Cal. Gov't Code § 66478.11
(a) No local agency shall approve either the tentative or the final map of any subdivision fronting upon the coastline or shoreline which subdivision does not provide or have available reasonable public access by fee or easement from public highways to land below the ordinary high water mark on any ocean coastline or bay shoreline within or at a reasonable distance from the subdivision.
Any public access route or routes provided by the subdivider shall be expressly designated on the tentative or final map, and the map shall expressly designate the governmental entity to which the route or routes are dedicated.
(c) In making the determination of what shall be reasonable public access, the local agency shall consider:
(d) Nothing in this section shall require a local agency to disapprove either a tentative or final map solely on the basis that the reasonable public access otherwise required by this section is not provided through or across the subdivision itself, if the local agency makes a finding that the reasonable public access is otherwise available within a reasonable distance from the subdivision and identifies the location of the reasonable public access.
The finding shall be set forth on the face of the tentative or final map.
