3 Water Management in CA has Undergone Several Eras of Change Source: Managing California s Water, E. Hanak et al. (2011) 3

4 Dam Construction Increased Rapidly During California s Hydraulic Era Source: Managing California s Water, E. Hanak et al. (2011) 4

5 California relies mostly on levees, flood bypasses, and reservoirs for flood protection Source: Managing California s Water, E. Hanak et al. (2011) 5

6 Significance of Flood Management More than 7 million people and $580 billion in assets are exposed to flood hazards (CA Water Action Plan) Jones Tract Levee Failure on June 4, 2004 Sacramento, California s capital, has one of the lowest levels of flood protection of any major cities in the nation (CA Water Plan) 6

14 The Challenge: Regulatory Framework and Needs Outpacing Infrastructure Reinvestment & Agency Modernization 1917 Local Leadership Era 2017 Partnerships and Sustainable Funding Protect agriculture Need Flood control for urban areas and agriculture, plus water supply, ecosystem, recreation Predominantly rural agriculture Land Use Widely varied: urban centers, industry, small communities, rural agriculture, public space infrastructure Locally available materials and practices, trial and error, as needed Design and Construction Standards Engineered structures with design life, advanced geotechnical practices and materials No reservoirs, scouring flows Storage and Flows Many reservoirs, coordinated operations, regulated flows for multiple objectives 14

15 Assessing Our Infrastructure Solutions to Raise the Grades Investment o o o Dedicated / Consistent Funding Use Programs to Fund Specific Categories of Deficient Infrastructure Identify True Costs Leadership & Planning o o o o Require life cycle cost analysis Invest in maintenance Prioritize funding Streamline Permitting Process Preparing for the Future o o Promote community resilience (local capacity) Improve land use planning 15

16 Governor s Water Action Plan (2014) A 5-Year Plan to Meet 3 Broad Goals o Reliability -- more reliable water supplies for our farms & communities o Restoration restoring important wildlife habitat & species o Resilience -- more resilient, sustainably managed water systems & environment (supply, quality, flood protection & ecosystems) 16

17 Governor s Water Action Plan A Diverse Water Portfolio of 10 Priority Actions 1. Make conservation a California way of life 2. Increase regional self-reliance and integrated water management across all levels of government 3. Achieve the co-equal goals for the Delta 4. Protect and restore important ecosystems 5. Manage and prepare for dry periods 6. Expand water storage capacity and improve groundwater management 7. Provide safe water for all communities 8. Increase flood protection 9. Increase operational and regulatory efficiency 10. Identify sustainable and integrated financing opportunities 17

19 Central Valley Flood Protection Plan (CVFPP) Adopted historic CVFPP in July 2012 Oversee the implementation of the CVFPP: Assure Board resolution commitments Facilitate projects moving forward based on SSIA Monitor plan implementation benchmarks & communicate to the public Work with DWR to communicate data & tools to public agencies Anticipate to adopt in 2017 the CVFPP update along with the Conservation Strategy and Financing Plan. 19
