3. The Mukilteo School Dislrict has commer�ted that the project will adversely impact the School District (see attached letter). The applicant musl negotiate with the School District regarding a mitigation agreement. Prior to finalization of the SEPA determination, written letter or agreement must be provided to the City by the School District or applicant. (SEPA Public Services and Utilities Policies) 4. Wetlands (SEPA Earth, Land, Plants and Water Policies) I. Site Descriation • Category II Wetland and Category III Stream A Category II Wetland with an associated Category III Stream are located along the southwest corner of the subject site. The Category III Wetland is a riparian wetland associated with the on-sile tributary of Swamp Creek. This Category III Stream enters the property on the west side and Flows soulheasterly, draining out at a culvert running under 112"' Street on the south side of lhe site. The Category III Stream is an upper tributary of Swamp Creek. This stream is naturally intermittent during years of normal rainfall and this upper tributary is not used by salmonids due to a downstream blockage. Category II Wellands in the City of Everett are protecled by 75-(oot buffers. Category III Streams in the City of Everelt are protecled by 25-foot buffers. II. Functions and Values Assessment • Stormwater StoragelFloodflow Attenuation/Waler Quality Due to the gentle topography, this wetland serves to collect storm runoff and release it over a longer period of time. As this stream ilows through this wetland, water spreads out over the wetland area. This serves to slow the fiow of the stream and reduce peak flows downstream. During periods of low precipilation, water flows from the wetland to lhe stream, helping to maintain base glows. This wetland also improves waler quality. As water slows and passes througli the vretland, the lower velocity and lhe dense vegetation serve to remove sediment and poliulants. The lack o(dense vegetalion in lhis wetland minimally limits these (unclions. Overali, this welland provides good values for these funclions. • Wildlife Habitat Due to the size of the wetland, ihe density and structure of the vegetation, and the location in an urban area, this wetland provides good habitat for wildlife. Habitat values in this area are limited by lhe proximily to major thoroughfares and development. Due to the urban location, the most likely animals io utilize this wetland are birds amphibians and small mammals. As this region becomes more developed, urban wetlands such as this wiil increasingly be relied upon as valuable nalural areas. • Wetland and Stream Buffer Due to the past clearing, portions o(the site have been degraded. Vegetation in the outer portion of the buffer is dominated by invasive and/or pioneer species including Himalayan blackberry, Scotch broom and red alder. The low qualit;�of lhis vegetation limits the value of habitat, and the prolective and shading (unclions provided tu ihe wetland and stream by the bu(fer. The sparse vegetalion in the outer edge of the buifer does not impede overland ilow /
