they become a reality. >> president ann moller caen: any other comments? any other commission business? seeing none. i wanted to stop for a moment and say that ms. hood is going to keep us apprised of the score. >> bottom of the third. 4-0 giants. >> okay. item 7. city clerk: item 7, sea level rise.

>> madam president, emilio cruz. what i would like to present you today a brief presentation on the sea level rise and the program improvement prament. -- program. the multibillion dollar program to create and invest in the city sewer system. we are not only looking at new technology but what's going to influences from the operational system. we are looking at industry trends. we are also looking at

regulatory requirements and what we are projecting for the next few years and based on the facilities that we are designing for the next few years and climate change as sea level rise and how those will impact the structure. the csip has invested in our analysis of the sea level rise. we have a bright scientist by chris may, she has 18 years experience in this industry and not only has a contract the with the city of san francisco but also other cities in the bay that are with the rockefeller foundation that gave the city worldwide grants to analyze the sea level rise throughout the world. the city has put together a task

force to look at this issue obviously from the port of san francisco but also significant impacts you the sf puc because of what runs along the perimeter of the bay and you can see it's chaired by mr. david be har with the puc. he was out sick today. we have the guidance. so the city has taken a look at guidance and the science kind of varies. they have looked at the least scenario and the possible scenario and we have the 2050 as the mid-horizon and 2100 horizon. they have suggested the half of the

scales, but at least we now have general science agreement on what the potential sea level rises are for the bay area looking into future. if you look at our overall process we have taken a look at the science we then assess the vulnerability of the infrastructure that we have. once we understand where it is vulnerable with the sea level rise and we assess that refk to the facility whether it's a port harbor or our overall collection system or talking about private property that is a major impact like at & t ballpark and we plan for adaptation. how do we adapt to the potential sea level rise. there is a study going on now where we take a look at mission creek and how we are involved in that study because the rise at mission creek is

hang the economic impact on the city because of 18 ballpark ucsf and we have the residential house boats on the creek. they are looking at that and taking a look at how we can adapt to this change from an infrastructure perspective and the last steps will be then coming up with a plan, implementing a plan and starting the circle again as we get more information. so, again what we do is we take a look at the assets, we determine the vulnerability and come up with a plan and narrow the funnel as we move forward. not unlike the process as we went through our biosolids. there is a recommends that we look at this mean level rise of 36 inches for 2 100 design. what we are looking is the

status level rise and the 36 -inch rise over the life of the infrastructure. that looks at a status condition not a storm condition. when we have potentially 100 -year storm with that sea level rise and again trying to determine how we adapt to that and at what cost. finally we've developed these maps to show kind of existing condition, static sea level rise condition and storm conditions to see what piece of real estate along san francisco are going to be most impacted should we in fact see king tides and hundred level storm. this is a very preliminary briefing to let you know there is loose

-- a lot of science going into this and the potential impacts and we have not come up with any final determinations but we want you to know that we have the city's guidance by that committee and now we are assessing the risk based on that guidance. we will develop cost and schedule impacts to adaptation and we will take that information and plug it back to the ssip program to let you know if we need to make adjustments to that plan based on these new conditions and based on this new science. that's all i have for you today. >> so this came out of the effort that was really citywide, right, from capital planning? >> yes. >> this is directive for all city agencies and infrastructure to really plan foresee level rise in the coming years?

>> it was led by the city mayor and administration. we have already acknowledge the sea level rise and that was the reason why he was appointed to the chair because of his focus on the water adaptation to the puc itself. this is a citywide effort and we are not looking at only the obvious structures but the seawall itself as the impacts as the sea level rise and the seismic issue because the seawall is coming into place. >> the baseline number for planning? >> that is the guidance that was approved at the committee two 2 weeks ago, i believe it was.

again this is completely as an iterative process, we look at the impact, we look at how to adapt and then at the end of the day it becomes a return on investment question of our public funds. so the options to adapt can be quite varied. for us there may be more limited because of the needs for our facilities to sit where they do sit but pretty amazing consideration have been thought of along mission bay to two of the plans that are being considered. one of them actually looks at what some people refer to as the hong kong approach and actually building up the land and developing upward and creating a larger bedroom -- berm -- another plan is a venice

approach which we are going to be in undaegs in case of a storm and have all the building first floor be water proof and the streets turn into canals until it passes and come back to business as usual. there is no real hard cost analysis. >> is there any information about the flood suspect like the big problem areas, problem with infrastructure? >> nothing as of yet. the biggest challenge that is evident is the fact that we have effectively a primary system through the release during the greater storms where it's designed in such a way when

it fills the solids float to the bottom because of the shape of the box itself and floatables like cups and paper flow to the top and when that box gets filled starts discharging into bay and about 95 percent of the water release is rain water. if we see a 36 -inch level rise we will see a storm where it becomes underwater and it won't release into the bay and b, we'll start to bring into the water and start affecting the biological plants. that's something we see a need for a fix. we don't have a plan, but we know we need to develop one. other areas in all likelihood

need to be protected and on the ocean side the entire study on the impact of the rise and the taking of ocean beach and one of the things that the city is looking at is the potential for letting the road and highway and gray infrastructure. >> one last question. so when storm water comes in, if it ever rains again, when storm water comes in that theoretically contributes to the problem, correct, because of the combined system? >> yes. >> so an integrative approach whether it's quickly or not is the question could really help either adding green or gallery type stuff. >> we are definitely advancing the water shed analysis and all the other urban water sheds taking a

look at the water and potential of multiyear storms. we are looking at central bay side as the a because the current main is not seismic sufficient, but b, as to having the ability to take on more and coupling those analysis with the green infrastructure using infiltration and moving forward on all of our eip projects. i don't remember exactly what number but capturing the millions of gallons of water along sunset over the course of each year. we are looking holistically as to how we are going to manage water in the major event of storms. >> thank you. >> mr. cruz, do you have any timeline for the assess ment of existing assets that we have?

>> yes, we definitely want to complete this assessment of what would be impacted within a matter of months then the next step to determine the level of impact which will also be a matter of months and then start to come up with the adaptation plan. that plan will take longer because of the potential dollar volume that we are talking about. if we have identified plans that would cost a few million dollars to implement and this those to go forward on and there are those that would be hundreds of millions of dollars and in which case we will do a whole holistic analysis and tell you what this is what phase one and phase two look like. >> i would like to add as part of the sewer improvement program we have experienced sea rise as it

relates to water intruding in our systems. before we never encountered that but in the last couple of years we have started to encounter that. so the way is to put back water flow in there, but as the water rises we are going to have to start pumping because -- so we are looking at how we identify triggers where we need to start taking action. that's another part of that. >> overall today our system that is capacity to collect and treat 775 million gallons per day. as part of the overall water shed analysis for bay side and green infrastructure we are looking ways to expand those numbers for when we do have larger storms. >> very good. thank you. >> one last question on that.

the state water bond, it's going to make some funding available. ticket pricing is a little daunting because whatever direction you go, it seems like it's going to be expensive this adaptation whether it's a technology piece or setback piece or even letting third street turn into canals. is there an opportunity to access the state and i know there are federal funds for infrastructure investment and green? >> we are looking into it citywide. part of it as the puc we are looking at our own impact and citywide, the city will be looking at the capital process and what capital has the highest priority for money in that vein. we are also looking at the state revolving funds and because it's a low

cost loan it has potential of millions of dollars and we have access for those teams now to be one of the first agencies to take up the large advantage of the rules around the state revolving fund . >> even when susan allele was general manager, she worked with other utilities to create an organization that really focus on climate change. i'm participating on that and nacua, they are all experiencing climate change. the utility industries we are bonding together. in fact we are learning a lot from new york, from sandy. so we've been talking about how they are dealing with it as it relates to climate for their infrastructure. >> i also want to appreciate your leadership on this because a

lot of people are talking about how san francisco is presenting it's in the leader of climate change as far as utility gov. i would encourage you to stand in that place because it's going to be a real issue in identifying the resources to help us get to the next 100 years is going to be critical. >> mr. david be har has been doing an outstanding job on that working with all the city agencies. >> thank you. >> thank you, i do have some public speakers. >> thank you, and i think this is a critical issue to talk about with sea level rise and i don't think people understand this. we are down to 69 hundred. it's such a broad topic that

people don't understand the impact. what i would like to talk about it that we are happy that emilio is looking at proactive measures. one of the reasons we have sea level rise is the amount of night at -- nitrate that we are putting in the ocean. francisco and i met with the team to talk about denight if fiction and met with other agencies. this is not just san francisco's problem, because everybody is relying on what we are doing here in san francisco and i want to restore our wet land and look at how we can balance some of those things because if we are talking about flooding third street and those communities, we have to look at the best situation. the team is looking at those, but if we can broaden the perspective

of storing our natural protection and looking at reduce what we are doing to contribute to sea level rise, we are talking about the top 5 and of course the east bay and we are talking about hundreds of millions of gallons a day to address the united front and to begin to stop some of the sea level rise from a proactive rather than reactive. we need to keep track of this and stop doing this because a lot of it is man-made. we can continue to reduce it and bring the cost down because it could be very expensive to try to reduce this. there are some things that we have the opportunity to talk about it and work in collaboration. thank you. >> thank you. mr. decosta?

>> first i want to talk about visit courtney. i want to thank you for what you did for the last years. i also want to thank you for being open when i approached you about some matters. i wanted to look at sea level from the point of view of the first people, the marl owney. this is their land. i also want to look at it from the point of history where some three women took upon themselves to stop the infield mostly from the east bay. if we go today to ocean beach, we can see the havoc that erosion is

creating. but if we go to candlestick point to the state park, we can really see the havoc of the erosion. one of the things that we talk about sea level is we are talking generalities. we could not be build this high rise buildings, using clean hetch hetchy water. this commission seriously should warn the developers and san francisco planning to go into gray water, seriously. we can't be taking millions and millions of clean water from hetch hetchy so that these people will live in these condominiums that cost $5 million and $10 million.

that we use the water but waste the water. that no more to a ir, b and b. they are completing without the industry. what our hotel industry can regulate the consumption of water, we could not with such entities, thousands of them. so in the year 2004 it's true that we had a conference and i attended many conferences some here in the bay area and some other places. we addressed the sea level in england and other places and here on the east coast. we would really learn a lesson very soon when we have el nino affect us right here in san francisco. thank you very much.

>> president ann moller caen: thank you very much for the kind words. do we have anymore public comment? is there any additional public comment? seeing none, public comment is closed. >> next the report. >> i will update you on the giants game. 4-2. the update on the drought. steve ritchie. >> steve ritchie for water. i'm an angels fan. the drought update. we'll be brief this time.

things are reset and we are moving forward. here is the slide that i always use about our storage levels which hetch hetchy reservoir is 7.6 percent of maximum storage level and we have about 42 in water bank, about 240 thousand ,000 acre thousand acre ,000 acre feet about 58 percent in storage and we are doing pretty well on storage right now. the precipitation chart is different because we've gotten to the end of the water year. i ended up with a wrong presentation, this is older here. but in effect, the line peekt a little bit at the end in the blue line, oh yeah, the chart in front of you is true. the numbers are slightly different in terms of of storage but pretty close as well.

the precipitation we have a little bit to catch up with 2007 and now we started with the new year with october first 1st and we haven't had precipitation this year so far. that may change this afternoon wechlt started now with the fresh slate and we move from this point. on the snowpack, this slide hasn't changed for quite some time because there is zero snowpack right now and moving forward. the interesting thing that happened two 2 weeks ago is the deliveries picked up a bit. you can see they are still below the dotted black line which is the level we need to get to to achieve our demand production. we are definitely staying on track for that that we kiev production.

and this coming week demands to go down again because the temperature did drop. in terms of total water savings, we are at 7.6 billion gallons. within about 450 million gallons of achieving the reduction we need to achieve for the entire year. i'm quite confident we are going to achieve that. well have achieved the intent desired. we caught that up and together with the campaign that got us there as well as people stepping up and doing the right thing. we have done what we set out to do. and it is a new water yearment that's what we look forward to at this point. what's it going to be, is it medium participation, it's going to be a similar year, if it's a dry year, we'll keep up with the 10 percent reduction, if it's drier,

we'll have to implement a 20 percent demand. in fact we talked about if it goes in that derek, what -- direction, what kind of action, the demand has been on going for the next couple of years. achieving that extra level will take some real hard work on the part of everybody. we want to start planning that in case. we'll be looking over the next few months how precipitation looks and a good or bad year and the precipitation this year will stick definitely going into future. people get the message and stay there. so at this point i'm happy to answer any questions about it.

caen >> if we had to go 20 percent would that be on top of 10 percent? >> no. 20 percent as we talked about already looks like a pretty steep hill to climbed. >> president ann moller caen: okay. >> how that is rainfall been happening over the year. >> each year is different. if you want to look at a colorful chart. you see the precipitation, but it doesn't seem to be moving yet that we can observe. this last year for example was a bit later. it was delayed this year. >> so we can't really with much certainty say that by now or a month from now we should have x

amount of rain. >> yeah. if you look at 2012 and 2013, the first part of the water year from october to december was incredibly wet and then it stopped. so the calendar 2013 was totally dry. but we really had a big early in water year 2013 which happened in november and december of 2012. >> so is there something we can do to capture that rain to be smarter in the event we start seeing these patterns and when it dries up early on at least we've put out our barrels and being able to capture the best we can? >> yes, we are moving forward to revitalize the rain and water enter prize and in terms of our reservoirs we operate them
