Mitigation Measure BIO-13c: Monitoring, passerine avoidance measures; buffer <br />adjustments <br /> <br />Impact BIO -14: Impacts on special-status bat species. <br /> <br />Potentially significant impacts on special-status bat species could result from Project <br />construction activities that require tree removals or pruning of trees that provide suitable roosting <br />habitat for special status bat species or that are occupied by roosting bats. Bats could then <br />abandon their young if impacts were to occur during seasonal periods of activity (about February <br />15 through April 15 and August 15 through October 30). <br /> <br />. Mitigation Measure BID 14a: Bat habitat assessment; pre-construction survey for signs <br />of bat activity <br />. Mitigation Measure BID 14b: Consult with the CDFG; bat exclusion and eviction <br />measures <br /> <br />Impact BIO -15: Temporary and permanent impacts on wetlands and other waters of the <br />U.S. and waters of the State. <br /> <br />Grading, excavation and filling to accommodate the construction of BDPL No.5 and its ancillary <br />facilities would result in permanent and temporary impacts on federally and State jurisdictional <br />waters and wetlands. Permanent impacts would result where pennanent changes in ground <br />surface elevations preclude natural reestablishment of wetlands. For purposes of this impact <br />analysis, it was assumed that the entire area of the right of way and the staging areas would be <br />disturbed by such activities as grading, trenching, stockpiling of earth or supplies, or clearing. <br />This area encompasses approximately 240 acres (97 hectares) of undeveloped land. Permanent <br />conversions from bare ground to paved or permanent structures would be limited to the footprint <br />of the valve vaults, control buildings, and related permanent facilities (e.g., manholes, walkways, <br />fuel tanks). The total footprint of new structures would be approximately 11,605 square feet. <br />Project excavations for pipeline and valve vault construction could also affect wetlands and other <br />waters of the U.S. and waters of the State by causing erosion and sedimentation or the release of <br />contaminants. Draft EIR Table 4.52 presents a summary of permanent and temporary impacts on <br />all wetland categories, as well as riparian areas. <br /> <br />. Mitigation Measure BID 15a: Compensation measures for temporary impacts; <br />preparation of a channel and habitat restoration plan <br />. Mitigation Measure BID i5b: Compensation measures (i.e., purchase of wetland credits, <br />payment of in-Heu-of fees; payment of monies toward specific public or private wetland <br />habitat creation, restoration, or enhancement projects; undertake a wetland creation <br />project on SFPUC lands) for permanent impacts <br />. Mitigation Measure BID 15c: Document location of wetlands to be avoided on contract <br />drawings; install construction fencing; routine monitoring; repair damage; notify <br />..... ~~g~~~~t?l)'.

These habitats and communities include Central Coast riparian scrub and <br />oak woodlands. Because these areas provide valuable habitat and water quality benefits, the <br />permanent loss of these plant communities would be a significant impact. Draft EIR Table 4.5 3 <br />identifies the permanent impacts on riparian habitat and other sensitive natural communities. <br /> <br />14 <br />
