Document Description
The applicant is requesting approval of a land use permit for the purpose of establishing the Collier Canyon Mitigation Bank upon three contiguous parcels straddling the Alameda/Contra Costa County line just north of the city of Livermore. The proposed 188.8-acre CCMB involves the creation and rehabilitation of habitats for various special-status plant and wildlife species. The CCMB has been designed to result in the establishment of 17.29 acres of new wetlands by grading in areas adjacent to existing wetlands. Additionally, the project involves the rehabilitation of 1.78 acres of jurisdictional wetlands, 4.29 acres of perennial/ephemeral drainage, 10.25 acres of riparian woodlands, and 155.19 acres of upland grassland. The proposed CCMB would provide mitigation credits to offset both permanent and temporary impacts to waters of the US and CA. In addition, the bank would offset environmental losses resulting from unavoidable impacts associated with riparian habitat, will replace conservation values of habitats used by special-status plant and wildlife species and may be used to offset environmental losses resulting from impacts to special status species.
