And those are the applications . Implications . We can posit any time because we are doing things and phases and this is something we do not have the luxury of not doing. We are, you know, working in increments to figure out how we can reduce each one of the component costs and working with the contractor and bidding it out. We are pretty much, you know, going through the path of bidding out each package and we can let you know what the trends are what we are doing and mitigate it. I mean, at a certain point you have to decide if you want to continue building this or not . Im just speaking for myself. On the commission we are going to likely commit to continue to build it. I want an understanding of what that actually means wheres the money, did it come from some other important project or is that coming from reserves. How does that really look. We are planning to present to you, as soon as the new director comes on board to look at rhe baselining everything based on what we are experiencing now in the marketplace. This is something that we will use to kind figure out out, you know, how expensive things are now. We will look at all of that. A comment to the general manager. Also, that would be part of our planning process. Great. Thank you. Quickly switching gears to our geotechnical aspects. In the last meeting, that the commissioner brought up why we are not going to the bedrock. We have a systematic approach to address geotechnical design. There are five steps which are listed on your slides. The first step is basically to look at existing geotechnical investigation in the region. The second step would be to look at what are the data caps compared to our Site Specific requirement. On the third step we have the Site Specific exploration plan and do the geotech. On the fourth step would be based on the data that we get from actual exploration on the site that the report comes out and guides the Structural Design in step five. I will go over quickly how that all works. What you are seeing is the general region of the southeast plan. You have the 280 freeway, and we are right on the clarifiers and headworks. Yeah, this is our headworks facility. We look at the region what has been done in the past. All of these. Dot you are sitting on the map is the previous investigation in the region. We look at what is available, other data gaps. The next step we prepare a Site Specific exploration plan. We have a seven that we did at the perimeter of the existing facility to identify what layers are where . Wheres the bedrock . What kind of soil we have. Those are the important things to identify early on on the design so it guides the design. In the next step would be the final design based on the actual data of the site. This is an example of an older control area which is the height limit is 64 feet for the facilities. This is probably about 60foot high. You see the design is based on the actual data of the site. That is the reason why we do the Site Specific. Quickly going over the major differences between the skyscraper, vertical load which verses headworks which is on your right site. Typical height of some of the Tall Buildings could be. Our headworks is about 64 feet tall. That is the major difference between the two. On the left there could be 90 100 Story Building. Ours is like fivestory, 64 feet height. On the design approaches, the skyscraper we have two examples of what could be the design on the left. The skyscraper doesnt go to the bedrock, the foundation. What happens those could be 90100 feet deep piles. And there still a stress at the bottom of the foundation. Keep pushing so you can have a possible settlement. There is still residual stress at the bottom of the foundation. On the right side, the skyscraper which is approximately 200300 feet all the way to the backdrop drop. There is no settlement expected because all of the stresses are being taken to the bedrock. These are the two examples of the design of the skyscraper coming back to the headworks. What we have done is on the left, what you see is our Site Specific exploration. Our maximum depth is about 120 feet. What happens is the soil based on the data, if frictions the soil allows the stress to be diminished at around 120 feet. When it goes a little bit beyond where the stresses on the left side, because there is a safety factor that we incur. Were going deeper than what is needed. We dont want to go on the rights over the length of the pier goes all the way to bedrock. Just adding extra land for no good reason. It just increases the cost. Those are the reasons why we do not have to go to bedrock. All of the stresses being taken by the friction of the soil. I hope that answers, you have a concrete mass of a 90 Story Building versus our spread mass. Ultimately we landed on this design. We have 2448inch depth. On the ridge it is about 120 feet long pier system. Toting total number of drill system is 700. Because of the friction, the only kind of system we dont need to go to the bedrock. Just quickly on summary, scope wanted to is about 75 complete. They are trending a bit higher than our estimates as i demonstrated earlier on the slides. Fifty plus packages are still to be advertised with most of the dollar value of the project. The team will be looking into some of the mitigation strategies that i described earlier to slow down, advertising, or break a packages according to the need. We will be looking into last but not least we will continue to enhance environment of Team Collaboration to have a collaboration with the designer, the planning folks and the contractor. We will continue that. With that i would like to see if you have any questions that i can answer. Question about, i mightve asked you this in the field, but i cant remember. We know the climate is changing, and sea level is rising. That means that the creek is going to rise. I guess my question is around the resilience preparedness that you are doing with regards to that. I didnt really hear the pilings, and that design of pilings is also going to be in the event of water seepage, flooding and whatnot . Headworks is designed based on the Sea Level Rise criteria, establish out the city. All of our electrical facilities are above the line of the projected Sea Level Rise. All of our program reits meets the criteria of Sea Level Rise guidelines. That has been in consideration of our design. To keep the elevation higher. I hope that answers your question. It does. Im still nervous. But it answers my question. Thank you so much. Any questions, commissioners . Thank you. Public comment on the item . This was a good presentation on the topic itself. Here is a way of looking at things as human beings having intelligence. You could have used our warehouses and a lot of space that we have in the southeast sector. [inaudible] saving millions of dollars. Rather than putting the burden on the contractors. If you look at how things are going on, you really have to be a real big contractor having a lot of money insurance to bid on a project like this. Even if it is a low bid. If you look at the last two bi bids. The difference is about 1. 5 million. Could we have done that . For sure. Did anybody bring it to the attention of the sfpuc . For sure. Did sfpuc do anything about it . No. We are used to like, okay, that is a low bid at some time. Lets delay something for a couple of years. Of course the price will go up. Why would the price go up . Do you know who is in the white house . Do you know how to spell tariffs . Do you know how the guy works . Screwing things up, our economy, our safety. You do. So what do we do . We ask questions. Questions about what . Do you know this hood winking has been going on for how long . We intended initially, early on, over attended initially, early on, over 30 meetings. The community. Yet people serving some chicken. They eat the chicken and forget to ask the right questions. I am the only one left. All of the sellouts, they just want the money on a platter. Are they serving our community . Is it benefiting our community . Lets look at the digest, the stench in the year 2019, it is thinking. Were said and was stinging years ago stinking. Worse than it was stinking years ago. We have to ask ourselves; do we have the guts to do the right thing and save this city and county of San Francisco that is going to the dogs . Thank you very much. Any other Public Comments on this item . Next item, please. Before i move to the next item, i just want to say that the next Commission Meeting we talked about the Southeast Community projects because we have three projects. One is the biosolids. This project that we talked about, and then 1550 evidence and how we are approaching all of those projects together of making sure that we look at the Environmental Justice portion of it. We also look at how we are engaging the community, and how we are engaging the local businesses. We are trying to coordinate everything. They are all competing for resources in the community. We are going to make a presentation on how we are trying to maximize efficiency of trying to utilize the community in the local businesses there. And then we will come back and talk about the biosolids. The one advantage of the biosolids is we are bidding out some of the early packages. The major ones we are getting prices and we are looking at what the costs are. We are trying to look outweighs, you know, we can minimize the trends we are seeing now. That is something we are moving forward and will present to you what we are seeing as far as trends and stuff. I just wanted to point that out. Have a question. I probably shouldve asked him, but im sure you know. When you talk about a new screening design, you are talking about the design of the plant not necessarily what you are putting into do the screening . Yeah. Plant design . Ya, is that what you are referring to . Am talking about the facility itself. It was on one of the slides and he said there was going to be, the screening design was going to be more efficient. I was wondering if the design of the plant itself or what were we going to use to do the screeni screening . Yeah. The screening efficiencies based on the equipment selected and i believe the equipment so liked it was pilot tested to make sure the approval rates were in line with what we were expecting around 90 . We tested based on the influent that comes into our headworks facilities through Pilot Testing to make sure which perform and we have recommended product that we selected and we are basing our design on. While we were at west tech i think we saw what you had chosen. I just wanted to know, thats going to be really amazing. I also wanted to add a Little Something that would be good to get. You could see what was going on because they had cameras, they had lights. I mean, i dont know how expensive they are. At least if we had one, with the cameras, so we could see what was going on while things were happening. If we only had one, when things do happen if its another one we would kind of nowhere. I just wanted to put in a pitch. Im sorry. I mean, it really made a lot of sense. As we look at money. If you wait later on, then its going to be more expensive. If we were just to get one, that one could tell us what was happening with all of the other ones. Its an idea. Thank you. All right. The next item is the update of the development of the stormwater components of the sewer system chart. Good afternoon, commissioners. My name is aaron franks im the administrator, im here to update you on the development of the stormwater component of the Sewer Service charge. We are going to start off with a little bit of background about how we got here today. Give you a quick update on the current work we are doing and then finish with the next steps that will be coming to you in the future. As you know we have a combined sewer system here in San Francisco that manages sanitary sewage and stormwater runoff. Far quite a few years now, the rates team has been looking at how we can redesign our rates to better reflect our combined sewer system. A rate study in 2018 calculated 27 of our total waste water costs is related to managing stormwater runoff during wet weather events. Right now our existing customers are paying for all of those costs through their sanitary Sewer Service charge. That is currently based on the meter on water usage that comes into your building. What our prior Rate Consultants have recommended, and the rate study was we should actually separate out our Sewer Service charge so we have a stormwater component and a sanitary sewerage component. Utilities are doing across the country. We have been doing some work since sent to figure out how we can implement this change. This is a pretty big rollout. It will require a lot of internal and external work. What we decided on in the package which gives four years of retail rates we will do a phased approach. What we implemented then, and is currently in place, is the Sewer Service charge for unmetered property. The idea is that there are Certain Properties within the city of San Francisco, vacant lots, parking lots, they have stormwater runoff when there is a rainstorm. They are not currently paying for anything because they do not have water service. What we did is we took our existing sewer rates and calculated what the average existing customer is paying right now for stormwater runoff. We decided to charge these unmetered properties for their share of the cost they are imposing on our system. The other big thing we put into place is a Grant Program that is going to provide private customers with money to install Green Infrastructure that they will put on their properties to manage stormwater runoff. This is one of the big lessons learned. This Grant Program really comes into play when the full charges rolled out, because people who have installed infrastructure and Stormwater Management on our reducing their burden on the system will get a credit on their bill and the same way if you conserve water you dont pay as much for your water bill. What we are gearing up now to do that we are planning to roll out in 2022 which is at the beginning of our next big package is the phasein of the stormwater cost allocation. This is something we want to phase in over time although this change does not make the puc. There customers especially ones that own a lot of property in the city whose bills go up. We are planning to phase this and slowly over time. Also planning to roll out the Credit Program that i mentioned. Any customers and the city who have installed Stormwater Management. Whether they received a grant, whether they just really care about infrastructure and did it on they will receive a credit on their bill that recognizes the lower costs that we have incurred to manage the stormwater from their properties. A little bit about what our current work is doing. We are getting ready to issue a request for proposals for a consultant to have a database that will connect to our Customer Service and billing system. What i put here is a screenshot from the city of philadelphia. They have hundreds of these if you just start googling. You can find quite a few. What it does is it lets customers scroll into their particular property and look at what we have measured for impervious services. It is things that cause stormwater runoff. That is what the charge will be based on. This database is going to connect to our Customer Service billing system. Its a pretty big infrastructure and we need to make sure that we get the billing right. That is a very important thing we have to focus on. Its also a great tool to connect with customers. It communicates what their charges based on. Some of the things we are looking at is letting customers make make appeals if they think their information is inaccurate and the system. Or potentially apply for credit right through that. That is something we are excited about rolling out over the next few years. Gis is Geographic Information system. Google maps is gis. It is just the idea of databases that are on a map. You can click on a restaurant, you know pops up with a phone number, the address, the star rating. That is a gis database. This will be the same thing except it will tell you about your stormwater runoff instead of what your star rating is. The other big where we are trying to work on is our outreach. This is a change and we recognize it is not something that most san franciscans think about every day, there sewer systems. We are really doing this in a lot of ways as an opportunity to communicate with our customers about what they are currently paying for with their Sewer Service charge. Right now our Communications Team is working to get some clear messaging on key talking points about here is what you currently pay for. Heres how it is going to impact you. We are also identifying the customers the bill will go up as a result of this change. We are trying to reach out to them right now. We give them warning ahead of time before we roll the charge out in 2022. We also connect them to our Grant Program and encourage them to apply for those grants which if they installed Stormwater Management will reduce the bill on the long run. I know we have had a couple of in the commission from the school district. We are meeting with them and we are excited to work with a lot of our partners both governmental and private to think about how we can help them. Can you give us a couple of examples of highly impacted customers that it is go
