The Bay Conservation and Development Commission (BCDC) is dedicated to the protection and enhancement of San Francisco Bay and to the encouragement of the Bay's responsible use. When BCDC was established, only four miles of the Bay shoreline were open to public access. By drawing attention to the Bay, the Commission has played a major role in making the Bay and its shoreline a national recreational treasure. The Golden Gate National Recreational Area and numerous local, regional, and state parks and recreation areas have been established around the Bay since the Commission was established.
