Madam clerk call item 3 ambassador on the short term and long term strategies for the heavy storms that effects cities in district 7, 8, 9 and 11. Hello mr. Kelly thank you. Can i make opening statements. Yes. Oh, im sorry yes, please supervisor yee has joined us supervisor yee. Okay colleagues todays hearing is on an issue that effects most of districts of the supervisors that are here today the issue of flooding this year we have experienced heavy rains this has impacted many of the residents in district 7, 8, 9 and 11 and in the neighborhoods district the upper great highway pine Lake Neighborhood and in district 7 the 15 avenue area and Ingleside Terrace neighborhood and just neighborhood in sunny side neighborhood across over to district 8 and 11 the terrace cayuga in district 9 and the folsom area much of the flooding is exasperated by the geography of the neighborhoods ive heard from my residents it dealt with flooding in their homes and felt their frustration because as a Property Owner nothing more frustrating that is that is actually in a low lying flood area we want to thank my colleagues many who are sitting on that committee and joined the hearing today core cosponsor sponsoring that supervisor tang and supervisor fewer and supervisor safai and supervisor ronen i also want to thank the many residents from those effected neighborhoods that have contracted our offices over the years as well as those that are here today and taking time out of your day or work to come today to see how flooding has affected their homes i believe as a city and county our members with can implement short term and long term plans to maintain the flooding in the impacted neighborhoods citywide ive been meeting with the Business School and Public Utilities commission for several months to discuss the short term and long term plans for flooding mitigation and sewer improvements and want to thank the general manager harlan kelly and the project manager stephanie to present those plans id like to have general manager harlan kelly present. Good morning, supervisors just want to take the opportunity to talk about the flooding today as youll see this is a complex topic with a long history were going to provide you with information you requested today with long term and short term strategies that addresses flooding but first id like to set the stage by telling you we understand flooding is a tremendous burden for those residents and businesses that are impacted in the pockets of city where needing occurs it is disruptive to lives and livelihood and we really want help we have looked at every everything we can do from an engineering stand point to minimize flooding i want you to understand with the significant ratepayer dollars invest we plan to make there will always be a storm larger in the same neighborhood that will continue to flood and if we get a bigger storm than our types can say handle we want to make sure our residents and businesses are aware of their flood risks and have the resources at the disposal to take objections e actions to protect their property were developing a suit of options for Property Owners to make the easiest possible to protect their investment this partnering between city and the Property Owners will help everyone to be more prepared for what Mother Nature brings our way i want to pass it over to Stephanie Harrison with the San Francisco Public Utilities Commission Project manager to present on the progress we made to combat flooding in San Francisco stephanie. Good morning, supervisors and my name is Stephanie Harrison im a project manager for the San Francisco Public Utilities commission can we get the slide on the screen youve asked for a long term and Short Term Solutions so thats exactly what well cover. Excuse me do you have an extra copy. Can i have one, too . Thank you. Okay so in San Francisco a combined collection with surveillance and flows about the same pipes and conveyed to the treatment flagrant before the epa run off or stormwater the largest former of pollution in the United States when our 12r789 hit the ground running it is loiter and nothing youve seeing on Market Street comes into the inclined system we treat over 95 percent of the water that hit the ground running in San Francisco our pipes are predominantly for stormwater in dry weather their by and when enough rain to fill the piecemeal it is 99 percent stormwater more than 99 percent stormwater mixed with sanctuary sewage that is in the system and the system is full and but with the large capacity in the pipes when the system fills in an intense rain the water cant get if it goes to the lowest lying area needing is 16 minutes a large storm up to an, however, and back into the system when the pathway is available the pipes by out. Ill speak from this mike so stormwater is rain that runs overland and sanctuary sewage is it homes and businesses that is in our pipes during dry weather and combined flow the sewage mixes with the pipes our pipes are sized to manage stormwater so graphic you see this is in the folsom neighborhood the pipes their 96 inch pipes large on the streets and in dry weather 6 hundred and thirty gallons her pin a lot of sanctuary flow but when the pipe is full in assigned storm the system is full the water is a exiting the system out of man holes and pipes there is one and 60 thousand gallons per minute running underneath the neighborhood a value of 2 that the plus percent is from sanctuary flow so just to give a perspective the construction in the 1840s a long time and for the First One Hundred years the system was built without strong guidance were aware of by 1941 the 5 year storm was defined by 1952 there was a requirement in place for new developments to be able to contain the 5 year design storm in the pipes that requirement has retained since can you explain that measure of 5 year storm. Yes. Thats a great question so we have over one hundred years of historical dictated of rainfall in the city that data under goes an analysts to look at the probability of different size storms concurring so really i should be calling this one. 3 inches of rainfall in 3 hours that is what the density and the duration of a large designed storm but so in a long term average over over the course of one hundred plus years it will come on a long term average once every 5 years but didnt come once in 5 years if we have one storm it means on my given year that size will occur so when we talk about youll hear about a 5 year storm this is a our design ill be talking about a one hundred year storm comes one time every one hundred years rolling the dice that is in place over one and 10 years in the first part of record we didnt see flashy storms a really dense storm and the second half of the record we see more like on an average basis 9 of them in a 50year period roughly every 5 years but in the recent years seen more flashy rainfall in a 5 or 15 minute period that yes, maam lasts a one hundred year even though that is i use the terminology loosely from our design that is a 1. 3 inches of rain for the design is our model of progression of rainfall that trails off to represent a natural event. I have one question about when you use the term flooding i want to know the threshold that constitutes the flooding is it quarter of an inch how when do you you designated as flooding. Thats a great question. When we talk about youll see some slides on that talks about just water on the streets and hear me refer to the flood risk and flood risk we clarify as low, memory and high flood risk and varies your flood risk depends on the land use the building types as far as what Property Damage so if you have a High Density Residential with a foot of water that is a highrisk but a parking lot that is like a memoranda to although there are different told her that depends on the land use when i say flooding im talking about eninundation and flows on the streets water not getting into the system but flood risk im talking about were talking about usually high and high flood risk yeah. I think it is important you explained the 5 year storm thats fine over 3 time period of one point whatever inch of rainy think that is important to explain not public that you could have a 5 year risk or a flood situation within 15 minutes so when that happens quam at a rate of constant rain divided into 3 hours or almost like having if you were to use that number the ever 15 minutes the rain that came down if you extend to 3 hours during the 15 minutes could be like 10 inches of rain what do you mean. I dont have that calculation off the top of my head the rainfall has a curve associated that represents an storm so it starts off and then the rain peaks and then aside that has the 10 has that shape and one hundred years has a peak 5 minute density or peak 15 minutes density that is 10sh9d with one hundred storm so we could get a storm a one hundred storm in a 15 minute duration that is rains cats and dogs and coordinates to the 15 minute most dense period in a one hundred year storm that is a one hundred year storm even over a 10 minute duration that peaks suddenly and stops and over the duration was not as much rain does that answer your question . I want to make sure we are clear not only about the 3 hours because that is what happened in the flooding it was a short duration where the rain poured and overtook our system. Right when we dine is the pipes we have a dynamic model that looks at the storm for a 3 hour storm including the 3 hour peak if we get the one hundred storm peak flows even if for a short duration our pipes cant accommodate all of that water. Okay. So most recently in the recent last decade or so sfpuc has initiated our Sewer Improvement Program as part of the progress we looked at what well be providing at the level of service from a historically and moving forward and the 5 year storm is endorsed if 2012 and 2016 and most recently conduct a resince study to evaluate the flood protection policy and each representation represents up to providing protection to a one hundred year storm to protection in a 5 year storm we did a benefit cost analysis that showed the 5 year storm is the appropriate service for the San Francisco Public Utilities commission that is consistent with other services do nationwide seattle and new york and chicago have a 5 year storm as the level of protection in urban areas i want to pause here though and say for those who experienced flooding we recognize a Significant Impact on lives and stressful i we have to balance that with the fact that flood risk impacts less than one percent of San Francisco. Do you have a question. Yeah. If you could walk me through the cost analysis ive seen the numbers and what those numbers mean i think that is important to be clear that so am i seeing 14 billion. Thats a great question. Im surprised you can see the numbers. And individual clarity who pays for that that would be helpful for the different numbers and put them in perspective in terms of what where the money comes from. This graph that is shown in the bottom right of the slide not intended not going to walk you through the whole fink or thing by the way, can the bottom line is that to get the city up to our 5 year storm level of protection were already looking spending 2. 3 billion to get the city fully you will up to that point if we want a higher level of protection to the one hundred year storm will cost 16 billion and all of those dollars theyre not tax dollars they are ratepayer dollars customers residents and businesses paying their sewer bill so any cost that were paying to improve flood protection in the pockets of San Francisco will hit all the rate payers uniformly to do our Infrastructure Project if ive mischaracterized that im not on the finance side so the cost to remedy flooding in large storms are tremendous like 2 billion to get to our 5 year storm and every dollar we spend comes from the homes and businesses paying their sewer bills we have to prioritize carefully we need to balance and strike a balance between building flood protection to benefit the pockets of the city that are flooding with ratepayer affordability citywide we have to do this in the face of other priorities as an organization for the wastewater system as well so the 5 year storm level of Service Strikes this balance thats what the Flood Resilience study concluded so supervisor sheehy be i believe to walk you through the slide at the end or substantially if you want to understand the study better. Sorry one more question i know we asked you to keep this to 15 minutes we understand the questions will make the presentation longer than so lets say we decided the right balance to strike was for a 10 year as opposed to to a 5 year and the rate payers so pay the extra money lets pause in the last tomorrow storm that happened where i immediately went to folsom the heart of my district to see the damage and what happened there is what you described earlier that the rain come forward quickly and zen for a short period of time and the flooding happened had we had pipes that could accommodate 10 year storms would that have prevented the flooding in folsom. Not in large storms. So thats frustrating because even if we made the investment for a 10 year or 25 jr. Or one hundred year storm when we have the dense persdz of rain like lastly that might be solve the problem; is that correct . Yes. Yes. General manager piloted if we paid to renovate, upgrade our system to one year storm with the 15 billion have more flood protection for you know large stormsz but in 2004 a 200 year storm so you know theres always going to be a bigger storms like bequeath design the engineers have a standard their assigned and the policy decision for a standard and thats what the engineer carried forward the size of differentiate and the duration of shaking thats what you build but a risk a bigger quarter the storms were facing storms every year but not an earthquake we need to engineer something to have a standard of engineering. Go ahead supervisor safai has a question. Thanks ill wait but on this particular point so you said only one percent of the city experiences severe flooding. Right flood risk in this is built only what supervisor ronen said if this is the case im sure part the city maybe im wrong but a higher threshold than a one hundred year storm. Certainly you parts of the city they can handle bigger. My question will be i dont think the right way to look at it is we have to increase the citys a capacity to one hundred year storm but focus on that one percent for severe flooding i understand you wont get to a capacity of a one hundred storm i was on the ground but a way to look at we zero on the areas that have the one percent of severe flooding and what is the right threshold in Mission Terrace and cayuga well get the city to 5 years that make sense with no severe flooding we we experience it in the last years and the Global Warming is real but increasing at a higher rate our residents are impacted consistently the the right way to look at it what the right they told her to get the areas in the city that sxherns the severe flooding to one percent what is that. Thats a great question but the main thing ill put out there what level is appropriate whatever investment we make and storm is large those areas will flood if we go to a 25 year storm and say probably less but the thing you, you need to understand you cant build up one area have to convey light water to a entertainment plan have to tear up the streets to get to the treatment plan and up size the pipes all the way not as easy in that one arbitrary we want to say one of the challenges that were facing when we are looting those neighborhoods where if you want to make a major investment youre talking about during which that ear which will be happy because youre investing but tearing up the rest of the city to get to the Treatment Plant thats the challenge and so or if you want to tunnel youre talking about large dollars value and i think the other challenge were identified 7 billions of infrastructure needs in the sewer side 2. 9 were investing right now, were planning to spend about 2300 million in flooding but have the Treatment Plant were investing in southeast the same thing 85 percent of that flow goes the Treatment Plant so were making that investment so believe me we have Unlimited Money we can solve the problem but folks that have limits funds so the hard part the balance and so thats where we are where is the balance id like to increase the level but as supervisor ronen said if we invest in a 50year storm and it happened like in january 20th it will still flood people will say rain and its flooding i want to i want to put that out there so when we come up with a one solution we understand the level that people should expect that the sewers can stand well willing to work with them they live in the low lying area. It is kind of like you estimate a project and as you get into the project you come back and make the changes that happens all the time; right . Because the changes need adjusting so the infrastructure in 1990 that was whatever and the informing the 5 year and now realize the Global Warming may not work in those areas you made the commitment to zero in what i was saying a way to look at it were talking about down extreme and the 5 year on alamany you were talking about that so the idea youll be digging it up a way to adjust the one percent of the system may not be solve for the one in january in that 10 minute window you got that was a one hundred year storm in the 10 minute storm 4 in the morning is there a way your laid out the 2. 9 billion to adjust to mitigate the flooding in the areas that are having it. So the challenge is that you just cant upgrade the pipe in the middle or upstream because that is that impact the people down stream so realistically you would like to up size your pipe down stream and build it up those pockets are in the middle of the city and so by increasing you have to tear up the street to make things work thats why you come with a policy because when we are replacing pipes down stream or in the middle you have to make a decision and the real decision you should make that were going to tear up the whole stretch to raise the standard it comes with a significant price tag that will not guarantee that that wont you know people will flood with a bigger size storm thats where the challenge lies. So let me can we cut through the presentation i think what is might have discussions already and as mentioned by the presenter the no way youll present 100 percent so were focusing right now and should eventually focus on it more the system itself but i think in the presentation they might be talking about other shortterm not that will minimize and try to minimize the flooding not one strategy and right now, were focusing on the pipes so if we allow them to finish. Sure. Sure i understand i want you to get the presentation but one question not to move this tread sorry this charter that supervisor sheehy was asking about in the corner the cost to replace the entire system have you done the cost analysis to replace i understand not just the pipes are right where the flooding is but up to the line of Treatment Plant. I was going to come back to that to address that question so one of the scenarios not shown in the graph with the hybrid scenario a level of 5 years but then in key corridors of flooding with a step outside the box year flooding we discovered in the process was that the cost to get there looks like almost exactly not exactly but similar to the 10 year level of protection citywide because those corridors that are driving the costs of the citywide policy so we did look at one hybrid scenario 5 years citywide and 10 in the corridors and the costs are almost as the same as the 10 year scenario the corridors are the big corridors in driving the costs 3 housing unit 7 billion the blue bar yeah. Not meant to be read we can provide a draft of this whole study too it is available on our website so yes. Thank you so the next natural question what does the next storm look like if i look at a 5 year designed storm this shows surface indemnification not flood risk eninundation citywide the light blue the historic ohio drawn those are former creeks the way the typography directs the water before a house in San Francisco when it rains the way the rain flows about the creeks and marshes and then even if well developed the city and the creeks are underground in the Collection System the typography residences we in filled the bay area so what you see in a 5 year storm there are some pockets of indemnification and some that are two small to show up once we address those pockets of flooding there will be a a large storm when the storm comes well look at the next slide an extreme example a one hundred year storm a long term that comes once in every 10 years it is like rolling the dice what the map shows a lot of inundation and it closely follows the storm wastewatero so well do a quick dive into neighborhood examples of water shed this is the folsom area the red on the map is 17 and folsom the yellow area the drainage so any drop of water that falls inside the yellow line flows downhill so a large drainage baseline if the panhandle of twin peaks to Caesar Chavez and to mission the blue owls show once the water goes underneath the red dot goes to Mission Creek where the blue dot is the blue all the water that contributes along the way joined with the system all the blue and gold owl shows you all the rainfall that impacts the system that is in the neighborhood. laughter this is why typography is important well look at the top part of slide shows a map and the red line a drop of water on the ground that red line that the path it follows underneath there is a profile so youre looking at and standing underground and the ground you see twin peaks on the left and a steep decline and flats out in the mission and gradually slopes to the bay what the gray underground on the ground is the ground and the gray underneath it the pipes after vertical riser is a manhole and it is not a scaled the same not actually that flow but give us a sense of the relative flow and what you see that bowl shape at the 7th street and folsom the typography is a goal into there is too many water and this is where the waters ends up and not continues to move along the street and almost too much pressure in the system the water is coming quibble down twin peaks to the low lying areas where 0 water can come out of the pipes. The other example of a water shed is cayuga it is a large drainage area it is a former creek and this yellow owls the drainage area that drains right to the foot of cayuga where cayuga meets 280 and it is 28 Hundred Acres of drainage so like folsom the next slide shows a run pipe if you have a drop of water this is the path youll follow and the Ground Surface looks like and the gray is the pipes underneath and the foot of cayuga youll see the 20s berm shots straight up and creates and bowl shape and culdesack of cayuga. Excuse me why is the berm there. To support the 280 highway to the south in a large 25 year storms neighborhoods flooding can be severe in 3 culdesack with pools of waters. Thats down the street from my house i was down there so so the other thing i want to illustrate this is an example of building at the bottom of a bowl if the system is full the water exits at the lowest points that is on the sidewalk or the manhole somewhere but some homes have low fishthsdz so if this set up were showing part of home if this is your home and the system is full the water b will come out in the basement as shown to avoid the basement stack ups the Building Code requires they allow flow in one direction but not flow in the other direction and these back flows in their covered under the Grant Program the Property Owners can install them and get 2k3wrur78d by the puc. This last within the Manhole Covers are falling off. Water can come out of man holes this is street flooding and water can come into the basement thats Basement Flooding two ways the water can get into the buildings. So we try to avoid the basement back up with backflow preventive and adding into the plumbing code and if you dosido a renovation youll be required to install one to get a permit for the renovation and also, we have the grants program that allows the Property Owners to install them regardless of renovation or not and get reimbursement so we try to avoid the basement through the backhoe but can come out into the street this man holes or who they can surcharge so i go through sewer charging in the next so the question is what is sfpuc doing to the long term projects Construction Projects so ill walk you through this is the map the city and those 5 dots are projects that are under Construction Projects in the works or underway generally areas that dont meet the 5 year level of services to bring you them up to the standard and additionally those areas in red asked to report by the supervisors to other neighborhoods well be providing information on those ill walk through this briefly at mangles doing up sizings and street modifications to manage drainage a little bit better and manage flows the construction contract was last month and complete before the next rainy season this next slide to get water that is flo overland to into the system into construction now and expected to be completed before the next rainy season 16th street this one has a bigger price tag a slower process we have to be more thoughtful and be more thoughtful how were doing the projects the other ones were quicker with less dollars amounts that involves new i think lets along the west portal and contains types into and existing reconvene that is currently unused so on the property itself they have a means right now we get stormwater inundation when it neighborhoods and need to grout the water in there we managed the 5 year storm with the ravine to maximize the investments there so we looked at incremental investment with increasing the pipe size of the pipes by one standard size it could be a huge benefit of flood protection up to the 25 year storm to so in the case by case basis we looked at where will say allow hanging fruit to the investment structure so thats what were looking at and with the engineering phase of this what i by saying this were not just sticking to a hardline to a 5 year standard if there is an opportunity for the investment for a return well consider that. Can you explain commissioner what you just said it is contradictory you make the pipes burn or bigger there and continue to make the pipes bigger throughout the city what youre saying i can make the pipes bigger this outlet to dump the water. Correct a storage option were not making the pipers bigger for the championships down to lower reaches but we have we can fill the baseline and take advantage of the fact it is there and unused and not have a further impact down stream thats a good question. Okay. So the next slide is about the intermission a great area a longstanding flooding issue the documents in the photos from the early 19 hundreds technical changes from the top grateful the bowl shapes owe the typography any project is a high cost so with a limited benefits were benefiting the ifrp mission but during which a long linear path in the mission we dont have a nice large unused basin to store our waistwater because of the large price tag up to 2 million we started with the what are the world of technical we narrowed down to 15 alternatives we did a full evaluation and more recently narrowed it to too so looking at two options in the order of one and 50 a Million Dollar to get us to the 5 year storm level of protection so even after the projects will be implemented the area will still flood in large storms so that where we are right now in the alternatives analysis to look at what the option moving forward project options and go into the engineering and design phase and we are curbing funded to the design all the other projects are from the Construction Design at this time partly we dont know what the costs will be selected. So the cayuga and alamany corridor a tough area like folsom we have the difference here is the reminders of the cayuga the levels of service not flood in a 5 year or a 10 year storm so but when it neighborhoods in large storms it is very severe especially right at the culdesack so the caltrain the concept weve evaluated to help that culdesack to regrade the caltrans property for the surface water and the support 2w0z by building a wall for a retension area helps to reduce that flood depth in a very large storm with a culdesack former of cayuga weve been talking to caltrans in may of 2015 last month we received a phone call we submitted documentation earlier this year describing the concept we have been deciding and last month they have reservation about the land and the support of their freeway so were following up with them following up with the current time i dont know how time i dont know how that project will move forward at this time down stream a question what does it mean the flood depth. So right now if you were in that culdesack and a 25 year storm a large stop came through youll be looking at three to four feet of floodwater so what were doing because in a 5 year storm there is no flooding in that area but in a big storm it really its just really different than what we see in the rest of city. I know that i know the area. Well be looking at the project we havent gone through the whole design by the Technical Analysis will reduce that flood depth to closure to one and a half flood were cutting that in half with that said maybe in a storm that was really border line flood with the projects is in place it will not touch the houses in a large storm if it touches the houses that will be a lot show willer. I understand in the culdesack in a storm i will be standing in a one to two feet of water. Yes. Three to four feet of water. A 95 year storm in the cayuga neighborhood i dont know if we have but i can get back to you on the high storm water. So down stream of cayuga after the flows levy cayuga they go go the alamany by the Farmers Market and through the alamany interchange at 101 that and were didnt meet the level of service so a concept right now to provide better Flood Control down stream to get to our level of service by it has incidental benefits upstream and reducing the flood depth in large storms in the cayuga neighborhood. So would that take care of the foot to foot and a half. The same order of performance similar performance. So even if. In both together might give you a greater benefit but as individual projects they give you about the same level of flood protection. But the challenge the reason this project was in the prioritized as a early project because the flooding that occurred is added lower risk and like in lower alamany less homes impacted more of a traffic disruption in the alamany Farmers Market some homes are challenged impacted but this then the challenge is it is streamline hi cost like folsom you endangered the pipes but all the way down to the bay not exasperating the brothers and sisters but that is 350 million in concept level very, very costly we dont have a current implementation schedule for this project. Just one quick second but this meets our stated goals something our intending to do no matter what in our scope of work regardless of the proposal in terms of the costs this down stream gather enlargement. You have to meet a 5 year threshold citywide. Yes. Just to reiterate this is something that will have upstream benefits on cayuga will take away flooding on cayuga not completely but impact that. Reduce it thats what i mean reduce it okay. Okay. Then two other neighborhoods that were asked about do the folks want me to walk you through those neighborhoods in supervisor tangs district im happy to you a do it quickly. A sewer behind the homes that was built in 1928 and reports from supervisor tang there have been reports of water coming out of the sewers it was built in 1928 based on those feedback we got from supervisor tang in february in march we conducted a field survey and now in the process today as we speak in cleaning and inspecting the upstairs to understand what the project is doing the boulevard that was an upcoming caltrans to have bulb outs on the boulevard and concerns from the community about drainage that is problematic so were working with caltrans on this issue and the upper great highway it itself was places in rec and park there section and the public works maintenance that the drainage from that drains to the sand not connected to the combined system a lot of time there is standing water caused by sand drifts on the road that causes this as opposed to 0 other types of flooding with low lying areas in other parts of the city a little bit of a different nature on the highway. Your supposed to be backing up to the one slide in district 4. Is isnt there a potential k5i7 next to the parking lot or whatever. Im sorry the one on down stream. Down stream saw oh, yes. I have. I think on 23rd a parkway. 23rd and thats your question. I guess im wondering have you throughout about the same concept for the other which is there is a potential k5i7. Oh, youre talking about the ravine that exists now. Yeah. There is a parking lot. So this area is downhill from 23rd. As you mentioned that is downhill yeah. Okay. So were offering for short term and long term lets talk about shortterm so we have o and m operations and maintenance for responses to storms sewer inspections and cleaning and k5i7 cleaning and exceed our goal significantly staffing for the Treatment Plant and employment we ramp up when rain is in the forecast we delivered over 12 hundred sandbags and during a rain event a 311311 call this is next slide the programs the to make it as easy for the Property Owners to manage ill not walk you through but Flood Insurance reenforces up to 3000 an example of a type of a project and another inevitable program and paid one and 40,000 in grant and have about 50 thousand in the progress weve been in conversation with the applications and also adapt a drain residents can adopt a drain and pledge of allegiance to rake it and keep the surface clean of debris and provided with instructions and tools and a Small Business relief fund we are partnering with office of economic workforce and development to address the fired but help us to outreach more to flood disasters as well. So are you also cooperating with some of the permit projects going on in the city for instance, school yards the concrete is torn up and plans to turn overseeing into green spaces but the bureaucracy of urban forestry is looking tearing up situations and having people plant is that part of strategy. May be one of the things in those areas that is a catch so for people not understanding if you actually create for ground youll have less water goes into the surrenders to tear out the concrete and make a way to appraise those neighborhoods with a k5catch basin and i can speak to that in a couple of points one a Stormwater Management that any new development on a persist property parcel has a manager water opt out on the private property in the first place and once it gets to the street Green Infrastructure a term were using to describe some of the things youre talking about like per surfaces that allows the water to go into the ground and prior is those projects in flood areas ill as theyre really good a managing stormwater yearround like today light rain and the water it going somewhere in a flood event there 0 is so much water coming that raining so much rain following the green space infrastructure can do some work by the vast majority of water will come in a big storm were working only Green Infrastructure and working on that in those areas. So thats what we have for short term programs right now but lets talk about what we were doing in essence steps on a long term basis for the construction for our Capital Improvement were working on a Collection System plan you know as i mentioned flooding is one of many issues that were faced in San Francisco and long term were currently finishing our priority projects into the bowl one prioritized capital plan that the oar seismically and climatic change and Environmental Stewardship and considering rate impacts one consolidated capital plan and presenting that in july to our commission so thats the long term next step for construction but even if we make the investment there will be a bigger storm so the same neighborhoods will be vulnerable what can we do yonder infrastructure well continue to explore the options above and beyond the infrareds ive talked about the existing programs but heres a glimpse of future programs being evaluated so for these programs we would be looking to identify areas that be vulnerable to flooding we want to people to be aware the flood risk, we would potentially use identified areas to require flood resist construction if youre going to redevelop our property lets redevelop in a way that is better than having building standards and a Building Code that requires certain types of of construction vulnerable in areas of flooding and along the coastal areas we are expanding that concept into the areas in the water shed back flood and then also disclose at the point of fail so people that are buying improvements know what theyre getting and investigating in large grants to flood prove properties or structures and were investing in the concept of select voluntary Property Acquisition so for those programs their preliminary programs the once youve talked about and hope to have a better defined Implementation Plan in coming months so with that, im going to turn it over to our general manager harlan kelly if there is negligent you want to add. The last two options are those place holders can you give us more think an idea of what i mean coming back with something more, more there. So the plan is to weve been having initial conversation about what we can do we recognize whether investments a storm system the larger areas will flood we know that we can only put so much investment so what we really wanted to flush out giving folks options the one we mentioned is raising Peoples Properties can be an option for someone that never wants to into custody you live in the bottom of bowel we can only invest is a certain amount to work with the owner to voluntarily purchase the house other cities have similar programs were contracting them and City Attorneys Office and because we dont have sales tax we have at the sewer system rates so we have to look at what are the pro tem 218 challenges well flush all the stuff out i gave the direction to staff to kind of really develop some options so we can come back to our commission and also the board and mayor to kind of unveil what we can do as an organization to really helps to evaluate folks that live in the outlying areas. When you talk about raising house how i mean. Selfdepends on the type of structure that where we are. You know for me cayuga. So. It is it a commercial or an apartment and you know maybe even raising we have to look at case by case supervisor safai. So i think one of the things that is you know anxiety provoking they know the rainy season were coming to the end of that hopefully. laughter from a waterside or now we have too much water. Hopefully for the folks inform that the police that on a daily basis i know youre investigating overseeing options so is there a timeline you can say it us you might want to come back and present a more concrete program we have the luxury of the rainy season coming to an end but in terms of potentially if 33 they want to sell their home dont believe that 34 people will but ive heard from a lot of my constituents we share this Area Supervisor sheehy and i cuts in the middle he has one part i have the other were there they go so thats one but still that option is one but the other one is raising up 9 foundation i mean in our area all singlefamily homes so youll be talking about raising a foundation three or four feet the timeline im trying to get at. The timeline we hope to come back is around july or august where well have hopefully whatever flush out the options and you know to raise for example, singlefamily homes what the option for them we want to give them options because as weve been saying over and over if you make an investment because you know living in that ear we make a significant investment and as soon as we finish the flooding it looks like were failed we want to be up front were making on investment to minimize. When you talk about acquisitions i hope youll look beyond the value and what was paid for someone to maintain be able to be in the city and theres a delta between what the marketrate felt properties and what it takes for the equivalent in a part of the city that neighborhoods the delta will be challenging but if you know full compensation for the people that will still be in the city still have the amount of space and not flooded you know that might be the difference between people willingness to participate in voluntary acquisitions or not like my house thats something we can definitely look at as you may know prices based on neighborhoods so and this is challenging to buy a home in San Francisco but well definitely look at that as part of our analysis so you know pretty much weve covered all of the challenges that we are facing and i think that the most important thing i want to say that you know we understand that flooding impacts a lot of folks and the challenge of the cost and disruption that will cause but no guarantee they will not flood again, it is a partnership were hoping to work out and we are planning to make a significant investment and over a long term we want to sustain to put money aside and endorsing the areas the city and protect them from flooding with that, we went over the options and here to answer any questions.

Im pat a member the association and want to bring to your attention your concern the historical flooding that occurred from the Manhole Covers in the sewer easement from 2150 overlooking the park repeated seasonal flooding those two the sewer easement behind the homes is possibly one thousand feet long and contains 6 Manhole Covers with the sewer system has been overwhelmed as a result, the manhole controversies have felon off and the water has escaped in an effort to correct those two Manhole Covers were secured and pictures provided for your reference the other two sewer lines theyve been surveyed by camera that area is difficult to assess wed like the entire one thousand surface to be taken care of. This has been complicated by the fact if involves 3 agencies caltrans, San Francisco Municipal Transportation Agency and the department of public works for the last year candidates and dpw have required a wrap around bulb out but the plans by dpw and caltrans dont meet the needs of neighborhoods and a major traffic assess road for Pine Lake Park and adjacent streets wed like introduce is an open hearing and this was done last week and the neighbors have not had a chance to look at them. Thank you. Next speaker, please.

Good morning my name is elaine i live in Mission Terrace thank you for the opportunity to speak i appreciate all the attention and the consideration from you supervisors has taken a lot of time to get transaction with look like of our leaders broov 0 thank you for finally giving us time and attention that is a nightmare we face everyday so id like to show from january 20th what were doing there. Overhead please. inaudible . Can i replay that i dont think that everyone saw that. Can you kill the lights or inaudible . Thank you thank you for your testimony.

Thank you. Overhead please. So im just going to play a video of the flood from january 20th supervisor yee good to see i live in the sunny side neighborhood not a low lying neighborhood from the side of a hill and we have been flooded repeatedly 2014, 2021 twice this year in 2017 were hopefully that the sewer improvements proposed for for better or worseer low fix this a couple of things i want to point out one they talk about 5 year storms and 25 year storms and one hundred year storms twice this year so i kind of want to reiterate when they talk about the storms their happening much more often than 5 and 25 years the other thing i want to mention theyre talking about the rate payers having some burden from repairs to flooded areas i want to point out as a matter of equity that water is coming from those way fastest does seem like this is something that we all have a shared responsibility for and it seems to me that it is appropriate that cost should be distributed across the city since the wait comes from all over the city were all in it together and want to see the city make more of an effort and share the other speakers concerns that their does seem to be well, if
