The proposed regulation would assign a priority of very-high, high, or other for levee improvement funding to each island or tract located within the legal boundaries of the Sacramento-San Joaquin Delta and Suisun Marsh.

Pursuant to the proposed regulation, the California Department of Water Resources would fund levee improvement projects at very-high priority islands or tracts before funding levee improvement projects at high or other priority islands or tracts. If available funds are sufficient to fully fund levee improvements at the very-high priority islands or tracts, then levee improvements on high priority islands or tracts may be provided, and, after those projects have been fully funded, then levee improvement projects at other priority islands or tracts may be funded.

The proposed amendment would also require the DWR to submit an annual report to the Council including information describing Delta levee investments relative to the priorities and any variations from the priorities in the proposed regulation.

Yolo bypass levee construction.

The DLIS is a tool for State prioritization of investments in levee operations, maintenance, and improvements in the Delta. The DLIS aims to reduce the likelihood and consequences of levee failures to protect people, property, and State interests while advancing statewide water supply reliability and Delta ecosystem resilience in a manner that protects and enhances the Delta as a place where people live, work, and recreate.

The proposed regulation is intended to ensure State priorities are met as required by the Delta Plan. The rulemaking process typically involves multiple phases, including notice of potentially adopting or amending a regulation and a public comment period on the proposed regulation. A proposed regulation is subject to review by OAL, which is responsible for ensuring State agency compliance with the rulemaking procedures and standards set forth in the California Administrative Procedure Act.
