LA Mayor Proposes Earthquake Retrofits On Thousands of Buildings
HughPickens.com writes The LA Times reports that Ls Angeles Mayor Eric Garcetti has proposed the most ambitious seismic safety regulations in California history that would require owners to retrofit thousands of buildings most at risk of collapse during a major earthquake. "The time for retrofit is now," says Garcetti, adding that the retrofits target buildings "that are known killers. Complacency risks lives. One thing we can't afford to do is wait." The mayor's plan calls for thousands of wood buildings to be retrofitted within five years, and hundreds of concrete buildings to be strengthened within 30. The retrofitting requirements must be approved by the City Council, and would have to be paid for by the building owners, with the costs presumably passed on to tenants and renters. The costs could be significant: $5,000 per unit in vulnerable wooden buildings and $15 per square foot for office buildings, Business owners, who have expressed concern in the past that these kinds of programs may be unaffordable, said the cost of retrofitting some buildings could easily exceed $1 million each. "This will cost us billions of dollars in the private and public sector," says Garcetti. "But we cannot afford not to do it."
The last major earthquake in Los Angeles was the 6.7-magnitude Northridge quake, which killed close to 60 people in 1994. But it was not close to the catastrophe that seismologists predict if there is a major shift on the San Andreas fault, and the fact that it has not produced a major quake in recent years has fed a sense of complacency. Seismologists now say a 7.5-magnitude event on the Puente Hills would be "the quake from hell" because it runs right under downtown Los Angeles and have estimated that would kill up to 18,000 people, make several million homeless, and cause up to $250 billion in damage. "We want to keep the city up and running after the earthquake happens," says Lucy Jones aka "The Earthquake Lady," a seismologist with the United States Geological Survey and something of a celebrity in a city that is very aware of the potential danger of its location. "If everything in this report is enacted, I believe that L.A. will not just survive the next earthquake, but will be able to recover quickly."

Garcetti will have the undying love and money of builders and developers for years to come.
This will cost us billions of dollars in the private and public sector,
who is this "us" he is talking about? because with just a little thought, you quickly realized these "billions of dollars" are just transfers from the (assumed) wealthy building owners to the less wealthy contractors and workers.
one person's cost is another's paycheck and kids tuition payment.
if the public good is really being served here by improving safety of citizens, why isn't the discussion framed more along these lines?
never bring a twinkie to a food fight.
San Francisco already did this. Almost all the masonry buildings in SF have been reinforced since the 1989 quake, and now the rules are being tighened on wood buldings. If you've been in an older building in SF, you've probably seen huge diagonal steel braces. That's what it looks like.
All new big buildings meet very tough earthquake standards. The bridges and freeways have been beefed up in recent years. Overpass pillars are about three times as big as they used to be. Two elevated freeways were torn down after one in Oakland failed in the 1989 quake. The entire eastern span of the Bay Bridge was replaced with a new suspension bridge. The western span was strengthened, and there are now sliding joints, huge plates of stainless steel, between the roadway and the towers.
