>> so some of the details around the construction just to refresh your memories is we need to know what it will emancipation proclamation tail above and below the ground we have luxury condos on the east waterfront in almost 60 years that go up to 1 hundred and 38 floors above the ground. we were talking about the entitlements of the developer that received were typically - this will entail the taking down

of the building. and this is requires about 20 thousand 1 thousand dump truck trips over the seven months. now, what do sewer and eight washington have to do with each other. they have in common is the north effort main. the site is proposed to set over the cities largest sewer pipe. this is a pipe that my understanding is the 10 by 10 foot pipe and those pictures you saw earlier colleagues at westportal we're talking about a pipe this big (indicating). and we're talking about a pipe that was 19 inches big now imagine between me and i guess

that supervisor is 10 feet away from me imagine that pipe full of human wastes full of you know what. and this is a pipe that serves major parts of our city north beach our hills knob and services chinatown and in the maureen and i was told it also serves portions of supervisor kim's district in district 6. frankly everyone comes to work where everyone goes to show them o shop and tours in the neighborhood where 16 thousand folks a year flow through this area. next slide. so this is a picture of i'm sorry it's a little bit hard to

see. in the a map the eight washington site is to sit on top of the north forest main. there used to be a iron clad requirement the fact it's a called an easement of about 32 feet and as you learn today, our puc decided to give up this space and reduce the space so rather than 32 feet a little bit less than 6 feet. now you may wonder if there's construction next to this massive pipe of two basketball stadiums it might seem to folks there's a little bit of risk during the construction.

i may wonder since we're in earthquake county maybe a huge building hit that pipe. so those are some key dates of some of the documents we're going to be talking about about it today's hearing. the first two documents i think you're familiar with colleagues last year the committee approved the budget. and then early this year february 20, 2013, nothing has changed. now interesting enough there was a report that laid out the risk of construction and the future possibility of an earth quack

when was dated february 2nd, 2013, but the study but puc ambulance in july of the previous year and we have e-mails and letters i have documents at least between november 20th of last year and february 22nd there were conversations between the city staff about the concerns in this report. so this is a cover of the report and anyone that wants it can have it. but, of course, the devil is in the details and frankly the devil is in this report. next slide. so what i want to do is to ask two questions to city staff what are the real risks to the projects and the immediately

proximity to our projects and how could this not be included in the report >> i have a number of questions to go through. >> first of all, thank you for being here. i want to state at the outset truly i have respect for our cities work and we'll probable have some tough questions. so the first set of questions i have are really around what city sewer parts of the sewer system i understand you're the deputy for the puc what assets are around this area >> i'm the deputyen i offer se

operations for the power operations i do have is short presentation and a i'd like this to be a interactive communication. this shows the court property and the yellow is actually some of the easements we currently have and the red lines depict our sewer system. we do have quite a bit of infrastructure in this area that includes the jackson street sewer and as well as we have the north shore main that comes through this to our channel 3

division. and it's called a - it's being pumped it's under force this is one of our most important force >> how much force how many gallons of sewage per second. >> it pumps everything from across town. >> it's a 10 foot by 10 foot pipe? that's what i was told i remember when we had our conversation >> it's the jackson street box and that's the critical thing

we're trying to protect. we have both of those in play with the site >> brian anderson for the puc the pipe is in 36 diameter and it carries 20 million gallons a day. >> that's a lot of waste. >> okay. >> yes, it is. just checking >> go back to the presentation so just to let you know we have the jackson street box which is yellow running through the property that's where the 10 by 10 box. >> i'm sorry where on the map? >> it is running and it's no

yellow that's the portion of the 10 by 10 box that needs protection. >> so in other words that's underneath the projector we're talking about. >> there will be a 6 foot operation from the building and there will be a 3 and a half foot separation from a retaining wall to construct the underground parking. >> your puc engineers referred to the portions where there was a 4 foot distance between the the project. >> we're taking the conservative approach of 3 and a half feet. >> we're talking about the distance between i move and

supervisor campos between the building - >> between the retaining wall there's in another 3 and a half feet my but it's possible if something happened during the construction that could be at risk where the building could be shoved into the pipe. >> there are not redundant but we have work around these and under emergency situations we can move sewage around the city. you brought the second to lake issue that was an issue to us we were able to have it back into

serve service in about a week and a half >> i'm sorry you're talking about the issue of having it up and running. >> yes, we go upstream we block the sewer and take it down stream where it's effected. >> would you do it here? >> yes, we have the resources in place we're concerned about that and we want to insure not only for our existing consumers but for public safety that nothing happens to that sewer. >> and can you talk about what parts of the city does this serve how many households and people are using this on a daily

basis? >> 20 million gallons a day that's about a third. >> do you know betsy? >> project manager so this force main serves been 25 percent of the people and 75 percent of the. >> i'm sorry that leads to the 20 million glances of sewage? okay. than okay. thanks. do you want to continue? >> sure. so i wanted to talk about what we have there and we've been talking about that hopefully for the public those make sense and talking about what have happen

and then we'll talk about the protections we'll pit into place. to we have the easement to contain the north shore main and along what the things underground. and this is bringing the jackson street sewer down >> actually before you move off the sites can you hit the next slide i want to talk about easements. there's been an easements a 32 foot easements between the sewer system and anything else that's supposed to be built and we did a little research on this easement specific in the

documents it's for emergency vehicles. now the documents also state there's a restriction that property owners can't abilities above those easement nor use that that easement to damage the city structures >> now do you know when is permanent easements was granted to the city? is this a dive easement you're looking at >> i believe it's the drum street easement. indians that was an easement put in in 1964 >> so that easement wouldn't cover the force main where it cough.

>> telli m about the easement. and by the way, i have had a problem getting this information >> the 32 foot easement runs through the privately owned project that the former jackson street alignment. it's 32 feet wide and it is for public utilities and sewer. the infrastructure is slightly to the middle so there's 10 feet of the dissents to the edge of the easement currently >> okay. >> and is proposal so to shift it slightly to the north but to

the pucs approval. >> okay. and are there any restrictions on that easement? that you i'm sorry i don't recall. i don't think there are but normally under common law easement common law you wouldn't be permitted to build structure above that >> if those easements are approved then we actually would have the restrictions that you couldn't built on it the vegetation you could have on it. this is typical for our overwhelms and a lot of our easements are used for recreational purposes >> and i understand you can't build anything but the distance

we're talking about building and the sewer system is 3 and a half feet we're talking about. >> and that's the issue we're dealing with the developer on all right. go back to - we do have some facilities all right. there and lot 351 we don't have an easement for that but part of the development we would secure an easement. we also own a tell you block under the portion of the seawall block 351 and have a brainstorm pipe and this is the drum tree alignment that we own an easement along drum street.

and this is the proposed deposition of the existing facilities. we would actually have the easement shifted northward between the jackson street alignment and a new easement would be te this is allor existing facilities in place and we have the jackson easement where we replace some of the facilities. and then finally we'll vacant a portion of the easement to be replaced by the drum street easement above. so in consideration of that we're getting the easement back in perpetuity. i won't go into the project site buthi site being

the surgery is running underneath the park area running through the middle of the property cross the c lot 51 and that way. and you're correct in our project you talked about the 3 basement levels >> could you point exactly where that 6 feet is on the - >> so in looking at the north shore span he you see the red line dives toward the black line development on the side of the development that's where it would come within 6 feet of the force may that. >> and is 3 and a half feet?

my that's the jackson street box and the 3 feet is running there so the jackson - the shoring wall would be 3 feet and 6 feet away from that red line >> okay. >> so what kind of protections are we asking for first there's a pressure that the developer is responsible for any damage for the street. and in the proposed ordinance that's potentially before the board of supervisors is the fact that the developer and the puc need to enter into an agreement assessable to us and we would have a new easement in place for you know the existing work and

planned work we're planning now underground vaults to the area. the proposed utility agreement s from my liabilities and claims associated with this project. we've been drafting that internally we want to make sure that within the city family we can incorporate them into the agreement as we move forward >> can i ask a quick question? and you enter into the amendment with the developer and if the developer is allowed to sell all the condos the owners will pick up part or all of the liability? that you yes.

>> typically the case i have the purchase price so developer say gets toe a half of billion dollars and gets to walk away? do you know how these types of liabilities maybe taken into account. let's say someone buys a 7 and a half million dollars condo i assume that owner is responsible. >> it's a fairly board range to structure the deal to retain or pass along liabilities. >> would it be typical for a developer for years to retain

the liability if those units were sold off? >> i don't know if it would be typical i'm not a real estate. >> there anyone from the port to help us understand. assume there's an earthquake and all those units are privately owned who get to pass for the 20 million gallons a day >> it's not typical for the developer to retain the liability forever and assuming that, you know, we're looking at how to structure it to provide the maximum protection and in case there's a earthquake it

could be contributed to the design or other things and we're still working on that internally. but you're right it's not typical for a developer to retain liability forever >> i appreciate the fact you're familiar with the fact that the california teachers association is the partner in this. >> i've been told that. >> so they've invested $44 million into this and i'm wondering if anyone has talked to any of these folks. so during the construction some how the 3 and a half pipe area

gets broken? >> i'm not aware of any discussions. >> i think we may ask a representative to come to speak with us. >> it's not - we're talking about in the agreement i'm not talking about under statute or common law, you know. >> so if there's some kind of severe negligence. >> going back inform my slides finally there's the california civil code that the developer is required under the san francisco

building code to protection the joining land for any resulting damage so we feel that's one of the basis for us to go ahead and start developing the utilities agreement. we require that the puc review and proof the design of the shoring system and lay out the process for damaging facility in a way to identify the project in relation to damage associated with that. we would be allowed to recuperate our funds and we ask us to be indemnified for the facilities during construction activities >> and before we move on but i want to get a sense of the

exposure. how much would it cost to fix the damaged pipe >> it all depends upon how danldz it was and it could be as simple as million dollars dollars it's hard to estimate given that the size of the pipe and what we would have to go in and fix it. we have been going in all doing repairs and we're looking at replaying parts of the pipe. and we want to strengthen some parts of pipes >> how much are we investing in

those pipes. >> thirty million but that's going all the way from the south of marketing area. >> so i think i heard you say theirs multiple section? >> yeah. >> i'd like to get a budget open that. and we're talking about what the city minority on the hook for suppose this pipe bursts >> pumps out 20 millions of sewage a day how long

do >> we have
