BASIC WIND SPEED:
The basic wind speed in miles per
hour, for the development of wind loads, shall be determined from Figure1 1609
A, B, and C. The exact location of wind speed lines shall be established by
local ordinance using recognized physical landmarks such as roads, canals,
rivers and lake shores whenever possible. Because of the many wind speed lines
of the multiple Risk Categories, there are not appropriate physical landmarks to
provide an accurate and orderly reflection of these boundaries. To determine the
applicable wind speed of a particular parcel, Palm Beach County has developed
separate Geographic Information Systems (GIS) tools for each of the Risk
Categories.
WIND-BORNE DEBRIS REGION:
Areas within hurricane-prone
regions located:
- Within 1 mile (1.61 km) of the coastal mean high water line where the ultimate design wind speed Vult is 130 mph (48 m/s) or greater; or
- In areas where the ultimate design wind speed Vult is 140 mph (53m/s) or greater. Linear interpolation between contours may not be utilized in the determination of the Wind Borne Debris Region. All of Unincorporated Palm Beach County is within the Wind Borne Debris Region.
