New Mexico Statutes Chapter 47. Property Law § 47-6-11.1. Expiration of preliminary plat

A. An approved or conditionally approved preliminary plat shall expire twenty-four months after its approval or conditional approval, or after any additional period of time as may be prescribed by county regulation, not to exceed an additional twelve months. However, if the subdivider proposes to file multiple final plats as provided for under county regulations governing phased development, each filing of a final plat shall extend the expiration of the approved or conditionally approved preliminary plat for an additional thirty-six months from the date of its expiration or the date of the previously filed final plat, whichever is later. The number of phased final plats shall be determined by the board of county commissioners at the time of the approval or conditional approval of the preliminary plat.

B. Prior to the expiration of the approved or conditionally approved preliminary plat, the subdivider may submit an application for extension of the preliminary plat for a period of time not exceeding a total of three years. The period of time specified in this subsection shall be in addition to the period of time provided in Subsection A of this section.

C. The expiration of the approved or conditionally approved preliminary plat shall terminate all proceedings on the subdivision, and no final plat shall be filed without first processing a new preliminary plat.
