It was established to provide offsite mitigation opportunities for vernal pool grassland and riparian habitats and several associated rare, threatened, and endangered species.
Wetland Resources, LLC received bank approval in 2006, and it has been amended twice. Three phases of vernal pool restoration were implemented, and a fourth and final vernal pool restoration phase is in planning. Wetland Resources, LLC hired RES to conduct the bank’s ecological monitoring, design, and implementation of future phases, compliance reporting, and credit sales.
The 1,815-acre Gridley Bank is located in rural Solano County, California, south of the City of Dixon and adjacent to the Solano Land Trust’s Jepson Prairie Preserve.
Numerous wetlands and vernal pools were preserved or restored within the property, along with habitat for special-status species, including California tiger salamander, vernal pool tadpole shrimp, vernal pool fairy shrimp, vernal pool conservancy shrimp, Swainson’s hawk, Delta green ground, Boggs Lake hedge hyssop, and others.
