Ingram, City Manager FROM: Steve Myrter, P.E., Director of Public Works SUBJECT: SUPPORT FOR CALIFORNIA WATERFIX AND ECORESTORE SUMMARY OF REQUEST: That the City Council adopt Resolution No. 6758 supporting the California WaterFix and California EcoRestore. BACKGROUND AND ANALYSIS: In partnership with the Municipal Water District of Orange County (MWDOC), the City of Seal Beach participated in the recent Orange County Water Reliability Study (Study) evaluating scenarios and projects that enhance or sustain water supplies to the region. Modeling shows the California WaterFix, as currently proposed, represents the most cost - effective, large -scale reliability solution to improving Orange County's water supply reliability over the next 25 years. The supply analyses in the Study assumed that the California WaterFix results in "recovery" (i.e., prevents the future loss) of historical supplies in the amount of 440,000 acre -feet per year on average. As a critical source of water supply, the California Bay Delta provides approximately 30 percent of Southern California's water supply annually through the State Water Project (SWP), a water management program designed to provide water from northern California to the drier southern California region. Originally built in the 1950's, the SWP contains over 20 dams, numerous pumping stations and power plants and a network of more than 700 miles of aqueducts, canals, pipelines and tunnels. One of the oldest sections of this system, with many levees at risk of disaster should earthquakes, floods or sea level rise occur, is the San Joaquin Delta. Its aging infrastructure has threatened future water supply reliability and sustainability. The California WaterFix involves construction and design of the three new water intakes north of the Delta and the two, 32 -mile, 40 -foot diameter, 9,000 cubic feet per second (cfs) underground tunnels that will provide Agenda Item M operational pumping flexibility and protect against water supply disruption. The new, twin tunnels would be built under the delta, thus bypassing many risks associated with above ground water transportation systems (levee failure, earthquake, salt water intrusion due to sea water rise and flooding). In addition to water management and quality benefits, the companion initiative to the California WaterFix is the EcoRestore, which seeks to achieve the State's co- equal goal of habitat restoration and reliability of supplies. EcoRestore is initially charged with 30,000 acres of restoration efforts under an accelerated effort by 2020 to improved habitat conditions for fisheries migration, restore tidal and non - tidal wetland habitat for native wildlife, and improve connectivity among existing grassland and other natural habitats. Success in the Delta continues to rely on the implementation of the California WaterFix and EcoRestore to achieve the co -equal goals. The ecological health of the Delta and fish species are fundamentally linked to the reasonable use and export of water supplies. Although total restoration of the Delta to the historical past is not possible, there can be significant improvements in how best to approach the management of the Delta's combined water and land resources in a manner that will realistically achieve improvements in both water supply reliability and ecosystem protection of the Delta's endangered or threatened aquatic species. However, much remains to be determined, especially with respect to the financing, regulatory certainty and operating criteria for the project. The California WaterFix, which is in the final stages of permitting and environmental approval (EIR /EIS and Record of Decision) is requesting support from all water agencies for this proposal. Based on these proposed improvements in system conveyance and habitat restoration, staff recommends adopting a support position for the California WaterFix and California EcoRestore. ENVIRONMENTAL IMPACT: There is no environmental impact related to this item. LEGAL ANALYSIS: The City Attorney has reviewed the resolution and approved as to form. FINANCIAL IMPACT: There is no fiscal impact related to this item. The California WaterFix and EcoRestore projects are estimated to cost around $15 Billion with the costs being distributed to member agencies based upon usage (estimated at approximately $5 per month to Orange County water costumers).

Resolution No. 6758 Page 3 "Attachment A" RESOLUTION NUMBER 6758 A RESOLUTION OF THE SEAL BEACH CITY COUNCIL SUPPORTING THE CALIFORNIA WATERFIX AND CALIFORNIA ECORESTORE WHEREAS, the Delta, formed by the confluence of the Sacramento and San Joaquin Rivers as they come together and flow into San Francisco Bay, is a major water hub for California's water supply system for the majority of the State, including 30 percent of the supplies for Southern California, and therefore underpins the overall economy of California, which stands equivalent to the 6`h largest country in the world; and, WHEREAS, the Delta historically was a complex and dynamic natural system driven by tidal fluctuations and natural marsh flooding that has been highly altered over the last 100 years, with many of the levees and islands reclaimed from former marshlands for development or farming. The Delta was never intended to be a water conveyance facility. The scientific consensus is that the Delta is not sustainable as it exists today and that changes must be made to stabilize conditions; and, WHEREAS, from a fisheries, farming and water- management perspective, the Delta will continue to decline, at an increasing rate as sea levels rise and continuing subsidence caused by farming result in salinity intrusion, artesian conditions and levee failures, which will become more frequent and more expensive to mitigate or repair as time passes; and, WHEREAS, 25 million residents rely on water from the Delta, and local conservation cannot replace the water the Delta has historically supplied to Southern California even though that amount is only 4 percent of the annual average Delta flows; and, WHEREAS, no practicable and economically efficient way exits to improve existing levees to keep pace with sea level rise or prevent levee collapse during a large earthquake. The consequences to the Bay Delta ecosystem, the water supply and the California economy would be immediate, severe and negative when these events occur; and, WHEREAS, Voters approved the State Water Project (SWP) about 55 years ago, yet it was never completed as envisioned to include an independent conveyance facility that would allow increased capture and storage of water during periods of high flows and would also minimize conflicts with fisheries; and, WHEREAS, as the result of federal court decisions, U.S. Fish & Wildlife Service and National Marine Fisheries Service Biological Opinions, as well as other regulatory constraints to protect native species in the Delta, the SWP has not been able to collect, store, and deliver an estimated volume of 3.6 million acre - feet of water since 2008; and, Resolution Number 6758 WHEREAS, although restoration of the Delta to the conditions of the historical past is not possible, much has been learned through science studies about what is needed to improve the management and utilization of the Delta that can enhance fish, wildlife and water management for the future; and, WHEREAS, Governor Brown's California WaterFix and California EcoRestore proposal provide a framework of how best to approach managing the Delta's combined water and land resources in a manner that will realistically achieve improvements in both water supply reliability and ecosystem protection for the Delta as an evolving place by balancing the many competing demands; and, WHEREAS, the California WaterFix and Eco- Restore proposal will help with water supply reliability by improving essential ecosystem functions so that populations of endangered or threatened aquatic species will be strengthened; and, WHEREAS, the California EcoRestore will pursue more than 30,000 acres of critical Delta restoration over the next five years, including the improvements of habitat conditions for fisheries migration, restoring tidal and non -tidal wetland habitat for native wildlife, and improving connectivity among existing grassland and other natural habitats; and, WHEREAS, the California WaterFix includes construction of three intakes north of the Delta, two 35 -mile tunnels up to 150 feet below the Delta and Clifton Court forebay modifications, all of which will provide operational pumping flexibility and protect against water supply disruption due to sea -level rise, earthquakes and flood events; and, WHEREAS, the three new intakes north of the Delta will improve environmental conditions in the Delta by reducing reverse -flow conditions, minimizing the trapping of migrating fish and reducing diversions during critical fish - migration periods, which will allow more operational flexibility to enhance water deliveries, especially during wet periods; and, WHEREAS, improving the SWP system can increase regional storage reserve levels. These storage reserves are used to protect the region from devastating effects of drought and other emergencies. The California WaterFix will help ensure that Orange County will have sufficient supplies at critical times when we need them; and, WHEREAS, the 2016 Orange County Water Reliability Study revealed a number of important findings with implications for the county's water reliability, including that projected water shortages would be too frequent and overall reliability would not be sustainable by as early as 2030 without new supply and system investments by the Metropolitan Water District of Southern California (MET), its member agencies and Orange County; and, Resolution Number 6758 WHEREAS, Orange County should strongly advocate for the implementation of the California WaterFix and EcoRestore, as it represents the most cost - effective large -scale reliability solution to improve regional water supply reliability for all of Southern California. The Orange County water reliability supply analyses assumes the California WaterFix results in "recovery" of historical supplies in the amount of approximately 440,000 acre -feet per year on average and notes that adjustments to the project costs or supply development could result in changes to this recommendation; and, WHEREAS, Orange County ratepayers have invested millions of dollars to build and maintain the SWP as well as portions of Metropolitan's regional storage, distribution, and treatment systems that take delivery of SWP supplies. Modernizing the system through the California WaterFix will protect this investment for decades to come; and, WHEREAS, moving forward with the California WaterFix will not be an inexpensive endeavor; however, it is the most cost - effective investment of the ratepayers' dollars to maintain and continue our economic vitality for the region. Furthermore, all of the costs for California WaterFix will be paid for exclusively by water agencies benefiting from the project; and, WHEREAS, to do nothing in the Delta is far costlier to the businesses, residents, and economy in the State of California and Orange County than investing in the California WaterFix and California EcoRestore. NOW, THEREFORE, THE SEAL BEACH CITY COUNCIL DOES HEREBY FIND AND RESOLVE: Section 1. The City of Seal Beach does hereby support the California EcoRestore and California WaterFix Preferred Alternative (No.4A) as described in the environmental documents with reasonable adherence to the current, public operating criteria and cost allocation principles and assumptions.
