SUBJECT: Existing Conditions and Drainage Study Summary
Dear Eric:
At your request, Talasaea Consultants has prepared the below summary of existing
conditions on Parcel #2121049014 in Federal Way, Washington. This property was initial
evaluated as part of the greater Weyerhaeuser Campus in the winter of 2015-2016.
PROPERTY LOCATION
The property (“Site” hereafter) is a single, approximately 24.3-acre parcel located south of
Highway 18 and west of Weyerhaeuser Way South in Federal Way, Washington (King
County Parcel #2121049014) (Figures 1 and 2). The Public Land Survey System location
of the Site is the SE ¼ of Section 21, Township 21 North, Range 4 East, Willamette
Meridian.
PROPERTY DESCRIPTION AND LAND USE
The Site is undeveloped and completely forested with a native mixed deciduous-coniferous
forest and a large wetland complex (Photo 1). The Site is bordered to the south by single-
family residences and a church, to the east by Weyerhaeuser Way South, and to the north
and west by Highway 18. Southwest of the Site is a large contiguous forested system
associated with Weyerhaeuser Creek on property owned by King County Solid Waste
Division. Site topography is varied and includes an approximately 50 percent west-facing
slope near the eastern property boundary, a horseshoe-shaped depressional area
associated with the large wetland complex in the central area of the Site (described in more
detail below), and a northward protruding ridge in the western area of the Site. Four (4)
wetlands and one (1) stream were identified on the Site. Additionally, one (1) stream
(Weyerhaeuser Creek) was identified offsite to the west.

BACKGROUND INFORMATION
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) (www.wetlandsfws.er.usgs.gov/wtlnds/launch.html);
• Natural Resources Conservation Service (NRCS), Web Soil Survey
(www.websoilsurvey.nrcs.usda.gov/app);
• King County Critical Areas Database (King County, 2019);
• City of Federal Way Critical Areas Database (Federal Way, 2019)
• Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species
(PHS) Database on the Web (wdfw.wa.gov/mapping/phs);
• Washington Department of Natural Resources (DNR) Natural Heritage GIS
database, 2019;
• Fish usage data from SalmonScape
(http://apps.wdfw.wa.gov/salmonscape/map.html), StreamNet
(http://www.streamnet.org/data/interactive-maps-and-gis-data/) and the Northwest
Indian Fisheries Commission (https://geo.nwifc.org/swifd/);
• Orthophotography from Earth Explorer (2019), Google Earth (2019); and Historic
Aerials (www.historicaerials.com, 2019).
The USFWS NWI identifies two wetlands on the Site (Figure 3): A Palustrine forested,
seasonally flooded (PFOC) wetland and a Palustrine scrub-shrub, seasonally flooded

wetland (PSSC). The onsite mapped wetlands correlates to Wetland CR/CS (described
later), which is located in the horseshoe-shaped topographic depression. NWI also maps a
Palustrine forested, seasonally flooded, diked/impounded wetland and a Palustrine scrub-
shrub, seasonally flooded, diked/impounded wetland as occurring approximately 75 feet
southwest of the Site and west of the Site across Highway 18, respectively. King County,
Federal Way, and WDFW PHS all identified the aforementioned wetland features on their
databases.
King County and Federal Way also map a southward-flowing stream west of the Site, which
corresponds with Weyerhaeuser Creek, but do not map any streams on the Site.
Salmonscape, StreamNet, and the Northwest Indian Fisheries Commission, do not map any
features on, or within a 300-foot vicinity of, the Site.
The NRCS maps three soil types as occurring onsite (Figure 4). Alderwood gravelly sandy
loam, 0-8 percent slopes is mapped throughout the majority of the Site. However, a portion
of the southwest area of the Site is mapped as Alderwood gravelly sandy loam, 8-15 percent
slopes, and a small area in the northeast of the Site is mapped as Shalcar muck. Of these
three soil types, Shalcar muck is considered a hydric soil by the National Technical
Committee for Hydric Soils. The area mapped as Shalcar muck is generally consistent with
the location of Wetland CQ (see below for more details).
FIELD INVESTIGATIONS
We evaluated the Site on 22 December 2015 and again on 22 February 2019. Four (4)
wetlands (Wetlands CR/CS, CP, CQ, and F) and one (1) stream (Stream A) were identified
onsite. Additionally, one (1) stream was identified offsite to the west (Weyerhaeuser Creek)
(Figure 5). No other wetlands or streams were identified on or adjacent to the Site that
would extend additional buffers onto the Site. Features are summarized in the Critical Area
Summary Table (Table 1) below.
The routine approach described in the Regional Supplement to the Corps of Engineers
Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (U.S. Army
Corps of Engineers, 2010) was used as a baseline for evaluating the Site for the presence
of wetlands. Wetlands were rated using the Washington State Wetland Rating System for
Western Washington (Hruby 2014), but buffers were assigned according to the 1994
Federal Way City Code (FWCC) and the Concomitant Zoning Agreement (CZA). Wetland
rating forms are attached (Attachment 1).
The ordinary high-water mark (OWHM) for streams was determined using the methodology
described by Washington State Department of Ecology’s “Determining the Ordinary High
Water Mark on Streams in Washington State” (Olson and Stockdale 2016). Wetlands and
streams were typed according to FWRC §19.145.260. Stream buffers were assigned
according to the 1994 FWCC and the CZA. The OHWM of the stream flowing through
Wetland CR/CS was not delineated in the field due to high water levels during site visits,

which precluded a clear determination of the physical OHWM. The entire system becomes
a slough after large rain events with stream waters extending well into the adjacent
wetlands.
WETLAND CR/CS
Wetland CR/CS is a large (approximately 3.1-acre) wetland complex with forested, scrub-
shrub, aquatic bed, and emergent components. The wetland is almost wholly contained
within the Site, except for the northernmost portions of the horseshoe shaped wetland,
which extend north of the northern property line into the Highway 18 right-of-way. Typical
vegetation in Wetland CR/CS includes red alder (Alnus rubra), western red cedar (Thuja
plicata), salmonberry (Rubus spectabilits), spirea (Spiraea douglasii), and slough sedge
(Carex obnupta). Hydrology for the wetland is supplied primarily by overbank flooding from
Stream A, with secondary inputs from direct road runoff from Highway 18, groundwater, and
surface water contributions from the adjacent steep slopes. Road runoff from Highway 18
sheet flows into the wetland from the adjacent right-of-way during rain events. There are
several locations where excess water from the upslope wetlands (CQ and F) overflows
towards Wetland CR/CS.
Wetland CR/CS rated as a Category II wetland with a habitat score of 7. Federal Way
Category II wetlands with habitat scores of 6 to 7 require a standard 150-foot buffer per
FWRC §19.145.420(2). However, under the 1994 FWCC and CZA, a 100-foot standard
buffer would apply.

15020 Bear Creek Road Northeast • Woodinville, Washington 98077 • Bus: (425)861-7550 Fax: (425)861-7549
WETLAND CP
Wetland CP is a small (3,146 square-foot) forested wetland located adjacent to the eastern
property boundary. This wetland is located in relative isolation from other critical areas in
the area. This wetland has no direct (surface) connections to any of the other on-site
wetlands. Typical vegetation in Wetland CP includes red alder, salmonberry, spirea, and
evergreen blackberry (Rubus laciniatus).
Soils in Wetland CP are generally black (10YR 2/1) to 4 inches below the surface. Surface
water ponding up to 18 inches above the soil surface made it difficult to obtain a soil sample
deeper than 4 inches. The soil within the boundary of Wetland CP was assumed to be
hydric based on strong hydrology indicators. Hydrology for Wetland CP is supplied primarily
by groundwater and precipitation, as well as stormwater inputs from the east. The wetland
has no surface outlet and ponded areas exist during parts of the growing season, as
evidenced by Hydrology Indicator A1 (Surface Water) during field visits.
This wetland was rated as a Category III wetland with a habitat score of 4. Federal Way
Category III wetlands with habitat scores of 4 or less require a standard 80-foot buffer per
FWRC §19.145.420(2). However, under the 1994 FWCC and CZA, a 100-foot standard
buffer would apply.

WETLAND CQ
Wetland CQ is a large (33,704 square-foot (0.77 ac)) wetland with forested and scrub-shrub
components, located adjacent to the eastern property boundary on a topographic shelf north
of Wetland CP. Typical vegetation in Wetland CQ includes red alder, Oregon ash (Fraxinus
latifolia), and salmonberry.
Soils in Wetland CQ were assumed to be hydric based on strong hydrology indicators. A
soil sample could not be taken due to surface water ponding of over 18 inches within the
wetland. Hydrology for Wetland CQ is supplied primarily by groundwater and precipitation,
as well as stormwater inputs from the east. A natural pop-off location in the southwest
corner allows some water to discharge from this wetland to Wetland CR/CS and Stream A,
which are located downslope to the west of Wetland CQ.
This wetland was rated as a Category II wetland with a habitat score of 5. Federal Way
Category II wetlands with habitat scores of 5 require a standard 100-foot buffer per FWRC
§19.145.420(2). Under the 1994 FWCC and CZA, a 100-foot standard buffer would also
apply.
Photo 4: Wetland CQ, typical conditions.
WETLAND F
Wetland F is an 8,843 square-foot scrub-shrub wetland located adjacent to the eastern
property boundary, south of Wetland CP. Typical vegetation in Wetland F includes
salmonberry and spirea.

15020 Bear Creek Road Northeast • Woodinville, Washington 98077 • Bus: (425)861-7550 Fax: (425)861-7549
Soils in Wetland F were assumed to be hydric based on strong wetland hydrology
indicators. Surface water ponding between 2 and 3 feet above the soil surface made it
difficult to obtain a soil sample. Hydrology for Wetland F is supplied primarily by
groundwater and precipitation. Similar to Wetland CQ, Wetland F has a naturally restricted
surface water outlet west to the large Wetland CR/CS complex to the west.
This wetland was rated as a Category III wetland with a habitat score of 5. Federal Way
Category III wetlands with habitat scores of 5 require a standard 80-foot buffer per FWRC
§19.145.420(2). However, under the 1994 FWCC and CZA, a 100-foot standard buffer
would apply.
STREAM A AND DRAINAGE
Stream A begins near the northeast corner of the Site and appears to start with multiple
stormwater discharge locations into a relatively small area within the Highway 18 ROW. A
culvert was mapped by WDFW (Site ID 932924, WDFW Fish Passage and Diversion
Screening Inventory Database, Attachment 2) that identifies a culvert at a location
consistent with the start of this wetland/stream system. However, WDFW notes “…culvert
goes under Highway 18 and takes a 90 degree turn under overpass…” so it is unclear
exactly from where this culvert receives water. This WDFW report also misidentifies this
stream as one that is piped underneath the (former) Weyerhaeuser building (now
Woodbridge Headquarters Building).
A culvert inlet exists on the north side of Highway 18, more or less north of this culvert
outlet, that was mapped as part of the Federal Way Campus, LLC Woodbridge Buildings A
and B projects. This culvert is not mapped by WDFW. The below map was provided in a
report titled Weyerhaeuser Headquarters Site, Conditions and Considerations, Existing
Public Sector Services to and through Weyerhaeuser Site Which Affect Next Use Effort,
January 2015, prepared by the City of Federal Way in conjunction with other local utilities. A
storm sewer network map was provided on Page 25 of this PDF, and a portion of this map is
provided as Figure 1 below. This map inaccurately reflects some of the drainage patterns of
this area, but does show the stormwater discharges into the Site.
Based on this more in-depth review of existing data about these culverts, it appears that the
existing drainage (Stream EA) within parcel #3142600200, which was described in the
Critical Areas Report and Buffer Management Plan produced by Talasaea Consultants on
24 August 2017 (File #16-102947-UP and #16-10248-SE), is simply one of several
drainages that converge near the northeast corner of the Site to become Stream A through
this Site.

Figure 1. Map of Storm Sewer Network, Wyerhaeuser Campus, 2015 Conditions and Considerations Report.
Once Stream A enters the Site from the Highway 18 ROW, it flows generally westward in a
horseshoe shape through Wetland CR/CS (Figure 5). At the end of Wetland CR/CS,
Stream A enters a 36-inch diameter concrete culvert (WDFW Site ID 932912) that directs
flow to the southwest for approximately 775 feet within the Highway 18 ROW. After exiting
the culvert, Stream A flows above ground in the Highway 18 ROW to the southwest for
approximately 75 feet before comingling with Weyerhaeuser Creek. The confluence of
these stream systems occurs at the outlet of Weyerhaeuser Creek from a twin culvert
system that directs water south underneath Highway 18 (WDFW Site ID 996277).
Stream A has a direct connection to Weyerhaeuser Creek, a fish bearing water, and is
therefore classified as a Type F water throughout the Site based on the known connections.
Federal Way Type F streams require a standard 100-foot buffer per FWRC §19.145.270(1).
The 1994 FWCC and CZA also require a 100-foot standard buffer for major (fish-bearing)
streams.
WEYERHAEUSER CREEK (OFFSITE)
Weyerhaeuser Creek is located approximately 225 feet southwest of the Site at its closest
point. The headwaters of Weyerhauser Creek include North Lake and associated wetlands
and tributaries. Two (2) streams converge north of, and flow into, Weyerhaeuser Pond. An
approximately 1,690-foot pipe serves as the outlet of Weyerhaeuser Pond and directs water
under the headquarter building to a wetland system south of Weyerhaeuser Road and north
of Highway 18. The outlet of the pipe is the beginning of Weyerhaeuser Creek proper,
which flows south through a wetland for approximately 925 feet before entering the twin
culvert system that passes underneath Highway 18 (WDFW Site ID 996277).

15020 Bear Creek Road Northeast • Woodinville, Washington 98077 • Bus: (425)861-7550 Fax: (425)861-7549
Once Weyerhaeuser Creek exits the twin culvert system, it comingles with Stream A west of
the Site and continues to flow south for approximately 1.27 river miles before comingling
with West Hylebos Creek, west of Highway 161. This system collectively becomes East
Fork Hylebos Creek where these streams converge with the stream outlet of Lake Killarney
some distance south of the Site.
Weyerhaeuser Creek is classified as a Type F water because of its direct connection with
West Hylebos Creek, which has document populations of fall-run Chinook salmon
(Oncorhynchus tshawytscha). Federal Way Type F streams require a standard 100-foot
buffer per FWRC §19.145.270(1). The 1994 FWCC and CZA also require a 100-foot
standard buffer for major (fish-bearing) streams. The buffers of Weyerhaeuser Creek do not
extend onto this Site.
TYPICAL UPLANDS
The majority of the site is dominated by a second-growth mixed deciduous-coniferous
upland forest. Typical upland species include: Douglas fir (Psuedotsuga menziesii), red
elderberry (Sambucus racemosa), big -leaf maple (Acer macrophyllum), red alder (Alnus
rubra), creeping buttercup (Ranunculus repens), sword fern (Polystichum munitum), red
huckleberry (Vaccinium parviflorum), bracken fern (Pteridium aquilinum), trailing blackberry
(Rubus ursinus), Pacific bleeding heart (Dicentra formosa), Indian plum (Oemleria
cerasiformis), cascara (Frangula purshiana), creeping mahonia (Mahonia nervosa), and
salal (Gaultheria shallon).
Typical upland soils from 0 to 20 inches below the soil surface are a brown silt loam with no
evidence of redoximorphic features.

SUMMARY
The Site is an undeveloped forested parcel located south of Highway 18 and west of
Weyerhaeuser Way South, in Federal Way. Four wetlands (Wetlands CR/CS, CP, CQ and
F) and one stream (Stream A) occur onsite. Additionally, one stream (Weyerhaeuser Creek)
occurs offsite to the west (Table 1). Drainage on the Site is primarily directed to Stream A
and Wetland CR/CS, which conveys water offsite to the west through a culvert to the
Weyerhaeuser Creek drainage system.
We trust that the information presented here sufficiently addresses your needs at this time.

NFB = no potential salmonid use, BB = both banks, LB = left bank looking downstream, RB = right bank looking downstream, US
or U/S = upstream, DS or D/S = downstream, WSDrop = water surface drop, BFW = bankfull width, OHW = ordinary high water,
SLW = scour line width, CMP = corrugated metal pipe, Qfp = fish passage flow, V&D = Velocity and Depth, ROW = Right of Way
The FPDSI database often uses default values such as ‘-99.99’ or ‘-999’ to represent null values.
