The subject property consists of one tax parcel situated in the Northeast ¼ of Section 11, Township 21 North, Range 03 East, W.M (King County Tax Parcel 6613500030). SVC investigated the site to support with environmental permitting for the subject property following a landslide event that occurred in December 2022. This technical memorandum has been prepared to document the results of the assessment. Figure 1. Subject Property Location. Subject Property Location 2583.0001 SW Dash Point Road 2 Soundview Consultants LLC Shoreline, Wetland, and Fish and Wildlife Habitat Assessment November 7, 2023 Background Data Prior to the site investigation, SVC staff conducted background research using the Washington Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) database, WDFW and Northwest Indian Fisheries Commission (NIFC) Statewide Washington Integrated Fish Distribution (SWIFD) mapping tool, WDFW forage fish survey map, Washington Department of Natural Resources (DNR) stream typing, eelgrass, and kelp mapping inventories, the U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI), Natural Resource Conservation Service (NRCS) soil survey, King County Stream and Wetland Inventory, and Federal Emergency Management Agency (FEMA) mapped floodplain areas. The King County Sensitive Areas Map (Attachment B1), USFWS NWI Map (Attachment B2), WDFW PHS Map (Attachment B3), and DNR Stream Typing Map (Attachment B4) identify Joes Creek offsite over 300 feet east of the subject property. DNR identifies Joes Creek as a Type F (fish- bearing) water. The WDFW SWIFD Map (Attachment B5) identifies documented presence of coho salmon and notes steelhead trout, pink salmon, fall chum and Chinook salmon as gradient accessible within Joes Creek. Additionally, the WDFW PHS Map noted the area surrounding Joes Creek as a biodiversity corridor and the shoreline of the Dumas Bay as potential estuarine and marine wetlands. The King County Sensitive Areas Map additionally mapped the subject property shoreline as a potential erosion hazard. The DNR Eelgrass Inventory (Attachment B6) identifies patchy eelgrass fringe along the subject property shoreline while the DNR Kelp Inventory (Attachment B7) does not identify any kelp presence onsite. Further, the WDFW Forage Fish Map (Attachment B8) does not identify any potential forage fish spawning habitat on the subject property. The FEMA Floodplain Map (Attachment B9) identifies the FEMA 100-year floodplain (Zone VE; elevation 16 feet) associated with Dumas Bay along the northern boundary of the subject property. The National Marine Fisheries Service (NMFS) identifies critical habitat for Puget Sound (PS) Chinook salmon, Bull trout, and rockfish along the subject property shoreline, while the USFWS Information for Planning and Consultation (IPaC) tool identifies the potential presence of marbled murrelet (Brachyramphus marmoratus), Yellow-billed Cuckoo (Coccyzus americanus) and Bull trout (Salvelinus confluentus) within the vicinity of the subject property. The NRCS soil survey map (Attachment B10) identifies two soil series on the subject property: Alderwood and Kitsap soils, very steep (AkF), and Indianola loamy sand, 5 to 15 percent slopes (InC). Both Alderwood and Kitsap soils, very steep and Indianola loamy sand, 5 to 15 percent slopes are listed as non-hydric on the NRCS hydric soils list; however, Indianola loamy sand, 5 to 15 percent slopes is identified with up to 2 percent inclusions of hydric Norma soils (NRCS, n.d). Methods A formal site investigation was performed by qualified SVC staff on May 4, 2023 and consisted of a walk-through survey of the subject property and accessible areas within 300 feet of the site for potentially regulated wetlands, fish and wildlife habitat, and/or priority habitat and species. Wetlands, streams, and select fish and wildlife habitats and species are regulated features per City of Federal Way Revised Code (FWRC) Chapter 19.145 Environmentally Critical Areas, and shorelines are regulated under FWRC Chapter 15.05 Shoreline Management, and subject to restricted uses/activities under the same titles. Critical area determinations were made using observable vegetation and hydrology in conjunction with data from background research and various ortho-photographic resources. 2583.0001 SW Dash Point Road 3 Soundview Consultants LLC Shoreline, Wetland, and Fish and Wildlife Habitat Assessment November 7, 2023 Wetland presence/absence was determined in accordance with FWMC 19.145.410 and as outlined in the U.S. Army Corps of Engineers’ Wetlands Delineation Manual (Environmental Laboratory, 1987) and modified according to the guidelines established in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region, Version 2.0 (USACE, 2010) and Field Indicators of Hydric Soils in the United States (NRCS, 2018). Ordinary high water mark (OHW) determinations were made using the WSDOE’s guidance detailed in Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Anderson et al., 2016) and the Revised Code of Washington (RCW) 90.58.030(2)(b) and WAC 173-22-030(5). To mark the centerline or banks of potentially-regulated waterbodies, blue surveyor’s flagging was alpha-numerically labeled and tied to vegetation. The fish and wildlife habitat assessment was conducted during the same site visits by qualified fish and wildlife biologists. The experienced biologists made visual observations using stationery and walking survey methods noting any special habitat features and direct and indirect signs of fish and wildlife activity (e.g. nesting, foraging, and migration/movement). Special attention was given to assessing the presence of fish and wildlife habitat conservation areas outlined under FWRC 19.145.260. Precipitation Precipitation data was obtained from the National Oceanic and Atmospheric Administration (NOAA) weather station at the Sea-Tac Airport in order to acquire percent of normal precipitation during and preceding the site investigation. A summary of data collected is provided in Table 1. Table 1. Precipitation Summary1 Site Visit Date Day Of Day Before 1 Week Prior 2 Weeks Prior 30 Days Prior (Observed/Normal) Year to Date (Observed/Normal)2 Percent of Normal (Month/Year)l3 5/4/2023 0.05 0.00 0.08 1.02 3.58/3.10 27.50/33.11 115/83 1. Precipitation levels provided in inches. Data obtained from NOAA (https://www.weather.gov/wrh/climate?wfo=sew) for the Sea-Tac Airport. 2. Year-to-date precipitation for site investigation is for the 2022/2023 water year from October 1st to the site visit date. 3. Percent of normal is shown for the 30 days prior to the site investigation and for the 2022/2023 water year. Precipitation levels during the May 2023 site investigation were within the statistical normal range (70 to 130 percent of normal) for both the 30 days prior and the 2022/2023 water year (115 and 83 percent of normal, respectively). This precipitation data suggests that hydrologic conditions were relatively normal during the site investigations. Such conditions were considered in making professional wetland determinations. Results The subject property consists of one parcel along the shoreline of Dumas Bay in south Puget Sound. The property is currently developed with one single-family residence and associated infrastructure. Single-family residential parcels adjoin the subject property to the east and west, while Southwest Dash Point Road abuts to the south, and Puget Sound to the north. Topography onsite gently slopes along the southern property boundary until reaching the waterward edge of the residence which sits at the top of a steep slope that descends to the shoreline (Attachment B11). Elevations onsite range from 110 feet above mean sea level (amsl) on the southern boundary to 10 feet asml along the subject property shoreline. 2583.0001 SW Dash Point Road 4 Soundview Consultants LLC Shoreline, Wetland, and Fish and Wildlife Habitat Assessment November 7, 2023 The site investigation identified the shoreline of Puget Sound along the northern portion of the subject property, which has observed eelgrass, a regulated critical salmonid habitat. Joes Creek was identified approximately 350 feet offsite to the east of the site, beyond the formal assessment area. Upland Characterization No wetlands were identified on the subject property. Vegetation on the southern portion of the site surrounding the single-family residence is dominated by maintained lawn, ornamental plantings and non-native invasive species including Himalayan blackberry (Rubus armeniacus), English ivy (Hedera helix) and butterfly bush (Buddleia davidii). Vegetation on the steep slope along the northern portion of the subject property is dominated by red alder (Alnus rubra), big leaf maple (Acer macrophyllum), osoberry (Oemleria cerasiformis), salmonberry (Rubus spectabilis), and non-native invasive English ivy. Lesser amounts of beaked hazelnut (Corylus cornuta), oceanspray (Holodiscus discolor) and sword fern (Polystichum munitum) were also observed. Given the lack of potential wetlands mapped onsite and dominance of a Facultative-Upland (FACU) and Facultative (FAC) mixed plant community, further analysis of soils and hydrology was not required. Marine Shoreline The shoreline of Dumas Bay of south Puget Sound was identified along the northwestern portion of the site. This portion of shoreline is designated as Urban Conservancy. The shoreline is currently armored with a riprap bulkhead. Beach substrate consists of fine sand in the upper shore zone and silty sands in the lower shore zone. A small patch of non-native eelgrass (Zostera japonica) (approximately 4,000 square feet in size) with less than 10 percent cover as identified approximately 60 feet waterward of the delineated OHWM of the shoreline. Few occurrences of sea lettuce (Ulva sp.) and Turkish towel (Chondracanthus sp.) were also observed at less than 1 percent cover in waterward areas. The riparian zone along the steep slope above the OHWM is dominated by red alder, big leaf maple, osoberry, salmonberry and non-native invasive English ivy. Lesser amounts of beaked hazelnut, oceanspray, and sword fern were also observed. Evidence of the landslide that occurred in December of 2022 was observed entirely between flags OHW-2 and OHW-3, within a 42-linear-foot area. However, the landslide affected only a 16-linear-foot-wide area landward of the shoreline on the hillslope. The exposed riparian slope area of compacted clay subsoil is entirely devoid of vegetation. Fish and Wildlife Habitat Assessment Per FWRC 19.145.260, Fish and Wildlife Conservation Areas (FWHCAs) include streams, regulated lakes, areas with state or federally designated endangered, threatened, and sensitive species have a primary association, state priority habitats and areas associated with priority species, and habitats and species of local importance. NMFS identifies critical habitat for Puget Sound (PS) Chinook salmon, Bull trout, and rockfish along the subject property shoreline, while the USFWS IPaC tool identifies the potential presence of marbled murrelet, Yellow-billed Cuckoo and Bull trout within the vicinity of the subject property. No suitable habitat for yellow-billed cuckoo or marbled murrelet is present within the vicinity of the site. However, suitable habitat conditions including overhanging vegetation for shading and eelgrass beds are present in the upper and lower shore zones for utilization by Puget Sound Chinook salmon, bull trout, and rockfish species. 2583.0001 SW Dash Point Road 5 Soundview Consultants LLC Shoreline, Wetland, and Fish and Wildlife Habitat Assessment November 7, 2023 Regulatory Considerations Local Critical Areas Requirements As a regulated shoreline, Dumas Bay is subject to shoreline environment designations that implement policies and regulated for proposed uses and developments. The residential shoreline of Dumas Bay which extends onsite is designated as Urban Conservancy, and as such is subject to a 50-foot shoreline setback per the FWRC 15.05.070(6). All land within 200 feet of the OHWM is further identified as shorelands zone and subject to the standards and policies under FWRC Chapter 15.05 Shoreline Management. Additionally, FWRC 15.05.090(3)(e) requires all land shoreline setback are be considered a vegetation conservation area, subject to regular maintenance of vegetation required per FWRC 15.05.075(3). Eelgrass beds identified within the intertidal region waterward of the subject property shoreline are considered critical salmonid habitat per FWMC 15.05.030 and as such are subject to certain development standards outlined in FWMC 15.05.040(5) to avoid or minimize impact to the habitat. These buffers apply to all proposed development, repairs, and stabilization measures onsite. Table 3.

Buffer width based on residential use of the shoreline per FWRC 15.05.070(6). State and Federal Considerations On January 18, 2023, USACE and EPA published a revised definition of “Waters of the United States.” The revised rule becomes effective on March 20, 2023. Under the 2023 revised rule, Waters of the United States is described as follows (USACE and EPA, 2023): (a) Waters of the United States means: (1) Waters which are: (i) Currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; (ii) The territorial seas; or (iii) Interstate waters, including interstate wetlands; (2) Impoundments of waters otherwise defined as waters of the United States under this definition, other than impoundments of waters identified under paragraph (a)(5) of this section; (3) Tributaries of waters identified in paragraph (a)(1) or (2) of this section: (i) That are relatively permanent, standing or continuously flowing bodies of water; or (ii) That either alone or in combination with similarly situated waters in the region, significantly affect the chemical, physical, or biological integrity of waters identified in paragraph (a)(1) of this section; (4) Wetlands adjacent to the following waters: (i) Waters identified in paragraph (a)(1) of this section; or (ii) Relatively permanent, standing or continuously flowing bodies of water identified in paragraph (a)(2) or (a)(3)(i) of this section and with a continuous surface connection to those waters; or (iii) Waters identified in paragraph (a)(2) or (3) of this section when the wetlands either alone or in combination with similarly situated waters in the region, significantly affect the chemical, physical, or biological integrity of waters identified in paragraph (a)(1) of this section; 2583.0001 SW Dash Point Road 6 Soundview Consultants LLC Shoreline, Wetland, and Fish and Wildlife Habitat Assessment November 7, 2023 (5) Intrastate lakes and ponds, streams, or wetlands not identified in paragraphs (a)(1) through (4) of this section: (i) That are relatively permanent, standing or continuously flowing bodies of water with a continuous surface connection to the waters identified in paragraph (a)(1) or (a)(3)(i) of this section; or (ii) That either alone or in combination with similarly situated waters in the region, significantly affect the chemical, physical, or biological integrity of waters identified in paragraph (a)(1) of this section. Dumas Bay is regulated under Section 404 of the Clean Water Act (CWA) as Waters of the United States under the March 20, 2023 rule. On May 25, 2023, the U.S. Supreme Court issued a decision affecting the definition of Waters of the United States in Sackett Et Ux. V Environmental Protection Agency Et Al. While USACE is in receipt of the Supreme Court decision, no formal, revised definition of Waters of the United States has been issued at the time of this report drafting. The proposed project therefore continues to assume that the onsite Dumas Bay is considered a Waters of the United States and regulated as surface waters of the state by the WSDOE under the Revised Code of Washington (RCW) 90.48. All work below the OHW of Dumas Bay will require authorizations from the USACE or WSDOE. Conclusions The site investigation in May of 2023 identified the residential shoreline of Dumas Bay on the northwestern boundary of the subject property which is subject to a 50-foot shoreline per FWRC 15.05.070(6). Eelgrass beds identified onsite are regulated as critical salmon habitat and subject to development standards described in FWMC 15.05.040(5). Additionally, the majority of the subject property is located within the 200-foot shorelands zone. If you have any further questions, please contact me at your earliest convenience.
