3-21-3.1. Additional procedures for extraterritorial zoning and subdivision regulation.
In addition to the powers authorized in Sections 3-21-2, 3-21-3 and 3-21-4 NMSA 1978, any county and any municipality may agree to authorize a joint municipal-county zoning authority to enact ordinances, regulations, or both, relating to approval and regulation of subdivisions within the extraterritorial zoning area as defined by the agreement creating the joint municipal-county zoning authority. Such subdivision ordinances and regulations shall be adopted, amended and enforced pursuant to Sections 3-21-3 and 3-21-4 NMSA 1978, as appropriate. Such subdivision ordinances and regulations may define "subdivision" in a manner which differs from the definitions set forth in Subsection A of Section 3-20-1 NMSA 1978 and in Subsection I of Section 47-6-2 NMSA 1978. The joint municipal-county zoning authority may also modify portions of the comprehensive plan, provided that such modifications leave unchanged those portions in the comprehensive plan that are not in the extraterritorial area.
