Wayne, the newest building code IBC 2009 has more detailed maps for a
lot of specific areas on the Florida coast, so you may be in an even
higher category (or less) locally.

Are there any web sites with maps for the IBC 2009 wind zones ?

I can't find the map he is talking about but this is where you can see
the FBC

Thanks.

Bear in mind these maps are just a guideline. Each AHJ will pick a
zone and all construction in that jurisdiction will be permitted based
on that zone as a general rule. They may want more on a barrier island
but in Lee County, Sanibel/Captiva and FMB are separate jurisdictions
so that line is easier to delineate. We only have 67 counties but
there are hundreds of AHJs. Sanibel, Cape, Bonita, FMB and the City of
Ft Myers all have their own building departments.
Florida only has one building code, but each AHJ will have his own
"interpretation" of what it says *;-) *

Florida's building code is the IBC with Florida amendments. Anyway,
when mapping wind speeds, you interpolate, meaning that if the locale
is between a 120mph isobar and a 130mph isobar, you can design for 125
as opposed to going with the higher value.
