people in waste water enterprise. so it is time for me to head out to france and portugal. so i will check in with everyone at the end of t summer. >> i would like to say, you know, this is, as you know, karen's last report to the commission and karen and i go way back. i won't say how way back we go. but we are at the d.p.w. and, you know, she worked on a lot of amazing promises and she was working on the clean water program back in those days and there was a point in time in 1996 where she decided to follow the p.u.c. and andy was part of that whole effort of separating er from d.p.w. where her home was and where i was at.

and she actually left and then she came over here and she really was the architect of the water system improvement program because e actually started the project management bureau and she hired a lot of the project managers at the time and it was just amazing the work that she was able to do. when she came over, she said that the p.u.c. had money and d.p.w. didn't -- [laughter] so i followed her lead and when i came over here, to work with her, it was a great -- because she actually helped med get up to speed and then she deded to leave and go work for the consultant for a year. and then she found the light and came back. and then she started working on

the power side, she worked on the power side. she worked on the water side. and so as opportunity actually to run the sewer side, and i thought i asked her, but the way she tells it that i told her. but she came and really dove right in. there is a culture there that the p.m.s and everyone really enjoy working on the sewer system. they have great pride. and i just wanted to say, i give a lot of credit to karen for, you know, bringing the team together. i think the program, you know, the capital programs e really, i thk, especially the latest revisions that we've done.

i feel very comfortable and confident in that and i just want to thank you for that. again, more importantly it is going to be haor me not to see you because habeen working together for such a long time and i'm personally going to miss you and i just wanted to tell you that here today. >> a round of applause. [applause] >> can i say something on behalf -- >> it a public comment on this item? >> yes. >> all right. >> the commission, as you know, karen is one of the few who ve braceds the bayview hunters point community answer i want to thank her for it. but i remember one project which i opposed and so did dr. espinola jackson and those were

the combustion turbines. and i liked karen. she heard us and in the end, that project was killed and we were supported by one commissioner, the ambassador to bosnia, but also a very experienced person in infrastructure and everything. karen has played an important role with a sewer system improvement project and tried to accommodate us, the tituconsts as best as she can. certain things are not her control so i wish her all the best and i wanted to thank you again on behalf of the bayview hunters point community for all of your hard work. god bless you. [applause] >> we're on 7d. >> yeah.

so the last item, just wanted to give everyone an update. as you know, last tuesday the election happened. although we don't know who the mayor is. we do know the results of prop a. and i just am so happy that prop a passed. in fact, it passed close to 80% and that will really help our power enterprise abilities to debt finance so we can invest and continue to deliver power to our customers and i just wanted to thank everyone for all the support and really encouraging us and the board to put it on the ballot. so, again, i want to thank everybody and just really happy that it passed. >> any public comment on what the general manager just reported on? ok. moving on. item eight. >> all right. the next item, recognition of

-- where is he? oh, there he is. tracy, come up. so, tracy, come up, please. so actually tracy has an interesting background. tracy yamaguchi, started her career in 1981. ure i'm correct. and you were working as a secretary for the controller i.s.d. which is now known as d.t.e., right? an84, yowere actually at the airport with the police commission -- airport police commission where you're actually responsible for getting tickets in front of the airport. now back then, they didn't have the security that they had right now, right? >> right. >> and they go and see her and take off. in fact, one took off and hit you, right? d since you decided this is not for me. so she was placed at the p.u.c. and you were working with the i.t. department and you were

responsible for delivering and installing hummingbird, which is a product that i really didn't like. [laughter] but now i see your point. and you also did a lot of g.i.s. support with the gate and c.d.d. and that was something that they really valued. and then you eventually returned back to the help desk and where is you rey helped r cuomers on all their issues and then also you worked on streamlining the process with our mobile device acquisitions organization and distribution and track all of our mobil devices at the p.u.c., which in fact when i had to get a phone because i was going out of the country, at the last minute, someone would show up at my house and here's your phone. [laughter]

so, now i know that during your retirement, you love animals and after 27 years, you are going to snd most of your time. you already know what you are going to do. that's great. but you are going to volunteer at animal shelters and also work at the zoo. san francisco zoo. and you are going to travel and more importantly you are going to sleep. and not wake up at 4:00 a.m. right? so i just wanted to thank you for your service at. the p.u.c. and really, really enjoy your retirement. >> thank you very much. [applause] >> why don't you say something? [laughter] >> i'm not a public speaker, but thank you very much. i really enjoyed my time at the p.u.c. and i'm a little nervous about leaving but it's time to moves on. so, yeah. that's it. [applause]

>> congratulations. >> good. nice. one more. [applause]

>> there any public comment on the retirement of tracy yamaguchi? congratulations and thank you very much for your service. but if you want to see some cool animals, come to my day job. >> good idea. >> standing offer. no disrespect to our zoo neighbors. ok. item number nine. >> item nine is green infrastructure early implementation projects,:monitoring a lessons learned. >> a rough day for the p.u.c. here. we're going to miss karen and tracy y.immens good afternoon. brian henderson, acting a.g.m. for waste water. i'd like to introduce polly perkins who has a presentation for you on the green infrastructure monitoring program which you asked about in the past. and sarah blume who will talk

about the first phase of the lessons learned on the first phase of our green infrastructure projects. the staff in the utility division, they have done a great job documenting and analyzing se efforts so that we can use the results to continuously improve and i think you'll really like the presentations. thank you. >> thank you, brian. and hello, commissioners. my first time up here with you guys and i'm thrilled to be talk about green infrastructure monitoring. >> hopefully not your last. >> hopefully not my last. thank you. can get those slis going, please? >> i'll be updating you on the e.i.p.s that have been monitored to date. they're highlighted here in blue. the wiggle neighborhood, green monitoring.s completed and we've finished the seco

year of the sunset boulevard as well, this season. so each e.i.p. will be getting at least two years of monitoring. and the -- i know summer just started but i live for storm water. looking ahead to the next winter rainy season we'll be monitoring mission valencia at green gateway and green street and once the final phase of the sunset boulevard project is built out, we'll be continuing to monitor there. our two main goals are to evaluate the performance of these projects and build knowledge on green infrastructure in san francisco. we're measuring the reduction in peak flow and storm water volume to determine ithese facilities are performing as they were intended and designed. and we also want to use this information that we're gathering a feedback loop that helps inform green infrastructure project planning and design. but before we get into the e.i..

s, i wanted to take this opportunity to show you the result from the cesar chavez project. this is not an e.i.p., but it is a project that informed our streetscapes synergy program which sarah blume will be talking about a little bit later. this is an opportunityistic project. partnership with the department of public works and it was built before our construction standards were in place. there's a few by retention that are smaller than we'd probably install today. despite that, 'ng really great benefits for our sewer system. as you can see here, this project removes an average of 1.5 million galls of storm water per year and we monitor this project during the 2014-15 rainy season, which if you recall wawhen san francisco experienced a sequence of very large storms that. makes these monitoring results particularly exciting because we got to measure how these build-outs performed during those storms. storms that exceeded the level of service.

a number of the larger build-outs reduced those very large storms by up to 75%. [please stand b

we're measuring just the performance of the green infrastructure itself, correct. good point. so do you have a guesstimate of how much was not captured? we can probably get that, i would imagine. we can look at what's happening around the facilities. but for this monitoring project, we wanted to see how is the green infrastructure itself. i think that's something we should measure because with intense storms, you may get a lot of water and it diverts what gets in there and is fl and water bypasses it. i think we just need to know how effect iive when water ents into it versus how much water can't get in there so that we have that understandings well. wouldn't that potentially have implications for future

design? because if the basin isn't big enough or sloped properly or something, the flotation isn't quick enough. there might be a design that's able to capture more, especially if it's absorbing this much. we do conduct flow testing after we construct eac bio retention planter to make sure that a substantial volume of water ietting into the inlet and not by passing. so that's probably why iould pull up that data to see what flow rates are we putting into these when we're testing them to insure that they're capturing most of the water. i mean, i can verify that yes they are capturing most of the water, a surprising amount. but we can definitely look into that further. slides, please. where'd they go? there they are. this is just another graphical representation of the monitored, measured reduction on the right hand side with 85%, which was much greater than the model predicted

reduction on the left. we attribute this -- this is a pretty substantial difference from what we anticipated. and we think that this is mostly because of the soils drained, the infiltration rates were much greater than we anticipated when we were doing the site investigations and modeling of this project. so, sorry, but that's a pretty big difference. does that mean thatethin is wrong with their model? there's actually a national tren hapdning with these green infrastructure modeling exercises, especially when it comes to the way the water gets out of a green infrastructure facility before it overflows. when you're creating the model, it's lookin at t footprint of the facility and how fast is water draining dow thrgh that footprint. it doesn't account for once that water gets into the ground, it starts to move laterally. and we'll see with the sunset results the difference wasn't that drastic. so the soils along the

panhandle are highly variable. and so we were really conservative with our model estimates to make sure we were getting -- we were building new green infrastructure to manage that storm water. and it turns out we built plenty of green infrastructure to manage the storm water. that's an interesting national trend we've been learning about at the national green infrastructure conferences. a lot of people are seeing this trend, so our data kind of follows along with that, which is interesting. so lking at the sunset model block, these are the results from the first year of monitoring, which was 2016-2017. we just wrapped up mitoring this past rainy season and those results should be ready to share the next few months. again, this project was outperforming model predictions. although not quite as drastically as fell and oak. we saw that the block infiltrated 93% of the storm water that flowed through it during the 2016-2017 rainy

season. which is a very substantial number. i'm gonna reiterate and turn it on its head and say that means that only 7% of the storm water that flowed to the model block went to the sewer system. there's a substantial ruction with these rain gardens. and again, just reiterating the model predictions were slightly under what we measured. and agai thn, whole piece of the soils are infiltrating faster than we anticipated. and the west side, there wasn't as much of a difference as there was with fell and oak. so what's coming up, this upcoming winter we'll be monitoring -- we just wrapped up mission valencia. this upcoming rainy season we'll be monitoring mission valencia, holloway, sunnyvale.

and to wrap up, looking back to when we were first digging into the design and develop mement, looping back into that, the spirit of our goal to build knowledge, all the monitoring reports and data are available online at the website. we're also presenting this data at a number of the green infrastructure conferences across the country. and we're uploading this data to the international database so that other people can look at our data and make the own conclusions. and that's that. any other questions before i hand it off to sarah?

thank you. i just want to say thank you. i'm just thrilled to hear about the performance results. i think that, you know, we as a commission knew that it was some what of a risky venture and it's just really wonderful to see these results. keep up the good work. thanks. hello, commissioners. thank you for the opportunity to present today. per your request, i will be providing an update on the eip lessons learned that we have collected to date. we started this process back in late 2014 using a series of work shops to collect the lessons learned from the different eip project teams and we held a work shop for each specific phase of the project. and through that process, we

collected a lot of lessons learned. today, i'm going to share with you just the top ones and the ones that we felt were most impactful as we move into phase two. our first lesson learned was to establishment cost effective metrics for our green infrastructure projects. d what we did was do an in-depth cost analysis of the different eip project budgets, looking not only at construction costs but also at soft costs related to project delivery. and we took that information and used it to inform our metrics that we are using to screen our capital projects in the next phase. as you can see, we have three main metrics that we're carrying forward. the first one is a minimum drainage management area, which is a proxy for project size. the second is a maximum cost per gallon of storm water removed entirely from our system. and the third is aumim cost per acre of our impervious

acres managed. our second lesson learned is to identify site constraints earlier on in our project selection process. we found that site conditions had major impacts on design and project costs ofeip's. especially because we're building in such a dense environment in san francisco. in addition, our design teams were unable to get accurate information on where utilities were located within the street and other things like that. so moving forward, we're going to be incorporating new utility locating technologies such as ground penetrating radar to get a better accurate look at what's under the street. and then we're going to be doing those investigations earlier on in our project phase. our third lesson learned is to use a programatic approach.

we found that we were able to get very cost effective green infrastructure when we supported other people doing green infrastructure in their projects. so moving forward, we're going to be implementing a grant program to target storm water management on public and private properties in san francisco. and we'll be doing a street scape synergy program. and both of these programs were approved as part of the ten earyapitalplan. but we'll be coming back to you with more details on each project proposal as they are deve.lod it's a separate program, but it is the same approach in terms of being a program. our grant program will be

focused on more larger parcels and performance based green infrastructure. so they'll be required to install technologies like rain gardens and cisterns. our fourth lesson learned is leveraging our key city partners. we found through our experience and through experience from numerous other cities that in san francisco, public and private parcels account for over 50% of the impervious surface that we have. going forward, we'll be focusing our projects on opportunities for regional storm water collection and reuse on large public parcels like schools and parks. and our final lesson learned was our need to develop

standard green infrastructure project delivery processes. when we started the eip's, green infrastructure was very new to our city family. we found that many of our project delivery processesre not appropriate or suitable for green infrastructure. going forward, we'll be delivering standard project delivery processes. we've developed a 65% design checklist. there's a lot more tools that our team still needs, so we'll be continuing this work as we move forward into phase two. u

>> cp questions, how many projects do we have currently? we have our eight eip's and then we have our cesar chavez project. in terms of the whole suite of projects, we now have hundreds and hundreds of projects from the storm water management ordnance. and then we have grant funded projects from our water shed stewardship grants. but the smaest sliver of that is our capital work which is the eip's. so all of these lessons learned will be influencing the next phase of capital work for phase two. and within that, i think we're starting with just two projects in phase 2a, i think. so it will be a gradual roll out. how are we maintaining the current projects that exist? they're being maintained job order contracts put forth. we developed a green

infrastructure labor model so that we could understand all the different tasks, how long they take and who needs to do them. however, we do see that potentially working out like sewer work in a way where we' have a core team that is the crew, knowing that there may be certain specific tasks that we'd have to contract out. we also have ourngicp program, which you all have supported which is underway right now which the training in green infrastructure inspection and maintenance. we're really trying to build that knowledge across the industry so that folks can be engaged in those kinds of jobs.

no only for our puc capital projects, but any smo projects, storm water management projects that may need to hire individuals to maintain the green infrastructure that they are responsible for. public works also? we're partnering with public works on the sunset boulevard project. they're heavily integrated primarily for trash pickup as well. we're finding synergies with their crews out there on sunset boulevard. for drainage specific items and sub service infrastructure, puc is still taking the lead there. but we're partnering on the tasks. and that's one of the things i definitely want to hi highlig highlight. tor s water ordnance on private property, they're responsible for maintaining it.

so we just inspect and make sure that they're actually doing what their permit allows them to do. we're realizing that the green infrastructure is growing and we wanted crews, so i put a crew in the budget. and then the other issue that we're finding is the maintenance. e maintenance is different. now we have a lot of green infrastructure and dpw saying they're collecting trash. instead of being all in the streets, it goes right to that green infrastructure. and i mentioned to the director of public works, he should pay us. now it's just in one spot versus all over the street. but he's not buying that. [laughter] and so we're trying to work

out an agreement to maintain our infrastructure when dpw goes out there. so we're trying to work on that agreement. it doesn't really make sense for us to have crews when their crews are just going right up and down the street. we're trying to work that out with public works. so you answered my questions. thanks for that. i think what i'd like to see, because somebody mentioned that we haven't heard back about the grant program that's gonna be a little more robust. i think this is great work. but when you talk about triple bottom lines and social justice, etc, the jobs piece comes to mind. sometimes what's convenient isn't necessarily what's righ so i'd like to see a little more thought given to that piece. not on the private parcels but

on the public parcels in rticpaar. there's opportunity for us to skill up some folks from communities that we identify as being underrepresented and underserved. put them on a ceer pathway, evaluate their performance, etc. it's not always that sexy. and it's a little harder than just delegating it to dpw. but that doesn't excite me when it comes to career pathway development as much as it does us having that conversation in a real thoughtful and deliberate way as we move in this direction together, but thank you very much. one of the things that we could do is part of the grant process. we're in the process of developing that. and so that could be a criteria. like we had as part of go solar. we had to haveeople from the communities participate. we can definitely talk about and hopefully incorporate some of the stuff in there. i know it's not on a major

scale. this is small. small, yeah. but every little piece that we don't get ends up being a lot that's gone. but thank you, thank you. i'd like to make a comment on that, too. thank you for making those comments. i actually do believe that this could move from a minor scale to a major scale. and i think the work force component is key. the certification program, apprenticeship program. how are we gonna skill up and train up those communities th are looking to get engaged from low income communities that could use opportunities like this. i think there is gonna be a shift as we see some of the am g throu and what does that really look like. i would welcome your partnership. i know that there's been some thinking from the gi team on this question as it relates to

contracting, who's doing the work. is it with dpw, does that make the most sense. what can we do internally. i think there's a very rich conversation. i just want to make sure thdpw, since they're for them to clean t , it makes versus us go to eight different locations. that's one model. the other is that we have job order contract iing until we he staff and actually do that work. i just wanted to make sure you understand that there's intentionality in what we're doing. absolutely. i wasn't actually talking so much about the clean up part as much as green infrastructure as a business. the design, the modeling. it's a whole new business and industry that could emerge that

could provide some real opportunity to the underserved. along those lines, i clearly understand the intentionality and the operational need. and we could skip the whole caathw thing and meet those operational needs. that's what frequently happens. that's why i'm raising it. and i'll just leave it at that. it would be good to update you all thr a memo about the work and how the pilot went. because we're just now finishing it. we're gonna have 20 folks sit for the exam and then we can get back to you on the next cohorts that we'd like to be able to engage in that training. because i think it's directly relevant to what you're talking about. and assumptions get made sometimes that just take us right out of the game. i mean, there's assumptions about cost that are perceptions and not realities. i mean, when you're talking

about skill sets in our industry, in the construction industry, it's pretty clearly set forth what per vailing wage rates are. when you're getting people job experience in the area of general maintenance work, it's a completely different bl game in terms of costs. i'm not sure we've even had those conversations, so i certainly look forward to it. while we have your ear right now, i did want to just clear up one thing that i'm not sure if we're perceiving the same way from the monitoring presentation. polly, correct me if this is wrong, but i want today make sure that you understood the percentages that polly was presenting, such as a 75% reduction. that meant out of all the rain that fell on the drainage management area for one year, 78% was taken out of everything. including large storms, small storms. that's an annual amount. and because most storms are

small, it's able to take out a lot of rain. just want to make that clear. not that it's all going past the inlet. yes? so does that mean that all storm retention is not created equal. is that what you're saying, basically? yes, yes. but i didn't want you to think that it's in each. for a smaller storm, 100% of the water is going to go in and be infiltrated by the green infrastructure. in a very, very large event, not all of it will. if 100 gallons fell on the drainage management area, 75 gallons were gonna be taken care of by the gen infrastructure and 25 would not. thank you. thank you. any public comment on item

9? so, my friend who runs a construction company, bruce and myself, attended the very first work shop on green infrastructure that was held. one of the first things i noticed was there wasn't anybody from the community. all of the people that attended this work shop were contractors. and the work shop was given by consultants. nobody from the sfpuc. after that, there was no follow up. we passed the test. apparent they have a list on some website. we weren't given a certificate.

one of the concerns of the contractors was that in the united states, theresn't niko that produces the material, the pipes, the suctions, pumps. most of it comes from china. so when we talk in this grand scheme of things, and if you go to the bottom and see who really constructed whatever was constructed at cesar chavez or who really constructed the stuff on valencia, these are contractors who more or less did it without a baseline pl plans. now, there was one frame there

that says sfpuc is going to do this and this and this. but they cannot do it all over the city. it has to be incorporated in removing all the concrete in front of your house so that we do it just like they don advanced countries, okay. all of the greening that was done in the visitation valley wasn't done by sfpuc. thatwas done by grants, by people getting other contractors and doing it. whenever we talk about this, the main thing is as one of the other commissioners says, it's work shop, work force and equity. they talk about equity a lot. but when it comes to this type of what i started a long time

ago, we had equity to give people a good salary. thank you very much. thank you. any other public comment on item number 9. next item, item 10. item 10 is an update on federal legislation and appropriationselevant to the sfpuc operations. good afternoon, commissioners. my name is emily and i'm the ctor of policy and governor affairs for the puc. i'm here today to give you an update on federal legislation appropriation. washington dc is currently consumed with issues involving north korea, iran, venezuela, immigration, international trade and most importantly, at least in the eyes of congress, the upcoming midterm elections. so in the energy and water space, the administration is fixated on providing government

intervention to assist struggling coal and nuclear power plants, altering a host of environmental policies and programs initiated during the previous administration and expanding opportunities for energy production and export. importantly to us, the water resources development act is of theislaegve items that is likely to move this session. it's reauthorized every 1-2 years. and it is meant to improve the nation's water resources infrastructure. the house bill passed hr8 last year with bipartisan support. the bill was narrowly focused on authorizing individual u.s. army corps of engineers water resources projects. and senate bill s-2800 is awaiting floor consideration after passing the environment and public works committee. now, the senate bill is much broader and includes many items of interest to sfpuc. but today, i'll just highlight two major areas, financing and

work force developmen an al. this is a modified version.

weork w really hard for the last four years to create this program in partnership with the water agency leaders alliance and the national association of clean water agencies and the u.s. water alliance and oters. we have been working closely with senator booker's office who recently sponsored a stand alone piece of legislation to promote this. and who is a key champion in this issue area. and we'll continue to track that particular piece of legislation to see if it can make it into the bill or other pieces of legison. on the appropriation side,

congress' most basic and pressing function is to exercise its power of the purse to fund the federal government. however, for more than a decade, congress has failed to pass the 12 individual appropriations bills necessary too so in a timely, efficient or predictable manner. in large part, this failure is due to the increasing politicized atmosphere in dc and they now have a trend of including authorizing language, ie policy writers and partisan report language on appropriations bills and their elimination of congressional earmarks.

for his part, senator mcconnell

recently announced a return to regular order by focusing on appropriations bills and moving them through the senate committee and floor. the appropriations bills currently under consideration ginning october 1st 2018. we're now working to insure that the energy and water bill includes funding from the army

corps. the senate bill will be marked up this week and senator feinstein is the ranking member of the interior sub committee. the last bill is forhe commerce justice science and related agencies bills.

democrats opposed the amendment but it passed by majority voice vote. the bill now goes to the house floor. we'll continue to track the appropriations process as it moves forward this year. and i'm happy to take questions.

i have a question. that was a lot of information. thank you very much. so the national fisheries appropriations bill, what are the implionf o that not passing? that's passing? i think michael might be better position to answer that question. do we want that to pass? sorry -- that's all

we have had a conversation with her staff and she's just being briefed now and we don't know what her position will be at this point in time.

so our team is briefing her? her staff is briefing her. her staff is briefing her. but my interpretation of what i just told you is the same interpretation i've

i don't know where we are with that. i'd love to get an update. i know we got a note from the river trust on their response to the alternative. i kind of would like that to have a more robust presentation and conversation through the chair.

i'd like to call peter mangarella for public comment. trout unlimited is a private non-profit organization dedicated to preserving, precting and restoring north america's cold water fisheries and their water sources. i'm a board member of the north bay chapter wh includes the city and county of san francisco and the president of the east bay chapter that includes alameda
