According to the federal and state methodologies described above, identification of wetlands is based on a three-factor approach involving indicators of hydrophytic vegetation, hydric soils, and the presence or evidence of persistent hydrology. Except where noted in the manuals, the three-factor approach discussed above requires positive indicators of hydrophytic vegetation, hydric soils, and wetland hydrology, to make a determination that an area is a regulated wetland. Using the aforementioned manuals, the procedure for making a wetland determination include the following: 1.) Examination of the site for hydrophytic vegetation (species present/percent cover); 2.) Examination for the presence of hydric soils in areas where hydrophytic vegetation is present;and 3.)The final step is determining if wetland hydrology exists in the area examined under the first two steps. Per industry standards,Acre Environmental Consulting, LLC examined the entire project site. Per current City of Everett requirements, Acre Environmental Consulting, LLC also assessed adjacent properties within 225 feet of the proposed project limits, to the maximum extent possible without entering adjacent properties. While a detailed assessment of Critical Areas on adjacent properties was not possible due to the lack of legal access, Acre Environmental Consulting, LLC conducted a review of all available information to assess the presence of off-site Critical Areas within 225 feet of the subject site. This review is required by the City of Everett to determine if any regulated Critical Areas exist off-site which would cause associated protective buffers to extend onto the property and affect the development proposal. In addition to on-site field reviews, Acre Environmental Consulting, LLC examined aerial photographs and topographical data (elevation contours) on Snohomish County's SCOPI and SnoScape map systems. Critical Areas Maps produced by the City of Everett, Web soil survey maps produced by the Natural Resources Conservation Service (NRCS), National Wetlands Inventory (NWI) maps produced by the U.S. Fish and Wildlife Service (USFWS), SalmonScape fish distribution maps produced by the Washington Department of Fish and Wildlife (WDFW), and StreamNet fish distribution maps produced by Pacific States Marine Fisheries Commission.
