… The expansion of Wind Zone 4 was an unintended consequence of modifications intended to correlate the wind speeds of the code with the latest version of ASCE 7, ASCE 7-10. Wind Zone 4 consists of areas with a wind speed of greater than 170 mph and Miami-Dade and Broward Counties. The designation of the High Velocity Hurricane Zone (HVHZ) dictates that building products used within the zone are laboratory-tested to meet high standards of performance under the stress of extreme wind and pressure, and manufactured according to a quality assurance program that is third party approved. In the HVHZ, the 2010 FBCR specifies a wind speed of 175 mph in Miami-Dade County and 170 mph in Broward County.

If you live in Florida, in Miami/Dade, Broward Counties or Coastal Palm Beach County, you are in an HVHZ. HVHZ stands for High Velocity Hurricane Zones and is part of the Florida building code.
