giants. >> you guys want to know why this is important? because it gives us the chance to work with the police department and the fire department. and it gives us the opportunity to be the leaders and as a whole we can really make a difference. >> by sometimes young people get on unfair wrap for not caring about the world around us. we do but sometimes, we don't know how to show it or what to do >> and i want to make a really, really good point san francisco lincoln school is the only school that supports picking up trash and the giant with sweep.

we'll never forgot his talks. show your love right now and give it up for giants right fielder. hunter. >> yeah. hello lincoln high school. how's it going out there. how do you feel about san francisco giant chamber? pretty amazing. we definitely wouldn't have done it without the help of everyone in san francisco. there were so many people who

were involved just besides us and i think if you look back at what really went on in the playoffs we made a decision when we were detain 2 games from the cincinnati reds. we had an easy decision to make. it would have been pretty easy to give up. i remember we heard on the radio that there was no way the 70 giepts were going to win. well, we decided to make a decision we weren't going to play four ourselves we were going to play for each other. we didn't care if with had to

win a hundred games we were going to win that day. it's the same challenge we ask i. there's a decision everyday between what's right. and what's easy. it's easy to look away but i've been in a lot of cities and san francisco is one of the most beautiful places i've ever been in my life. i absolutely love it here he every time i go to the park i'm so happy. you can't compare it to anywhere. you guys are spoiled. it's beautiful. by at the end of the day let's keep san francisco beautiful and clean. and let's do this ever day and

let's get this win >> come on we can do better than the that. the second-graders from the day school have been working on this chant. are you ready to do this. i going to say this with me. join the team, keep s f clean. i say it join the team, keep s f clean. join the team, keep s f clean.

give it up for all the kids. good job. thank you everybody. let's go giants. let's go mustangs have a great game. good afternoon. thank you >> the public wants to access particular information about your house or neighborhood we point them to gis. gis is a combination of maps and

data. not a graphic you see on a screen. you get the traffic for the streets the number of crimes for a police district in a period of time. if the idea of combining the different layerce of information and stacking them on top of each other to present to the public. >> other types of gis are web based mapping systems. like google earth, yahoo maps. microsoft. those are examples of on line mapping systems that can be used to find businesses or get driving directions or check on traffic conditions. all digital maps. >> gis is used in the city of san francisco to better support what departments do. >> you imagine all the various elements of a city including parcels and the critical

infrastructure where the storm drains are. the city access like the traffic lights and fire hydrants. anything you is represent in a geo graphic space with be stored for retrieval and analysis. >> the department of public works they maintain what goes on in the right-of-way, looking to dig up the streets to put in a pipe. with the permit. with mapping you click on the map, click on the street and up will come up the nchgz that will help them make a decision. currently available is sf parcel the assessor's application. you can go to the assessor's website and bring up a map of

san francisco you can search by address and get information about any place in san francisco. you can search by address and find incidents of crime in san francisco in the last 90 days. we have [inaudible] which allows you to click on a map and get nchldz like your supervisor or who your supervisor is. the nearest public facility. and through the sf applications we support from the mayor's office of neighborhood services. you can drill down in the neighborhood and get where the newest hospital or police or fire station. >> we are positive about gis not only people access it in the office but from home because we

use the internet. what we used to do was carry the large maps and it took a long time to find the information. >> it saves the city time and money. you are not taking up the time of a particular employee at the assessor's office. you might be doing things more efficient. >> they have it ready to go and say, this is what i want. >> they are finding the same things happening on the phone where people call in and ask, how do i find this information? we say, go to this website and they go and get the information easily. >> a picture tells a thousand stories. some say a map >> in this fabulously beautiful

persidio national park and near golden gate and running like a scar is this ugly highway. that was built in 1936 at the same time as the bridge and at that time the presidio was an army and they didn't want civilians on their turf. and the road was built high. >> we need access and you have a 70 year-old facility that's inadequate for today's transportation needs. and in addition to that, you have the problem that it wasn't for site extenders. >> the rating for the high

viaduct is a higher rating than that collapsed. and it was sapped quite a while before used and it was rusty before installed. >> a state highway through a federal national park connecting an independently managed bridge to city streets. this is a prescription for complication. >> it became clear unless there was one catalyst organization that took it on as a challenge, it wouldn't happen and we did that and for people to advocate. and the project has a structural rating of 2 out of 100. >> you can see the rusting reinforcing in the concrete when you look at the edges now.

the deck has steel reinforcing that's corroded and lost 2/3's of its strength. >> this was accelerated in 1989 when the earthquake hit and cal came in and strengthened but can't bring to standards. to fix this road will cost more than to replace. and for the last 18 years, we have been working on a design to replace the road way, but to do in a way that makes it appropriate to be in a national park and not army post. >> i would say it's one of the most ugly structure, and it's a barrier between the mar sh and

presidio. and this is a place and i brought my dogs and grandchildren and had a picnic lunch and it was memorable to use them when we come here. what would it look like when the design and development is completed. and we are not sure we want an eight lane highway going through this town. and it's a beautiful area in a national seaport area on the planet. >> the road is going to be so different. it's really a park way, and it's a parkway through the national park. and they make the road disapeer

to the national park. >> and the road is about 20 feet lower, normally midday, you go through it in two minutes. looking back from the golden gate bridge to presidio, you are more aware of the park land and less of the roads. and the viaduct will parallel the existing one and to the south and can be built while the existing one remains in operation. and the two bridges there with open space between them and your views constantly change and not aware of the traffic in the opposite direction and notice the views more. and the lanes of course are a foot wider than they are today. and they will be shoulders and if your car is disabled, you can pull off to the edge. and the next area, the tunnel

portal will have a view centered on the palace of fine arts and as you come out, you can see alkatrez island and bay. and the next area is about 1,000 feet long. and when you come into one, you can see through the other end. it's almost like driving through a building than through a tunnel. and noise from the roadway will be sheltered. and the traffic will be out of view. >> when you come out of the last sort tunnel and as you look forward, you see the golden dome of the palace of fine arts and what more perfect way to come to san francisco through that gateway. >> it will be an amazing

transformation. now you read it as one section, the road is a major barrier and then a wonderful strip along the water. all of those things are going to mesh together. >> right now the road really cuts off this area from public access. and with the new road, we will be able to open up the opportunity in a new way. >> this bunker that we see now is out of access for the general public. we are excited to completely rework this side and to open up the magnificent views. and what we want to do is add to this wonderful amenity and restore this coastal bluff area and respect its military

history and the doyle drive project is allowing us to do that recorrection. and this area is not splintered off. >> and we can see how dramatic a change it will be when doyle drive is suppressd and you have a cover that connects the cemetery to this project. it's historic on the statewide and national basis, but you could rush the project or put thought and time to create something of lasting public benefit. >> we really want this, for everyone to feel like it's a win situation. whether you are a neighbor that lives nearby or a commuter or user of the park. that everyone will experience a much better situation than they currently have.

>> the human interest to me is how people could work out so many challenging differences to come to a design that we believe will give us a jewel. landmark of a place. >> i am sure it will have refining effect like embark did. and there were people about that and no one would think of that today. and when you look at growth and transformation of the embark, the same with doyle. it will be a cherished part of the city and a worthy addition to what is there. >> it will be a safe and beautiful entrance to a spectacular beautiful city. it will be the entry to golden gate that san francisco deserves.

across america, cities and towns, homes and businesses all depend upon one basic resource. modern civilization and life itself would be impossible without it. woman: okay, so today, we're going to look at how do we get our water? narrator: and today, it's a matter of simply turning on the tap. so often, we forget about the value of water. water is a commodity that is essential to life. 100 years ago, it would have been hard to imagine turning on the tap water. and now, it's an expectation.

narrator: over 300 million people live in the united states. and each person uses an average of 100 gallons of water every day. man: what it takes to actually make clean water is somewhat a mystery to most customers. woman: so how does water get from the river into your house, or here at school? woman: somebody has to bring that water to us, and somebody has to take it away when we're finished with it. man: the water infrastructure is vital for disease protection, fire protection, basic sanitation, economic development, and for our quality of life. man: you just can't visualize all the assets that are under our feet. we have about two million miles of pipe in this nation. if you're walking around in an urban area, you're probably stepping on a pipe. man: our grandparents paid for, and put in for the first time, these large distribution systems.
