Item No. 1 PC: 11-5-92 SU-91-15 Page 25 Statement of Fact: This impact will be reduced by the formation of a homeowners'association that will be established to preserve the depth, stability,water quality, and aesthetics of the lake. The maintenance of the lake is required to comply with the mitigation measures identified in the EIR, which includes the following: i • State approved algicides and herbicides will be used to maintain water quality. • No lake discharge into Bear Creek will occur during, or shortly thereafter, application of herbicides and algicides. A closeable, leak-proof gate will be provided to ensure that no I water is discharged into Bear Creek during herbicide or algicide use. a • Lake water will be kept at seven feet or above to control rooted aquatic growth. Groundwater pumping from the existing shallow non-potable agricultural well will be used to augment the lake during the summer months. a • Nitrogen fertilizers should not be applied around the lake edge. • Discharge into the lake will be limited to stormwater, and erosion of the banks will be controlled by bulkheads and landscaping. • Taking of fish from the lake for human consumption should not be permitted. • Boat lengths should be limited, and power boats, other than those driven by electric motors, should be prohibited. F.3. Potentially Significant Impact: Portions of the site may be subiect to flooding in relation to Bear Creek. Finding: Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the Final EIR. These mitigation measures are listed below. Statement of Fact: This impact will be reduced by the requirement that an additional study be conducted to determine whether any portion of the development is subject to the 100-year flood. The Flood Control District's Interim Flood Hazard Reduction Policy also applies to the project (Development Title Section 9-1605.14).
