wedands will not significandy affecc the hydrolo� (stortn water storage) of the site because the hydrologic function 6a5 already been altered by past 6ll activities. The proposed 6ll activity will, however, eliminate the hydrologic functions that now e�ast in the 0.24 acres of un£illed wedand. Wildlife value of the filled wetland is very limited because of We sparse vegetatian and Iack of suitable soil. The unfilled wedand rnntains some standing water and supports vegetation suitable for waterfowl and xed-eating sonsbirds. '1!u wedand azea at the southem end of the site will aot be signi6candy disturbed by the projecK. A small corner of the wedand (0.03 acres), consisttng of hydric soils and mowed grasses, will be Iost by construccion of a four-plex uniG This 0.03-acre Hgure is included in the 0.24-acre total listed above. Remaining wedand areas will be either maintained or enhanced. PROPOSED MITTCATION Type and Location of MIt(gation Wedand loss will be mitigated by: 1) creating 0.25 acres of wetlands from existing uplands; 2) enhancing 0.11 acres of existing wetland; and 3) enhancing .03 acces of ripurian habitat along Silver Lake Creek. Figure 3 shows the proposed plan Wetlend Creation Wedands will be created on the wet properry boundary and just north of the e�asting pond at the southwest oomer of the property (Figure 3). Exisdng upland areas will be excavated to elevations comparable with the pond and Silver Lake Creek channel. The new wedand area will be lined wit6 peat and organic soils excavated from the wedand area to be filled Habitat to be created will include open water and stands of emergent and shrub vegetadon (e.g., burreed, spiraea, etc.). Wetlend Enhsncement Wedand en6ancement will be carried out on the edge of the ezisdng pond at the southwest comer of the property along Silver Lake Creek (0.03 acres) and on the northwest corner of the properry (0.01 aaes). This will include plandng of prefeaed wildlife wedand and riparian species such as cottonwood, red osier, dogwood, crabapple, willow, and wild rose.
