what is hvhz in florida 2006 code?
what is the definition on the high-velocity hurricane zone in the florida 2006 building code?  over 130 mph?  110 mph?
thanks,

from 2004 fbc:
"high velocity hurricane zone. this zone consists
of broward and dade counties."
it is what used to be the south florida building code incorporated into the state code and applies only to those counties listed.  note also that the fbc specifies the wind speeds to be used for each county in 1620.2.
the high velocity hurricane zone is used by broward (140 mph) and miami-dade (146 mph) county.
so the definition is irrelevant of wind speed, it depends if the county you are designing your project adopted this portion of the code.  as far as i am aware, only broward and miami-dade have adopted its use.
as a side note, per my discussion with the building official in miami-dade, you do not mix provisions. either you design for the 'regular' fbc sections or the hvhz sections, you do not use parts from each.
the hvhz is the old south florida building code with a new name. when they attempted to combine florida into one code they failed and instead of leaving the sfbc, to save face, they gave it a new name and put in the same binder. when in broward or dade you have to use hvhz and it is dfinitely different.
dade and broward
