• Washington Department of Natural Resources Forest Practices Application Mapping Tool (FPAMT): FPAMT does not display any streams on the subject property. The same stream (Edgewater Creek) as the City of Everett map viewer is shown, off -site to the southwest and is a Type F stream. Refer to Figure 5. WA-DNR Forest Practices Application Mapping Tool of Appendix A. • WA-DNR Natural Heritage Program: The resource does not display any Natural Heritage Features for the subject PLSS section (T29N, R04E, S34, W.M.). • USGS National Hrography Dataset: This resource does not identify any streams on site. The same stream as shown by the City of Everett map viewer and the FPAMT (Edgewater Creek) is shown off -site to the southwest of the subject property. See Figure 4: USGSNational Hydrography Dataset Map within Appendix A. METHODOLOGY The Washington State Department of Ecology document Determining the Ordinary High Water Mark for Shoreline ManagementAct Compliance in Washington State (Anderson et al. 2016) was used to determine the presence of any streams on the subject site. Wetland conditions were identified 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methodology described in the Corps of Engineers Wetlands Delineation Manual (Final Report, January 1987), except where superseded by the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual. Western Mountains, Valleys, and Coast Region (Version 2.0, referred to as 2010 Regional Supplement). Our findings are consistent with these manuals. The following criteria descriptions were used in the wetland 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 2.1.1 Hydrophytic Vegetation Criteria The manuals define hydrophytic vegetation as the "sum total of macrophytic plant life that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present." One of the most common indicators for hydrophytic vegetation is when more than 50 percent of a plant community consists of species rated "Facultative" and wetter on lists of plant species that occur in wetlands. 2.1.2 Soils Criteria and Mapped Description The manuals define hydric soils as those that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part. Field indicators are used for determining whether a given soil meets the definition for hydric soils. Sage Homes Northwest LLC - Strickland Properly 3 Critical Area Sludy VVRI #20299 December 20, 2021
