Project Goals

The goals of the Cullinan Ranch Restoration Project are to:

  • Restore tidal influence to Cullinan Ranch allowing restoration of mature tidal marsh.
  • Provide a key public access point for the San Pablo Bay National Wildlife Refuge.

The objectives of the project are to:

  • Contribute to the increased provision of suitable habitat to support the endangered species in the larger San Francisco Bay ecosystem.
  • Increase visitation to the Refuge by providing an access point for people to learn about and enjoy the marsh.
  • Maintain equal level of protection to the Highway 37 embankment.
