The Legislature hereby finds and declares that the Santa Monica Mountains Zone, as defined in Section 33105, is a unique and valuable economic, environmental, agricultural, scientific, educational, and recreational resource that should be held in trust for present and future generations; that, as the last large undeveloped area contiguous to the shoreline within the greater Los Angeles metropolitan region, comprised of Los Angeles and Ventura Counties, it provides essential relief from the urban environment; that it exists as a single ecosystem in which changes that affect one part may also affect all other parts; and that the preservation and protection of this resource is in the public interest.
