Department of Water Resources Delta Levees Program Presentation for Delta Stewardship Council

Delta Levees Program Program Goal To reduce the risk to land use and associated economic activities, water supply, infrastructure, and ecosystem from catastrophic breaching of Delta levees by building all Delta levees to the Bulletin Standard. Major Components 1. Delta Levees Maintenance Subventions Program 2. Delta Levees Special Flood Control Projects

Historical Perspective Subventions Program Way Bill (1973) Water Code §§ – (SB ) CVFPB Approves the Plan State Share of about $158 million in flood control and habitat projects  1973 – 1987 ($10 M or 39% of total project cost)  1988 – 2006 ($100 M or 53% of total project cost)  2007 – 2009 ($30 M or 75% of total project cost)  2009 – 2010 ($18 M allocated – work in progress) Provides technical and financial supports to local agencies Funding Sources  General Fund  Proposition 13, 50, 204, 84, & 1E

Historical Perspective Special Projects Water Code §§ – (SB ) DWR Executive Approves the Plan State Share of about $270 million in flood control and habitat projects  1988 – 2007 ($125 M – Eight Western Delta Islands)  2008 – 2009 ($30 M – In accordance with the Guidelines/PSP)  2009 – 2010 ($115 M - In accordance with the Guidelines/PSP) Provides technical and financial supports to local agencies Funding Sources  General Fund  Proposition 13, 50, 204, 84, & 1E

January 09 DWR Released Interim Guidelines for Delta Levees Special Projects February 10 Special Projects Near-Term Guidelines and Levee Improvement PSP Released to Public.

6 DRMS - Phase 1 Purpose 1. Analyze Risks to the State Resulting From Failure of Delta Levees Due to floods, earthquakes, subsidence, dry weather failures, and climate change 2.Determine Consequences to Economy & Ecosystem Goals 1.Identification of Risks to Statewide Interests 2.Analysis of Impacts on Delta and State

7 DRMS - Phase 2 Purpose Develop Risk Reduction Strategies for Long-Term Management of the Delta Methodology 1.Develop a menu of risk reduction measures that could reduce risk – “Building Blocks” 2.Package the measures into different combinations – “Trial Scenarios” 3.Use Risk Model to evaluate potential risk reductions 4.Evaluate benefits and costs of these risk reduction measures
