog mushing, horseback riding and skiing trails are blocked by new residential subdivisions. Suitable recreation land should be reserved before presently vacant land is fully develbped. Greenbelt proposals address a s~t of water-related issues. The urbanization of the Anchorage Bowl has strained the area's hydrologic system by increasing demand for water, changing ground water flow patterns, 38 u 0 0 0 - r d 0 0 0 . 0 0 0 0 0 D 0 0 0 0 0 0 0 0 D 0 0 0 D 0 and increasing surface runoff. The protection of stream courses and wetlands is necessary to preserve water quality. Recreation is often the only appropriate use of stream corridors and wetlands that are unsuitable for other land uses. Anchorage has a policy of establishing stream corridor open space, i.e., Chester and Campbell Creek greenbelts. The new greenbelts proposed by this plan continue this policy. In addition, the plan proposes reserving certain highly valuable wetlands as dedicated open space, with residential development planned for surrounding land. The third issue affecting greenbelt concerns the oppor- tunity for the restoration of former gravel extration sites. Through careful design and landscape reconstruction, these sites will be able to accommodate future housing which reserving greenbelts as an integral part of the development. Greenbelts and Other Open Space The current Municipal greenbelt system has two catego- ries of greenbelts, distinguished by different levels of development. The two most completely established greenbelts are Chester Creek and Campbell Creek Green- belts. They constitute one of Anchorage's most impor- tant urban recreation resources. The Municipal Assembly has also adopted, but not developed fully, Fish Creek and Rabbit Creek Greenbelts. Other undevelopable tracts supplement the system, and are reserved as natu- ral open spaces. This Parks and Open Space Plan proposed the following greenbelt and open space additions (see map) to the present system: • Sand Lake Gravel Pit Restoration • Sand Lake, Sundi Lake and Jewel Lake Open Space • South Fork of Chester Creek Greenbelt • Klatt Bog-Connors Bog Greenbelt and Connors Lake Open Space • Nunaka Valley/Cheney Lake Greenbelt • West Turnagain Greenbelt • University-Muldoon Area • Muldoon to Merrill Field Greenbelt • Furrow Creek-O'Malley Greenbelt r~:~:~va Pn-~=]~~~·~~;~:j!······~····~·)~\~\~··:~,·~··~~~~~~l~~~=~~ IIIII ~ -?PI><:E.' 0~ ~ !\1UNIUI'"Al--l'"~? cONCEPT: • Little Campbell Creek Greenbelt • Birch Road -Hillside Drive Greenbelt • Little Rabbit Creek Greenbelt • Potter Creek Greenbelt and Johnson Trail Corridor • North and South Forks of Campbell Creek Open Space • Fish Creek Estuary Open Space The proposed additions are based on the premise that greenbelts should be reserved before areas are deve- loped1 thereby avoiding costly and difficult acquisitions in built up areas. When new residential developments, parks, and greenbelts are planned at the same time, neighborhood residentials are able to get the most advantage form well-located and cost-effective outdoor recreation facilities. Highlights of these additions illus- trate this integrated planning approach. The Rabbit Creek Greenbelt is considered a "Special Study Greenbelt" within the context of this Plan. The concepts are: 1) to provide creek maintenance provi- sions along the creek from Buffalo Street to the west, and 2) to provide both creek maintenance and public access along a linear park from Buffalo Street to tine east. The "special study" will be carried out as part of the Park1 Greenbelt and Recreation Facilities Plan. 39 • Sand Lake Greenbelt The Sand Lake gravel pits can be restored to accommo- date residential development. A unified restoration/ de- velopment plan should provide hou~ing at variable den- sities, and reserve greenbelts througn housing areas. The public greenbelts would be bounded on both sides by private land. Variable width corridors could link tot lots and neighborhood parks, and provide trail connections to Sand Lake, Jewel Lake, Jade Park and Kincaid Park. ~VATE LAND ~lc:e-l11Al-7\NEoW'O--- C.,Ul-·DE'-o?>£1? fA/l'\11 . .: i.JU!'?IN6 II ~ECTION 40 , " 1'1.-AMll NG AND "-ANDFO~~a-1 Y~WIDTI-1~ \lZAII-'? ~ f'A~.!::~ PRJYATE LAHD ~ ( -'?!New;;. ·FJOo.I'Y\Il-\ J:AIW? \40Ll?1No 0F\EENDEL T 111~ F-ESIOEN"TW.-I'-1Etfr1E::C:fii20DS IN Ke-5-n:::::::R--ED ~D LAKE. qf:.AVE..L Fl~ LJ 0 0 n L ..

The concern for energy usage originated primarily from the oil embargo of 1973-1974. Since that time, energy supplies, and their allocation, have been a continuing concern to this country, and to Alaska specif- ically. It is safe to assume that this concern will continue well into the foreseeable future. The supply and cost of petroleum greatly affect lifestyle, c ustoms, and behavior. The fact that energy has become a significant, long-term problem requires that it receive consideration in com- prehensive planning . This Plan element provides a gen- eral framework for energy planning and specifies poten- tial energy programs for use by the Municipality. Th is element is not, however, an overall energy devel- opment and management plan for the Municipality. Such plans are more intensive, encompassing energy conser- vation measures for such activities as industrial pro- cesses, transportation, public utilities, Municipal ser- vices, buildings, and government operations and procure- ment. Energy management plans assess the systematic pattern of energy flows, and develop an integrated pro- gram to ensure the effective linkage of these patterns. This report element is intended to form a relationship between land use and energy patterns, and to specify those strategies associated with more efficient land use and transportation energy consumption patterns. 2.5.2 NATURE OF POWER DEMAND REQUIREMENTS The characteristics of electrical power demand are ana- lyzed in a recent report, Upper Susitna River Project: Power Market Analysis. This study on ly analyses the need for added electrical power generation, although this medium adequately demonstrates the relationship between land use and energy conservation patterns. More studies are now being prepared, and should update much of the supply analysis of electric! power demands . Nonetheless, the Upper Susitna study pro- vides a genera l indication of power requirements for the Anchorage area, for both the near-and intermediate fut ure. It is instructive in the need for conservation, as well as supply development, measures. 2.5.3 PAST DEMAND CHARACTERISTICS Electrical power demands over the la st ten years have shown that the major energy use determinants were the construction of the Tran s-A la ska oil pipeline and the 011 embargo of 1973-1974. In general, there has been an increasing demand for e l ectrical power by all use sectors including residential, commercial, and industrial . The analysis determined that a major change occurred, after the 1973-197 4 gaso line crisis, in the rate of energy growth, and concluded that conservation should be considered as a major factor in planning beyond the 1973 period. Projections of electrical power demand indicate a fairl y severe shortage of available capacity beginning about the 19 85-1990 period. Even though the area's utilities are expected to add considerable capacity during this period, available capacity may be exceeded by the 1985 period . Thereafter, the demand-supply situation wiH worsen, approaching a deficit of nearly 1.3 MW by the year 2000 if additional capacity is not installed. The primary conc lu sions derive d from the Susitna analysis included the need for : • Substantial power generation increases over the next 15-24 years, and • Phased energy development strategy, and • Increased energy conservation, to forestall part of the expected power increases . The importance of energy conservation measures can best be appreciated when it is realized that the power generation forecasts in clude a large energy conservation factor . Because of the nature of the projected demand- supply relationship over tne next fifteen years, con- sideration must be given in energy supply and energy management planni ng to both the provis ion of addi- tional supply as wel l as the development of effective energy conservation programs. The Upper Susitna anal y- sis has indicated the need for both approaches and the need for them to be close ly integrated . 2 .5 .4 RELATIONSHIP BETWEEN LAND USE AND ENERGY MANAGEMENT PLANNING Research on the energy demands of land use patterns has recently emerged, and rnost have conc urred that the v arying patterns effect the amount of energy we con - sume, particularly for transportation, and space heating and cooling. What remains unclear is t he extent to which changes in land use can reduce the genera l level of energy consumption. Yet, in spite of divergent opinions, most studies identify energy conservation goals that land u se decisions can promote. Energy consumption patterns are directly tied to specific community environments. A recent State study analyzed the impacts of alternative community forms on energy consumption levels in an ar ea near Anchorage. It indi- cated fairly specific relationships between energy con- trol measures and land use patterns. In analyzing the effects of different urban patterns and densities, marked decreases in energy use accrued through even modest increases in density. More rapid decreases in energy use were not apparent beyond an urban structure that is fairly concentrated . In this study, the creation of moderate densities in southcentral commun iti es resulted in an 18 percent decrease in energy use compared to typical decentralized urban forms. The residential se c tor had the greatest impact in these relationships, constituting nearly 70 percent of all energy consumption needs. Equally important, this sec- tor is especially sensitive to changes in land density and use patterns. A fairly direct relationship between land use patterns, transportation, and energy co nsumption also exists. The pattern and density of land development affects the number of ve hicles required, miles traveled, and mode used in travel. Urban forms having moderate densities decreased total transportat ion energy consumed by 50 percent or more from a baseline, decentralized growth pattern . A centra liz ed land use pattern decreased trip making b y an even greater amount. These are significant results since they replicate the levels of energy reduction that can occur in other communities. In addition to the possible energy savings derived from space heating and intra-city transportation efficiences, significant energy savings c an also re sult from incorporat- ing community-wide and individual building energy con- servation techniques. Exam ples of such techniques might include : 49 • Improving individual building design and equipment selection, • Converting Municipal waste to supplement steam in power plants, and • Improving siting and orientation of buildings. Large reductions in energy consumption would accrue through the use of these techniques compared to the baseline energy case, and co u ld approach a reduction as great as 53 percent. The previous analysis stresses the importance of land use planning to energy conservation, and indicates the impact of even modest chan ges in technology and use patterns upon energy l evels . Perhaps most importantly, it indicates the practical basis for changes in land use, transportation, and supplemE:ntal energy technologies necessary to effect reduction s in energy consumption . 2 .5 .5 DIRECTION OF MUNICIPAL PROGRAMS REGARDING ENERGY SUPPLY AND DEMAND Municipal policy regard i ng en e rgy conservation relative t o urban form sho u ld focus on the general program ar eas of land use and transportation. As described, i mportant relationships e xi st between the patterns and densities of land us e s, and transportation patterns and d e nsities . Even modest density incre ases promote the use of more efficient transportation modes and building construction and site desi gn methods . Because of the close tie between land use and transportation patterns, t he associated policy and program directions must be mutually support ing. 2 .5.6 LAND USE PATTERNS: DIRECTIONS AND POLICIES A variety of mech ani sms exis t witl1 which land use forms can be guided t oward more e fficient energy consump- tion patterns. Included as factors are t he following : • Creating higher densities, • Combining land uses within geographic areas, • Utilizing more effective buil d i ng layout, orientation and landscaping, and 50 • Applying effective location and density patterns . These mechanisms are described at length in the report, Energy Element: Comprehensive Plan Revision. The creation of higher urban densities is an essential strategy for energy reduction . The common wall area and reduc- tion of apertures in multi-family structures combine to produce considerable space heat savings . This reduc- tion, plus those caused by the more efficient use of public utilities and transit systems, produce economies in energy utiliz ation not afforded by urban forms with predominantly single-family detached dwellings. Ap- proaches used to achieve higher densities can involve the use of higher density zoning, modification of height restrictions, reduction of lot si z e requirements, and amendment of zoning ordinances to allow the vertical mi xing of uses in structures . These techniques foster higher densities th r ough either changes in land patterns, the allowance of taller build- ings within zones, or the ability to increase densities through increased fle xibility in site design. All of these methods are appropriate to Anchorage, and specific recommendations regarding these use s are contained in the Energy Element: Comprehensive Plan Technical Report . The recommendation to increase urban densi- ties is consistent with desired land policies, and both improved flexibility in site design and building siting are essential to the effective use of our remaining urban lands . Changes in building layout, building orientation, and site landscaping are also productive in creating conditions for the more effective use of urban land and public facilities. Appropriate techniques include: the use of bonus points, flexible and cluster z oning, revised site landscaping requirements, and the use of special per- mits to allow for the flexible orientation of structures on lots . Cluster zoning, which allows for the concentration of structures in particular areas and for the preservation of other uses (primarily open space) in environmentally sensitive areas, can be applied to create development patterns that minimize the need for public facilities. Flex- ibl e and bonus point z oning provide similar benefits and can be tailored to provide density bonuses to develop- ers for specified site improvements. The use of these strategies is recommended, and is generally consistent with other Municipal policies to improve site develop- ment practices and reduce private development costs. A final set of strategies involves the location and density of development, and the methods used to guide and influence those patterns . Traditional ways of influencing growth have included the programming of major public facilities, the use of special forms of zo nin g, and the use of comprehensive plans to guide the placement of facili- ties . This orientation should be continued and extended to include the processes of land guidance explained subsequently in the Plan. Although these processes are la rgely related to cost and urban growth considerations, they are also intended to be instrumental in energy conservation and energy management. The rationale for their use should also originate from the need to effec- tively utilize our energy resources. 2.5. 7 TRANSPORTATION RELATED IMPROVEMENTS AND ENERGY CONSERVATION PROGRAMS Even modest changes in land densities have a significant affect on the effectiveness of transit in reducing overall trip-making. The importance of transportation to energy management centers on the consumption of petroleum by private, single-occupant vehicles. Fully 86 percent of all available petroleum products are used for automo- bile and truck transportation in Anchorage . Energy man - agement policies must be concerned with two aspects of the transportation system: the development of a more effective mass transit system and the preparation of strategies to be used in the event of an energy crisis . Attempts to reduce transportation energy use must concentrate on the more aggressive development of the transit system . Less than two percent of all person-trips are made currently by this mode, although there has been a considerable increase in transit usage over the last three years . The reasons for this ridership increase include the increasing cost of gasoline and the conven- ience of transit. Municipal policy, as expressed in the various Anchorage Metropolitan Area Transportation Study reports, is to expand the mass transit system to the maximum extent practical. The attainment of the ten percent modal split rate, by the year 2000, will involve major changes in lifestyle and travel-making behavior, a major expenditure of funds for the purchase of vehicles, as well as substantial increases in the operating costs of transit. The management of the transportation system for energy conservation purposes also involves energy crisis and contingency planning. These analyses are designed to prepare for sudden reductions in energy supplies and for continued high energy costs . They are also intended to result in an overall reduction in fuel consumption and in the increased use of more energy efficient transpor- tation forms . Since the exact date of a future energy shortage cannot be predicted, it is essential that those strategies which require a long lead time for implemen- tation or that should be in effect at the onset of an energ~ shortage, be initiated as soon as possible. These strategies are identified in the Energy Crisis Contingency Plan, prepared by the Anchorage Metropolitan Area Transportation Study. This plan identifies measures that can be utilized at various levels of energy shortfall, or deficit. They involve varying levels of restrictiveness, depending upon the significance of the energy shortfall condition . Because many of these programs are only effective--and are only required--in the event of such shortfall conditions, Municipal policy focuses on the development of strategies to meet probable worse case energy reductions . These strategies augment a continu- ing energy conservation program. The latter expresses Municipal policy to ensure the inclusion of energy con- siderations in traffic engineering, highway, and transit projects, and to promote the more aggressive use of paratransit resources, of both the public and private sectors. 2.5.8 ENERGY GOALS, POLICIES, AND OBJECTIVES The goals, objectives and policies rela t ing to energy management are derived from the various studies and plans prepared by the Municipality relating to energy crisis /contingency planning and energy conservation. They are identified at length in Table 2-3 . These programs must be viewed as a starting point for energy manage- ment planning and as an expression of the general direc- tion to be followed by the Municipality in developing programs to minimize, or make more efficient, energy use . Although a series of program areas are identified which specify major activities that should result in energy use reductions, perhaps the most important recommen- dation concerns the need for an overall energy man- agement plan. This plan should focus on the need to properly inventory and analyze energy patterns, and upon the development of a comprehensive set of strategies designed to deal with a full range of human activities involving energy use. 51 Comprehensive Plan Element or Sub-Element Energy 52 TABLE '2·5 GOALS, POLICIES, OBJECTIVES: ENERGY Goals To integrate energy consideration into all private and public decision-making functions and operations, and minimize the economic impacts of energy supply and demand. To manage Municipal energy use, establish e n ergy-efficient operating and maintenance procedures for government buildings, vehicles, parks and recreation facilities and outdoor lighting. To establish a community education and out- reach program to maximize economic oppor- tunities and minimize economic hardship. Long Term Objectives Encourage and facilitate the development of va- cant and out-moded buildings and sites which are currently served by utility and transportation systems. Increase density allowances on such par- cels where appropriate. Maximize development options along major transportation routes, especially those incor- porating public transit systems. Encourage increased densities and clustered development where cen- tralized energy systems are proposed. Discourage major isolated and free-standing office, education and public service facilities not easily accessible by public transit. Medium density and mid- rise multi-family develop- ments may be permitted adjacent to areas of high intensity employment or person use, such as in- dustrial areas, schools and colleges, and high density commerical units. Short Term Objectives Establish minimum perfor- mance standards for structural heat losses and gains, lighting, interior and exterior, and heating ventilation air-condition- ing systems for new buildings. Design and build new Municipal/public build- ings as exemplary struc- tures to demonstrate the feasiblity of low energy use and natural climate modification techniques. Develop energy conser- vation measures for pub- lic facilites to reduce operational costs and encourage private sector participation in conserva- tion and non-petroleum cogeneration measures. Refine the AMATS Energy Crisis and Contingency Plan to develop neces- sary energy crisis manage- ment programs for the transportation system and continue current energy conservation programs. Policies Land allocation and development patterns should permit the greatest possible current and future use of alternate energy sources for space heating and cooling . The Municipality shall encourage development that takes advantage of natural conditions and utilizes renewable energy supplies, to minimize non-renewable and overall energy consumption. The Municipality shall examine methods of ex- panding existing residential, commercial, and industrial energy conservation programs. The Municipality shall encourage medium and high density residential uses, balanced with other planning policies, to maximize the efficient use of all forms of energy. Commercial, residential, and recreational land uses should be integrated in order to reduce travel distances, optimize the reuse of waste heat, and permit on-site energy generation, as practicable. Continue to encourage the cooperation and communication between the public, utilities, and the various levels of government concerning energy-related issues . Encourage Municipal and State efforts to promote energy conservation in such areas as building codes, the development of renewable sources of energy, and the estab- lishment of equitable energy allocation systems. Comprehensive Plan Element or Sub-Element TABLE 2-5 GOALS, POLICIES, OBJECTIVES: ENERGY COMPONENT Goals Long Term Objectives Senior citizen housing should be located near shopping, personal ser- vices, recreation and cultural centers, with easy access to public trans- portation and small vehicle circulation systems. Medium density residen- tial development shall be encouraged near neigh- borhood service centers. Encourage Neighborhood and commercial uses in centers on major automobile and transit routes. Short Term Objectives Develop a new facility conservation program to preclude the expensive retrofit of energy conser- vation equipment at a future time . Continue and expand the joint State-Municipal Transportation Conserva- tion Program . Intended to reduce single occupant vehicle work trips, this program shall be de- signed to coordinate the areawide alternative modes program . Prepare and implement an integrated Energy Management Plan for the Municipality that provides an overall strategy to community energy con- servation, energy crisis pla n ning, and energy demand planning . Policies The Municipality shall requ ire transit waiting stations and small vehic:le parking facilities at all large public and private high activity centers (such as shopping, recreational, social and governmental centers). The use of mass transit and alternative trans- portation systems shall be encouraged as a major means of reducing energy consumption . Efficiently manage the public and private rights- of-way to permit full utilization and coordination of the circulation and t r ansportation facilities and to maximize passenger and freight miles traveled per unit of energy consumed in a manner consistent with safety and convenience. Medium to high density residential development shall be encouraged at the periphery of the Central Business · District, along primary transit routes and near major transit stations . 53 54 3.1 URBAN DEVELOPMENT: PATTERN AND PROCESS This section of the Comprehensive Plan identifies the relationship between the land use, public facility, and urban development processes that affect the patterns of urban development. It is important to understand that the Comprehensive Plan deals not only with the patterns of development, but with the processes that affect land development over time as well . This latter aspect is par- ticularly critical given the dynamic nature of the Anchor- age economy. The ex isting land use and density patterns reflect the way in which people have organized space for recreation, living, and productive activities. These activities tend to recur, and they exhibit unique physical and spatial quali- ties. Because of this uniqueness, land use patterns tend to be segregated into geographically distinct areas. Cer- tain uses prefer particular locations for given activities . This reflects the capability of the site to accommodate the activity as well as the tendency for certain functions to locate in particular locations Land uses tend to be largely organized on an economic basis, generally to minimize travel costs and maximize market values, but they also reflect social and cultural forces . From a plan- ning standpoint, this last area of concern is critical, since it reflects values that are often obscured by the overrid- ing market forces . The Comprehensive Plan maps express the way in which the community wishes to develop over time and space according to certain developmental goals. These pat- terns of land use and residential densities attempt to accomplish the following objectives of urban planning, which are considered to be either functionally or eco- nomically important: • The ability to provide a ma x imum interaction of human and economic activities . This is critical since all activities are interrelated, but are separated by space . • The opportunity to minimize disruptions between activities so that social and environmental values are preserved. • The ability to properly locate public facility systems. A close interation exists between land uses and the pub- CHAPTER THREE URBAN DEVELOPMENT: PATTERNS AND PROCESS lie facilities required to support those uses. The careful provision of urban services minimizes environmental dis- ruption; and requires a smaller expenditure of public funds. Although the need exists to properly plan land use pat- terns and densities for future conditions, land devel- opment is a dynamic, changing process. Ma r ket forces and community objectives interact in differe nt ways and at different times, over space. Urban patterns tend to change over time, particularly in areas of vacant land or lands needing redevelopment. It is as important to plan for the guidance of these forces as it is to identify the desirable consequences. To reflect this dynamic per- spective, planning theory has evolved to include the concept of land guidance systems . These systems are intended to guide and /or regulate the pattern, timing, and densities of land uses as th ey evolved over a period of time . This Plan includes such a component. It largely focuses on the timing aspect of land development. This chapter describes these two processes : that of organizing land uses and the associated process of influencing these forces over time and space. It is essen- tial to understand the interaction of these elements, and the land use maps should be viewed as an expression of the application of these guidance mechanisms over the next 20 years . The maps are also designed to represent desired future land use patterns, not necessarily desired, near-term patterns . The Short-Range Urban Develop- ment Plan, proposed in the Implementation Chapter, is intended to deal with land development patterns over the next 6-10 years . 55 3.2 LAND USE ELEMENT The purpose o f th e Land Use Plan , w ith its associated Residential Intensity Map, is to : indicate how land uses are to be organized over space, prov ide perspective on the relation ship between these activities, and relate activity patterns to f acility p r ogramming and systems . The land use patterns identif ied in Map 3-1 are intended to resolve a series of sign ificant issues as sociated with the development and use of land. For this reason, the depicted land patterns, plus the land policies associated with that type of land, re present a resolution of the competin g uses for land . Certain of the issues intended to be resolved, for which Municipal policy has been established in the revis i on of the Comprehensive Plan , include the follo w inq : • Location of commercial activity. The Plan specifies a strong orientation toward the development of mutual ly complementary Downtown and Midtown areas, with supporti ng comm u nity commercial centers in east, south, and west A n chor ag e . • Location of i n dustrial activity. The Plan ex presses Municipal policy t o support such development and to locate industrial growth in the Port-Ship Creek industrial area, at the In t ernational Airport and Merrill Field, and along the Alaska Railroa d in central and southern Ancho rage . • Identification of the preferred mix of single-and multi- family housing. The Plan designates a strong orientation toward the dev elopment of multi-family housing in the more central ar eas of the community, particularly Mul- doon, Fai rview, Mountain View and Spenard . This orien- tation reflects the impact o f private market forces and the changes in lifestyle now occurring in the community . At the same time, the Plan recognizes the need to improve buildin g and sit e design p r actices, provide open space, and maintain the integrity of traditional single-family communities . Th is last asp e ct is especially critical and is reflected in the need to apply buffering policies between residential patterns of markedly differ- ent densities. • Identification of appropriate location and density of residential development. The land use policies repre- sent an attempt to balance the needs for additional 56 multi-family housing with the need to provide as much single-family housing as practicable. Multi-family housing is primarily intended to occur in areas currently zoned for multi-family use, which are either vacant and adjacent to major open space resources, or have potential for redevelopment to multi-family densities . Traditional single-family development (subdivision type densities with three to five dwelling units per acre ) is also encour- aged, particularly in southern Anchorage--in portions of western Sand Lake near Kincaid Park, The Abbett- O 'Malley and Lake Otis communities, and in sections of Campbeii-Kiatt. Rural low density single-family develop- ment is intended to continue in the other portions of the Hillside . • Identification of the need for and the location of public facilities . The land use patterns identified herein provide the basis for the number, type, and phasing of public facilities to be provided by the Municipality within the foreseeable future. The densities given in the Resi- dential Intensity Map are further intended to guide the programming of facilities to serve residenti al uses in the Municipal Capital Improvement Program. 3 .2.1 PROCESS OF LAND USE PLAN DEVELOPMENT The land patterns and use densities identified in Map 3-1 reflect the results of a comprehensive analytic process.

It was also strongly influenced by community values and attitudes. Because the land uses and residential intensities identi- fied in the Plan Map are derived from an economic balancing of land demand with land supply1 changes to these patterns must be carefully considered . If changes occur1 the patterns of uses and densities must be read- justed to reflect the effects of this change on other parts of the community. For this reason1 it will be necessary for the Plan to be revised periodically. This aspect of plan implementation will be discussed more fully in Chapter Four. The Plan development process involved the following major steps: • Land inventory. The land use inventory identified the amount and type of developed land b y geographic area within the Anchorage Bowl. It also identified developed land uses by zoning category. In addition/ the inventory specified the amount of remaining vacant land1 by small geographic area1 according to existing zoning classifica- tions . The inventory provided the starting point for the distribution of land uses and for the identifi cation of areas likely to accommodate future urban growth. • Demand projections of residential and commercial- industrial lands. The demand projections of residential and commercial-industrial land were based upon dwel- ling unit and employment forecasts1 and upon land ratios between land requirements and activity types . Demand projections were derived from State econometric fore- casts stepped down to the Anchorage metropolitan region . These population and employment estimates were translated into land requirements for residential1 industrial1 and commercial land . In turn1 the areawide land requirements were stepped down to smaller geo- graphic regions in order to identify land needs for zonin g and land use planning. These projections represent the demand side of the planning process1 whereas the inventory represents the supply component. • Allocation and Reallocation Process: Land Demand/ Supply . The allocation process is repetitive1 involving the balancing of land supply with land demand for each of the various uses of commercial1 industrial/ and resi- dential land . It inv olv es the initial allocation of demand to particular geographic areas and1 later1 tlle allocation of that portion of the land demand to other geographic areas that cannot be accommodated under the first allocation of demand. The results of the allocation and reallocation processes are a balancing of land demand and land supply for the design year (year 2000 ). The Plan maps represent a balance between the various land uses1 and changes to thi s distribution will require a resorting of the depicted land supply/land demand allocations. 3.2.2 PLAN MAP: DEFINITIONS Effect of Directory Provisions The provisions of this Ordinance are not intended to be self-executing1 unless so spec ified by their terms. All provisions which are not self-executing are deemed to be directive and advisory . Directive and advisory provi- sions are intended to establish a continuity of govern- mental policy that are to be used as guidelines for future actions of the Munici pal gov ernment. The Municipality shall 1 when appropriate1 cons ider adviso ry provisions and shall take positive actio n toward meeting directives within a reasonable time . Land Use Classification System A vital part of any Compr ehensive Plan is the develop- ment of a land use classifi c ation sys tem upon which 61 future zoning will be based. The principal objective of such a classification system is to provide a rational and consistent foundation, which will guide the entire land use regulation system. Previous zoning changes have resulted in a patchwork pattern of various types and densities of land uses . Many incompatible land uses presently ex ist. The Land Use Classification System w i ll help eliminate future incon- sistencies . • Purposes of the regulatory system: I. Provide a balanced, compatible land use mix, including a range and placement of land use activities deemed necessary to the community well-being; 2 . Separate incompatible uses and minimize conflict between land uses ; 3 . Provide appropriate land use allocations, by category, in keeping with a realistic ass essment of areawide and localized community needs; 4. Assure that the functional classification of land a c hieves stated community purposes; 5. Ensure the continued physical, social and economic vitality of each community within the Municipality; 6. Provide incentives for reinvestment by the private sector to achieve stated community objectives; and 7 . Accommodate changing li f e styles, technology and economic conditions. • Form The land use classification system establishes functional land use categories. These categories are physically grouped in a manner which achieves complementary relationships within and between category. The Plan Map 3-1 graphically depicts the classification system and provides guidelines regarding the scale and intensity of development. 62 Residential: This classification would apply to those areas which are substantially developed for residential pur- poses and which are expected to remain that way within the time frame o f the Comprehensive Plan .lt also applies to those areas that are now vacant but are best suited to future residential development. Residential land use density ranges are applied to each community, which generally indicate the number of residential units achievable in a general location. The actual achievable use of a given site will be further defined by the residen- tial zoning, the nature of and adjacency by other uses, the availability of public services and facilities , and envir- onmental considerations. Future land regulations would be guided by the designated intensities of the Plan Map. This classification should have very little effect on existing residential areas, except where redevelopment is occur- ring or is anticipated to occur. In these instances, it would serve to reinforce or enhance the quality and character of the residential community and of those land use policies contained herein. Commercial : This classification would apply to those areas which are substantially developed for commercial purposes and which are expected to remain that way within the planning period . It also applies to those areas that are now vacant but are best suited to future com- mercial development. The actual achievable use and development criteria for any given site would be further defined by the commercial zoning the nature of and adjacency of other uses, public services and facility avail- ability, and environmental considerations . The location of all new neighborhood business areas are not de- picted on the land use classifications map, because it is impossible to determine the extent and location of these areas at this time . It is anticipated that when requests for neighborhood business zoning are submit- ted in locations not depicted on the map, such requests would be favorably considered, only if a need is shown, and if the policies for the establishment of business areas which are part of this plan are followed. Industrial: This classification would apply to those areas which are substantially developed for industrial pur- poses and which are expected to remain that way during the planning period. It also applies to those areas that are now vacant but are best suited to future industrial development. The actual achievable use and develop- ment criteria for any given site would be further defined by specific industrial zoning the adequacy of public services and facilities, environmental considerations, and existing or new performance standards. Commercial-Industrial : This classification would apply to those which are substantially developed for industrial- commercial purposes and which are expected to remain that way during the planning period. It also applies to those areas that are now vacant but are best suited to future commercial-industrial development. The actual achievable use and development criteria for any given site would be further defined by the specific zoning, the adequacy and availability of public facilities, and envir- onmental considerations . This classification reflects the tendency for compatible and linked industrial-com- mercial to locate within similar areas, and recognizes the inter-dependency of these uses . It also stresses the need to develop such uses, to the extent practicable, within planned commercial-industrial tracts along major arte- rials . Public Lands and Institutions: This classification would apply to all existing active uses of this type where devel- opment plans have been completed and adopted, or where it is reasonable to expect the use of recently acquired state lands for some public purposes. It would not apply to such lands where the permanent use is yet to be determined. • Residential Densities To further define the land classification system, density ceilings are established for each residential classification . These ceilings serve to define the general level of desired development. They are scaled according to factors such as proximity to services, employment, and transporta- tion . Thus, land next to the Downtown Business District could accommodate greater density uses than outlying land not located near such an employment center. Both initial development, and the redevelopment of existing uses, are to be subject to these density criteria. Areas designated for future residential land uses are also to be subject to these density criteria . See Map 3-2 . These densities are meant to express gross density levels; as such, they provide a general indication of total number of dwelling units in a contiguous geographic area for the purposes of facility planning and as an indication of the overall distribution of population and of desired housing type (s). In certain areas, especially in wetland and marginal soil environments, selected densities may exceed the gross density ranges providing, however, that assurances are made for internal circula- tion, sufficient open space, and buffering. When the buffering and open space areas are included with the developed area, the overall density should be within the gross density range. Land Use Goals and Objectives The previous discussion focused on the infrastruc- ture requirements and the goals / objectives required for the maintenance of the other functional systems . :;:;· Goals and objectives are identified for the land use component in Table 3-1 . They are specified by geo- graphic area and by type of land use . These goals / objective s repre s ent "more specific statements as to the manner in which the community" wishes to develop, to organize the predominant land uses within the community. They constitute a further explanation of the spatial patterns expressed in the Plan Map, and are, there- fore, a more ex plicit defini- tion of those planning criteria to be used in site planning, subdivision, and zoning/rezoning case re- views. They are also to be followed in the evaluation of changes to the Plan Map of this Comprehensive Plan. 63 Comprehensive Plan Element or Sub-Element Element: Land Use Sub-Element : Residential 64 TABLE 3-1 GOALS, POLICIES, OBJECTIVES: LAND PATTERNS Goals To develop an enforceable land use plan for the social and economic needs of the com- munity, consistent with the natural characteris- tics of the area .

It recognizes the dynamic nature of urban growth and the need to respond to basic economic forces. It also ackowledges the very real impact of public decisions upon urban form and the need to effectively organize these decisions. The land guidance system is intended to influence the patterns of urban forces that operate over time in order that the spatial patterns and densities given in the Comprehen- sive Plan can be fully realized. The types of control measures that may be applied under community growth management systems range greatly in both diversity and emphasis. They vary from the use of conventional subdivision and zoning controls to the more innovative forms of urban services provision and preferential land taxation. Certain of the controls tend to be prescriptive and are expressed in a regulatory form; others are more flexible in their application and are oriented toward providing sufficient incentives to redirect normal market forces. The types of methods that are used include administrative, planning, public facility, and timing techniques. The range and types of controls are identified at length in the report, Municipal Land Management System. The land guidance system recom- mended in the Comprehensive Plan focuses upon the use of incentives and flexible land guidance mechanisms The intent is to strengthen the current set of regulatory controls dealing with land development, and to orient them increasingly to time and spatial processes. The types of controls that are selected and later applied are also geared to particular land development patterns. Certain of the more inflexible regulatory mechanisms are geared to the development of controlled forms of urban growth. The approach recommended herein reflects and reinforces the moderate infilling developmental strategy expressed in the Alternative Land Use Study, and in the Plan Map Technical analyses found that the more restrictive land guidance mechanisms are only necessary under very concentrated growth patterns. Such patterns were not determined to be appropriate at this time. 69 3.3.1 RECOMMENDED LAND GUIDANCE APPROACH The land guidance system recommended here emphas- izes the use of incentive mechanisms, and is geared toward the attainment of moderate levels of in-filling within areas of vacant land either served or about to be served, by water and sewerage systems. This approach provides the timing component necessary to achieve the land use patterns of the Comprehensive Plan. See Map 3-3. It should be emphasized that the areas depicted on this map are intended to represent the major areas of facility expansion in future years. Certain smaller acreages may not be depicted, because of cartographic scale. In these instances, the adjacent identifiable service timing areas should be used to indicated the appropriate phasing period. Larger, vacant areas unidentified on this map are not intended to receive organized sewerage and water services. These are intended to remain as rural, low- density of vacant areas, and are so identified, in detail, in the Hillside Wastewater Management Plan and Wetlands Management Plan, respectively. Of course, the other services of (but not limited to) fire, police, and schools must be provided to the developing rural areas of the Anchorage Bowl as population increases. It is expected that Stuckagain Heights will not require organized water and sewerage services. Phasing strategies for the southwestern Campbeii-Kiatt Bog will depend upon the outcome of the on-going wetlands study. Urban development is intended to occur in an orderly, sequential fashion from the current urban periphery. In this way, public facilities can be economically extended and fully utilized to design capacities. It will also make possible the more efficient provision of such urban ser- vices as transportation, social services, and health and educational facilities. The principal characteristics of this strategy are the following: • Redevelopment of areas within the Mountain View, Downtown, and F·airview communities to realize higher multi-family densities. The development of these densi- ties will serve to: 1) provide sufficient multi-family hous- ing stock for the growing multi-family market, and 2) insure that certain environmentally sensitive areas in south Anchorage are preserved and/or conserved in their natural state or at conditions close to that state. • Preservation and/or conservation of certain critical areas in the south Anchorage area. Certain ofthese areas include wetlands, coastal marshlands, and critical habi- tat areas for wildlife. Development at higher urban densi- ties in the more central areas of Anchordge will allow certain of these environmental areas to be retained in their natural state; this will also achieve other environ- mental objectives as well as avoid high site preparation costs in marginal soil areas with excessive peat over- burdens. • Increasing concentration of development in the south Anchorage area. This region contains most of the deve- lopable vacant land in the Anchorage Bowl. The growth of this area is to be separated into near-term and far- term planning periods. Near-Term: Within 1-10 year period, facility develop- ment should occur within the large, remaining vacant tracts of land designated for development in the Land Use Map and Residential Density Map. To the extent practicable, services should be provided as a unit during the same phasing period in normal design sequence. Water, sewerage, storm drainage and the other major infrastructure elements should be provided initially. Demand responsive services, as schools and parks, should be planned prior to infrastructure placement but provided in close response to demand. Within this time period, major new water, storm drain- age, and sewerage facilities should be concentrated within the following areas of south Anchorage: portions of Sand Lake west of' Sand Lake Road, in the Abbott Loop area between the New Seward Highway and the Campbell Airstrip Tract; in the area of Campbeii/Taku and Sand Lake adjacent to the Minnesota Bypass Corri- dor, except immediately adjacent to Connor's Lake; in the Campbeii/Kiatt area adjacent to the Minnesota Drive-Victor Road extension projects north of O'Malley Road (extended), and the western portions of the Hill- side identified in the Hillside Wastewater Mangement Plan. Development in these areas is to occur at higher urban densities, as identified in the plan maps and, in the areas of wetland and other environmentally sensitive areas, preferably under versatile design approaches involving either flexible or cluster zoning and Planning Unit Development design. Environmentally sensitive and important open space resources, identified in the Plan Map, are to be retained in or near their natural state, to the extent practicable. The provision of other public services and facilities in the aforementioned areas, and in the :other parts of the Anchorage Bowl, should occur consistent with pro- jected increases in demographic and economic growth. Far-term: Facility provision should primarily involve an in-filling process of the remaining vacant lands not pro- vided services during the near-term period. Organized sewerage services are not to be provided in areas desig- nated as rural, low-density in the Residential Intensity Map. 3.3.2 PACKAGING OF LAND AND G.UIDANCE STRATEGIES Land guidance/maraagement strategies tend to be mutually reinforcing, and are structured to achieve par- ticular patterns and densities of land uses. Both these strategies and their associated policies are tied to the ways that the community wishes to manage and develop urban land. The strategies identified herein create the bridge be- tween the private and public sectors in the urban growth process. They focus on mechanisms designed to be flexible in approach, and are geared to a strengthen- ing of current regulatory systems. In order to be effective, the conceptual basis of growth management planning must be transferred to a particu- lar set of planning and programming actions. In general, the Municipal growth management system is organized about four major strategy areas: • Timing and Phasing Strategies-General The Comprehensive Plan is intended to provide the main rationale for the use of growth management mecha- nisms. This Plan specifies that the implementation tools used to stage growth, including the Capital Improvement Program and U~ban Development Plan, are to emphasize the sequential provision of services at the periphery of the existing, built-up areas. The Plan also shall establish the timing of facility provision and provide the basis for the sizing and siting of public services and facilities. • Timing and Phasing Strategies-Specific The land management system recommended herein includes a facility timing component. The phasing of growth in the South Anchorage area-specifically-the areas of the western Hillside, Campbeii-Kiatt, Abbott Loop and Campbeii-Taku-is recommended within the next 10 yearsi thereafter services should be provided in an infilling manner. It is also recommended that the sewerage system be used as the key to manage the rate and location of development. This system is wholly within Municipal control and exerts extensive influence over land patterns and the rates of land development. • Site Design Improvements These strategies are designed to improve the quality of development and increase the number and range of facilities to be provided within developing areas. Site design techniques include the use of flexible/cluster zoning, the application of land banking techniques, the use of the "master plan" concept in site reivew, and the requirement for the evaluation of secondary impacts and mitigating design procedures in subdivision plat review. These procedures do not greatly impact the timing and location of growth, but are effective in pro- ducing better site design. This is achieved by allowing increased flexibility in design and preserving certain crit- ical environmental areas from development, or by mit- igating the impacts of such development. • Strategies Involving Improvements to Administrative Process The growth management system incorporates recom- mendations designed to improve the permitting process for private urban development projects. These recom- mendations are designed to enhance site desi.gn and the rapidity of development. The Municipal Growth Management System is intended to provide for public involvement in land use manage- ment decision making while providing clear and defini- tive guidance to the development process. The proce- dures recommended herein concentrate upon phasing and timing strategies. They also include techniques to improve the quality of site design and increase the number of needed urban services when required. Together these approaches should provide a mecha- nism whereby development can be managed as to its location and density in a more effective way than has previously been the case. The goals and objectives identified in Table 3-2 indicate how development should occur as a process over time and space. In a sense, then, they represent the dynamic aspect of land use policies. They are intended to provide guidance to decision-making on the timing and rate of development, as well as on the location of growth. Finally, they specify which mechanisms are to be utilized, and how these mechanisms are to be applied to achieve desired development patterns. 70 lJ 0 n 0 0 0 0 0 0 0 0 0 0 0 n lJ Facility Phasing Municipality of Anchorage Anchorage Comprehensive Development Plan 1 Kilometers 2 M iles 0 ELMENDORF AIR FORCE BASE ' ' ' ·-~--;-' : ' ' ---"' I ,...1 r -' ' I I I : CAMPBELL : i FIELD ,...J ' -' ' •' L-'-------~ :I: u a: iii ClnAn ROAD w 0 iii ... ... l: ~ 0 "' 0 a: ~ " it .... a: 0 "- I I I I I ' I I I I I I r------------1 ' I [ u u u Comprehensive Plan Element or Sub-Element Ur ban Land Ma n agement Process TABLE 3-2 GOALS, POLICIES, OBJECTIVES: LAND MANAGEMENT PROCESS Goals To develop the community in an orderly, se - quential w ay to achieve a moderate i n-fi lling o f vacant urban lands served or about to be served by p u b li c facilities.

[ [ 0 c c [ 0 0 0 c 0 0 0 4.1 INTRODUCTION The purpose of comprehensive planning is, of course, to affect the patterns and densities of land development. The traditional planning focus has been on physical development patterns, as identified 20-25 years in the future. But increasingly, planning has been concerned with the means by which development decisions can be influenced over time in order to manage the process of urban growth to achieve desired patterns of land use . This section identifies the implementation measures which will carry out the recommendations of the Com- prehensive Plan , as well as identify the relationship intended to exist between this Plan and other programs and activities. The Plan should not be viewed as a device for limiting the further development of the Anchorage Bowl, but, rather, as a mechanism to ensure its enhance- ment as they are continues to grow. Both the design of the implementation measures and the adoption of this Plan will depend heavily upon the involvement and sup- port of the Anchorage community. 4.2 LAND USE IMPLEMENTATION MECH- ANISMS: LAND USE PATTERNS The mechanisms used to achieve the patterns and den- sities of land uses given in the Comprehensive Plan focus upon the traditional methods of subdivision and zoning review, as well as the newer forms of innovative zoning and performance controls that strongly affect land development. These patterns are also controlled, to a very large degree, b y the strategies associated with the land guidance system described in Chapter Three. 4.2.1 THE PLAN MAP The Plan Map is adopted to supplement and explain the written text of this Plan and to establish a rational guide for the future application of land use regulations. • Land Use Classification Map Form and Purpose: The Land Use Classification Map iden- tifies those areas which, on the basis of the entire Com- prehensive Plan, are best suited for the functional classi- fications indicated. The Map further identifies those ar eas, regardless of classification, which should be gov- erned by more flexible regulation . The functional cate- gories neither affect current zoning regulations nor place additional regulations on specific property. Further land use regulation decisio ns such as rezoning, subd ivision and special exceptions, must conform to the indicated functional categories in the absence of excep- tional circumstances. Exceptio ns could be recognized where existing uses are co mpatibly integrated into the area or where future us es could comply as compatible land uses b y meeting appropriate standards pertaining to access, noise, landscaping, screening, structural, or other improvements required by circumstances (see Map 3-1). CHAPTER FOUR PLAN IMPLEMENTATION • Residential Intensity Map Form and Purpose : The Residential Land Use Intensity Map depicts generally desirable densities or intensities of future residential development. Th e Reside ntial Inten- sity Map will not affect current zoning regulations nor will it place additional regulations on specific property. Future land use decisions must conform to the indicated intensity except in those circumstances where a greater specific intensity would not alter the plan for the area . Unless there is a clear and overriding benefit to the immediate neighborhood, densities l ower than those indicated on the Plan Map are to be stro ngly discour- aged since they affect the implied balanced distribution of residential, commercial, and industrial land use s given in Map 3-1. 75 Development at su c h l ower densities must establish a strong factual basis for such change an d must demon- strate that no re3sonable alternative exists to the pro- posed action . Somewhat greater intensity may be pro- vided through p l anned un it developments, the use of the proposed cluster or flexible use zoning ordinances, o r near establ ish ed high-density nodes or in areas im- mediately adjacent to suc h nodes where the rezoning process determin es that these densities are consistent with the overall intent of concentrated housing at a focal location. Likewise, greater density may be suitable around neighborh ood shopping centers or along prin- cipal transit corr idors. (See Map 3.2) The Comprehensive Plan Map provides guidelines for land use decisions. Because the Map represents a sum- mary of a ll the written data and policies o utlined in the Comprehensive Plan report, it is necessari ly generalized. Since generalization is requisite, the exact boundari es are subject to interpretation. Areas c learly within any particular classification should be treated as indicated. Areas at or near the boun daries may be analyzed under either or both classifications, utilizing the goals and objecti ves contained in the text, provided that the imprecision of the boundaries is not used as a basis for cumulative encroachment. Ultimately, these Compre- hensive Plan Maps must be precisely defined and i mple- mented through l and use regulation, ordinances, and the preparation of sub-area lan d use plans. 4.3 ADOPTION OF CERTAIN ADDITIONAL ELEMENTS AS PART OF THE COMPRE- HENSIVE DEVELOPMENT PLAN Certain studies are essential to imple me ntation of the Comprehensive Plan , since they both affect and support the location and densities of devel opment. The fo ll ow- ing studi es are adopted by reference as part of the Comprehensive De velopment Plan: Coastal Zone Ma n agement Plan Street and Highway Landscape Plan Long Range Element of the Transportation Plan (AMATS) Areawide Trails Plan Water Quality Management Plan Comprehensive Library Services and Facilities Plan Official Streets and Highway Plan Wetlands Management Plan Hillside Wastewater Management Plan 76 These plan elements should be considered as expan- sions of the Comprehensive Development Plan and the Plan Map. 4.4 URBAN DEVELOPMENT PLAN Th e long-range land u se plan has a number of va lid objectives, some of which can only be addressed by resolving general, complex development issues. Certain of these functions include the allocation of land to their more suitable uses; the promotion of economic effi- ciency by coordinating the size and location of public facilities; and the development of a unified, large-sca le urban design. Nonetheless, it is increasingly evident that long-range planning is an inadequate guide to current decisions. Because of this, greater regard must be given to short-term programming and to the impact assess- ment of actions designed to solve present land use problems. Increased attention to the short-range pro- gramming of actions should also enhance the likelihood of achieving the long-range objectives in the 20 to 25 year land use plan. Accordingly, the future Municipal p lannin g program shal l include a short-range 1-6 year land devel opment plan, and, as the basis for the budget process, a one-year plan of improvements. The Urban Development Plan is to concentrate on a program of specific short-term actions to be undertaken in a stated sequence, within stated time limi ts, and by specific units of l ocal government. It is to be based on specific targets or objectives derived from the Compre- hensive Plan and Municipal Land Management System, and is to i nclude an analysis of financial impa ct and feasibility. The Planning Department is to be responsibl e for the development and maintenance of the Urban Development Plan . This Plan shall be reviewed by the Planning Commission and Assembly. 4.5 RELATIONSHIP OF COMPREHENSIVE DEVELOPMENT PLAN TO MAJOR PLANNING PROGRAMS AND ACTIVITIES The Comprehensive Development Plan is supported and implemented by studies and programs that deal with urban services, urban facilities, and the process of urban development. Because these studies are central to plan implementation, the relationships between and among these stud ies are identified below. The intention is to describe the purpose of the individual studies in impl e - menting the Comprehensive Plan and the role that the Plan p l ays in forming the ge neral structure and focus of these studies and programs. 4.5.1 URBAN DEVELOPMENT PLAN The Urban Development Plan is intended to be the short- range component of the Comprehensive Plan. It shall identify the principal areas of urban development, the areas to receive major urban services, and the mechan- isms to be used by the Municipality in guiding urban development over the short term ( 1-6 years ). The Com- prehensive Development Plan is designed to provide the long range focus of the Urban Development Plan (UDP), and it is intended that a strong interrelationship exist between the short-range solutions of the UDP and the long-range strategies of the Comprehensive Develop- ment Plan. 4.5 .2 MUNICIPAL CAPITAL IMPROVEMENT PROGRAM The Municipal Capital Improvement Program shall specify the public faci lities necessary to the i mplementation of the Comprehensive Development Plan. The Capital Im- provement Program (CIP) is also to be directly tied to the Urban Development Plan . The latter identifies the areas to receive urban services by given time periods. The Comprehensive Development Plan is designed to iden- tify the general areas of urban development, and the Capital Improvement Program sha ll schedule those facili- ties and services necessary to the support of l and pat- terns at the times specified in the Urban Development Plan. 4.5.3 MUNICIPAL LAND MANAGEMENT SYSTEM The Municipal Land Management System shall ge nerally specify the areas and time periods for which develop- ment is to be encouraged. This report provides the rationale for the phasing strategies recommended herein and describes in detail the methods to be used in achieving this strategy. The so uth Anchorage area is intended to receive the majority of new services. There shall be both near-term and long-term strategies to the 0 D n J 1 [ c [ RELATIONSHIP BETWEEN FUNCTIONAL PLANS AND COMPREHENSIVE PLAN Environmental Plans Coastal Zone Management Pl an Wetla nds Man agement Pl an Co asta l Access Trai l Pla n Water Quality Management Plan Wetl and M anagement Pl an Hil lside Wastewater Man agement Plan Comprehensive Plan Transportation Long Range Element - Areawide Trails Plans Transp ortat ion - Sys tem Management Ele ment Street & Highway Landscaping Plan I Official Streets and Highway Plan Pub l ic Facili ties Areawide Tra ils Plan Comprehensive Library '-- Service and Fa cilities Plan Areawide Parks -O p en Sp ace Plan Water Supply Study 77 provision of urba n serv ices. The Comprehensive Devel- opment Plan is to provide the overall rationale for the timi ng and devel opment of t hose densi ties t o be achieved at given time periods. Th e land gu i dance sys - tem i dentified in the Munici pa l Land Management Sys- tem shall be compatibl e with t h e timing and urban den- sity rec ommendations containe d herein. Rece nt planning theory has stressed the need to de- velop short-range i mpleme ntati on projects and pro- grams to implement the long-range recommendations of the Co mprehensive Plan . Pre vious com prehensive plan- ning effo rts in other communities, as well as those of A n ch orage, have resu lted i n less than o ptima l near-term so lutions for land uses an d densities because of the long-range o r ie ntatio n of comprehensive plans. Th e pre- vi o usly mentioned short-range me c hanisms, incl u ding the Municipal Land Management System, Urban Devel- opment Pr ogram, an d Municipal Capital Im prove me nt p r ogra m, should have t he effect of, and are i ntende d to p r ovi de, mechani sms to rela t e the Comprehensive Plan to short-range decis i on ma ki ng. Th ese strategies are therefore intended to i mplement, i n a d i rect and clear way, the recommendations of the l o n g-range Compre- hensive Plan . 4.6 PROCEDURAL LAND USE IMPLEMEN· TATION MECHANISMS Ce rtain programs ad min istered b y the Municipality has an important affect upon the p rocesses of urban growth. Included in this type are t he Coastal Zone Management Program and the admi nistration of r ecentl y selected State lands. Be cause o f the ir actual and potential impact, th ei r re la tionship t o the Comprehensive Pl an is de- sc ribed: 4.6.1 COASTAL ZONE MANAGEMENT PLAN Th is program provides a fr amew ork for decision-maki ng w ithin the coasta l zone on both natu ral and manmade fe atures. It is intended that t he l an d use recommenda- tions contained In this Plan are to be an expression o f the p reservation, conserv ation, and utilization areas with i n the developed porti o ns of the A nch orage Bow l and are to represe nt the r eso lution of the zones initiall y i denti- fied as "marg inal" and "confl ict " withi n the Coastal Zone 78 Management boundary. It is further i nte nded that the spatial patterns given i n the Land Use Map and its asso- ci ated goals and polici es are to guide the management of an d d ecision-making process es on lands withi n t he j urisdiction o f the Coastal Zon e Manag ement Plan . 4 .6.2 MUNICIPAL LAND SELECTION The Municipal En titlement A ct prov id es for the se lection of certai n State lands w ithin the corporate bo u ndari es of t he Mun ici pality. The Municipality has f iled upon, and r eceived from the State, various tracts of la nd through- out the Municipality. Much of this la nd re ma ins vaca nt and ava ilable for a vari ety o f potenti al uses. It is intended that the u l t i mate use o f M unicipal selecti on l an d s be consistent with this Plan and oth er approved planning docume nts. To fu rth er such consi stency, the Municipality has devel oped a systematic l and management program w ith th e following key e l ements: • Muni cipality owned la n d s presently required f or spe- cific public uses wi ll be r eserved for such uses in accor- dance with Munic ipal regulations. 4 .6 .3 WETLANDS MANAGEMENT PLAN This Plan designates ar eas of wetlands protection, con- servatio n, and development. It also establis hes the proper mi x and t ype of la n d manageme nt co ntrols to be used in the p rotection or development of these critical envir o nmental areas. It is i nte nded that the land u se and reside ntial i ntensity recommendati ons o f this Plan are t o control the use and mana ge ment of wetlands withi n the Anc horage Bowl. By inference, both the Coasta l Zone and Water Quality Management Plans are to be consist- ent with the land use policies of this Plan to the ext e nt that they relate to wetlands. • Municipally owned la nds requ ir ed for specific, fu- ture public uses will be cla ssified and reserve d for such u ses. ~,~E!!&i~ • Ad d itional la nds wi ll be r eserved, primarily on a r egional basis, for unspeci- fied future public uses . • Lands not requ i red for present or future public use w ill be consid ered for d is p osal, consistent wi th applicabl e lan d u se r egu- lations. Adopted land manage- ment policies and identi- fied land u ses will, to the ma ximum extent pos- sible, fu rther the goal s and objectiives of this Plan . r 0 4.7 LAND USE IMPLEMEN TATI O N: PRO- CESS MECHANISMS As indicated, the success of the community to realize its desired land use patterns will greatly depend upon our ability to guide and manage urban growth. The basis for growth management planning, as recommended in this Plan, is to focus on the strengthening of current land control ordinances, the use of ince ntives to he l p guide growth, and t h rou gh the schedu l ing of sewerage facili - ties . This last compone nt is critical to gu iding the rate, density, and pattern of urban growth. It shall be Munici- pal policy to implement a growth management process of the type given in the Urban Dev elopment Patterns and Process Se ction of this Plan . These mechanisms are des- cribed at length in the Munici p al Land Management Sy stem report. 4.8 PLAN REVIEW PROCESS Th is plan is i ntended to represent a broad policy toward land dev elopment and management within the Anchor- age Bowl. As such, it w as developed around a given set of community attitudes, and demographic data and trends. It is certain that these attitudes and trends will change over time. For this reason it is necessary to estab- lish a process for p lan review and reevaluation . Beca use this review need not nec essari ly result in the co mp l ete revisio n of this Pl an, three l eve l s of review are identified: • Plan Reevaluation. A reevaluation of the major trends and/or policies of the Anchorage Comprehensive Plan must occur five years from the time of its ini tial adoption. If major deviat ions from those anticipated in the init i al Plan are not i dentified, a com plete revision of the Plan is not required . If major discrepancies are noted in this reevaluation, a revision of the Plan is warranted and shall be initiated. • Plan Rev ision. The Plan must be reviewed and revised at least once every ten years, preferably following the decennial Census . • Plan Review. The plan sha ll be reviewed once every two years from its time of adopti on i n order to make it c onsi stent with economic and demographic trends and with recent l and use decisions and adopted studies and plans, and such other decisions as may be appropriate at the time of review. It is intended that the adoption of this Plan will indicate that the abov e processes are to be followe d in study reeva luation in order to ensure that the basis framework for decision-maki ng re mai ns cu rr ent. The ana lytic pro- c ess use d to develop t his Pl an invol ved an inventory of land availability and a forecast of land demand. It identi- fied a potenti ally serious shortfall of res•dential land supply i n the 1990-2000 period. Because of the possible magnitude of this problem, it is recomme nded that future plan reviews critically examine the characteristics of the projected land supply-land demand relationship, to determine if the recommendations con tinued herein remain va l id or should be changed. It is further recom- mended that this review ana lyze additions to the Anch orage Bowl l and supply, to incl ude adjacen t mi litary l ands and lands north of the Kn ik Arm. 79 D 80
