It is the intent of the Legislature in enacting this article:
(a) To assure that cities and counties recognize that open-space land is a limited and valuable resource which must be conserved wherever possible.
(b) To assure that every city and county will prepare and carry out open-space plans which, along with state and regional open-space plans, will accomplish the objectives of a comprehensive open-space program.
