Cal. Government Code § 66601

The Legislature further finds and declares that uncoordinated, haphazard filling in San Francisco Bay threatens the bay itself and is therefore inimical to the welfare of both present and future residents of the area surrounding the bay; that while some individual fill projects may be necessary and desirable for the needs of the entire bay region, and while some cities and counties may have prepared detailed master plans for their own bay lands, a governmental mechanism must exist for evaluating individual projects as to their effect on the entire bay; and that further piecemeal filling of the bay may place serious restrictions on navigation in the bay, may destroy the irreplaceable feeding and breeding grounds of fish and wildlife in the bay, may adversely affect the quality of bay waters and even the quality of air in the bay area, and would therefore be harmful to the needs of the present and future population of the bay region.
