Section 404 jurisdictional determinalions. Any proposed impacts to Wetland A will require Corps notification and could trigger Corps and Ecology permit compliance review and approval, dcpcnding on thc sizc and naturc of Ihc impacts. Gencrally, impacts oF 0.10 acrc or morc within jurisdictional wetlands require a pre-discharge notification to the Corps, which invo]ves permit compliance review and approval by d�e Corps and Ecology. Impacts of less than 0.10 acrc gencrally require post-discharge nolification to ihe Corps. Generally, impacts lo wetlands that occur �vithin the Silver Lakc Watcrshed are not allowecl. However, following Section 37.110.B.S.c oC the City of Everett Zoning Code, impacts to Wetland A may Ue allowed if an overall improvcment to wetland functions is achicved through mitigation. Improvement to water quality functions is prcferccd, but impacts may be allowed if other wetland lunctions are improved providing that watcr quality is not degraded. 3.5 PROPOSED INIPACTS Thc proposed project includes a mixecl-usc dcvelopment consisting of retail and multi-family residcntial developme��t. 'Chc dcvelopmcnt consists �f six buildings and parking. Due to building design rcquircments, the project will result in unavoidable permanent impacts to G55 squa�e teet of Wctland A and d,731 square fcet of wctlancUstrcarn buffer. An additional 790 squars fcet of Wetland A and 2,642 square fcet of wetlancUstrcam buffer that occ»rs outside of the building footprint will bc impacted from constniction activitics. Thc portion of Wctland A to be impacted is dominaled by recd canarygrass. Salmonberry, red alder saplings, one l2-inch dbh and one 8-inch dbh quaking aspcn, hvo 8-inch dbh �vcstcm rcd cedars, and one 8-inch dbh red alder are also present within thc we!land area to be impacted. The portion of WcUand A buffer to be impacted is domina(ed Uy Himalayan blackberry and sapling trees. Three 2d-inch to 30-inch dbh black conttonwoods, one 8-inch dbh westem rcd cedar, one 15-inch dbh quaking aspen, and one ]2-inch dbh red alder also occur in the portion of weUand buffer to be impactcd. Encroachment into thc strcam buffer would primarily affect Himalayan blackberry, quaking aspen saplings, and a variety ef grasses. A total of 1 G trees ��ill be impacted from thc permanent anJ constn�ction impacts within the �veUand and buffer areas (Tablc 2). Appendix C identifies the dominant vegetation to be impacted in cach portion of tl�e wetland and buffer areas.
