San Francisco Bay Delta

Sears Point Tidal Marsh Restoration Project: Phase II

This project will restore tidal action to 960 acres and provide connectivity of tidal marsh habitat from the Sonoma Baylands to San Pablo Bay.  Restoration activities have been coordinated by the Sonoma Land Trust with CA Department of Fish and Wildlife (CDFW) and the US Fish and Wildlife Service (USFWS). EPA funds will be directed to grading, lowering, and breaching of the existing levee; excavation of a new channel to connect the site to the Petaluma River Navigation Channel; installation of key public access features; initial establishment of a vegetated transition zone on the new levee; and monitoring.
