Two L.A. City Council members are calling for their colleagues to back a statewide ballot measure that provides funding to cities for “earthquake safety improvements,” including helping property owners strengthen potentially dangerous buildings that could collapse in a major temblor.
The resolution, proposed Friday by Tom LaBonge and seconded by Mitch Englander, asks the City Council and Mayor Eric Garcetti to support or sponsor state legislation that would help fund local seismic safety efforts.
No such statewide measure exists, but LaBonge and Englander recently asked the city to report back on how the city could provide loans or help finance the retrofit of wooden apartment buildings or “soft” ground floors and older concrete buildings.
Los Angeles officials have known about the dangers of these buildings for years, but concerns about costs killed earlier efforts in L.A. to identify and force property owners to retrofit their buildings. Many owners say they shouldn’t have to pay for expensive fixes on their own. The costs of an engineering assessment of a single building could be tens of thousands of dollars or more.
Englander has said it’s unreasonable to create an “unfunded mandate” without looking into financial assistance for property owners.
LaBonge, who also submitted motions to look into cataloging the city’s old concrete buildings and wooden soft-story apartment buildings, has said a statewide bond program may be the way to help property owners finance the costly retrofits. “It’s a statewide issue,” he said. “Earthquakes have no borders ... we got to be prepared for the future.”
The proposals follow a Times report on concrete buildings that were built before 1976. By the most conservative estimate, as many as 50 of the more than 1,000 old concrete buildings in the city would collapse in a major earthquake, exposing thousands to injury or death.
Concrete buildings may look strong, but many older concrete buildings are vulnerable to the sideways movement of a major earthquake because they don’t have enough steel reinforcement to hold columns in place. Experts say sorting out which present the greatest danger of injury and death to occupants is a daunting problem that would require building-by-building assessments by structural engineers.
Wooden “soft"-story structures often are built over carports and held up with slender columns, leaving the upper floors at risk of crashing into ground-floor apartments during shaking. The 1994 Northridge earthquake damaged or destroyed about 200 of these structures, and 16 people died in the Northridge Meadows apartment complex.
In a separate proposal last month, City Councilman Bernard C. Parks asked that the city create a reliable list of older concrete buildings that need retrofitting and recommend fixes.
The motions will be discussed by a City Council planning committee this month, and the resolution will be considered by the Rules, Elections and Intergovernmental Relations committee.
