The Legislature further finds and declares as follows:

1. (a) That, to achieve maximum responsiveness to local conditions, public accountability, and public accessibility, it is necessary to rely heavily on local government and local land use planning procedures and enforcement.
2. (b) That, to ensure maximum state and federal conformity with the provisions of this division; to protect regional, state, and national interests in assuring the maintenance of the long-term productivity of the Suisun Marsh; to avoid long-term costs to the public and a diminished quality of life resulting from the misuse of the marsh; to coordinate and integrate the activities of the many agencies whose activities impact the marsh; and to supplement the activities of such agencies in matters not properly within the jurisdiction of any existing agency; it is appropriate to provide for continued state planning and management through the San Francisco Bay Conservation and Development Commission, which since 1965 has exercised jurisdiction over a substantial portion of the Suisun Marsh pursuant to Title 7.2 (commencing with Section 66600) of the Government Code.
