SUBJECT: The U.S. Army Corps of Engineers, Sacramento District, (Corps) is evaluating a proposal to establish the Antonio Mountain Ranch Conservation and Mitigation Bank, which would result in the establishment and restoration (including re-establishment and rehabilitation) of waters of the United States, including wetlands and streams in or adjacent to Orchard Creek within the Lower Sacramento, California (HUC 18020109) watershed. This notice is to inform interested parties of the proposed activity and to solicit comments. A copy of the Applicant’s Prospectus is available online at the following location:,P25_BANK_ID:6478,2907

PROJECT DESCRIPTION: The sponsor proposes to establish a 797.9-acre mitigation and conservation bank containing reestablished/restored vernal pools within the 172.5-acre disturbed area, restored/rehabilitated/enhanced stream credits within Orchard Creek, and perennial marsh rehabilitation and enhancement on the north central portion of the site. Table 1 of the Prospectus identifies the proposed type and quantity of credits. The proposed habitat development may require a Department of the Army permit evaluation based upon any work that may require the discharge of fill material into waters of the U.S. The attached drawings and the prospectus available on RIBITS provide additional project details.


    Environmental Setting. There are approximately 80.26 acres of wetlands consisting of 31.43 acres of vernal pools, 37.31 acres of seasonal wetlands and seasonal wetland swales, 7.99 acres of pond, approximately 6.38 acres (15,034 linear feet) of perennial streams, and 1.87 acres (6,704 linear feet) of intermittent streams within the proposed bank site. Approximately 160 acres of the site has been disturbed by agricultural leveling. The balance of the site is characterized by vernal pool grassland interspersed with ephemeral or intermittent streams and some perennial marsh habitat.

Based on the information provided, a Department of the Army permit will be required for some of the proposed activities.

OTHER GOVERNMENTAL AUTHORIZATIONS: The Interagency Review Team responsible for the review and approval of the proposed mitigation bank may include representatives from the Corps, U.S. Environmental Protection Agency, California Department of Fish and Wildlife, and U.S. Fish and Wildlife Service, or other agencies as appropriate.
