California Code, Public Resources Code - PRC § 30603.1

(a) In any city and county which so requests, the commission may adjust the inland boundary of the area within which the issuance of coastal development permits may be appealed to the commission pursuant to paragraph (1) of subdivision (a) of Section 30603. Any such adjustment shall be made solely to avoid the circumstance of having the boundary of that area bisect an individual parcel of property. The adjustment may be made landward or seaward, but shall be the minimum distance necessary, consistent with the policies of Chapter 3 (commencing with Section 30200), to avoid bisecting a parcel of property.

(b) If the commission subsequently finds that the circumstances which warranted a boundary adjustment pursuant to subdivision (a) have changed, it may, after notice to the city and county, readjust the boundary so that it is consistent with the changed circumstances. The requirements of subdivision (a) shall apply to any such boundary adjustment.
