Project Description

WRA performed numerous biological studies to assist our client in achieving their goal of developing a mixed-use project that includes residential, commercial, office, marina, and recreational uses within an existing marina along the Marin County shoreline.  The biological studies conducted by WRA on this 30-acre site identified extensive seasonal wetlands located within the marina and other sensitive resources located within the immediate vicinity.  WRA assisted developers with securing necessary environmental permits and approvals, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service.  WRA also assisted our client with a California Environmental Quality Act Biological Impact Analysis for the project.
