December 1994 1 INTRODUCTION The City of Tigard contracted Fishman Environmental Services (FES) to update their existing wetlands inventory (SRI, 1989) to meet the Division of State Lands' Local Wetland Inventory (LWI) requirements and to conduct a wetland functions and values assessment. The boundaries of the 11.4 square mile Active Planning Area, the study area for this project, are shown in Figure 1. The FES amended scope of work included the following tasks: Task 1: Identify Aquatic Resource Areas, (refered to in this report as "Resource Units), based on ecological, geomorphic and planning parameters and verify approach with Division of State Lands (DSL) and Department of Land Conservation and Development (DLCD). Task 2: Update existing inventory of wetland areas based on current DSL inventory standards. Verify that the previously identified wetlands sitll exist and that the approximated boundaries are correct. Collect location and quantity information for any newly identified wetland sites. Task 3: Conduct a wetland function and value assessment of identified wetlands according to the Oregon Freshwater Wetland Assessment Methodology. Task 4: Recommend significance criteria and provide a preliminary identification of significant sites. Task 5: Prepare a report incorporating the results of Tasks 1 - 4 that will satisfy DSL and DLCD requirements. It should be noted that Task 2 involved a significant amount of work to bring the Tigard Wetland Inventory up to current standards for state approval as a Local Wetland Inventory under ORA 141-86-180 through 141-86-240. This report presents the information generated under the scope of work. The approach prepared by FES for this project was based on stream corridor assessment rather than assessment of individual sites. The majority of wetlands inventoried in Tigard are closely associated with Fanno Creek and its tributaries, particularly Ash Creek and Summer Creek. Fanno Creek has long been recognized as a significant resource by local, state and ID° Fishman Environmental Services page 1 Figure 1 CITY OF TIGARD Of STUDY AREA FOR LOCAL WETLANDS INVENTORY UPDATE Pi..4=-"'-' ACTIVE PLANNING AREA OUTSIDE CITY LIMITS P le ,s CITY OF TIGARD BOUNDARY Vt■1, ------ 1— IL ' 0 1 Ail 4 ,971.' --' - •- RAI'y ais , L RD iar 19411411r1 All An iiii "MIN a IIIII MB mi.71, ,_ r ri II:41 ".l' \......1 0 t 22. 1 a smommmen ' immumimm '--' ....,- a 1 1 ' 4'''' -- - .51 NE • , .• A 1- N PF Ilk :-T V cP L 0 - / °4e- ) i wrfti -\ ii41 - ..) 0 , . s mho G j ..-- ... 1 S :16411. 11111140 .,.., , ,,....„)./ \ pc2' I ,'.•'it.

An analysis of natural resources focused strictly on wetlands minimizes the importance of the Tigard streams; the wetlands, streams and riparian units together constitute a dynamic, interrelated ecological system. We therefore developed an approach for completing the Goal 5 inventory and conducting the ESEE analyses that identified stream corridor segments as resource units. One stream corridor segment might include several associated wetlands previously identified as separate sites. In addition to making more sense ecologically, this approach resulted in fewer total resource sites, thus saving time and dollars when conducting conflicting use and ESEE analyses. This approach is allowed by Goal 5 by using a "watershed" approach and explicitly considering the following Goal 5 subsets: open space, scenic, fish and wildlife habitat, • wetlands and water areas. We met with staff from DLCD and DSL to confirm the acceptability of this approach. The distribution of wetlands within the study area is closely associated with existing surface drainage patterns (Figure 2). Fanno Creek is the dominant stream system. It follows a north to south flowing course from its headwaters in the West Hills of Portland to its mouth at the Tualatin River. It is fed by two major tributaries, Ash and Summer Creeks, and 8 minor tributaries, Red Rock, Pinebrook, Ball, Derry Dell, Krueger, Hiteon, and two with unknown names. Wetlands along Fanno Creek and its major tributaries are relatively long and narrow and are limited to the floodplain by topographic features. Two small perennial streams, Copper Creek and an unnamed stream, flow south directly to the Tualatin River along the southern border of the study area. A few isolated wetlands, including agricultural ponds, golf course ponds, and a stormwater detention pond, also were identified. 2 METHODS 2.1 Task 1. Delineate Aquatic Resource Units The 1989 Wetland Inventory for Tigard identified 117 individual wetlands. The City's wetland and zoning maps were used to delineate 11 Aquatic Resource Units defined by stream reaches and zoning patterns; these units are shown in Figure 3. Field surveys confirmed that these units were valid. Fishman Environmental Services page 3 Figure 2 .

Update Existing Inventory of Wetland Areas (Complete LWI) Field investigations were conducted by Christie Galen and C. Mirth Walker during August through October, 1994. Time spent at each wetland site varied depending on access, the size of the site, and the difficulty of the terrain. Summary sheets were completed for each site (Appendix A). Wetland boundary determinations were previously conducted by another consulting firm using the "Routine Off-site" approach defined in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands (FICWD, 1989). FES followed the 1987 federal method guidelines for determining wetland boundaries (WES, 1987) which is currently used by the DSL for identifying jurisdictional wetlands. Each site was field checked, except when access was denied, in order to update the off-site wetland inventory to LWI standards. Wetland site boundaries were established in the 1989 study based on the following factors: significant changes in habitat (e.g., from a forested wetland to an agricultural field), breaks in natural features created by roads, railways, or development, land ownership, and land use. During compilation of data, the previous consultant lumped sites together that were part of larger continuous wetland systems (SRI, 1989). Additional information that was collected and compiled during the FES study to update the existing inventory included: 1) summary sheets for each site, 2) description of wetland/upland boundaries, 3) mapped hydric soils, 4) acreage, 5) National Wetlands Inventory (NWI) classification (Cowardin et al., 1979), 6) Tax Map Number, and 7) zoning. Summary sheets are included in Appendix A. Background information is included in Appendix B. Wetland boundary corrections were mapped as needed on mylar overlays over black and white aerial photographs (WAC, 3/27/94, scale 1 in. = 400 ft.) by FES staff and then digitized by the City of Tigard. The wetland boundaries depicted on the aerials and mylar overlay are approximate. A formal wetland delineation will generally be needed prior to any site development in order to satisfy the legal requirements of DSL and the U.S. Army Corps of Engineers. Although efforts were made to ensure that no wetland areas within the City of Tigard were missed, there is no guarantee of this. Each wetland was classified according to Cowardin, et al. (1979): palustrine forest (PFO), palustrine shrub-scrub (PSS), palustrine emergent (PEM), open water (OW), and stream (R). The palustrine system includes all nontidal wetlands dominated by trees, shrubs, and persistent emergent vegetation. PFOs in Tigard are typically dominated by Oregon ash, red Fishman Environmental Services page 6 City of Tigard Wetlands December 1994 alder, and Pacific willow with an understory of slough sedge or shrub-scrub vegetation. PSSs in Tigard are rare though shrub-scrub habitat is often contained within forested wetlands. Dominant shrub species include willow, red-osier dogwood, spirea, and ninebark. PEMs in Tigard are dominated by reed canarygrass and also include a variety of grasses and forbs. POWs consist of ponds and other open water areas. Streams were assigned an "R" if they did not contain fringe wetlands or if fringe wetlands were limited; they were designated as "PFO" or "PEM" if they were forested or emergent stream corridors. 2.3 Task 3: Conduct Wetland Function and Value Assessment Wetland attributes were assessed using the Oregon Freshwater Wetland Assessment Methodology hereafter called the Oregon Method (Roth, E.M., et al, 1993), developed by the DSL with assistance from other agencies. The purpose of the Oregon Method is to provide qualitative descriptions of wetland functions and conditions. The Oregon Method is a planning tool. It is intended for use in assessing a number of wetlands within an area to provide a basis for making informed decisions on their protection, conservation, and best ti use. Background information including zoning, floodplain, and fish and wildlife data, was A assembled and a Wetland Characterization data sheet was completed for each unit (Appendix "` E). This is a standardized multiple choice form which focuses on the watershed, the landscape, wildlife habitat, fisheries, hydrology, water quality, access, recreation and r aesthetics and includes compilation of field and office data. Subsequently, Function and Condition assessment questions were answered and Summary Sheets compiled (Appendix E). A description of each Unit and standardized summary sheets are included in the results section. The Oregon Method assesses six wetland functions: wildlife habitat, fish habitat, water quality, hydrologic control, education, and recreation. It also assesses the conditions of sensitivity to impacts, enhancement potential, and aesthetics. A brief description of the • attributes assessed is provided below: Wildlife Habitat - evaluates the habitat diversity for species typically associated with wetlands and wetland edges. No single species is emphasized. Diverse vegetation and ko- structure rate high compared to monocultures with low structural diversity. Fish Habitat - evaluates how the wetland contributes to fish habitat in streams, ponds or lakes associated with the wetland for either warm-water or cold-water fisheries. No single species is emphasized. Shaded streams with instream structure, such as woody ` debris, boulders, and undercut banks, rate high compared to unshaded reaches without instream structure. Fishman Environmental Services page 7 rfo- City of Tigard Wetlands December 1994 Water Quality - evaluates the potential of the wetland to reduce the impacts that excess nutrients in runoff water will have on downstream waters. Urban wetlands adjacent to streams provide greater water quality benefits than isolated wetlands. Hydrologic Control - evaluates the effectiveness of the wetland in storing floodwaters and reducing downstream flood peaks. Wetlands associated with streams provide flood attenuation. Isolated wetlands provide less hydrologic control. Sensitivity to Impact - evaluates the susceptibility of a wetland to secondary effects of impacts. Forested wetlands can be more sensitive to disturbance due to slow regeneration whereas emergent wetlands may recover more quickly. Impacted water quality or quantity may also put wetlands at a greater risk. Enhancement Potential - evaluates the suitability of a degraded wetland site for enhancement. The Oregon Method assumes high value wildlife habitat areas have low enhancement potential because they already provide wildlife habitat values and should not be disturbed. Since urban streams in Tigard provide valuable wildlife habitat, they would have low enhancement potential according to the Oregon Method. FES feels that fish and wildlife habitat would benefit from enhancement activities and consequently has omitted wildlife habitat value from determining the enhancement potential of a site. Education - evaluates the suitability of the wetland as a site for an "outdoor classroom." Criteria in the Oregon Method rely on "safe public access" and diverse wildlife habitat. FES also included proximity to schools as an important criterion to be considered. Recreation - evaluates the suitability of the wetland and associated watercourses for non-powered boating, fishing and similar recreational activities. Recreation rates high if the site provides public access, trails, a boat launch and wildlife habitat is diverse. Aesthetic Quality - evaluates the visual and aesthetic quality of the wetland. Natural settings with diverse vegetation and tranquility rate high compared to areas with low vegetation diversity, constant traffic noise, and unnatural smells. Fishman Environmental Services page 8 City of Tigard Wetlands December 1994 Wetland functions and values for individual wetlands were rated using similar criteria to the Oregon Method but adapted for individual sites to assist in comparing site values and establishing protection measures for significant sites. Functions and values assessed for each wetland included: wildlife habitat, fish habitat, linkage to other open spaces, uniqueness, water quality, hydrologic control, recreation, education, and aesthetics. Uniqueness rated high if the site contained a unique plant community or an unusually diverse mosaic of plant communities. Linkage rated high if sites were connected to larger open space upland areas as well as to drainage corridors. Aesthetic value was rated as described above with the addition of important view sheds adjacent to Highway 217 that were rated Medium. Wetlands adjacent to Highway 217 provide aesthetic views for drivers and also provide a buffer between the highway and other land uses. Individual site ratings are included in Appendix C. 3 RESULTS AND DISCUSSION 3.1 Local Wetlands Inventory A total of 117 wetlands were initially identified in the 1989 study (SRI, 1989). Four of these have been developed (A6, B9, B18, B21) and four of these have been partially developed (A4, E30, G1, G2). During compilation of data, the previous consultant lumped individual wetland sites together that were part of larger continuous wetland systems and separated by roads, railways, or development. To avoid confusion, FES used these same groupings and site numbers. FES also identified five additional wetlands (E39, F24, F25, F26, F27) which were mapped and described. A total of 78 wetland sites were inventoried and summary sheets are included in Appendix A. Wetland acreage totals approximately 295 acres within the City of Tigard's Active Planning Area. The following products satisfy the DSL requirements for a completed LWI: • updated map of identified wetlands; • Wetland Summary Sheets, Appendix A of this report; • LWI Background Information tables, Appendix B of this report; Fishman Environmental Services page 9 City of Tigard Wetlands December 1994 3.2 Wetlands Assessment (Oregon Method) Individual wetlands in the LWI were combined into the following 11 resource units: Unit 1 Upper Ash Creek Unit 2 Lower Ash Creek Unit 3 Upper Fanno Creek from Scholl's Ferry Rd. to Tiedeman Ave. Unit 4 Summer Creek Unit 5 Derry Dell Creek Unit 6 Red Rock Creek Unit 7 Middle Fanno Creek from Tiedeman Ave. to Bonita Rd. Unit 8 Lower Fanno Creek from Bonita Rd. to the Tualatin River Unit 9 Tualatin River Unit 10 Short tributaries to the Tualatin River Unit 11 Pinebrook Creek and associated ponds The following pages contain a narrative description followed by the Oregon Method Summary Sheet for each unit. Table 1 summarizes wetland assessment ratings for the 11 units. Resource unit locations are shown in Figure 3. The specific criteria and rating descriptions for each evaluated function are listed in Appendix D. The rating system is explained below: A: The resource unit provides the function. B: The resource unit has the potential to provide the function (or provides the function for some species - wildlife habitat function). C: The resource unit does not provide the function. The assessment information presented in this report is intended for planning purposes, including the identification of significant natural resources for the Oregon Goal 5 process. Fishman Environmental Services page 10 City of Tigard Wetlands December 1994 The following excerpts from the Oregon Method (Roth et al., 1993) discuss the intended use of this information: The Oregon Method was designed to be defensible if used for its intended purposes. Its end products are qualitative descriptions of wetland functions and conditions. The Oregon Method is based on the idea that the functions and conditions of a wetland system and individual sites must be understood at the local, state and federal levels in order to make management decisions. Completion of this method provides the basic information. When more detailed information is needed, another method should be used. The Oregon Method was designed as a tool for the following purposes: • To educate planners, city council members, county commissioners, planning commissions and members of the community about wetlands in their community • To collect basic information about wetlands in an assessment area, which could be a community, a watershed or a region of the state • To create a database containing information about functions and conditions and other wetland data • To support the planning and decision-making process within a jurisdiction It is necessary to remember that the Oregon Method is a planning tool. It is intended for assessing a number of wetlands in an assessment area, not for evaluating site-specific impacts. The Oregon Method requires each wetland in the study area to be evaluated for the same functions and conditions. It does not determine the wetland's overall value. Using the results of the Oregon Method, communities can make informaed decisions on the protection, conservation and best use of wetlands. Limitations of the Oregon Method are listed on page 4 of Roth et al. (1993). Fishman Environmental Services page 11 IIP Table 1.

PLOT DATE. 02/10/95 City of Tigard Wetlands December 1994 Unit 1 Upper Ash Creek Unit 1, Upper Ash Creek, is located in the northeast corner of the study area, south of Taylor's Ferry Rd. and northeast of the intersection of Hall Blvd. and Oak St. Dominant land use surrounding Unit 1 is residential. Upper Ash Creek contains approximately 8 acres of wetlands including approximately 7 acres of forest and 1 acre of emergent wetlands. The width of the wetland corridor and adjacent uplands varies along this reach from approximately 10 feet to 400 feet. Ample open space occurs adjacent to Cl (agricultural land), C16 (forest), and C13 (Metzger Park, forest). Wetlands in Unit 1 provide four important functions: wildlife habitat, aesthetic quality, water quality, and hydrologic control. Ash Creek and its adjacent diverse riparian and coniferous upland forests provide food, cover, and dispersal opportunities for wildlife attracting migratory and resident species. The riparian corridor is an amenity to the neighborhood and is particularly aesthetic when combined with adjacent upland forest habitat. Fringe wetlands located adjacent to Ash Creek, including forest, emergent, and open water, serve to retain sediments and nutrients during high water events benefitting downstream water quality; water quality is generally excellent at the upstream end of the unit and deteriorates as the stream flows through residential areas and receives stormwater runoff. The wetlands also provide hydrologic control by storing floodwaters and reducing peak flows. • Fishman Environmental Services page 14 Oregon Method Summary Sheet Unit 1 Upper Ash Creek (North & South Forks) Function Evaluation Description Rationale Wildlife habitat A Stream corridor with permanent water&well developed riparian Fish habitat B This reach provides habitat for shiners, dace, sucker, reticulate sculpin, & possibly cutthroat trout. Limited instream structure & dominance of surrounding residential commercial land use reduces fish habitat. Water quality A Stream corridor with FO (43%) and EM (12%); fringe wetlands trap sediment&nutrients. Hydrologic control A Stream corridor provides runoff &flood storage opportunities; fluctuates with beaver dams, rainfall . . . Sensitivity to impact B Urban stream corridor is potentially sensitive to impacts. Enhancement potential A Soil minimally disturbed and most wetlands connected by stream. Education C There are no schools within walking distance. Metzger Park only public land. Recreation B Metzger Park (C13) provides recreation for the public. Aesthetic quality A Most of Unit 1 is a stream corridor with limited noise and garbage. Characteristic Description • Physical characteristics of gently sloping topography with 10 to 100 ft wide wetland corridor; small portion watershed or basin channelized. Ash creek is culverted for numerous road crossings and is dammed at C4,5. It includes 6.8 acres FO, 1 acre EM, and 0.2 acre OW. Biological information Provides fish and wildlife habitat along stream. Narrow buffers except upper end (C1,2) and Metzger Park (C13, C6). Water quality Ash creek has been rated moderate WQ condition by DEQ (1988). Upstream in headwaters(C1, C16) WQ appears excellent, no apparent algal blooms; downstream at lower end of unit, water is degraded. Land use Existing land use within 500 ft of wetland edge includes 27% forested, 60% residential& 13%commercial. Fishman Environmental Services page 15 City of Tigard Wetlands December 1994 Unit 2 Lower Ash Creek Unit 2, Lower Ash Creek, is located between SW Hall Blvd. and the Southern Pacific railroad line west of SW Greenburg Rd. Unit 2 begins at the southern end of Unit 1 and ends at the confluence of Ash Creek with Fanno Creek. Lower Ash Creek contains approximately 25 acres of wetlands including 5 acres of forest, 14 acres of emergent, and 6 acres of open water. Most of the wetlands occur in the Ash Creek flood plain with the exception of C9-11 and B13 which are physically isolated due to residential development. Lower Ash Creek is one of the most disturbed wetland resource areas in Tigard. It is bisected by Hwy 217 and is also crossed by SW Greenburg Rd. Ash Creek traverses an area of mixed residential, commercial, and agricultural land uses. Agricultural land is rapidly becoming comercially developed; three sites (B9, B18, B21) have been filled since the 1989 wetland inventory. Wetlands in Lower Ash Creek provide two primary functions: water quality and hydrologic control. Fringe forested and emergent wetlands and ponds serve to retain sediments and nutrients during high water events. They benefit downstream water quality although it remains degraded due to runoff from pastures, and commercial and residential stormwater. Wetlands also provide hydrologic control by storing flood waters and reducing impacts of storm events. Some individual wetlands provide unique functions.Two large forested wetlands (B10, C12) adjacent to Highway 217 provide a noise buffer and aesthetic view. Three ponds (B6,7, B8, B12) were created to mitigate for wetland fills related to adjacent development. Fishman Environmental Services page 17 Oregon Method Summary Sheet Unit 2 Lower Ash Creek Function Evaluation Description Rationale Wildlife habitat B Permanent water for wildlife is the most significant feature.

City of Tigard Wetlands December 1994 Unit 3 Upper Fanno Creek Unit 3, Upper Fanno Creek, is located in the northern end of the study area between S.W. Scholl's Ferry Rd. and S.W. Tiedeman Ave. It also includes a tributary, Hiteon Creek. Unit 3 contains approximately 32 acres of wetlands including 24.5 acres of emergent, 6 acres of forest, and 1.5 acres of open water. All of the wetlands occur adjacent to Fanno or Hiteon Creeks. The width of these fringe wetlands varies from approximately 10 feet to 400 feet wide. Fanno Creek separates residential uses on the west from industrial activities to the east. Dominant land use adjacent to Unit 3 is residential; there is also 23% industrial and 22% open space. Wetlands in Unit 5 provide 5 important functions: wildlife habitat, water quality, hydrologic control, recreation, and aesthetic quality. Fanno Creek contains a broad flood plain, up to 400 feet wide, which provides a variety of food, cover, and water resources for wildlife. The flood plain provides hydrologic control by storing flood waters and reducing peak flows. Fanno Creek provides a fishery for native species such as dace, sculpin, and sucker; native cutthroat trout have also been observed upstream. Recreational opportunities are available at Englewood Park (B1, B2, B20). Public access and a trail system are developed with views of the wetlands.

PLOT DATE. 02/10/95 City of Tigard Wetlands December 1994 Unit 4 Summer Creek and Two Unnamed Tributaries Unit 4, Summer Creek, is located in the northwest corner of the study area between SW Scholl's Ferry Rd. and Tiedeman Ave. It includes Summer Creek and 2 unnamed tributaries. Unit 4 contains approximately 75 acres of wetlands including 41 acres forest, 0.5 shrub-scrub, 16 acres emergent, and 17 acres open water. Most of the wetlands are contiguous with the exception of A5, a portion of• a tributary, which has become isolated due to residential development that culverted A6. Summer Creek is culverted at SW 135th St. and again at SW 121st St. Abundant open space occurs adjacent to Summer Creek at A2, A3 (Summer Lake Park), and B17, and E34-36 (Fowler Jr. High). The tributaries are interrupted by numerous residential road crossings and bordered by dense residential development with limited adjacent uplands. Unit 4 is one of the highest ranking wetland resource areas in Tigard. Wetlands provide 6 valuable functions: wildlife habitat, aesthetic quality, water quality, hydrologic control, education, and recreation. Summer Creek and its adjacent diverse riparian and upland forests provide water, food, cover, and dispersal opportunities for wildlife, attracting a variety of migratory and resident species. Both Summer Lake Park and Fowler Jr. High wetlands are adjacent to large upland forests which increase their wildlife habitat value. These upland sites should be preserved to the greatest extent possible. S Summer Lake provides a warm water fishery of mostly non-native species including yellow perch, large-mouthed bass, pumpkin seed, bluegill, yellow bullhead, and mosquito fish. Summer Creek contains an assemblage of native species including red-sided shiner, speckled dace, large scale sucker, and reticulated sculpin (ODFW, 1994). The Summer Creek flood plain is generally broad, up to 400 ft. wide, including a 9.5 acre pond at Summer Lake Park and 24 acres of forested wetlands in the vicinity of Fowler Jr. High. Fringe wetlands benefit water quality by trapping nutrients and sediments. The large flood plain and adjacent wetlands provide hydrologic control by storing floodwaters and reducing peak flows. Educational and recreational values are provided on 6 sites with public access and trail systems including Fowler Jr High (E34-36, B 17), Roger Hart Memorial wetland (A5), Summer Lake Park (A3), and Summer Creek greenway (A7, A10). Fowler Jr. High has received restoration grants for habitat restoration of riparian vegetation along Summer Creek. Restoration efforts have been integrated into student curriculum and include Himalayan blackberry removal, planting native trees and shrubs, irrigating and monitoring. Roger Hart Memorial wetland is maintained by The Wetlands Conservancy. Mary Woodward elementary school is adjacent to A9 and within walking distance of A3 which provides safe and excellent access. Fishman Environmental Services page 23 II/ Oregon Method Summary Sheet Unit 4 Summer Creek and Two Tributaries Function Evaluation Description Rationale Wildlife habitat A Permanent water, diverse habitat, structure, and connectivity.

Gaarde St. north to its confluence with Fanno Creek and a small portion of Fanno Creek located between SW Tiedeman Ave. and Pacific Highway (99W). Derry Dell Creek is culverted for three road crossings including SW Walnut St., SW Eden Ct., and SW Pathfinder Way. Dominant land use adjacent to Unit 5 is residential; there is also 10% open space and 10% commercial development surrounding the Fanno Creek end of the unit. Unit 5 contains approximately 9 acres of wetlands including 8 acres of forested and 1 acre of emergent wetlands. Abundant open space, approximately 23 acres, occurs adjacent to Fanno Creek (E5). Wetlands in Unit 5 provide four important functions: wildlife habitat, aesthetic quality, water quality, and hydrologic control. Wildlife habitat is limited along Derry Dell Creek due to dense development and limited adjacent uplands; its rating improves in this unit due to Fanno Creek and its broader flood plain and larger adjacent uplands which provide water, food, and cover for a variety of resident and migratory wildlife species. Derry Dell Creek flows through a residential neighborhood and provides a noise and visual buffer for residents. The Fanno Creek portion provides similar benefits between residential and industrial land uses . Fringe forested and emergent wetlands serve to retain sediments and nutrients during high water events benefiting downstream water quality. The wetlands also provide hydrologic control by storing floodwaters and reducing peak flows. 410 Fishman Environmental Services page 26 Oregon Method Summary Sheet Unit 5 Derry Dell Creek and a portion of Fanno Creek Function Evaluation Description Rationale Wildlife habitat A Permanent water with forested riparian community.

It contains 23 acres of wetlands including approximately 13 acres of forest, 8 acres of emergent, and 2 acres of open water. Signficant open space occurs adjacent to C15 where there is forested upland approximately 250 ft. on either side of the stream. Red Rock Creek flows through forested residential areas east of 72nd avenue and then through developed commercial and industrial areas. It is culverted for three major roads including Highway 217, SW Dartmouth Extension, and SW 68th Parkway. Two valuable wetlands occur in Unit 6, E28 and E30. E28 is a large 11 acre Oregon ash forest with a centrally located pond. It provides wildlife habitat as well as noise and visual buffers from Highway 217. E30 is a unique biologic community; it is a relic tufted hairgrass wetland prairie community. The wetland prairie provides educational and enhancement opportunities and should be protected from any further impacts or fill activities. Red Rock Creek corridor is generally diverse and of high value for riparian wildlife, although wildlife value was reduced due to the proximity of Highway 217 and Highway 99. �. Fringe wetlands serve to retain sediments and nutrients during high water events benefitting downstream water quality. The wetlands also provide hydrologic control by storing floodwaters and reducing peak flows. Adjacent forested hillslopes (C15) also contribute to wildlife habitat values and soil stability, preventing erosion and degradation of water quality.

Characteristic Description Physical characteristics of gently sloping topography with approximately 400' wide wetland corridor; includes watershed or basin 29 acres FO, 22 acres EM, 0.5 acre SS, and 3 acres open water. Biological information provides diverse wildlife habitat with large adjacent undeveloped uplands (E14-16, E18-21). Water quality Fanno Creek has been rated severe WO condition by DEC, (1988); degraded due to runoff from agricultural lands and commercial, industrial, and residential stormwater. Land use existing land uses within 500' of wetland edge include 30% residential, 25% open space, 22.5% commercial/industrial, and 22.5% agricultural. Fishman Environmental Services page 33 City of Tigard Wetlands December 1994 Unit 7 Middle Fanno Creek Unit 7, Middle Fanno Creek, includes the mainstem of Fanno Creek from S.W. Main St. (south of Pacific Highway (99W) southeast to S.W. Bonita Rd., two minor tributaries (E7,8, E17, E37, E38), and the mouth of Red Rock Creek south of the Southern Pacific Railroad line. Unit 7 contains approximately 54 acres of wetlands including 29 acres of forest, 22 acres of emergent, 0.5 acres of scrub-shrub, and 3 acres of open water. The width of the wetland corridor adjacent to Fanno Creek is approximately 400 feet. The tributary is a narrow wetland corridor approximately 10 to 25 feet wide. The northern third of Unit 7, west of Hall Blvd., is within the greenway of Fanno Creek Park with safe access and a paved trail system. Fanno Creek Park wetlands (E6, E9-13) separate commercial and industrial land uses on the north from residential land use south of the park. East of Hall Blvd., Fanno Creek generally travels through residential and agricultural lands. Agricultural land on the south end of the unit north of Bonita Rd. is being replaced by commercial development. E22 has been filled since the 1989 inventory. Unit 7 provides all 7 wetland functions evaluated for this project and was rated the highest for overall wetland functional values in the City of Tigard with Unit 9 (Tualatin River). The high rating of the wetlands was due to their large size, large adjacent undeveloped uplands, 1410 and public access and trail systems (Fanno Creek Park). Fanno Creek Park (E9-13) contains diverse wildlife habitat and access for recreation. Wildlife habitat also occurs in the middle of the unit east of Hall Blvd. and Fanno Creek where expansive uplands occur adjacent to the creek. The uplands include a large pasture and a large diverse mixed deciduous/coniferous woodland with two seasonal streams flowing through it. These large adjacent uplands increase wildlife habitat and aesthetic quality values of sites E14-16 and E18-21. 401 Fishman Environmental Services page e 32 r .ir:�i�7 r t� a- 1 I I I 1 I I I J �-� ■■i■■■■■ 1111■ ■■11■11►� • =- - .

Bonita Rd. south to the Oregon Electric Railroad line. It includes lower Fanno Creek and a portion of Ball creek between Interstate 5 and its confluence with Fanno Creek. All wetland sites with the exception of G15 are adjacent to the stream corridors. Unit 8 contains approximately 40 acres of wetlands including 25 acres of forest, 12.5 acres of emergent, and 2.5 acres of open water. The width of the wetland corridor adjacent to Fanno Creek is generally broad up to 600 feet wide. Ball Creek contains a much narrower, highly disturbed wetland corridor. Fanno Creek flows south beneath S.W. Durham Rd. and beyond the Unified Sewerage Agency's treatment plant to the Tualatin River. It separates residential and agricultural land use on the west from agricultural and industrial uses to the east. This reach of Fanno Creek may have the greatest development pressure within the City due to the available open space and industrial zoning. As development occurs it is essential that adequate buffers are maintained to separate distinct land uses and protect wildlife habitat from industrial disturbance. If wetlands are adversely impacted by development, wetland mitigation is required by state and federal laws. Wetland mitigation should be prioritized to occur in the flood plain in agricultural areas, if possible, to avoid impacts to forested areas. Wetland creation in the flood plain can benefit several wetland functional values including wildlife habitat, fish habitat, water quality, hydrologic control, and aesthetic quality. Abundant uplands occur adjacent to most of the wetland sites in this unit. These uplands include pastures and forests and provide wildlife habitat and natural buffers between stream and future development. A minimum 50 ft wide buffer should be preserved; wider buffers should be preserved where development can be concentrated adjacent to S.W. 74th Ave. Fishman Environmental Services page e 35 Oregon Method Summary Sheet Unit 8 Lower Fanno Creek and Lower Ball Creek Function Evaluation Description Rationale Wildlife habitat B Permanent water, diverse habitat & structure.

December 1994 Unit 9 Tualatin River Unit 9 is located in the southern end of the study area between Highway 99 and S.W. 85th Ave. in the vicinity of the Tualatin River. It contains approximately 24 acres of wetlands including 11 acres of forest, 8 acres of emergent and 5 acres of open water. Most of the sites are centered around Cook Park (F15-21, F26) which includes a mosaic of uplands and wetlands near the river, and natural, agricultural and mitigation ponds on a terrace above the flood plain. Abundant open space occurs north of the park up to approximately 1600 ft. wide. This reach also includes a small forested wetland (F22) and emergent wetland (F23) located in the flood plain upstream from Cook Park. Uplands adjacent to these upstream sites have been reduced by dense residential development on top of the hillslopes north of the flood plain. Unit 9 wetlands rated the highest with Unit 7 (Middle Fanno Creek) in the City of Tigard for overall wetland functional values. The high ratings of the wetlands are due to their large size, large adjacent uplands, and excellent public access and developed trail systems. The large expanse of diverse wetlands and uplands adjacent to the river provide excellent wildlife habitat for large and small, resident and migratory species. Natural (F15, F16), mitigation (F17-19), and agricultural ponds (F26) north and east of Cook Park also provide amphibian breeding habitat and waterfowl wintering and nesting habitat. Public parking, a boat ramp, and dock are available at the park. There are numerous soft paths that wind through the natural areas of the park and a paved bicycle trail that parallels the river. Educational opportunities are also important; Tigard High School is located immediately north and within walking distance of Cook Park. Natural areas within the park should remain undeveloped. Enhancement opportunities within Unit 9 are plentiful. Removal of Himalayan blackberry would provide an opportunity for the native shrub and understory species to develop; native species could also be planted once blackberry is removed. Fishman Environmental Services page e 38 Oregon Method Summary Sheet Unit 9 Tualatin River Flood Plain Function Evaluation Description Rationale Wildlife habitat A Permanent water, diverse habitat& structure, connectivity. Fish habitat A The Tualatin River provides habitat for cutthroat trout, stocked salmon, N. squawfish, large scale sneekers, blue gull, and largemouth bass (ODFW, 1994). Water quality A Flood plain with FO (45%) and EM (33%); fringe wetlands trap sediments and nutrients. Hydrologic control A Flood plain provides runoff&flood storage opportunities. Sensitivity to impact B Potentially sensitive. Enhancement potential A Soil is minimally disturbed; most wetlands located within 100 yr flood plain of the Tualatin River. Education A Tigard High School is located just north of Cook Park. Trails and safe access already established. Recreation A Most of Unit 9 is located in the Tualatin River Greenway or Cook Park. Public access and trails are already established. Aesthetic quality A Tualatin River Greenway contains generally a quiet, well developed riparian corridor. Characteristic Description Physical characteristics of generally flat, broad Tualatin River flood plain; includes approximately 11 acres watershed or basin FO, 8 acres EM, 5 acres OW Biological information provides fish and wildlife habitat; vegetation and habitat diverse with excellent interspersion. Water quality Tualatin River has been rated severe WO condition by DEQ (1988). Land use existing land uses within 500' of wetland edge include 67% agricultural and 33% open space.

It includes two small tributaries that flow through residential neighborhoods directly into the Tualatin River, an isolated stormwater detention pond (F24), and four isolated golf course ponds (F13-14, F1-2). One of the tributaries is unnamed (F3-8). It originates on the golf course north of Durham Rd. and flows south through a forested riparian corridor to the river. The stream contains a narrow floodplain with fringe emergent and forested wetlands. Abundant upland forests and agricultural lands occur adjacent to the stream. Copper Creek (F25) is a narrow riparian corridor dominated by western red cedar and red alder. It flows through a densely developed residential neighborhood. Both tributaries have no public access and consequently rate low for educational and recreational values. The unnamed tributary is less developed and consequently provides greater wildlife and aesthetic values. Future development in this area needs to protect water resources and wildlife travel corridors. Buffers along this stream should be placed a minimum of 50 ft from the wetland edge or 25 ft from the top of the hillslope adjacent to the floodplain to prevent erosion and water quality declines in the stream. P. ip, Fishman Environmental Services page 41 Oregon Method Summary Sheet Unit 10 Short Tributaries to the Tualatin River Function Evaluation Description Rationale Wildlife habitat A Permanent water, diverse habitat & structure, connectivity. Fish habitat B Tributaries provide potential fish habitat. It is unknown whether fish are present. Water quality A Unnamed tributary's fringe wetlands trap sediments and nutrients. Hydrologic control A Stream corridor provides runoff & flood storage opportunities. Sensitivity to impact B Potentially sensitive. Enhancement potential A Soil is minimally disturbed; wetlands connected by stream. Education C No access; no schools adjacent; unlikely to be used for education.

It contains approximately two acres of wetlands and a narrow stream corridor: Mallard Lakes ponds (F9,10), agricultural ponds (F11,12), and Pinebrook Creek (F22). Mallard Lakes development ponds have been created by damming the headwaters to Pinebrook Creek. The ponds contain a variety of emergent vegetation and are surrounded by a narrow fringe of trees, shrubs, and mowed lawn. Even though the ponds are isolated by dense residential development, they provide wildlife habitat and attract mallards, belted kingfisher, and other riparian species. These ponds provide recreational and educational opportunities for the neighborhood; a walking trail circles F10 and connects to an unmaintained trail that winds downstream along Pinebrook Creek. The seasonal agricultural ponds provide limited wildlife habitat, recreational and educational values due to the presence of cattle. Pinebrook Creek contains a narrow riparian corridor. The forest canopy is dominated by western red cedar and red alder; the understory contains limited vegetation due to uncontrolled trail use. Fishman Environmental Services page 44 Oregon Method Summary Sheet Unit 11 Pinebrook Creek and farm ponds, neighborhood ponds Function Evaluation Description Rationale Lee Wildlife habitat B Permanent water and a forested riparian canopy are significant habitat features. Detractors are limited vegetation diversity and structure. ✓,, Fish habitat B Pinebrook Creek and Mallard Lakes Pond provide potential fish habitat. It is unknown whether fish are present. It is unlikely fish are in Pinebrook Creek. ✓' Water quality B Stream corridor is a residential area. G,/ Hydrologic control B Stream corridor provides runoff and flood storage opportunities. Sensitivity to impact B The ponds are created or severely impacted by cattle. The stream corridor has been impacted by pedestrian use. Enhancement potential B Soil compacted due to pedestrians (F-27), cattle (F-11, F-12) and creation (F-9, F-10). Education B No schools in the vicinity. Mallard Lakes Pond may be used by neighborhood for education. Recreation B Neighborhood use; trail (F-27) developed trail (F-9, F- 10). Aesthetic quality B Limited garbage, natural sounds and odors dominate. Characteristic Description Physical characteristics of moderate gradient stream; includes approximately 2 acres of open water wetlands watershed or basin and a stream corridor. Biological information provides fish and wildlife habitat; food, cover, and water resources are present Water quality degraded due to residential stormwater runoff. Land use existing land use within 500 ft of wetland edge includes 75% residential and 35% agricultural. Fishman Environmental Services page 45 City of Tigard Wetlands December 1994 3.3 Task 4: Significance Criteria The determination of resource site significance will be the first task in Phase 2 of the Tigard Goal 5 study. This section discusses proposed methods for determining significance, and the use of the inventory information in that task. The first step in determining resource unit significance is to identify resource areas that are already determined "significant" in city code or plan documents. For resource areas that are already determined to be significant, the Project Team will document the environmental and social factors that make those areas significant. Significance determination for remaining units will be based on an evaluation of environmental and social values. The following Values are proposed for discussion and consideration for determining significance of resource units: Environmental Values El. The unit contains state or federal categorized species (or critical habitat) or physical feature. A unit is significant if it contains any plant or animal species, or critical habitat for such, that is categorized on a state or federal sensitive, rare, threatened or endangered list. This value also applies to physical features that are categorized by local, state or federal agencies; examples could include: scenic river, geologic area of significance, etc. E2. The unit contains native plant communities exhibiting high ecological integrity. Relatively undisturbed native plant communities with few or no non-native plants are rare. E3. The unit has medium or high wildlife habitat value. This should be based on a standard assessment protocol, such as the WHA; the rating ranges for "medium" and "high" need to be determined. • Fishman Environmental Services page 46 City of Tigard Wetlands December 1994 E4. The unit provides water quality or hydrology functional values. Resource units that provide water quality protection to receiving streams, and/or stormwater storage that is cumulatively important within the watershed are important. ES. The unit is important for ecosystem integrity or function. Units are significant if they provide ecosystem linkage or continuity, allow wildlife passage between larger habitat units or genetic flow between plant populations, provide critical habitat for certain life history stages of sensitive fish and wildlife species, or other functions at the watershed or ecosystem level. Social Values Si. The unit provides educational value that is medium or greater (including potential value). Units are significant if they provide educational opportunities for local schools, or research opportunities for the scientific community. This value is dependent on accessibility and distance from schools. S2. The unit has scenic or buffering qualities that rate medium to high. Rating of scenic quality is fairly subjective, and is based on visual characteristics. Buffering qualities refer to visual, noise and air quality protection. S3. The unit provides medium to high opportunity for passive recreation. The rating for recreational opportunity is based on a combination of accessibility, medium or high environmental or scenic value, and low probability that recreational use will adversely affect environmental or scenic values. Specific criteria need to be agreed upon for each of the values listed above. Evaluation for several of these values can be based on the functional value ratings derived for Tigard units using the Oregon Method. The Oregon Method by itself does not provide ratings of 1 Fishman Environmental Services page 47 City of Tigard Wetlands December 1994 significance. The results summarized in Table 3.2-1 can not really be used to compare units and conclude that some are significant and others are not. Each unit must be considered on its own values, using the Oregon Method results where appropriate. There is a tendency to draw conclusions from a summarization such as Table 3.2-1 about the significance of individual units. Unit 11, for example, is small (2 acres) and scored "B" for every function ("B" means the unit has potential to provide the function, or provides the function in a limited way). Unit 7, on the other hand, is large (54 acres) and scored "A" for 8 of the 9 functions ("A" means the unit provides the function). Is Unit 7 significant and Unit 11 not significant? This is not necessarily the case, and each unit needs to be considered within a framework such as the Values presented above to determine significance.
