Seismic code battle

The battle over new and stricter seismic building standards is one that shouldn’t be fought.

Area home builders, however, have appealed to state legislators for relief from the new codes and lawmakers have responded. Bills introduced in the House and Senate would grant local governments the power to adopt building code amendments that are less stringent than those enforced by the State Fire Marshal’s Office. Under current law, local amendments are supposed to be at least as strict as the statemandated codes.

But here is why this should not be an issue. Memphis is close to the New Madrid Seismic Zone.

Homebuilders said the added cost — 10-25 percent — to build a new home under the stricter code would chase away prospective homebuyers. Some structural engineering studies report, though, it would only add 1-5 percent to the cost of new home. As expected, insurers, the Fire Marshal’s Office and structural engineers strongly opposed the bill.

But here is the heart of the matter: The new code will not make a home earthquake proof, but it will make it earthquake resistant. If a minor quake happens, the new code makes it likely the house would escape damage. If a moderate or severe quake occurred, the code makes it unlikely the house would collapse.

Some home builders maintain the risk of a severe earthquake here doesn’t justify of cost of meeting the new code. But, that is a big gamble when talking about the public safety.
