>> welcome to land use. i am sophie maxwell. i am joined by supervisor mar. our clear is alisa. i believe you have some announcements. >> please turn off also phones.

documents should be submitted to the clerk. documents will appear on the other agenda unless otherwise stated. supervisor maxwell: do we have any additions to the agenda? madame clerk, are there any committee reports? >> in no. supervisor maxwell: please read item number one. >> hearing on the city sewer improvement. supervisor maxwell: a call for the hearing because there has been a process going on regarding our sewer plant. it is way overdue for more than repair. it may need replacement and looking at the next 100 years forward. we have had a number of people charged with looking at placement and maybe some other things.

before we go any further, and want to thank all of the people who participated in this. i want to thank you over and over again for doing your civic duty and your responsibility to the people of bayview and the people all over the city. thank you very much for that. i would like to ask for the departments to come up. we can then have the members come up and talk about the process. >> i am karen kubick. we will be focusing our presentation on the process. i also want to tie it to the overall improvements. i do have a presentation.

what's see if we can get that up. -- let's see if we can get that up. supervisor maxwell: before we go any further, i want to say, " doh, the giango, giants!" i do want. knowledge we have members of the task force with us. please stand up so that we can see you. thank you, espanola. karen pierce is here as well. thank you for coming. i want to acknowledge someone i have known for 25 years. virginia homes is also here.

the moderator, mediator, chairperson for the task force is here. thank you, i know you did a great job. >> i am going to be talking about the source system improvement program, focusing in on the changes we seek and the work that the task force did. we will move forward to the next steps. hopefully at the end of the presentation, the task force members will be able to share some thoughts with you. the source system improvement program is our capital improvement program for the waste water system as a whole. much of the emphasis will be focused on improvements at the southeast. we have developed a report. we have had an extensive planning process of about five to seven years. we recently committed --

completed 7 workshops where we established levels of service and goals for what the new system would look at. the major findings are on the web. i am hoping we can discuss a the next briefing the goals and levels of service and perhaps seek endorsement from the board. this summarizes the improvements will be making over the next 30 years. the levels of service are to provide a reliable and resilience system that can respond to catastrophic events, provide benefits to impactive communities, modify the system to adapt for climate change, and achieve economic and environmental sustainability. supervisor maxwell: i am sure you are planning to do that through innovation and in for sharp sure -- infrastructure. >> there are different processes that will have smaller

footprints and the more energy efficient. we can take the waste into something positive come either re-entered -- energy corporation reusable products. that is where we are. supervisor maxwell: is that 30 years going to take us -- the systems all over the country were done many years ago, almost 100 years ago. the things we're going to do, are they going to prepare us for the next 30 years? >> that is the plan. we would be looking at the effects of climate change in the future, the standards we know about. any standard requirements or changes to the city we would want to address for this implementation program. the projects are summarized on the map. we will have upgrades to each of the treatment plants.

there is a tremendous amount of work that will occur in the southwest district. we will be upgrading the treatment plant. these upgrades are visual. we want to get the process to be the most modern and energy efficient. we will have outflow and alcohol rehabilitation. there will be a natural treatment plant at treasure island. there will be upgrades to the north point facility. we have a lot of wet weather improvements. those include low impact design. we talked about that at one of the previous hearings as capturing storm water, holding it locally within a drainage basin, and then reusing it for beneficial uses. we have several flood control projects throughout the city. we have one major tunnel project that will go from mission creek. right now, we have an asset that has been in place since the

early 1950's. it has failed during lomo prieto and four times since then. we expect to see the sea level rise and reduce flooding in the mission creek area. we will get more of the waste water collected and treated at the new plant. supervisor maxwell: the mission creek area is where? >> channel and division streets. the channel st. paul station is there. there are new condominiums. -- the channel st. paul station is there. there are new condominiums. there's a lot going on in that part of town. there are other major projects occurring in the same area. supervisor maxwell: the mission creek flows into the bay? >> the flows come from north --

tommy is saying it might help people if i say the cove. i am new at baseball. it is bringing flows from the north, down around south, and then to visit to the treatment plant. we also have some flows coming from the south to the north. we're most concerned about what weather clothes and sanitary flows and making sure we have a reliable piece of infrastructure. it is one of our more critical pipes because it is under pressure. most of the other pipelines are gravity flow. supervisor maxwell: at some point, there was a creek. i assume it went into the bay. >> at one point, it did. a lot of the edges were filled in. as the city developed, it got wider.

we're working on laying out a timeline for all of the projects with the out front ones being the digesters. it is highlighted here. it is in the southeast. we will have ongoing projects. we have pump stations to start right away. we will be returning to you with information about contracts we will need to support these efforts. the main one is the project management contract. is similar to the water supply to upgrade. we will be looking to get a program manager in at this location. through our hearings with the commission, we have been discussing projects. we've been looking at timing and levels of service. the program will cost between $5 billion and $7 billion over an extended period of time. we will be seeking outside

sources of funds to help with the burden. nearly half of that money will be focused on the south east digesters, the channel tunnel, and the other improvements that will occur at the water pollution control plant. the real focus today is the digesters. a lot of our discussion is talking about treatment. we treat all of the storm water. we treat the waste water. we handle the solids. this is our se water pollution control plant. along the north, where bordered by the elevated lines. we have third street and evans down here. that may be a landmark that is more familiar to people. it runs to the ballpark, i believe. the digesters are located here on the south side of the plant. there are 10 currently. on one of them, the roof has

fallen in. they were established in 1952. they do not meet current standards and are past their useful life. this is a project that has got to happen. we want to do something that is right for the community. we want to put it in the right place. we want to make the right decisions. this will be in place for the next 50 years. it is really a legacy that will be part of the waste water program. currently, the facility does not meet the standards we anticipate in the future. it does not meet the high level of standards for by a solids -- bio solids. the next slide shows when one of the roofs fell in in 1996. recently, we nearly lost another

one. if we lose another one, we will not be able to be in compliance with the facility. we will have an emergency on our hands. it is due to the good work of the maintenance people. there were able to save it, catch it, and repair it. the digesters of the most maintenance-intensive process at the treatment plant. we have nine in service now. we have the original 10. we lost one with the roof falling in. every year, one of them is cleaned. the material on the bottom as all of the sand held there. it is because of the old design with a flat bottom. will not have sufficient restraints or anchoring to withstand any seismic action. supervisor maxwell: explain to people who may not understand what happens in a digester. do you want to do it later?

>> the digester does for a treatment plant what your stomach does for you. it does produce certain gases. [laughter] actually breaks down the organic material inside. it breaks into gas and water. supervisor maxwell: where does this and come in? >> we have a combined system. if you take a garden hose and spray it on asphalt, and has sand. it goes into the sewer and conveys to the treatment plant and insect in the digesters. supervisor maxwell: supervisor mar? supervisor mar: what is the difference between the digesters or stomachs in oceanside versus the bayview hunters

point ones? >> it is an egg shaped digester, a sealed vessel. the one in the southeast has a floating roof. we get emissions. as tommy put it, there are issues. supervisor mar: some of the other ones are over control. it seems it would negatively impact the communities around it in residential areas. the odor control is related to not just the digesters but the rest of the renovations going on? >> we would be putting in new air treatments and handling. the objective is to not have any odors at the treatment plant and have any odorous processes set back from homes as far as possible. supervisor mar: thank you.

>> another big distinction between oceanside and southeast is that the oceanside plant was designed for the maximum earthquake on the san andreas fault line. the plant on southeast is on bay mud. we could easily have a failure at southeast. it was not designed for that type of thing. moving on to the next one, i want to talk about the land required for a new project. a lot of time was spent looking at sites in talking about property. the area needed for the digesters for the bio solid treatment is about 10 acres. the digesters themselves take up the footprint of about two acres. with the water and gas storage and capturing the gas to create screen power -- we can use the green power on site.

we have a generation system at both sites. we want to optimize the power and have more green power that can be consumed at the plant. supervisor maxwell: is that is what we're calling resource recovery? we will recover and use them? >> we will look at the best and most cost-effective system abuses of the gas -- uses of the gas. in other places, it has been looked at for vehicle fuel or put back into the natural gas system for the city. we will look at all those things in terms of cost and life cycle. an additional 5 acres would be required in the future for drying if we were to move towards that. that would be using solids locally within the city. several of the task force members have a lot of interest in that. they want that for their

gardens. this is something that we will have lots of meetings in the future about. the digesters themselves with the approximately 60 feet above grade. that is about the same height as the other structures at the southeast plant currently. now i want to talk about the task force itself. then we will get into some of the specifics on the siditing. members were recruited through a process. we went to local community groups and asked people who would like to participate in the critical project. we got some volunteers. we have individuals representing the southeast community commission, bobby brown and helen yang. the chair of the waste water subcommittee michael hammond, virginia holmes, the owner of

pet camp, and ms. espanola jackson. the task force was very diligent. they volunteered their time. the net monthly with us in the evenings at the southeast treatment plant for two or three hours. we went on technical tours. they worked on behalf of the community in their neighborhood to try to further the implementation of the project. the objective of the task force was to provide a fair and open review process to continue to develop the process. it was to solicit local community thinking, sentiments, and concerns.

they brought the facilities from 17 down to two. they identified the key issues for evaluation. those were cost, schedule, visual, architectural, and community benefits for the future. the group culminated their work on the digester task force report. you each have one of those in your pocket. it is a heavy document. it includes all of the agendas. the agendas and topics were set by the committee members. some of the meetings were battering for staff. when something was not clear or understood, the task force was very clear and good communicators to us. a lot of time was spent responding to the questions trying to sort out the details. all of the topics are included here. in summary of all the findings

is included. anything in here was agreed upon with consensus. there is a lot of information in here. all of the meeting minutes, agendas, a lot of dialogue that went back and forth when we were getting final comments on the document. this will be with the project as we get it started. this will be what we hand our design team to be able to get them clear on what criteria in the neighborhood is expecting. the 17 different locations were scattered throughout the city. a discussion was held on land use, geography, location, challenges, logistics, size. we talked about all of those things for over a year-and-a- half. we ended up with two preferred locations.

the one on the left in the orange is adjacent to two central shops. this is the railroad tracks. they're both bordered by the railroad tracks. down south is the location where the digesters are currently. we also looked at an off site location on 294. it is in the port of san francisco control. that is trust property. it has trust requirements on it. we had a total of 15.7 acres in the orange. we had about 15 to 20 acres in the blue. we took a look at what it would mean if we were building at south side, staying in the same location. it would be a staggered build where you would have to demolish and complete construction. you still have the digesters

reasonably close to the neighborhood. we looked at the second option where we would be using the central shop site for the digesters. that would have been much further away and adjacent to the train tracks. slightly more on the dollar slide and longer on the completion side. it will require some relocation of the central shop existing use. the final option was more and longer on completion because of the legislative work required to move the trust of the port property so it could be used for a non maritime function. the completion date of the time of the issuance of the report was 2024 south side two additional years at the shop and additional years for. 94.

to look at the three parcels of land, we ended up with two combinations with the digesters at central shop. we had another alternative with the digesters that the south side, se -- at the south side, se. the preferred option would be to have the digesters located along the train tracks at a distance from the residence. even if we were able to have been located here and going slightly north from there, but to be able to keep them as far away from residents as possible. right now, the residents are right across the street. . 94 is isolated from residential. it is adjacent to the old pg&e facility. it is one solid block of land. the challenge is that you have solace and
