An e�dsting driveway paralleling t6e east side of Silver Lake Creek will be removed and benches created for planting shrubs and vees. Figure 4 depicts the pro6le change proposed to expand the ripazian/wetland habitat along the creek. 'Ibe water supply for the wetland areas will be from surface runof� Silver Ialce Creek, and groundwater. Method o[ Mitigation Mitigadon will include the following components: • identification of specific site topography and groundwater and surface water elevations; • excavation of streamside bench areas; and • planting of trees, shrubs, and emergent vegetatiou. Table 1 presenu the species of vegetadon proposed for placuing, and Figure 5 presents a schematic vegetadon plan for creation and enhancemen� Plant species selected for planting aze those rernmmended by the Was6wgton State Department of Wildlife for riparian, open water, and shallow water rnnditions (Washington State Department of Wildlife 1984). The proposed mitigadon plan will provide the followir,g benefits; • improve flood storage of Silver Lake Creek by increasing the floodway width; • improve t6e dive�sity and width of ripazian habitat along �ilver Lake Creek; and • improve the habitat value of the existing pond and adjacent wedand area by providing additiontil wetland plant vegetadon. 77me L(ne The midgation azea will be developed during earth-work (grading) activities for the remainder of the site. The approximate schedule will be as follows: • September 1988 - identification of site-specific topography and surface warer condidons; 10
