Mitigation Projects

North Suisun Mitigation Bank

Established on 612 acres in Solano County, California, the Bank provides mitigation and conservation credits for agency-approved impacts to wetlands, associated vernal pool species such as the vernal pool fairy shrimp, vernal pool tadpole shrimp, and Contra Costa Goldfields, and the California tiger salamander (Ambystoma californiense).

The goal of the Bank is to preserve and maintain the quality of the existing vernal pools, swales and other seasonal wetland habitats on the site, and to create additional vernal pool habitat in order to provide compensatory mitigation for offsite projects. The habitats on the Bank include approximately 45 acres of enhanced and restored vernal pools, approximately 127 acres of preserved vernal pools and swales, and 388 acres of upland habitat.

Special-status wildlife species found at the site include:

  • Vernal pool fairy shrimp (Branchinecta lynchi)
  • Vernal pool tadpole shrimp (Lepidurus packardi)
  • California tiger salamander (Ambystoma californiense)
