Grant Amount:

$1,610,000

Location:

Montezuma Slough, Solano County, North Bay Region

Project Phases Funded by this Grant:

Design; Maintenance; Monitoring; Construction/Implementation

Measure AA Program Category:

Safe, Clean Water and Pollution Prevention Program; Vital Fish, Bird and Wildlife Habitat Program.

Summary:

The project consists of tidal and seasonal wetland restoration on approximately 630 acres of currently diked baylands along Montezuma Slough and enhancement of adjacent uplands in Suisun Marsh.

The 630 acres of baylands will be restored to 566 acres of tidal marsh and subtidal habitat, 45 acres of seasonal wetlands, and 19 acres of high tide refuge and bird nesting habitat. Approximately 220 acres of adjacent uplands will be enhanced to improve upland habitat quality.

The project includes initial placement of dredged materials to raise the site elevation followed by additional construction activities and then breach of the existing dikes to enable tidal action on the site. Most of the dredged material has been placed. The authorization is to fund the other activities necessary to restore the site.

The project is located at a position in the San Francisco estuary where freshwater outflow from the Sacramento-San Joaquin Delta mixes with saline water from San Francisco Bay. Tidal marsh in this mixing zone supports high primary productivity that fuels the aquatic food web and provides food for many native fish species.
