The Legislature further finds and declares that the coastal zone portion of the Santa Monica Mountains Zone has been evaluated as part of the California Coastal Zone Conservation Plan, and because of the unique, important, and threatened nature of the coastal-related resources within the coastal zone, the Legislature determined that the special coastal resources planning and management program established pursuant to the California Coastal Act of 1976 (Division 20 (commencing with Section 30000)) should apply within the coastal zone and that the local coastal program required by such act should be completed in a timely and effective manner by local governments and certified by the California Coastal Commission. It is the intent of the Legislature to facilitate early completion of local coastal programs for the coastal zone portion of the Santa Monica Mountains Zone and that accordingly the jurisdiction of the Santa Monica Mountains Conservancy should be extended to include, at the time of certification, those portions of the coastal zone for which a local coastal program has been certified.
