hours, one before? that is not before us, and i don't mean to put you on the spot, but you reminded me that sometimes is a challenge. we don't give that much of a preview of what are things to come. i'm wondering, is that something that you think we should start looking at as well, too? >> well, the brown act requires us to post things 72 hours in advance for regular meetings. that is something that we do. in addition to that our administrative code says that special meetings are posted 772 hours in advance. it's difficult to get something out before that and working with the committee chairs as well as coming to the board agenda, it's very difficult, you're working up to that last minute to get that stuff posted to meet those timelines. >> i know that's a different subject and a different piece of legislation. what it does is it sets the floor, it doesn't set the ceiling with regard to how much advance notice that we provide.

i think to many departments, i think that is worthy of a further conversation. thank you, i appreciate it. colleagues, i also just wanted to let you know that we had guesstimated based on the budget of what the city does spend on the current practice of notification that the office of contract administration guesstimates that we would spend $346,000 in 2010-2011 and that by us moving together the strategy, not only will we be able to increase i think access to information and notification toward the citizen ry on all fronts and modernizing the tools that are already in the city's assets and underutilized currently and newspaper notification, we're still realize a savings of $200,000. in the scheme of things, it

looks like a lot of money, but right now we're looking for every nickel and dime that we can in the fourth year of this deficit. supervisor campos: legally every individual has to be given the same amount of time. so you get, so you get one opportunity. so those are the rules, i'm sorry, thank you very much. supervisor mirkarimi: i'd be happy to take a question afterwards, if you like. supervisor campos: we have some amendments that have been introduced. before we act on the item, can we have a motion to adopt the amendments. supervisor mar: so moved. supervisor campos: take that without objection. on the underlying item, if we can have a motion. supervisor mar. supervisor mar: i move this forward as a committee report on the december 7 board meeting. supervisor campos: great, i would ask if i could be added as a co-sponsor supervisor mirkarimi.

supervisor mar: i would like to as well. supervisor campos: if we can take that without objection. supervisor mirkarimi: i would like to thank everyone that came and waited on this. supervisor campos: thank you very much. madam clerk, if you can call the next items. >> items number 8 through is 1 are regarding existing litigation. would you like to adopt the motion to go into closed session with the city attorney. supervisor mar: so moved. supervisor campos: we have a motion by supervisor mar to go into a closed session. are there any members of the public that would like to speak? seeing none, that is closed. we will take that motion without objection. we would ask the clerk to clear the room so that we can go into closed session. again, thank you all for coming out to the rules committee meeting. 6

supervisor campos: we are back on and before we turn it over to the city attorney, if we can get a motion not to disclose the closed session discussion. so we have a motion by supervisor mar, if we can take that without objection. mr. deputy city attorney. >> on above of the city attorney's office, i want to thank the committee moving forward with items 8 through 11 as committee reports for december 7 with recommendations. supervisor campos: thank you very much. i believe this is the last meeting of the calendar year for the rules committee. again, i want to take this opportunity to thank all of the members of the committee, supervisor mar, supervisor alioto-pier, to once again thank the clerk linda wong for the tremendous work that she does, to the city attorney's office, to mr. chen and also to

the staff of sfgtv who have been covering the meeting for the last, the entire year and to all of you who have been watching, happy holidays. madam clerk, is there any other business before the committee? >> no, mr. chair. supervisor campos: great, thank you very much. meeting adjourned.

>> i have 2 job titles. i'm manager of the tour program as well as i am the historyian of city hall. this building is multifaceted to say the very least it's a municipal building that operates the city and county of san francisco. this building was a dream that became a reality of a man by the name of james junior elected mayor of san francisco in 1912. he didn't have a city hall because it was destroyed in the earth wake of 1906. construction began in april of

1913. in december 1915, the building was complete. it opened it's doors in january 1916. >> it's a wonderful experience to come to a building built like this. the building is built as a palace. not for a king or queen. it's built for all people. this building is beautiful art. those are architecture at the time when city hall was built, san francisco had an enormous french population. therefore building a palace in the art tradition is not unusual. >> jimmie was an incredible individual he knew that san

francisco had to regain it's place in the world. he decided to have the tallest dome built in the united states. it's now stands 307 feet 6 inches from the ground 40 feet taller than the united states capital. >> you could spend days going around the building and finding something new. the embellishment, the carvings, it represents commerce, navigation, all of the things that san francisco is famous for. >> the wood you see in the board of supervisor's chambers is oak and all hand carved on

site. interesting thing about the oak is there isn't anymore in the entire world. the floors in china was cleard and never replanted. if you look up at the seceiling you would believe that's hand kof carved out of wood and it is a cast plaster sealing and the only spanish design in an arts building. there are no records about how many people worked on this building. the workman who worked on this building did not all speak the same language. and what happened was the person working next to the other person respected a skill a skill that was so wonderful that we have

this masterpiece to show the world today. because we have a great waste water system here in san francisco, we do about 80 million gallons of waste water here in san francisco, which means we basically fill up 120 olympic sized swimming pools each and every day here in the city. we protect public health and safety and environment because we are discharging into the bay and into the ocean. this is essentially the first treatment here at our waste water treatment facility. what we do is slow down the

water so that things either settle to the bottom or float to the top. you see we have a nice selection of things floating around there, things from bubble gum wrappers, toilet paper, whatever you dump down the toilet, whatever gets into our storm drains, that's what gets into our waste water treatment and we have to clean. >> see these chains here, this keeps scum from building up. >> on this end in the liquid end basically we're just trying to produce a good water product that doesn't negatively impact the receiving water so that we have recreation and no bad impact on fish and aquatic life. solids is what's happening. . >> by sludge, what exactly do you mean? is that the actual technical

term? . >> it's a technical term and it's used in a lot of different ways, but this is organic sewage sludge. basically what it is is, oh, maybe things that come out of your garbage disposal, things that are fecal in nature. it's sludge left in the water after the primary treatment, then we blend those two over and send them over to digestion. this building is built to replace tanks here that were so odoriferous they would curl your hair. we built this as an interim process. >> is there a coagulant introduced somewhere in the middle of this? . >> this coagulant brings solids together and lets the water run

through. that gives us more time in the digestion process, more time to reduce the amount of solids. these are the biggest ones in the world, like we always like to do in san francisco. they are 4 meter, there's none like it in the world. >> really? wow. >> three meters, usually. we got the biggest, if not the best. so here we are. look at that baby hum. river of sludge. >> one of the things is we use bacteria that's common in our own guts to create this reduction. it's like an extra digestion. one of the things we have to do to facilitate that is heat that sludge up and keep it at the temperature our body likes, 98.6 degrees. >> so what we have here is the heat exchanger for digester no. 6. these clog up with debris and we're coming in to -- next wet

weather season so we always come through here, clean them out, make sure that we get maximum heat exchange during the colder wet weather. sludge season. >> rubber glove. >> right here. >> rubber glove, excellent. all right, guys. >> thank you. >> good luck. >> this is the full on hazmat. . >> residual liquid. we're taking it time to let it drain. we don't want to get sludge on it necessarily. take your time. stand on the side of it. . >> should we let it release for a while? . >> let it release. >> is that the technical term? . >> this is the most important

bolt on the whole thing. this is the locking bolt. it locks this thing right in place. so now. >> take your hammer and what we want to do, we get rag build up right in here. the hot water recirculates right in here, the sludge recirculates in here. the sludge sometimes has rags in it. all we want to do is go around the clean the rags. let me show you how. take the slide hammer, go all the way through the back, go around. >> got you. >> during the real rainy season, how does that change the way dealing with this job? is it a lot more stuff in there? . >> what we do, charles, we do this quarterly. every four months we go around and clean all the heat

exchangers so we don't have a large build up. . >> go around? . >> yeah. (sound of hammering). >> what i'm trying to do, charles, is always pull it out on the low stroke. >> right. so you are not, like, flying out. now talk about clean up. . >> then where does this stuff get deposited? . >> we're going to dump it in a debris box and it will go back to the plant.

>> if you think back, the romans came up with a system of plumbing that allowed us it use water to transport waste away from the hub of civilization, which enabled cities to grow. . >> you have a large bowl, a drive motor and another motor with a planetary gearbox with differential pressure inside there. the large mass up there spinning separating the solids from the liquid. we have to prevent about once a month, we go in there grease those, change the oil, check the vibration levels. the operators can tell just by the hum of that machine that it's a harmonic noise emitted that it's out of balance and the machine needs to be cleaned. it will start vibrating and we

have vibration analysis machines that will come over here and check the levels. so it's kind of an on-going thing that you have to stay on top of on a daily basis. >> handled properly, you take organic residuals, as we call them, that are leftovers of our society and turn them back into some energy. and we have another ability to take that sludge and get a nutrient value for crops there. we actually are running a kind of composting energy recovery system. >> well, this is a dirty job. we try to do it safely and we try to do it without imposing too much on the public. people want to flush their toilets and have things go away and not be bothersome again. we do a lot to try to accomplish that. i'd like to invite you to come back any time you want.

once you got this in your blood, you are not going to be able to stay away. the raging waters are fun and when we do digester cleaning i really hope you can come back. that's quite a sight. >> yeah, that sounds interesting. >> i really appreciate you coming by and it was a >> welcome to culturewater. in 2001, the san francisco arts commission and tampa does go public library established an arts master plan for the city soon to be renovated branch library. almost 10 years later, the san francisco arts commission has integrated a collection of vibrant new artworks by bay area artists into five new libraries, and there is more on the way. here is a closer look at some of the projects.
