The Mukilleo School District has commentr ; 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 Pub�ic Services and Utilities Policies) 4. Wetlands (SEPA Earth, !and, Plants and Water Policies) I. Site Description • 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 Welland is a riparian wetland associated with the on- site tributary of Swamp Creek. This Category Iil Strearr, anters the property on the west side and flows southeasterly, draining out at a culvert running under 112�h Street on the south side of the site. The Category III Stream is an upper tributary of Swamp Creek. This stream is naturally intermittent during years of normai rainfall and this upper tributary is not used by salmonids due to a downstream blockage. Category II Wetlands in the City of Everett are protecled by 75-foot buffers. Calegory III Streams in the Cily of Everett are protected by 25-foot buffers. II. Functions and Values Assessment • Stormwater StoragelFloodflow Attenuation/Water Qualily 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 welland area. This serves to slow lhe flow of the stream and reduce peak flows downstream. During periods of low precipitation, water flows from the wetland to the stream, helping to maintain base glows. This wetland also improves water quality. As water slows and passes through the wetland, lhe lower velocity and the dense vegetation serve to remove sediment and pollutants. The lack of dense vegetation in this wetland minimally limits these functions. Overall, this wetland provides good values for these functions. • Wildlife Habitat Due to the size of the wetland, the density and structure of?he vegetation, and the location in an urban area, this wetland provides good habitat for wildlife. Habitat values in this area are limited by the proximity to major thoroughfares and development. Due to the urban location, the most likely animals to utilize this wetland are birds amphibians and small mammals. As this region becomes more developed, urban wetlands such as this will increasingly be relied upon as valuable natural areas. • Welland and Stream Buffer Due to the past clearing, portions of the sile have been degraded. Vegetation in the ouler portion oF the buffer is dominated by invasive and/or pioneer species including Himalayan blackberry, Scotch broom and red alder. The low quality of this vegetation limits the value of habitat, and the protective and shading functions provided to the wetland and stream by the buffer. The sparse vegetalion in the outer edge of the buffer does not impede overland flow or erosion. The lack of dense vegetalion does little to prevent human intrusion into the stream and wetland. This buffer provides moderate levels of functions and values and provides limited protection or shading to the wetland and stream. III. Development Impacts "((� I/612006
