While BART’s earthquake safety program was designed to keep commuters alive, some sections of the system — including parts of the East Bay — are not equipped to keep the transit service operational after a severe quake, the report said. latimes.com/california/story… #ShakeOut

The report also identified more than 50 bridges at high risk for damage and collapse, and noted it could take three to 10 months to repair them. Many are along Interstate 880, a key artery connecting Oakland to San Jose; I-680 & I-580 also at risk: latimes.com/california/story…

Some areas in Oakland, Berkeley, Richmond, Alameda, San Leandro, Hayward, Castro Valley, Union City, Pleasanton, are at risk for having 20%+ of buildings suffer extensive damage. That’s a potential tipping point that may cause residents to flee latimes.com/california/story…

Old buildings = major risk. In places like Oakland, Berkeley, Hayward, Alameda, there are many "soft-story" apartment buildings, with flimsy 1st floors housing carports that can collapse. Old brick and concrete residential buildings are also a threat. latimes.com/california/story…

While Oakland, Berkeley, SF have passed retrofit laws for soft-story apartments, many cities have not, like Hayward. There could be a dramatic worsening of the supply of affordable housing if these are destroyed & not retrofitted before a big quake latimes.com/california/story…

What can be done? Communications systems can get backup power. Telling people to text, not call, post-quake could help. Also important to get more old homes, apartments, buildings retrofitted, and strengthen water/electricity/utilities latimes.com/california/story…

$80 billion has been spent since ’89 in the Bay Area alone on improving quake safety. But the East Bay has been overlooked. There has been 4 times as much investment on earthquake safety in San Francisco on a per-capita basis compared with the East Bay latimes.com/california/story…

Parts of Alameda and Oakland face risk of high liquefaction in a major quake. What can be done to make those communities more resilient?

A big flaw in Bay Area's planning is lack of talking about how to deal with vulnerable infrastructure regionally. There was surprise at how little communication had gone on between water agencies & firefighters in talking about lack of water after quake latimes.com/california/story…

San Francisco has a decent look at how long it'll take to restore utilities/lifelines. onesanfrancisco.org/sites/de… But what about the Bay Area overall? Wouldn't it be helpful for a region of more than 7 million people, to create its own lifeline restoration report?
