Ponderosa Homes at 6900 Valley Trails Drive <br /> Initial Study and Negative Declaration <br /> a) Violate any water quality standards or waste X <br /> discharge requirements? <br /> b) Substantially deplete groundwater supplies or X <br /> interfere substantially with groundwater recharge <br /> such that there would be a net deficit in aquifer <br /> volume or a lowering of the local groundwater table <br /> level (e.g., the production rate of pre-existing nearby <br /> wells would drop to a level which would not support <br /> existing land uses or planned uses for which permits <br /> have been granted)? <br /> c) Substantially alter the existing drainage pattern of the X <br /> site or area, including through the alteration of the <br /> course of a stream or river, in a manner, which would <br /> result in substantial erosion or siltation on- or off-site? <br /> d) Substantially alter the existing drainage pattern of the X <br /> site or area, including through the alteration of the <br /> course of a stream or river, or substantially increase <br /> the rate or amount of surface runoff in a manner, <br /> which would result in flooding on-or off-site? <br /> e) Create or contribute runoff water which would X <br /> exceed the capacity of existing or planned <br /> stormwater drainage systems or provide substantial <br /> additional sources of polluted runoff? <br /> f) Otherwise substantially degrade water quality? X <br /> g) Place housing within a 100-year flood hazard area as X <br /> mapped on a federal Flood Hazard Boundary or <br /> Flood Insurance Rate Map or other flood hazard <br /> delineation map? <br /> h) Place within a 100-year flood hazard area structures, X <br /> which would impede or redirect flood flows? <br /> i) Expose people or structures to a significant risk of loss, X <br /> injury or death involving flooding, including flooding <br /> as a result of the failure of a levee or dam? <br /> j) Inundation by seiche, tsunami, or mudflow? X <br /> ENVIRONMENTAL SETTING <br /> The project site does not contain creeks, wetlands, or other water bodies. The <br /> project site is located in Zone X, outside the 100-year flood zone. The project, <br /> including structures, roads, sidewalks, and driveways would result in 203,964 square <br /> feet of additional impervious area compared with existing conditions. <br /> 28 <br />
