Why Arlington sits at 100–115 mph

Design speeds come from the ASCE 7-22 maps for North Texas — flat inland terrain with elevated severe-weather hazard, not a single fabricated figure.

Severe Thunderstorms

Supercells and downbursts drive the primary damaging-wind threat across North Texas.

PRIMARY HAZARD

DFW Tornado Alley

Tarrant County sees multiple tornadoes annually; critical facilities warrant added resilience.

REGIONAL RISK

Exposure Category B

Urban and suburban roughness dominates the city; verify per ASCE 7-22 Section 26.7 each site.

PRIMARY EXPOSURE

Flat North Texas Terrain

Minimal topographic effect — Kzt is typically 1.0 across Arlington's level ground.

Kzt ≈ 1.0

Exact site velocity depends on precise location within the city and local roughness. The WindLoadCalc.com calculator reads the correct ASCE 7-22 speed from any Arlington zip or address.

Risk category sets the speed map

Higher risk categories read a longer-return-period map, raising the design wind speed — there is no fixed multiplier.

Risk CategoryArlington Design SpeedTypical Building Types
Risk Category I~95–110 mphAgricultural, temporary, minor storage
Risk Category II100–115 mphHomes, commercial, hotels, standard occupancy
Risk Category III~110–125 mphSchools, assembly >300, AT&T Stadium, Globe Life Field
Risk Category IV~120–135 mphHospitals, fire stations, emergency shelters

CITY OF ARLINGTON · BUILDING INSPECTIONS

What you need to comply

The Arlington Building Inspections Division is the AHJ — every wind-load submittal is sealed by a Texas PE.

ASCE 7-22 Standard

Calculations follow the current edition referenced under the City of Arlington IBC adoption.

CODE EDITION

Sealed PE Calculations

All structural wind-load work is prepared and sealed by a Professional Engineer licensed in Texas.

TEXAS PE

Exposure Determination

Justify Exposure B (or local C transitions) over 20× building height per ASCE 7-22 26.7.

SITE ANALYSIS

Online Permitting

Submit through the city's digital permitting system for review by the Inspections Division.

AHJ SUBMITTAL

MWFRS & C&C Pressures

Provide both main-system and component-and-cladding pressures for every building element.

FULL PRESSURES

Assembly-Scale Review

Stadiums and large-span structures require peer review and specialized wind engineering.
