The Property is comprised of 16 parcels. The Public Land Survey System location of the Property is Section 16, Township 21 North, Range 4 East, and Section 21, 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 March 2017. DETERMINATION: Fifty-nine (59) wetlands were identified on the Property, with an additional 11 wetlands located adjacent to the Property. Sections of three (3) streams (two fish -bearing and 1 non -fish -bearing) and four (4) ditches are located on the Property. North Lake occurs adjacent to the northeastern parcels of the Property. Weyerhaeuser Pond is located within the central portion of the Property just north of the Greenline Headquarters building. 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. North Lake is the source of water for the main stream on -site, while a stormwater pond associated with the Tech Center is the source of water for the other main stream on -site. The 3rd minor stream is sourced by overland flow and wetland discharges, while the four (4) ditches are primarily run-off driven. SOILS: The NRCS maps four map units over the Property: Alderwood gravelly sandy loam, 0 to 8 percent slopes; Alderwood gravelly sandy loam, 8 to 15 percent slopes; Arents, Alderwood material, 0 to 6 percent slopes; and Norma sandy loam. The National Technical Committee on Hydric Soils includes Norma sandy loam as a hydric soil. VEGETATION: The Property is mix of developed areas, conifer and deciduous mixed forests, and open fields. Typical native species present within the forested areas include Douglas fir (Pseudotsuga menziesi►), western red cedar (Thuja plicata), big -leaf maple (Acer macrophyllum), red alder (Alnus rubra), black cottonwood (Populus balsamifera), salmonberry (Rubus spectabilis), vine maple (Acer circinatum), salal (Gaultheria shallon), sword fern (Polystichum munitum), and other native shrub and herbaceous species. Several non-native species of tree are present throughout the property. Invasive species present sporadically throughout the Property include English ivy (Hedera helix), English holly (Ilex aquifolium), and Himalayan blackberry (Rubus armeniacus). Typical vegetation within the wetlands includes red alder, salmonberry and Douglas' spirea (Spiraea douglasi►) with limited amounts of sedges and rushes. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page i Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, TABLE OF CONTENTS Existing Conditions Re ExecutiveSummary ......................................................................................................... i Tableof Contents.............................................................................................................ii Listof Figures ..................................................................................................................fii Listof Tables.................................................................................................................. iii Listof Appendices ........................................ ......... ................. ......................................... iii Chapter1.

PROPERTY DESCRIPTION 2.1 Property Location The Property is comprised of 16 parcels currently owned by Federal Way Campus, LLC (FWC, LLC) identified internally as Parcels K, O, Q, S, T, U, V, W and Z (Figure 2). A complete list of King County Parcel numbers, and their letter association, is provided on Figure 2. The approximate address is 33663 Weyerhaeuser Way South in the City of Federal Way, Washington. The Property is approximately 239 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 Section 16, Township 21 North, Range 4 East, and Section 21, Township 21 North, Range 4 East, Willamette Meridian. The topography of the Property is gently sloping generally from north to the south, and generally from North Lake to the east in a generally south to southwest direction. Many of the currently forested areas are relatively undisturbed, and have been left as the Weyerhaeuser Corporation ("Weyerhaeuser") left them. Any non -forested areas have been significantly disturbed over the years, primarily through the construction of the former Weyerhaeuser Headquarters building, now known as the Greenline Headquarters building, and surrounding areas. The Property is bound to the east by Weyerhaeuser Way South and North Lake. Undeveloped parcels owned by FWC, LLC are adjacent to the north. Interstate 5 abuts the western side of the Property. Highway 18 is adjacent to the south. The Greenline Headquarters building is located near the central portion of this Property along with Weyerhaeuser Pond within the loop made by Weyerhaeuser Road. South 336th Street divides Parcel Q at the north end of the Property, and Weyerhaeuser Way South divides the lakeshore parcels from the remaining parcels. Vacated rights -of -way occur all across the Property along with active and vacated utility easements. 2.2 Existing Property Development The Property is currently developed with the Greenline Headquarters building and associated infrastructure, including parking lots, paved roads, access roads and portions of a private trail system. The Rhododendron Species Botanical Garden and the Pacific Bonsai Museum are both located on the Property. Several other buildings, houses, and outbuildings are located within these parcels. Portions of Parcels K, Q, U, and Z were developed back in the 1950s and 1960s with houses, cross -streets, and utilities, but most of these features were removed upon the purchase of this area by Weyerhaeuser. Many of the northern and eastern portions of these parcels were already developed with residential developments in the 1950s and 1960s, prior to the Weyerhaeuser development of this Property. These houses appear to have been removed as little evidence of their presence remains on -site. Numerous roads cross -crossed the Property, which are now identified on the base survey as vacated rights -of -way. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 2 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report The Greenline Headquarters building was constructed between 1971 and 1972. Construction of the Weyerhaeuser Pond, Weyerhaeuser Road, parking areas, trail system around the pond and main building, realignment of South 336th Street, and the current Weyerhaeuser Way South alignment were all done in association with the design and construction of the Headquarters building. Sometime during the early 1970s, the Weyerhaeuser Pond was excavated. The excavated material was distributed across the areas now identified as the open fields north and south of the Greenline Headquarters building. This resulted in dense glacial till being placed at the soil surface, and the previous upper soil horizons to be buried under as much as 10-feet of fill, as outlined on the original grading plans for the Greenline Headquarters building. This includes the distribution of large amounts of fill from the excavation of Weyerhaeuser Pond over what are now the open meadows north and south of the Headquarters building. Upwards of 10-feet of fill were placed over these areas as they were regraded and recontoured into what one sees today. 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, 2017) (www.wetlandsfws.er.us.gs.,qov/wtlnds/launch.html); • Natural Resources Conservation Service (NRCS), Web Soil Survey (NRCS, 2017)(www.websoilsurvey.nres.usda.gov/appl); ■ King County GIS Database (King County iMap, 2017); • Orthophotography from USDA's National Agricultural Imagery Program (NAIP 2017), Earth Explorer (USGS), and Google Earth; • Washington Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) Mapper; o Salmonscape (WDFW) (http://wdfw.wa.gov/mapping/salmonsrape); 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 3 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existina Conditions • StreamNet (The Pacific States Marine Fisheries Commission) (http://www.streamnet.or /data/interactive-maps-and-.is-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 some of the wetland boundaries in April 2016 once water levels returned to a normal state after the extremely high rains of December 2015. Other wetland boundaries were reevaluated in March 2017, however, due to the excessive rains (almost three times the normal rainfall for this time of year), these reevaluation efforts were inconclusive. Wetland boundaries and ratings were revisited a final time following a site visit on 3 August 2017 with the City's wetland consultant, Environmental Science Associates (ESA). For the purposes of this report, Talasaea evaluated wetlands within the Property and within 100 feet of the Property. Portions of Parcels Q, U, and V were previously included in other applications with the US Army Corps of Engineers and City of Federal Way. 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). Ordinary high water marks (OHWM) were established based on the DOE guidance document Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (DOE Publication #16-06-029, March 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 The National Wetland Plant List. 2016 wetland ratings (Lichvar et al. 2016). 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. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 4 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions 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. Due to the small size of a number of wetlands, not every wetland has a paired set of datasheets. 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. North Lake is mapped adjacent to the northeast property boundary. No stream features are indicated on this map. 4.1.2 National Wetland Inventory The National Wetland Inventory maps North Lake, Weyerhaeuser Pond, two streams, and two (2) wetlands within or adjacent to the Property (Figure 3). North Lake is divided into two (2) non -wetland classifications: Lacustrine, Littoral, Aquatic Bed, Permanently Flooded (L2ABH) and Lacustrine, Limnetic, Unconsolidated Bottom, Permanently Flooded (L1 UBH). Weyerhaeuser Pond is mapped as a Palustrine unconsolidated bottom, permanently flooded, diked/impounded (PUBHh). Two streams are mapped across the Property, both are mapped as Riverine, intermittent, streambed, seasonally flooded (R4SBC). Neither of these streams are mapped accurately. Lastly, two wetlands are shown in the south-central portion of the Property, mapped as Palustrine scrub -shrub, seasonally flooded, diked/impounded (PSSCh) and Palustrine, scrub -shrub, seasonally flooded, excavated (PSSCx). These mapped features are consistent with field -identified features, described below. Additional wetlands are mapped in the general vicinity of the Property but are more than 100 feet from the parcel boundaries. 4.1.3 Natural Resources Conservation Service The NRCS maps four (4) types of soil over the majority of the Property: Alderwood gravelly sandy loam, 0 to 8 percent slopes (AgB); Alderwood gravelly sandy loam, 8 to 15 percent slopes (AgC); Arents, Alderwood material, 0 to 6 percent slopes (AmB); and Norma sandy loam (No) (Figure 4). Weyerhaeuser Pond is not noted on these maps, though North Lake is. It is important to note that the map unit boundaries on the current soils map have not changed from the 1972 Soil Survey of King County, Washington, which was mapped before the Greenline Headquarters building and Weyerhaeuser Pond were constructed. The construction of this building and the pond, and the subsequent distribution of the excess fill material, have significantly changed the mapped soils on -site such that these mapped soils are likely not accurate within the 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 5 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report non -forested areas. Verification of soil map units was not completed during this field investigation. Alderwood gravelly sandy loam (both AgB and AgC) are noted as forming under conifers in glacial deposits. Where the forests are relatively undisturbed, these mapped soils are likely still accurate. The Alderwood soil series is noted as being moderately well drained soils that occur on uplands. Minor inclusions of hydric soils, such as Norma sandy loam and Shalcar muck are noted as occurring within depressions, though these hydric inclusions are less than 10% of the mapped area. Arents, Alderwood material, 0 to 6% slopes, is noted as being the result of shaping during construction (NRCS Soil Survey King County, 1972). This map unit overlaps a building and associated infrastructure located in the southeast corner of the Property that has been present since at least 1964. It appears to have been constructed between 1958 and 1964, though we lack the aerial imagery in the in-between years to verify. The National Technical Committee on Hydric Soils includes Norma sandy loam as a hydric soil. This soil series is noted as occurring along stream bottoms. The Norma sandy loam map unit overlaps an area that was previously identified as wetlands during construction of the Greenline Headquarters building, which was then filled to accommodate the placement of fill material from the pond excavation. This area has since partially developed into wetlands, as described below. 4.1.4 King County GIS Database King County does maps two (2) wetlands on the Property, one of those being Weyerhaeuser Pond. The second wetland is in the southwest corner of the Property and correlates to a wetland flagged during site investigations. North Lake is mapped as a wetland unit occurring adjacent to the northeast portion of the Property. A stream is mapped as exiting North Lake, flowing through Weyerhaeuser Pond and the southwest mapped wetland, before crossing Highway 18. 4.1.5 SalmonScape and StreamNet SalmonScape maps portions of four (4) streams within the Property. Two (2) streams coincide with the inaccurately mapped streams from the NWI. The other two (2) streams coincide with the stream as mapped on the King County GIS database exiting North Lake, through Weyerhaeuser Pond, and continuing south across Highway 18. SalmonScape does not map any salmonids as 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 the streams 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 Talasaea Consultants performed an initial delineation of on -site wetlands and streams 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. Wetland boundaries were adjusted a final time after a site visit with ESA in August 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 6 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Conditions 2017. A total of fifty-nine (59) wetlands were identified on the Property (Sheet W1.0 in Appendix E). A complete table outlining the wetland classification, size, and other information of all the on -site wetlands, as well as the wetland in the immediate vicinity, can be found in Appendix B. The wetland labels are non -sequential as the wetlands were delineated as part of a larger effort. Photographs of typical conditions within the wetlands, including typical uplands and access roads, are included within Appendix C. The Property is mix of developed areas, conifer and deciduous mixed forests, and open fields. Typical native species present within the forested areas include Douglas fir (Pseudotsuga menziesh), western red cedar (Thuja plicata), big -leaf maple (Acer macrophyllum), red alder (Alnus rubra), black cottonwood (Populus balsamifera), salmonberry (Rubus spectabilis), vine maple (Acer circinatum), salal (Gaultheria shallon), sword fern (Polystichum munitum), and other native shrub and herbaceous species. Several non-native species of tree are present throughout the property. Invasive species present sporadically throughout the Property include English ivy (Hedera helix), English holly (Ilex aquifolium), and Himalayan blackberry (Rubus armeniacus). Typical vegetation within the wetlands includes red alder, salmonberry and Douglas' spirea (Spiraea douglasii) with limited amounts of sedges and rushes. Much of this area 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. Much of this glacial till was made more shallow through the construction activities within this immediate area in the past few decades. In addition, a number of non-native species of trees occur along the existing gravel roads, having been planted over the years. 4.2.1 Parcel K Parcel K contains all or part of four (4) wetlands, a portion of BD (South) and all of Wetlands BN, CM, and CN. The outlet of North Lake is also located within Parcel K, and is discussed in more detail below, in Section 4.3. Wetland BD, both BD North (located off -site) and BD South (on- and off -site), occur along North Lake. These depressional and lake -fringing wetlands extend along much of the lake's western shoreline, with significant gaps where the uplands slope directly into the deep lake waters. Wetlands BN, CM, and CN appear at least partially artificial in nature, and are a result of receiving runoff from Weyerhaeuser Way South without clear flows for the water to reach downstream waterbodies. These wetlands are flanked by existing and vacated road rights -of -ways. Typical species within these wetlands include salmonberry and red alder. 4.2.2 Parcel Parcel O only contains a portion of Wetland BD South, which is described above. 4.2.3 Parcel Q Parcel Q contains all or part of 20 wetlands, including small slope and depressional wetlands that occur north of South 336th Street, as well as a series of depressional wetlands that occur around Streams HA and AC south of South 336th Street. Those wetlands located outside of any forested areas are dominated by pasture grasses, 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 7 Greenline Headquarters BLA (Parcels K, O, Q, S. T, U, V, W, Z) Existing Conditions Report typically a mix of rye (Lolium spp.), fescues (Festuca spp.), bentgrasses (Agrostis spp.), velvet grass (Holcus lanatus), sweet vernal grass (Anthoxanthum odoratum), and others. Wetlands within the forested areas are typically salmonberry dominated. Almost all of these wetlands are less than 0.1-acre (4,500 square feet) in size, and many are less than 300 square feet. The streams are discussed in more detail below, in Section 4.3. 4.2.4 Parcel S Parcel S contains the wetlands located around Weyerhaeuser Pond, as well as Weyerhaeuser Pond itself, and several wetlands that occur in the woods to the northeast of the pond. A total of seventeen (17) wetlands. Those wetlands located outside of any forested areas are dominated by pasture grasses, typically a mix of rye, fescues, hair grasses, velvet grasses, sweet vernal grass, and others. Wetlands within the forested areas are typically salmonberry dominated. A single slope wetland occurs at the south end of the meadow south of the Headquarters building, immediately north of Weyerhaeuser Road. The vast majority of these wetlands are also less than 300 square feet with a few larger exceptions. No wetlands are large than of an acre. These are a mix of slope and depressional wetlands. 4.2.5 Parcel T Parcel T contains no wetlands or waterbodies. 4.2.6 Parcel U Parcel U contains all or part of Wetlands DQ, DR, and EE. All three (3) wetlands are less than 0.1-acre in size. Typical species within these wetlands include salmonberry, red alder, and willows (Salix spp.). These wetlands are currently part of an active application for the Greenline Warehouse A project with the City of Federal Way, and were previously identified under Corps Permit NWS-2016-443. 4.2.7 Parcel V Parcel V contains all or part of 10 wetlands, including Wetlands DP, DT, DU, DW, DX, DZ, EB, EC, ED, and EF. These are all depressional wetlands less than 0.1-acre in size. Typical species within these wetlands include salmonberry and red alder. Stream EA also occurs within Parcel V, and is discussed in more detail below in Section 4.3. 4.2.8 Parcel W Parcel W contains five (5) wetlands, including Wetlands GT, GU, GV, HS, and HT. Wetland GT is a riparian and depressional wetland located along the western edge of Stream HA before the stream flows under Highway 18. Wetland GT has multiple cover types, and a wide variety of native species present. Wetland GV is located along the eastern edge of Stream HA, but this slope wetland is different hydrologically and vegetatively from Wetland GT. Wetland GU is an herbaceous wetland located on either side of a drainage feature (Ditch GR) that conveys road runoff from Weyerhaeuser Road to Stream HA to the south. Wetlands HS and HT occur within the rhododendron garden and are artificially created. Wetland HS occurs on a shallow slope uphill from Wetland HT, and could be the result of a broken irrigation pipe, but nothing was found to identify the source of water for this area. Wetland HT occurs where a slope abuts a retaining wall and a swale was constructed that conveys drainage to the south. A portion of this swale has hydric soils and is heavily vegetated. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 8 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Existing Conditions Report 4.2.9 Parcel Z Parcel Z contains a small portion of Wetland BD South, described above. This is the southern limits of Wetland BD South that occur within the Property. 4.3 Analysis of Existing Conditions — Waterbodies Three (3) segments of the main stream exiting North Lake, sections of an additional two (2) streams, four (4) constructed and maintained ditches, and Weyerhaeuser Pond all occur within the Property. A small section of the Property is adjacent to North Lake. North Lake is located within the Shoreline Management Zone, which is outlined in Chapter 5. 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 Weyerhaeuser Pond was constructed in conjunction with the former Weyerhaeuser Headquarters building. 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 HA Stream HA, the outlet of North Lake, occurs across the Property in three (3) segments: between Weyerhaeuser Way South and North Lake, between Weyerhaeuser Way South and Weyerhaeuser Pond, and south by Highway 18 after the pond discharge. North Lake drains towards Hylebos Creek from the southwest portion of the lake. This stream is channelized between Weyerhaeuser Way South and North Lake, and is regularly maintained to remain free of vegetation and has steep side slopes. A culvert under Weyerhaeuser Way South seems to back up water during the heavy rains of the winter months, as the OHWM for this short segment east of the road is much wider than other reaches of this stream. This stream flows under Weyerhaeuser Way South towards Weyerhaeuser Pond, collecting flows from Stream AC on the way. From the Weyerhaeuser Pond, a pipe conveys flows under the Headquarters building and adjacent meadow to the south. The stream reappears above ground at the southern end of the Property where the pipe discharges at a headwall, and continues to flow south towards, and eventually under Highway 18 through a pair of large culverts. Wetlands HA and GT occur adjacent to this stream and receive some of their hydrology from Stream HA. This is a perennial stream that is fish -bearing. While no salmonids are mapped within this stream, nor have any been sighted during site investigations, North Lake is stocked with rainbow trout that could move freely through this stream system. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 9 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report 4.3.4 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. 4.3.5 Stream EA Stream EA is located in the southeast corner of the Property and flows south under the access road/utility easement before continuing under Highway 18. The stream is ephemeral in nature and is supported hydrologically by precipitation and surface water flows from the surrounding uplands and wetlands. A culvert is the main discharge into this stream that conveys water from a French drain system along the road immediately north of the stream. Areas immediately surrounding the stream are dominated by red alder and Himalayan blackberry. 4.3.6 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. There is a constructed ditch (Ditch DS) immediately north of Wetland DR. This ditch was excavated in uplands, as evidenced by the maturity of the adjacent trees, mostly Douglas fir with salal and sword fern in the understory. Another ditch (Ditch GR) is located through Wetland GU that conveys road runoff from Weyerhaeuser Road to Stream HA. CHAPTER 5. REGULATORY REVIEW 5.1 City of Federal Way Zoning Code An existing Concomitant Pre -Annexation Zoning Agreement was developed in 1994 between the City of Federal Way and the Weyerhaeuser Company, which transfers to subsequent landowners. The Concomitant Agreement uses the guidelines outlined in Section 22-1357 of Ordinance 99-353 of the 1994 Federal Way Code (FWC). The 1994 FWC does not provide for any means of wetland rating or evaluating, and provides a single standard buffer to all wetlands. The 1994 FWC has been approved for use 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 10 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report regarding wetlands within Parcels U and V as part of a project that is currently with the City for review. However, the wetlands occurring within the remaining parcels will not use the 1994 FWC to evaluate critical areas or setbacks within the Property. Chapters 15 and 19 of the Federal Way Revised Code (FWRC), as appropriate, have been used to evaluate the wetlands and determine their appropriate buffers not occurring within Parcels U or V. 5.2 1994 FWC and Concomitant Agreement Wetlands Those 13 wetlands occurring within Parcels U and V were evaluated pursuant to the 1994 FWC and Concomitant Agreement. The 1994 FWC requires a standard 100-foot buffer for all wetlands. Major (fish -bearing) streams under this code require 100-foot standard buffers, where minor (non -fish -bearing) streams require a 50-foot standard buffer. 5.3 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 Wetland BD North and Wetland BD South 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. Category I wetlands require a 200-foot buffer, while Category II wetlands require a 100-foot buffer. Category III wetlands greater than 10,000 sf require a 50-foot buffer, and wetlands between 2,500 and 10,000 sf require a 25-foot buffer. Category III wetlands smaller than 2,500 sf do not require a buffer under FWRC. See Appendix B for wetland rating, category and standard buffer. 5.4 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 Property, but outside of the SMZ or Parcels U or V, typically rated as a Category III or IV with Habitat Scores ranging from three (3) to six (6). One wetland rated as a Category ll, and no wetlands rated as Category I. Wetland setbacks in the FWRC are determined first by Category and then by Habitat Score (Table 1). See Appendix B for wetland rating, category and standard buffer. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 11 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report Table 1 FWRC Wetland Buffer Requirements FWRC 19.145.420 Wetland Category Category I: Bogs and wetlands of high conservation value Category I: Forested and based on function score Category II Category III Category IV Wetland Buffer Width based on Habitat Score 3-4 5 6-7 8-9 190 feet 190 feet 190 feet 225 feet 75 feet 105 feet 165 feet 225 feet 75 feet 105 feet 165 feet 225 feet 60 feet 105 feet 165 feet 225 feet 40 feet 40 feet 40 feet 40 feet 5.5 Streams Type F streams under FWRC 19.145.270 require a 100-foot standard buffer.

WILDLIFE SURVEYS AND HABITAT ASSESSMENTS The Property was evaluated for wildlife and habitats concurrently with delineation efforts and observations of additional wildlife were recorded during all field visits since December 2015. The general habitat on the Property is a blend of small depressional, slope, and riparian wetlands, ponds and streams, third -growth Douglas fir forest with a patchy salal/sword fern understory, and a mixed deciduous forest with a primarily salmonberry understory. No unique habitats occur onsite. General wildlife observations during fieldwork included: Birds: 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; Mammals: mountain beaver (burrows), rabbit, deer, coyote; Amphibians: bullfrogs. Multiple site visits since the initial wetland delineations have added to the list of species identified as occurring on the Property, as well as expanding our timeframe over which we have evaluated this Site. No listed species occur on the Property. A bald eagle nest is mapped on the Washington Priority Habitat and Species database as occurring approximately 1,350 feet east of the eastern edge of the Property. Sections of three (3) streams (two fish -bearing and 1 non -fish -bearing) and four (4) ditches are located on 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 12 Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) Existing Conditions Report the Property. North Lake occurs adjacent to the northeastern parcels of the Property. Weyerhaeuser Pond is located within the central portion of the Property just north of the Greenline Headquarters building. 6.1.1 Listed Species - Salmonids Potentially occurring listed species within the Property include the listed salmon species (Chinook salmon, steelhead, bull trout). No evaluation of potential impacts to listed species was conducted for this Property as no development is proposed. Salmonids have not been observed in any of the streams, North Lake, or Weyerhaeuser Pond within the greater FWC, LLC property. Neither SalmonScape nor StreamNet map any salmonid species as occurring within North Lake, though the lake is noted as being stocked by the Washington Department of Fish and Wildlife with rainbow trout. The outlet for North Lake is also not mapped with salmon -presence, neither modeled nor actually present. Mapping of salmonids stops south of the Federal Way Campus property, well south of Highway 18. The apparent hindrances restricting salmonid migration into this area appear to be several not -fish -accessible culverts downstream outside of the FWC, LLC property. 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. 6.1.2 Listed Species - Bald Eagles A bald eagle nest is mapped on the Washington Priority Habitat and Species database as occurring approximately 1,350 feet east of the Site. The location of this nest was field verified, though its use status was not. No eagles were observed in or near the nest at the time of survey through the winter of 2015-2016. The nest occurs on a large tree within a large wetland/upland complex located east of an office park, and is visible from the edge of the adjacent commercial office park. The nest occurs across Weyerhaeuser Way South from the Property, and on the opposite side of the office park from the Property. Bald eagles were removed from the federal endangered species list in 2007, and no longer are protected under the Endangered Species Act. However, bald eagles continue to be protected under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act. These Acts prohibit the "taking" of a bald eagle through direct or indirect actions that may disturb the birds enough to disrupt their breeding, foraging, or nesting behaviors. The existing office park and Weyerhaeuser Way South have been in place for many years, and occur between the Property and the mapped nest. No bald eagle nests occur within the Property. Foraging habitat does occur within the Property. Eagles are most likely to forage in and around North Lake or Weyerhaeuser Pond, or potentially within the open field areas located in the broad area. Bald eagles rarely hunt within densely wooded environments. It is possible eagles may use trees within the Property for roosting. 29 August 2017 Copyright © 2017 Talasaea Consultants, Inc. 1572 HQ BLA Ex Conditions Report (08-29-2017).docx Page 13 11 I I I 1 I Greenline Headquarters BLA (Parcels K, O, Q, S, T, U, V, W, Z) CHAPTER 7.

Westside Prairies: Herbaceous, non -forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in LVDFWPHSreport p.161 -see web link above). Instream; The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. -- Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report - see web link on previous page). Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. — Cliffs: Greater than 2.5 ft (7.6 m) high and occurring below 5000 It elevation. Talus; Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2 0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question B. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0 go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. Y1go to 3 YES - The wetland class is Flats 0ur wetland can be classified as a Flats wetland, use the farm for Depr•essional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). l0 - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be verygradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the Following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number - go to 6 YES --- The wetland class is Riverine OTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YE - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question B. 1. Are the water levels in the entire unit usually controlled by tides except during floods? N9- go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is notscored. This method cannot be used to score functions for estuarine wetlands. 2, The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 64- go to 3 YES - The we iIt ind class is flats your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). 60 go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _XThe wetland is on a slope (slope can be verygradual), ),'.The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, "-The water leaves the wetland without being impounded. NO - go to 5 jff�- The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form — Effective January 1, 2015 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are Filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional S. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO SACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. lfyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the ra ting.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? I O go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is notscored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 6- go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). (54 go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _.The wetland is on a slope (slope can be verygradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO - go to 5 ES The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number �G/'V NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different IIGM classes. For example, seeps at the base of a slope may grade into a rverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT [make a rough sketch to help you decide]. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

Use the following table to identify the appropriate class to use for the rating system if you have several H GM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression _ _ Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE— Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number ' NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE lfyou are still unable to determine which of the above criteria apply to your wetland, or if you have �J more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? `i go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 0 go to 3 YES - The wetland class is Flats I your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). N - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. - go to 5 YES - The wetland class is Slope NO NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Raring Form - Effective January 1, 2015 Wetland name or number Iv G? go to 6 YES - The wetland class is Riverine &TE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO -go to 7 YES The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

N [ go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classif ed as a Freshwater Tidal Fringe use the fortes for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is notscored. This method cannotbe used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO go to 3 YES - The wetland class is Flats 2r'ur wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; —At least 30% of the open water area is deeper than 6.6 it (2 m). N ())- go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. l goes the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verygradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO -go to 5 V 5The wetland class is Slope NOTE: Surface water does not pond in these type of wetlan", "",\cept occasiuually in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Welland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 J, J I Wetland name or numberi_1� NO -go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a rverine floodplain, or a small stream within a Depressional wetland has a zone of Flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN [QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough stretch to help you decide). Use the following table to identify the appropriate class to use For the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional _ Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression _ Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verygradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO-goto5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have ►Wore than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. — Westside Prairies: Herbaceous, non -forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p.161 - see web link above). lnstream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report - see web link on previous page). Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. — Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0,15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question B. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0 go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 0 go to 3 YES - The wetland class is Flats Your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). N [ - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. 0� go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number - NO go to 6 YES - The wetland class is Riverine NO The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet if present, is higher than the interior of the wetland. NO -go to 7 & The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with. multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question S. I. Are the water levels in the entire unit usually controlled by tides except during floods? N 0 - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 01 go to 3 YES - The wetland class is Flats I your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (S ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). 8- go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), JKThe water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO - go to 5 YE5 The wetland class is Slope NOTE: Surfage water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional B. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a DepressionaI wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide).

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? Na - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 0� go to 3 YES - The wetland class is Flats (your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verygradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, y The water leaves the wetland without being impounded. ( � - go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form —Effective January 1, 2015 Wetland name or number X N - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 ES The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit go to 3 YES - The wetland class is Flats I your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; .At least 30% of the open water area is deeper than 6.6 ft (2 m). i - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be very gradual), _The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, _The water leaves the wetland without being impounded. go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update 3 Rating Form - Effective January 1, 2015 Wetland name or number tM 9 - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 CYEJ - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit, classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question B. 1. Are the water levels in the entire unit usually controlled by tides except during floods? ko) go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. lL U - go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). N go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. 'N [' - go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number �/ go to 6 YES - The wetland class is RiverineOt #TE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 *- The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional Depressional + Lake Fringe Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES ' The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a rverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 16 go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the farms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. 1p- go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). 10- go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. 0- go to 5 YES - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number VL (NO)- go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classes the wetland as Depressional for the rating.

In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? N 0 go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. PY goto 3 YES - The wetland class is Flats ur wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). 10 - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Roes the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verygradual), XThe water flows through the wetland in one direction (unidirectional) and usually comes from X seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. NO - go to 5 # - The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number �V NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO go to 3 YES - The wetland class is Flats your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? 4The wetland is on a slope (slope can be verygradual), _The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. 8� go to 5 ES The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number' NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Mature forests - Stands with average diameters exceeding 21 in (53 cm) dbh; crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old -growth; 80-200 years old west of the Cascade crest. — Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p.158 - see web link above). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. — Westside Prairies: Herbaceous, non -forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p.161 - see web link above). Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. — Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report - see web link on previous page). — Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. — Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. — Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Y, Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western Washington and are > 6.5 It (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft (6 m) long.
