Environmental Planning

On January 15, 2020, DWR issued a Notice of Preparation (NOP). The NOP notified the public that an Environmental Impact Report (EIR) is being prepared for the proposed Delta Conveyance Project. The NOP also solicited responses from agencies, organizations, and members of the public regarding the scope and content of the environmental analysis in the EIR. To facilitate public input during this process, DWR also held scoping meetings throughout the state. The scoping period concluded on Friday, April 17.

NEPA

USACE has informed DWR that it will conduct federal environmental review of the proposed Delta Conveyance Project. USACE, which has regulatory authority over certain actions within specifically defined waters in the United States, will prepare an Environmental Impact Statement (EIS) under the National Environmental Policy Act. The EIS scoping period is now open.
