I am the chief building inspector. We are here at the base of Telegraph Hill to talk about a subject of great interest for the people of San Francisco which is rockslide, slope stability, which caused a dramatic frontpage news. I am here with two knowledgeable and wonderful guests. I am here with a geotechnical engineer and a geologist. We are here to talk about rockslide, rockfalls, and related issues. What is the difference between a geologist and a geotechnical engineer . And engineering geologist deals with identifying site characteristics, mapping, the grounds surface, collecting all of this data. The engineer can come up with medications and designs. The Structural Engineer might be working on a building if there is a building involved. What is your role .

Makes a big difference the texture of the salt, not word is from where it is from. Where is this from . It is from france, the top layer of of salt, a very fine salt. For every 80 pounds of the great salt, 1 pound of this is made. We did not really talk about the clock tower yet. At 230 feet tall, this is built as a replica of of the clock tower in spain. This was electrically i polite. Electrically operated . Correct, but it still can be run mechanically. Ithe clock master comes in at te time that it is changing. We also have clock watchers across the street who tell us if it is off by a second, so he is very attached to the clock. We have a clock master. And look at this, the hands of the clock. Look how big they are. The holy mackerel. Nobody is up here. But this. It the great seal of the state of california. This is a wonderful mosaic. It is wonderful. It was original to the building. Tens of thousands of people cross by every day. This is the waiting area. The larger alcoves or fo
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, lets 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 d
