sierra club i've been working on sf clean power for 2 1/2 years we dug up the petitions we've collected in favor of clean sf power we worked since 11 and 2 thousand plus handicap written letters and preservations from san francisco resident through the m and board of supervisors please launch this program that are a lot of people that are existed for having a clean energy option in san francisco audio wanted to celebrate the community involvement i've not seen this many people come to the sf meetings to speak for cleaner sf power for a long time thank you and especially coming out in the middle of the day people take a long lunch to make sure that the leaders what we want to see out

of the program i very much presenter our leadership and staff is city of chicago to the schedule but continue to hear from everybody what that he want to see community choice is a community program that's why we're developing this for the community and we want to make sure the community is involved and welcomed to be part of the process to talking about what neighborhoods should be invested in or where should we accredit the local entering we can hover local residents so they can understand the connections between the city investing in our city and where in their getting the energy from and this is a community development program that really helps san franciscans thank you so much for welcoming everybody i'm so

glad that folks from so many organizations and people are here to support that i hope we continue it is more of that we want this a community choice program it is for the community see you in two weeks. >> yes. >> as i'm sitting up here i know what it feels like to be in the audience we're advocates too right i don't want anyone to get the wrong idea i encourage everyone to show up if something needs to be repeated i encourage that i admire all the advocates they're willingness to exchange comments it is about good government and transparent and what you guys should be proud of what your overseeing and how your vaem and i don't think that

anyone this be disencouraged by the fact we're already there to commissioner caen's want i admire and respect and encourage it. >> i'd like to. >> yes. vice president you i want to express my prediction for everybody coming out the depth of the comments is not something we've seen on the issue at least from the r5ush8 and social justice and the neighborhoods to the lgbt community to the jobs peace and into the environmental components i feel liquor this as most people know many this program holds the promise of addressing so many needs of our community and city of the climate of the planet i want to

appreciate our voices and the time you've taken to speak before us. >> any fourth speakers topic mr. kelly. >> next topic mountain tunnel kathy howe. >> good afternoon, commissioners and commissioner president caen i'm here to talk about the work that the sfpuc staff has been doing with regards to mountain tunnel can you put up the slides? so i wanted to give a little brief view of where mountain town hall is it conveys water to other power house and extends from the dam to the reservoir and it was completed

construction was completed in 1924 and it is approximately $19 million long we will be talking about the portion from peace portal to south fork east and to give you an idea this is what the tunnel looked like at the completion of construction in 1925 with the concrete liner and this is what it looked like in the detailed inspection in 2008 and what you see here is e restoration of the concrete liner so in terms of what we're doing we currently have 3 components there is the access improvements but first i'll define what a failure of mountain tomb is

since everyone oh, a failure what's 0 going to happen it is a loss of approximately 20 to 22 percent of the carrying capacity so e restoration will continue over time we need to take care of repairing that liner the purpose to mitigate or reduce the loss capacity so the 3 components are added assess improvements and the emergency restoration and the mountain tunnel repair and, etc. >> the added emergency restoration involve enlarging the opposite at 56 theirs 5 feet in dinning room so we want to

get heavier equipment to remove collapsed material within the tomb and working on implementing the emergency restoration in december 2014 our consultant lack and beach come up with a restoration plan we're in the process of implementing that plan that provides for on call contractors having materials stockpiled and having the materials and equipment crews ready to remove debris that falls into the town hall and so the goal definitely is to be able to return service of mountain tunnel within 3 months following a failure of or collapse of debris in the tunnel

it would take 6 to 9 months to roars the tunnel with the prelims of the emergency response plan we should be able to complete that debris remove in months time. >> so can i ask a question about the emergency restoration plan that is something we've not talked about before; right? >> we've not talked about it before. >> and is it really about debris kind of to get an understanding of debris mauling falling into the tunnel. >> it is about debris falling into the tunnel large debris blocking the water flow so the water flow is reduced by 20 to 24 percentage right now they're small in size the only thing you can get in there is the hand

equipment unless we use the portal. >> what if the big one hits tomorrow. >> it will not hit the next day or 3 years. >> we had a path review and the technical stewart's experts say it's an e restoration of the soil. >> it may be a good bet to take you don't know when the next big one will happen but we want to make sure that those improvements had is there in case of an emergency to repair it if it is partially collapsed are debris get in there we can remove the debris and bring that

back into service that's the most important thing we want to do if we have to do a bypass tunnel it takes a long time that's why those presentations we talk about the first component is making sure that something happens between now we do anything we have the ability to repair it and bring it back into service. >> so this is not replacing the replacement of the town hall. >> no, no so this first part of the component she's talking about is getting access to the town hall is just you know allowing us to have better assess to the tunnel just in case we have large equipment to remove debris and plus kathleen is talking about a plan in place

with equipment on stand by and everything necessary to do the necessary you know repairs or go in and remove debree we needed a plan in place we have that plan and moving forward on the project. >> on implementing that plan. >> so where does the water go during the 3 months. >> it basically wouldn't have to be shut down we'll be getting local supply. >> i want to add to that because that's. >> steve richie assistant general manager that's the crux of the issue it is 6 to 9 months that mountain tunnel can be out of service that supplies 3 months or less is something we think t is manageable from our

reservoirs so a months back in service timeframe our systems what handle again using crystal clear springs and calaveres and other local reservoirs and the enter ties we can continue to provide service. >> all that water would have to be treated and yes filtered. >> we have the capacity. >> yeah. at the harvey treatment plan and others plants we will have the ability to treat that water and delivering it to our customers. >> okay . >> so back to the first component the construction documents should be ready for advisement by the end of this

calendar year 2015 and holy shooting for construction by mid 2016 with completion of the added access improvements in the spring of 2017 so with regards to the mountain tunnel - inspection and repair we have also scheduled a 2015 inspection to update the condition ascertainment and have planned as well in our schedule to do repairs in 2015 and 2018 reason we're not doing the inspection in 2016 is because we

basically need to two year advance notice for shut down longer 10 days so if we did a shut down of 10 days it won't give us a sample of the closer liner we would like because the 10 days includes the inspection and bringing service back on so the actual window for inspection is 45 days withhold to do a thorough inspection similar to the one in 2030 that's why would he have scheduled the shut down for 2017 why can't this be done together we're talking about years not months beyond why we go to2017 we

have to give the fish plant we've missed the two year window for longer than 10 days. >> the other thing authors only a certainly period of time we can have a period of shut downs that's when the demand is not as how around january we can actually shut down the system for an accelerated period of time if we miss one shut down we have to wait to the norwalk. >> you have the same question isn't there a way to get a waiver to declare a state of emergency. >> it takes a lot to shut down the system and what we felt was that we wounded do any repairs no way because we don't have the

contractor on broad so we felt that why don't we wait until the following year we can actually do repairs but go in there and do an ascertainment of the tunnel more robust ascertainment as we go into the presentation it was a question about the 2030 ascertainment we've had you know technical advisors panel and they looked at the same information and had a different opinion so we really want to do core samples and do aggressive we want to - with the most accurate information to determine the best solution we'll go in more details to answer our question is that we wouldn't do repairs anyway until 2017 and we're planning to do

that. >> we couldn't do repairs in 2016. >> no way. >> steve you want to - >> you want to - >> oh, what we're talking about isn't something in the not a walk in the park it is a major undertaking the close tunnel inspection just the inspection took a year of preparation to get it done right and effectively to contract and have good data from this doing the repairs we have to design the repairs i think we use the word patching this is noted poaching up the lines this is not a spectacle this is a concrete snauks several thousand of feet into. >> tunnel those are huge flaikz

those are not simple if you're going to do it right it is easy to get inside a tunnel and get out you have to be safe and thorough about it really an under taking it takes years to do it right and the 2030 inspections we did was a very good one only after the 2018 inspection and didn't do it as well as we could by the time but needs to go back in 2008 they're a huge undertaking. >> they're currently the size of (inaudible). >> so the amount of you know people and equipment you can get

in it limited in a short amount of time so the first bunch of work to open up 9 assess point to you can get trucks in once you have a that capacitate you'll bring in the inspection equipment that's more o more sophisticated so to open up the tunnel once this is done it is easier. >> i understand the i am peril timeline how do you force rank in projects like this for the water system improvement program is there a scale in prioritization. >> for the water this is the number one priority that we're working on we know that this is the lifeline to the water system we worked on all the water system

improvement programs but recently, we had a report by urs this is an image it is not necessary danger we had the panel look like it and their opinion was different. >> i was going to say the one 33 we thought was the seismic risk now we're lookout mountain tunnel the next priority. >> we're not going to build a new tunnel. >> so basically for the inspection and repair we're looking at january through march for inspection and repair and doing repair again in january through march of the following year and the estimated budget for this is two to $25 million and so we also at the same time

hired urs to develop alternatives they've developed alternatives we hired a technical advisors panel that came back with suggestion for repair and the alternatives were reevaluated and so what i'd like to pout the steering committee everybody got exist with the last issue that the tunnel was the best alternative the stooeshg likes that alternative everyone concurred with moving forward with the hiring of a consultant we wanted to do to provide assistance to perform the inspection and design the repair as steve mentioned its national a patch job so defects requires design we'll get a

xhourlt we'll be completing planning or conceptually engineering but with the information we gathered from the inspection in 2017 and with the repairs in 2017 we'll be back to the stooeshg and the commission as well with this information and the recommendations those recommendations could be we continue with the robust repairs into two or three more shut downs and build a chauvinist for easier assess or come back with the repairs or a combination of a tunnel that's $12 million or miles or shorter we'll provide a scalding schedule with all 3 components with mountain town hall to get a picture of the schedule and the budget for all

the activities i've talked about. >> commissioners. >> one question is the portion of the recommend work that is like i said, we have a portion of the work involved in 9 conceptual design of a bypass tunnel how much. >> i don't have that fought off the top of my head but i'll get it to you. >> 6 hundred. >> 680 i think is the total. >> that's the the way we do the bypass tunnel but a step we're doing the inspection and repair. >> right so you're looking for we're doing the conceptual engineering may not be our final recommendation so the question how much does that cost. >> typically on the water

improvement the water design is at risk we did a lot of designs before we got the second approved so a lot of it was at risk this is a similar that we'll hire the consultant they'll be on broad by the time we have more information hopefully, we'll make a decision before we go too far along the design. >> we'll not be getting into the design it is still considered planning for the go designing but coming back to the commission you have a comment. >> i do have a comment i'm totally not able to conceive of the scope of all this but it seemed we're doing work that we

might end up undoing total completely i see the figure out here. >> where you're doing the environmental review or the tunnel are repair to start of the environmental review repair is not wasted work and the conceptual engineering work done for a by a pass is not that far in advance and relate to how much the construction costs you'll not be spend a large percentage until you get into design okay. so it comes after your slide 11 where you have the estimated budget of 2 to o to 25. >> for the rarptsz in 2018.

>> so the one thing we need to do the repairs it doesn't matter whether we had a bypass or not to extend the life just in case something happens we need to do the repairs no matter what and the main thing if the repairs hold up well as we do more dwindling down to see they last a very long time with that information it will help us to do the decision of the bypass of the repairs we perform are in good shape because it is be unnecessary that is why it is important to do the inspection through the core samples and start with the repairs once we go back and see how the repairs

are formed it maybe unnecessary to do a bypass or identify we don't have to do a 12 mile by basis psa but a two mile bypass we want to find out that information but no matter we're planning over and over on making repairs. >> okay. i hate to keep on pregnancy this you're the expert i certainly am not but the year 2018 that's 3 years from now before we have my answers. >> no 2017 we will have answers. >> it says 2017 and 2018 to elevate the risk of collapses. >> in 2017 we'll start the repairs and 2017 we have the inspection on the liner and the lot mass behind the liner. >> so maybe this will help

so let's say we have to do the bypass tunnel it will take what's the date on the by past. >> until 2025. >> until it is complete that medians we'll be working on the bypass tunnel until 2025 therefore we need to keep repairing the existing tuesday night that we shut down okay well, this is just a report perhaps we should talk so you can better inform me i don't want to waste time with this talk i'm not educated on any other comments commissioners? okay. thank you very much oh we have speakers >> nicole.

>> good afternoon, commissioners again nicole ceo for bosco i'm pleased you got this report as you know we're concerned about the water supply source to the townhome and in march i asked this commission and that this commissioner provided a comprehensive plan and i do welcome the presentation you received today and certainly welcome our questions i appreciate those i don't think what you got was that comprehensive plan schedule it didn't give you the bosco that the users the confidence this will be fixed but i have 3 specific comments first the presentation references the emergency restoration plan i mean, i requested this in january 2014 my first reaction

from mrooesh what do we do until we get it fixed 2025 is a long time i received a copy of the plan but completely in december we're going to be receiving the document to see if it provides specific action and the urgscy to minimum plaintiffs misses the threat from water supply due to the failure of mountain tunnel i support of the second time they provide a necessary first step nothing can be done with the access you have right now but i'm looking at the plans and couple of questions keyed in on it does that emergency plan address the impact towards supply current with the way the current system mrooesh said 3 to 6 months and with the
