4 Environmental Analysis <br /> 4.10 Hydrology/Water Quality <br /> IS-4.19— Water Efficient Landscaping: The County shall encourage water efficient <br /> landscaping and use of native, drought-tolerant plants consistent with the Model <br /> Landscape Ordinance. (RDR) <br /> Goal IS-7: To manage stormwater from existing and future development using methods that <br /> reduce potential flooding, maintain natural water quality, enhance percolation for groundwater <br /> recharge, and provide opportunities for reuse. <br /> IS-7.1—Adequate Stormwater Facilities: The County shall require that stormwater drainage <br /> facilities are properly designed, sited, constructed, and maintained to efficiently capture and <br /> dispose of runoff and minimize impacts to water quality. (RDR) <br /> IS-7.2 — Stormwater Drainage System Standards: The County shall require the minimum <br /> standards for stormwater drainage system improvements provided in Table IS-3 for the <br /> approval of tentative maps and zone reclassifications. (RDR) <br /> Goal NRC-3: To ensure the quality of water for municipal and industrial uses, agriculture, <br /> recreation, and fish and wildlife. <br /> NRC-3.1 — Preserve Groundwater Recharge Areas: The County shall strive to ensure that <br /> substantial groundwater recharge areas are maintained as open space. (PSP) <br /> NRC-3.2— Groundwater Recharge Projects: The County shall encourage the development <br /> of groundwater recharge projects of all scales within the County and cities to increase <br /> groundwater supplies. (PSP) <br /> NRC-3.3 — Multi-Jurisdictional Groundwater Management Evaluation: The County shall <br /> support multi jurisdictional groundwater management that involves adjacent groundwater <br /> basins. (IGC) <br /> NRC-3.4 — Eliminate Pollution: The County shall support efforts to eliminate sources of <br /> pollution and clean up the County's waterways and groundwater. (PSP) <br /> NRC-3.5 — Low Impact Development: The County shall require new development to <br /> minimize or eliminate stormwater quality and hydro-modification impacts through site design, <br /> source controls, runoff reduction measures, best management practices (BMPs), and Low <br /> Impact Development(LID). (RDR) <br /> NRC-3.6— Prohibit Discharge of Sewage Sludge: The County shall prohibit the discharge <br /> of sewage sludge or septage to surface waters or surface water drainage sources, including <br /> wetlands and waterways. (RDR) <br /> NRC-3.7 — Septic Tank Regulation: The County shall enforce its septic tank and onsite <br /> system regulations consistent with Central Valley Regional Water Quality Control Board policy <br /> that recognizes the County as the responsible agency to protect the water quality of surface <br /> water and groundwater. (RDR) <br /> NRC-3.8 — Support Sufficient River Flows: The County support properly timed flows of <br /> sufficient quality in local waterways necessary to sustain healthy fisheries. (PSP) <br /> NRC-3.9 — Require Water Projects to Mitigate Impacts: The County shall require water <br /> projects to incorporate safeguards for fish and wildlife and mitigate erosion and seepage to <br /> adjacent lands. (RDR) <br /> NRC-3.10— Coordination for Waterway Protection: The County shall coordinate with city, <br /> State, and Federal agencies to implement policies regarding protection and enhancement of <br /> waterways and levees.
