Where the numbers come from
Most Texas and Louisiana jurisdictions adopt the International Building Code, which refers to ASCE 7 for wind loads. Design wind speed depends on location, building risk category and surrounding terrain (exposure). Open lots usually see higher exposure than sites surrounded by buildings.
Coastal differences
Gulf Coast counties are designed to higher wind speeds than inland areas, and some coastal areas carry additional windstorm requirements. Check with your jurisdiction and insurer.
Soils and foundations
Carport columns sit on foundations sized for wind uplift, overturning and the soil. Soft, high-water-table soils common in south Louisiana and expansive clays found in parts of Texas can call for deeper or larger foundations. A geotechnical report is the best input.
Permits
Most cities require plan review and a permit for a commercial carport. Review time and required documents vary. Superior sends submittals before installation to support the process, and your general contractor or owner usually pulls the permit.
