Throughout September, the Department of Water Resources (DWR) continued to prepare for the environmental review of a single tunnel solution to modernize State Water Project infrastructure. The department anticipates that the formal environmental review process will begin with the Notice of Preparation (NOP) under the California Environmental Quality Act (CEQA) later this year. While moving toward the NOP release, DWR continues to work on the foundational components – including data collection to support preliminary review and consultant selection – of environmental compliance that are not project specific.

September activities:


  • DWR continued the public process of negotiating proposed amendments to the SWP water supply contracts for cost allocation of a potential Delta Conveyance facility. Information and background on this process may be found here.
