• WDFW Priority Habitat and S ecies (PHS) Interactive Map: The PHS Interactive Map lists Silver Lake as an area with waterfowl concentrations and maps a forested/shrub wetland on the south side of the lake, near the western portion of Wetland A. The portion of Silver Lake Creek near the site is not shown, but the stream is shown approximately 1,000 feet downslope of the site as documented habitat for Coastal Cutthroat Trout. Additionally, the township containing the subject property is listed as habitat for Little Brown Bat and Yuma Myotis. Cutthroat Trout, Little Brown Bat, and Yuma Myotis are not considered threatened or endangered at the state or federal level. • Washington Department of Natural Resources DNA DNR, Forest Practices Application Mapping Tool: This resource maps Silver Lake and Silver Lake Creek in similar locations to other public resources. Silver Lake is identified as a Type S water and Silver Lake Creek is identified as a Type F water. • Snohomish County Planning and Development Services (PDS) Map Portal: The PDS Map Portal maps the same waterbodies and wetlands as other resources. Silver Lake Creek is mapped as a Type F stream. An additional wetland area is mapped within the developed apartment complex west of the clubhouse. This mapping appears inaccurate as the entire mapped wetland is covered in parking and multi-family residential developments. • City of Everett Interactive GIS ortal: This resource maps Silver Lake,Wetland A, and Silver Lake Creek in approximately the same alignment as the other public resources. The Shoreline Master Program designation for the site is shown as Shoreline Residential. • Everett Fish and Wildlife Conservation Areas Man This resource maps Silver Lake as an area with regular large concentrations of waterfowl. 2.2 CRmcAL AREA,$DETEWMNATION METHODOLOGY 2.2.1 Ordinary High Water Mark Deterini ation Methodology The ordinary high water mark (OHWM) of streams was determined using the methodology described in the Washington State Department of Ecology document Determining the Ordinary High WaterMarkfor Shoreline ManagementAct Compliance in Washington State(Anderson et.Al. 2016).Streams are classified according to the water typing system provided in the Washington Administrative Code (WAC), section 222-16-03 L 2.2.2 Wetland Determination Methodology Wetland conditions were evaluated and delineated using routine methodology described in the Corps of Engineers Wetlands Delineation Manual(Final Report;January 1987), except where superseded by the 2010 Regional Supplement to the Cords of Engineers Wetland Delineation Manual• Western Mountains, Valleys, and Coast Region (Version 2.0, referred to as 2010 Regional Supplement). WRI findings are consistent with these manuals. The following criteria descriptions were used in the boundary determination: 1.) Examination of the site for hydrophytic vegetation (species present and percent cover); 2.) Examination of the site for hydric soils; 3.)Determining the presence of wetland hydrology Charter Club Apartments 4 WRI#23061 Critical Area Report&Mitigatim Plan November 6, 2023
