Recommendations Find that adopting a resolution in support of the California WaterFix and the California Eco Restore is exempt from the California Environmental Quality Act per Guidelines Section 15061 (b)(3); and Adopt a Resolution in support of the California WaterFix and California Eco Restore 2
Sacramento -San Joaquin Delta Sacramento & San Joaquin Rivers form the Sacramento- San Joaquin Delta ( Delta ) > Wetland consisting of marshes, levees, islands, and waterways > Home to more than 500 plants & wildlife including the endangered delta smelt > 1,150 square miles in area > 1,100 miles of levees & 700 miles of waterways > 4.9 million acre-feet ( MAF ) per year in water supplies to 25 million people & 3 million acres of agricultural land. 3
Delta Major Hub of Water Exports South Delta diversion at the Clifton Court Forebay > Two large pumping plants > Harvey Banks for the SWP > Bill Jones for the CVP 1
Delta Major Hub of Water Exports South Delta diversion at the Clifton Court Forebay > Two large pumping plants > Harvey Banks for the SWP > Bill Jones for the CVP Central Valley Project ( CVP ) > U.S. Bureau of Reclamation ( USBR ) > Constructed in the 1940s > 2.2 MAF/year for central California agricultural & farm land State Water Project ( SWP ) > California Department of Water Resources ( DWR ) > Constructed in the 1960s > 2.7 MAF/year for central & southern California municipal and institutional > Conveyed via California Aqueduct 2
Delta Issues Reverse Flows Pumps redirect river flows > Entrain and trap fish (endangered Delta Smelt) > Introduce higher salinity 5
Delta Issues Levee Vulnerability > Large seismic event and subsidence may breach levees > Re-direct flows and impact downstream users > Introduce chemicals & increased turbidity > Costly repairs Supply Reliability > Global warming & rising sea levels 6
Water Delivery With and Without California WaterFix 6.00 5.00 Average Conveyance (1) SWP & CVP Contractors Metropolitan Water District 4.70 5.00 (4) Volume (MAF) 4.00 3.00 2.00 1.00 1.20 3.70 (3) 0.84 360 TAF Reduction (30%) 1.21 0.00 Existing Conditions Future without CA WaterFix Future with CA WaterFix (2) (2) (1) All deliveries assumed with 2025 climate change impacts. (2) Future scenarios analyzed under a range of outflow requirements & operating criteria. (3) Future without CA WaterFix ranged from 3.5 to 3.9 MAF. (4) Future with CA WaterFix ranged from 4.7 to 5.3 MAF.
California WaterFix 3 intakes and 34 miles north of Clifton Court Forebay > Each rated at 3,000 CFS Main Tunnels > Two tunnels, 40-foot diameter and 30-miles in length > Up to 150 feet below ground surface Schedule > Construction 13 years > Operational by mid-2030s 8
California WaterFix Benefits Dual conveyance > Provides operational flexibility > Allows for operations in a dynamic fishery environment > Diversion of excess flood flows for dry-year storage & emergencies Reduce risks for climate change > North intakes are at a higher elevation Improved flow patterns in the Delta > Reduced diversion in the south Delta which lessens reverse flows > Reduce risk of fish entrainment Reduce seismic and subsidence risks > Tunnels are reinforced & below grade Improved water quality > Lower total dissolved solids, salinity & bromide 9
California Eco Restore Restore and protect +30,000 acres of Delta habitat by 2020 > Restore floodplains, tidal habitat, and aquatic and riparian habitat Work in progress: > Restored 1,900 acres of habitat > 3,900 acres are under construction & 23,200 acres under permitting > Restored 1.2 miles of aquatic waterways & planning and permitting 5.5 miles Planning & implementation cost $300 million > Funded primarily by CVP and SWP contractors 10
California WaterFix Cost Capital cost at $16.7 billion (2017 dollars) > Contingency of 36% or $3.7 billion > $401 million in capital mitigation Operation, maintenance, and mitigation cost > $64.4 million in 2033 (2017 dollars) > Facilities operational by 2033 SWP contractors cost share at 55% > Negotiating with CVP contractors on cost share Metropolitan Water District ( MWD ) is the largest SWP contractor with 45.8% rights > 5 of 29 SWP contractors will not benefit from California WaterFix > MWD s cost share 47.1%

Risks of Not Moving Forward with California WaterFix Increasing regulatory constraints > Impacts to water operations result in reduced diversions > In ability to capture storm flows for drought and emergency supplies > Threatened fish species requiring higher outflows and decline in water supply Threats from earthquakes and subsidence > Levee failures and flooding > Introduce higher turbidity and chemicals > Costly repairs Climate change > Rising sea levels and introducing higher salinity into water supplies 19
Risks of California WaterFix Political Risks > Strong opposition challenging the project Taking of additional water True cost of project & rate impacts Alternatives (conservation, recycled water, desalination, storm water capture) > Potential litigation costs and project delays Construction Overruns > Very large and complex project Rate Impacts > MWD s cost allocation is volumetric based > PWP will always be dependent on MWD imported water 20
Local & Regional Water Supply Pasadena s water supply > Local groundwater & spreading credits 40% > Imports from MWD 60% MWD s imported water supply > SWP water provides 60% Preserving investments made in the SWP > City is 1.2% of MWD s sales > MWD has 45.8% of rights to the SWP water Water Integrated Resources Portfolio > Local resources (groundwater, conservation, recycled water, stormwater) Southern California s water supply > SWP water 30% 21
California WaterFix -Conclusion The threat to the water supply and reliability is greater if no action is taken. California WaterFix supports the 2009 Delta Reform Act co-equal goals of improving the State s water reliability while protecting, enhancing, and restoring the Delta ecosystem. 22
