you may remember this scene from the loma prieta quake. 220 ton section of the old bridge collapsed. traffic came to a halt for over a month. how big of a danger zone is this? >> it's a major one. >> how close are we to one of these faults right now? >> we are very close. the hayward fault runs right along the hills. >> the bay bridge is a stunning engineering feat for another reason, something that's not visible at first glance. crumble zone technology. until now, crumple zones have been used by cars. they control deformations. the old bridge won't collapse even in a powerful quake, engineers say. marwan was a engineer during the last quake. being. >> if you want to be if a big quake hits? >> the safest place will be on the top of this bridge. it would be one heck of a joy ride but it would be a safe one. >> this is how nadir are describes this, the engineering community considers this be game changers. the first one is the sheer link beams, inside the 525 foot tower. >> the sheer link beam is the heart and soul of how we made the single

you may remember this scene from the loma prieta quake. bridge collapsed. traffic came to a halt for more than a month. how big of a danger zone is this? >> it's a major concern. >> how close are we to one of these fault lines now? >> we are very close. at the eastbound hills, the hayward fault runs right along the eastbound hills, near the bridge sits the san andreas fault. >> the bay bridge is a stunning feat for another reason. something that is not visible oat first glance. crump crumple zone technological. the new bridge won't -- technology. the new bridge won't crump crumple. >> where would you want to be if an earthquake hit? >> on the top of this bridge. it would be one heck of a joy one. >> this is what nader is talking about. the engineering community considers the innovations, game-changers. inside the 585 foot tower. >> the sheer link beam is the heart and soul how we made the link work. everything is ealas tick. >> this animation allows the four legs of the tower to move independently. >> the stiffer the structure, the more ri

there was staff when loma prieta happened and there were deaths down at bluxome a block away. people, this is not solid ground. it's marsh. i want to talk abut the jobs and the housing ande affordable housing prgram. you have on page three of your report with the trsit impact development feeand all of which is instrumental in tting passed in this big struggle in the arly s. they are getting credit for demolishing tdr. there is no way about this. look this. office developmenpas $13.21 and they are getting credit for demolishing. r it was the building. this was a t-shirt factually.but they get credit othat whicis worth $11.7 from t idf and $17 credit for south linkage. if the planning department doesn't say, hey, they are losing pdr and we should consider whether they should get credit for demolishing pdr on transit fee and housing fee are not doing their job. why should i be their only one who reads these and telling you what this is. i'm telling you this is wrong. >> thank you. any further public comment? seeing none, public comment is closed. >> commissioner antonini? >>commi

i remember back in '89 -- excuse me -- the earthquake loma-prieta earthquake and, boy, there's somethingut an earthquake that really gets your attention. i remember the a's and the giants were playing and all of a sudden, you know, god magnified that and we instantly around the world realized we were having an earthquake. i was listening to barbara shim on kfo 560. if we have an earthquake, the new bay bridge is built -- the entire thing comes down. and i don't know if we can do anything about that. but back when we had the quake back in '89, we just had a section of the bay bridge fall down. evidently because of the, you know, all the money involved [speaker not understood], they have their wicked for to bush and policy over there. there's a lot of money involved. it's difficult to stop a project, you know, when so many people are benefiting, you know, by it. i guess the new bridge is, according to barbara simpson on [speaker not understood], you can ask her about it if you think i'm giving you false information. hopefully we can go back to the other bay bridge because [inaudible]. you
