"[S]econd printing of the San Francisco Bay Plan. Since it was originally adopted by the Commission in 1968, the Bay Plan has served the people of the region and the state as the instrument conceived of in the McAteer-Petris Act passed by the Legislature in 1965: 'a comprehensive and enforceable plan for the conservation of the water of San Francisco Bay and the development of its shoreline.' As foreseen by the original Commission, the Bay Plan has been amended from time to time within the intent of the McAteer-Petris Act to keep pace with the needs and desires of the public through the intervening years. Nevertheless, the essential substance and character of the Plan remains useable and relevant to the present day, both as a set of policies to guide the regulatory activities of the Commission and as a plan for the long range conservation and development of the region's most valuable resource, San Francisco Bay and its shoreline. The present printing contains all of the Bay Plan map and text amendments that have been adopted by the Commission since 1969 to 1979"--Letter of transmittal.
