The Newark Slough Full Delivery/ Turnkey Mitigation Site is a permittee-responsible mitigation (PRM) site in Alameda County, California, providing permanently protected habitat for the Salt marsh harvest mouse (Reithrodontomys raviventris). Situated in an area of the South San Francisco Bay that was historically tidal marsh, the preserve offers a high-quality, intact tidal wetland ecosystem that supports critical habitat functions for this federally and state-listed endangered species, which could be used for turnkey, PRM, or full delivery mitigation solutions.

Located north of Newark Slough, the preserve benefits from tidal influence that extends through its secondary channel system, ensuring natural hydrological connectivity across the marsh plain. This healthy remnant of historic tidal marsh consists of a mosaic of habitats, including slough channels, tidal marsh wetlands, and upland transition zones, all of which provide essential resources for the Salt marsh harvest mouse and other sensitive tidal species.

With intact native habitat and natural tidal function, the Newark Slough Mitigation Site is a proven option for turnkey, full delivery, or permittee-responsible mitigation, in compliance with state and federal regulations.
