Present Land Use
Open Space and Industrial land use designations Once complete, the majority of the remediated project site would continue to function as a wetland/marsh habitat with no change in land use to the upland portions of the site.
Document Description
The project will consist of two phases: (1) excavating and dredging a new alignment east of the existing Peyton Slough, then rerouting the tidal exchangae between the Carquinez Strait and McNabney Marsh via the new alignment, and (2) dewatering, filling, then capping the existing Peyton Slough. A layer of soil will be placed above the cap within which natural habitat will be re-established. A new, full slough re-alignment will begin at a location approximately 200 feet north of the railroad crossing at Waterfront Road and continue to the Strait. The new alignment will run parallel to and to the east of the existing Slough, breaching the levee that separates the northern and southern sections of the Site. The project will consist of the following major activities; site preparation and tide gate installation, removal of certain materials, excavation in the new alignment, transition to new alignment, dewatering excavated materials, and capping the existing Slough.
