Amarillo wind load requirements on the extreme High Plains
Flat, treeless, tornado-prone Panhandle terrain pushes Amarillo design wind speeds among the highest inland values in Texas under ASCE 7-22.
ASCE 7-22 · WIND & EXPOSURE
Why the Panhandle drives Exposure C pressures
Hundreds of miles of flat, open terrain leave almost no surface roughness, so winds reach buildings near full strength.
Open, treeless terrain
Flat grassland and farmland with minimal obstructions place nearly all Amarillo sites in Exposure Category C.
EXPOSURE CPersistent high winds
Strong, year-round westerly winds and severe-thunderstorm straight-line gusts make this one of the windiest regions in Texas.
RISK CAT II 110–125Tornado Alley core
Amarillo sits in the heart of Tornado Alley; critical facilities often add tornado-resistant detailing (ASCE 7 Ch. 32 / ICC 500) beyond basic wind loads.

What you need to comply in Amarillo
Four inputs define a City of Amarillo Building Safety wind submittal under ASCE 7-22.
Design wind speed
110–125 mph 3-second gust for Risk Category II; higher categories read a higher-return-period map.
110–125 MPHExposure category
Exposure C governs nearly all sites; site-specific surface roughness per ASCE 7 §26.7 confirms it.
EXPOSURE CRisk category
Classify per ASCE 7-22 Table 1.5-1; higher categories select a longer-return-period speed map.
TABLE 1.5-1PE-sealed calcs
Commercial and engineered structures need MWFRS and C&C pressures sealed by a Texas-licensed PE.
