2. SCOPE OF WORK • Qualitatively describe sources of pollution from short-term construction and long-term operation of the project including metals, salts, nutrients, oils, herbicides, and other pollutants associated with urban residential development and street systems. Identify, and to the extent possible quantify any pollutants that may be related to maintenance operations including fertilization, application of herbicides, rodenticides. The Alameda County Runoff Clean Water Program (ACRCWP) has identified a number of commonly used products in residential areas that may be having significant effects on the ecological health of receiving waters. Discuss recent research on these substances and discuss approaches that the ACRCWP is taking to deal with the problem. Relate these approaches to the proposed project. • Identify mitigation to reduce long-term pollutants from entering surface water systems including use of integrated vegetation and pest management methods to reduce pollutant and nutrient sources. The mitigation list will include provisions that could be incorporated into the NPDES SWPPP. The mitigation plan, however, will not constitute a complete SWPPP, unless provided by the applicant. 10. Biological Resources Issues The approach to the biological resources section assumes that the previous Lake Chabot Terrace studies are complete and accurate and that no supplemental surveys are required. In this case, the EIR analysis of the site would rely solely on the studies that have been prepared to date. ESA would verify the accuracy of these documents with a general site reconnaissance. If the surveys conducted to date do not meet current state and federal protocols and regulations or do not cover the entire project area, ESA may need to complete supplemental surveys described as an optional task below. If feasible, due to the less intensive Boulders development proposal, biological impacts could be focused out using the Initial Study and Notice of Preparation. The site has a fairly low profile as sensitive species and wetland habitat due to the extensive grading and quarrying activities that have occurred there. Due to the extensive grading, on -site potential impacts may be limited to off -site biological resources. Habitat for nesting waterfowl and raptors occurs adjacent the site at Lake Chabot. Sensitive resources known or potentially occurring on the property include Alameda whipsnake and Congdon's tarplant. The City and applicant have completed a number of biological studies that relate to these resources. ESA will base the EIR analysis on these documents, evaluate the need for more specific biotic Boulders Residential Development EIR 24 of 37
