VIRGINIA · ASCE 7-16 · WIND LOADS
Virginia Wind Load Requirements
From the Atlantic coastline through the Piedmont to the Blue Ridge — one commonwealth, one code, many wind environments.
ADOPTED CODE · STANDARD
The code Virginia builds to
The 2018 Virginia Construction Code references ASCE 7-16 for every wind load determination.
Building Code
2018 Virginia Construction Code (VCC), based on the 2018 IBC with state amendments.
VCC 2018ASCE 7 Edition
ASCE 7-16 governs MWFRS and Components & Cladding wind pressures statewide.
ASCE 7-16Authority (AHJ)
Local building officials and the Virginia DHCD enforce the code and review permits.
DHCD + LOCALPE Seal
A Virginia-licensed PE seal is required for commercial structures and engineered residential designs.
PE REQUIREDWIND ZONES · ASCE 7-16 Vult (RISK CAT II)
Coast runs high, inland runs lower
Design wind speed climbs toward the Tidewater and Chesapeake coast and eases across the Piedmont and mountains.
| Region | Character | Design Wind (Vult) |
|---|---|---|
| Eastern Shore | Chesapeake / Atlantic coastal | 125–150 mph |
| Coastal Virginia (Tidewater) | Hurricane & nor'easter exposure | 115–140 mph |
| Hampton Roads | Coastal metro | 115–130 mph |
| Blue Ridge Mountains | Elevation-dependent | 100–120 mph |
| Richmond Metro | Central inland | 105–115 mph |
| Piedmont Region | Rolling inland terrain | 100–110 mph |
| Shenandoah Valley | Valley channeling | 90–105 mph |
| Southwestern Virginia | Inland / mountain | 90–105 mph |
Coastal Tidewater and Chesapeake sites where basic wind speed exceeds 130 mph and lie within 1 mile of the mean high water line are wind-borne debris regions — glazing must be impact-resistant or shutter-protected per ASCE 7-16 Section 26.10.

DESIGN REQUIREMENTS
What Virginia design must address
Core obligations under VCC 2018 + ASCE 7-16, from coastal envelopes to elevated terrain.
Components & Cladding
Corner zones carry the highest pressures (1.5–2x field); edges run 1.2–1.5x.
C&C ZONESTopographic Kzt
Hills, ridges, and escarpments accelerate wind; Kzt is >1.0 near a crest, returning to 1.0 away from the feature.
CH. 26Wind-Borne Debris
Coastal openings within 1 mile of mean high water where V>130 mph need impact glazing or shutters.
26.10Exposure Category
B suburban/wooded, C open terrain, or D coastal/flat — selected from surrounding terrain.
B · C · DASCE 7-16 · RISK CATEGORIES
Higher risk, higher wind map
Each category reads a different wind speed map — higher categories use higher design speeds.
Category I
Agricultural and temporary structures — lowest design wind speeds.
LOW HAZARDCategory II
Standard residential, commercial, and industrial buildings — standard speeds.
STANDARDCategory III
Schools, assembly facilities for 300+, and jails — increased wind speeds.
INCREASEDCategory IV
Hospitals, fire stations, and emergency operations centers — highest speeds.
