The Halo Ranch Mitigation Bank is an approximately 175-acre property located in Sonoma County, California, and is ideally located to integrate into existing ecologically valuable conservation areas. The Halo Ranch property connects to the existing tidal marsh within the Petaluma River/marsh complex and is adjacent to the Petaluma Marsh Wildlife Area, which is the largest remaining natural tidal marsh habitat remaining in the San Pablo Bay. The area supports a wide variety of native wildlife including the Federal and State-listed endangered California Ridgway’s rail (Rallus obsoletus obsoletus) and salt marsh harvest mouse (Reithrodontomys raviventris).

The Halo Ranch Mitigation Bank will rehabilitate, re-establish, and enhance threatened and endangered species habitat and habitat credits will be available for impacts permitted under Sections 401 and 404 of the Clean Water Act (CWA) (33 U.S.C. § 1251 et. seq.) and under the Porter-Cologne Water Quality Control Act (Water Code § 13000 et. seq.).
