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. 

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, 以及其他信息, such as the state’s benefit-cost 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. 

On 2024年5月16日 the Department of Water 资源 released a 成本估算和效益成本分析. 大都会的声明.

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.

环境影响报告  

The environmental review process began in January 2020 when DWR released a 筹备通知书 进行三角洲运输工程. 2020年12月, Metropolitan's board voted unanimously to fund the district's share of the environmental planning and pre-construction costs, 加入其他国家水务承包商. 

2022年7月 EIR草案 公开征求公众意见.  This report evaluates and identifies potential environmental impacts of the proposed project and alternatives. The final report was released in December 2023 and will allow Metropolitan to conduct its own analyses and beginning in mid-2024 evaluate the potential costs and benefits of the project in support of our 董事会’s decision-making process.

在未来的几个月, DWR will negotiate permits in compliance with the California Endangered Species Act and federal Endangered Species Act, as well as a Change in Point of Diversion from the State Water 董事会 to ensure the new north Delta intakes would be operated to meet current laws, regulations and protections in the Delta. 

草案 社区福利计划框架 was included in the Draft Environmental Impact 报告, signaling DWR’s commitment to ensuring benefits for the Delta community and providing an opportunity for the public to comment on the concepts included in the framework.

通过最终EIR认证, the Community Benefits Program will officially become part of the proposed 三角洲运输工程 under consideration by Metropolitan’s board and other water leaders across the state.
