The prevailing mindset is that to build homes to withstand these severe wind events would not be economical, however engineers are coming out saying that is a fallacy as illustrated by the 'Insight' article below. As population densities and suburban sprawl continue to transform the midwest, more communities are going to get "in the way", and by looking at the graphic below, they already are:

Just like new flood maps take time to create, changing building codes isn't something that can happen overnight, but the 'can do' attitude that exists in Tornado country means that no one is going to wait to rebuild, revised codes or not. By waiting too long to strengthen codes many homeowners may face a similar fate next time the sirens go off.

Wow, that tornado track graphic is quite something. The impact that zoning and ordinances have on everyday life is astounding and largely unrecognized. Zoning impacts everything from the way a community looks and feels, to the soundness of the buildings and infrastructure that are the trees in the forest.
ReplyDeleteAnd as you described, a can-do attitude is something to be admired; I would imagine those who are rebuilding quickly know as well as anyone what it will take to build back even stronger. At the same time there is wisdom in a thoughtful approach to zoning and rebuilding, and thoughtful considerations for codes in other regions that face similar hazards; but as you say it's imperitive that those changes are on the table now....And while I know that the insurance industry and simple economics motivate code changes, I think meaningful public understanding of mitigation strategies like code updating is essential to buy-in and ultimately better community in the long run.
Although it’s not necessarily directly relevant, there are some parallels to the efforts at greening. Here are two articles about Pittsburgh. http://www.organicgardening.com/living/pittsburgh?page=0,1 http://www.nytimes.com/2009/04/01/business/01pitt.html?pagewanted=1&_r=0
Julia, you're right about the impact zoning has on a multitude of facets of community life but when was the last time you heard people talking about zoning in casual conversation? I agree with you on your view that there needs to be more done to make the importance of these issues tangible, because as it stands zoning isn't the sexiest topic in the world; and therein lies the challenge of creating an environment of preparedness at a local level--what does it take for a community to buy into and ultimately take ownership of the initiatives that will eventually limit the losses when a disaster strikes?
