Knightsen Wetland Restoration Project

Project Overview

Overview

East Contra Costa County Habitat Conservancy (ECCCHC) and the East Bay Regional Park District (EBRPD) purchased the former Cerri Ranch property in 2016 to protect it from development and restore Delta habitat. ECCCHC and partners are developing a habitat restoration project on a 645-acre property east of the Knightsen community. The project team is currently refining concept plans, considering multiple objectives that will create and restore wetlands and other habitat, manage storm water flows, improve Delta water quality, and explore potential future recreation opportunities.

Map of Project Area

Location

Knightsen is located in the Sacramento-San Joaquin Delta in Contra Costa County. The project site is located along the historic Delta shoreline.  Historically this side was a mosaic of tidal marsh, wetland, sand dune, grassland and oak savanna, Most of the property is farmed (irrigated agriculture) with a small portion that is seasonally grazed.

Background

A history of flooding and poor stormwater quality prompted the Contra Costa County Public Works Department, in conjunction with the Knightsen Town Advisory Council, to conduct a feasibility study to determine the best approach to address drainage concerns in this region. This study, as well as other studies undertaken since then, identified the 645-acre project site as a good location to direct and store stormwater, where natural wetlands could clean and filter the water before discharge to the Delta.

The East Contra Costa County Habitat Conservancy is leading the effort to develop the project. Conceptual alternative designs were completed and 2019 and work to refine the project continues.
