Stream Channel. 'Ilie proposed restoration projcct would conven a virtually barren <br />site to a dense corridor of natural vegetation, which would shade the stream and provide <br />�� habitat and a migration corridor for birds and small mammals. <br />M ' <br />Large three-sided, box-culveru would span the stream to provide access from <br />�' Hardeson Road to the proposed development project (Figure 6). Seven crossings, each 60 <br />�a feet wide, are planned for the entire developed project, resulting in ��overing of about 360 <br />feet of stream channel (one crossing dces not span open creek channel). The existing creek <br />' currently flows through several culverts that total more than S50 feet of channeL Ta.,le 3 <br />� summarizes existing and post-project stream length and distance covered by culveru. In <br />summary, the total length of open stream channel after project completion would be 60 feet <br />' less than at present. The comparison in Table 3 likely underestimates the benefits of the <br />r' project because those section covered by cuiveru in the post-project condition (with natural <br />substrates and high level of light penetration) would have greater biological value than the <br />sections that are presenUy in culverts. <br />w <br />14 <br />� <br />-4 <br />E <br />
