The purpose of the visit was for the Corps to make a jurisdictional determination on the wetlands on the site and to confirm the wetland delineation. Ecology was informally asked by the Corps to provide technical support on the field visit. Ecology found that the delineation was accurate, as shown in the "Springbrook Creek Mitigation Site Wetland Delineation Report", and as indicated by flags hung in the field to indicate the wetland edge. We also concur with the jurisdictional determination letter sent by the Corps to WSDOT on April 21, 2005. This letter is provided at the request of the I-405 Corridor Program. Ecology does not have an official pre -application jurisdictional determination process but we do provide pre -application delineation confirmations at the request of the applicant. We also typically confirm the wetland delineation as part of the application review process. If you have any questions, please contact Kim Harper at (425) 649-7004 or via email at khar461 @ecy.wa.gov.

The I-405 Corridor, from I-5 in Tukwila to 1-5 in Lynnwood, needs improvement to relieve current and future traffic congestion. The I-405 Corridor Program is a set of improvements to the I-405 Corridor designed to address congestion on this important arterial. The proposed improvements will result in some environmental impacts, some of which will be addressed through a mitigation program called Early Environmental Investment (EEI). What is EEI? Early Environmental Investment develops mitigation in advance of project impacts. The EEI process will identify, rank, select, design, and permit environmental investment for improving aquatic resources, fish habitat, wetlands, water quantity, and floodplains. This advance selection and creation of mitigation will allow the resources longer to mature before actual project impacts are incurred, reducing the length of time that resource functions are affected. EEI is a cooperative effort, requiring information sharing and partnering among agencies with an interest in the I-405 study area. How does this report support EEI? This report is an investigation of one mitigation site selected under the EEI process. The report provides detailed baseline wetland information on the proposed Springbrook mitigation site. A separate mitigation report will be prepared to discuss details of the proposed mitigation activities at this site. Where is the EEI Mitigation Site located? The Proposed Springbrook Mitigation Site consists of five units (A through E, See Figure 1). All five units are within the City of Renton, Washington: Unit A is located southwest of the intersection of SW 27th Street and Lind Avenue SW. It extends approximately 1,200 feet south from the intersection, and approximately 900 feet west to Springbrook Creek. Unit A is in Section 30, Township 23 North, Range 5 East (Willamette Meridian). Unit B is located southeast of the intersection of SW 270' Street and Oakesdale Avenue SW (Section 25, Township 23 North, Range 4 East). It extends approximately 1,200 feet south from the intersection, and approximately 1,200 feet east to Springbrook Creek. Unit C is located west of Oakesdale Avenue SW, between SW 27th Street and SW 34th Street (Section 25, Township 23 North, Range 4 East). It extends west from Oakesdale Avenue SW to the Burlington Northern Santa Fe (BNSF) Railroad right-of-way. Unit D is located north of SW 43rd Street, immediately east of the BNSF right-of-way (Section 36, Township 23 North, Range 4 East). It extends approximately 1,300 feet north of SW 43rd Street, and approximately 350 feet east of the BNSF right-of-way. Unit E is a triangular parcel located east of Oakesdale Avenue SW, approximately 400 feet south of SW 34th Avenue (Section 25, Township 23North, Range 4 East). Springbrook Creek forms the southeast boundary of Unit E. Springbrook Creek Mitigation Site Wetland Delineation Report g p Washington State -/' Department of Transportation January 2005 How was the wetland study for EEI conducted? The investigation included two steps. The first step was a review of existing documents such as soil surveys, aerial photographs, and other available documents. The second step was the field investigation, delineation, and classification of the wetlands observed on the units. Step 1: Review of Existing Information Existing documents that were reviewed for this study included but were not limited to: • Soil Survey of King County Area, Washington (Snyder et al. 1973 ) • Springbrook Creek Wetland and Habitat Mitigation Bank Prospectus (Washington State Department of Transportation 2004) National Wetland Inventory Web site (http://wetlandsfws.er.usgs.gov/wtlnds/launch.html) (USFWS 2004) These documents provide background information on the soils, hydrology, topography, land use, wetlands, streams, and wildlife habitat in the site vicinity. Step 2: Field Investigation Wetland delineations were made using the methods described in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology [Ecology] 1997) and the Corps of Engineers Wetland Delineation Manual (U.S. Army Corps of Engineers 1987). Areas were identified as wetlands if they displayed the necessary soils, plants, and hydrologic conditions. A detailed description of the field methodology used in this study is provided in Appendix A of this report, and the wetland delineation data sheets are presented in Appendix B. Delineated wetlands were classified according to the U.S. Fish and Wildlife Service (USFWS) Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979). The City of Renton wetland rating system (Renton Municipal Code Title 4, Chapter 3, Section 4.3.050) was used to rate wetlands. Table 1 summarizes the wetland rating criteria utilized.

Unit A Field investigations were performed by project biologists at Unit A on October 20, 2004, and additional data were collected on October 21 and 28, 2004. One wetland (A-1) was delineated within the unit. A summary of the findings at Unit A are presented below. Springbrook Creek Mitigation Site Wetland Delineation Report T WashingtonID"artnrat S at Transportation January 2005 Wetland A-1 Palustrine forested, scrub/shrub, and emergent Category 3 22.9 acres in Unit A/24 acres overall Wetland A-1 is riverine wetland located in a low lying area between adjacent roads, developed areas elevated by fill material, and the maintained berm along Springbrook Creek. Wetland A-1 is approximately 24 acres in size, and includes palustrine forested, scrub/shrub, and emergent communities (Cowardin 1979). The forested areas comprise a fringe along the northern, southern, and western edges of Wetland A-1, although portions of the forested component extend into the middle of the unit. The scrub/shrub communities occur as smaller (approximately 0.2 to 1.5 acre) areas scattered throughout the forested and emergent communities. The emergent community covers the eastern %2 of Unit A. Vegetation in the forested areas includes red alder (Alnus rubra) and black cottonwood (Populus balsamifera) in the canopy. These trees are relatively low (generally less than 75 feet tall), with diameters at breast height (dbh) up to approximately 24 inches. The understory includes Pacific willow (Salix lucida var. lasiandra) and Himalayan blackberry (Rubus armeniacus). Reed canarygrass (Phalaris arundinacea) is the dominant herbaceous species and occupies the emergent areas. Soils in Wetland A-1 are mapped as Snohomish silt loam, Woodinville silt loam, and Puget silty clay loam (Snyder et al. 1973). The soils observed in wetland test pits were generally very dark grayish brown (I OYR 3/2) silty clay or silty clay loam. Fine mottling was common in most areas. Wetland A-1 is separated from Springbrook Creek by a maintained berm located approximately 20 feet above the water level. Two small ditches, referred to herein as the northern and southern ditches, traverse Wetland A-1 from east to west. The northern ditch crosses the middle of the unit beginning near Lind Avenue SW and extending to the eastern foot of the berm along Springbrook Creek. A culvert carries it under the berm. This ditch is approximately 6 feet wide and 10 inches deep, and reed canarygrass lines the channel and dominates the substrate. The southern ditch is located just north of the south property boundary. The ditch begins at a culvert under Lind Avenue SW, and flows west to Springbrook Creek, where it passes through the berm. The southern ditch is approximately 10 to 15 feet wide, and appears to consist of a series of loosely connected areas of shallow inundation. The banks are vegetated with alder, cottonwood, and willows, which provide shade and contribute to organic material. A culvert carries water from the south directly into Wetland A-1. Wetland hydrology in Wetland A-1 appears to derive from elevated groundwater from Springbrook Creek and stormwater flows entering the wetland from culverts to the east and south. Areas of saturated soils and shallow inundation were observed during the field investigations. Fill berms adjacent to the sidewalks along Lind Avenue SW and SW 27t' Street extend down to the wetland edge. These areas are dominated by dense thickets of Himalayan blackberry and likely consist of fill material placed when these roads were constructed. With the exception of a few undeveloped areas, the majority of the parcels surrounding Wetland A-1 are developed (see Figures 1 and 2). An undeveloped lot, potentially consisting of a wetland, is located north Springbrook Creek Mitigation Site Wetland Delineation Report TwW"~M�- ,o„ January 2005 _4 IL I1� r 9 r A. -Y Mel. s i�a�- `w _V. tv� x W, --w AL 8 0 ! i tv -A 2- 9L A 0 VA, A i[i4ll Z Unit A Wetland Delineation 14*4t Parcel Surveyed Wetland Interpreted (off -site) Wetland N 11v Data Plot 0 100 Oet of SW 27th Street and east of Springbrook Creek. Due to the presence of the street, this area is not directly connected to Wetland A-1, although it likely was in the past. The parcel south of Wetland A-1 along Lind Avenue SW includes a large building and parking areas. A small stormwater treatment feature, approximately 50 feet wide, is associated with this development and is located between the parking areas and Wetland A-1. Until recently, the parcel to the southwest of Unit A contained maintained pasture grass. This pasture is currently being graded for development. The western boundary of Unit A includes the channelized portion of Springbrook Creek. A large wetland complex is located immediately west of Springbrook Creek (see Unit B description). In summary, Wetland A-1 is a large system comprised of multiple vegetation types that contribute to relatively high function. However, its buffers are narrow and disturbed, limited in size and function by surrounding land uses. Although Wetland A-1 is surrounded on three sides by development, a berm adjacent to Springbrook Creek forms the fourth side and is relatively undisturbed. Springbrook Creek provides a hydrologic connection to other habitats upstream and downstream of the site, as well as areas along the BNSF right-of-way and the Green River. Unit B Project biologists delineated three wetlands (B-1, B-2, and B-3) in Unit B on October 19, 2004. Additional data were collected on October 20, 2004. A summary of the wetland investigations is provided below. Wetland B-1 Palustrine forested and emergent Category 3 22.3 acres in Unit B/22.3 acres overall Wetland B-1 a depressional wetland approximately 22.3 acres in size and includes palustrine forested and emergent communities (Cowardin 1979). The forested areas comprise a fringe along SW 27 h Street and Oakesdale Avenue SW, and also occupy the southern third of the wetland (See Figures 1 and 3). The emergent community occupies the northeastern third of the wetland. Vegetation in the forested areas includes red alder (Alnus rubra) and black cottonwood (Populus balsamifera) in the canopy, with an understory of Pacific willow (Salix lucida var. lasiandra), Scouler's willow (Salix scouleriana), Himalayan blackberry (Rubus armeniacus), and red osier dogwood (Corpus sericea). Herbaceous species in the forested areas include bittersweet nightshade (Solarium dulcamara), scouring rush (Equisetum hymale), English ivy (Hedera helix), and hedge bindweed (Convulvulus sepium). Trees in Wetland 13-1 are relatively short (the tallest are approximately 75 feet), with diameters at breast height (dbh) up to approximately 24 inches. Emergent portions of Wetland 13-1 are dominated by reed canarygrass (Phalaris arundinacea), although yellowflag iris (Iris pseudacorus), common cattail (Typha latifolia), creeping buttercup (Ranunculus repens), waterpepper (Polygonum hydropiper), and mild waterpepper (Polygonum hydropiperoides var. hydropiperoides) are locally dominant. Soils in Wetland B-1 are mapped as Woodinville silt loam (Snyder et al. 1973). The observed soils were generally dark to very dark grayish brown (IOYR 4/2 to 1 OYR 3/2) silty loam to silty clay loam. Fine mottling was common in most of the sample plots. Springbrook Creek Mitigation Site Wetland Delineation Report T ���,� ;mponatbn January 2005 lid -Tom '- x o.

Topography within the wetland is quite flat, with a few micro -depressions that trap water. Wetland B-1 is separated from Springbrook Creek by a berm (the Oakesdale Avenue Mitigation Site) and by Wetland B-2. A culvert appears to carry water into Wetland B-1 from the west under Oakesdale Avenue SW; however, no flow was observed during the field investigation and there was no evidence of a channel. Shallow areas of inundation were found along the eastern side of Wetland B-1 near the Oakesdale Avenue SW Mitigation Site. Water appears to directly enter Wetland B-1 as precipitation, and via elevated groundwater levels. In addition to Wetland B-1, two other wetlands (B-2 to the east and B-3 to the north) are located in Unit B. Two vacant parcels (a Boeing site and Unit C) are located to the west of Wetland B-1 on the opposite side of Oakesdale Avenue SW. Southwest 27`h Street is located to the north of Wetland B-1, and the properties to the north of the road are occupied by commercial buildings. A newly built strip -mall is located south of Wetland B-1. Vegetation along the road edges is dominated by domestic grasses and non-native fortis. Himalayan blackberry is prevalent along edges and in disturbed areas. Wetland B-1 is a relatively large wetland with multiple habitat types. These habitats are fragmented by roads and development, and the natural vegetation has been altered significantly. Buffers are narrow and disturbed, except on the east. Wetland B-2 Palustrine forested and emergent Category 3 10 acres in Unit B/10 acres overall Wetland B-2 is a riparian wetland 10 acres in size, and includes palustrine forested and emergent communities (Cowardin 1979). The forested area dominates the majority of the wetland, and the emergent areas are located in the northeast and northwest corners of the wetland (see Figures 1 and 3). Vegetation in the forested area is dominated by Pacific willow, although Oregon ash (Fraxinus latifolia) is present in the northern portion of the forested area. Red osier dogwood is the dominant understory plant, although Himalayan blackberry is also present. Herbaceous species in the forest include reed canarygrass, bittersweet nightshade, and hedge bindweed. Stinging nettle (Urtica dioica) and yellowflag iris (Iris pseudacorus) are also common in some areas. Emergent portions of Wetland B-2 are dominated by reed canarygrass, but common cattail (Typha latifolia), and mild waterpepper are also present in areas with seasonal ponding. Soils in Wetland B-2 are mapped as Woodinville silt loam (Snyder et al. 1973). The soils observed in Wetland B-2 are similar to those found in Wetland B-1 (dark to very dark grayish brown silty loam to silty clay loam with fine mottling). Wetland B-2 is located in a depression bordered by SW 27`h Street to the north, developed areas (fill) to the south, and berms to the east and west. The topography of Wetland B-2 is relatively flat, with a few micro -depressions that trap and hold water. Shallow inundated areas were found in the northern third of Wetland B-2. Wetland B-2 is separated from Springbrook Creek by a maintained berm. A small ditch begins in the forested area on the northern third of Wetland B-2. The ditch extends through the berm to Springbrook Creek. This ditch effectively drains the northern portion of the wetland. Springbrook Creek Mitigation Site Wetland Delineation Report T w o; ate Department Tnnaportntlon January 2005 10 A culvert on Springbrook Creek upstream of Unit B has historically constricted flow of the stream, resulting in flooding of adjacent areas. To alleviate this and associated upstream flooding north of SW 271h Street, the culvert under the road was recently replaced (1999). This replacement subsequently removed the constriction of flow through Springbrook Creek. Since this constriction has been removed, the impact of Springbrook Creek on the hydroperiod of Wetland B-2 is unclear. The remaining buffers of Wetland B-2 are somewhat wider than those of Wetland 13-1. The Oakesdale Avenue SW Mitigation Site and Wetland 13-1 are located to the west of Wetland B-2, and Springbrook Creek and Wetland A-1 are located to the east. The northern edge of Wetland B-2 extends to the fill slope of SW 27th Street, which is dominated by domestic grasses, non-native forbs, and Himalayan blackberry. New construction is located to the south of the wetland, and associated parking surfaces extend nearly to the wetland edge. Wetland B-2 is a relatively large wetland with multiple habitat types. The system provides a connection between Wetlands 13-1 and A-1, as well as to other habitats along Springbrook Creek, the BNSF Railroad, and the Green River. Wetland B-3 Palustrine forested Category 3 0.3 acre in Unit B/0.3 acre overall Wetland B-3 is a relatively small (0.3 acre) palustrine forested wetland (Cowardin 1979). It is located in a swale between Wetland B-1 and SW 27`h Street, and extends west to Oakesdale Avenue SW (see Figures 1 and 3). Vegetation in Wetland B-3 is similar to the forested portions of Wetland 13-1 and includes a canopy of red alder and Pacific willow, with red osier dogwood in the understory. Himalayan blackberry is also present, particularly in the eastern half of the wetland, and on the road prism of SW 276' Street. Herbaceous vegetation in Wetland B-3 is sparse, although scattered reed canarygrass and common horsetail (Equisetum arvense) are present. Soils in Wetland B-3 are mapped as Woodinville silt loam (Snyder et al. 1973), and the observed soils are similar to those found in Wetland B-1, although some gravels are present. Wetland B-3 is separated from Wetland 13-1 by a berm. It is unclear whether Wetland B-3 was excavated and the berm constructed from the excavated material, or if the berm was constructed from fill material from some other location. Water in Wetland B-3 appears to be provided by runoff from SW 27`h Street. Groundwater may also play a role in the hydrology of this wetland. The buffers for Wetland B-3 include Wetland 13-1 to the south and the fill slopes for Oakesdale Avenue SW and SW 27`h Street to the west and north. The eastern buffer is predominantly Himalayan blackberry, and extends along SW 270' Street to the Oakesdale Avenue SW Mitigation Site. The northern and western buffers are narrow (less than 20 feet wide), limited by the presence of the roadways. Wetland B-3 is small and subject to frequent disturbance. Trash is common in the wetland and its buffers. As a result, it provides little habitat for wildlife, and likely has low relative value. Springbrook Creek Mitigation Site Wetland Delineation Report T wWs.hkDeport,9t- ;tat. t,„,� January 2005 11 Unit C Project biologists delineated three wetlands (C-1, C-2, and C-3) in Unit C on October 22, 26, 27, and 28, 2004 and on November 2, 3, and 5, 2004. A summary of these wetlands is provided below. Wetland C-1 Palustrine forested and scrub/shrub Category 2 21.2 acres in Unit C/33.9 acres overall Wetland C-1 is a palustrine forested-scrub/shrub depressional wetland (Cowardin 1979) approximately 33.9 acres in size, 21.2 acres of which are within Unit C. Wetland C-1 is located along the north and east sides of Unit C, and extends northward onto Boeing property (see Figures 1 and 4). Pockets of scrub - shrub communities occur within the larger forested community. Most of these shrub communities have hydric soils and are dominated by wetland vegetation, although there are several small areas of fill material within the larger wetland matrix vegetated by monocultures of Himalayan blackberry. Vegetation in Wetland C-1 includes a canopy of red alder (Alnus rubra) and black cottonwood (Populus balsamifera), with an understory of Sitka willow (Salix sitchensis), red osier dogwood (Cornus sericea), and hardhack (Spiraea douglasiz). Herbaceous species in the forested areas include a mixture of creeping buttercup (Ranunculus repens), bittersweet nightshade (Solanum dulcamara), and reed canarygrass (Phalaris arundinacea). Shrub communities in Wetland C-1 include Pacific willow (Salix lucida var. lasiandra), red osier dogwood, hardhack, and Himalayan blackberry (Rubus armeniacus). Soils in Wetland C-1 are mapped as a mixture of Woodinville silt loam and Puyallup fine sandy loam (Snyder et al. 1973). The soils observed in wetland test pits were generally dark grayish brown (IOYR 4/2) silt loam with fine mottling. Previous studies (Parametrix 2002) indicate that some portions of Wetland C-1 may be comprised of fill material. Wetland C-1 appears to receive water from precipitation and from elevated groundwater levels. A ditch crosses Wetland C-1 near the northern property line, but does not appear to provide water to Wetland C-1. Rather, this ditch appears to have been constructed to convey water away from Wetland C-1 and under Oakesdale Avenue SW through a culvert north of Unit C. A shallow swale with no defined channel does cross the central portion of Wetland C-1, traveling from north to south. This swale appears to be a remnant of the original drainage shown on the soil survey (Snyder et al. 1973). Wetland C-1 extends east to the edge of the fill prism of Oakesdale Avenue SW. The road slope is dominated by a dense thicket of Himalayan blackberry adjacent to the wetland. Closer to Oakesdale Avenue SW, the right-of-way consists of mowed grasses with disturbance -tolerant forbs (lance -leaf plantain [Plantago lanceolata], tansy [Tanacetum vulgare], teasel [Dipsacus sylvestris], and thistle [Cirsium vulgare]). North of Unit C, Wetland C-1 includes emergent areas dominated by reed canarygrass and disturbed upland meadows. The area immediately west of Wetland C-1 is primarily Himalayan blackberry, grading into the emergent portion of Wetland C-2. The areas to the south of Wetland C-1 include dense thickets of Himalayan blackberry and Scot's Springbrook Creek Mitigation Site Wetland Delineation Report January 2005 AML - - ON- Waehington State Dw"rm ant of Tr sport."b 12 7SW 2MH SLV WA �e .0 r • /� � ` � - � I .� 1I. n,. t-niJr'����� 1� .'

Wetland C-1 is a relatively large wetland with multiple habitat types. Songbirds and raptors (likely red- tailed hawks) were observed in the wetland and in the adjacent uplands, and a raptor next was observed. Coyotes were also observed in this area. Connectivity to other habitats is very good, making this a desirable location for restoration. Wetland C-2 Palustrine forested and emergent Category 3 5.8 acres in Unit C/48.5 acres overall Wetland C-2 is a palustrine forested and emergent depressional wetland (Cowardin 1979) approximately 48.5 acres in size; 5.8 acres of Wetland C-2 are within Unit C. The forested area occupies the eastern and southern portion of wetland C-2, and the emergent community occurs in the west alongside the BNSFRR right-of-way (Figures 1 and 4). Vegetation in the forested area is dominated by black cottonwood and Pacific willow (Salix lucida var. lasiandra) with an understory of Scouler's willow (Salix scouleriana), red osier dogwood, and Himalayan blackberry. The emergent community is dominated by reed canarygrass. Soils in Wetland C-2 are mapped as Woodinville silt loam and Puget silty clay loam (Snyder et al. 1973). The soils observed in Wetland C-2 are dark grayish brown silt loam with medium-sized mottles. As noted above, portions of Wetland C-2 may include fill soils (Parametrix 2002). Topography in Wetland C-2 is relatively flat and evenly sloped, although hummocks are present in emergent areas. Wetland C-2 appears to receive water from precipitation and from elevated groundwater levels. A north -south running ditch divides the forested portions of Wetland C-2 from the emergent communities. This ditch continues north beyond the wetland boundary before turning east and entering Wetland C-1. As noted in the description of Wetland C-1, the ditch appears to have been constructed to convey water away from Unit C. Wetland C-2 extends to the edge of the BNSF right-of-way on the west. The vegetation to the north of Wetland C-2 is dominated by Himalayan blackberry. A large, disturbed upland is located to the east of Wetland C-2 (see description of upland west of Wetland C-1). Wetland C-2 extends south beyond the boundary of Unit C with similar vegetation communities throughout the system. Wetland C-2 is a large wetland with multiple habitat types. Songbirds, raptors, and coyotes were observed in Wetland C-2 and in the adjacent uplands. As noted for Wetland C-1, connectivity to other habitats is very good, making this a desirable location for restoration. Springbrook Creek Mitigation Site Wetland Delineation Report T Washington D*partrnent St�anaportation January 2005 14 Wetland C-3 Palustrine forested Category 3 0.9 acres in Unit C/48.5 acres overall Wetland C-3 is a palustrine forested depressional wetland (Cowardin 1979). It is connected to Wetland C-2, and the wetland complex extends offsite to the south. The total size is approximately 48.5 acres (including Wetland C-2), but the portion of Wetland C-3 in Unit C is approximately 0.9 acre. It is located in the southern -central portion of Unit C, north of the BNSF warehouse on Oakesdale Avenue SW (Figures 1 and 4). Wetland C-3 extends offsite to the south and west, and appears to be connected to Wetland C-2 beyond the Unit boundary. Wetland C-3 has a canopy of black cottonwood and Pacific willow, with an understory of red osier dogwood, Himalayan blackberry, and Sitka willow. Herbaceous vegetation is largely absent. Soils in Wetland C-3 are mapped as Puyallup fine sandy loam (Snyder et al. 1973). The observed soils are dark grayish brown gravelly loam with fine mottling. Soils in Wetland C-3 may include fill as noted in Wetlands C-1 and C-2 (Parametrix 2002). A small drainage formerly traversed Unit C, but it appears to have been buried by subsequent activity on the site. This buried drainage may still provide subsurface water to Wetland C-3. Other potential sources of water include direct precipitation and elevated groundwater levels. A large disturbed upland is located to the north and west of Wetland C-3. This upland is several feet higher than the surrounding wetland and appears to be comprised primarily of fill material. Vegetation in the upland is dominated by invasive species including Himalayan blackberry and Scot's broom, with mixed grasses and disturbance -tolerant forbs (see description of southern buffer for Wetland C-1). A disturbed emergent wetland community (primarily bentgrass sp.) is located to the south of Wetland C-3, and a commercial/light industrial site with associated parking is located to the southeast of Wetland C-3. Although Wetland C-3 is small and relatively disturbed, it provides a valuable pocket of habitat bordered on one side by an industrial area. Wetland C-3 is connected to other relatively large wetlands and uplands to the north and south, and the nearby BNSF right-of-way provides a linear corridor connecting Wetland C-3 to other habitats. Unit D Project biologists visited Unit D on October 21, 2004, and delineated one wetland (D-1). A summary of Wetland D-1 is provided below. Wetland D-1 Palustrine forested, scrub/shrub, and emergent Category 2 5.6 acres in Unit D/6.7 acres overall Wetland D-1 is approximately 6.7 acres in size; 5.6 acres of the wetland are in Unit D (Figures 1 and 5). The wetland includes palustrine forested, scrub/shrub, and emergent communities (Cowardin 1979). The forested areas are located primarily along the BNSF right-of-way and to the south. Portions of the forested wetland extend north off of the site. The emergent community covers the eastern and northern portions of Wetland D-1. Springbrook Creek Mitigation Site Wetland Delineation Report ITOW " January 2005 15 a 0 i . i ;OAS AK_ `rJ' 1 Unit D Wetland Delineation Parcel ! _ Surveyed Wetland N f Q Interpreted (off -site) Wetland W�E f Data Plot S 0 200 400 Feet Vegetation in the forested areas includes red alder (Alnus rubra) and black cottonwood (Populus balsamifera); Pacific willow (Salix lucida var. lasiandra) and Oregon ash (Fraxinus latifolia) in the canopy; and salmonberry (Rubus spectabilis), red osier dogwood (Corpus sericea), and hardhack (Spiraea douglasii) in the understory. Reed canarygrass (Phalaris arundinacea), lady fern (Athyrium frlix femina), and creeping buttercup (Ranunculus repens) are the dominant herbaceous species. Vegetation in the emergent community is dominated by reed canarygrass, common cattail (Typha latifolia), and mild waterpepper (Polygonum hydropiperoides var. hydropiperoides). Wetland D-1 is situated in a depression with relatively steep slopes to the east and west. Topography within Wetland D-1 is flat, with a few micro -depressions and many hummocks in the emergent area. Soils in Wetland D-1 are mapped as Snohomish silt loam and Puget silty clay loam (Snyder et al. 1973). The soils observed in test pits were generally grayish brown (IOYR 5/2) silty clay to silty clay loam. Fine mottling was common in most areas. Water appears to enter Wetland D-1 directly as precipitation, and via elevated groundwater. Several areas of bare earth with cracked soil were observed in the emergent areas. Wetland D-1 occupies the majority of Unit D. The southern third of the unit includes an existing mitigation site, which is bordered on the north by a dense thicket of Himalayan blackberry (Rubus armeniacus). East of Wetland D-1, a narrow, mowed area with planted shrub (primarily oceanspray [Holodiscus discolor] and red osier dogwood) separates the wetland from adjacent parking and commercial buildings. The southeastern buffer is dominated by black cottonwood with a dense understory of Himalayan blackberry. On the west, Wetland D-1 extends to the edge of the maintained BNSF right-of-way. A railroad spur and several undeveloped parcels owned by the railroad complete the northern buffer. Wetland D-1 is a relatively large wetland with multiple vegetation types. The buffers are disturbed, particularly those to the east and west; however, those to the north and south contain relatively extensive areas of open space. The BNSF right-of-way provides connections to other habitats to the north and south. Unit E Unit E is a triangular parcel located east of Oakesdale Avenue SW, approximately 400 feet south of SW 34`h Avenue in Renton (Section 25, T23N, R4E). No wetlands were identified on this parcel (Figure 1). The flooded fringe of Springbrook Creek does conform to the wetland definition, however, and is discussed below. Unit E was filled within the last 20 years. The site is roughly 15 feet higher in elevation than the adjacent creek. Unit E is vegetated with ruderal species and colonizing trees and shrubs. Along the stream banks, red alder trees have established a well -developed canopy over most of this section of stream. The understory is dominated by reed canarygrass and Himalayan blackberry. The flooded fringe of the creek is completely dominated by reed canarygrass. Soils are composed of gravelly sandy loam that was placed as fill, and silt loam may represent historic floodplain soils. Hydrology is primarily maintained by the surface water of Springbrook Creek.

Springbrook Creek Mitigation Site Wetland Delineation Report 7 oopmt.State ertof Transportation January 2005 18 Appendix A - Wetland Delineation Methodology Wetlands are defined as areas saturated or inundated by surface or groundwater at a frequency and duration sufficient to support, and which under normal circumstances do support, a prevalence of vegetation adapted for life in saturated soil conditions. The methods used to delineate the on -site wetlands conform to methods in Washington State Wetland Identification and Delineation Manual (Ecology 1997). All delineated wetlands were instrument -surveyed and mapped on project base maps. Field data sheets for wetlands are provided in Appendix B. To be considered a wetland, an area must have hydrophytic vegetation, hydric soils, and wetland hydrology. HDR Engineering, Inc. staff collected data on these parameters in areas representative of typical site conditions. Staff collected additional data in associated uplands as needed to confirm wetland and stream boundaries. The wetland boundaries were delineated with numbered, bright pink flagging. Boundaries were numbered in the order in which they were encountered in the field, and numbering does not necessarily reflect geographic location. Vegetation The dominant plants and their wetland indicator status were evaluated to determine if the vegetation was hydrophytic. Hydrophytic vegetation is defined as vegetation adapted to wetland conditions. To meet the hydrophytic vegetation criterion, more than 50 percent of the dominant plants must be Facultative, Facultative Wetland, or Obligate, based on the wetland indicator category assigned to each plant species by USFWS (Reed 1997). Table A-1 lists the definitions of the indicator categories. Table A-1. Definitions of Wetland Plant Indicator Categories used to Determine the Presence of Hydrophytic Vegetation Wetland Indicator Category Symbol Definition Obligate Wetland Plants OBL Plants that almost always (> 99% of the time) occur in wetlands, but which may rarely (< 1 % of the time) occur in non -wetlands.

Upland Plants UPL Plants that rarely (< 1 % of the time) occur in wetlands, and almost always (> 99% of the time) occur in non -wetlands. Source. Reed (1997) Project biologists used A Field Guide to the Common Wetland Plants of Western Washington and Northwest Oregon (Cooke 1997) and Plants of the Pacific Northwest (Pojar and MacKinnon 1994) as field references to assist with plant identification. Scientific and common plant names follow currently accepted nomenclature. Most names are consistent with Flora of the Pacific Northwest (Hitchcock and Springbrook Creek Mitigation Site Wetland Delineation Report WashkVton oSte tTransportatlon January 2005 A-1 Cronquist 1973) and the PLANTS Database (USDA 2001). During the field investigation, staff observed and recorded the dominant plant species on data sheets for each data plot (Appendix B). Soils Generally, an area must contain hydric soils to be a wetland. Hydric soil forms when soils are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part (12 inches). Biological activities in saturated soil result in reduced oxygen concentrations and organisms turn to anaerobic processes for metabolism. Over time, anaerobic biological processes result in certain soil color patterns, which are used as indicators of hydric soil. Typically, low-chroma colors are formed in the soil matrix, and bright -colored redoximorphic features form within the matrix. Other important hydric soil indicators include organic matter accumulations in the surface horizon, reduced sulfur odors, and organic matter staining in the subsurface (MRCS 2003). Project staff examined soils by excavating sample pits to a depth of 16 inches or more to observe soil profiles, colors, and textures. Munsell color charts (Greytag Macbeth 1994) were used to describe soil colors. Hydrology Project staff examined the area for evidence of hydrology. Wetland hydrology criteria were considered to be satisfied if it appeared that the soil was seasonally inundated or saturated to the surface for a consecutive number of days greater than or equal to 12.5 percent of the growing season. The growing season begins when the soil reaches a temperature of 41 degrees Fahrenheit in the zone of root penetration. The growing season in low elevations in western Washington is typically considered to be from March 1 to October 31 (244 days) (Washington State Department of Ecology, 1997). Primary indicators of hydrology include surface inundation and saturated soils. Secondary indicators of hydrology include drainage patterns, watermarks on vegetation, water -stained leaves, and oxidized root channels.
