Introduction of Invasive Plants <br />Potential Impact: The Project could introduce, through its landscaping, <br />invasive, non - native plant species which would adversely impact native vegetation and <br />special- status species which depend on native vegetation, particularly on adjacent <br />Middle Bair Island (Impact 8 -10). <br />Mitigation: Invasive, non - native plant species should not be allowed in <br />Project landscaping plans (Mitigation 8 -10). <br />Findings: Mitigation 8 -10 is feasible and would reduce the Project's effect <br />on native vegetation and special status species which depend on that vegetation, <br />otherwise potentially environmentally significant, to a level of insignificance. <br />VI. HYDROLOGY AND WATER QUALITY <br />A. Erosion and Sedimentation <br />Potential Impact: Project filling, grading and removal of vegetation would <br />disturb watershed lands and expose bare soil to erosion, with the potential for <br />downstream sedimentation of marinas and Redwood Creek, particularly during Project <br />construction (Impact 9 -1). <br />Mitigation: The Project would be required to obtain a National Pollution <br />Discharge Elimination System permit, based among other things on a Stormwater <br />Pollution Prevention Plan containing Best Management Practices, approved by the <br />State Water Resources Quality Control Board. The Plan would control erosion control, <br />stormwater treatment and other measures affecting water quality during and following <br />construction (Mitigation 9 -1). <br />Findings: Obtaining the NPDES permit and implementation of the <br />SWPPP and other permit requirements would reduce the potential watershed <br />disturbance, erosion and sedimentation impacts, otherwise potentially environmentally <br />significant, to a level of insignificance. If the permit is not obtained and implementation <br />measures identified, the Project would not go forward. <br />B. Increased Stormwater Contaminants <br />Potential Impact: Project building and marina development and <br />landscaping would increase stormwater contamination by heavy metals, oil and grease <br />1289 \02 \179278.2 24 <br />Atty /Reno /Reso.1470 14590 <br />060804 Muff # 304 Bin 26 <br />
