Important Notes

New Mexico spans from 2,842 ft (Red Bluff Reservoir) to 13,167 ft (Wheeler Peak). Key hazards: WILDFIRE — extensive WUI zones, especially in mountain communities and forests (Cerro Grande Fire 2000, Las Conchas Fire 2011). EARTHQUAKE — Rio Grande Rift creates significant seismic hazard; Albuquerque and Santa Fe are SDC D. FLOOD — flash flooding is common in arroyos and desert areas. EXPANSIVE SOILS — bentonite clay found throughout the state causes foundation damage. EXTREME UV — high elevation means intense solar radiation. DUST STORMS — high winds create visibility hazards and require sealed building envelopes. UNIQUE EARTHEN BUILDING tradition — NM is the only state with dedicated codes for adobe, rammed earth, and straw bale construction.
