17.37.010 - Purpose.

Section 66412 of the Government Code of the state of California provides that lot line adjustments are excluded from the requirements of the Subdivision Map Act when they have been approved by the local agency or advisory agency. The purpose of this chapter is to provide a procedure for granting such approval. The lot line procedure is not intended to be used for subdividing property and may be used only in those situations where the provisions of the Subdivision Map Act and the Mono County subdivision code do not apply. The lot line adjustment procedure provided for in this chapter should include only those lot line adjustments that are of a minor and routine nature where extensive review and public involvement is not necessary.

(Ord. 83-446-K § 2 (part), 1983.)
