Mitigation Projects

Honker Bay Conservation Bank

The proposed Honker Bay Conservation Bank is located on approximately 112.34 acres along the southern edge of Suisun Marsh in Solano County. The Bank is located along the northern part of Honker Bay, east of Roaring River and south of Champion Slough on Wheeler Island.

Wildlands will restore, enhance, and permanently protect the conservation values of the site, providing compensatory mitigation that may be required by federal, state, and local agencies to offset effects of development activities on tidal marsh and aquatic habitat that supports state- and federally listed fish. The Bank is currently under review by the Conservation Bank Review Team (CBRT) consisting of the National Marine Fisheries Service (NMFS), U.S. Fish and Wildlife Service (USFWS), and California Department of Fish and Wildlife (CDFW).

The Bank offers an excellent opportunity to preserve and restore marsh habitat and will benefit the species which have special protection status under the federal Endangered Species Act (ESA) and/or California Endangered Species Act (CESA) including those listed below.
