Materials would be collected from the existing stream <br />corridor and the hiil slopes west of the creek, and an off-site donor area. The balance of ttie <br />plant materials would be purchased at a nursery. <br />The plant species proposed for each of the treatment shown in Figures 3 and 4 are listed <br />in Table 2. Species were selected based on their suiWbility for inclusion in bioengineering <br />solutions, environmental needs (soils, moisture, exposure), their value for wildlife, ancf their <br />availability. <br />COMPARISON OF PRE- AND POST CONDITIONS <br />STREAM CHANNEL <br />� <br />p� The proposed restoration project would convert a virtually barren site to a dense corridor <br />of natural vegeWtion, which wuuld shade the stream and provide wildlife habitat and a <br />� migraHon corridor for birds and small mammals. <br />�y Large three-sided, box-culverts, or similar structnre, would span the stream to provide <br />�� access from Hardeson Road to the psoposed development project (Figure 51. Two crossings, <br />each 60 feet wide, are planned at each end ofthe project. <br />6� <br />ix <br />ey <br />{6 <br />VA <br />� <br />WETLANDS <br />Wetlands are likely to develep within the flatter portions of the stream corridor, <br />particularly the corridor shown in Figure 3. Overall, the new corridor would comptise an <br />area of about 1.1 acres lhat would be vegetated primarily with willow and alder. A portion <br />of that area may evolve into wetland depending upon the hydrology. <br />The restoration project would augment low stream Flows. Specifically, the restored <br />stream would encourage infiltration and should delay delivery of water to downstream areas. <br />73 <br />° � <br />t <br />M <br />'��,os�tqii��e;, <br />
