Tribal engagement is an important component of every major project led by the State of California, providing an opportunity for government-to-government consultation, and collaboration and coordination between Tribal leaders and project proponents. Guided by the Governor’s Executive Order B-10-11, the Department of Water Resources’ (DWR) Tribal Engagement Policy, the California Environmental Quality Act (CEQA) and state policies regarding consultation with California Native American Tribes, the California Aqueduct Subsidence Program’s (CASP) planning process includes significant Tribal engagement. This includes engagement with California Native American Tribes on Tribal Cultural Resources (TCRs) in accordance with the requirements of CEQA (Sections 21080.3.1, 21080.3.2, 21082.3 of the California Public Resources Code), commonly referred to as AB 52 requirements (added to CEQA through Assembly Bill 52 of 2014).

DWR is committed to a robust, collaborative, and transparent Tribal engagement process that provides for meaningful information sharing and opportunities for input. Below is a record of pertinent DWR CASP planning process Tribal engagement activities by project year.
