Project Description

Sensitive habitat along San Rafael shoreline

Sensitive habitat along San Rafael shoreline

The Loch Lomond Marina added mixed-use development to their 30-acre property in Marin County in the form of new residential, commercial, and recreational structures. The development project also included the placement of riprap along the marina’s breakwater, installation of a floating dock, and pile replacement.

WRA performed the biological studies and prepared the necessary permit applications on behalf of this project. Specifically, WRA performed a California Environmental Quality Act (CEQA) Biological Impact Analysis, helped secure permits from the Bay Conservation and Development Commission (BCDC), the U.S. Army Corps of Engineers, and the Regional Water Quality Control Board, and helped the client through Endangered Species Act consultations with U.S. Fish and Wildlife Service and the National Marine Fisheries Service.

WRA provided project design guidance to balance the goals of our client with local, state, and federal regulatory requirements with public concern.  We ultimately helped achieve the client’s goals in an environmentally responsible manner without the need for extensive permitting or mitigation requirements.  Currently, WRA is helping this client with additional permit applications for new upgrades to the marina, including the replacement of dock decking and marine fuel dock equipment.
