Notice of Availability of DEIR for Lookout Slough Tidal Habitat Restoration and Flood Improvement Project



The California Department of Water Resources (DWR) has prepared a Draft Environmental Impact Report (Draft EIR) in accordance with the California Environmental Quality Act (CEQA) and Guidelines for the Lookout Slough Tidal Habitat Restoration and Flood Improvement Project (Proposed Project). The DEIR describes the Proposed Project and evaluates the potential environmental impacts associated with the Proposed Project.

The Draft EIR was released for public review on December 16, 2019. The Draft EIR will be available for review at libraries, DWR’s Division of Environmental Services, and on the DWR project website, as listed in this notice. Comments on the Draft EIR will be received for a 60-day period, commencing on December 16, 2019 and ending on February 14, 2020 at 5:00 p.m., after which a final EIR will be prepared containing the Draft EIR and responses to comments received.

DWR has issued this Notice of Availability to provide responsible agencies, trustee agencies, and other interested parties with information on how to access and comment on the Draft EIR.


The Proposed Project is designed to be a multi-benefit project to restore approximately 3,100 acres of tidal marsh, increase flood storage and conveyance in the Yolo Bypass, increase levee resilience, and decrease flood risk. Habitat restoration and flood improvement goals would be attained by excavating a network of tidal channels, constructing a new setback levee along Duck Slough, breaching and degrading the Shag Slough (Yolo Bypass West) Levee, breaching the Vogel Levee, and improving the Cache/Hass Slough Levee to function as a training levee.


The Proposed Project Site is a 15-parcel, approximately 3,400-acre area located in unincorporated Solano County, California, near the border with Yolo County. It is located approximately 20 miles southwest of Sacramento and 50 miles northeast of San Francisco, within the Liberty Island United States Geologic Service 7.5-minute quadrangle. The Proposed Project Site is bordered on the northwest by Duck Slough, the southwest by Cache and Hass Sloughs, the east by Shag Slough, and the north by Liberty Island Road.


The Draft EIR is being circulated for review and comment by appropriate agencies, organizations, individuals who have requested notification, and other interested parties. The Draft EIR was made available for public review and comment on December 16, 2019. The public review and comment period will extend for 60 days from this date, ending on February 14, 2020 at 5:00 pm. All public comments received during this time will become part of the public record; comments and responses to comments will become part of the Final EIR.
