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 break

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 tradeoffs for construction through the information a method that is less disruptive to the method and costs more another method slightly less but more disruptive the yellow t open the side that has another spur those are areas under the most disruptive design method you'll have to open up the street called cut and cover construction to put a station and tunnel and continual north the less disruptive will produce that by half the more disruptive is $400,000 and the less is still not cheap at $350 million

that is - i have issues this station is build by itself you'll need the turn around facility and at the end of columbus avenue you'll have a turn around facility the cost estimates is a turn around and plus you have to fully utility i utilize the tunnel they have no track to mta still holds an active lease on the property to remove. the t and the owner is prepared to go forward with construction on 19 unit at some point after the lease is over or it is removed early at this point our director ed reiskin said he didn't see a readily

easy way to acquire the site based on the fact it mta acquires property it can't acquire a piece of property and sit on it for several years and the funding is not available the planner as far as we've looked at this. >> next slide the summary elevation quickly of the 14 alignments including the two not feasible and on the left column it is small we came up with 7 different elevation kind of standards or elements realizing if there were done at the higher level it could change significantly but when it was done we looked at at a simple level zero means average and the subway alignment of columbus and pals us by the one we looptd

going all the way around to different streets and going lower with the surface alignments a couple of ways it was elevated we looking long term versus paying a little bit less up front but you have a issues of traffic and impact to the neighborhoods that's how we did that and lower lettering level the two lines are the cost in the report that come out creating came out 83 and at the bottom the higher the number the more or easier it is to constrict it is feasible but if it scored a 5 it looked like an easier job so this is our concept alignments to so you can see what we've been talking about xhumz u

columbus on the left and powell on the right and over in the one way loop so what are the next steps on the project okay. we're the blue arrow that slits off we're going to put out a final in january of next year and it is feeding into the transportation plan led by the transportation authority and feeding into a project that mta is working on with the strategy that is due out in the spring of next year the mta is looking at transit rail projects including the expansion and rehabilitation and upgrading the existing issues on the existing system they're all going to be evaluated so it selects which ones i guess the farther one side for future study that project is feeding into the core

capacity study of san francisco not only looking at the core issues but the train issues and and high speed rail issues they face to improve rails in san francisco that concludes my presentation. we're available for questions. >> thank you let's opening it up for public comment for public comment first and commissioners will ask questions. >> so if i call our name please line up on the screen side of the room (calling names). >> good afternoon, commissioners try with the fisherman's wharf community dignity on behalf of the cb d that supports the extension we all know that fisherman's wharf is an economic tourism attraction we attract thirty to 40 thousand people a

day this subway could be helpful i want to talk about other issue you may not be aware of our problems the retailer and merchant are having attracting businesses the businesses have lost 2 hundred and 51 employees he due to transportation issues 23 of the businesses shared their staffing levels and out of their 6 hundred plus position they have a lot of positions they can't fill because of the f line they find it difficult some people have quit and some people have been let go because they can't be on time when they having had experiences with businesses that are currently having a hard time filling their staffing levels with the

increasing rec driving people out into the suburbia people from the northeast part of the city this could be a god sent for fisherman's wharf our 6 hundred thousand hotels to moscone center but for the people coming in work with dialog right now with the matt with the short term swugsz we see the tooift as the best solution thank you for your time. >> at the. >> next speaker. >> good afternoon commissioner president wu and commissioners my name is bruce aim a member of the central extension sf next stop.org a rep for the south beach beacon hill association i

want to thank the team from the mta and the planning department for the excellent job on the study and supportive of their fthsd in addition to the ridership cost and benefits data highlighted in the presentation the central subway station with fisherman's wharf provides a connection on the eastern itself from visitacion valley to fisherman's wharf assess of progress periodic job applicant to jobs and resident to medical facilities to fisherman's wharf hotel rooms to the moscone center and provides capacity to meet latent traffic and reduce the congestion and improving the bike safety i - as the study indicates o a high cost

effectiveness for the fta finding that would be advantageous for the planning department having to identify opportunity tomato housing on under developed parcels this could repeal e hench the funding sources for the project it's difficult to increase the immensity in the areas specifically due to lack of transit capacity with the addition of the central by the way, there could be opportunity to contribute to the housing and jobs as island outlined in the planned bay area in addition as piloted the importance called out in the report for a possible future station entrance site and for construction assess in north beach i courage a targeted study to be initiated to identify
