Concord Community Reuse Project

Concord Community Reuse Project

The Concord Reuse Project is a proposed mixed-use development of residential, industrial, and community uses on approximately half of the 5028-acre former Inland Area of the Concord Naval Weapons Station, with habitat enhancement and management for special-status species on the remainder of the site.

H. T. Harvey & Associates was engaged by the City of Concord to revise the biological resources section of a revised draft Environmental Impact Report (EIR). Using existing information supplemented with our field surveys, we revised the biological resources chapter and responded to public comments, and the final EIR was certified. Our team also completed a detailed wetland delineation of the project site. We prepared a Biological Assessment to facilitate Federal Endangered Species Act consultation with the U.S. Fish and Wildlife Service (USFWS) and assisted the City, Navy, and USFWS during the consultation process, culminating in the USFWS’s issuance of a Biological Opinion. We are currently assisting the City with permitting, including Clean Water Act Section 404 permitting with the U.S. Army Corps of Engineers, Section 401 water quality certification with the Regional Water Quality Control Board, and California Endangered Species Act/Fish and Game Code Section 1602 permitting with the California Department of Fish and Wildlife. We have prepared a Long-Term Management Plan for the on-site mitigation area for listed species and a Habitat Mitigation and Monitoring Plan for habitat enhancements, including new amphibian breeding ponds, in the on-site conservation area. We continue working with the City’s team in designing on-site wetland mitigation and in designing the restoration of several miles of Mt. Diablo Creek, the centerpiece of the project. The conceptual design is being developed in concert with a hydrologic design for the creek to improve the creek’s flood capacity and enhance its natural processes.
