Disclaimer
Hazard loads are interpolated from data provided in ASCE 7 and rounded up to the nearest whole integer. Per ASCE 7, islands and coastal
areas outside the. last contour should use thelast wind speed contour of the coastal area — in some cases, this website will extrapolate past
the last wind speed contour and therefore, provide a wind speed that is slightly higher. NOTE: For queries near wind-borne debris region
boundaries, the resulting determination is sensitive to rounding which may affect whether or not it is considered to be within a wind-borne
debris region.
Mountainous terrain, gorges, ocean promontories, and special wind regions shall be examined for unusual wind conditions.
