50 horse power, and between tier one and two. you would reduce, particulate matter emissions which is the major concern in the city. and finally the tier four, final and then is just became available last year and it was reduced another 90 percent, and so that is all, with the new engines but a lot of, construction and equipment, and lasts for 15 to 20 years or beyond, and so, there is another strategy, that is verified by the california or resources board, where you can retrofit, the existing engines which will or can reduce the emissions up to 85 percent.

and so, although, the existing ordinance was great, you know, being a progressive city that we are, and realizing the newer technologies are becoming available, we felt that we could maybe, do more. and partially what was pushing us to do more, was through the california environmental quality act, and that is really where the planning department has stepped in and we are often finding out that the public works projects were having to do additional modeling and or do modeling and have to do additional measures, beyond the existing clean construction ordinance to comply with sequa. and so, we did not really feel that that was the most efficient way of doing the development and review, of the public works project and has to compile the ordinance and then

the sequa has to do more. and so us collaborating with the department of public health and we went on an extensive modeling effort to map the areas in the city that have the most burden from the air pollution and that is what this map shows and the blue areas are and i am not going to go into it too much and i am happy to answer the questions about it, but essentially in these areas of the city, we think that there should be additional measures to protect the public's health, yes, commissioner? >> could, i ask a quick question, this the air pollution, associated with the construction as a sector or all air pollution period? >> great question. >> all air pollution and, this is based on all known, modeled source, or all known sources of air pollution, stationary, sources, roadway sources, and as you can see, 101280, and

clearly olining on the blue. >> it definitely matched the construction, i mean, rather a transportation corridor and highways as well as some of the most heavy developed. >> yeah. >> and so, just quickly, on the roadway sources are the primary driver and there are two criteria that go into the snap and pm 2.5 small, particulate matter as well as excess cancerous, and the low ray sources are the primary driver through, you know, kind of when the corridors and to the north east water front, and the maritime sources are a big driver and the stationary sources are also a big driver, and from such of back up the diesel generators that you see on a lot of high-rise buildings or industrial sources, and this map, would look different ten years ago, honestly with the power plants in the city, and but, the roadways i would say are the primary generator.

>> and so, with that, we needed to figure out what was feasible, though, as additional strategies to impose on public works projects and this one comment, this mapping, and this modeling is part of a larger city wide effort collaboration. and where we are trying to reduce the burden of air pollution, both on the existing and in the new developments in the city. and so this is just one strategy, among many including looking at private construction projects in the future, and commissioner had a question about that at the policy subcommittee that we are working on through a larger city wide effort. and so, in, and this is, my title, got thrown off somehow. but, this chart was one of the first things that we looked at in trying to figure out what is feasible, as indicated earlier, there is here for the new

engines are being, manufactured for the tier four, but this graph shows that new engines are largely correlated to the economic growth and we are starting to see a lot of new engines in the air basen for contracting and this is just construction equipment. >> and purchasing the new engines and the manufacturing and warm. that is tier one and tier two, engines and approximately, 47 percent, of all engines, in the air basen are tier two, or better, and tier three or four and but only two percent, are tier four interim and so that was kind of a first indication

that, you know, we would love to require to the tier four but it is really not feasible at this time. now, an indication of cleaner equipment, being greater demand is by this pi chart and the green, purple and the blue are 2, 3, 4, and although, they only count for 47 percent of all engines in the bay area, they are being used 59 percent of the time. and this, this pie chart shows that, you know, once again they are used being 59 percent of the time and they are only 32 percent of the pm emissions and so the equipment is much cleaner than the older pieces of equipment. >> and so with that knowledge, our proposed updates to the ordinance are pretty simple. and we are proposing that within those limited areas of

the city, we have an additional requirement. and so, instead of the chair two, or the verified diesel emission control strategy, we say tier two end. and these, emission control strategies and they are available, for all different types of engine sizes. and so, if you put the tier two on top of the vdeck you are reducing the emissions almost equivalent to that tier four, final which is not yet available. and so the other aspect, that in those blue zones, they are proven exposure zone and there is the plant to help out the department and the public are assured that these projects are actually complying with the requirements of the ordinance. and i will touch on that in a second, here. >> and so, again, this is how protective and this is the tier two, and i already kind of touched on this, but combined

the emissions reductions and compared to the other equipment, is a much cleaner, and this is consistent with the sequa and i did not, and and lastly, it provides a greater ability to monitor for compliance, and this picture here, is highlighting these red stickers on the construction equipment. and this is now required by the state law, that all construction equipment is supposed to have a sticker on each side, and six characters, and you can write down the six characters and go on-line, so that the resources board website and look up the equipment and see if it is actually meeting the ordinance. and we will tell you if it is tier 2, or 3, and that is the public m not do that. and and we will help the agencies monitor the compliance and so over all, and we just

leave that up and the ordinance will be more health protective and we think that it is continues to be feasible, and they are really protecting the workers and the residents and so i am happy to take any questions and we don't know if i mentioned this, but i asked for your support and i need this resolution. >> thank you. >> thoughts in commissioners? >> yes, so this, item has been before the policy committee? we had a thorough discussion of this. and we, i think that i can speak for all of us, i certainly can speak for who is not here, but i think that we agreed that it was addressing a very important environmental issue and then it was an

excellent example of data driven, adaptive management, using the sequa process and so i hope that my fellow commissioners will in fact, approve this proposed resolution. >> thank you. >> commissioners, colleagues? it sounds great. it sounds like we are going to get an increase in the environmental benefits from a program that is already doing that, and serving to bolster the national leadership on this and perhaps we can get a motion to approve. >> i move. >> so moved. >> second. >> and is there any public comment on this item? all of those in favor of approving the resolution to support the amendments to the clean construction ordinance? >> please say aye. >> all of those opposed? >> none, thank you very much. >> and the motion passes. >> thank you. >> thank you, for your

patcinece tao. >> so we are skipping 7 and 8 and maybe we can move to number 9 >>review and approval of draft resolution 2014-07-coe commending acting director david assmann for his service to the department of the environment, commission on the environment, and to the city and county of san francisco. (explanatory document: draft resolution) sponsor and speaker: commission president joshua arce (5 minutes) (discussion and action) >> in your packet is a copy and the commission, joshua acre and this is a discussion item. >> thanks, and i feel like it was, a long time ago that we had a big sigh of relief, because we thought, oh, we well have got david until june, or july. and you know? and well it is like we have a lot of time. and we can get a lot of stuff done. and we have got a lot of stuff done. we did a national search to find our new director and we are all excited about that.

june second. and we got a chance to spend a lot of time with david during that and it was great. and we got to talk about birding. and i found out that there is not a bird that you can't think of that you could throw his way that he does not know and like when i asked, about the cinaloya ran. >> yeah. >> and you know, it is all of that and he is so respected and we thought that it was the least that we could do to look at his accomplishments of what he has done at the department and he is one of the originals at the department of environment and it goes all the way to the beginning. and he has accomplished a lot in the different roles that he has had and he is an institution and maybe one of the things that we can do before we kind of share our thoughts about david, is maybe to hear the resolution and maybe monica can read it just so that we can put it into the record everything that you have

accomplished in all of these many years at the department of environment. >> resolution, for his service to the department, the commission on the environment and to the city and county of san francisco. and whereas stated he started working with the city and county of san francisco of administrative services on july, 1, and 1993. and then, with the department of the environment as deputy director on august 20, 2001, and to june, 30, 2014, and as stated and he served as the director of the department of the environment from august 16, of 2008 to august, 9, 2009, and as february, three, 14 to may 31, 2014 and was david created and sustained the environment now, program and the second environment jobs practice and as david was the role for the

department to 2011 and as he was responsible for all personnel issues in the growing department and whereas he also directed a budget that grew from 777,000, to 20 million and whereas he eliminated the department, for the general support, while securing other sources of funding for ultimate of the departmental programs and was david for the implementation for the environmental justice program the largest in the country with the grant budget of 13 million and responsible for upgrading the departmental, offices, and from a single floor of the 11, grove street to the show case of 1455 market street, and whereas david coordinated the department of the environment role in the gender analysis under the implementation of the cew, 8, and wedaw, and conventional of the elimination of all of the forms of

discrimination against women and whereas he played a leading role in establishing and maintaining the california, stewardship council and whereas he played a leading role managing the green cities california and a state wide coalition, and whereas he was instrumental in helping san francisco achieve ground breaking programs, such as the program and the energy and climate programs and, toxic reduction and the out reach program and the clean transportation program and whereas he served as acting director with the department of the environment on four separate occasions and whereas he was established a city first bio diversity program and provided the support to the staff throughout the transitions through the years and whereas he has continued to direct the program, and under the mayors, and was he will be retiring from the city and

county of san francisco on june 30, 2014. and now, therefore, be it resolved, that the san francisco commissioner on the environment come mends him to the contribution for the department of the environment and the commission on the environment and the city and county of san francisco and be it further resolved that the san francisco commission on the environment wishes david assmann well on his future endeavors. >> let's hear it for david. [ applause ] >> thank you. i really value all of the years that i spent with the department, and with the commission, and with a growing awareness of all of the issues that are important to the residents of san francisco. and i see the future of the department, and the environmental issues as being one that will continue to grow

and that there is a bigger need than ever for the leadership in this area. and that i feel honored to have been able to play my role in helping to move these issues forward. and i think that the department remains in great hands, and i look really forward to seeing the achievements that will come in the future, and i think that our new director will do a wonderful job and i think that we have a dedicated staff and i think that we have the secure core of funding, and i just, this has been a part of my life for more than 20 years. and it is going to be hard to say good bye. and i am not going far, and i will still be in the city and i will stay pay attention to what is going on. and i will still be available, and meet with the people periodically, to talk about environmental issues and contribute to whatever way that i can. and however, it is time for me to take another phase, and i like to say, i spent many, many decades working for the

environment and now i want to go out and enjoy the environment and so i appreciate the accommodation and the support that the commission has always provided from day one, from the day that i started working with the department, and i felt that the commission has always been very supportive, and appreciate being able to work with each and every one of you. and so, thank you. >> thank you. >> on the resolution, we do have to add the fourth date that david served as acting director. >> and we have to. >> and that the fourth one? >> yes. >> well that is i will tell you a story about that. >> vetor recruited me to be the deputy director of the department of the environment back in 2001. and i was all enthusiastic, and came to the department and got all of these plans and started working on a number of project and about four months after i started she came to me and said that i have the news for you

and i am leaving the department and so, just after i started, that was the first time that i became the acting director was back in 2001. and so shortly after i came over to the department. and when it was, and the department was with the eight people and that was the 8 and there were 7 people when i joined the department. and so it is obviously seen tremendous growth, i mean, from what it was in those days to the point where we are now having the hearings in the board chambers and we have 111 people on staff and a budget of $21 million and that was beyond dreaming in 2001, and and it was and i would have a chance to kind of see the way that your experience and values is

part of what we are looking for in that next direct and her so i think that it is, you know, obviously, everyone is going to remember you, and think you for a long long time and i think that it is great to remind us that you are just a phone call away, or available to sit down for lunch and we will pick your brain and we will take great value in that. colleagues? >> i got an insight into what a pleasure it would be and we were looking for the out reach director and i went through that process twice as it had been and what i remember very clearly at the time was really appreciating that your blend of just solid insight and true environmental commitment that just shown through everything that you were doing and but also, just the relaxed love of

what you were doing, and to sit in your office and interview the people surrounded by the birds, and you know, it was sort of like being out in nature and inspiring and i appreciated that in the introduction into the department life and we will miss you a lot. >> thank you. >> commissioner wan? >> sure. you are really one of the person in the department that i could go and ask the question, and you really know the department inside out and the history that brought the knowledge that you have really inspiring me. and i really wish that you could stay longer so i could learn more from you and i am also happy for you because it is hard to enjoy the environment and we will hope that we will continue the spirit that you have and the solid work and you will be a real for the department. >> thank you. >> i think that so much of this department, combines, sort of actism with being a government agency and kind of all of these beautiful, and all of these

problems with that but there is also a beauty do that and i think from the very start and even when i was not around, you kind of exemplified that and kind of having really started at and i just got to know this recently, and at one of the great activist publication and having sort of come inside and into the government in keeping that role of the department within the city, family and, making sure that everybody else and sort of was still towing the environmental line and pushing it as far as it could. and so i think, you will be, sorely missed and i will certainly miss you and i hope that you write everything down that you know. so that... >> i am going to give 2,000 e-mails that i have safed to my successor. >> thank you. >> commissioner wa*ld? >> thank you. >> and david, i am the longer serving commissioner but i know where i have barely scratched

the surface of the time that you have been here. but, i have been here long enough to really see, the impact, that you and your values and your compassion for the environment have had on the department not just in terms of the role in the city but the way that the people do their work, the way that they relate to each other. and the way that they relate to us. and then, you have, not only had these incredible accomplishments that are listed in concrete accomplishments that are listed in this resolution, and but, the impact that you have had on every single person who has dealt with the department either directly, by interacting with

them, or in directly through their interactions and which the staff members which you have mentors and inspired. and motivated. and it is true that the department will miss you terribly but as a recent retiree myself, i cannot even question your decision. although i did for a period of time, but i stopped now, that i have actually retired and i hope that you have a fabulous next stage of your life, and that you get to enjoy the environment as much, well, as much as you possibly can and it can never be as much as you deserve to. thank you. >> thank you very much. >> and thank you. >> all right, any public comment? on the items? seeing none, the public comment is closed. colleagues, perhaps, just for housekeeping, we can get a motion to amend our resolution, and commendation to reflect the

number four? that monica mentioned and that was on page. >> it was on page 1. and i moved and second on that? >> second. >> and all of those in favor. >> say aye. >> aye. >> opposed? >> all right could we get a motion to approve the commendation? >> i move that we approve the motion of commendation. >> all right, so moved the second from commissioner stevenson and, all of no, sir favor, say aye.. >> aye. >> opposed? >> thank you, david. >> for everything. >> monica if you could call the last items, 14, 15, 16 combined. >>announcements. (information and discussion) 15. president's announcements. (information and discussion) 16. new business/future agenda

items. (information, discussion and possible action). >> on my end, any announcements in the future agenda items? >> thoughts? >> commissioners josefowitz? >> i just want to thank our dear president for organizing what i thought was a tremendous joint meeting. and we have been here for a very long time now. and not as long as that longer meeting that went on for bloody ever. but, for the pleasantly for this time and thank you very much for organizing that i think that it is tremendous that we can do some more and i think that there are exciting things and opportunities that came out of that. >> glad to do that and, thank you for the feedback. and you know, you sit there through a long meeting and you are wondering, how we are doing and so, we appreciate that commissioner. and commissioner? >> i would like to suggest, that we consider inviting roger kim from the mayor's office to come to maybe even our next full commission meeting to discuss with us the mayor's

environmental priorities. >> okay. >> we can do that. >> and one other announcement is that, i said that i don't have an announcement but i do, germ o has been working like crazy behind the scenes to coordinate and i notice that he has been here this entire time and thank you, for everything, and for making this happen, and david, and the team, and you know, it was not easy and of course, you know, i hope that when the city attorneys get assigned to the commissions it is not just like, rolling the dice or lottery, and it is like subject matter. and that you know, that tom, and when he is here on a night like this, it is like, he is, you know, the environmental, stuff that we have talked about just like, we that he thinks that he is so glad that he is here to be here for a long meeting like this. and i might be right? >> yes? >> okay. and thank you, we don't often thank you on a night like this and we have to and of course, monica and she is running

around this whole time and fixing the technology with our friends at sfgtv, and thank you. >> thanks. >> and okay. >> any public comment? >> i just have one quick thing to mention is that there is a temporary new temporary system for the new director, ryan jackson who will be getting in touch with each of you to set up an individual meeting with debbie for hopefully next week with each of you. >> so if you hear from ryan jackson, he is debbie's new assistant. >> okay. >> all right. thank you public comment? >> seeing none, public comment is closed. >> item 17? >> public comment, on items not on today's agenda? >> any public comment? >> seeing none, it is closed. >> adjournment, 8:10. we are adjourned. thanks.

♪ >> i am so looking forward to the street fair tomorrow. >> it is in the mission, how are we going to get there? we are not driving. >> well what do you suggest? >> there are a lot of great transportation choices in the city and there is one place to find them all, sfnta.com. >> sfmta.com. >> it is the walking parking, and riding muni and it is all here in one place. >> sitting in front of my computer waiting transportation options that is not exactly how i want to spend my saturday night. >> the new sfmta.com is mobile friendly, it works great on a tablet, smart phone or a lap top, it is built to go wherever

we go. >> cool. >> but, let's just take the same route tomorrow that we always take, okay? >> it might be much more fun to ride our bikes. >> i am going to be way too tired to ride all the way home. >> okay, how about this, we can ride our bikes there and then we can take muni home and it even shows us how to take the bikes on the bus, so simple right here on my phone. >> neat. we can finish making travel plans over dinner, now let's go eat. >> how about about that organic vegan gluten free rest rft. >> can't we go to the food truck. >> do you want to walk or take a taxi. >> there is an alert right here telling us there is heavy traffic in soma. >> let's walk there and then take a taxi or muni back. >> that new website gives us a lot of options. >> it sure does and we can use
