Flood Managed Aquifer Recharge Study in Santa Clara County Presented by: Samantha Greene, Senior Water Resources Specialist Water Supply Planning & Conservation

Water Supply “Ensure Sustainability” Strategy • “No Regrets” Package of 1. 2. 3. Secure existing supplies and infrastructure Expand conservation and reuse Optimize the system conservation and stormwater capture projects • Includes Flood MAR • Flood MAR “secures” recharge on open lands, expands local stormwater capture and use

• Flood MAR: Using high flows from, or in anticipation of, rainfall or snowmelt, for managed aquifer recharge on agricultural lands, working landscapes, and natural managed lands. • Many components/options: - Site selection - Stormwater collection/routing - Improving water quality - Multiple infiltration methods - Incentives for stakeholders - Tools for accounting DWR (2018)

• UC Water: An alliance of faculty, researchers, and students from multiple UC campuses, seeking Four main UC Water components: innovative solutions to some of • Headwater Management California's most pressing water • Groundwater Resources resource management challenges. • Intelligent Water Systems • Water-Energy Nexus Institutional assessment Mapping suitability for flood MAR Incentives

Water Resources Innovation Partnership • Evaluate options and challenges for a Flood MAR program in Santa Clara County • Technical implementation • Institutional considerations • Incentives for program participation • Develop GIS-based tools to quantify Flood MAR suitability for the Valley Water service area
