Meadowlark Development - Austin Property - Environmental Checklist c) Uses allowed in residential development arc not associated with the substantial usc, storage, or transportation of hazardous substances. These substances would not pose a risk to any existing or proposed schools proximatc to this project. The site is not located within \4-mile of any exist- ing schools, Therefore, this would be categorized as no-impact. d) The site is uscd for cattle grazing and, for this rcason was not analyzed for the potential presence of residual pesticides and pesticide-relatcd metals resulting from the orchard or other types of ag- ricultural activities. Therefore, this would bc categorized as less-than-signijicant-impact. e-f) The site is located approximately five miles from the Livcrmore Municipal Airport and is not likely to result in a safety hazard for future residents of this development. Therefore, this would be as less-than-signijicant-impact. g) The proposed project will not result in interference with an emergency plan or evacuation plan, Thcrefore, this would be categorized as less-than-signijicant-impact. h) The site is surrounding by vacant hillsides, which will remain vacant. A Wildland Fire Man- agement Plan (WFMP) will be prepared with the tentative subdivision map for review by the Fire Marshall and rcview/approval by the Planning Commission, Measures identified in the WFMP will be incorporated into the City's management/maintenance plan of the open space area.

HYDROLOGY ANDWATEROUALITY Environmental Setting The subject property is characterized by moderate to steep terrain. Going east to west, across the pro- posed dcvelopment area, the site slopes upward from Old Foothill Road from an elevation of 380 feet to an elevation of 470 feet. From its absolute lowest to highest points, the site slopcs upward from 360 feet to 520 feet. A series of ephemeral creeks/swales drain the site to the Arroyo De La Laguna, The United States Army Corps of Engineers has jurisdiction on the central stream, which will flow through the cen- tral area of the proposed development. The area westerly of the site from its northwest boundary line is characterized by steeply sloped, tree-covcred terrain, The National Pollutant Discharge Elimination System (NPDES) was established in the Clean Watcr Act to rcgulate municipal and industrial discharges to surface waters of the U,S. Non-point sourced diffuse and originate over a widc 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.
