other /pwraeugs to resist the lateral forces that might be imposed by the earthquake. so we're looking for something that is particularly weak or soft in this ground story. now, this is a wonderful example of what some of the residential buildings that are soft stories in san francisco look like. and the 1 thing that i would point out here is that the upper force of this building have residential units. they have not only a fair amount of wall around the exterior of the building but they also have very extensive walls in the interior and bathrooms and bedrooms and corridors and everything that has a certificate amount of brazing yea it's significantly less country /srabl in those stories. now very often, we get even a garage or storage or sometimes commercial occupancy in this ground story. that very often not

only has a whole lot less perimeter wall but it often has little or no wall on the interior. that wall is the earthquake bracing and so he see very significant bracing in the top floor and very little on the bottom. when the earthquake comes and hits, it tries to push that ground floor over and there's very little that keeps it from moving and degrading and eventually /paoerblly keeping it from a collapse occurring. so we know they're vulnerable because of this ground story collapsing >> is this only a problem we see in sentence france? san francisco? >> no, this is certainly a national problem. more acute in western but more up to california, washington, moving out into other states. this kind of building exist and this kind of building is vulnerable.

>> when you're involved with the community safety, this is a different way of thinking about these types of things. we had a community group of over 100 people involved and upper 1 of them. tell us about * how that conversation went. why did we decide as a city or a community to start fixing these types of buildings? >> there were a lot of aspects that were considered well beyond just the engineering answer that these are vulnerable. and that effort brought in a lot of people from different aspects of the community that looked at the importance of these buildings to the housing stock and the possible ramifications of losing this /houbgs in the case of an earthquake. the financial implications, the historic preserve vacation s implication as you mentioned, these are very handsome looking buildings that are importance to the tourist city ask which make san francisco something that people

are interested from outside in coming and visiting. >> it's such animation story when you think about the 10 years that the community spent talking about this /seurb but we actually did something about it. now we have an order unanimouses put in place to protect 100,000 residents in san francisco and retrospective in 2020. so on behalf of residents and employees in san francisco, we want to say thank you for the work you've done in pushing this forward and making people more aware of these issues. >> and it was a fantastic community effort. >> so in an earth quake, what happens in these kinds of buildings? >> what happens when an earthquake comes along is it moves the ground both horizontally and vertically. it's mostly the horizontal that we're worried about. it starts moving the building back and forth and pushing on it. when you see i'm pushing

on it, the upper stiff of the wall stay straight up but the lower floors, they actually collapse just like i did there. >> luckily, we can put this building right back up where it came from so it's a lot easier. now kelly, obviously these aren't real frame walls here but when you talk about buildings, what makes the property for stiff? >> the easiest and most cost-effective type of bracing you can put in is either put in a brand new wall or to potentially go in and strengthen a wall that's already there where you don't need to have an opening is where you maybe have a garage door or access to commercial space, you might go to a steel frame or other types of bracing systems that provides the strength and stiff if necessary but at the same time, allows continued use of that area. but some combination of walls or frames or other tools

that are in the tool kit that can bring the building up to the strength that's required in order to remove the vulnerability from the building so that when ground shaking comes, it in fact is a whole lot more resistant and less vulnerable. ideally, this story down here would be made as strong and stiff as the floors above. >> if i'm a property owner, what is the first thing i should do? >> the first thing you should do is find professional that can come in and help you evaluate your building in order to, 1, figure out that indeed it does need to be retro fitted and 2, give you some idea of what that retro fit might look like. and third, evaluation and design to help you determine the retro fit requirement. >> well kelly, i can't thank you enough for being here today. thank you so much for your wealth of

information on how we can take care of our soft story problem in san francisco. and you the viewer, if you have any questions, please feel free to visit our website -

>> welcome to the epic center did you know you may be eligible for a 3 thousand redefeat beating he'll learn about the stay safe program hi, everybody i'm patrick chief resigns director for the city and county of san francisco welcome to another episode of stay safe i'm here with jennelle for the california earthquake authority she'll talk about brace and bolt good to see you. >> earthquake brace and bolt the first incentive program of california mitigation program as jointly managed by the earthquake authority and the california gvrnz of department

of emergency services. >> and what is the mission. >> brace and bolt is $3,000 up to a homeowner that retrofits the equivalent in a single-family. >> we're down owe epic center the public demonstrates we've built a mock house so i don't in the take a look at it and and show you what we're talking about we're in a model house in the epic center to demonstrate a variety of things jen i will i want to focus on the portion of the house and tell us how brace and bolts help to keep the home safe. >> this is a particular foundation and that mockup shows the first floor right here and, of course, this one is the concrete foundation and this short wall that is in between those two you're first floor and the concrete foundation is called a cripple it is a short

wall this is a particular vunltd in 0r8d homes they're designed before metamorphic coddling codes and will slide off the foundation. >> if you come to my home look at the previous work. >> so see if any anchor bolts between the wood and this mud and concrete foundation that is a collar bolt. >> what if i don't have enough space power a think collar bolt and we have foundation plates made by a company where a flat plate that is bolted to the concrete foundation and screwed into this flat mechanism. >> if i applied to a bolt what is a it coffer what type of work should you do in my hope. >> up to $3,000 funding with

the collar bolts or foundation plates and plywood up to the top of the short triple wall that going around. >> what are the tips. >> you want to make sure the capital improvement plan emancipation proclamation he will the short wall is less than 4 feet tall you'll use the provision to adopt it to the city of san francisco so a contractor can use that. >> so if i have a typical house over a garage and did that quality for the program. >> that would qualify for the program you need an engineer to design the riefrt it is not specific for that kind of house it is really they're looking for short cripple walls maybe a couple of steps up. >> so jen i will if i want to find out more information.

>> earthquake brace >> good morning. good morning, everyone. i'm timothy fu, chair of the board of trustees for the san francisco skefconservatory of m. on behalf of the board, thank you all to be here for the breaking ground on the ute and william k. duboce center for being pyrri performing arts. when i joined the board many

years ago, we knew the conservatory belonged with the many arts at the civic center, and we knew we must providing housing for our students. so we succeeded in moving to the civic center in 2006, and now, we're breaking ground for the new student residence hall. so today, i'm incredibly proud of how all of us have come together to make the future possible. and i want to express my deepest thanks to the supporters of this project whose inspiring leadership and generosity have set us up for a successful second century of leading music education through innovation through a history of excellence, achievement, culture and collaboration. now i have the pleasure and the

honor to introduce our mayor, the mayor of san francisco, london breed. [applause] >> the hon. london breed: thank you, everyone. what a beautiful day to break ground on hundreds of units of housing for student artists. one the things i love to do as mayor. some of you know i used to serve as director of an organization, the african american arts and culture complex. it's not far from here, but we had incredible relationships with the arts community here where you have the symphony, the opera, sf jazz. this place has become a hub for artists everywhere, and now that the san francisco conservatory of music has decided to take it even a step further to decide to

come up with this innovative plan to come up with 420 units of housing for their students, it's absolutely amazing, and we should all be proud of what this project would do for housing in the city and county of san francisco. [applause] >> the hon. london breed: thank you also equally important, the 27 residents who were once housed here were not only housed very close to this particular development as it's under construction at the same rent they were paying, they will also be moved back into this building when it's built at the same rents that they had been paying through their rent control. and here's the thing: 27 people are not being displaced as a result of this project. we are adding more units, we're not displacing anyone, and the reason this is so great for the environment, it is within

walking distance of the san francisco conservatory of music. [applause] >> the hon. london breed: i can't be more proud. we have to do more to build more housing in san francisco. we have to think about the fact that this is an innovative place. people want to live here, they want to work here, they want to grow here, they want to thrive here, but what makes san francisco incredibly -- a great place for all of us, it's the arts, it's the music, it's the entertainment. it's all of the things that people come here to enjoy, and how are we going to continue to grow if we don't have opportunities that exist for them? if we don't provide housing that they can afford? if we don't open the doors of our opportunities to our artists who we know are constantly being displaced? it's a great day for san francisco, it's a great day for the arts community, and i am so

looking forward to all the work we're going to continue to do to revitalize the civic center area. yesterday, i looked out the window from my offices at city hall, i saw children playing in the park, i saw people standing in line at the birite we just opened two days ago, i saw people doing zumba, i saw people talking to people on the street, just hanging out. it's amazing, when you're taking care of everyone, including the community, every can enjoy. this is a project that's going to benefit this area and hopefully grow and thrive and provide places like this that provide housing like this for each and every one of us. thank you all so much for being here today. [applause] >> thank you, mayor. thank you so much for your

support and your commitment to the arts. we really are very honored to have you take time from your busy schedule today to be with us. and now, i have the pleasure of introducing the person who has designed this building, marvelous facility for all of us, but the best design architect in the city of san francisco, mark cavanero. >> thank you. we've been working on this for years, to see a building coming out of the ground is every architect's dream. we talked about innovatition as we talked about this project, andhi
