proposed amendments will assure that potential impacts to hazards and hazardous materials <br />are not exacerbated. There would be no new or more severe significant impacts to hazards and <br />hazardous materials. <br />5.6 HYDROLOGY AND WATER QUALITY <br />This section analyzes the effects to hydrology and water quality from implementing the <br />proposed zoning code regulations. <br />Would the project: <br />a. Violate any water quality standards or waste discharge requirements? <br />b. Substantially deplete groundwater supplies or interfere substantially with groundwater <br />recharge such that there would be a net deficit in aquifer volume or a lowering of the <br />local groundwater table level (e.g., the production rate of pre-existing nearby wells <br />would drop to a level that would not support existing land uses or planned uses for <br />which permits have been granted)? <br />c. Substantially alter the existing drainage pattern of the site or area, including through the <br />alteration of the course of stream or river, in a manner that would result in substantial <br />erosion or siltation on or off site? <br />d. Substantially alter the existing drainage pattern of the site or area, including through the <br />alteration of the course of a stream or river, or substantially increase the rate or amount <br />of surface runoff in a manner that would result in flooding on or off site? <br />e. Create or contribute runoff water which would exceed the capacity of existing or planned <br />stormwater drainage systems or provide substantial additional sources of polluted <br />runoff? <br />g. Otherwise substantially degrade water quality? <br />h. Place housing within a 100-year flood hazard area as mapped on a federal Flood <br />Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? <br />i. Place within a 100-year flood hazard area structures, which would impede or redirect <br />flood flows? <br />j. Expose people or structures to a significant risk of loss, injury, or death involving <br />flooding, including flooding as a result of the failure of a levee or dam? <br />k. Expose people or structures to a significant risk of loss, injury, or death involving <br />inundation by seiche, tsunami, or mudflow? <br />TZC EIR Conclusions <br />• The Transit Zoning Code (SD 84A and SD 84B) area is not located within a 100-year <br />flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance <br />Rate Map or other flood hazard delineation map, and is not within the 100-year or 500- <br />year flood hazard area. (DEIR Section 4.6.3: Effects Found to Have No Impact) <br />• The Transit Zoning Code (SD 84A and SD 84B) area is not within the 100-year flood <br />hazard area, (DEIR Section 4.6.3: Effects Found to Have No Impact) <br />• The Transit Zoning Code (SD 84A and SD 84B) area is not located in the flood <br />inundation area of the Prado Dam or the Santiago Dam. (DEIR Section 4.6.3: Effects <br />Found to Have No Impact) <br />• The proposed Transit Zoning Code (SD 84A and SD 84B) would not expose people to a <br />significant risk of loss, injury, or death involving inundation by a seiche, tsunami, or <br />mudflow because the project site is not located near a coastal area, large water body, or <br />January 2025 33 Environmental Analysis <br />
