Otero County, NM Historic Preservation: Historic-Cultural Monuments (2026)

Otero County's Subdivision of Land chapter folds cultural resource protection into the plat approval process rather than running a separate landmarks program. Under § 200-31.B, anyone proposing to subdivide land in the county must review the latest edition of the State Register of Cultural Properties that the State Historic Preservation Division has provided to the county. If no registered property falls inside the proposed subdivision's boundaries, the subdivider files a signed affidavit saying so as part of the application package. If a registered property does fall inside the boundaries, the subdivider must instead file an affidavit disclosing that fact, which triggers the county's own consultation with the Historic Preservation Division pursuant to the state's Cultural Properties Act, NMSA 1978 §§ 18-6-1 through 18-6-17.

Section 200-31.A layers on a separate unmarked-burial rule: the county's subdivision regulations declare that any unmarked human burial in the state receives legal protection, and every subdivider must comply with NMSA 1978 § 18-6-11.2, which bars knowingly or willfully excavating, removing, disturbing or destroying a burial in an unmarked burial ground unless the State Medical Investigator or the State Cultural Properties Review Committee, with the State Archaeologist and State Historic Preservation Officer concurring, has issued a permit. This disclosure obligation is layered on top of the terrain management, drainage, and utility disclosures required elsewhere in § 200-12, so a subdivision application that skips the cultural properties affidavit is treated as incomplete for Planning Coordinator review under § 200-13.
