(a) On or before October 1, 1980, the commission shall submit to the City of Carlsbad an initial draft of the land use portion of the local coastal program for the area specifically delineated on maps 154 and 155 which have been placed on file with the Secretary of State on April 22, 1980.
(b) On or before July 1, 1981, the commission shall, after public hearing and consultation with the City of Carlsbad, adopt a local coastal program for that area within the City of Carlsbad which is specifically delineated on maps 154 and 155 which have been placed on file with the Secretary of State on April 22, 1980. The local coastal program for such area shall, after adoption by the commission, be deemed certified, and shall, for all purposes of this division, constitute the certified local coastal program for such area. The local coastal program for such area may be amended pursuant to the provisions of this division relating to the amendment of local coastal programs. In addition, until such time as (i) the City of Carlsbad adopts or enacts the implementing actions contained in any such local coastal program, or (ii) other statutory provisions provide alternately for the adoption, certification, and implementation of a local coastal program for that area, the local coastal program required by this subdivision may also be amended by the commission at the request of any owner of property located within the area. For administrative purposes, the commission may group these requests in order to schedule them for consideration at a single commission hearing; provided, however, that the commission shall schedule these requests for consideration at least once during each four-month period, beginning January 1, 1982. After either of these events occur, however, these property owners shall no longer be eligible to request the commission to amend the local coastal program.
(c) If the commission fails to adopt such local coastal program within the time limits specified in this subdivision, such area shall be excluded from the coastal zone and shall no longer be subject to the provisions of this division. It is the intent of the Legislature, in enacting this section, that a procedure to expedite the preparation and adoption of a local coastal program in this specified area be established so that the public and affected property owners know as soon as possible what the permissible uses of such lands are.
(d) This section is not intended and shall not be construed as authorizing any modification, extension, or alteration in any deadline or other provisions of any contract between the commission or any regional coastal commission and any person, business, or corporation with respect to planning services for the area delineated on maps 154 and 155.
