The Master Plans have been developed through the collaborative efforts of the Park Board, City staff and interested citizens. Facilities and site improvements identified in the Master Plans are needed to help meet the present and future recreational needs for the citizens of Tigard. When the plans are implemented, both Tigard and the larger metropolitan area will benefit. Besides helping to meet the recreational needs of the community, and preserving important natural areas, the implementation of the Master Plans will work to support commercial and residential development in the City. The development of Fanno Park will directly complement anticipated improvements to the City Center. The outdoor recreational opportunities offered in the park will attract area residents to the Main Street area and increase their exposure to this commercial center. Further, the park improvements will provide an attractive setting for the commercial area, making it a more pleasant experience for shoppers and the commercial clients. The improvements at all these parks will significantly expand the variety and quantity of recreational facilities available for the citizens of Tigard. This expansion of recreational opportunity will enhance the livability of the community and its attractiveness for the area's residents. cvu � wL'j e .nom 'y ,' +i .r" 4)37.`.fes' J �._ ` ;,. ....,,, ��59 , l+r ��,y,gyp'.' •".=_ �'�Tf r 1F o 1 • COOK PARK MASTER PLAN �i • ` ' p . .tee . Co s Cook Park Master Plan An overall view of the Master Plan recommendations shows the recognition of three separate and unique areas in Cook Park. The first is the upper area where the existing Little League and soccer fields, large picnic area, playground, picnic shelter, and restrooms are located. This is the area where the greatest variety and quantity of recreational facilities are to be found. Presently, and as provided for in the Master Plan, this is to be the area where the highest concentration of active recreation will occur. The second are the areas of natural riparian and wetland vegetation. This includes most of the river bank, the large wooded area in the central and eastern portion of the park and the small wetland area north of the soccer fields,. These areas are to remain in a natural state. Only limited trail work, interpretation displays and habitat enhancement will take place. �/�) Cil' Al _ C m.+a-•» tyr f'1:7 1 Y v `t� .t Ij < ,, ,;, , ditle The third is the riverfront around the area of the existing boat dock and launching ramp. Presently this area is used for limited picnicking and launching of small craft into the Tualatin River. While this is one of the few access points to this river, the launching area is little used. Beyond these recreational uses, this area is used for storage of surplus materials. The Master Plan calls for improvements to this area which will significantly expand picnicking and river-oriented recreation. Several overall objectives served to direct the development of the Master Plan for Cook Park. The first objective was to take care of the need to update and improve existing facilities. Existing irrigation systems, the playground, Little League fields, and restrooms all have become worn with use and time. Rehabilitation improvement and expansion, in the case of the playground, is needed to meet present recreational demands. The second objective was to provide additional recreational opportunities by adding new facilities. A fishing area designed to accommodate the mobility handicapped, parking, and expanded picnicking are indicated for the riverfront area. These and the other related improvements in this area will allow for expanded and more intensive use of the riverfront. Riverside trails and roadside bike lanes are included 2 I to make the park more accessible and useable by bicyclists. Additional soft trails, trail heads and interpretative displays are included to provide for improved use of the natural woodland area. The wetland north of the soccer fields is improved to both provide a better edge to the park and to improve the habitat value and potential educational uses of this site. In the upper area of the park, the expanded playground and spray pool will greatly enhance the use of the park for families. The bandstand and adjacent expanse of lawn will improve the park's function for musical and other community events. The inclusion of the caretaker/gatehouse and small utility garage will improve park security, enable the collection of entry fees (if this becomes desirable), and improve efficiency of maintenance operations in the park. Irrigation of all new and existing developed areas are included to both improve park use and reduce maintenance and operational costs. The third objective was to improve the safety and utility of the park. Improvements to the safety of the park are to be accomplished in a number of ways. First, rehabilitation and updating of existing facilities will eliminate potential hazards. Second, widening of the access road to include bicycle lanes and the provision of separate riverside trails will provide for safer use and access of the park. Finally, realignment of the main access road to the outer edge of the most active recreation areas will limit pedestrian crossing and other conflicts between park users and cars. Improving the utility of the park has been accomplished by adding facilities (as mentioned in the previous page), relocating access roadways and by regrading and stabilizing the bank in the riverfront area. Relocating the access road occurs in two locations. The main access road is presently located between the main picnic and playground area at the Little League fields. This road is relocated to the north and to the west of the Little League field, eliminating the division of the park. This realignment allows for the redesign of this active recreation area and provides a more supportive and complementary juxtaposing of recreational facilities. This frees up this central area of the park, allowing for the expansion of the playground and the addition of a spray pool, bandstand, and large lawn area to this area of the park. This provides a central focus, unity, and organization which the park presently lacks, improving the safety, utility and aesthetics of the park. ,, • ` �• h` . • .rv..a _ , • . 3 Relocation of the riverfront roadway and parking to the north, away from the river's edge, expands the useable space along the river and allows for the addition of new, and improvements of existing facilities in that area. The Master Plan calls for significant upgrading of the riverfront area. An improved approach, and parking, will allow for better use of the river access ramp. Paving of the road at the parking area will improve access. Regrading of a stretch of the riverfront to provide for a gradual sloping "beach" will improve use by canoeists and riverbank fishermen. Additionally, "handicapped" parking, paved walkways and a paved river edge plaza will provide access and a fishing platform for mobility- impaired citizens. seta *?tt%11.4.‘,.....0414M‘ 4 . akvimmla 7‘S 441.41"." The final objective has been to improve the aesthetics and other visual attributes of Cook Park, making it a more attractive and supportive resource for the community.

This site is a segment of a proposed greenway corridor which runs the length of the Creek, within the City of Tigard, extending downstream to the confluence with the Tualatin River. The park's function as a part of this linear corridor, the natural environments which make up most of the proposed park, its location in a floodway, and it's contiguousness to both the Main Street commercial area, the Civic Center, Senior Center and residential areas are all important factors which directed the development of the Master Plan. The objectives the Master Plan hopes to achieve include: 1. Public land acquisition needed to complete the securing of this segment of the greenway and park. 2. Completion of this segment of the greenway's trail system. 3. Development of recreation areas to support activities in the Main Street commercial area and at the Civic Center. 4. Preservation of the natural habitat corridor. 5. Improvement of the public's recognition and use of this community recreation resource system, through the development of recreational facilities, nature interpretative displays, and other means. 6. Identification of features and facilities in the park which are compatible with, and tolerant of periodic flooding. Presently, only the eastern portion of the proposed park is under public ownership. The portion of the floodplain west of the Civic Center still needs to be placed in public hands. In addition, a key parcel which is out of the floodplain, at the western edge facing onto Main Street, needs to be obtained to provide adequate visual and physical access and presence for the park in that important commercial corridor. An 8-foot wide paved path is called for to run the entire length of the park. This path and smaller segments connecting it to the northern and southern edges of the park will provide access to and through Fanno Creek Park. Creating adequate linkage through the park is especially important because of its role in the larger greenway trail system. To assure an adequate route for through travel, a pathway on the southern edge of this park is shown for the segment west of the proposed 6 Ash Street extension. This will be needed when the area on the north side of the Creek is fully developed and becomes too congested to be a suitable trail route. Providing more cultural or active recreational areas to support the Main Street commercial area and Civic Center, and preserving the natural vegetation; leads to the delineation of three distinct areas within the park. The first area is referred to as the "Main Street Plaza and Water Garden." This area lies to the north of the creekbed and extends from Main Street, east to the Ash Street extension. This area is designed to be intensively used and programmed for a variety of recreational, civic, and commercial functions. The ability to provide for numerous activities and functions will make this a strong attraction for the community, serve to support the adjacent commercial area, and meet the community's need for recreation. This site is seen as an important part of developing the Main Street and City Center area into an important focus for the citizens of Tigard and surrounding areas. The elements shown in this area are designed to be integrated into the future commercial establishments to be developed along this segment of the River. Facing on Main Street is a paved urban plaza. Portals mark the edge of the square and the entry to the park. Steps along the southern edge of the square lead directly down to the creek, reinforcing the physical and visual connection of the waterway to the park adjacent to the commercial area. In the creek, adjacent to the plaza, water steps (small waterfalls) are indicated. These help improve water quality and provide visual and auditory interest for the park.

This pond functions as a visual focus for this part of the park, reinforcing the water-oriented theme of the park. In addition, this larger body of water serves to enhance the habitat diversity of the park, buffer the natural areas from more intensively-used portions of the park and thereby support a more stable environment for birds and other wildlife in the park. A large water jet is indicated in the center of the pond. This, or a similar feature, functions as a visual focus, while improving the water quality of the pond and masking sounds from the nearby Pacific Highway. On the northern shore, trees and green lawns lead down to the edge of the pond where varieties of water-loving herbaceous perennials and shrubs are planted. The theme of this area, as insinuated by the name, is that of an English water garden- -tended, but not manicured. This informality is in place both to reinforce this theme, and to provide a design capable of weathering periodic inundation by high wintertime water levels. In the middle of the north shore, an amphitheater is shown. This will provide a location for outdoor plays, concerts, other performances, and public events. On the eastern shore of the pond, a "Tea Garden" is indicated. This includes a tea house and garden area where tea, and other refreshments can be served. This location could be managed by a concessionaire for the general public and for holding of special group meetings or receptions. The plaza, amphitheater and "Tea Garden" are all facilities that can be programmed and operated to generate revenue to support the maintenance and operations of the park. / r...._....w `__, 9 Illi raga :.6 a',' � ,f ,a [,-._3,-, . „iii 8 The "Civic Center Water Garden" is the second distinct area. This area is at the eastern end of the park, immediately south and east of the Civic Center. This is a small area of maintained lawn, trees and water edge perennials and shrub plantings. A pond is excavated in the location of an existing overflow channel to create a visual focus for the area and to diversify the area's natural habitats. A small weir is shown at the downstream edge of the pond to control summertime water levels. An aeration spray head and pump may need to be installed in the pond to improve water quality. In addition to the pond excavation, a small channel is shown connecting the stream to the backwater slough adjacent to the Civic Center. This is indicated to help improve passage for wildlife and to improve the water quality in the backwater area. On the edge of a second pond, a small arbor and patio are shown. This arbor and surrounding lawn area will be used for picnic lunches and small gatherings to complement the plaza areas at the Civic Center. 1 z `c�` _' r kms4c. _' ,'i ". r• _ - V it! ...,,,,- :.:},,. ,2.4:. iie..-7;;,,,,,,,_;:,-.. 401.-_.._,,s:.,7e.„...:,\ . 4.,..,.:,,,,...1., .. .., 4,4 sp., .N. .,......„4,.„. , 4 4.

The rest of the park, comprising the majority of the park area, is indicated to be a nature preserve. Here natural vegetation and habitat areas will remain undisturbed or altered to improve their natural character and ability to support the area's wildlife inhabitants. This includes preservation of a large portion of the center of the park in an undisturbed state. On the western end, adjacent to the "Main Street Water Garden," the blackberries that crowd the Creek edge will be removed and native trees, shrubs, grasses and herbaceous plants are called for. This includes a planting of native materials along the southern edge of the Creek adjacent to the plaza area. This is needed to assure a continuous corridor of _ natural vegetation along the Creek. This is important for the maintenance of diverse and stable populations of native plants and other wildlife. 9 • At the eastern end of the park, at Hall Boulevard, an entry plaza with interpretative and educational displays are indicated. This is indicated, not only to inform visitors about the natural environs of the park, but also to call the public's attention to the fact that Fanno Creek is a public park and nature preserve. ,,- - 54„4-----\___- -1 Q. l,. i�1 /yr It. .atiPI',fin:'. , .M� , !

The park is located on Summer Creek. The proposed greenway corridor along this creek will be an important extension of the park's recreational features. Summer Lake was formed by the damming of the creek. The low flows of Summer Creek have led to some water quality problems in the lake, but efforts are underway to attempt to mitigate these problems. Presently, development of and access to the park are limited. The completion of Winter Lake Drive will greatly improve access to the park. The program of land acquisition and development, identified in the Master Plan, will provide the space and facilities needed for community park activities. The objectives for the Master Plan include: 1. Acquisition of additional lands to provide adequate buffering from residential areas and space for needed recreational facilities. 2. Provision of recreation facilities and features needed to meet community and neighborhood needs. 3. Preservation and enhancement of existing and potentially significant natural areas. Land acquisition called for by the Master Plan include the upper half of the western end of the park, the area around the conference/reception facilities, and the southeast portion of the park, south and east of the lakeside path. Acquisition of these parcels will complete the enclosure of the lake, provide an amount of land needed to provide adequate facilities, and land needed for a park-like setting for the lake and surrounding park. Recreation facilities indicated in the Master Plan are aimed at providing recreation for the community as a whole, and surrounding residential areas. First of all, Summerlake Park is a recreation "node" on the proposed Fanno Creek greenway. When the greenway and associated trail system are completed, many of Tigard's citizens will have safe and convenient access to the park along this route. The trail system called for on the Master Plan will both complete the segment of the greenway path which runs through the park, and provide facilities for popular forms of recreation (e.g. jogging, walking, and bicycling) in the park. The paved trail system includes roadside sidewalks, an 8-foot wide paved trail all around the lake, and bridge over the dams and at several small stream crossings. In addition to the paved trails, a 6-foot wide "soft" trail is indicated looping the lake. The trail runs alongside the paved trail around the lake and conference/reception area, forming a loop over 8/10 of a mile in length. Cutting through the middle of the loop, 11 another segment of the soft trail system runs between the existing forest and southwest edge of the lake. The conference/reception facilities indicated south of the forested area will provide the community and neighborhood with flexible and attractive places for meetings and special events. Revenues generated by this facility, if desired, can be used to offset park operating expenses. a.,..,d s t; .�,..• t1 (,. k I tie 0 ,A. a' .-<s-- . 'ik, •,`..1. Nil NA f 440 r �, 4.

These include tennis and basketball courts, playground and spray pool, large open grassy play area, a restroom, parking lot, a picnic shelter and a picnic area capable of handling a small group or a number of individual picnickers. At the southeast corner of the park, an additional playground, restroom, large grassy play area, and lakeside docks are indicated. t M s .

The specific layout, position, and variety of facilities indicated in the Master Plan have been tailored to provide for community-wide needs in a way compatible with, and supportive of the surrounding neighborhood area. Achieving a complimentary relationship with the neighborhood is also accomplished by providing a shrub buffer for the existing homes along the northern edge of the park and the future residential area southeast of the lake. Planting of tree groupings along the lakeshore is intended to provide screening of the residential areas, while maintaining views onto the lake. Landscaping and mounding between the street and parking areas will provide visual buffering of these areas for the residential areas south and west of the park. The large mixed evergreen and deciduous forest in the center of the park, the islands in the lake and the lake edge itself, all provide a rich environment for natural vegetation and wildlife. The Master Plan calls for the preservation of the forest and adjacent lake edge wetland in their natural status. A soft surface trail through this area will provide a pleasant exercise route, and an opportunity for those hoping to observe wildlife up close. Enhancement of the lake edge and lake island involves reestablishment of more natural and diverse vegetation. This involves both the planting of native plant materials and the limiting of lake edge mowing to allow native plants to establish themselves. The lake and woodlands are an important link along the Fanno Creek greenway corridor. The preservation and enhancement efforts called for by this plan will not only maintain the continuity of this corridor, but also provide an attractive setting for the park itself.

A7 APPENDIX B REVIEW & PERMIT REQUIREMENTS COOK PARK The Cook Park Master Plan developed by Murase associates calls for some modifications to the north bank of the Tualatin River and to a wetland area adjacent to the existing soccer fields. The purpose of this discussion is to give a preliminary indication of the type of improvements proposed and the procedure necessary to accomplish the work. The modifications to the bank of the Tualatin River will involve flattening the gradient of the slope along a portion of the bank to allow for public access to the river. Currently the riverbank is steep and does not lend itself to easy access by either pedestrian or boat traffic. This improvement will provide for fishing, canoe and handicap access to the edge of the river. The slope will require I, treatment to guard against erosion due to changing river levels pedestrian traffic I ' and storm runoff. Slope protection can be accomplished by using concrete ( • pavers similar to Grasscrete that allow for soil and grass to be placed in the voids at the surface of the slope. The concrete will provide stability while the vegetation will give an aesthetically pleasing appearance. The improvements will require a portion of the bank area northwest of the boat launch to be excavated and a gradual slope extended to the edge of the water. ;1 The material removed will be used in an area adjacent to the access road and turnaround. The excavation and fill in this area will need to balance so that no change in total flood storage volume is lost. In addition, the question of how this excavation will affect flood flows both up and downstream of this site will need to be addressed for the U.S. Army Corps of Engineers to evaluate the impacts of these proposed improvements. The approval process for this work along the Tualatin River will include a joint submittal to the Oregon Division of State Lands and the U.S. Army Corps of Engineers. These applications will place the proposed project into two separate approval processes. The U.S. Army Corps of Engineers' permit will involve the evaluation of the impact to the Tualatin River floodway and flood plain zones. j This project is not anticipated to significantly impact the floodway or flood plain.However, the grading will receive a close look by the Division of State Lands. This permit will heavily involve the Oregon Division of Fish and Wildlife which will evaluate the impacts on the riparian vegetation and the wildlife habitat B1 i!' - Items required for this submittal are earthwork calculations, mapping of proposed improvements, determination of "mean high water" and "ordinary high water" levels, elevations or cross-section views, existing shorelines, etc. The Division of State Lands and U.S. Army Corps of Engineers may require additional items beyond those listed on the application, depending on public involvement and environmental impacts to sensitive areas. The wetland area under consideration for enhancement is just to the north of the soccer fields. It is proposed that the wetland be excavated to provide a deeper pond and the area planted with more diverse wetland type vegetation. This improvement will enable the present wetland to serve a broader spectrum of wildlife. Another benefit of this improvement will be the cleansing effect that the pond will provide for surface water runoff from uphill development. A very important item associated with the improvement of this wetland area will be control of the drainage into and out of the pond and its relationship to the overall drainage system for the park. These improvements will require a joint permit application similar to the one discussed as part of the riverbank improvements. The application to the Oregon Division of State Lands and the U.S. Army Corps of Engineers will require a description of the proposed improvements, earthwork calculations and a preliminary planting plan utilizing plant species from the approved Oregon Division of Fish and Wildlife plant materials list. B2 FANNO CREEK PARK The proposed improvements to the Fanno Creek Park include the creation of two backwater areas. One of these is located between Main Street and the proposed extension of Ash Street. The other is located just west of Hall Boulevard and behind City Hall. These areas are to be controlled by weirs in the stream channel. The larger of the two is located between Main Street and Ash Street and will require the diversion of water from the main stream channel into a new pond adjacent to the creek. This pond will require aeration by use of a water spray jet and introduction of fresh water from the Fanno Creek stream flow. This process could possibly be supplemented during dry weather conditions by pumping water into the pond from a proposed new well adjacent to the site. Flow of water from Fanno Creek into the pond would be controlled by a weir in the main stream channel, allowing normal stream flows to continue after the pond level is reached. Careful consideration will need to be given to flood levels and flow, both upstream and downstream, of this site so that this improvement will not affect those flows and potentially damage adjacent properties. Flood flow calculations completed for final design will consider the existing channel configuration and compare its flow characteristics to those of the proposed channel. These flow characteristics will be used to determine the flood depth at selected points along the stream corridor during flood flows. The weirs will be designed so that they will not create restrictions to the stream flows during flood stage on Fanno Creek. The additional flood storage volume created by the new backwater area will provide a significant mitigation to the weir installation in the main channel. The second backwater area will be formed using a weir in the main stream channel approximately 280 feet upstream from S.W. Hall Boulevard. This pond area will be located in the stream channel and will be much smaller in size than the one upstream from the Ash Street crossing. Design requirements for this weir and pond area will be the same as those discussed relative to the larger pond. The main difference will be that this backwater area will be within the channel and will be used to increase the wetland adjacent to the stream and to provide a more diverse wildlife habitat. B3 ,1 ;F �'1 • In all cases, the design calculations will need to show that the proposed improvements will not alter the flood plain or the 100-year flood contours. This will be done by designing the grading such that, for all fill within the flood plain, there is a corresponding removal. No fill will be allowed in the floodway, and jany structure placed within the park will need to be assessed as to its impact on the flood flows through the stream corridor. The permit process for this site will be the same as that for the riverbank improvements within Cook Park. A joint permit application will need to be made to the Oregon Division of State Lands and the U.S. Army Corps of Engineers where equal weight will be given to the evaluation of the impact on the flood plain, floodway and the wetland habitat. Different from the Cook Park improvements along the Tualatin River, these proposed improvements will heavily involve the evaluation of both the flood plain and floodway issues, as well as the environmental concerns of those affected property owners and the Oregon Division of Fish and Wildlife. I Another state permit process that will be required for the construction of these ponds will be through the Oregon Water Resources Department. There are two permits required for this type of improvement. First, a determination of water rights will need to be made by a Certified Water Rights Examiner and an affidavit filed with the state showing the water rights for these parcels of property. Then, two permits will be required. One of these will give the right to create the pond area and to appropriate water to fill the ponds the first time. The second permit will allow the continual appropriation of water to maintain the ponds. These two permits deal with the water rights for this property and will require additional mapping to show where the property is relative to a section corner or Donation Land Claim Line. This mapping will need to show the point or points of water diversion from the main stream flow relative to the reference corner or line. These permit applications will need to be prepared in cooperation with a Water Rights Examiner and will need to be accompanied by a certificate indicating that the property has the right to appropriate water from Fanno Creek. f E. 1°. B4 GENERAL COMMENTS Timing for the processing of these permits range from 45 days to 8 months, depending on the complexity of the application. The permits for Cook Park should only take 45 days to process, unless a private party or one of the reviewing agencies express a serious concern. Possible concerns will be relative to wildlife habitat and damage to the existing wetland areas. In both cases, a planting plan showing existing and final plantings would be very helpful to the Oregon Division of Fish and Wildlife in their evaluation of the permit. If this information is supplied to their office, it could help speed the processing of these permits. Improvements to Fanno Creek Park are more significant than those proposed in Cook Park relative to the existing stream and the surrounding vegetation. These improvements will require significant documentation for review by both the U.S. Army Corps of Engineers and Division of State Lands. Within the Division of State Lands' review process, the Oregon Division of Fish and Wildlife will have the heaviest involvement. Although the proposed improvements are extensive, this permit should only require a maximum of 45 to 60 days to process. This proposal will make improvements to the Fanno Creek flood plain and floodway requiring careful documentation and design to verify that the changes in the channel will not change the flood flow velocity or depth, either upstream or downstream from the park. Because of the complexity of these proposed improvements, we would anticipate that the U.S. Army Corps of Engineers' permit will be more time consuming. Depending on the level of detail required from the U.S. Army Corps of Engineers' office, this permit could take up to 4 to 6 months to process. The Water Resources Department permits could be the most time consuming of all because of the backlog of work due to recent changes in Oregon State Law. This new law requires all subdivisions of land to have their water rights established prior to recording. The Water Resources Department does not have a very large staff and therefore this last year has had trouble processing all the applications in a timely manner. This may change as their department is able to shift some of the workload to outside consultants. This application could take 6 months or longer, depending on the Water Resources Department's workload at the time the submittal is made. It should be noted that all permit applications could be processed simultaneously. This may help the agencies to coordinate their review and thereby speed the permit process. B5 APPENDIX C Cook Park Riverfront Improvements Additional work was done to refine the design of the improvements to the riverfront boat launch area at Cook Park. This area is one of the few access points to the Tualatin River and improving this area is seen as a way to expand recreational use of this river. Presently, the steep riverbank, limited developed area, and poor parking inhibit this area's usefulness. A number of refinements were identified by these efforts. First a fishing plaza and paved walkway were added to provide access to the river edge for the area's mobility-impaired citizens. The dock was relocated closer to the boat launch area to make it easier for for people to launch their boats from this ramp. The eastern end of the road was curved further to the north to provide more grassy sloped areas adjacent to the river. Finally, the boat launching and parking areas were revised to eliminate unneeded road crossing by the riverfront trail. i • ' i Cl • a At 1 ,,,,A I 1 ., u,1I TI� I II I r -_ k3 „ . ----\_,5_,5(.7-_) , 111\\\\ , ' 1 % I I , I /' �-. ��\� ) Ire\\ i / \ \\1\ \ M ,x 111 V I I I yE A�;,, � �f \ Illi IiiIII I 1 I 1 �" `..
