have clarence of our playground equipment. >> no. >> i'm talking about power washing how do we clean our equipment and it's surface cleaned by backroom or brush dry wiping it down but the power washing even before the drought it on came into play if it was needed. >> how often do we clean our playground equipment. >> the custodians are through everyday for example, the sand is swept bag into the sand area by in terms of like i said the wiping down of a play structure is only for the places that needs it. >> is that complaint driven or do we check the equipment

ourself. >> the custodians they walk through and technically check it everyday and keep it clean. >> so we have is enough staffing to check our playground equipment everyday. >> yes. >> it come up because our families and our folks that use the macaulay playground one of the concerns i heard there of the moths and other things that tend to collect underneath the structure not on the ground they said from their observation it explicit look like it was being kraendz but the leaves are swept off so when you brought this up i was curious about our routine for cleaning the actual equipment and advocating for that i want to understand what we can tell our residents in the regular maintenance of our play structure. >> yes. we meet with the

playgroup and the moth issues was brought up on the tiles the port in place can accommodate moths so they brought that to our attention. >> thank you, thank you so much. >> thank you, sir. >> i believe i'm followed by the department of the environment. >> good morning, supervisors supervisor wiener i'm a green building specialist with the environment department i help with the building inspection and talk about how they fit if with the other financing and other

city issues on the financing front san francisco as you are aware is operating an energy program to provide finance for not only the seismic retrofits but the water efficiency in this projects in multiple family commercial buildings today it's not being used that way but this year's there a significant mechanism for the efficiency prudence on the policy front san francisco maintenance a san francisco building green code in essence is the green code known as cal green and the leadership labels like efficiency and also a number of different specific local policies those put together the san francisco green

code and ward to in door water consumption the most daily element is over the last few years the state has constituted through cal green as well as similar policy efforts at a city level a requirement that all fix furs turns and fittings in the orderly and new buildings as well as a fixture served we need to upgrade those and the upgrade is 20 percent more focus than required in 2008, san francisco also maintenance the commercial water conservation ordinance and the emergency conservation ordinances together with the water requirements that include the main difference between the state legislation and the local is the while the state

legislation has quadriplegic with san francisco san francisco requires all inefficient structures to be retrofitted in new contradiction the city in large new commercial buildings asks for an additional 10 percent efficiency threshold over 20 percent over provide codes with initiative dine and all new commercial building that includes the water review to make sure they're operating under this code. >> so again a little bit more detail because we're asked to discuss water sub metered dollars a state requirement that requires indoor excuse me. sub metering of tenants in

commercial buildings provided their say either a new building of entire new uses or an additional existing of 50 thousand square feet in that case meters will have to be installed for every tenant use so one hundred glances a day roughly 78 occupants in this space there are feasible back up systems that serve ero tenants spaces we run into a unique challenge san francisco is one of the few cities that has significant square footage since 2010 when the policies were impacted so there's been a can you think drum of whether or not theres tenant space built by the owner with the continuation of largely out the space so that issue of

interpreting that code that ups the metering to occur the rented spaces or another spaces serving tenant needs has been argued successfully by the development community to be implantable because they haven't leased the space. >> back up the stating requires the individual metering for commercial larger commercial building but not for residential. >> that's right. >> that could be problem number one there's no requirement in terms of the eco the mega residential buildings and absolutely no remit building one thousand believes go that you meter. >> yes. >> that's number one so you're saying under state law commercial multi unit for lack

of a better word 50 thousand square feet or more have to be metered for tenant use but developers are building the buildings and saying right now, i'm pulling the permits there's no one accompanying is so i can meter the entire building because no attendance there. >> yes. >> has there been an effort to close that loophole. >> ooirm of one. >> has the city taken the position that that's the interpretation that is consistent with the intent of state law? >> not to my knowledge i mean, i'm in an walked position the department of building inspection maybe. >> maybe i'd like dbi to address that i would hope that that could be

in not corrected by the state legislation we could correct that locally above and beyond seems like the state protective passed that law and if anyone objectives to it but clearly with the the president with the large building it is vinld meters it's not happening here because of a loophole or possible loophole that seems like a bad result. >> it is enough for a small adoption and so it's a

regulatory you instrument so that requirement was not spefg impacted by the legislation. >> by the the state thank you. >> so when we're done i want mr. kelly to talk about that. >> the last couple of food for thought is that is this requirement we've gone over this is not operating as tint is only applicable to new buildings and new yoiksz that are buildings that are required to have the most focus requirement it is one the things it's not targeting the existing stock with the greatest surveillance on the other hand the assumptions it is much more likely the plumbing will be difficult to meter because not being a single point to necessarily meter anything one. >> this is more for dbi but in terms of the existing building i know from converting from existing buildings whether residential or commercial it could be expensive to remove the whole plumbing system but a variation in terms of what a building was built for example, is it easy to ryan white a 1995 building over a 1905 building or relevant. >> i'll get someone to answer that and yes. >> i thank you. >> i'll be happy to answer any questions. >> great, thank you so syria the chief plumbing

inspector is here fill us in. >> thank you for the invitation i'm the chief building inspector in san francisco with wards to the buildings of 1905 to 2005 it depends on the the law outs so unfortunately, to is it's easy to revving a san francisco environment commission 1278 it's not easy especially, if you have might want floors if you have 20 floors and stacked unit and running the water mains up parallel for all the units it's possible impossible to take out one specific unit and meter those two units because the supply is coming to into so the meter you have to have a apply from one spates and branch out

and connect those units going forward through i think we spoke with the puc and they've enlightened we on the fix yourselves for supplies instead of putting in a huge meter but i'll let me let them speak but easier to meter for some units or apartment or occupants or anything back to your question of interpretation unfortunately, when people come forward and come as one tenant we see one tenant there when their metering that one that group it is hard to turn around and say how many floors is a tenant going to take you might take 5 and i 5 and

someone else takes 5 floors. >> if i'm the developer come forward and their building a 70 foot story it's not going to be one tenant maybe one hundred and 50 tenants or 45 attendance but court of appeals there is going to be quite a bit of tenants. >> what's happening is people coming down and saying it's a new building and we're moving forward and i and i'm the only tenant i have my meter 0 therefore it is basically you're seeing what the meters are meeting what's required then they get a final completion it's an existing building. >> it didn't meet the intent maybe it meets the letter. >> yes. >> but the intent was that in

the large new commercial buildings there is individual meters so the businesses will have an incentive to save water. >> it should be metered for every floor. >> so you get the push back from the developer saying or the owner saying well, there are not tenants in there now we don't have to sub meter it has the department pushed back and saying we'll require you to meter it. >> no. >> one of the other things i've got 20 floors do you sub meter one floor and the others i'm at large out all 19 floors and one for myself i don't know who is going to be on the floor so you sub meter every floor or who is

at large if i'm leasing 5 floors you're using my usage so they're saying if you're you're going 3 or 6 or 9 who do you sub meter i think every floor should be sub metered. >> has the department taken the position they could push back. >> we could go for a code change. >> under the current code you don't have the basis. >> i think we have to have a new code. >> we could pass a local code ordinance to basically go beyond what the state rule requires and yes we could. >> we're going to look at that serial and reach out to the developing community there's a clear intent it's been clouded i think the department is in a difficult position i will

encourage you to you know if there's a way to look at it and pushing back to do that that makes sense. >> the other issue i have on multi dwelling units of one hundred and 50 or 2 hundred units that's a hard thing to do because of the lay out developers the way a they run their water and you almost have to be sub metering every floor you'll be sub metering every unit not floor that comes into play we should know what is exactly being used and who is wasting or using too much water but breakdown that as well to put it out there. >> i know there's complications you've talked about those but with the electrical i know that

electricity is different than plumbing it seems like something theoretically will make a lot of sense. >> yes. >> thank you very much okay are ray we back to the puc now or? >> good afternoon can i have the slides please i'm paula with the san francisco puc i have a bag of examples with me just waiting for the power point. >> take your time. >> you're all set. >> thank you so in addition to our drought response actions the san francisco puc's is dpifs

portfolio we have developing a water supply in san francisco our wide range of conservation services makes to eel easy for householders to reduce theirs water me over shower heads i've brought examples to share with you as well as our computes the showerhead we've talked about the notice he lives giving away for free to businesses and residents in san francisco. >> can you talk about in terms of what is giving away for free. >> a spray notice he will and showerhead and areas for the boardroom and the kitchen closet. >> the toilet leaks so i think

you know, i think what would be useful all the supervisors have newsletters to send a paragraph or two to the offices to put out 20 our constituents so people know this is free. >> we would like to provide samples to our offices. >> and residents can come to our customer service center building to pub pick up the fixtures or call us 4155514730 as well as our website water conservation at water sf.org multiple ways to reach us. >> will they be e-mailed to people. >> we don't e-mail the devises. >> we also work with residents

and businesses with the system using water with outdoor water irrigation and the water program in early 2015 we'll resume our rain bar restraining order for residents to collect and use rainwater we offer our customers rebates for high fix few years turns like toilets for example, a rebate for an old toilet we'll provide a rebate up to $125 during the past year over 25 hundred rebates and over 27 thousand water function turns including the showerheads to residents and businesses and our conservation team had over 4

thousand surveys to help the residents be more water effect today, we're 49 glances of quart per person per day one of the lowest rates per capitalizing capita in california we have local rental to reduce the demands the conservation ordinance that requires the installation of low function turns and showerheads upon the sales of the residential properties and you'll commercial properties must comply with the ordinance by 2017 we we have the san francisco efficient ordinance that requires the new landscaping to have a new irrigation system, however, as we talked today conservation

today is not enough we're developing nor local supplies in san francisco this year we broke ground after a decade of research to insure we can safely different our supply without kcmo our water we've partnered with rec and park to irrigate harden park golf course and saved over one hundred and 50 million gallons of water we've recently completed the sharp park at the next the oceanside to irrigate golden gate park lincoln park and portions of the presidio. >> when p will that be complete. >> we anticipate it to be 2018 but looking further to expand our portfolio we've turned to

non-traditional or alternate water sources to have alternate waters supplies like gray and black and foundation water drarmg we've incorporated the living machine to treat the gray water and use the threat water to flush the toilets during the past two years we've reduced our water saving 2100.6 million gallons and to encourage others to it treat and use alternated water the board of supervisors passed an ordinance last year to allow the collection and treatment of those alternate water sources it's implemented with the partnership with the san francisco puc or department of building inspection and the department of public health and to date over 20 projects to

treat a variety of alternate water sources puc collection information on the water faucets we'll provide up to $2,150,000 and others for sharing watering i'm going to turn it over i'm going to turn it over i'm going to turn it over i'm going to turn it over to sfich to conclude. >> other possibilities 20 projects that are using for non-use of water within the buildings that's one possible area to explore more those people are voluntarily going it it liking looks at like a good thing to do and the saving associated with the installation

of on site water multiple sfnldz and have the tools to make that happen it's one possibility and certainly help to educate the developers about the non portable 0 act. and over all we're, of course, looking at more conservation there's a little bit more you can do not enough to fulfill all the needs more recycled water but on a larger front looking at new uses of water transfers with other entities when everyone is short another way to have a conservation is to get through a biblical drought that will be an attractive item as well as the last item on the list to direct

water and that's one that is untouchable but more serious research into the potential for directed use of watering so we're involved in looking at those things we know that as progressive water that's what you need to do. >> direct that means not coming from a recycled water plant but inside our own home. >> no taking water from the ocean control plant and treating it and pitting that into the drinking water distribution. >> in terms of water recycling where do you see us heading in the next year's there's a lot of challenges in terms of you know obviously we're moving forward

with golden gate park and 45r8gd park, etc. but in terms of homes there are a lot of challenges around the plumbing and doing separately plumbing systems where do you see us in terms of large-scale water. >> on first of all, individual homes we think are problematic it's hard to do on an individual basis the plumbing is going to be installed to protect that believe that's why we focus on commercial and single-family homes to protect the folks in the long-term so in terms of the recycled water and the dent in water supplies the true answers

in suburban you'll are treat it to a certain level the water spends 6 months in factual and the natural portal water then treated to a much higher level and inject it into the drinking water system looked like if it stays dry that is a consideration. >> is it being used. >> it is being done in different countries around the world that have like san diego has been looking at that to come up with a feasibility assessment and draft recollections for what would be considered acceptable for quoteable use for 2 years.

>> that's a psychological barrier but science will have to come up with that. >> that's the urban touchable but approachable in conversation now. >> in terms of sub metering or individual metering unit i know that is something we've decided there are code challenges and challenges around cost particularly in existing buildings but especially in a place like san francisco where you know largely people in multi you unit buildings when you start imposing a announced 10 or 20 percent it's challenging to be that it's one thing in a
