have pictures that are really telling the story bridge d the westbound off-ramp is false work is being erected and happy to report we've moved the west building i'll have more and right now, we're on schedule to complete the project by august of 2016 just some pictures i want to go through quickly westbound as i indicated this is in essence if you go to san francisco from the island this is the point to merge on the concrete area and the light poles will be relocated to the right we bridged that that's good news in that regard this is me stand on the what is referred to bridge 60 feet up in the air this looks at identically point to the new

expansion this is the largest bridge out of the 5 and is at a point to go ahead and build the bridge deck it's a c of climates out there now as you can see basically that is a bridge looking east showing the column work that's completed and this is a one of the final pictures i have just the columns behind the area the entire area referred to as quarters one is historic so bottom line we need to 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

>> what if you could make a

memorial that is more about information and you are never fixed and it can go wherever it wants to go? everyone who has donated to it could use it host it share it. >> for quite a great deal of team she was hired in 2005 she struggled with finding the correct and appropriate visual expression. >> it was a bench at one point. it was a darkened room at another point. but the theme always was a theme of how do we call people's attention to the issue of species species extinction. >> many exhibits do make long detailed explanations about species decline and biology of birds and that is very useful for lots of purposes. but i think it is also important to try to pull at the strings inside people. >> missing is not just about

specific extinct or endangered species. it is about absence and a more fundamental level of not knowing what we are losing and we need to link species loss to habitat loss and really focuses much on the habitat. >> of course the overall mission of the academy has to do with two really fundamental and important questions. one of which is the nature of life. how did we get here? the second is the challenge of sustainability. if we are here how are we going to find a way to stay? these questions resonated very strongly with maya. >> on average a species disappears every 20 minutes. this is the only media work that i have done. i might never do another one because i'm not a media artist per se but i have used the medium because it seemed to be

the one that could allow me to convey the sounds and images here. memorials to me are different from artworks. they are artistic, but memorials have a function. >> it is a beautiful scupltural objective made with bronze and lined with red wood from water tanks in clear lake. that is the scupltural form that gives expression to maya's project. if you think about a cone or a bull horn, they are used to get the attention of the crowd often to communicate an important message. this project has a very important message and it is about our earth and what we are losing and what we are missing and what we don't even know is gone. >> so what is missing is starting with an idea of loss, but in a funny way the shape of

this cone is whether you want to call it like the r.c.a. victor dog, it is listen to the earth and what if we could create a portal that could look at the past, the present and the future? >> you can change what is then missing by changing the software, by changing what is projected and missing. so missing isn't a static installation. it is an installation that is going to grow and change over time. and she has worked to bring all of this information together from laboratory after laboratory including, fortunately, our great fwroup of researchers ers-- group of researchers at the california academy. >> this couldn't have been more site specific to this place and we think just visually in terms of its scupltural form it really holds its own against the architectural largest and grandeur of the building. it is an unusual compelling object.

we think it will draw people out on the terrace they will see the big cone and say what is that. then as they approach the cone tell hear these very unusual sounds that were obtained from the cornell orinthology lab. >> we have the largest recording of birds, mammals frogs and insects and a huge library of videos. so this is an absolutely perfect opportunity for us to team up with a world renown, very creative inspirational artist and put the sounds and sights of the animals that we study into a brand-new context a context that really allows people to appreciate an esthetic way of the idea that we might live in the world without these sounds or sites. >> in the scientific realm it is shifting baselines. we get used to less and less, diminished expectations of what

it was. >> when i came along lobsters six feet long and oysters 12 inches within they days all the oyster beds in new york, manhattan, the harbor would clean the water. so, just getting people to wake up to what was just literally there 200 years ago 150 years ago. you see the object and say what is that. you come out and hear these intriguing sounds, sounds like i have never heard in my life. and then you step closer and you almost have a very intimate experience. >> we could link to different institutions around the globe maybe one per continent maybe two or three in this country then once they are all networked, they begin to communicate with one another and share information. in 2010 the website will launch, but it will be what you would call an informational website and then we are going to try to by 2011, invite people to add a

memory. so in a funny way the member rely grows and there is something organic about how this memorial begins to have legs so to speak. so we don't know quite where it will go but i promise to keep on it 10 years. my goal is to raise awareness and then either protect forests from being cut down or reforest in ways that promote biodiversity. >> biodiverse city often argued to be important for the world's human populations because all of the medicineal plants and uses that we can put to it and fiber that it gives us and food that it gives us. while these are vital and important and worth literally hundreds of billions of dollars, the part that we also have to be able to communicate is the more spiritual sense of how important it is that we get to live side by side with all of these forms that have three billion years of

history behind them and how tragic it would be not commercially and not in a utilitarian way but an emotional emotional, psychological spiritual way if we watch them one by one disappear. >> this is sort of a merger between art and science and advocacy in a funny way getting people to wake unand realize what is going on -- wake up and realize what is going on. so it is a memberorial trying to get us to interpret history and look to the past. they have always been about lacking at the past so we proceed forward and maybe don't commit the same mistakes.
