The Next L.A. / Reinventing Our Future : PREPAREDNESS : Idea File: Seismic Veto

How It Works

Give earthquake experts veto power over local zoning decisions and construction plans to ensure seismic safety. As part of every zoning request or construction proposal, an earthquake engineer would have to certify that a proposed building or home incorporates all precautions necessary to ensure they can withstand a major earthquake. To make certain that contractors comply, no building would be certified for occupancy until independent earthquake specialists had inspected the actual construction. To ensure that owners of older buildings comply with retrofitting requirements, the earthquake engineers would have authority to close a building or bridge if repairs are not undertaken in a timely way.

Benefits

The recent Northridge quake underscored the effectiveness of proper engineering when it comes to avoiding damage or injuries. Experts say that making a building strong enough to withstand most quakes only adds about 10% to its cost. Although earthquake engineers and scientists often serve as consultants on major projects or advise local governing bodies on building codes, their advice often is ignored. As memory of a major quake fades, so usually does the zeal with which earthquake regulations are enforced.

Short-term or Long-term Impact?

Short-term. Enough is known already about earthquake engineering precautions that stringent enforcement of existing regulations would dramatically enhance safety. Already building codes are being strengthened as a result of the Northridge quake. As engineering expertise improves and new techniques are developed, however, earthquake experts could ensure they are adopted in new buildings and retrofitted to older structures. With sufficient local political power, scientists could ensure that quake safety is not sacrificed in the name of keeping down costs or encouraging local development.

Supporters

Rental tenants, office workers, students tend to back the idea.

Opponents

Many developers and building owners oppose the idea. Governing bodies may be reluctant to cede such power to non-elected experts. There also is nothing to prevent scientists from being co-opted by real estate interests or the construction industry.

The Costs

Added administrative costs. Higher builing costs.

Reality Check

Unlikely.
