CA Gov't Code Section 66478.13

No local agency shall issue any permit or grant any approval necessary to develop any real property which is excluded from regulation under this division as a subdivision pursuant to subdivision (d) of Section 66426 because such property is in excess of 40 acres and was created as such a parcel after December 31, 1969, when such property fronts on the coastline or a shoreline, unless it finds that reasonable public access has been provided from public highways to land below the ordinary high-water mark or any ocean coastline or bay shoreline or any water of a lake or reservoir upon which the real property fronts. “Reasonable public access” as used in this section shall be determined by the local agency in which the real property lies. In making such determination the local agency shall use the same criteria as those set forth in subdivisions (c) and (d) of Section 66478.11 and subdivisions (c) and (d) of Section 66478.12.
