Wind speed maps for building construction

On March 15, 2012, The 2010 Florida Building Code takes effect statewide. The new wind speed maps as contained in ASCE7-10 are incorporated into the code. There have been changes in the contours of the wind zones, the location of the wind-borne debris region(s) as well as the provisions for the calculation of pressures. Please click above to see the wind speed maps for Volusia County and also to determine what areas are subject to wind-borne debris requirements.

To verify the base wind speeds and wind-borne debris region for a property depending on type of building:

1. Locate the parcel on the map by using the map and using the map tools to pan and zoom to a local level view.
2. Determine the category of building that you are inquiring about:

   • CAT 1 BLDGS – Agricultural buildings, storage buildings, screen rooms and similar structures

   • CAT 2 & 3 BLDGS - Single family residences, duplexes, townhouses, schools colleges and similar structures

   • CAT 4 & Health Care Facilities – Hospitals, police stations, fire houses, emergency management facilities and similar structures

3. To establish your base wind speed:

   • Locate the main heading “Florida Building Code Wind Map” in the Layers section on the left side of the map. Place a check mark in the box next to the heading by clicking the box.

   • Next; locate the “Windbourne” heading in the layers section. Place a check mark in the box next to the heading.

   • Next; place a check mark in the box next to the category of building that corresponds with your inquiry. After the map processes the request, match the color of the map to the legend in the building category chosen and read the wind speed number just to the right of the color. This is your basic wind speed.

4. To determine if your property is impacted by the wind-borne debris region:

   • Locate the main heading “Florida Building Code Wind Map” in the Layers section on the left side of the map. Place a check mark in the box next to the heading by left clicking the box.

   • Next; locate the “Windborne” heading in the layers section. Place a check mark in the box next to the heading.

   • Next; place a check mark in the box next to the category of building that corresponds with your inquiry. After the map processes the request, match the color of the map to the legend in the building category chosen. If it's in the shaded area your property is subject to wind-borne requirements.
