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 going to affect . Absolutely. It is mostly people with large amounts of what we call impervious surface which is asphalt and roofs. The school district, because i mentioned a lot of schools within San Francisco are essentially parking lots on they own a lot of land. That is one of the ones we are concerned about. Some of the others we have seen and other cities that have had an impact, churches we focus on, because they do often have large parking lots. We want to reach out to the faith based community. It is large and physical land owners are the biggest. We are developing a full list of who all of those people are. So we can make sure we reach them all. The other thing we want to make sure, like i mentioned we use this as an opportunity to connect with all of our ratepayers to let them know about our combined sewer system. It is a huge benefit we have here in San Francisco, for Public Health and the environment, that we do capture and treat stormwater runoff. Having a line item on the bill that informs our customers about that and also connects them to what the cost of that performance that they are getting we think is a great opportunity. We want to think a lot about how we can connect with Community Groups and use this as a way to inform them about our great wo work. What is spur and what is. The public is looking at this and it says leverage existing storm wattage management. Who are these people . Thank you. We should be better about acronyms. Spur is in urban Planning Group who is a big supporter of Green Infrastructure and other environmentally friendly advocacy around the city. They have been advocating for us having a Stormwater Management charge and for almost decade now. They have a paper they publish quite a while back and they have been a big proponent of this. So i know they would be interested. The Citizens Advisory Committee is a body that sfpuc runs. There is various members some of whom are environmental activists. Quite a few years back, we presented to them on a tentative idea about doing the stormwater charge. They said they would like you to go forward. We want to go back to the people who have said they want us to do this and get their feedback, because we know they are very interested. That certainly does not mean that you are not going to reach out to neighborhood groups . That is why this concerns me. That we kind of point to these people, the rest of the people may not have even known about it or even had a chance. May be they would have been supported if they had known. It may be a little bit much to put out people, you know, like that without people knowing who and what these people are. Because, you know, maybe they are saying okay, they wanted it, let them pay for it. It could be that. Its a consideration. I think, you know, based on earlier conversations we were talking about focus groups and trying to get, you know maybe we should say that instead of ore, include. That is great feedback. Something i am very proud of with all of our rate studies is when we do roll out our rates packages we do a really large amount of outreach to Community Organizations and nonprofits Business Associations and offer any one of the city who will listen to us talk about rates, we will come talk to them. We are working with our Communications Team right now to think about how early can we Start Talking to people about the specific issue and what is appropriate. Very open to your input on that. You will next hear about the contract award for the stormwater database we are hoping to release that request for proposal this fall. We are going to be, as part of the Budget Proposal adding some positions to administer these credit and Grant Programs going forward. And then our rate study which is per the charter requirements conducted by an independent consultant rolling out rates in 2022. The adoption of those rates will happen in spring of 2022. It will be before the commission during that entire rate study. Having a periodic updates on this and other rate topics. So we already pay stormwater but it is integrated in another charge . Right. In your wastewater charge that you pay right now, your Sewer Service charge retake the meter water usage multiply that for by a flow factor and that is the volume of waste water that you billed for. What that covers is all of our operating expenses including for the stormwater runoff. It is already there . Yes. However, we are going to be paying more for this stormwater once you take it out of where it has been hidden all this time . So, individual ratepayers may pay more. You might, my favorite example is a Big Box Store it has one toilet, but a huge parking lot. Right now, its a waste water bill is very low because it has no water usage. However, it does generate a whole lot of stormwater runoff so it is costing the p. U. C. A fairly significant amount paid for customers like that their bill may two other customers, we think for the average customer in San Francisco, the change is not going to make a big difference. For the p. U. C. Overall, we are not collecting more money. We are just trying to reallocate the way we collect our money to make sure it is more fair. 1020 thank you. Thank you. Thank you very much. I do know spur, who we were talking about did a report, it has been some years now, i dont know if its been updated. Maybe that is something for our Commission Secretary that could be distributed to the commissioners for some background reading. It is a complex issue and i feel like they did a pretty good job. At least in summarizing a complaint explain them. This is going and we need as much Background Information as we can get. It would be helpful. Just to let you know, when we did the last rates we made a decision to customers who do not receive water bills to give them a stormwater bill. Weve been somewhat successful. That was the first phase we figure it will take time to get there. We will make sure we redistribute this spur paper. Then we will work with all of the groups i may become back and do another presentation on how we plan to roll it out from just a communication standpoint. Thank you. I also want to say. If we can send that out, that is good. I want to come as a former member of spur, even though it is a premier think tank in San Francisco when it comes to urban policy around transportation, energy and what have you. It is also, i want to make sure everybody knows, it is also that takes the positions on policy. It isnt like a standalone ivory tower intelligent group. It also date it does policy position. When we digest the good stuff that they are giving us, that we keep that in perspective, too. Thank you very much. Also, the current magazine, that is really a great source of magazine. People do read it. They dont always read it when they get it, but at coffee or something they read it. That is something for us to start looking at as well as anybody elses paper that you guys do a very good job of doing that. Maybe that is something we can Start Talking about in some way. Great. Any Public Comment on this item. The next item is water Planning System update. Steve ritchie. Good afternoon, commissioners. Steve ritchie assistant general manager for water. I would like to provide an update on the water supply Planning Efforts we are engaged in with the commission added to the Capital Budget this year, 20 million to get moving on water supply planning for various purposes. Im going to cover today, our level of service as they were adopted in 2,008 that were operated under. We talked about water supply playing priorities and specific goals for the water supply planning effort. About specific projects that we are going to be working on. On the planning structure. There is also a memo with information sheets on the individual projects included in that as well. First, the level of Service Goals and objectives. The first is for water supply which is to meet customer water needs in non drought and drought periods. Water demand was 265 million gallons per day for retail and wholesale customers during non drought years. Dry year delivery needs while limiting rationing to a maximum 20 systemwide reduction during extended droughts. Diversifying our supply, during both periods and improving the use of water sources and drought management. Protecting watershed ecosystems a meeting the anticipated meeting requirements for fish and wildlife habitat. These are the Guiding Principles that the Commission Adopted back in 2,008. Those include meeting existing obligations to existing permanent customers and meeting instream flow requirements. One and two. Those are our true obligations. [reading notes] existing obligations to existing customers, 184 million gallons per day is our water supply assurance to wholesale customers. It is contained in the water supply agreement but it is also very clear the obligation exists regardless of whether it is in the contract with our customers. The rest of the 265 supply to retail customers in San Francisco. We need to bridge some gaps there. Some of the project may not deliver the full water supply that we anticipated. We need to make sure second, permanent and regulatory requirements to maintain healthy habitat. It could be a very large number of 293 million gallons per day to maintain our level of Service Goals while meeting the bay delta plan requirements. That may decrease based on the outcome of state negotiations or litigation. San mateo creek we are contributing about 3. 5 mgd. Alameda creek we have been streamflow which we are currently meeting and we will be bringing to the Alameda Creek recapture project where we are working to recapture some of that supply without disrupting the instream flow. The next water supply planning goals are addressing additional customer demands through 2040. The first is the request of san jose and santa clara to become permanent customers. We were trying to resolve by the end of 2018 we have now deferred to the water supply amendments up to 2028. That is a historic allocation level of 4. 5 mgd each for san jose and santa clara. Meeting increased demands protected by individual wholesale customers. San francisco, under the most recent urban Water Management plan we are looking at an increase of 1 million gallons per day, that will be refined in the upcoming urban Water Management plan. We are to anticipating hearing from the Planning Department are additional growth projections for San Francisco in terms of population and jobs. San jose is looking for an additional 4. 5 mgd above the interruptible guarantee he guarantee. Brisbane has a development which they are looking for 2 million gallons per day. East palo alto had a prior request of 1. 5 million gallons per day and that was resolved by transferring supply guarantees from palo alto. That only goes through about 2035 through that point in time. Those are with projections they look like they need additional supply at that time. What is mgd . Million gallons per day. Again, that covers the goals we are aiming for. And some are very and some are still to be resolved. We cant let time go by without Getting Started on the process. That is what we are looking at potential water supply projects. Can you go back a slide . Share. So, san jose and santa clara are not permanent customers. What i am seeing here is it would not only be historic allocation level, but it could potentially be at this increased level that they are requesting . Yeah, it actually differentiates those, the commitment level for us to reevaluate and make the hard decision on making them permanent at the 4. 5 mgd level. Since that time, since that was discussed back in 2,008 and 2,009, water supply agreement they have developed additional desires. 2008 and 2009, water supply agreement they have developed additional desires. The question of permanency at 4. 5 mgd level, we actually have to come up with an answer on that. We dont have an obligation to increase demands that are without their info form. We want to make sure the commission is aware that they are there i will be asked to confront that decision. We dont have an obligation on number three either, but we have to respond to them . Yeah, the obligation is to give them a definitive answer on that. Great. Thank you. When we look at number four, the goal for making increased demands projected, or even number three, when we look at that are we taking into consideration trying low flow toilets and all of the other things we are trying to do are we looking at that within . Is there a menu of things that they would have to do in order for us to give them this allocation . Everybody, you know, in our service area is doing a quite a good job on conservation. I think nicole can speak directly to that. For example, in San Francisco, we are down to about 42 gallons per person per day. Residential usage. That is based on heavy penetration of the marketplace for low flow factors fixtures throughout. Our wholesale customers as well come are doing a very good job. In the last ten years the bulk of them have been in the 85 gallon per day category. They are now down to about 65. They have made significant reductions. Similar types of programs and their areas which also includes much more suburban landscapes. Their big landscape modification programs that are underway throughout our service area. We are not in the position to tell them what to do, but we are in a position to work with them, and help support them in those efforts. Even if they wanted to become permanent customers we couldnt say, you know, working on getting you down to what San Francisco does, or at least close to it . Is there a goal for them . There is not a goal for them. I think that gets into an area where there may be some, you know, as discussion we have to have about what we can or cannot do. In terms of how they use the supply and their area. The fact that that san jose and santa clara are not permanent means they are not part of the 184 billion gallons per day supply assurance. We are obligated to provide. This is over and above. Exactly how we do that, we do have a little bit more flexibility. Thank you. I have a question on the sustainability goal. Maybe it is just semantics. As it is framed to meet our in stream requirements. It makes it seem like our sustainability goals are lobar rather than being Good Environmental stewards. I just want to quote go on record saying that. Meeting in stream requirements goal seems lobar to me. I talked to the commission in 2017 and we have been working with the City Attorney on how to move forward with those. Im hoping, this fall, potentially through the budget process of bringing you an updated set of Service Goals and objectives covering all things and beefing up the environmental part is part of that. This was done in 2,008. You are right, it is a minimum bar. I hope that is one of our goals. It is a lobar. We do have more to offer their that we can talk about when we bring the item back. Thank you. Lets look at the potential projects. I have broken them into regional and local projects. These are projects that are in the Tuolumne River area. Recycled water and purified water projects. When i say purified water, i mean, we are taking water to a whole new level and supply. Other projects, which helped make the other ones work better and i will talk about them in a little bit. But first, i want to include Regional Water supply projects be considered but did not include, they have been suggested to us before that we should somehow connect to the california aqueduct and become part of the state water project. I think we have no interest in doing that as part of a delta supply. Also, much as it might seem as a good idea to some people, i think that was a very difficult idea. I am not going to say never, because i have learned over time some things, you know, that you never expect to happen, do. I dont think that will happen anytime soon. Also, there is talk of a spillway raised there and we have not included this here. If they can convince us that is a good idea that we may want to frame the project in as well. There are some that we are not including, at this time, because we dont think they are right. The potential Tuolumne River projects. It is part of our proposed voluntary agreement. We have said that we will do Feasibility Study of that. This is actually a landmark thing that the irrigation district had never wanted to talk about that before. They have finally put that on the table. This would entail basically putting excess water where there are big flows in the Tuolumne River into the groundwater basin. So it is a healthy basin that the districts can then shift to in dry years. Leaving us with some of that flow on the Tuolumne River. There would also be an area dedicated to the Tuolumne River. It would be a package deal. One of the districts have never wanted to talk to us about. They are finally doing that. Interbasin collaborations between these rivers, particularly the stanislaus. The plumbing is close to each other. There might be ways we can operate the two rivers in conjunction to actually benefit, you know, the overall environment and users on both rivers on my thinking in terms of a Bigger Picture of water tools to manage. Lastly, dry year transfers. We continue to know that we are going to need to find some way to work a deal with the irrigation district for dry year water someday. Why do you think they havent wanted to talk about the groundwater baking. They see that as their resource, and they see us, i will repeat an anecdote that i heard when they talked about working with San Francisco before. One farmer reportedly got up and said, i dont want to transfer any water to those hippies in San Francisco. He was followed by another farmer that said ive got bad news for you, all of my relatives in texas think everybody in california is a hippie. It is just your perspective. They are very jealous of that. We work well together because of our water rights. But, you know, they are an Agricultural Community and they like to take care of agricultural folks first before they think about shipping water to other cities. That is kind of their deal. We did have a couple of Board Members on the tour of the system on the conversations were very good. Potential regional recycle projects. These are with daly city, alameda water project, Crystal Spring purified water in the Bigger Picture. On daly city, whips, too fast there. The picture on the left is plumbing with purple lines taking recycled water from expanded Wastewater Treatment plant and delivering water to the green areas which are irrigated areas in daly city and then the gold colored areas are the cemeteries and they primarily rely on groundwater at this point. The goal of this project would be to get them on recycled waters so than the groundwater basin can be used much more fully for the benefit of our system as part of the Regional Water system. We actually have money in the budget for this. This is a project that is actually moving forward. The next thing we need to do is work in agreement with daly city, our self and California Water Service Company who delivers water on a roles responsibilities going forward. The next is a map of the freemark yuba city area. It is the portable service boundary, the red boundary there in the upper lefthand corner. It is the el dorado Wastewater Treatment plant. That is where the sanitary district treats wastewater. To a higher level and then transport it to the quarry lakes which are right in the middle and into the groundwater. Then that water can be extracted into the facility which is blackish groundWater Treatment plant. So, they run that from time to time. This would be a steady supply that will travel through the groundwater basin, to be treated there and our transmission lines go right through there. That water can be used directly by our Water District or it could be put into our Regional Water system and utilized that way. That is still to be determined. 23 Commission Meetings ago you approve the next phase of study. The next one is Crystal Springs purified water. This is work we are doing with Silicon Valley clean water. It is a nice fancy name. Potentially the city of san mateo as well. It shows sites where advanced Water Purification facility might be built. And then a potential Pipeline Route that would take water and could send it up to Crystal Springs reservoir. Where it would be blended with supply there. And then that water, as already established would be treated at the tracy Water Treatment plant. Both this and the previous project are purified water projects where we are basically treating wastewater into making water ultimately. Just like nature does. And then i dont have a map here for it. The other is looking at evaluating opportunities for all of the Wastewater Treatment plants in the service area. We know from other situations, it is a delicate relationship that you develop with the Wastewater Agency on that. On whos water it is and how it works. We are not presuming to tell them what to do there. We are just making sure we have identified opportunities. The next potential regional project is the reservoir expansion. Conveyance alternatives and the reservoir expansion. They have been proposing to expand that reservoir. They voted preliminary proposition one funding. They also have federal funding. They are looking at a large number of potential partners without project. This can work a lot of different ways to move water into it. It basically is just a storage volume. What kind of water you move in, when, where, and how . And then how you move water out to particular customers . We are trying to figure out if there are benefits without project. When we expand reservoirs that means we are Holding Water . Yes. That means that water is not going back into the aquifers, back into the ground, back into the sky and involved in what water does. Right. Are we doing anything to make up for that . The waters not going back into the ocean. How is that working . In this case you take water out of the system to move it into it. It does not have a big watersh watershed. It doesnt deflect local water drainage there. Is taking water of the system. Particularly in big years, they are built to take water as fresh as possible to improve the water in the contra costa Water District. It is the only time it would take water into it. This would look at different ways to put water in there. Again, from different mechanisms, all of these intakes work together. The one opportunity that we see looking at here is taking some a nation water from the delta potentially storing that. Are we looking at the ramifications of not putting water back into the underground system . Are we looking at that . Yes. This water doesnt work with the groundwater basin there. It all flows out and that is when you get into the whole bay delta discussion, how much water do you need to flow out to her how much do you divert for different uses. One of the uses here would be the Water District which would be using the water for wetland habitat. That they had developed in the central valley. There are different ways to use it, that is what the state money would pay for would be for that beneficial use that the public overall benefits from. Are we looking at the more reservoirs we build, are we looking at building more habitats in order to deal with that . I mean, the only way water works is when it does the cycle. It goes up and he comes back down. If it doesnt go up in the rate that it used to go up, what is going to happen ultimately . Every time you do a project like any of these you have to go through extensive Environmental Review process to identify the impacts that either will, or may occur and make sure that you mitigate for those in away that goes over and above just taking care of the problem. Making sure you actually make things better. That is the way we do business. Okay. I appreciate that. Thank you. If you look at the calaveras project, might be useful to take a look at some of the mitigation measures that were associated with that. Those are exactly the issues. We do acquisition of watershed land. We do a lot of watershed land protection. That would be perhaps a good case study to take a look at. What you are saying, when we do a project there is a mitigation that goes along with that . Always. That is good. Our case, these dams were built so long ago there were no environmental laws. We have been welcomed into the 21st century by others that we are doing our fair share now. What about going back into the ocean . I think colorado doesnt go back into the ocean anymore at all. The colorado river. They basically dried up that system. Theyre slowly and making improvements. The system is totally oversubscribed. We are not doing that and we are careful that no, we are not doing that. Dont laugh. Ive seen the colorado enough times that is a sad situation. Thank you. Back to the slides again. The bay area do, we have been studying this for some time with other partners, trying to figure out if there is a good place from an Energy Perspective so its less energy intensive. That is what we are doing, looking out the western end of the delta for that. That water could potentially be stored in the carroll reservoir, and would be moving from the system and a way that is protective of fish and wildlife. The big question on that one is how to move water to them in a place where we can actually make use of it which is like conveyance alternatives project in particular there is a redline there, the South Bay Aqueduct which takes water from the delta to the livermore valley. And the capacity of that conveyance system is in some question. If it cannot convey the water from the expanded it is not of any value to us. That is why we are intent on looking at that, but also in the hayward area looking at potential connection to our system. Those are both alternatives we will be looking at. And then the Calaveras Reservoir expansion, we could just about triple the size of that reservoir. In doing so that would give us an opportunity to store water from those large amounts of water that flow in really, really big years. We have talked about 2017 when San Francisco had 3 million acrefeet of water available but didnt have any place to put any piece of it. So that was actually, it would not even have helped to alleviate funding on top of everything else. We would have to be looking at conveyance of water periodically from the tuolumne system on the Calaveras Reservoir to make up for the supply. Is there any other way of doing things other than the reservoir . Are people looking at alternatives . Yeah
