12/17/2007 I. General Outdoor Liahtina Impacts on Bioloaical Resources Potential Impact 8-9: The project would result in additional lighting at a close distance to sensitive wetland habitats. Outdoor lighting from the proposed project may adversely affect nocturnal, roosting, and nesting birds, and disrupt natural diurnal rhythms of a wide range of animals and plants. These possible effects represent a potentially significant impact. Mitigation 8-9: Applicant shall implement Mitigation 8-8. Findings: Implementation of Mitigation 8-8 is feasible and would reduce this potential impact to a less-than-significant level. J. Introduction of Invasive. Non-Native Plants Potential Impact 8-10: Since the project site is near the Bair Island National Wildlife Refuge, a federally managed wildlife reserve, invasive non-native plant species could have an adverse effect on native vegetation and special-status wildlife in the area. Special- status wildlife species known from the area, such as California clapper rail and salt marsh harvest mouse, are dependent on native salt marsh vegetation and adjacent upland areas. Displacement of native vegetation by invasive non-native species would adversely impact habitat for these and other special-status wildlife species. In a preliminary landscape plan supplied by the project architect, the project proposes to landscape the site with non-native plants that have the potential to vigorously invade and displace native plants. Use of these plants in landscaping would therefore present a potentially significant impact. Mitigation 8-10: Eliminating the invasive, non-native species from the landscape plan would reduce this identified potential impact of using non-native species to a less-than-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 potential impact of using invasive, non-native species to a less-than-significant level. VI. HYDROLOGY AND WATER QUALITY A. Temporary Soil Erosion Increase and Sedimentation Impacts Durina Proiect Construction Potential Impact 9-1: Project filling, grading, and removal of vegetative cover would expose large areas of bared soil surface to erosion with the potential for attendant downstream sedimentation in both the on-site marinas and Redwood Creek. This is considered a potentially significant impact. Mitigation 9-1: In accordance with National Pollution Discharge Elimination System (NPDES) regulations, require the project applicant to file a Notice of Intent with the State Water Resources Control Board (SWRCB), Division of Water Quality. The filing shall include a description of erosion control and stormwater treatment measures to be implemented during (including Start at the Source measures) and following project construction, as well as a schedule for monitoring of performance. These measures are referred to as Best Management Atty/Reso/Reso.1772 121707 23 14829 Muff# 613
