7C Page 44 I. General Ou#doar Liqhtinp impacts on Bioloaical Resources P�t�retia! lrr�pact 8-9: The project weufd result in additianal ligh#ing at a close distance to sensitive wetland habita#s. Outdoor lighting from the proposed project may adversely affect nocturnal, roosting, and nesting birds, and disrupt natural diurnal rhythms of a wide range o# animals and plants. These possible effects represen# a pofentially signifrcant impact. Mitigation 8-9: Applicant sha{I implement Mitigation 8-8. Findings: Implementa#ion of Mitigafion 8-8 is feasible and would reduce this potentia( impact to a less-than-signi�cant level. J. introduction of Invasive Non-Native Plants Potential Impact 8-10: Since the project site is near the Bair Isiand NationaE Wifdlife Refuge, a federally managed wildfife reserve, invasive non-native plant species could have an adverse effect an na#ive vegeta#ion and specia!-status wildlife in #he area. Special- status wildlife species known from the area, such as California clapper rail and salt marsh harvesf mouse, are dependent on native salt marsh vegetation and adjacent up(and areas. Dispiacement of native vegetation by invasive non-native species would adversely impact habitat far these and other special-status wildlife species. (n a preliminary fandscape plan supplied by the project architect, the projECt proposes to landscape the site with non-native plants that have the patential to vigorously invade and displace native plants. Use of these plants in landscaping would therefore present a pofentrally signi�cant impact. Mitigation 8-10: Efiminating the invasive, non-native species from the landscape plan would reduce this identified patential impact of using nan-native species to a less-fhan-significant level. Additions/substitutions to the landscape plan plant list shall be subject to City approval. Findings: Mitigation 8-10 is feasible and would reduce this identified potentiai impact of using invasive, nan-nati��e species to a tess-than-signifcant Ievel. VI. HYDR�LOGY AND WATER QUALITY A. Temporarv Soil Erosion Increase anci Sedimentation lmpacts Durinq Proiect Construction Potentiat Impact 9-1: Project �Iling, grading, and removal of vegetative cover would expose Earge areas of bared soil surFace to erosion with the potential for attendan# downstream sedimentation in both the an-site marinas and Redwood Creek. This is cons9dered a pofentially significant impacf. Mitigation 9-1: In accordance with National Pol(ution Discharge Eiimination System (NPDES) regulations, require the project applicant #o file a Notice of Int�nt with the State Water Resources Control Baard (SWRCB), Division oi Water Quality. The filing shall inciude a deseripfion of erosion control and stormwater treatment measures ta be implemented during (inciuding Start at the Source measures) and following project construction, as well as a schedule for monitoring af performance. These measures are referred to as Bes# Management A#ry/ResolReso.1772 23 121307
