"Three major tornadoes have struck Moore in the last 15 years. In May 1999, 2003, and just last year, powerful winds caused catastrophic damage to homes.Recently, I spoke with meteorologist and engineer Tim Marshall who surveyed the damage on all three tornadoes, and he says he found that most homes were not even built to code.The code is to build your home to withstand wind gusts of 90 mph 33 feet above the ground.The code requires your home to be bolted to the foundation. According to Marshall, the code prior to 1999 also required nuts and washers on bolts into the foundation.After May 3, 1999, Marshall found that only 12.5 percent of homes rebuilt were bolted down. He stresses that homeowners need to build above code to withstand higher wind speeds.This includes making sure your roof is strapped to your walls and making sure you use a bolt, nut, and washer that tightens down the wall bottom plate.Taking these extra measures has been proven to withstand EF 2 to EF 3 strength tornadoes, or wind gusts up to 165 mph.Marshall says the good news is after May 20, out of the homes he looked at that were rebuilt, all were bolted down. However, none of them were strapped."^^<http://www.w3.org/2001/XMLSchema#string>
