stay out of there and preserve it making sure that all of the pile driving and the concrete construction work and foundation work has begun on without damage specifically. >> as i mentioned previously quarters 10 was a residence for navy personnel and part of the vial documentation process it was deemed historic and now in the national register in late january we basically went ahead and relocated it quietly in the night down a windy narrow radio we had to do that to make sure there was no impacts a couple of pictures a large structure and now in place what's referred to as the clipper area

as also there's challenges that lie ahead and just want to list and go through them quickly our intent to complete the work by 2015 to make sure we have met the false work erection for this project san francisco bay bridge in caltrain it opening their new bike and animal facility and we're coordinating to make sure the bikes and animals are brought safely to the island franklin there's in an active construction zone in that regard there's changes to the sides and joint caltrain is requesting we're identifying those challenges and they have long lead items we have to get the final approvals quickly d b gold

compliance met the goal as i indicated and finally a reminder u.s. coast guard they have strike restrictions to stop traffic less than 5 minutes from any location so that concludes my presentation. on the ramps this is all the work that's going on on the east side of the island i want to shift to the west side of the island the west side bridges this is an aerial photos those are the brings that led to the westbound on ramp on the west side of the island as well as the are the tie into the eastbound as you're traveling from san francisco to treasure island that left off is right in this picture there

and what we have are 8 bridges that are symmetrical deficient and 5 of them will be retrofitted i want to talk about our preliminary efforts in the last few years. >> the soil there is it has issues there's unstable issues that is a helicopter view look ating the bridges there's been problems with the soil those bridges are old they're built in the 40s so in that regard i'll go through a couple of pictures to give you an existing condition of the bridges and let's talk about the concept we originally developed actually started in 2010

first step working through the caltrain progress for the federal approval those were prepared and approved in december of 2011 as i indicated previously we were going to replace 3 bridges and rieftsd 5 we've received the environmental approval in december of 2012 as we went ahead and studied did engineering in particular, the soil analysis we realized it was going to be an expensive project with an inherent risk it would require expensive construction and you see the steep hillside construction frankly when we started to we were the bidding

community we found that frankly not a lot of people want to bid this in terms of meeting the federal requirements we prepared the analysis because that project cost was something we wanted to see if we could lower and minimize the risk of construction and frankly, we've done just that we went to the analysis study that exclude the contractors as well as engineering experts they are recommendation to shift hillcrest road to the north and frankly push the roads into the hillside and build a tiered retaining wall this will approve the retrofitting and tida it will require additional jerry

and an environmental analysis but the good news we over all project cost lore we see it $66 million and we believe that the contracting community will be very anxious more of the contracts to bid the job just the pictures here show what's in right the shifting to the north this is a cross section showing where in essence we're going to build one bridge out of the 3 by shifting the roads into the hillside more retaining walls thirty to 50 feet high at this point. >> this is a breakdown of the cost overall for the project those basically are separate bridges in essence we're taking 8 bridges and working with the

state in terms of funding for each bridge individually and basically at the power point we have the fund and we're working with the future allocations for the major phase money and finally this is a breakdown of the federal funding $58 million plus from the federal 6 point one from prop b with the tida match approximately $3. million plus toy above extended $6.3 million on the engineering services and the environmental work also happy to report we're actually right now meeting the goal and take into account about a 14 percent for the are interim work we do schedule that lies ahead is to go ahead and perform the additional environmental analysis that is what we call

the new va alternative should be completed by march of 2016 and the at the end of 2016 to go ahead and start construction in march of 2017 to the important to needed we'll not start construction on the west side until the east side is done also conflicts reconstruction of the down and off-ramps on the east side of the island those ramps have been closed for a long time some folks may not remember they're there we'll complete by the spring of ri so we'll start in 2015. >> feinstein i've indicated challenges meantime you want to reopen documentation it is important to go ahead and do so and meet all the requirements of ceqa

san francisco puc is as busy as any agency they've been in their lifetime we want to make sure we gave me them early with the waterlines project and starting to evaluate alternative construction delivery methods that we'll see whether or not their feasible and bring to the committees and board in the future we learned add lesson on the ramp project is that the birds don't know what month of year when it's warm they start nest so we envision an early contract on the contract that was a delay because of bird nest issues that concludes my presentation. i'll be happy to answer any questions. >> thank you for you thorough

presentation. >> commissioner christensen. >> i was occurs about the aesthetic and environmental impacts of the two choices we're certainly seeking in the presidio a modern preference for low profile and integrated roadways so up until the parrot of retaining walls i was thinking the preferred approach would have visible and environmental improvements what happens to the sizeable retaining wall. >> the virtual impact analysis will be the key document we've prepare i'll envision there will be aesthetic treatments we'll have to implement has part of the project and caltrain has done similar retaining wall work on the one side of the island

and match the topographic. >> any other questions seeing none and i think tilly chang. >> i want to thank our folks and the entire yerba buena team this project a complex and in addition to managing the top graph and the actual job they've been able to corridor with the other promotions tida and others in the first phase of yerba buena housing and in addition the caltrain is taking down the bay bridge and we are coordinating with eric mentioned the mta and reporting with the touchdown of the bike and

pedestrians later this year i was pleased when a job like this is complicated and even in the middle of the night i want to commend them for a job well done we were on time and budget and continue to be on the budget. >> thank you and seeing no more comments from the commissioners all right. opening it up for public comment this was an informational item and next. >> informational item introduction of new items. >> seeing none we'll proceeded to general public comment any members of the public want to comment seeing none, public comment is closed. next item, please. >> item 12 adjournment. >> thank you. this meeting is now adjourned the inteblth is a huge

part of our everyday life everyone with the seniors use it for work and play. although there's a many valuable websites on line. >> the first thing a senior will ask me is about viruses if they go on websites what are the discharges of being on the

internet. >> for instance, you see something that maybe from the bank and the first thing it starts asking you for a private information where you get intiger's offers and they're not real. the way to tell where it's a fishing scam or not is who it's from. they can fake a name that says paypal but they can't fake an e-mail address it would be from a bank if they have any issue it's not going to be over an e-mail. >> stay away from e-mail all the same can be said on networking sites. the user should make sure they

know the person before clicking on the requests >> some of tracking software they can get argue bank account information some are more hamper full we'll get pop ups and i want to avoid those. there are many levels of protect your i s public works usually has a security looking for things you should have a updated advisor software. there are a lot of anti virus programs the number one free viruses program is microsoft security and microsoft has an invested interest for people to make sure their computers are safe purify you don't want to

francisco. we have 3 guest today. we have david constructional engineer and bill harvey. i want to talk about urban myths. what do you think about earthquakes, can you tell if they are coming in advance? >> he's sleeping during those earthquakes? >> have you noticed him take any special? >> no. he sleeps right through them. there is no truth that i'm aware of with harvey that dogs are aware of an impending earthquake. >> you hear the myth all the time. suppose the dog helps you get up, is it going to help you do something >> i hear they are aware of small vibrations. but yes, i read extensively that dogs

cannot realize earthquakes. >> today is a spectacular day in san francisco and sometimes people would say this is earthquake weather. is this earthquake weather? >> no. not that i have heard of. no such thing. >> there is no such thing. >> we are talking about the weather in a daily or weekly cycle. there is no relationship. i have heard it's hot or cold weather or rain. i'm not sure which is the myth. >> how about time of day? >> yes. it happens when it's least convenient. when it happens people say we were lucky and when they don't. it's terrible timing. it's never a good time for an earthquake. >> but we are going to have one. >> how about the ground

swallowing people into the ground? >> like the earth that collapsed? it's not like the tv shows. >> the earth does move and it bumps up and you get a ground fracture but it's not something that opens up and sucks you up into haddes. >> it's not going anywhere. we are going to have a lot of damage, but this myth that california is going to the ocean is not real. >> southern california is

moving north. it's coming up from the south to the north. >> you would have to invest the million year cycle, not weeks or years. maybe millions of years from now, part of los angeles will be in the bay area. >> for better or worse. >> yes. >> this is a tough question. >> those other ones weren't tough. >> this is a really easy challenge. are the smaller ones less stress? >> yes. the amount released in small earthquakes is that they are so small in you need many of those. >> i think would you probably have to have maybe hundreds of magnitude earthquakes of 4.7. >> so small earthquakes are not

making our lives better in the future? >> not anyway that you can count on. >> i have heard that buildings in san francisco are on rollers and isolated? >> it's not true. it's a conventional foundation like almost all the circumstances buildings in san francisco. >> the trans-america was built way before. it's a pretty conventional foundation design. >> i have heard about this thing called the triangle of life and up you are supposed to go to the edge of your bed to save yourself. is there anything of value to that ? >> yes, if you are in your room. you should drop, cover and hold onto something. if you are in school, same thing,

kitchen same thing. if you happen to be in your bed, and you rollover your bed, it's not a bad place to be. >> the reality is when we have a major earthquake the ground shaking so pronounced that you are not going to be able to get up and go anywhere. you are pretty much staying where you are when that earthquake hits. you are not going to be able to stand up and run with gravity. >> you want to get under the door frame but you are not moving to great distances. >> where can i buy a richter scale? >> mr. richter is selling it. we are going to put a plug in for cold hardware. they are not available. it's a rather complex. >> in fact we don't even use the richter scale anymore. we use a moment magnitude. the

richter scale was early technology. >> probably a myth that i hear most often is my building is just fine in the loma prieta earthquake so everything is fine. is that true ? >> loma prieta was different. the ground acceleration here was quite moderate and the duration was moderate. so anyone that believes they survived a big earthquake and their building has been tested is sadly mistaken. >> we are planning for the bigger earthquake closer to san francisco and a fault totally independent. >> much stronger than the loma prieta earthquake. >> so people who were here in '89 they should say 3 times as

strong and twice as long and that will give them more of an occasion of the earthquake we would have. 10 percent isn't really the threshold of damage. when you triple it you cross that line. it's much more damage in earthquake. >> i want to thank you, harvey, thanks pat for >> the renovation of balboa park the oldest in the city of

san francisco, and now it is the newest part in the city of san francisco. through our partnership, and because of public investment from the two thousand eight fund, we are celebrating a renewal and an awakening of this park. we have it safer, happier more joyous. >> 3, 2, 1 [laughter] =--[applause] >> it is a great resource for families, to have fun in the city, recreation. >> this is an amazing park. we have not revitalized it without public and private investment.

the critical piece of the process of this renovation was that it was all about the community. we reached out to everyone in this community. we love this park dearly and they all had thoughts and ideas and they wanted to bring their own creativity and their personality to bear on the design. what you see is what the community wanted. these ideas all came from the residents of this community. as a result, there is a sense of ownership, pride and responsibility that goes along with what is going to be an exciting park.
