What wind speed should I use for my project?

To determine the wind speed to use for your project, visit the ASCE Hazard Tool.

This tool allows input of a project address and also returns flood, snow, ice & seismic information.

Additional notes:

 There are several ‘risk categories’ associated with a location that determine what wind speed to use. 

A building that’s a risk category I for example has a lower wind speed requirement than a more important risk category II or III building. 

We explain risk categories here.

** Be sure to verify with your local Building Department as these values may differ from municipality-specific requirements.
