In essence, it is a plan intended to preserve the natural characteristics and amenities of the Tigard Community, while simultaneously providing a sense of integrated community design. As a bonus for this method of planning, a useable network of open spaces for recreation and relaxation is identified and permanently set aside. Growth in any community means a reduction of open space. Across the nation, houses are covering agricultural land, flood plains and wetlands are being filled and built on, and a multitude of unique natural features are being exploited and lost forever. At the same time, growing popula- tions place an increasing premium on the preservation of these same re- sources. The loss of forest lands, scenic views, wildlife habitats, and increasing pollution addes emphasis to the need for preservation and con- servation of our valuable resources. These conflicts between growth and they environment are the result of the several components of urban development competing for the use of our land resources to suit their specific needs and desires. The basic conflict is between the individual land use rights and the broader inte- rest of the entire community. This is a major philosophical question for which there is rising pressure to resolve. Tigard and other local governments throughout the land are confronted with this issue on a daily basis. The solution undoubtedly lies in the recognition of the necessity for maintaining an equitable balance between the government's : desire to protect the public interest and the individuals, business and corporation 's wish to use his land as he 'pleases. 44 44111111 3: y. F s` f This Plan recognizes the value of the natural environment and d attempts to establish the degree of respect due the land. This is accomplished through a process of using nature as the major J guide to land development . In the following plan, nature's processes are used to determine policy direction to insure that continued development will be in harmony with the natural features of the community and in the best interest of all concerned. G The Plan policies are presented in three major sections. The first a section, ENVIRONMENTAL PROTECTION AND PRESERVATION, deals with natural processes (storm water runoff, erosion, etc. ) and subsequent physical limitations (flood plain, steep slopes, soil types, etc. ) . It also sets the framework for the sections two and three. Using environmental criteria, section one establishes construction and location controls for k all types of development. Speicifc areas such as flood plains, steep Slopes and natural habitats are categorized as non-developable and set aside as permanent open space. Section two, ENVIRONMENTAL COMMUNITY DESIGN, augments these controls by offering community design criteria for the purpose of integrating development with the physical features of the area. These criteria are centered primarily on the appearance of a structure and its relationship to topography, natural vegetation and surrounding land uses. The third section, PARKS AND RECREATION, completes the package by formulating policies and standards to guide the development of a system of parks and open spaces aimed at maximizing recreational opportunity and aesthetic benefit to community residents. The open space system r proposed by this Plan was generated by using the landsdesignated (from section one) as environmentally unsound for constructionas its founda :2. tion. The majority of these unbuildable lands are along Fanno Creek and its tributaries and are referred to in the Comprehensive Plan as the Greenway System. In addition, the Greenway is augmented by specif- ic sites selected for their environmental uniqueness (e.g. , attractive- ness, historic value and/or recreational potential) . The individual components of the open space system are to be linked together, for opzinium accessibility, use and enjovment, by means of a network of pedestrian/bike paths. Thus, the total package yields an integrated community design. The design ensures the continuance of natural cycles and enhances the visual attractivesress of the community. Simultaneously, the community bene- fits in several ways: Psychologically, through retention of essential natural features which daily remind the individual of the delicate thread connecting each person's life to the natural order of things; Sociologically, from expanded recreational opportunity allowing diverse community participation in outdoor activites, and through a community design that promotes community identity; Personally, from increased health and safety derived from reduced air pollution (e.g. , natural air purification of trees) and minimized potential for damage to property or loss of human life, caused by natural hazards such as flooding and land slides; And Economically, through efficiencies in supplying public services (police, fire, water) to a unified area, and from an enhanced city image promoting increased property values and attracting new employment in the form of commerce and industry. Z 3. i t F' THE TIGARD COMMUNITY PLANNING AREA The City of Tigard, once a farming community, is now essentially a residential suburb of Portland, It is situated in the southeast portion of Washington County abutting portions of western Clackamas and Multno- mah Counties. However, in order to accommodate expected growth and to give consideration to areas directly influenced by the city, the plan area boundaries were drawn outside the actual city limits (see map p. ) . The plan area is served by three major transportation routes, Pacific Highway, Highway 217 and Interstate 5. Two rail lines also serve the area. PHYSICAL SETTING Tigard is located at the lower end of the Fanno Creek Drainage Basin which empties into the Tualatin River at the city's southern boundary. This location makes flooding a particular community concern which this plan addresses. However, while Fanno Creek poses the threat of periodic flooding, it also offers the natural asset of a relativpl;7 updevelnned a.rnd heavily vegetated meandering course through the center of the community. This feature becomes even more attractive when the tributary streams are added, as they flow between gently rolling hills often covered with significant stands of timber. The major topographic relief in the plan area is in the western portion in the form of Bull and Little Bull Mountains. Elevations within the plan area range from 500 feet near the top of Bull Mountain to 110 feet at the Tualatin River. DEVELOPMENT PATTERN i Since, the early 1950's the community has undergone, at an increasing- ly rapid rate, a transformation from rural to suburban land use. Develop- . 1 i ment was uncontrolled and unplanned until the adoption of the 1971 Tigard 4. Community Plan. The Community Plan was the city 's first attempt to counteract the unsightly strip commercial and disjointed residential sprawl of the 19601s. Fortunately, since the Community Plan, more at- tention has been given to aesthetic design. Nevertheless, Tigard is left with an undesirable scar of strip commercial development along Pacific Highway. Early development also exploited the natural ameni- ties of the community, inefficiently consuming land with little regard for natural processes or recreational space. The land use map (P. ) shows the majority of the commercial activity being centered on Pacific Highway with increasing development along Highway 217 and Hall Boule- vard. The more intensive industrial uses occur west of Interstate 5, along 72nd Avenue and follow the Burlington Northern and Southern Pa- cific railroad tracts. RESIDENTIAL DEVELOPMENT While scattered throughout the plan areas, is primarily west of Hall Boulevard and southwest of Highway 217. Multi-family units are generally located along major arterials, concentrated on Hall Boulevard, Pacific Highway, and Greenburg. There are eight schools located within the plan area. Among these there is (1) high school, (2) junior high schools and (5) elementary schools. The sch6ol district also owns additional land for future school sites. The City of Tigard presently owns five park sites (62.59) acres) , some of which are not developed. With a present population of 11,058 there is approximately ten acres of park land per 1,000 people in the city (including usable school property) . The City also has 42.17 acres of land dedicated by various developments for public 5. x use. Much of this land lies in the flood plain, and is suitable for paths and non-intensive recreational use. In addition, there are 62.15 acres which are in a semi-public status. In spite of some negative circumstances, resulting from past de- velopment, Tigard has numerous advantages which, if property addressed, allow for a smooth recovery from its unplanned history. First on the list of positive attributes is the topography. The rolling terrain ef- fectively hides the majority of Tigard's development. From I-5 rela- tively little development is visible, only limited industry. For the most part, Highway 217 is below grade, allowing only the very low areas along the highway to be seen. Most of these areas are presently unde- veloped. Pacific Highway is the primary problem from a community design standpoint. Even here, however, only the development directly adjacent the highway is in the usual line of vision from the street. Supplemen- tary to the topography is the abundance of natural vegetation located throughout the community. This vegetation quite often screens develop- ment in lower areas that would otherwise be visible from higher eleva- nn.q_ Besides the screening of present development, there still remains several large undeveloped tracts of land, many of which are along Pa- cific Highway. Properly planned, development of these areas can greatly reduce the visual impact of continued growth. In addition, there are strips of 'land in public rights-of-way that can be landscaped to improve community appearance. A strong planning commitment and community co- operation can be invaluable toward mitigating the mistake of the past while safeguarding the future. 6. Y SECTION ONE: ENVIRONMENTAL PROTECTION AND PRESERVATION Goal : To protect and promote public health and safety, to regulate development in inherently hazardous areas and to preserve environmental quality . Even though Tigard has numerous ordinances and policies controlling development, the policies in this plan were developed as if no controls were presently in existnece. This method was used to ensure a holistic approach to policy formulation, rather than a patchwork or bandage process. People and subsequently governments, face environmental problems as a result of activities that are either improperly located or otherwise contrary to natural processes. Nature offers a well balanced system e of events; natural cycles. When these cycles are disrupted by human intervention, nature may react in an unforgiving manner. In terms of developing the land for human uses, there are certain iihe type and level of activity that physical characteristics thai, m1U t � can safely occur. These characteristics are referred to as natural hazardsor physical h sical limitations. There are three major development limitations which exist in the plan area. They are: 1. Flood plains and Wetlands 2. Runoff and erosion 3. Soil instability. These are discussed in greater detail in the appendix. Even though these limitations to building are characteristically separate, they are linked through the interrelated natural processes that create them. These interconnections are directly related to the roles of: 7. ' 1 , geologic deposits and processes 2, water and the hydrologic cycle s 3, soil properties ` 4, slope 5. vegetation 4 In order to minimize potential development hazards due to physical limitations and hazards, these interrelationships require a program of coordinated control, ensuring the balanced continuation of nature's processes. c t PHYSICAL LIMITATIONS The physical features which form the make-up of any piece of land have a direct relationship to the type and density of development which can be accommodated on that property (carrying capacity) . Combinations such as steep slopes and unstable soils create severe development con- straints (appendix ) . Excessive development in such physically x limited areas greatly increases the potential severity of landslide, E. earthquake damage, flooding, etc. Policy 1. Designate areas of physical limitation (poorly drained, seasonally flooded, ground instability) and incorporate these designations in i the city zoning ordinance and map, and develop graduated development ; restrictions according to the distinct characteristics of the con- straints and anticipated limitations. FLOOD PLAINS,. WETLANDS AND RUNOFF/EROSION " Qe ■ Often in the past, development has occured along streams and drain- ageways that are subject to periodic flooding. This reduces the natural capacity of the land to control runiff and erosion and consequently in- creases the potential for flooding during times of peak rainfall . Objectives: Using the detailed information gathered on flood plains, wetlands and areas of serious drainage problems, develop policies to : 1 . Control development, and encourage non-intensive uses, in these areas. 2. Minimize the runoff-erosion impact of development on the surrounding area and downstream properties. 3. Emphasize the retention of a vegetation buffer along streams and drainageways, to reduce runoff and flood damage and provide erosion control. In the process of evaluating the plan area for flood plains and wet lands, several informational problems were identified: 1 . Discrepancies were found between calculated flood elevations and their demarcation on the official maps. 2. Vague delimitation of flood plains along Summer and Red Rock Creeks. 3. Lack and distinction between the floodway (area of fastest stream flow) and the flood plain fringe. 4. Lack of reliable hydrologic data regarding flood levels expected from future development. In addition to these problems there is the issue of the cumulative effect of development upstream of Tigard. Flood levels in Tigard will be substantially determined by the controls exercised over development - outside the plan area (see appendix ) . ■ Z Policy 2. The city shall initiate a cooperative, interjurisdictional water shed, f storm drainage and flood plain management study of the Funno Creek basin, and establish restrictive interim standards for development until sufficient data is available to set standards at identified i levels of adequacy. Interim standards shaZZ limit the rate of runoff i and erosion caused by a development both during and at completion of construction, as well as development in all flood plain and wetland areas identified in the physical inventory. The Fanno Creek drainage system includes numerous small water courses. The integrity of these natural drainageways is intrinsically connected to the system's capacity to reduce excessive runoff and subsequent flood levels. Often, however, developers alter these water courses to suit their development purposes, usually to provide more usable land. The resultant adverse impacts are detrimental to the entire drainage system Policy 3. The City shalZ restrict alteration of natural drainageways unless it can be demonstrated that the benefits are greater than the detrimental effects. otherjurisdictions in the Fanno Creek Basin shall be en- couraged to do the same. Besides the basic need to control development in flood prone areas, it was found that public knowledge of flood plain hazards was lacking. Many of the obstructions previously placed in the flood plain were the result of either ignorance or overly optimistic attitudes about potential flooding problems. These obstructions (eg. Main Street Bridge) hinder the flour of high water and tend to increase flood levels. 10. Policy 4 . The city shall develop methods of removing and/or flood proofing major obstructions within the flood plain. The city should also consider methods of educating the public regarding the flood plain. Vegetation, without a doubt, (appendix ) serves an essential func- tion in the process of runoff and erosion control . Nonetheless, it is too often removed and replaced by buildings and asphalt. Policy b. The City shall adopt an ordinance to regulate the removal and/or replacement of existing natural vegetation in designated areas (flood plains, drainageways, areas of high visibility, unique habitats, or rare species). Significant trees or stands of timber shall also be protected. Proper administration of the above policies relies heavily upon the availability of adequate information upon which to assess the environmental impacts of a project . The development , which creates the need, should be responsible for providing the city with the necessary data for making sound decisions. The burden,after all, is on the applicant to prove that the project will not adversely affect the environment or create undue future liabilities for the City. Policy 6. Require a site development report (eg., hydrology, soils, geology) for major projects in designated areas; and a statement reflecting methods to be used, to minimize the runoff erosion impact of the development on the sourrounding area and downstream properties. 44' } _--._---------- t SECTION Two• t ENV 11ZO!,!11 'NTA1 C01MIMUNITY DE TGN Gcal: To preserve areas and features of significant natural or scenic beauty. To enhance the opportunities fog continued enjoyment of the natural environment of the community. } Goal: To preserve andi'or conserve renewable and nonrenewable resources. ; To protect and promote the ecology of the community and to dis- courage premature and unnecessary conversion of open space to urban uses. 4 i This section serves as a manual for environmental community design. {. It proceeds beyond the neighborhood planning process by establishing en- vironmental policies and tecIniaues for accommodating the various types f of land use proposed in each Ne ghborhood Plan. '"he guiding premises of this section are that site and Building Designs should allow for proper functioning of each element involved in a Development project. Each development should also be complementary to the community' s natural . attractiveness. A review of the community's development history reveals the all too common occurance of natural amenities being unnecessarily replaced by asphalt and buildings. The result hes often been to increase flood potential while detracting from the pleasant atmosphere a primarily residential community should maintain. A community's design should be directly related to and easily identified with the function the com- munity serves. While Tigcrd is fortunate to have a viable employment base in the form of industrial and commercial businesses, it is funda- mentally a residential community. 12. A residential environment calls for a pleasant, relaxing atmosphere. The community design then, should include those aesthetic and natural features considered complimentary to a desirable living environment. One of the key features is the maintenance of a sense of openness. Open space not only provider visual relief but also recreational op- portunity. Therefore, one of the objectives of this section is to ensure that a full complement of open space, in both large and small reserves, is pro- vided as future development occurs. Once again, nature provides the essential ingredients, as well as a development guide. Fanno Creek and its tributary system provide an excellent opportunity for linear open space, linking the entire community together. Pclicy 7. Retain the 100 year flood plain of Fanno Creek, its tributaries and the Tualatin River as an open prese=rve (Greenway). The Greenway shall be established as the backbone of the open sT)ace network and when a direct public benefit can be derived, ie. , when adjacent residential development, the Greenway should be developed for passive recr.eaticn and pedestrian/bike travel. Policy 8. To au ument the scenic benefit of the Greenway, the City should establish the major vehicular transportation routes as scenic or visual corridors. The Park Board should plan and initiate a program (through public and private cooperation) for cooridor landscape preservation and/or improvement. i 13. r 1 M r } ht. The design of developments within the community can be regarded E from two view points; the design of structures as they relate to site and R b function (architectural design) ; and their relationship to the sourrounding area (community design) . Both aspects are of equal import- ance. 4 Good architectural deisgn is necessary to provide visual variety and allow for individual identity. At the same time, good community design provides a sense of unity with other development while eliminating conflicting appearances. Policy 9. In order to realize a sense of integrated community design, the design review ordinance shaZZ be modified to include specified g s landscape objectives, emphasizing the incorporation of natural vegetation and unique topographic features in site design. Careful consideration should also be given to the 3600, 3 dimensional. impact of a site and structure design. In considering the overall character of the community, it is important to look to the past. As a community develops it should not discard its past for the sake of the future. Historic features provide a link with the past and add character and variety to the community's design. Unfortunately, much of Tigard 's heritage has already been lost ' to deveiopmeh with only a few distinct structures remaining. There `have been some extensive efforts by local citizens to document the history of Tigard for the enjoyment of future generations. These efforts should be supported. 14. f Yx _ Policy 10. To preserve t!'.e Community' s hostory, an index of historic sites shall be developed and made available to the general public; a program shall be developed to acquire and/cr resotre, a number of historic structures (through public and/or private effort) identified. as significant. The City should also consider the development of or preferably the renovation of a his tori c structure as an histroic museum or cultural center, meeting; hall complex, (ie. , Durham. School) . t. Another matter w"ich requires attention as an eler:ent of environ- �. mental community design is the issue of farm land resources. Tigard's heritage is linked to its agrarian n^' b g_. past and maintai. ing some record k and vestiges of this disappearing history should be a community concern. ' In addition, farm land ties into the pattern of open space set forth in the cOmmunity' s design objectives. i Until the early 19501::, Tigard primarily remained an agricultural R` community. However, since the conversion to suburban uses began, in- � creasing amounts- of farm land have been converted to other uses. In evaluating the remaining agricultural Land for potential pre- ' ;� servation it must be recognized that Tigard Lies within the urban grolArth boundaries established by CRAG. Under these cirucrostances, preserv- ing large reserv-ing ,large tracts of farm land would place an unnecessary burden on the community to increase densities elsewhere to comnensate the the loss of f. needed residential space. An additional consideration is that most 4 3 of these remaining parcels are not large enough to be economically a viable. t ,t r 15, essentially, in a fast growing suburban community like Tigard, the is- sue of preserving farm land should be left up to the individual prop- erty owners. (policy 11. Deleted by Council.) '- Another resource issue than can be related to community design is the extraction of sand and gravel deposits which are found in the plan area. For the most part, this resource is scattered in small deposits. Some, however, may be of sufficient size and quality to warrant future extraction. The manner in which these areas are exploited and especially re- habilitated after extraction has both environmental and design implica- tions. However, the environmental concerns can be addressed through proper design criteria. Policy 12. If natural resource extraction is determined to be feasible, the City shall develop extraction and rehabilitation stand- ards to minimize environmental problems and conflicts with x adjacent land uses. ter' 4 k"JA , j a 'ECTICN1XrrrE coal: To provide an adequate diversity and quanti'' of passive and active recreational opportunities fo^ the community's residents. Rapid growth in a community like Tigard tends to diminish the availability of land for recreational purposes. Increasing land values are a compounding factor and tend to inhibit acquisition of quality recreation land. Simultaneously, regional growth containment boundaries have been drawn, increasing the pressure for development inside the boundaries. Tigard is locnted within the growth: containment area. Therefore, increased demands for development can be expected., resulting in even greater pressures to consume available ore,n spece. "3hile the supply of land decreases, the need for recreational space increases. An urgent reed, tht;reforc .. exists to provide these facilities by devising a method for fi.:ancing a land acquisition and development program that can compete with the pressures of development. Since new development will generate the increased demand, such a financ- inc method must look +-award -this new development bearing its share of the financial responsibility. In the process of pl.anninF for a park and recreation system it is necessary to classify the individual components (neighborhood parks, greenway, etc.) which will or could comprise the park system. In addition, the establishment of a reasonable acquisition and development program requires n listing of priorities and minimum levels of service to be provided. The actual development of such a system requires relating the provision of facilities and servico to the particular needs and recreation desires of the residents to be sewed. Policy 13. Park classifications and standards shall be adopted and a program developed for the acquisition and development of a park and open space system capable of ensuring an adequate supply of usable open space and recreational facilities, directly related to the specific needs of the local residents. 17. f l 1 c wide: for the and p _ intended a,� � � s ai'e mp1e fol.lowin standards 0 c. ery L i+ orrUr's nd -t� to devele mesi as - z n ark system Whict, re _. € development Of a p�. s of the Cityt s residents. r sraried recreation.1. need � is respcxisi.v e to the -h- is to nei;h1�or- res differ from neit,...w ;peci.fi needs ^nd desires ac�- owever; r h r rr S1C'r T:"ts cannot b2 hoed. 111 C ddition., t ;t- nee''s of Lu.u_e re c rea�or;.; the par!,: r.evelopmen"t di.�t_ : ct.. cora tel , ra ectec .

In the following component standards t'-':e words Shall, and Should are used to denote= a_ minimum desirable level of facilities that shall be provided, :and an additional level that should be provided, if possible. The sise and population figures act i>s a gl-tide, but each park should reflect, in its size ant', design the relationship between people, space and facilities the site is intended to offer. The sine and acres per 1000 population figures are set at an average desirable level for each component. Tr^ overall desirable level set by these standards is 10 acre per 1000 people lahich is ap- roximately the present level provided within the City. In combination, these standards constitute an ideal park sy-stew. Basic Assumptions: 1. The Idea]. Par'_ System is intended to serve as a guide and will be used to evaluate decisions or. the ongoing process of parks development. It will also serve as the basis for establish-n- a r.ysternns deti�elopnen t program. . 2. Due to economic constraints or population characteristics the Ideal may never be reached.

Pedestrian/Bicycle Pathways One or the most important factors to a successful park system is safe and convenient access tc the various park sites. The City cur- rently has a Pedc-strian/Bikenpth Plan (adopted in 1974) but pat.k. construction has been slow and seriously underfunded. This plan re- emphasizes the need for the paths and recommends the system be pro- vided in the following manner. Policy 18. Safe and convenient pedestrian/bike routes shall be provided th,rough,_)ut the community. All major street construction or improveiae.ciLb s"Iell bu uoordinaLed wilvh Lhe coiarmuriiLy bicycle path plan and facilities provided. Pc icy 20. The City should budget an adequate portion c'L public works or general account monies for path construction each budget- ing year: and seek ad.ditional funds through grants, special levies and other sources. Policy 21. When land is developed and includes a designated pedestrian/ bicycle path route, easements shall be granted -to the City. In cases where development increases the need for the path, construction should also be required. 'vlhen development occurs that is not on a designated bikepath route, but in- creases the need for a path, a contribution to a special 28. .bikepath construction fund should be sought. Policy, 22,-.In areas where a pate is routed through or adjacent to a residential area, the path and/or the buildings ir: the area should be situated in a manner to provide natural surveillance of the path. The number of entry points to the path should also be limited in these areas. In addition, it is recommended that a pathway and bridge be constructed allowing the linkage of Conk Park to Tualatin Park in the City of Tualatin. This would conform to the parks plan prepared by the City of Tualatin. It would also increase the potential for state and/or federal funding of such a project. RFCOInIENDF.D IMi'I:F.'MENTATIOPV MEASURES The most important element of this plan is a reasonable and effecitve met',od of implementation. It is not uncommon for well in- tended park and open speice plans to be relegated to collecting dust on a shelf due to a lack of sound proposals for land acquisition and development. In addition, plans proposing strong implementation devices can fail in public hearings or as a result of court challenges because they may be judged inequitable and/or arbitrary in their manner of coliectinb fees and dilctrib„tinv benefits. The major problems identified in other system°; which have failed in court or through administration are: . 1. No reasonable/direct connection between where money is spent and where it is collected; no benefit to those who pay. 2. Arbitrary site select i.or, after :Honey is collected. z 3. Lack of equitable participation in payments, especially deal- ing with multi-family units versus single-family, and arbitrary* level of fee accessed. 4. Legal challenges due to excessive front-end costs to developers. 29. x } s >. .i�ac',i of c'dmini.,trati'7e methods to insure parx Sit?S are c e.z r r pre,� eta and charge: are collected.

As a bonus for this method of planning, a usable network of open spaces for recreation and relaxation is identified and permanently set aside. Growth in any community means a reduction of open space. Across the nation , houses are covering agricultural land, flood plains and wetlands are being filled and � . built on, and a multi- fi tude cf unique natural features are being exploited and lost forever. At the same time, growing popula- tions place an in- � .F creasing premium on the preservation of these same resources . x The loss of forest lands, Scenic view, M �xi wildlife habitats, ' and increasing pollu- tion arl(ic emphasis to the need for pre- p� ~ � "` `13 servation of our " valuable resources These conflicts between growth and the environment are the result of the several components of urban development competing for the use of our land resources to suit their specific needs and desires. The basic conflict is between the individual land- use rights and the broader interest of the entire community. This is a major philosophical question for which there is rising pres- sure to resolve. Tigard and other local governments throughout the land are confronted with this issue on a daily basis . The solution undoubtedly lies in the recognition of the necessity for maintaining an equitable balance between the, government's desire to protect. the public interest and individuals' , businesses' , and corporations' wishes to use their land as they please. This Plan recognizes the value of the natural environment and attempts to establish the degree of respect due the land. This 1 Y is accomplished through a process of using nature as the major guide to land development . In the following plan, nature' processes are used to determine policy direction to insure that continued development will be in harmony with the natural features of the community and in the best interest of all concerned. The Plan policies are presented in three major sections. The first section, ENVIRONMENTAL PROTECTION AND PRESERVATION, deals with natural processes (storm water runoff, erosion, etc. ) . It also sets the framework for sections two and three: Using environ- - -r; ,_ , cr i. -o iUa., sGct 4 Vn Vile establishes cons-iructi.on and location mental controls for all types of development. Specific areas such as flood plains, steep slopes and natural habitats are categorized as nondevelopable and set aside as permanent open space. Section two, ENVIRONMENTAL COMMUNITY DESIGN , augments these controls by offering community design criteria for the purpose of integrating development with the physical features of the area. These criteria are centered primarily on the appearance of a struc- ture and its relationship to topography; natural vegetation and surrounding land uses. The third section, PARKS AND RECREATION , completes the pack- age by formulating policies and standards to guide the development of a system of parks and open spaces aimed at maximizing recrea- tional opportunity and aesthetic benefit to community residents. The open space system proposed by this Plan was generated by using the lands designated (from section one) as environmentally unsound for construction as its foundation. The majority of these unbuild- able lands are along Fanno Creek and -its tributaries and are re- ferred to in the Comprehensive Plan as the Greenway System. In addition, the Greenway is augmented by specific sites selected for their environmental uniqueness (e.g. , attractiveness, historic value and/or recreational potential) . The in rli vidual co°'�^^�^ � c .t,. ncn s of the open space system are to be linked together for optimum accessibility, use, and enjoyment, by means of a network of pedes- trian/bike paths. Thus, the total package yield3 an integrated community design. The design ensures the continuance of natural cycles and enhances the visual attractiveness of the community. Simultaneously, the community benefits in several ways: Psychologically, through retention of essential natural fea- tures which daily remind the individual of the delicate thread connecting each person 's life to the natural order of things; Sociologically, from expanded recreational opportunity allow- ing diverse community participation in outdoor activities, and through a community design that promotes community identity; Personally, from increased health and safety derived from reduced air pollution (e.g. , natural air purification of trees) and minimized potential for damage to property or loss of human 2 l life, caused by natural hazards such as flooding and land slides; 1 And Economically, through efficiencies in supplying public services (police , fire, water) to a unified area, and from an enhanced city image promoting increased property values and attract- ing new employment in the form of commerce and industry.

It is situated in the southeast portion of Washington County abutting portions of west- ern Clackamas and Multnomah Counties. However, in order to accom- modate expected growth and to give consideration to areas directly influenced by the City, the plan area boundaries were drawn out- side the actual city limits (see map page 4) . The plan area is served by three major auto transportation routes, Pacific Highway, Highway 217, and Interstate 5. Two rail lines also serve the area. PHYSICAL SETTING Tigard is located at the lower end of the Fanno Creek Drain- age Basin which empties into the Tualatin River at the City 's southern boundary. This location makes flooding a particular community concern which this plan addresses. However, while Fanno Creek poses the threat of periodic flood- ing, it also offers the natural asset of a relatively undeveloped and heavily vegetated meandering course through the center of the community. This feature' becomes even more attrac- tive when the tributary _ `T'a streams are added, as they flow between gently rolling; hills often covered with significant stands of timber. The major topographic relief in the plan area isin the western portion in a the form of Bull and Little Bull Mountains. . Elevations within thea` plan area range from 500 feet near the top of Bull Mountain to 110 feet at the Tualatin River. (See physical inventory maps, ) DEVELOPMENT PATTERN Since the early 195O 's, the community has undergone, at an increasingly rapid rate, a transformation from rural to suburban land use. Development was uncontrolled and unplanned until the adoption of the 1971 Tigard Community Plan. The Community Plan 5 was the City's first attempt to counteract the unsightly strip commercial and disjointed residential sprawl of the 1960 'x. Fortunately , since the Community Plan , more atten- tion has been given to aesthetic design. Never the- less, Tigard is left with an undesirable scar of F strip commercial develop- ment along Pacific Highway. Early development also exploited the natural amen- ities of the community , ., inefficiently consuming land with little regard for natural processes or recreational space . COMUERCIAL/INDUSTRIAL DEVELOPMENT The land use map (see Physical Inventory text) shows the ma- jority of the commercial activity being centered on Pacific High- way with increasing development along Highway 217 and Hall Boule- vard. The more intensive industrial uses occur west of Interstate 5, along 72nd Avenue and follow the Burlington Northern and Southern Pacific railroad tracks. RESIDENTIAL DEVELOPMENT While scattered throughout the plan area, residential devel- opment is primarily west of Hall Boulevard and southwest of High- way 217. Multi-family units are generally located along major arterials, concentrated on Hall Boulevard, Pacific Highway , and Vt.cc.uhui. g Road. SCHOOLS AND PARKS There are eight schools located within the plan area.. Among } these there is one high school, two junior high schools and five elementary schools. The school district also owns additional land for future school sites. The City of Tigard presently owns five park sites (62.59 acres) , some of which are not developed. With a present population of 11,058 there is approximately ten acres of park land per 1,000 people in the City (including usable school property) . The City also has 42. 1.7 acres of land dedicated by various developments for public or semi-public use. Much of this land lies in the flood plain , and is suitable for paths and non- intensive recreational use. i 6 4 Ill sprit c� elf sInct ire ci r'c uulsttnl� e's, rc ;,ul t int; lrc�m 1>ast ClE'1'C'I()f)l,lt'1i1. , �l'i r'(1 Il;lr; rlt it 1'ulr�; adV'ail r `l'' fhlllj> f rtntlotll }l r sl (lT'V` addrrSaw d, zl l lov' it lrsi (ul tilc� list l� l attrihut pu r�lf>Ilv .

Even though Tigard has numerous ordinances and policies con- trolling development, the policies in this plan were developed as if no controls were presently in existence. This method was used to ensure a holistic approach to policy formulation , rather than a patchwork or bandage process. People, and subsequently governments, face environmental prob- lems as a result of activities that are either improperly located or otherwise contrary to natural processes. Nature offers a well balanced system of events--natural cycles. When these cycles are disrupted by human intervention, nature may react in an unforgiv- ing manner. In terms of developing the land for human uses, there are certain physical characteristics that limit the type and level of activity that can safely occur. These characteristics are referred to as natural hazards or physical limitations. There are three major development limitations which exist in the plan area. They are: 1. Flood Plains and Wetlands, 2. Runoff and Erosion, and 3. Soil Instability. These di°a discussed in greater d(-tail in the Technical Report Section. Even though these limitations to building are characteris- tically separate, they are linked through the, interrelated natural processes that create them. These interconnections are directly related to the roles of: 1. Geologic Deposits and Processes, 2. Water and the Hydrologic Cycle, 3. Soil Properties, 4. Slope, and 5. Vegetation. In order to minimize potential development hazards due to physical limitations and hazards, these interrelationships require a program of coordinated control , ensuring the balanced continua- tion of nature's processes. 8 PHYSICAL LIMITATIONS The physical features which form the make-up of any piece of land have a direct relationship to the type and density of devel- opment which can be accommodated on that property (carrying capac- ity) . Combinations such as steep slopes and unstable soils create severe development constraints (see Technical Report) . Excessive development in such physically limited areas greatly increases the potential severity of landslide, earthquake damage , flooding, etc. POLICY 1. Designate areas of physical limitation (poorly drained, seasonally flooded, ground instability) and incorporate -these designations in the city zoning ordinance and map, and develop graduated development restrictions according to the distinct characteristics of the con- straints and anticipated limitations. FLOOD PLAINS, WETLANDS, RUNOFF AND EROSION Often in the past , development has occured K t o`' along streams and drain- r ageways that are subject .j , to periodic flooding. This reduces the natural capacity of the land to control runoff and ero- sion, and consequently increases the potential for flooding during times of peak rainfall . a . 0 tives Using b 'ec J the detailed information gathered on flood plains, wetlands and areas of serious drainage prob- lems, develop policies to: 1 . Controll development , and encourage nonintensive uses, in these areas. 2. Minimize the runoff-erosion impact of development on the surrounding area and downstream properties. 3. Emphasize the retention of a vegetation buffer along streams and drainageways, to reduce runoff and flood damage and provide erosion control . In the process of evaluating the' plan area for flood plains and wet .lands, several informational problems were identified: U 5 S5 tr l 1. Discrepancies were found between calculated flood ele- vations and their demarcation on the official maps. 2. Vague delimitations of flood plains along Summer and Red Rock Creeks. 3. Lack of distinction between the floodway (area of fastest stream flow) and the flood plain fringe. 4 . Lack of reliable hydrologic data regarding flood levels r expected from future development . t In addition to these problems, there is the issue of the cumulative effect of development upstream of Tigard. Flood levels in Tigard will be substantially determined by the controls exer- cised over development outside the plan area (see Technical Report) . t POLICY 2. The City shall initiate a cooperative, interjurisdic- tional mater shed, storm drainage and flood plain management, study of the Fanno Creek basin, and estab- lish restrictive interim standards for development until sufficient data is available to set, standards at identified levels of adequacy. _Interim standards shaZZ limit, the rate of runoff and erosion caused by a development both during and at, completion of con- struction, as well as development in all flood plain and wetZond areas identified in the physical inventory. The Fanno Creek drainage system includes numerous small water courses. The integrity of these natural drainageways is intrin- sically connected to the system's capacity to reduce excessive runoff and subsequent flood levels. Often, however, developers -alterthese water courses to suit their development purposes, usually to provide more usable land. The resultant adverse im- pacts are detrimental to the entire drainage system. POLICY 3. The City shall restrict alteration of natural drainage- ways unless it can be demonstrated that the benefits are greater than the detrimental effects. Other jur- isdictions in the Fanno Creek Basin shall be encouraged to do the same. Besides the basic need to control development in flood prone areas, it -was found that public knowledge of floodplain hazards was lacking. Many of the obstructions previously placed in the i , 10 I® r flood plain were the result of either ig- norance or overly Ci optimistic attitudes about potential flood- ing problems. These i obstructions (e .g. ~� Main Street Bridge) hinder the flow of high water and tend to increase flood levels . f POLICY 4. The City shall deveZop methods of removing and/or flood proofing major obstructions within the flood plain. The City should also consider methods of � educating the public regarding the .flood plain. Vegetation , without a doubt (see Technical Report) , serves an essential function in the process of runoff and erosion control . Nonetheless, it is too often removed and replaced by buildings and asphalt . POLICY 5. The city shall adopt, an ordinance to reg julate the removal and/or replacement, of existing no ur-rZ vege- tation in designated a?leas, q. fZnod pla2ns, drain- ageways, areas of high visibility, unique habitats, or rare species. Significant, trees or stands of timber shaZZ also be protected. Proper administration of the above policies relies heavily upon the availability of adequate information upon which to assess the environmental impacts of a project . The development , which creates the need, should be responsible for providing the City with the necessary data for making sound decisions. The burden , after all , is on the applicant to prove that the project will not adversely affect the environment or create undue future liabili- ties :for the City. POLICY 6. Require a site development report., e .g. hydrology, soils, geology, for major projects in designr.cTt.ed areas; and a statement reflecting methods to be used to mini rrrize the runoff erosion impact of the deveZopmPnt on t,Yte surrounding area and downstream properties. 11 E , `se f MM uj Al.

To enhance the opportunities for continued enjoyment of the natural environment of the community. GOAL: To preserve and/or conserve renewable and nonrenewable resources. To protect and promote the ecology of the community and to discourage premature and unnecessary conversion of open space to urba.n uses. This section serves as a manual for environmental community design. It proceeds beyond the neighborhood planning process by establishing environmental iolicies and techniques for accom- modating the various types of land use proposed in each Neigh- borhood Plan . The guiding premises of this section are that site and building designs should allow for proper functioning of each element involved in a development project . Also, each develop- ment should be complementary to the community 's natural attrac- tiveness . A review of the community 's development: history reveals the all too common occurance of natural amenities being unnecessarily replaced by asphalt and buildings. The result has often been to increase flood potential while detracting from the pleasant atmos- phere a primarily residential community should maintain . A com- munity 's design should be directly related to and easily identi- fied with the function the community serves. While Tigard is fortunate to have' a viable employemnt base in the form of indus- trial and commercial businesses, it is fundamentally a residential coRli iuiii Ly. A residential environment calls for a pleasant , relaxing atmosphere. The community design then, should include those aesthetic and natural features considered complimentary to a de- sirable living environment . One of the key features is the main- tenance of a sense of openness . Open space not only provides visual relief but also recreational opportunity. t- Therefore, one of the objectives of this section is to ensure that' a full complement of open space, in both large arid small reserves, is provided as future development occurs. Once again , nature provides the essential ingredients, as wellasa develop- ment guide. Fanno Creek and its tributary system provides an excellent opportunity for linear open space, linking the entire community together. (See Open Space Map. ) 12 x i. 1 +1 �9 POLICY 7. Retain the 700-year fZood plain of Fanno Creek, -its tributaries and the TuaZat,in River as an open preserve (Greenway) . The Greenway shall be established as the backbone of the open space network and when a direct, public benefit can be derived, i. e . , adjacent residers- tiaZ deveZopment., the Greenway should be developed for passive recreation and pede.st,rian/bike travel . I � r J ° POLICY 8. To augment the scenic benefit, of the Greenway, the City should establish the major vehicular t.ransportoti.on routes as scenic or visual, corridors. The Park Board Should plan and initiate a program (through public and private cooperation) for corridor landscape preservation andfor _improveme.nt,. 13 The design of developments within the community can be regarded from two view points; the design of structures as they relate to site and function (architectural design) , and their relationship to the surrounding area (communtiy design) . Both aspects are of equal importance. Good architectural design is necessary to provide visual variety and allow for individual identity. At the same time, good conununity design provides a sense of unity with other de- velopment while eliminating conflicting appearances . DnT T nXr n L V. in Order to reaZ2ze a sense Of integrated community design, the design review ordinance shaZZ be modified to incZude specified Zandscape objectives, emphasizing the incorporation of naturaZ vegetation and unique topographic features in. site ryesign. CarefuZ considera_ tion. shouZd also be given to the 3000, 3-dirnensional impact of a site and structure design. (1 In considering the overall character of the community, it Yg' is important to look to the past. As a community develops it should not discard its past for the sake of the future. historic features AA provide a link with the past and add character and variety to the community's design. Unfortunately, much of Tigard's heritage has already been lost to development with only a few 'distinct struc- tures remaining, (See Technical ^ ° n F ReP01 • ) There have been some extensive efforts by local citi " tens to document-thehistory of Tigard for the enjoyment of future generations., Continuation of such efforts _should be supported. f All } 14 POLICY 10. To preserve the community 's history, an index of historic sites shall be developed and made avaiZ- ab Ze to the general public; a program, shall be developed to acquire and/or restore a number of historic structures (through pubZic andlor private effort) identified as significant. The City should also consider the development of, or preferably the renovation of, an historic structure as an historic museum or cultural center, meeting ha1Z complex, i,e. LUrham School. Another matter which require:. attention as an element of environ- mental community design is the issue of farm land resources. Tigard's heritage is linked to its agrarian past and maintaining some record and vestiges of this disappearing history should be a community concern. In addition, farm land ties into the pattern of open space set forth in the community 's design objectives. Ungil the early 1950 's, Tigard primarily remained an agricultural community. However, since the con- version to suburban uses began, in- creasing amounts of farm land have been converted to other uses. In evaluating the remaining agricultural land for potential pre- servation, it must be recognized that Tigard lies tyithi_n the urban growth boundaries established by CRAG. Under these circumstances, preserving large tracts of farm land would place an unnecessary burden on the community to increase densities elsewhere to compensate for the loss of needed residential space. An additional consideration is that most of these remaining parcels are not large enough to be economically viable.

Y i. _ r + s i i I. r PARKS AND RECREATION r f GOAL: To provide an adequate diversity and quantity of passive � and active recreational opportunities for the community 's residents. Rapid growth in a community like Tigard tends to diminish the availability of land for recreational purposes. Increasing land values are a compounding factor and tend to inhibit acqui- sition of quality recreational land. Simultaneously , regional growth containment boundaries have been drawn , increasing the f pressure for development inside the boundaries. Tigard is loca- ted within the growth containment area. Therefore , increased demands for development can be expected, resulting in even greater � pressures to consume available open space . i While the supply of land decreases, the need for recreational space increases. An urgent need, therefore , exists to provide these facilities by devising a method for financing a land acqui- sition and development program that can compete with the pressures of development . Sincenewdevelopment will generate the increased demand, such a financing method must look toward this new develop- ment :bearing its share of the financial responsibility . I t In the process of planning for a park and recreation system, it is necessary to classify the individual components (neighbor- hood parks, greenway, etc. ) which will or could comprise the park system. In addition , the establishment of a reasonable acquisi- tion and development program requires a listing of priorities t 1 n prC e actual .' i and 1311 il.l.nlUlfl levels of Sr'rvi%c o. „,.. provided. �'h � d C op-_ 4 ment' of such a system requires relating the provision of facili- ties and services to the particular needs and recreation desires of the residents to be served. POLICY 12. Park classifications and standards shaZl be adopted and aprogram developed for acquisition and develop- ment of a park and open space system to ensure an adequate supply of usable open space and recreational } facilities, directly related to the spa.ci fic-needs of the Local residents. The following standards and policies are intended as guides for the development of-a: park system which reacts to development as it occurs and to the varied recreational needs of the City 's residents.' However, specific needs and desires differ from neighborhood to neighborhood. In addition, the needs of future 17 s I t residents cannot be accurately projected. For these reasons , the park development districts (see Open Space Map) were established. The districts were selected based on present development patterns, the selected park standards, and by using major streets as access barriers . They are not permanent and may be adjusted in the future if circumstances change. The purpose of the dis- tricts is to provide service areas where the amount and types of recreational facilities can be planned for and eventually provided based upon the specific needs of the people residing there.

Activity Centers PARK STANDARDS In the following component standards the words Shall, and Should are used to denote a minimum desirable level of facilities that shall. be provided, and an additional level that should be provided, if possible. The size and population figures act as - a guide, but each park should reflect, in its size and design, the relationship between people, space and .facilities the site is intended to offer. The size and acres per 1000 population figures are set at an average desirable level for each component . The overall de- sirable level set by these standards is 10 acres per 1000 people which is approximately the present level provided within the 18 City. In combination, these standards constitute an ideal. park system. Basic Assumptions: 1. The Ideal hark System is intended to serve as a guide and will be used to evaluate decisions on the ongoing process of parks development, It will also serve as the basis for es- tablishing a systems development program. 2. Due to economic constraints or population characteristics the Ideal may never be reached. However, policy decisions should be based on priorities that are economically feasible, but also directed toward the established Ideal System. 3. The assumptions, data, criteria and policies should be periodically reviewed to account for changes in circumstance. The park acreage standards are set for lands available to the general public, and owned or otherwise controlled by the City or a cooperating public agency. They do not include: 1. Public school property (not available for active recre- ation) . 2. Special areas (pathways, cemetaries, golf courses, etc. ) . 3. Private or voluntary agency lands and facilities. 4. Vacant undeveloped land not under ownership or control of the City. i y 19 m E.' r t (. r � �i J S ,t PARK AND OPEN SPACE STANDARDS 1.

Individual park sites, as defined by the parks and open space standards and classification system should be de- veloped according to the following priorities: A. Facilities within a park will be adjusted to meet the needs and desires of the district residents and the characteristics of the site. Park and/or recreational facilities in great- est demand and least supply should receive the highest development priorities. B. Parks should be planned to insure maximum benefit to the greatest number of local residents. For this reason, acquisition and development of community level parks should be given the highest priority. C. Development of additional neighborhood parks will have a lower priority for public funding and are encouraged to be provided by the private rector within planned unit develop- ments. D. Mini parks have the lowest development priority and should be supplied at public expense only if an area is determined to be isolated from access to other parks, or where space is extremely limited. E. Provision of regional park facilities will only be considered as an interjurisdictiona project; and should have a low priority unless unusual circumstances arise. F. Cook Park should be considered a Zarge.urban park and should be fulZy developed before consideration is given to another facility of this classification. The expansion of this park will be a high priority. G. Acceptance of any land dedicated for park purposes shall be based upon its usefulness and adaptability to the adopted park and open space system. POLICY 15. New developments shall be responsible for funding their share of new parks, based on an established acreage standard. The City shall, however, seek additional funds through public sources such as special levies and grants. 26 POLICY 16. Developers shall be given a choice of optional ways to provide open space based on the established park acreage standard. They can either; Z. Contribute to the systems development fund in proportion to the established park acreage standard. 2. Develop a portion of an existing park equivalent to the park acreage standard for their project. 3. Develop a new park on site subject to the approval of the City. Density bonuses should also be considered for open space provided, which exceeds the park acreage requirements; but shall be granted according to the standards established by the separate neighborhood plans. COMMUNITY SCHOOLS Tigard School District 23J owns large tracts of land with- in the plan area, some of which are slated for future develop- ment to meet increased demands. Schools are public facilities, and their buildings consume considerably less than the total acreage avaii.able. They also provide many recreational facilit- ies such as gymnasiums, tennis courts, etc. For these reasons, they are an obvious source of additonal open space and rec- recational opportunity. POLICY 17. The City shall work toward establishement of a cooperative arrangement with the school districts (community schools program) to ensure provision of adequate year -round rec- reational programs and facilities, and to eliminate un- necessary overlap of facilities. Beyond having an adequate supply of land available, there is a necessity for continual parks planning and development as the demands for space increase. In conjunction with providing facilities there is mounting pressure for the provision of year round recreational activities. Unfortunately, the present city staff does not have time to devote to park development and recreational program planning. Therefore, it is important that adequate staffing be provided to assist the Park Board in the task of coordinating the planning and development of the City's Park and Recreation program. This is a continuing and complex assignment which should not be entrusted to a volunteer appointed body without qualified staff assistance. 27 PEDESTRIAN/BICYCLE PATHWAYS One of the most important factors to a successful park system is safe and convenient access to the various park sites, The City currently has a Pedestrian/Bikepath Plan (adopted in 1974) but path construction has been slow and seriously under- funded. This plan reemphasizes the need for the paths and recommends the system be provided in the following manner. POLICY 18. Safe and convenient pedestrian/bike routes shall be pro- vided throughout the community. All major street con- struction or improvements shall be coordinated with the community pedestrian/bicycle path plan and facilities provided. POLICY 20. The City should budget an adequate portion of public works or general account monies for path construction each budgeting year and seek additional funds through grants, special levies and other sources. POLICY 21 . When land is developed and includes a designated pesestrian/ bicycZe path route, easements shall be granted to the City. In cases where development increases the need for the path, ` construction should also be required. When development occurs that is not on a designated Bikepath route, but in- creases the need for a path, a contribution to a special bikepath construction fund should be sought. POLICY 22. In areas where a path is routed through or ai�jacent to a residential area, the path and/or the buildings in the area should be situated in a manner to provide natural surveillance of the path. The number of entry points to the path should also be limited in these areas, e 28 e 8 k In addition, It is recommended that a pathway and bridge be constructed allowing the linkage of Cook Park to Tualatin Park in the City of Tualatin. This would conform to the parks plan prepared by the City of Tualatin. It would also increase the potential for state and/or federal funding of such a project. 29 �t LA �l I `- t RECOMMENDED IMPLEMENTATION MEASURES The most important element of this plan is a reasonable and effective method of implementation. It is not uncommon for well intended park and open space plans to be relegated to collecting dust on a shelf due to a lack of sound proposals for land acqui- sition and development. In addition , plans proposing strong im- plementation devices can fail in public hearings or as a result of court challenges because they may be judged inequitable and/or arbitrary in their manner of collecting fees and distributing benefits. The major problems identified in other systems which have failed in court or through administration are: 1 . No reasonable/direct connection between where money is spent and where it is collected; no benefit to those who pay- 2. Arbitrary site selection after money is collected. 3. Lack of equitable participation in payments, especially dealing with multi-family units versus single family and arbitrary level of fee accessed. 4. Legal challenges due to excessive front-end costs to developers. 5. Lack of administrative methods to insure park sites are preserved and charges are collected. 6 . An additional problem Tigard has to face is the City/ County jurisdictional split . GREENWAY/PATH SYSTEM In addition to park land, this plan continues to support the greenway concept as a means of providing open space and protect- ing the natural drainage system. It establishes the greenway as the hub of the open space system. The greenway was originally proposed in the 1971 Community Plan which established Fanno Creek and its major tributaries as a source of linear open space. It also proposed that the greenway system serve as a route for pe- destrian/ bicycle travel . In 1974 the City adopted the Pedestrian Bicycle Patn Plan . The plan specified which portions of the green- way should function as actual pathways. The 1974 plan calls for paths along: 1 . The entire lenght of Fanno Creek within the plan area, 30 2. Summer Creek from Tiedeman to S.W. 135th , 3. The watercourse that flows from Bull Mountain through Jack Park to Summer Creek , and 4. The watercourse that flows through the Genesis, Path- finder area to S .W. Walnut Street . Retaining the natural drainage system in its natural state will save the public many times the cost of a piped drainage sys- tem. At the same time, the areas listed above, as pathways , pro- vide excellent opportunity for passive recreation and pedestrian/ bike travel . Because this system will benefit all local residen- tial properties, financing of its acquisition and development should come from all residential properties in the Plan Area . Each new residential development should, therefore , share in maintaining the existing natural drainage, system and also the re- sponsibility to provide public access to and through the areas in- dicated as pathways. However, not every developable parcel con- tains flood plain property , and, for this reason, seeking green- way dedication from only those properties adjacent to a water course would not be reasonable. This plan , therefore, sets out a system whereby all land development would share in the financial responsibility of protecting the natural drainage system. GREENWAY ACQUISITION AND DEVELOPMENT It is proposed that the following financing method be estab- lished for the development of the greenway system. At the time of final plat approval of residential developments, a fair share fee will be assessed ($/acre) for development of the drainage and pathway system. The fair share formula would be as follows: A =. P/D A = Fair Share Assessment P = Total Cost of Proposed Green- way Path System (see Techni- cal Report) D = Total Acres of Buildable Res- idential Land (see Technical Report) Developments with portions of their property in the flood plain or a designated drainage/pathway may dedicate land and pro- vide a portion of the pathway in lieu of the assessment. If more than the fair share is dedicated, the developer will be reimbursed for the excess. If less is dedicated, then a partial fee will be assessed. 31. �4 This formula will ensure equal participation in greenway ac- quisition and development. It does not , however, provide suffi- cient funds for maintenance of the pathway system. i These funds can be provided by assessing a fee on all resi- dents, The assessment to be designated as a public utility fee for maintaining the storm drainage/pathway system. The fee could be attached to the water bill to insure full participation in fi- nancing. This will , of course, be dependent upon satisfactory ar- rangements with the local water districts. PARK LAND ACQUISITION PROGRAM The acquisition and development of parks and recreational k facilities will be funded by a System Development Charge which will be assessed on each new residential unit . The charge will be assessed at the time of issuance of the building permit. Dedica- tion of land may be accepted in lieu of the fee provided that it meets the standards set in the plan for park sites and is approved by the Park Board. The formula and procedures will be as follows: 1. Establish two park service districts using Pacific High- wayas the boundary and assign an account to each dis- trict. Money received will be spent in the district it is collected from. 2. Identify a specific (most desirable) park site. Each site sized according to the standards set in the Plan. The location of each site will be determined by develop- ? ment patterns and the desires of the residents within the specific park district. I 3. Establish an assessment based on the acres/population standard set in the plan (1 acre/100) and the average sale value of residential land in the Plan Area (updated annually) . The charge per unit will be based on the ave- rage ve rage people per unit ratio (census tract data, updated annually) . Dedications of the land will be considered in lieu of the fee. 4. Administrative procedures will be established to ensure collection of the system development charge at the time of issuance of each building permit for a dwelling unit and that no unsatisfactory land is accepted, through dedi- cation , in lieu of the fee. 5. Arrangements should be made with the County for the col- lection of the system development charge in the unincor- porated portions of the Plan area. 32 t C SYSTEM DEVELOPMENT CHARGE FORMULA A x P x $ = S A = Park Acreage Standard *P = Average # of People per Unit **$ = Average Sale Price of Residen- tial Land S = System Charge t e t m,. a } * Certified by PSU Center for population research. ** 'Estimated by Washington County 's Office of Assessment and Tax- ation. 33
