What happens to Los Angeles when we survive the Big One but our buildings don't?
When the Big One — or even just the next Northridge-sized quake — hits Los Angeles, you will probably survive it. Between existing seismic codes for new construction and the ongoing mandatory retrofitting of concrete and soft-story wood buildings in the city of Los Angeles and beyond, most buildings should withstand a catastrophic earthquake well enough for you to make your way out of the wreckage when the shaking stops.
But those standards are designed just to keep buildings from collapsing. In a major earthquake, buildings could be so badly damaged that they are uninhabitable for months — or altogether beyond repair. With hundreds of apartment buildings, offices and supermarkets out of commission, Los Angeles would be a crippled metropolis. You think we have a desperate housing shortage now? Wait until an on the San Andreas fault.
In an effort to prevent catastrophic property damage, California Assemblyman Adrin Nazarian (D-North Hollywood) has introduced a bill directing the California Building Standards Commission to strengthen the building codes governing the construction of larger apartment and office buildings and some commercial buildings. Instead of being designed just to preserve the lives of their occupants, would require all new "engineered" buildings to be sturdy enough to function — perhaps with some minor repair — and be reoccupied quickly after a major earthquake. That means making them about 50% stronger than current standards. The new standard would apply to schools, hospitals and other public buildings only if it is more stringent than their current codes.
