The new 2010 Florida Building Code will be implemented on March 15, 2010, and it includes significant changes to areas of South Florida. Specifically, the High Velocity Hurricane Zone Areas have been increased to include a much larger land mass and now covers areas that were not in the 2007 Florida Building Code. How will these changes affect contractors, manufacturers and permitting in South Florida? Until the changes are fully implemented nobody really knows for sure.
Tom Johnston, president of the International Hurricane Protection Association has the opinion that, “this adoption of ASCE 7-10 places an unnecessary burden on manufactures to update their product approvals to reflect a new code version when very little material differences have occurred. In addition, a net result of slightly less stringent design pressures is not a step in the right direction. All of this occurring during these difficult economic times makes this code modification even more of an ill conceived decision.”
According to the Home Builders Assocition, for central and south Florida the WBDR is increased and now will include all of the following; Miami-Dade, Broward, Monroe, Palm Beach, St. Lucie, Indian River, Brevard, Volusia, Pinellas, Manatee, Sarasota, Polk, Charlotte, Lee, Glades, Hardee, Hendry, Okeechobee, and Highlands. The result of these changes will mean there will be new areas with requirements for opening protection in accordance with Chapter 16 of the code.
There are also changes to the Energy Code which will affect Miami-Dade, Broward and Palm Beach Counties, but it seems, that the largest impact of the new Code from a cost and procedural stand point, will affect Central Florida more so than South Florida. By no means does that diminish the increased costs for building permitting. Procedural changes that building departments will institute will require contractors to produce additional paperwork and forms, and then there is the increased costs incurred by manufactures that will be pasted on to consumers. Let’s not forget the additional costs that the local architects and engineers will need to pass on the their Clients.
To summarize, it is a good thing that the HVHZ areas have been increased. Yes! The Wind Born Debri Regions in the 2007 and earlier Codes never made any sense, but have the other changes made buildings any safer? Or, have the changes just added more costs to the consumer, created more bureaucratic procedures and paperwork, and made the process of designing, building and permitting a construction project more of a nightmare that it already is, in Miami-Dade, Broward and Palm Beach Counties? Only time will tell!
It is 2010 but we have finally reached 1984. The Orwellian concepts of loss of personal freedom and state authority seem to have become not just a possibility but a reality. Our lighting speed information age has given everyone instantaneous access to all sorts of data, including personal information. That information is also available to the government.
I was listening to one of the radio talk shows and the discussion was about intrusive government. One of the commentators commented that he had heard of a local government using aerial photos to monitor construction that was performed without permits, by homeowners. The talk show host said that he did not believe it was true. Well, I can tell you first hand that it is true.
Several months ago I walked into one of the smaller building departments in Miami-Dade County. As I was waiting, I noticed that one of the staff was using Google Earth to scan residential properties and was comparing the aerial photos it to the historical permit data. Your are probably saying to yourself that this is just an isolated incident. Not so! In a meeting I had with an environmental department staffer, not too long ago, I was shown how they track the number of trees on a property by using aerial photos. If a tree is missing and no permit was pulled for removal a hold is placed on that property.
The aerial photo above is from Google Earth of a neighborhood where I once owned a home. You can clearly see pools, fences, sheds, trees, and the foot print of the house. Even the color of the roof tile, which some cities regulate. Big brother is watching!
We are now well into the the 2010 hurricane season. Nothing major has occurred affecting South Florida, but it only takes that one storm. After living through an evening in August of 1992 with Andrew pounding on the doors, and the boarded-up windows of the home I was staying in west Miami-Dade, I am fully aware of the destruction that one storm can do. A long, and what seemed to be a never ending evening in darkness hearing what sounds like the thunder of a train going by for hours is something you never forget.
Back then, the South Florida Building Code was about as thick as a paperback romance novel. Hurricane Andrew put and end to that real fast! Now, almost twenty years later, the Florida Building Code fills a cabinet shelf with volumes and volumes of 3″ loose leaf binders. Like any government generated rules and regulations some is genuine and serves the purpose it was created for, but other portions are created with political motivations. That leads me to the following observations. As you can see by the map to the above left, the yellow areas are considered, high velocity hurricane zones. The yellow areas encompass all of Miami-Dade County and Broward County, and a portion of Palm Beach County. Within the yellow areas there are degrees of wind velocity. They range from 120 mph -150 mph, but what is 30 mph between friends. If you look closely, the highest wind velocities are at the tip of Florida, concentrated on the eastern coast.
I am not a scientist, an engineer or a meteorologist but I am a thinker. Hurricanes have hit Florida from the Gulf as will as the Atlantic. Wilma in 2005, which I had the pleasure of experiencing, hit Florida on the Gulf side and went northwest through Florida. They also just don’t hit the tip of Florida as the wind borne debris map seems to indicate. When you look at the below satellite photos of Andrew and Wilma, and then compare it the the high velocity hurricane zones you are probably scratching your head.

So! My point is, get prepared and be prepared no matter where you live in Florida. Hurricanes are not going to follow maps created by bureaucrats. Also! It’s a little late now, but in the future, if you are doing any construction, build it to withstand 150 mph winds. You can always build to exceed Code!
