Project Overview

Corte Madera Marsh Restoration Project

The Golden Gate Bridge, Highway and Transportation District (District) is proposing to construct the Corte Madera 4-Acre Tidal Marsh Restoration Project (Project) within the District’s 72-acre property located in Corte Madera, CA.

The primary goal of the Project is to restore four (4) acres to tidal marsh habitat, thereby fulfilling the District’s obligations to establish two (2) acres of tidal marsh suitable for California Ridgway’s rail, in accordance with the 1988 Corps permit (#17486N), and two (2) acres of tidal marsh habitat associated with a 1996 modification to District ferry operations at the Larkspur Ferry Terminal.

The proposed restoration efforts will restore tidal connectivity to the Project site and provide tidal marsh habitat in support of Federal-listed species such as the California Ridgway’s rail and salt marsh harvest mouse.
