Wetlands & Streams MemoResource & Environmental Planning 15020 Bear Creek Road Northeast • Woodinville, Washington 98077 • Bus: (425)861-7550 Fax: (425)861-7549 6 March 2020 TAL-1572C Dana Ostenson Federal Way Campus, LLC 11100 Santa Monica Boulevard, Suite 850 Los Angeles, California 90025 REFERENCE: Woodbridge Business Park Boundary Line Adjustment, Federal Way, Washington SUBJECT: Wetlands and Streams Existing Conditions Memo Dear Dana: This memo and attachments are provided in support of a boundary line adjustment (BLA) application to the City of Federal Way. This BLA covers areas around the existing Tech Center and adjacent lakefront property. The areas encompassed by this BLA include areas that have been previously reviewed by the City of Federal Way for the presence of wetlands and streams. The boundaries, ratings, and typings of these critical areas have been previously reviewed by ESA and the City of Federal Way. The reports that were previously provided to the City documenting these wetlands and streams are attached. Figure A shows the limits of the two (2) attached critical areas reports and shows how these report limits overlap the proposed BLA area. The two (2) attached tables reflect the most up to date information regarding wetland cover types, ratings, buffers at the time of the previous authorizations, and wetland sizes, as well as stream typings. Some wetlands included within the reports were removed as part of the previous review process, and so the immediately attached Tables 1 and 2 are to be considered the most accurate compilation of wetland and stream data for this site, broadly. All datasheets and rating sheets for the wetlands located within the limits of this BLA are attachments to these reports. There is some overlap between the two (2) reports. Important to note is that these reports and critical areas assessments were completed under the previous Federal Way Revised Code (FWRC) prior to the update of December 2019. The below table is provided to show how wetland buffers have changed between the December 2019 FWRC and the previous FWRC used in the attached reports. The biggest change is for wetlands within shoreline jurisdiction, which now use the Chapter 19 wetland buffer table, and for wetlands with a habitat score of 5, which are now included in the low habitat score for the purpose of applying a standard buffer width. 6 March 2020 Page 2 of 3 Resource & Environmental Planning 15020 Bear Creek Road Northeast • Woodinville, Washington 98077 • Bus: (425)861-7550 Fax: (425)861-7549 Table 1.

Woodinville, Washington 5 March 2020 Existing Conditions Report Woodbridge Business Park Federal Way, Washington Prepared For: Dana Ostenson Federal Way Campus, LLC 11100 Santa Monica Boulevard, Suite 850 Los Angeles, California 90025 Prepared By: Talasaea Consultants, Inc. 150250 Bear Creek Road NE Woodinville, Washington 98077 (425) 861-7550 5 March 2020 Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page i EXECUTIVE SUMMARY PROJECT NAME: Woodbridge Business Park PROJECT LOCATION: The approximate address for the Site is 32901 Weyerhaeuser Way South in the City of Federal Way, Washington. The project will take place on six parcels (King County Parcel numbers 1621049056, 1521049178, 1621049013, 1621049030, 2285000010, and 7978200420) totaling 146 acres. The Public Land Survey System location of the Site is Sections 16 and 21, Township 21 North, Range 4 East, Willamette Meridian. CLIENT: Tom Messmer, Vice President, Federal Way Campus, LLC PROJECT STAFF: Bill Shiels, Principal; Ann Olsen, RLA; Jennifer Marriott, PWS, Senior Ecologist; David Teesdale, PWS, Senior Ecologist; Richard Tveten, Senior Ecologist; Kristen Numata, Ecologist. FIELD SURVEY: Site evaluations and wetland delineations were performed over multiple days from December 2015 through April 2016. DETERMINATION: Sixty-three wetlands were identified on the Project Site. North Lake occurs adjacent to the Site. One man-made stream (Stream AC) connects the existing stormwater pond to Weyerhaeuser Pond off-site to the south. HYDROLOGY: Hydrology for the on-site wetlands is supported, for the most part, by seasonal precipitation and interception of surface water flow, as well as groundwater to a lesser extent. SOILS: The NRCS maps one type of soil over the majority of the Site, Alderwood gravelly sandy loam, 0 to 8 percent slopes. A small area in the northwest corner is mapped as Alderwood gravelly sandy loam, 8-15% slopes, and a small area of Orcas Peat is mapped over the far eastern portion of the Site. The National Technical Committee on Hydric Soils does not include Alderwood gravelly sandy loam as a hydric soil, however, Orcas Peat is identified as a hydric soil. VEGETATION: The Site is mix of developed areas and conifer and deciduous mixed forests. Typical native species present within the forested areas include Douglas fir, western red cedar, big-leaf maple, red alder, black cottonwood, salmonberry, vine maple, sword fern, and other native herbaceous and shrub species. Several non-native species of tree are present throughout the property, including several species of eastern oak and European ash. Typical vegetation within the wetlands includes salmonberry and hardhack with limited amounts of sedges and rushes.

The approximate address is 32901 Weyerhaeuser Way South in the City of Federal Way, Washington. The Site is approximately 146 acres in size. The remainder of the associated parcels under Federal Way Campus, LLC ownership are not a part of this project. The Public Land Survey System location of the Site is Sections 16 and 21, Township 21 North, Range 4 East, Willamette Meridian. The topography of the main portion of the Site, west of Weyerhaeuser Way S, is gently sloping downhill from the north to the south. The properties east of Weyerhaeuser Way South slope eastward to North Lake. The Site is bound to the east by North Lake, South 336th Street to the south, and Interstate 5 abuts the western edge of the Site. An office park is located north of the Site. The previous Weyerhaeuser headquarters building is located south of the Site across from Weyerhaeuser Pond. 2.2 Existing Site Development The Site is currently developed with the Weyerhaeuser Tech Center and associated infrastructure including six (6) parking lots, paved roads, gravel access roads and a private trail system that surrounds the building through the adjacent forested areas. A gas pipeline easement extends along the interstate frontage along the west edge of the property, and another gas pipeline extends from the office parcels north of the Site diagonally across the northeast corner of the Site. A stormwater pond is located southwest of the Tech Center and collects runoff from all of the roads and parking areas associated with the Tech Center. This pond discharges south into an artificial channel, now a naturalized stream, before ultimately discharging into Weyerhaeuser Pond. 2.3 Historical Land Uses The land at the north end of North Lake was historically developed as far back as the 1930s, based on accessible historical aerial photographs. The 1936 aerial photograph (www.historicaerials.org) reflects docks present all along the eastern shore of North Lake as well as around the northwest corner of the lake, along the existing shoreline within the Site. The 1964 aerial photograph (www.historicaerials.org) clearly shows a development of some kind that had multiple docks, buildings, and infrastructure. Evidence of wetland fill is noticeable between the 1936 and 1964 aerial photographs. This facility appears to have been abandoned around the time W eyerhaeuser purchased the property. The 1980 aerial photograph (www.historicaerials.com) seems to show the area being left to vegetate naturally. The previously apparent docks along this section of shoreline are no longer present in current aerial imagery. In addition to the old developments around North Lake, there is evidence of houses and residential areas along the old alignment of South 336th Street. These areas were Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 3 maintained through the 1960s, but appear to be overgrown by 1969, and by 1980 this area was completely redeveloped as part of the Weyerhaeuser Campus construction. CHAPTER 3. METHODOLOGY The critical areas analysis of the Site involved a two-part effort. The first part consisted of a preliminary assessment of the Site and the immediate surrounding area using published environmental information. This information includes: 1) Wetland and soils information from resource agencies; 2) Critical Areas information from King County and the City of Federal Way; 3) Orthophotography and LIDAR imagery; and, 4) Relevant studies completed or ongoing in the vicinity of the Site. The second part consisted of site investigations where direct observations and measurements of existing environmental conditions were made. Observations included plant communities, soils, hydrology, and stream conditions. This information was used to help characterize the site and define the limits of critical areas on-site and off-site for regulatory purposes (see Section 3.2 – Field Investigation below). 3.1 Background Data Reviewed Background information from the following sources was reviewed prior to field investigations: • US Fish and Wildlife Service (USFWS), Wetlands Online Mapper (National Wetlands Inventory, NWI) (USFWS, 2017) (www.wetlandsfws.er.usgs.gov/wtlnds/launch.html); • Natural Resources Conservation Service (NRCS), Web Soil Survey (NRCS, 2017)(www.websoilsurvey.nrcs.usda.gov/app/); • King County GIS Database (King County, 2017); • Orthophotography from USDA’s National Agricultural Imagery Program (NAIP 2017), Earth Explorer (USGS), and Google Earth. • Washington Department of Fish and Wildlife Priority Habitat and Species (PHS) Mapper; • USFWS listed species data; and • National Marine Fisheries Service (NMFS). 3.2 Field Investigation Talasaea Consultants originally evaluated the Site as part of a larger effort for Federal Way Campus, LLC beginning in December 2015. Talasaea re-verified the wetland boundaries in April 2016 once water levels returned to a normal state after the extremely high rains of December 2015. Brief site evaluations have been conducted since to verify that previously delineated boundaries are still appropriate. Wetland boundaries were evaluated by Ecological Science Associates (ESA) through the City of Federal Way between April and June 2017 as part of a boundary line adjustment request. Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 4 Our wetland delineation utilized the routine approach described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountain, Valleys, and Coast Regions (U.S. Army Corps of Engineers 2010). Plant species were identified according to the taxonomy of Hitchcock and Cronquist (Hitchcock, et al. 1969). Taxonomic names were updated and plant wetland status was assigned according to North American Digital Flora: National Wetland Plant List, Version 2.4.0 (Lichvar, et al. 2012). Wetland classes were determined with the U.S. Fish and Wildlife Service’s system of wetland classification (Cowardin, et al. 1979). Vegetation was considered hydrophytic if greater than 50% of the dominant plant species had a wetland indicator status of facultative or wetter (i.e., facultative, facultative wetland, or obligate wetland). Wetland hydrology was determined based on the presence of hydrologic indicators listed in the Corps’ Regional Supplement. These indicators are separated into Primary Indicators and Secondary Indicators. To confirm the presence of wetland hydrology, one Primary Indicator or two Secondary Indicators must be demonstrated. Indicators of wetland hydrology may include, but are not necessarily limited to: drainage patterns, drift lines, sediment deposition, watermarks, stream gauge data and flood predictions, historical records, visual observation of saturated soils, and visual observation of inundation. Soils on the site were considered hydric if one or more of the hydric soil indicators listed in the Corps Regional Supplement were present. Indicators include presence of organic soils, reduced, depleted, or gleyed soils, or redoximorphic features in association with reduced soils. An evaluation of patterns of vegetation, soil, and hydrology was made along the interface of wetland and upland. Wetland boundary points were then determined from this information and marked with wire flags or surveyors tape. Appendix A contains data forms prepared by Talasaea for representative locations in both upland and wetland locations. These data forms document the vegetation, soils, and hydrology information that aided in the wetland boundary determination. CHAPTER 4. RESULTS This section describes the results of our in-house research and field investigations. For the purpose of this report, the term “vicinity” describes an area within 105 feet of the Site. 4.1 Analysis of Existing Information The following sources provided information on site conditions based on data compiled from resource agencies and local government. 4.1.1 USGS Quadrangle The Project Site occurs on the Poverty Bay quadrangle. No features are mapped on the property, however, the quad map indicates North Lake and Weyerhaeuser Pond in Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 5 close proximity to the Site to the east and south, respectively. Wetlands are shown along the north shoreline of North Lake. No stream features are indicated on this map. 4.1.2 National Wetland Inventory The NWI maps a large wetland complex along the north shoreline of North Lake and a palustrine scrub-shrub/emergent, persistent, seasonally flooded wetland (PSS/EM1C) to the northwest of the Site (Figure 2). The large wetland complex is classified as a palustrine scrub-shrub/emergent, persistent, seasonally flooded (PSS/EMC) wetland adjacent to a palustrine emergent (persistent)/palustrine scrub-shrub, semi-permanently flooded (PEM1/SSF) wetland. One stream is mapped along the southern edge of the property flowing westbound, though this feature is not present in the field. No NWI wetlands are mapped within the Site. 4.1.3 Natural Resources Conservation Service The NRCS maps one type of soil over the majority of the Site, Alderwood gravelly sandy loam, 0 to 8 percent slopes (Figure 3). Alderwood gravelly sandy loam, 8-15% slopes is mapped over a small area in the northwest corner of the Site, while Orcas Peat is mapped over the far eastern portion of the Site near an existing wetland that is adjacent to North Lake. The National Technical Committee on Hydric Soils does not include Alderwood gravelly sandy loam as a hydric soil, though Orcas Peat is identified as a hydric soil. 4.1.4 King County GIS Database King County does not map any critical areas on the Site, but both North Lake and Weyerhaeuser Pond are mapped as wetland units. One 2S stream is indicated as connecting North Lake and Weyerhaeuser Pond off-site. 4.2 Analysis of Existing Conditions – Wetlands The Site west of Weyerhaeuser Way South is currently developed with the former Weyerhaeuser Tech Center and associated infrastructure including parking and stormwater facilities. The buildings and infrastructure were constructed in 1978. Roughly half of the Site contains conifer/deciduous mixed forests, though the forested areas are separated by the roads, trails, and broadly-spaced parking configuration. The stormwater pond on-site collects runoff from much of the existing development, and conveys the treated water downstream through a man-made channel. The channel (identified as Stream AC) flows southward to its confluence with a perennial stream that connects North Lake to the Weyerhaeuser Pond (Figure 4). North Lake abuts the eastern edge of the Site, and is a Shoreline of the State. The areas on the east side of Weyerhaeuser Way South are separated by an access road to a public boat ramp managed by WDFW. North of this boat ramp road are the northern limits of a large wetland complex that extends to North Lake, surrounded by a coniferous forest. A sewer line easement crosses this area and was replanted some time ago. South of the boat ramp road are portions of several wetlands that appear to collect extra runoff from the roadside ditches associated with the boat ramp road through the winter months. Most of these wetlands are not directly associated with Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 6 North Lake. The sewer line easement continues across this portion of the property as well. Much of the Site is underlain by glacial till. This dense material frequently possesses inclusions consistent with redoximorphic features except they lack the diffuse boundaries characteristic of active wetland hydrology. This material is also very difficult to dig through for complete soil profiling. In addition, a number of non-native species of trees occur along the existing gravel roads, having been planted over the years. A large area immediately west and southwest of the Tech Center, identified on older maps as an “experimental tree farm,” was completely cleared of the native conifers sometime between 1980 and 1990, and replanted primarily with European ash (Fraxinus excelsior) trees. This area has since regrown with the European ash being dominant is some areas, and the remainder dominated by a combination of black cottonwood and red alder with scattered Western red cedar. These areas coincide with the location of many of the delineated wetlands, which are small depressions in the landscape that are likely residual from the clearcutting effort of the 1980s. Talasaea Consultants performed an initial delineation of on-site wetlands beginning in December 2015. Talasaea re-verified the wetland boundaries in April 2016 as the initial delineations were completed after several atypically high rainfall events. Sixty-three wetlands were identified on the Project Site (Appendix E, Sheets W1.0-W1.2). North Lake occurs adjacent to the Site. One man-made stream (Stream AC) connects the existing stormwater pond to Weyerhaeuser Pond off-site to the south. Several ditch- outs and old log skid trails occur through the western woods on-site that hold water during the winter but neither convey water nor meet the wetland definition. The wetland labels are non-sequential as the wetlands were delineated as part of a larger effort. A complete table outlining the wetland classification, size, and other information of all the wetlands can be found in Appendix B. General descriptions can be found below. Photographs of typical conditions within the wetlands, including typical uplands and access roads, are included within Appendix C. Wetlands outside of the Shoreline Management Zone (SMZ) have been rated using the Washington State Wetland Rating System for Western Washington (Ecology Publication # 14-06-029) (Appendix D). Wetlands occurring within the SMZ along North Lake were rated using the rating system outlined in the Federal Way Revised Code (FWRC) Chapter 15.10 Critical Areas. 4.2.1 Wetlands AE, AF and AH Wetlands AE, AF, and AH are small, depressional palustrine emergent wetlands located south of the stormwater pond. Hydrology is provided seasonally by the stormwater pond through surface water and groundwater leakage from the pond, which collects runoff from the entire Weyerhaeuser Tech Center. Typical vegetation includes sedges and rushes, such as soft rush and slough sedge. 4.2.2 Wetland AG Wetland AG is a palustrine forested/scrub-shrub wetland located around the stormwater pond. This wetland occurs at the toe of the slope of the berm surrounding the stormwater pond, and it is likely that hydrology comes from groundwater seeping Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 7 through the berm as well as surface water from the vicinity. This wetland extends south along either side of Stream AC, the artificial discharge of the stormwater pond. Typical vegetation is red alder, black cottonwood, and salmonberry. 4.2.3 Wetlands AI, AL, AJ, AO, AR, AS, AM These wetlands are a series of small slope and depressional wetlands that occur north of South 336th Street. These herbaceous wetlands are dominated by pasture grasses, typically a mix of rye (Lolium spp.), fescues (Festuca spp.), bentgrasses (Agrostis spp.), velvet grass (Holcus lanatus), sweet vernal grass (Anthoxanthum odoratum), and others. 4.2.4 Wetland AV Wetland AV is a medium sized wetland-upland mosaic located to the west of the Tech Center. Wetland AV is classified as a palustrine forested wetland. Typical species include red alder, salmonberry and creeping buttercup. This is part of an area that was planted with European ash, located in clear rows. This general area has poor drainage due to disturbance over the past few decades that has resulted in ponded water within small depressional pockets through these woods. Many of these pocket wetlands were delineated based on the presence of hydrology and hydric soils as the vegetation across a broad area is facultative. 4.2.5 Wetland BA Wetland BA is a relatively small depressional, forested wetland located adjacent to the boat ramp road. This wetland is partially located within the SMZ. This wetland receives run-off from the boat ramp road, and has a culvert that connects this to the Wetland CD complex on the east side of the boat ramp road. Typical vegetation includes red alder and salmonberry. This wetland is also topographically connected to Wetlands BA-2 and PK at high water levels common through the winter months, though this connection is generally not apparent outside of the winter rainy season. 4.2.6 Wetland BA-2 This small, depressional, shrubby wetland is dominated by salmonberry and other small wetland shrubs. This wetland was formerly part of a larger delineation for Wetland BA, however, after a thorough analysis of this larger area, it was determined that Wetlands BA and BA-2 represented the true wetland components that reflected all 3 parameters of a wetland. The other, discarded areas lacked hydric soils and/or sufficient, long-term hydrology that met the parameters to be considered wetlands. This wetland occurs outside of the SMZ. 4.2.7 Wetland BB This small, depressional, forested wetland is located adjacent to the boat ramp road, and falls within the SMZ. This wetland receives road run-off from the boat ramp road and drains south to Wetland BD North. 4.2.8 Wetland BD-North Wetland BD-North is a large lakeshore wetland associated with North Lake that occurs within the SMZ. The entirety of this wetland extends off-site to the north and to the Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 8 south. This wetland is mostly forested and is dominated by red alder and salmonberry. Hydrology for Wetland BD-North is supported by the lake, surrounding uplands, and Weyerhaeuser Way South. During the winter site visits, water was observed sheet flowing across the gravel path upslope near Wetlands BE and BF before entering Wetland BD-North. Hydrology for these smaller wetlands appears driven by road run- off from Weyerhaeuser Way South. 4.2.9 Wetland BE Wetland BE is a small slope wetland located on the upslope side of a gravel road that separates Wetland BE from the lakeshore Wetland BD North. This wetland occurs within the SMZ. The dominant vegetation is salmonberry. Hydrology is generally provided by precipitation and shallow groundwater, and this wetland receives run-off from Weyerhaeuser Way South. 4.2.10 Wetland BF Wetland BF is a slope wetland located on the upslope side of a gravel road that separates Wetland BF from the lakeshore Wetland BD North. This wetland occurs within the SMZ. Dominant vegetation is red alder and salmonberry. Hydrology is generally provided by precipitation and shallow groundwater, and this wetland receives run-off from Weyerhaeuser Way South. 4.2.11 Wetland BK Wetland BK is a small palustrine scrub-shrub sloped wetland located between Weyerhaeuser Way South and North Lake. This wetland occurs within the SMZ. Vegetation is dominated by salmonberry. Hydrology is generally provided by precipitation and shallow groundwater, and this wetland receives run-off from Weyerhaeuser Way South. 4.2.12 Wetland BL Wetland BL is a medium palustrine scrub-shrub slope wetland located between Weyerhaeuser Way South and North Lake. This wetland occurs within the SMZ. Vegetation is dominated by salmonberry. Hydrology is supported by precipitation and shallow groundwater, and this wetland receives run-off from Weyerhaeuser Way South. 4.2.13 Wetland BR Wetland BR is a pocket of wetland located west of the stormwater pond. This wetland occurs at the edge of the forested area, immediately east of a gravel road that is used to access this portion of the Site. This wetland is a collection of small depressional pockets that contain soft rush and various sedges, with small areas of salmonberry and red elderberry. Western red cedar and red alder also occur within the wetland. Hydrology is generally provided through the interception of shallow ground water and precipitation. Some overland flow is likely provided from Wetland AG with higher rainfall or higher discharges from the stormwater pond. 4.2.14 Wetland BS-North Wetland BS-North is a palustrine forested wetland located in a depression between two parking lots north of the Tech Center. Vegetation within the wetland is dominated by Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 9 salmonberry, tall manna grass, and soft rush with quaking aspen and red alder present as well. Hydrology for BS-North is supported by parking lot runoff and precipitation. 4.2.15 Wetland BS-South Wetland BS-South is a palustrine emergent wetland located off-site adjacent to Wetland BR. Vegetation is dominated by various grass species with hydrology supported by surface water flows and precipitation. 4.2.16 Wetland CB Wetland CB is a palustrine forested wetland located east of Weyerhaeuser Way South and north of the boat ramp road. Vegetation is dominated by red alder and Oregon ash. Hydrology is supported by precipitation, stormwater discharge from the office park stormwater pond off-site on the west side of Weyerhaeuser Way South, and a non- regulated swale that receives runoff from Weyerhaeuser Way South. 4.2.17 Wetland CD Wetland CD is a palustrine forested and scrub-shrub wetland located partially on-site east of Weyerhaeuser Way South north of the boat ramp road. The majority of this wetland occurs off-site along the east side of the boat ramp, and connects directly to North Lake. Vegetation is dominated by willows, red alder, and salmonberry. The off- site components of this wetland were not evaluated. Hydrology is supported by North Lake, overland flow from the surrounding areas, and precipitation. 4.2.18 Wetland CE This very small depression is located next to Weyerhaeuser Way South and was questionably considered wetland. However, due to an abundance of caution, this area was identified despite its likely presence as a result of a tree falling. 4.2.19 Wetland CG Wetland CG is located on the east side of Weyerhaeuser Way South and is a depressional pocket within the surrounding coniferous forest. This wetland connects to Wetlands BA, BA-2 and PK during periods of high water in the rainy season, though no long-term hydrologic connection is apparent between these wetlands. Wetland CG appears to be a remnant of past logging activities. No vegetation is dominant within this wetland as overall vegetative coverage is less than 20% total and is restricted to small shrubs on hummocks. A dense canopy cover is present due to the adjacent western red cedars, most of which occur outside of the wetland boundaries. 4.2.20 Wetland DE Wetland DE is a large palustrine forested wetland located west of the Tech Center. Vegetation within the wetland is dominated by European ash, soft rush, a variety of sedges and facultative grasses. Hydrology for Wetland DE is provided by precipitation and interception of surface flows. This is part of an area that was planted as part of the Weyerhaeuser Campus experimental tree farm with European ash, located in clear rows. This general area has poor drainage due to disturbance over the past few decades that has resulted in ponded water within small depressional pockets through Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 10 these woods. Consolidated till generally occurs near the soil surface which precludes the downward movement of water. 4.2.21 Wetlands DF, DG, DH, and DI Wetlands DF, DG, DH, and DI are a series of wetlands located within the woods between Wetland DE and the Tech Center. These wetlands are classified as palustrine forested, and are dominated by black cottonwood, European ash, Douglas spirea, salmonberry, and Dewey’s sedge. Hydrology for these wetlands is provided by precipitation and interception of surface flows. This is part of an area that was planted as part of the former Weyerhaeuser Campus experimental tree farm with European ash, located in clear rows. This general area has poor drainage due to disturbance over the past few decades that has resulted in ponded water within small depressional pockets through these woods. Consolidated till near the soil surface severely restricts the downward movement of water. 4.2.22 Wetland DK Wetland DK is a palustrine scrub-shrub wetland located west of the Tech Center. This wetland is generally dominated by small patches of wetland grasses, sedges, and rushes with trees occurring within proximity to the wetland, but not within the wetland. Hydrology for this wetland is provided by precipitation and interception of surface flows. This is part of an area that was planted as part of the former Weyerhaeuser Campus experimental tree farm with European ash, located in clear rows. This general area has poor drainage due to disturbance over the past few decades that has resulted in ponded water within small depressional pockets through these woods. Consolidated till near the soil surface severely restricts the downward movement of water. 4.2.23 Wetland EI Wetland EI is a small palustrine forested wetland located northwest of the Tech Center. Vegetation within the wetland is dominated by salmonberry and ruffled starwort. Soils were hydric, and hydrology for this wetland is provided by precipitation and interception of surface flows. 4.2.24 Wetlands EJ, EK, EL, and EM Wetlands EJ, EK, EL, and EM are a cluster of wetlands located northwest of the Tech Center. These wetlands are located within an area dominated by deciduous tree species, the conifers have been logged out years ago. These wetlands are classified as palustrine scrub-shrub and are dominated by salmonberry. Hydrology for Wetlands EJ, EK, EL and EM is provided by precipitation and interception of surface flows. The wetland boundaries were delineated based on the presence of wetland hydrology and hydric soils since many species in the area were facultative wetland species. 4.2.25 Wetland FA Wetland FA is a palustrine scrub-shrub wetland located along the northern property line. The majority of this wetland occurs off-site to the north. Vegetation within the wetland is dominated by red alder and salmonberry. Hydrology for FA is provided through precipitation and interception of surface flows. Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 11 4.2.26 Wetland FB Wetland FB is a palustrine scrub-shrub wetland located along the northern property line in the northeast corner of the property. Vegetation within the wetland is dominated by young Oregon ash and salmonberry. Hydrology for FB is provided through precipitation and interception of surface flows. 4.2.27 Wetland FD Wetland FD is a palustrine forested wetland located north of the Tech Center that abuts a pipeline right-of-way. This wetland resulted from the impoundment of water behind a berm created through the installation of a pipeline across this area. Hydrology for FD is provided through precipitation and interception of surface flows. 4.2.28 Wetland FE Wetland FE is a palustrine forested wetland located north of the Tech Center by the outdoor volleyball court, adjacent to a gravel road. Portions of this wetland appear to have been artificially excavated, and given the location of this feature near the highest point across the Site, this wetland formed through the impoundment of water because the gravel road acts as a berm. Vegetation within the wetland includes red alder, salmonberry, and creeping buttercup. Hydrology for FE is provided through precipitation and interception of surface flows. 4.2.29 Wetland FF Wetland FF is a palustrine scrub-shrub wetland located north of the Tech Center. This wetland resulted from the impoundment of water behind a berm created through the installation of a pipeline across this area. Vegetation within the wetland is dominated by red alder, salmonberry, and lady fern. Hydrology for FF is provided through precipitation and interception of surface flows. 4.2.30 Wetland GB-North Wetland GB-North is a palustrine scrub-shrub wetland located west of the Tech Center. Vegetation within the wetland is dominated by red-osier dogwood and reed canarygrass. Hydrology for GB-North is provided through precipitation and interception of surface flows. 4.2.31 Wetland IA Wetland IA is a slope wetland located in the southwest corner of the Site. This wetland intercepts surface water and shallow subsurface flows from the adjacent hillslopes and conveys the water to a culvert under South 336th Street. This water ultimately flows into Weyerhaeuser Pond. The wetland is dominated by a variety of grasses and sedges. Saturated soil conditions were observed throughout winter and early spring with hydric soil indicators present. 4.2.32 Wetlands KA, KB, KC, KD, KF, KG, KH, KI, KJ, KK, KL, KM, KN, KT, KU, KV, KW These wetlands are a series of small slope and depressional wetlands that occur north of South 336th Street. These herbaceous wetlands are dominated by pasture grasses, typically a mix of rye (Lolium spp.), fescues (Festuca spp.), bentgrasses (Agrostis spp.), Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 12 velvet grass (Holcus lanatus), sweet vernal grass (Anthoxanthum odoratum), and others. 4.2.33 Wetland PG (Previously identified as Wetland BJ) Wetland PG is a large wetland located in the southeastern corner of the site between Weyerhaeuser Way S and North Lake. This wetland is classified as both a palustrine forested and scrub-shrub sloped wetland. The delineation for Wetland PG shrunk after spring evaluations of the area during more normal rainfall patterns. Wetland PG is dominated by red alder and salmonberry. 4.2.34 Wetland PK Wetland PK is part of the former larger delineation of Wetland BA, and is a small forested wetland within a more recently disturbed area. This wetland occurs within an area that lacks the conifer canopy common through much of this portion of the Site. The areas within and around Wetland PK are dominated by red alder and other deciduous trees that are generally younger than the surrounding conifers. 4.3 Analysis of Existing Conditions – Streams and Other Features No natural streams occur within the Site, though a stream connecting North Lake to Weyerhaeuser Pond occurs off-site to the south. A number of man-made depressional features occur across the landscape that neither convey water nor meet the definition of a wetland. These features appear to be remnants from when this forest was logged in the 1980s shortly after the construction of the Tech Center. Some of the features were likely dug for surface water management to ensure the gravel paths through the woods remained free from ponded water. These features rarely connect to wetlands, but where they did, they were delineated as part of the wetland where appropriate. Many of the ditches and swales connect to the on-site stormwater facility in some fashion, either through direct surface connections or via the pipes that drain the roads and parking areas to the on-site stormwater pond. This stormwater pond then discharges through a man-made conveyance (Stream AC) that ultimately flows into Weyerhaeuser Pond through a connection to a natural stream. The combined streams flow f or approximately 600 feet before entering the Weyerhaeuser Pond. The Weyerhaeuser Pond then discharges south through a control structure into a buried pipe that is located underneath the former Weyerhaeuser Headquarters Building. The flows from this stormwater pond and associated channel ultimately enter the Hylebos Creek several miles south of the Site (Figure 4). 4.3.1 North Lake North Lake is a Shoreline of the State and is located adjacent to the northeast parcels within the Property. This 50-acre lake is periodically stocked with rainbow trout by WDFW, and has a resident largemouth bass population that is maintained for fishing. While no motorized boats are allowed on this lake, there is a dock at the north end at the WDFW maintained access point. 4.3.2 Weyerhaeuser Pond (off-site) Weyerhaeuser Pond was constructed in conjunction with the former Weyerhaeuser Headquarters building. Weyerhaeuser Pond is located off-site to the south, but is the Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 13 receiving body for some of the Site stormwater. This pond serves both as a stormwater pond and natural feature that attracts waterfowl and other wildlife. Weyerhaeuser pond does collect runoff from the surrounding areas, as well as from the North Lake. This man-made pond is not a Shoreline of the State. A control structure at the south end of the pond limits the flows out of this pond. A pipe conveys flows out of the pond, underneath the Headquarters building, through the meadow immediately south of the building, before discharging at a headwall located south of the Weyerhaeuser Road, north of Highway 18. 4.3.3 Stream AC A stormwater pond for the Tech Center, located north of the Headquarters building, collects runoff from approximately 2/3 of the Tech Center and surrounding areas. This stormwater pond conveys the treated water downstream through a man-made channel (Stream AC) that extends into the Property before flowing south under South 336th Street to its confluence with Stream HA. The combined streams flow for approximately 600 feet before entering Weyerhaeuser Pond. Weyerhaeuser Pond then discharges south through a structure into a buried pipe that is located underneath the Headquarters building. The flows from this series of streams ultimately enter the Hylebos Creek some two (2) miles south of the Property. This conveyance feature, identified as Stream AC for the purposes of this report, has not been maintained over the years and has become more naturalized, despite the primary source of flow being the stormwater pond discharge. Stream AC starts at the stormwater pond outlet, but also collects water from the adjacent wetlands. The flow regime of this stream is directly tied to the discharges from the stormwater pond. While this feature was artificially created, its connection to fish-bearing waters and naturalization over time ensures that this feature has at least the potential to sustain fish habitat. 4.3.4 Non-regulated Ditches Several ditches and swales have been constructed and are actively maintained across the Property that tie into natural features. A pair of swales (AT1 and AT2) convey water from the sewer line easement north of South 336th Street south to a culvert under South 336th Street, before discharging these waters into Weyerhaeuser Pond. CHAPTER 5. WILDLIFE AND LISTED SPECIES 5.1 Wildlife Surveys and Assessments The Site was evaluated for wildlife habitat and observations of wildlife were recorded during all field visits since December 2015. The general habitat on-site is a blend of small depressional wetlands, 3rd growth Douglas fir forest with a patchy salal/sword fern understory, and a mixed deciduous forest with a primarily salmonberry understory. An existing stormwater pond occurs adjacent to several wetlands near the west side of the Site, and a naturalized stream originating from the stormwater pond discharge also occurs on-site. North Lake occurs adjacent to the eastern most portion of the project area. No unique habitats occur on-site. Both North Lake and Stream AC have potential habitat for salmonids and other freshwater fish. Both features provide fish habitat at a minimum. Though no fish of any species were observed within Stream AC, North Lake Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 14 is regularly stocked with rainbow trout, and presumably has many other fish species present. Listed species evaluated for effects include the listed salmonids (Chinook salmon, steelhead, bull trout) to address the potential for downstream water quality impacts. General wildlife observations during field work include: American Robin, Pacific Wren, Canada Goose, Chickadee, Ruby-crowned Kinglet, Red-winged Blackbird, Pileated Woodpecker, Bufflehead, Mallard, American Widgeon, American Crow, American Coot, Pied-billed Grebe, Rufous Hummingbird, mountain beaver (burrows), rabbit, deer, coyote, and bullfrogs. 5.2 Listed Species There are no known listed species occurring on or adjacent to the Site. Listed species (salmonids) do occur downstream in Hylebos Creek, and a bald eagle nest is located more than 1,000 feet SE of North Lake. W hile bald eagles likely use North Lake for foraging, no direct impacts are proposed to North Lake. Any stormwater discharges would be treated prior to being discharged into North Lake or into downstream waterbodies. North Lake is stocked with rainbow trout. Weyerhaeuser Pond off-site to the south of the Site may also be used by bald eagles for foraging, but this pond has previously been recognized as a large stormwater facility that acts as detention and treatment. Salmonids have not been observed in any of the streams, lake or pond within the greater Federal Way Campus, LLC property. The apparent hindrances restricting salmonid migration into this area appear to be several not-fish-accessible culverts downstream. There is also a long stretch of pipe (roughly 1,600 linear feet) from the Weyerhaeuser pond, under the former Weyerhaeuser headquarters building, to its outlet just north of Highway 18, that is likely problematic for fish passage. The potential for federally or state listed species occurring within the Site is very low. North Lake and the associated streams have the capacity for salmonids to occur, though accessibility from Hylebos Creek is artificially restricted. North Lake is stocked with rainbow trout, at a minimum. While no salmon species have been observed within North Lake or associated streams that does not preclude the potential for their presence. No impacts within the ordinary high water mark for any stream or lake is proposed as part of this project, though maintenance of an existing stormwater structure will be necessary. All stormwater will be treated prior to discharge and conveyance into a fish-bearing water. CHAPTER 6. REGULATORY REVIEW 6.1 Federal and State Regulations Wetland impacts on the project site are subject to applicable State and Federal regulations. Wetland impacts are regulated on the Federal level by Sections 404 and 401 of the Clean Water Act. The US Army Corps of Engineers is responsible for administering compliance with Section 404 via the issuance of Nationwide or Individual Permits for any fill or dredging activities within wetlands. Any project that is subject to Section 404 permitting is also subject to requirements of Section 401 of the Clean Water Act (CWA), administered by the Department of Ecology (DOE). Because direct Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 15 wetland impacts are proposed on the project site, the project would be required to comply with all Section 404 and 401 permitting requirements prior to any construction- related activities that would affect “waters of the US.” The project is being evaluated by the Corps for a Nationwide Permit 39. 6.2 City of Federal Way Zoning Code Wetlands and other critical areas in Federal Way, including those located within the Shoreline Management Zone (SMZ), are regulated under the Federal Way Revised Code (FWRC) Chapter 19.145. 6.2.1 Non-SMZ Wetlands Wetlands occurring outside of the SMZ in Federal Way are currently regulated under FWRC 19.145.420. Wetlands regulated under Chapter 19 of the FWRC should be rated using the Washington State Wetlands Rating System for Western Washington (2014). The ratings for wetlands determine the appropriate buffer width requirements as specified in the Federal Way Revised Code. Wetland ratings and rating figures can be found in Appendix D. Wetlands identified within the Site, but outside of the SMZ, typically rated as a Category III or IV with Habitat Scores ranging from three (3) to six (6). Wetland setbacks in the FWRC are determined first by Category and then by Habitat Score (Table 1). See Appendix B for wetland ratings, categories, and standard buffer for all critical areas. Table 1. FWRC Wetland Buffer Requirements (FWRC 19.145.420) Wetland Category Wetland Buffer Width (based on Habitat Score) 3-4 5 6-7 8-9 Category I: Bogs and wetlands of high conservation value 190 feet 190 feet 190 feet 225 feet Category I: Forested and based on function score 75 feet 105 feet 165 feet 225 feet Category II 75 feet 105 feet 165 feet 225 feet Category III 60 feet 105 feet 165 feet 225 feet Category IV 40 feet 40 feet 40 feet 40 feet 6.2.2 Streams Stream AC is classified as a fish-bearing Type F stream. Type F streams under FWRC Chapter 19.145.270 require a 100-foot standard buffer. No other streams occur within the Site that would require buffers. 6.3 Shoreline Management Zone (SMZ) North Lake is listed as a Shoreline of the State, and thus is located within the SMZ for the Department of Ecology and the City of Federal Way. Shorelands extend for 200 feet from the ordinary high water mark (OHWM) for North Lake and include Wetlands Woodbridge Business Park Existing Condition Report 5 March 2020 Copyright © 2020 Talasaea Consultants, Inc. 1572C Existing Conditions Report Page 16 BA, BB, BD-North, BE, BF, BK, BL and CD. In addition to a 50-foot lakeshore buffer, these areas along the shoreline of North Lake have extra protections under the SMZ, which require additional coordination for any modifications within this area. 6.4 Other Linear Features All other man-made depressional features would not require buffers as they are all non- jurisdictional features. CHAPTER 7. SUMMARY The Woodbridge Business Park Site is an approximately 146-acre assemblage of portions of six parcels located within the City of Federal Way in King County, Washington. The (former) Weyerhaeuser Tech Center already occurs within the Site with associated parking, paved roads, existing gravel access roads, and trails for passive recreation are present on-site. Talasaea Consultants performed an initial delineation of on-site wetlands beginning in December 2015. Talasaea re-verified the wetland boundaries in April 2016 as the initial delineations were completed after several atypically high rainfall events. Sixty-three wetlands were identified on the Project Site. North Lake occurs adjacent to the Site. One man-made stream (Stream AC) connects the existing stormwater pond to Weyerhaeuser Pond off-site to the south. Wetlands and other critical areas in Federal Way, including those located within the Shoreline Management Zone (SMZ), are regulated under the Federal Way Revised Code (FWRC) Chapter 19.145.

The Property is comprised of five (5) parcels. The Public Land Survey System location of the Property is Sections 15 and 16, Township 21 North, Range 4 East, Willamette Meridian. PROJECT STAFF: Bill Shiels, Principal; Jennifer Marriott, PWS, Senior Ecologist; David Teesdale, PWS, Senior Wetland Ecologist; Richard Tveten, Senior Ecologist; and Kristen Numata, Ecologist. FIELD SURVEY: Property evaluations and wetland delineations were performed on multiple days from December 2015 through August 2017. DETERMINATION: Forty-nine (49) wetlands were identified on the Property, with an additional three (3) wetlands located adjacent to the Property within 100 feet. Sections of one (1) stream (fish-bearing) and three (3) swales are located on the Property. North Lake occurs adjacent to the eastern parcels of the Property. Weyerhaeuser Pond is located approximately 300 feet south of the Property. HYDROLOGY: Hydrology for the on-site wetlands is supported by seasonal precipitation and interception of surface water flow, as well as groundwater movement to a lesser extent. SOILS: The NRCS maps two soil map units over the Property: Alderwood gravelly sandy loam, 0 to 8 percent slopes over the majority and Orcas Peat in a small portion along the eastern property boundary. The National Technical Committee on Hydric Soils does not include Alderwood gravelly sandy loam as a hydric soil, however, Orcas Peat is identified as a hydric soil. VEGETATION: The Property is mix of developed and managed areas with conifer and deciduous mixed forests. Typical native species present within the forested areas include Douglas fir, western red cedar, big-leaf maple, red alder, black cottonwood, salmonberry, vine maple, sword fern, and other native herbaceous and shrub species. Several non-native species of tree are present throughout the property, including several species of eastern oak and European ash. Typical vegetation within the wetlands includes salmonberry and hardhack with limited amounts of sedges and rushes. English ivy is present across the Property in varying densities.

PROPERTY DESCRIPTION 2.1 Property Location The Property is comprised of five (5) parcels currently owned by Federal Way Campus, LLC (FWC, LLC) identified internally as Parcels F, J, L, BLA 2-3, and BLA 3-1 (Figure 2). A complete list of King County Parcel numbers, and their letter association, is provided on Figure 2. Boundary line adjustment (BLA) parcel boundaries have been recently approved by the City of Federal Way (Attachment A and B), therefore there are no King County Parcel numbers yet assigned. The Property address is 32820 32nd Avenue South in the City of Federal Way, Washington for the northeast most parcel. The Property is approximately 74 acres in size. The remainder of the associated parcels under FWC, LLC ownership are not a part of this project. The Public Land Survey System location of the Property is Sections 15 and Section 16, Township 21 North, Range 4 East, Willamette Meridian. The topography of the Property west of Weyerhaeuser Way South, is gently sloping downhill from the north to the south. The properties east of Weyerhaeuser Way South slope east to North Lake. The Property is bound to the east by North Lake, to the south by South 336th Street, and Interstate 5 abuts the western edge of the Property. Other property owned by the Applicant occurs north of the Property that is partially developed as a technology center with large areas of open parking. The former Weyerhaeuser headquarters building (now known as the Greenline Headquarters Building) is located south of the Property across from Weyerhaeuser Pond. 2.2 Existing Property Development The Property is currently developed with a portion of the stormwater facility associated with the Weyerhaeuser Tech Center and associated infrastructure, as well as portions of gravel access roads and a private trail system that meanders throughout the remainder of the Property. The stormwater pond is located southwest of the Tech Center within the Property and collects runoff from all of the roads and parking areas associated with the Tech Center. This pond discharges south into an artificial channel, now a naturalized stream, before ultimately discharging into Weyerhaeuser Pond. A gas pipeline easement extends along the interstate frontage along the west edge of the property. A vacated single family residence is located on the lakeshore properties east of Weyerhaeuser Way S near the northwest corner of the lake.

The 1936 aerial photograph reflects docks present all along the eastern shore of North Lake as well as around the northwest corner of the lake, along the existing shoreline within the Property. The 1964 aerial photograph clearly shows a development of some kind that had multiple docks, buildings, and infrastructure. Evidence of wetland fill is noticeable between the 1936 and 1964 aerial photographs. This facility appears to have been abandoned around the time Weyerhaeuser purchased the property. The 1980 aerial photograph seems to show the area being left to vegetate naturally. The previously apparent docks along this section of shoreline are no longer present in current aerial imagery. In addition to the old developments around North Lake, there is evidence of houses and residential areas along the old alignment of South 336th Street. These areas were maintained through the 1960s, but appear to be overgrown by 1969, and by 1980 this area was completely redeveloped as part of the Weyerhaeuser Campus construction. CHAPTER 3. METHODOLOGY The critical areas analysis of the Property involved a two-part effort. The first part consisted of a preliminary assessment of the Property and the immediate surrounding area using published environmental information. This information includes: 1) Wetland and soils information from resource agencies; 2) Critical Areas information from King County and the City of Federal Way; 3) Orthophotography and LIDAR imagery; and, 4) Relevant studies completed or ongoing in the vicinity of the Property. The second part consisted of Property investigations where direct observations and measurements of existing environmental conditions were made. Observations included plant communities, soils, hydrology, and stream conditions. This information was used to help characterize the Property and define the limits of critical areas on-site and off- site for regulatory purposes (see Section 3.2 – Field Investigation below). 3.1 Background Data Reviewed Background information from the following sources was reviewed prior to field investigations: • US Fish and Wildlife Service (USFWS), Wetlands Online Mapper (National Wetlands Inventory) (USFWS, 2018) (www.wetlandsfws.er.usgs.gov/wtlnds/launch.html); • Natural Resources Conservation Service (NRCS), Web Soil Survey (NRCS, 2018) (www.websoilsurvey.nrcs.usda.gov/app/); • King County GIS Database (King County iMap, 2018); • Orthophotography from USDA’s National Agricultural Imagery Program (NAIP 2018), Earth Explorer (USGS), and Google Earth; Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 4 • Washington Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) Mapper; • Salmonscape (WDFW) (http://wdfw.wa.gov/mapping/salmonscape); • StreamNet (The Pacific States Marine Fisheries Commission) (http://www.streamnet.org/data/interactive-maps-and-gis-data/) • USFWS listed species data; and • National Marine Fisheries Service (NMFS). 3.2 Field Investigation Talasaea Consultants originally evaluated the Property as part of a larger effort for Federal Way Campus, LLC beginning in December 2015. Talasaea re-verified the wetland boundaries in April 2016 once water levels returned to a normal state after the extremely high rains of December 2015. Brief site evaluations have been conducted since to verify that previously delineated boundaries are still appropriate. Wetland boundaries were evaluated by Ecological Science Associates (ESA) through the City of Federal Way between April and June 2017 as part of two (2) previous boundary line adjustment requests. Approval of these previous two (2) BLA applications was granted in October 2017. Our wetland delineation utilized the routine approach described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountain, Valleys, and Coast Regions (U.S. Army Corps of Engineers 2010). Plant species were identified according to the taxonomy of Hitchcock and Cronquist (Hitchcock, et al. 1969). Taxonomic names were updated and plant wetland status was assigned according to North American Digital Flora: National Wetland Plant List, Version 2.4.0 (Lichvar, et al. 2012). Wetland classes were determined with the U.S. Fish and Wildlife Service’s system of wetland classification (Cowardin, et al. 1979). Vegetation was considered hydrophytic if greater than 50% of the dominant plant species had a wetland indicator status of facultative or wetter (i.e., facultative, facultative wetland, or obligate wetland). Wetland hydrology was determined based on the presence of hydrologic indicators listed in the Corps’ Regional Supplement. These indicators are separated into Primary Indicators and Secondary Indicators. To confirm the presence of wetland hydrology, one Primary Indicator or two Secondary Indicators must be demonstrated. Indicators of wetland hydrology may include, but are not necessarily limited to: drainage patterns, drift lines, sediment deposition, watermarks, stream gauge data and flood predictions, historical records, visual observation of saturated soils, and visual observation of inundation. Soils on the Property were considered hydric if one or more of the hydric soil indicators listed in the Corps Regional Supplement were present. Indicators include presence of organic soils, reduced, depleted, or gleyed soils, or redoximorphic features in association with reduced soils.

Wetland boundary points were then determined from this information and marked with wire flags or surveyors tape. Appendix A1, Appendix B1 and Appendix C1 contains data forms prepared by Talasaea for representative locations in both upland and wetland locations. The data forms within these appendices are divided by those previously reviewed under the approved BLAs (Appendices A1 and B1), and then those wetlands that have not been previously reviewed (Appendix C1). These data forms document the vegetation, soils, and hydrology information that aided in the wetland boundary determination. CHAPTER 4. RESULTS This section describes the results of our in-house research and field investigations. 4.1 Analysis of Existing Information The following sources provided information on Property conditions based on data compiled from resource agencies and local government. 4.1.1 USGS Quadrangle The Property occurs on the Poverty Bay quadrangle. Weyerhaeuser Pond is mapped immediately north of the Greenline Headquarters building south of the Property. North Lake is mapped adjacent to the east property boundary. No stream features are indicated on this map. 4.1.2 National Wetland Inventory The NWI maps a large wetland complex along the north shoreline of North Lake that is classified as a palustrine scrub-shrub/emergent, persistent, seasonally flooded wetland (PSS/EM1C) and a palustrine emergent (persistent)/palustrine scrub-shrub, semi- permanently flooded (PEM1/SSF) wetland. One stream is mapped along the southern edge of the Property flowing westbound, though this feature is not present in the field. 4.1.3 Natural Resources Conservation Service The NRCS maps one type of soil over the majority of the Property, Alderwood gravelly sandy loam, 0 to 8 percent slopes. Orcas Peat is mapped over a small area in the far eastern portion of the Property near an existing wetland that is adjacent to North Lake. The National Technical Committee on Hydric Soils does not include Alderwood gravelly sandy loam as a hydric soil, though Orcas Peat is identified as a hydric soil. 4.1.4 King County GIS Database King County identifies North Lake as a wetland unit occurring adjacent to the northeast portion of the Property. A stream is (accurately, based on field visits) mapped as exiting North Lake and flowing through Weyerhaeuser Pond before draining south under Highway 18. 4.1.5 SalmonScape and StreamNet SalmonScape maps portions of one (1) stream within the Property, consistent with the inaccurate mapped streams on NWI. SalmonScape does not map any salmonids as Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 6 occurring within the Property nor within North Lake. Mapping of salmonid presence stops roughly 1-mile south of the Property, as the crow flies. StreamNet maps no streams within the vicinity of the property. The outlet for North Lake is shown consistent with the King County GIS database, and also does not note any salmonids as occurring within the Property, or within North Lake. Mapping of salmonids appears to stop more than 1.5 miles downstream. 4.2 Analysis of Existing Conditions – Wetlands The Property west of Weyerhaeuser Way South is currently comprised of the undeveloped lands located around the former Weyerhaeuser Tech Center (Greenline Tech Center). The majority of the Property in this area is a blend of conifer/deciduous mixed forests, though the forested areas are separated by the roads and trails, and a maintained meadow. The stormwater pond on-site collects runoff from much of the existing development (off-site), and conveys the treated water downstream through a man-made channel. The channel (identified as Stream AC) flows southward to its confluence with a perennial stream that connects North Lake to the Weyerhaeuser Pond. North Lake abuts the eastern edge of the Property, and is a Shoreline of the State. The areas on the east side of Weyerhaeuser Way South are separated by an access road to a public boat ramp managed by WDFW. North of this boat ramp road are the northern limits of a large wetland complex that extends to North Lake, surrounded by a coniferous forest. A sewer line easement crosses this area and was replanted some time ago. South/west of the boat ramp road are portions of several wetlands that appear to collect extra runoff from the roadside ditches associated with the boat ramp road through the winter months. Most of these wetlands are not directly associated with North Lake, but ultimately this whole area drains to North Lake. The sewer line easement continues across this portion of the property as well. Much of the Property is underlain by glacial till. This dense material frequently possesses inclusions consistent with redoximorphic features except they lack the diffuse boundaries characteristic of active wetland hydrology. This material is also very difficult to dig through for complete soil profiling. In addition, a number of non-native species of trees occur along the existing gravel roads, having been planted over the years. Talasaea Consultants performed an initial delineation of on-site wetlands beginning in December 2015. Talasaea re-verified the wetland boundaries in April 2016 as the initial delineations were completed after several atypically high rainfall events. Forty-nine wetlands were identified on the Property. The majority of the wetlands have been reviewed and approved under the Greenline Technology Center BLA and the Greenline Headquarters BLA. Remaining wetlands to be reviewed by the City’s consultant are located on the lakeshore properties. Wetland determination data forms and rating forms are separated by BLA, or if they have not been assessed by the City’s consultant, to expedite the review process. Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 7 North Lake occurs adjacent to the Property. One man-made stream (Stream AC) connects the existing stormwater pond to Weyerhaeuser Pond off-site to the south. Two small swales are located at the south end of the meadow that convey water at the southern side of a utility easement to the roadside swales along S 336th Street, while another constructed swale occurs between Wetlands BB and BD (North). The wetland labels are non-sequential as the wetlands were delineated as part of a larger effort. A complete table outlining the wetland classification, size, and other information of all the wetlands can be found in Appendix D. Photographs of typical conditions within the wetlands, including typical uplands and access roads, are included within Appendix E. Wetlands outside of the Shoreline Management Zone (SMZ) have been rated using the Washington State Wetland Rating System for Western Washington (Ecology Publication # 14-06-029). Wetlands occurring within the SMZ along North Lake were rated using the rating system outlined in the Federal Way Revised Code (FWRC) Chapter 15.10 Critical Areas. 4.2.1 Parcel F Parcel F contains all or part of 12 wetlands. Wetland BD (North) and Wetland CD are located along North Lake. These wetlands are dominated by forested and scrub-shrub canopy, primarily red alder (Alnus rubra) and salmonberry (Rubus spectabilis). The remainder of the wetlands are not hydrologically supported by North Lake, rather, by precipitation and shallow groundwater. 4.2.2 Parcel J Parcel J contains portions of three (3) wetlands, which occur on all three lakeshore parcels. 4.2.3 Parcel L Parcel L contains two (2) wetlands, one of which is BD (North), described above. The other wetland is classified as palustrine forested and scrub-shrub sloped wetland. 4.2.4 Parcel BLA 2-3 Parcel BLA 2-3 contains 27 wetlands located either along North Lake, around the former Weyerhaeuser Tech Center, or in the meadow. Wetlands located along North Lake have been previously described in either Parcel L or Parcel F. Wetlands located west of the Tech Center in the forest are mostly palustrine forested or scrub-shrub, and are supported by precipitation and surface water flows. Wetlands located southwest of the Tech Center are supported by an existing stormwater retention pond, which also provides hydrology for Stream AC. The remaining wetlands are located in the meadow adjacent to Interstate 5. The meadow is heavily maintained and currently dominated by pasture grasses including fescues (Festuca spp.), bentgrasses (Agrostis spp.), velvet grass (Holcus lanatus), sweet vernal grass (Anthoxanthum odoratum), and others. Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 8 4.2.5 Parcel BLA 3-1 Parcel BLA 3-1 contains 12 wetlands, which are located in the southern part of the meadow adjacent to Parcel BLA 2-3. Wetlands located in this parcel are palustrine emergent and classified as slope wetlands. 4.3 Analysis of Existing Conditions – Streams and Other Features North Lake, one (1) stream, and three (3) constructed and maintained swales all occur within the Property. The eastern section of the Property is adjacent to North Lake. North Lake is located within the Shoreline Management Zone, which is outlined in Chapter 6. 4.3.1 North Lake North Lake is a Shoreline of the State and is located adjacent to the northeast parcels within the Property. This 50-acre lake is periodically stocked with rainbow trout by WDFW, and has a resident largemouth bass population that is maintained for fishing. While no motorized boats are allowed on this lake, there is a dock at the north end at the WDFW maintained access point. 4.3.2 Stream AC A stormwater pond for the Tech Center collects runoff from approximately 2/3 of the greater Tech Center property. This stormwater pond conveys the treated water downstream through a man-made channel (Stream AC) that extends into the Property before flowing south under South 336th Street to its confluence with Stream HA. The combined streams flow for approximately 600 feet before entering Weyerhaeuser Pond. Weyerhaeuser Pond then discharges south through a structure into a buried pipe that is located underneath the Headquarters building. The flows from this series of streams ultimately enter the Hylebos Creek some two (2) miles south of the Property. This conveyance feature, identified as Stream AC for the purposes of this report, has not been maintained over the years and has become more naturalized, despite the primary source of flow being the stormwater pond discharge. Stream AC starts at the stormwater pond outlet, but also collects water from the adjacent wetlands and uplands. The flow regime of this stream is directly tied to the discharges from the stormwater pond more so than the other hydrologic inputs. While this feature was artificially created, its connection to fish-bearing waters and naturalization over time ensures that this feature has at least the potential to sustain fish habitat. 4.3.3 Non-regulated Swales Several swales have been constructed and are actively maintained across the Property that tie into natural features. A pair of swales (AT1 and AT2) convey water from the sewer line easement north of South 336th Street south to a culvert under South 336th Street, before discharging these waters into Weyerhaeuser Pond. Ditch BC conveys water from Wetland BB to Wetland BD (North) in the lakefront properties.

WILDLIFE AND LISTED SPECIES 5.1 Wildlife Surveys and Assessments The Property was evaluated for wildlife habitat and observations of wildlife were recorded during all field visits since December 2015. The general habitat on-site is a blend of small depressional wetlands, 3rd growth Douglas fir forest with a patchy salal/sword fern understory, and a mixed deciduous forest with a primarily salmonberry understory. An existing stormwater pond occurs adjacent to several wetlands near the west side of the Property, and a naturalized stream originating from the stormwater pond discharge also occurs on-site. North Lake occurs adjacent to the eastern most portion of the project area. No unique habitats occur on-site. Both North Lake and Stream AC have potential habitat for salmonids and other freshwater fish, though no occurrences have been documented. Both features provide fish habitat at a minimum. Though no fish of any species were observed within Stream AC, North Lake is regularly stocked with rainbow trout, and presumably has many other fish species present. Listed species evaluated for effects include the listed salmonids (Chinook salmon, steelhead, and bull trout) to address the potential for downstream water quality impacts. General wildlife observations during field work include: American Robin, Pacific Wren, Canada Goose, Chickadee, Ruby-crowned Kinglet, Red-winged Blackbird, Pileated Woodpecker, Bufflehead, Mallard, American Widgeon, American Crow, American Coot, Pied-billed Grebe, Rufous Hummingbird, mountain beaver (burrows), rabbit, deer, coyote, and bullfrogs. 5.2 Listed Species There are no known listed species occurring on or adjacent to the Property. Listed species (salmonids) do occur downstream in Hylebos Creek. Any stormwater discharges would be treated sufficient to meet or exceed the current Department of Ecology standards prior to being discharged into North Lake or into downstream waterbodies. North Lake is stocked with rainbow trout. Weyerhaeuser Pond off-site to the south of the Property may also be used by bald eagles for foraging, but this pond has previously been recognized as a large stormwater facility that acts as detention and treatment. Salmonids have not been observed in any of the streams, lake, or pond within the greater Federal Way Campus, LLC property. The apparent hindrances restricting salmonid migration into this area appear to be several not-fish-accessible culverts downstream. There is also a long stretch of pipe (roughly 1,600 linear feet) from the Weyerhaeuser pond, under the Headquarters Building, to its outlet just north of Highway 18, that is likely problematic for fish passage. The potential for federally or state listed species occurring within the Property is very low. North Lake and the associated streams have the capacity for salmonids to occur, though accessibility from Hylebos Creek is artificially restricted. North Lake is stocked with rainbow trout, at a minimum. While no salmon species have been observed within North Lake or associated streams that does not preclude the potential for their presence. No impacts within the ordinary high water mark for any stream or lake is proposed as part of this project, though maintenance of an existing stormwater structure Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 10 will be necessary. All stormwater will be treated prior to discharge and conveyance into a fish-bearing water. CHAPTER 6. REGULATORY REVIEW 6.1 Shoreline Management Zone (SMZ) North Lake is listed as a Shoreline of the State, and as such, the adjacent areas are located within the SMZ for the Department of Ecology and the City of Federal Way. Shorelands extend for 200 feet from the ordinary high water mark (OHWM) for North Lake and include Wetland BD North as well as other wetlands that occur within the shorelands. In addition to a 50-foot lakeshore buffer, these areas along the shoreline of North Lake have extra protections under the SMZ, which require additional coordination for any modifications within this area. Wetlands identified within the Shoreline Management Zone are rated under FWRC 15.10.250. Instead of a formal rating system, wetlands must meet certain criteria to be classified as either a Category I, Category II, or Category III wetland (Table 1). Table 1. FWRC Wetland Buffer Requirements in SMZ (FWRC 15.10.250) Wetland Category Wetland Buffer Width Category I 200 feet Category II 100 feet Category III: >10,000 sf 50 feet Category III: 2,500 – 10,000 sf 25 feet Category III: <2,500 sf 0 feet See Appendix D for wetland rating, category, and standard buffer. 6.2 Non-SMZ Wetlands Wetlands occurring outside of the SMZ in Federal Way are currently regulated under FWRC 19.145.420. Wetlands regulated under Chapter 19 of the FWRC were rated using the Washington State Wetlands Rating System for Western Washington (2014). The ratings for wetlands determine the appropriate buffer width requirements as specified in the Federal Way Revised Code. Wetland ratings and rating figures can be found in Appendix A2, B2, and C2 for wetlands within the Tech Center BLA, Headquarter BLA, and remaining wetlands to be reviewed, respectively. Wetlands identified within the Property, but outside of the SMZ, typically rated as a Category III or IV with Habitat Scores ranging from three (3) to six (6). One wetland rated as a Category II, and no wetlands rated as Category I. Wetland setbacks in the FWRC are determined first by Category and then by Habitat Score (Table 2). Lakefront Boundary Line Adjustment (Parcels F, J, L, BLA 2-3, and BLA 3-1) Existing Conditions Report 20 April 2018 Copyright © 2018 Talasaea Consultants, Inc. 1572 Lakefront BLA Ex Conditions Report (4-2018).docx Page 11 Table 2. FWRC Wetland Buffer Requirements Outside of SMZ (FWRC 19.145.420) Wetland Category Wetland Buffer Width (based on Habitat Score) 3-4 5 6-7 8-9 Category I: Bogs and wetlands of high conservation value 190 feet 190 feet 190 feet 225 feet Category I: Forested and based on function score 75 feet 105 feet 165 feet 225 feet Category II 75 feet 105 feet 165 feet 225 feet Category III 60 feet 105 feet 165 feet 225 feet Category IV 40 feet 40 feet 40 feet 40 feet See Appendix D for wetland rating, category, and standard buffer. 6.3 Streams Type F streams under FWRC 19.145.270 require a 100-foot standard buffer. Regulated lakes not identified as a Shoreline of the State (i.e. Weyerhaeuser Pond) require a standard 25-foot buffer under FWRC 19.145.350. Non-regulated drainage features that do not meet the definition of a stream have no associated buffers. CHAPTER 7. SUMMARY The Federal Way Campus, LLC Property is an approximately 74-acre assemblage of five (5) parcels located within the City of Federal Way in King County, Washington. The stormwater pond for the (former) Weyerhaeuser Tech Center occurs within the Property, along with a vacant single family residence, existing gravel roads, and trails for passive recreation. Portions of 49 wetlands on-site, three (3) wetlands off-site, one stream, and North Lake were identified on or adjacent to the Property. North Lake occurs adjacent to the Property, while one (1) stream and three (3) man-made swales occur within the Property.
