Ponderosa Homes - Lehman/Selway Property - Environmental Checklist c) Uses allowed in residential development are not associated with the substantial use, storage, or transportation of hazardous substances. These substances would not pose a risk to any existing or proposed schools proximate to this project. The site is not located within 'l'.-mi1e of any exist- ing schools. Therefore, this would be categorized as no-impact. d) The site was analyzed6 for the potential presence of residual pesticides and pesticide-related met- als resulting from the former orchard. Eight soil samples were collected from random locations on the site and one sample was collected from inside an existing structure for laboratory analysis. Residual pesticides and metals were detected at very low levels less than the Preliminary Reme- diation Goals (PRG) established by the United States Environmental Protection Agency (USEPA) and the Ca1ifomia Human Health Screening Levels (CHHSLs) for residential sites. The site is not included on the list of hazardous materials sites compiled pursuant to Government Code 65962.5 (Cortese List). Therefore, this would be categorized as less-than-significant- impact. e-f) The site is located approximately five miles from the Livermore Municipal Airport and is not likely to result in a safety hazard for future residents of this development. The project will be conditioned to provide a disclosure to buyers related to the Livermore Municipal Airport activi- ties. Therefore, this would be as less-than-significant-impact. c) The proposed project will not result in interference with an emergency plan or evacuation plan. Therefore, this would be categorized as less-than-significant-impact. d) Wildlands do not exist within or adjacent to the subject site. Therefore, this would be catego- rized as a less-than-significant-impact. 8. HYDROLOGY ANDWATEROUALITY Environmental Setting The subject property is a relative flat site sloping down from Cameron A venue to its north property line. At the request of the Palmer Drive and Diablo Court neighbors, the proposed lots adjoining the lots fac- ing Palmer Drive and Diablo Court will have their building pads graded at or lower than the grades of the adjoining lots, while still ensuring positive drainage of the lots conforming to City standards. At its closest point, the Zone 7 chain-of-lakes - former Kaiser gravel quarry - is located approximately 500 feet from the project site. The National Pollutant Discharge Elimination System (NPDES) was established in the Clean Water Act to regulate municipal and industrial discharges to surface waters of the U.S. Non-point sourced diffuse and originate over a wide area rather than from a definable point. Two types of non-point source dis- charges are controlled by the NPDES program; discharges caused by general construction activities and general quality of storm water in municipal stormwater systems. Standards of Significance For purposes of this environmental document, an impact is considered significant if the proposed project would: PUD-50 and PTR-5572 Page 20 of 36 June 7, 2006
