Stephens P <br />Critical Areas Report and Mitigation Plan <br />Photo 3. Stormwater inlet in NW corner of Site showing direct discharge of stormwater <br />onto Site. <br />CHAPTER 3.METHODOLOGY <br />The critical areas analysis of the Site involved a two-part effort. The first part consisted <br />of a preliminary assessment of the Site and the immediate surrounding area using <br />published environmental information. This information included: <br />1) Wetland and soils information from resource agencies; <br />2) Critical Areas information from the City of Everett and Snohomish County; <br />3) GIS analysis of orthophotography and LiDAR imagery; and <br />4) Relevant studies completed or ongoing in the vicinity of the Site. <br />The second part consisted of site investigations where direct observations and <br />measurements of existing environmental conditions were made. Observations included <br />plant communities, soils, and hydrology. Site conditions were compared to previous <br />wetland studies already performed on the Site in previous years. This information was <br />used to help characterize the site and define the limits of critical areas onsite and offsite <br />for regulatory purposes. <br />3.1 Background Data Reviewed <br />Background information from the following sources was reviewed prior to field <br />investigations: <br />• US Fish and Wildlife Service (USFWS), Wetlands Online Mapper (National <br />Wetlands Inventory) (U.S. Fish and Wildlife Service 2019) <br />(www.wetiandsfws.er.usgs.gov/wtlnds/launch.html); <br />6 March 2020 Copyright © 2020 Talasaea Consultants, Inc. <br />1807 CAR V4 Page 4 <br />
