before. >> you expect to see them during the apocrine fall. in fact, they might occur at that time but they may occur the year after and two years after because it has taken awhile for it to accumulate. this triggered some major landslides that we saw. these are portions of the cliff rotates out to sea. >> when we look at this cliff, can you tell us what of the features that we can see? >> we are lucky to have a very fresh exposure. there is a large overhanging block. at the very edge, you can see the roots coming out. they are part of the problem.

in addition, these are sandstone and shale. they have been uplifted and faulted and put into the position they are in today. on the cliff face, you can see the bedding of the shale. there are vertical cracks that filled the water and plans is growing. -- and plants are growing. the cumulative effect of the fresh cut with the debris sitting on the ledge, luckily we have a chance there to protect us from rocks going on the street. >> this is one type of rock salt and we will look at a few others. what will we see? >> i think it would be appropriate. we have been talking about rock salt.

there is instability that occurs at telegraph hill. this was more in the earth flow and debris flow kind of movement. this moves downhill as a result of the rations from the earthquake. that is where we are headed next. >> here we are on the next stop of our landslide for parent though this is the lagoon ouna a area. this is different from where we all were just add on telegraph hill. this is a whole different concept. tell us what we have to. we have the big hill behind us,

what kind of formations do we have? >> this part of san francisco, we are out in the dune sands which makes up the hill to my right. a crusty old drainage that we are standing is bedrock, 160 million year-old sandstone. the project right in the hillside over there and then farther down along the path that goes to the reservoir. >> there are rock slides, there is unconsolidated material. we have an earth float type slide and a debris flows which are common on the these hillsides where you start to see the evidence of creaks when the trees start to lean over.

>> this is a slow movement of the slope. >> yes. you can start to get moving. that will push the trees over a little bit. this had a special history. we had a lot of damage here. i guess the water from leaking laguna runs underground out to golden gate park. it covers about two or three blocks along side to seventh avenue. there was a lot of water damage we might have even had some liquefaction soil failure. we had a major failure. >> that's right. this tribute goes all the way to golden gate. this is in a mountain lake and

beyond ththat, it was a surface flow. this is a reservoir. on my right is this defensive the positive dune sand. the wind blows, it comes from the ocean beach. because the sand is moving, you can see evidence along this side of the hill in 1989. the vibrations in accelerated. you have a significant amount of movement to the point that the homes that uc had very severe damage for two blocks. we recognized what the problem was at the time, it was a matter of loose sand on a very steep slope. thank you for the effort. we were able to get federal funding and design which you see in the upper walls.

the lower walls was actually billed as part of the wpa. the upper wall was built in 1991-'92. this is a concrete wall and it has rocked going through the wall that extends the distance of 80 feet beyond the wall. the next earthquake occurs, the wall is designed to resist and the movement of the sand and allowed it to move down hill. this is a classic example of the creek and degree flow and exists all the way the area. we might see the other evidence. we have done nothing to improve the quality and the strength of the dam. >> one of the things that has come up in the policy issue over and over is that people are concerned that construction of a new building or the upper story

might exacerbate these kinds of soil problems. we have extra review where we might have extra problems. it does that construction have an impact? it is a good idea to come to a peer review or a geotechnical review process as part of determining. >> in january of this year, the california building code requires almost all of san francisco that we get geologist and a geotechnical engineer. it was a state building code rather than just the local requirements. >> as you recall, this was called the edge hill ordinance.

>> is this the same kind of condition? >> this is more of the rock, all on one side and on the other side -- >> this is a combination. >> a lot of sand hills were scrapes down and deposited to other places without being engineered or consolidated and people build on top of that. we have a whole change as the city surfaced. what is the deal with sand, is this a good place to build on? >> if you want to understand the

properties and if you designed to mitigate any adverse effects of the settlement, this is the strongest. i live in the sunset, i have been doing this right on the other side of this hill. i see the same conditions exist here where we have the earthquakes and the sand shakes and it gets more dense. we see differential settlement of are on. >> they might have filled in a low land or a wet land and build on top of it. this is a fully grated sand. seeing difficult to distinguish what was natural. you could be growing like we do and as difficult to distinguish the context between this and the

natural sand. we have to go by its consistency. >> in san francisco, we have a tremendous resource. we have a collection of soyoil supported that goes back many decades and they cover the whole realm of the city. we have them at the apartment building inspections. someone understands what they are. you can look at them and read them and find one in your neighborhood. is that right? >> that is true. many geologists have spent many years mapping the geologic conditions. there are excellent maps of the city. in fact, there are a hazard maps. in 1974, there was a landslide map. >> that's right. that is available at that

apartment building inspection. these are excellent maps. >> there is a real legacy of geologists working and now cannot always published. san francisco has a great repository of some of these archives. there is a child just -- a geologist to publish letters that is a great source of information. we are on the coast, they have the definitive work for all of the [inaudible] >> and did they pick up the old [inaudible] and wetlands? >> there was a map of those that

weren' off the field. you can see where these are with respect to those that have been filled in with a debris from the 06 earthquake. >> that is one of the things i've learned, the very local zones, exactly where you are building at. side-by-side, san francisco is so varied in its tomography and geology, you cannot tell by looking at the site specifically. >> this will be at the end of the drive. you can show which time we will be looking at out there.

>> these are called rotational. >> there can be a lot of movement all at once. they can slowly creep for long amounts of time. >> here we are at the top of an escarpment that pretty much the end of the world. it is windy and cold. just south of here is some also rock where the san andreas fault goes into the pacific ocean. this is closest to the san andreas fault. many people believe that the closer you are to default, the greater the ground motion might

be. that is a portion that is a south westerly portion of san francisco that has some special earthquake hazards. we are here to talk about the geology of this area. why don't you tell us about what is going on? >> there is a giant step here at the edge of the escarpment, the edge of the landslide. all the land to the west of us is part of a landslide that is upwards of 200 feet deep. it goes underneath the ocean. it causes damage and it was mapped by the earliest geologists'. there are many kinds of rocks here. there is a big sequence of merced formation. this is a base in deposit that was formed by the interaction at

the end of the continental margin. >> this is just on top. this is the same material that we were looking at at the last site. you can see it is on our way to the last side. it is deposited here by wind. it is 40-50 feet thick. this acts as a big sponge. the water flows through and it gets in a lower formation and then the water level starts to rise and it becomes a reservoir for water. this is dissipated during the more dry months of the year.

>> this forms a big long skinny basin and runs into san francisco. it is the coastal bluffs areas that are subject to erosion from the waves and the ground water that comes out and you start to lose this. this is the largest example of failure for a long part of the coast. it has been moving continuously for a long time. >> the ocean was at the same level as we are standing. in 1982, and massive slide occurred further to the north of and one day it moves 5 feet and by the second day it moves 30 feet out. all of that land down below was sitting out here. it was a great deal logic

feature of the landslide further to the south. there were houses on top and there was a very steep slope. you can see some debris slides where the sand is slowing. then you drop into a gully or a drainage swell. the top of the landslides' is just a drop in the middle where another clock has pulled away from the edge. the higher hill on the outside edge of the rich and the depression is the drop. surface erosion is an acute issue. >> you can see the evidence of the houses directly adjacent. we have similar conditions to that. if you go around the corner around the seacliff, where in fact there has been significant

movement and in fact many of the homeowners along that portion of the seacliff have had to come back in and do extensive foundation repair and massive walls to protect the home while the slope [inaudible] >> here we have the shallow slides, a debris slides. during earthquakes, they are both activated and the movement on the deep sea slides accelerates as well as the official material that erodes. >> if there's one point that is brought home from this discussion of landslides is san francisco is a part of the community that experiences many

types of landslides, rockfalls, deportations. we need to be aware of the geologic and topographic setting we are in. when we are planning to build our home or buy a home or at additions to the home. if i have one suggestion, that is to seek information from the apartment building inspection. if you're not satisfied, there is ample information there. a geologist needs an opinion of the stability of the environment you're in. >> the building department will typically require that kind of information. people will do a major edition. what we are wondering is why we require that information. >> great, thank you very much. it is terrific.

it is fun to see a lot of the city. thank you. announcer: this is sarah watkins. a lot of people almost helped her. one almost cooked for her. another almost drove her to the doctor. still another almost stopped by to say hello. they almost helped.

the almost gave of themselves. but almost giving is the same as not giving at all. you are so lost. no, i'not, man. dude! i dropped my phone. oh, the road! whoa. yeah. you know what i'm saying. how would you like to save your life from an ugly reckless driving death? don't answer yet, there's more! act now by slowing down and we'll guarantee you complete satisfaction! kids: that's awesome! announcer: in the real world... passenger: whoa, andy, slow down! >> ladies and gentlemen, good morning.

welcome to the fresh and easy third capital opening. thank you for being here. there are some fantastic displays of green clothing in this building. i have seen the most wonderful pair of green shoes. melissa has got green hearings, fingernails, everything, to show the green spirit of fresh and easy. well done, melissa. magnificent. [applause] the reason that we all like to wear green, the reason we are so proud of green, is because we like to be the change we want to be. mayor lee, thank you so much for coming.

we are delighted that you are here. i am going to introduce most of our distinguished guests. a number of them are going to say a few words to you in a bit. i would like to welcome the city attorney dennis hora. i want to welcome herb schultze, and the region 9 director of health and human services. i would like to welcome former supervisors over the maxwell. she and i did the original brown working together. she says she remembers something a lot about me, but does not remember what it was, which is probably good. i want to welcome the chair of the bayview project committee. [applause] i think we were a bit slow off the mark, so let us please have

a round of applause for the mayor, city attorney. [applause] i never thought i would have to do this -- where is he? how i would like to welcome alexander, our broker. i would like to welcome the president of the board, david chiu. [applause] i would like to welcome malia cohen, -- sorry, she is not here, but her staff is here. she has been a great supporter. i would like to welcome emily, a school board member. [applause] i would like to welcome rev. townsend and were really is whopper. i would also like to welcome

michael for his assistance. anyhow, what i would really like to do -- it had been an awful long time since we agreed to do this project. i want to thank the mayor's office for their consistency and steadfastness. and i also want to thank, in particular, amy cohen and roberto munoz for their contribution. [applause] amy said that roberta did not have a gray hair when we started the project. [laughter] i am delighted that we are doing this project, an amazing event. it is an absolute privilege to be able to do these sorts of things with people who are happy, feel they are making a difference. supervisor maxwell was so positive and charming when we started out.

i am delighted that we made it. >> [inaudible] [laughter] >> that is certainly true. for every store we open, we make a $1,000 donation. the donation we are making today will go to bayview hunters point ymca. i met some of those people today. [applause] we have opened 177 stores since we started in november 2007, and we have invested over $2 billion, and we have created over 4500 jobs, mainly in california, particularly in our production facilities in riverside, but also in arizona. we have worked hard to create a thoughtful business that can make a difference to communities, a business that is

both economic and social sense. we have set out to create a modern 21st century business, a business that is great to work in, and great to shop in. one of the things that people said to us when we did our original research is food today is too messed around with. do not put stuff in that i cannot read, that i cannot announce, ingredients that i cannot pronounce. have a look at the ingredient labels, if you have a moment. our mashed potatoes as potatoes, cream, salt, pepper. nearly every other mashed potato that you have eaten has something else in it that you have not heard of. so have a look around and enjoy. the food even tastes cleaner. when you eat fresh and easy food

-- you get that feeling -- what is missing? what is missing is all of the additive that coat your mouth. i promise there is a difference. every week we sell 98 said produce, $1.99 chicken breasts. we have the key, fresh food basics that you need to run a family for everyday cooking here in the store, the prices are good. you can see in the back where we make sushi, pizza, soup, entrees. you name it -- we even make sliders. they are fantastic. it is all just so good. i just want to roll around in it and enjoy it. even a microwaves. if you live nearby, you do not

have to get fast food, you can get real food and put it in the microwave. no artificial colors, no artificial flavors, trans fat, no high fructose corn syrup. we took them away. [applause] as i said early on, we have tried to make this a great place to work. trust me, wherever you go, the parking lot of the grocery store, the garden center, what ever it is, if you get that service, it is because the boss designed a bad business and the staff cannot do what they were intended to do. what i have tried to do with these people is to design a business where service can be delivered day in and day out without stressing the living hell out of them.
