三角洲运输工程
政府. Gavin Newsom's 三角洲运输工程 proposes to modernize the state's water infrastructure in the Sacramento-San Joaquin Delta to increase the state’s water supply reliability for 27 million Californians.
The proposed project—identified as the Bethany Reservoir alignment—features two new state-of-the-art intakes with fish screens on the Sacramento River in the north Delta and a tunnel with a maximum diversion capacity of 6,000 cubic feet per second that would move water below the Delta to the Bethany Reservoir at the start of the 加州渡槽. A tunnel minimizes impacts to the Delta community and provides greater seismic resilience than a canal, and the location of the intakes provides resiliency to a climate-changed future, 以及极端的海平面上升. The fish screens and operational criteria are designed to meet all regulatory protections for sensitive fish species and water quality in the Delta. The proposed project would allow for the capture of water supplies during particularly wet periods. 在干燥和一般条件下, state project supplies would continue to move through the Bay-Delta, 就像他们188bet棋牌平台做的那样.
In December 2023, the California Department of Water 资源 released its 最终环境影响报告 进行三角洲运输工程. 阅读都市的 声明 最终EIR的发布.
Formed by the confluence of the Sacramento and San Joaquin rivers, the Delta serves as a critical pinch-point for the State Water Project, which on average provides about 30 percent of Southern California's water supply. 这个水源, along with the 科罗拉多河 and other water supplies across the West, are being threatened due to climate change and weather extremes.
The 2020-2022 drought was a powerful indicator of just how vulnerable the state project is, with historic low deliveries across the state. 在南加州, some communities could only get a fraction of the water they normally rely on, triggering forms of mandatory conservation for nearly 7 million residents. State project supplies are critically important to Metropolitan’s future reliability, along with investing in new local water sources, 促进加强自然保育, building a more flexible and interconnected regional water delivery system and creating more storage that allows us to bank more water in wet years for use when it is dry.
Metropolitan’s board and water leaders across the state will use the state's Environmental Impact 报告 进行三角洲运输工程, along with additional information to be developed in the months ahead, including a cost estimate and a project cost-benefit analysis, to determine how to best invest our resources in response to a changing climate, while also supporting the state’s coequal goal to protect, restore and enhance the Delta ecosystem.
Metropolitan will further assess the 三角洲交通工具 project through its Climate Adaptation Master Plan for Water, which will guide all of our investments in infrastructure, conservation and new supplies in the years to come.
