mission bay and the city moving further south that is perfect timing i love the idea you have something circular and it will serve mission bay well and the cat elective too active the street life i know this is missing and the commissioner lives down there so the activity will bring it i have a couple of questions with the things 0 the left bridge i realize we're in an informational area i see this as a physical pitch point but on a warriors game day how can we manage the plan by both lanes on arrival time and escalators or sidewalks in both distributors i'm curious about the bridge at this point. >> thank you commissioner president wu and director ram

peter albert i know we'll have another opportunity to talk about transportation but first of all, when i came to you before about the waterfront assessment the green blue way we were looking at that it was actually an easy challenge at mta to look at the site in terms of the connection we've been doing that for a year and a half we're looking at the continuity of the embarcadero project it was underway at mta and separate bicycle investment sort out part of the infrastructure itself working with the street group and part of the combined events and the warriors i don't know if i want to try to talk about the details until we have the if you

recall plan conversation but maybe at a later date. >> i think as we go forward the other thing curious if there's a thought to the parking space underground on non-event days do 43 they really over and turn into office spaces and serve as double duty with the idea of maximizing our real estate resources. >> thanks for the question jessie with the warriors project as the gentleman said we're proposing to build 9 hundred restraining order parking spaces on site those are two levels below grade a sliver of upgrade parking is concealed so unlike mission bay you'll not see the

parking it will serve a doll purpose or multiple purposes frankly the operation mission bay your obligated to park one thousand per square feet so plus or minus the parking spaces they're dedicated but especially for those phases i'll august in the evening they're not utilized so they'll be available for public use then we have a dedicated portion of the parking for the arena and, of course, the retail a combination but the resource will be well utilized there is again synergy between the evening users coming to other retail on site it it will be a highly utilized asset and

obviously generate a lot of parking taxed for the city to support traffic. >> thank you one of the previous designs you saw of the ferry landing i realize it's shallow but i'm sure that's been a consideration. >> rick again high on the priority list a worries about not a reality the concept has been alive for access to the ferry something ucsf and the warriors are absolutely incredibly supportive together this will be a wonderful campus the right place and the sponsors obey talking about the extension he at the end of the 16th street which we think this is logical location for that but we've continue to have discussions it

is definitely on our wish list and will be added to the neighborhood and the project union thanks while you are up talk about the idea of maybe the multi used for the arena and treating it down for a sizeable event. >> we hope to program the arena on 2 hundred nights or days a year only 50 or so of the events a year will be the warriors the vast majority of other events will be for audience much, much smaller like 18 thousand one thing we've challenged the architects to do (laughter) is create a theatre within the arena that's much better and different in a facility of this type that feels like a separate facility but lighting a large

point and the seating configuration that involves walls and ceiling and also involves a different entrance we cut david short in his presentation but the entrance will be the theatre center lines that's meant to be our entrance for the theatre he events that will have a different personality in terms of the mralgz for sporting events and we envision about 4 thousand seating capacity the configuration and that will represent a great percentage of the events taking place. >> okay. thank you. >> one more thought sorry i think the images you've seen the helicopter voouz views from the bays are phenomenal and the softness of the arena is great

as most people will see this from third street i know the next phase an office building by you'll see a sliver so just give a little bit of thought to make sure they are just as beautiful and matching in contrast how you feel about you're riding our bike or walking down third street. >> thank you commissioner johnson. >> thank you very much yeah, i'm very excited about mission bay i like the design thirty 32 but i think this will add to the fabric of the neighborhood much more than thirty 32 with the great design and the southeast is definitely the location definitely exist a lot of my questions are really for the draft eir but i'll ask a

couple today a lot of times the eir is did not on whatever the project sponsor says and look at it at the environmental review but first a couple of accommodates i know that the architect mentioned he want to community meeting i don't know all the cacs in the city they're the hardest working i try to do what i can i don't see members here by the ocii staff katherine i know you guys work hard as well i go down fourth street a lot i like the orientation of the sites as you go down third or fourth it is rectangle in

it's presentation some of the streets are different whatever direction not only left or right. i like the fact there's an orientation on the site that's great my questions about the project ii know there's going to be a transportation management plan but i admire peter and all the work i want to ask you a question i notice in the report that we were given for today, the underground parking building didn't max out and allow for the urban building so something that occurred to me a couple years ago we were thinking about even the piers 30-32 site why can't he look at satellite parking facilities like the giant and

being able to develop lot a there's not a build parking lot just to have them and so we can look at other areas where there are satellite parking lot with the community arena so it this something you guys are caring. >> absolutely, in fact, you'll see in the presentation i want to hear the interesting idea working with the worries for instance, the idea of urging satellite parking using it strategically we interpret the drivers before they get to the heart of the arena by north bay to the north and south bay their intercepted and it helps to

balance the traffic you're right there's a tremendous amount of parking resources. >> thank you very much that's definitely i'd love to see in the either in the t mp or the eir other thing about obviously again schematics want to make sure that is a project like the giants stadium that will attract large-scale corporate events their letting people in on private tour buses that's fabric fantastic but i want to see where the tour buses have supposed to go and how that impacts circulation and pedestrian but also bicycle and car clarifications that's a question i'll be looking for that in the eir and i expect to see something there and i will just one more thing oh, yeah.

this is i guess more for looking at the design for the arena i know that architect and produced team do an excellent job of looking at the arena and the open space and it's orientation to more information on the site but you guys kind of answered a little bit of my questions i understand it is definitely considered part of the design and orientation but i'd like to see the voishldz and description especially the boulevard side of the arena month symmetric's say the streets the blue greenway i'd like to see that because that will give people a better opportunity to comment whether or not they think the orientation of that side of the arena works for the greenway and

where people are going to jump on and off not sure that rises to the level of something that needs to be called out in the environmental review report thank you very much >> commissioner hillis. >> thanks very much i agree with my fellow commissioners said but i think we agree that mission bay south needs help and can have a campus feel to it so i think it has a great potential of doing that i'm happy to walk through the ground floor it's incredible so it doesn't come across in the printed material as when you presented it so thank you for stressing that in talking about that in our presentation and hope you carried that to and the community and ocii are cognizant

of that ground floor moving forward so thank you. >> commissioner richards. >> i think it's at&t's an excited project it is much needed i think a lot of us do it right cities get it wrong they create dead spaces i like the food haul and the details of the park how much more can you ask for i think as the other commissioners said the user arena or from the air be fantastic architectures it will be great office design you can detract from the arena by putting office buildings there it's the same as everything else on the transportation i put back the envelope calculation on page 77 i looked at the transit

versus automobile mood split an event for the warriors regularly season of 17 thousand one hundred and 50 space there's a lot of overflow somewhere else and commissioner antonini. >> one final thought i think there will serve as a catalyst we have been looking at this site that moves people divisible from 16th street park a lot of the patrons coming from the south that will be a logical way to connect bart at that particular site it will take a while to do but enclosure that

as quickly as possible. >> commissioner johnson and one last point i wanted to mention in future presentations it would be great if you work in some of the work with working with the nonprofits and the services in the general area i know that the warriors organization has being been doing a lot of that in developing the agreement so it would be great to hear about some of the developments. >> commissioner richards. >> one other thing i forgot to ask he is passionate about her proposal is this something think the drawing board where do we stand in the half million secret of office space. >> the gentleman has been persistent ii assure you

there are probably dozens equally compelling presentations we're in the process of elevating them and it's a specific resource we'll - we haven't formulated our answer. >> thank you, again to the team for the presentation. >> commission will take a br k

break. >> good afternoon and welcome back to the san francisco planning commission regular hearing for december 18, 2014, i'd like to remind are the members of the public that the commission does not tolerate disruptions of any kind of any kind please silence all electronic devices that may sound off during the and and when speaking before the commission, if you care to, do state your name for the record. commissioners we left off under our regular calendar for the case the t third concept study an informational item and good afternoon. i'm nick i'm joined with bob macy's the senior engineer with the sfmta and our enter team person with the study paul will be giving you a

presentation the study was a growing interest under the connection subway from chinatown to fisherman's wharf and the transportation authority funded the study in march wear please be advised to share the results was an interagency effort we lied to acknowledge the excellent work i'm going to turn it over to to paul and bob i'm happy to answer any questions you may have. regarding mr. sanchez work on the project thank you. >> good afternoon commissioners we're pleased to give you a summary report as nick explained on the concept study and we will start off going into the studied itself

so look at the concept alignment we made decisions early on a limited amount of budget taking existing information and combine that together with that limited budget bring in help with consultants who have expertise outside of the 3 departments involved with that, one of the first decisions we want to keep the study looking at existing transit loimentsz figuring we didn't time to go into other areas so the alignments you look at are columbus with the stopping bus and united states powell street and beach street with the transit service on that out of those alignments we came up with 14 actual alignments implicit we will look at in a second so in addition to the two-way ones on columbus are back down up to the minute powell it goes

over beseech and one way loop alignment it connects the loop together all alignments assume the existing tunnels between chinatown and north beach will be used for some sort of service okay. next slide so the 14 alignments are many the 4 colors columbus and the loop is in light green all of them have a two or three stations not a requirement but that's how this plan was laid out and they looked at subway and surface this large number of alignments some under the subway and the subway in the first part and surfaced in the latter part excuse me. on this slide the initial analysis we found that two of the alignments were not feasible for construction purchasing purposes because of grade issues we're brent having

to do with getting the subway alignment around an existing very last year sewer that runs from the north point street a cross section of the entire area if you look at the upper right hand corner the triangle unfolded you see the different grounds types of that are out under that is based existing information and older information that came from the construction of sewer project i was talking about it is shown the circles to the blue rectangle and what this shows the subway alignment were to be built go deeper to get better ground it's a feasible use whatever term the stations open the northern end and the fisherman's wharf area is reviewing 50 feet of subway this

is an initial study next slide. >> two things to look at we had this in the report the issues of the facts of an earthquake and it lies with the factual area, no sense in hiding that the sea level rises by 24 med past embarcadero but for this project assessment those are not fatality places it comes close to a new project near the kicking land avenue this is similar like new york you can design you can design 8 features into a project to not make pa sea level prove but sea level resistant and travel time how

long will it take you look at the green box the faster from chinatown to the end of the line chinatown is the end of the phase two a little bit over 2 minutes on powell subway and the slower times are the surface ones that are roughly about twice as long if you do a one way loop in 8 minutes under the faster analysis and the advantage of the loop is the fact one the key issues in building an extension is turning the trains around and you still have to do lay over while they're in civil rights it is a cross over at the end of the line like we do on the other types of design the take away the subway is probably about twits as fast as a subway surface combo and the travel times if you look at the purple

box it's the existing thirty route from at&t park or caltrain station up to fisherman's wharf areas that's roughly thirty to 40 minutes the green line which will be phase two t third and potential phase 3 the running times are 14 to 17 minutes a little bit longer than for the loop twice as fast next one i'm going to turn it over to bob at this point. >> thank you. >> we'll turn on the milking for you. >> okay. the transportation authority lead the writing with the large improvements on the travel times it attracts a lot of rear view mirrors over 40 thousand additional trips on the t line that's is a 50 percent increase new riders to the muni

system so folks taking cars or not making the trips the remaining trips are from the tooift to the slower transit that existing e exists today it is a balance out of the overcrowded like the cable car and the bus one concern we had are ridership this slide shows the peak hourly load that explicit increase with the daily ridership that's due to the all day ridership that is attracted to the extension you see that the 3 minute head ways the upper red line on the graph is sufficient to support the capacity and the midline is running every five minutes by 20 thirty as part of the partner we looked

at the stationary so ems those are mature neighborhoods there are few soft sites within a quarter of a mile of the station nothing sizeable within the north beach station urging the planning department analysis the k340u789 be elevated it for property increases to fund the project they found that self tools to be able to use the bonds none are going to pay for it in full it will be 5 to 20 percent of a project depending on the configuration they also found with the limited number of development sites changing zoning limits or height limits will only have a modest effect on the revenue but that is the more important factor this is the capital cost our

consulting agents did the c ability analysis prepared a magnitude cost estimate from a national database and those are justified to 70s market there's in 20 to $14 not adjust for inflation still a useful tool for the concept you will notice the biggest drivers are the length of the limited and the number of underground versus the construction costs from hunters $.40 million up to billion dollars you'll notice the underground concepts are twice the cost of they're similar surface pairs and they're also about twice as fast there's a particularly situation going on there the

two-way extension along columbus avenue is $500 million for a parking lot surface configuration but $900 million for an underground option we took the option to e see how it compleets with other options it ranges in the cost effectiveness as defined by the sfmta that's using the fatah funding the first pathway the new starts program is a natural fit that does well, the land use will attribute some of the money and we'll expect to be using local like a prop c successor or some other will transportation revenue and there's room for

other outdoors idea like a violent development where that he partner with other agents to help to pay for the projects. >> with that, let me rupture it to paul to talk about the issues we have in our full report. >> one of the key issues is the north beach station and the palace sites and so there were people that said bore ahead and don't go take the machines out and what we found early on the vial that was done for the phase one and 2 wouldn't i couldn't be stretched to make it september to build a station like north beach it needs a new environment there are trafs
