Thank you for having me. [applause] thank you so much. God bless you all, ladies. I love you. [applause] it starts with us. We have to be together, no matter what. Thank you so much. God bless you, take care. [applause] all right. Give it up for ledeci. Give it up for ledeci one last time. She can hear you back stage. [applause] there you go. The mayor told me that she would pack into a crowded cafe and listen to ledeci years ago, so here she is back on the mayors stage. So i got a promise from the mayor back stage that she wants to see you back he volunteers. My name is mark a proud grand date i didnt all over San Francisco residents are adopt rains to keep our sewer system healthy im adopted a grain draining i thought of a simple illusion to a big problem it will help out the neighborhood and be responsible for the places we live i want or apparent to the web site and [ ] homelessness in San Francisco is considered the number 1 issue by most people who live here, and it doesnt just affect Neighbors Without a home, it affects all of us. Is real way to combat that is to Work Together. It will take city departments and nonprofit providers and volunteers and companies and Community Members all coming together. [ ] the product homeless connect Community Day of Service Began about 15 years ago, and we have had 73 of them. What we do is we host and expostyle event, and we were the very force organization to do this but it worked so well that 250 other cities across the globe host their own. Theres over 120 Service Providers at the event today, and they range anywhere from hygiene kits provided by the basics, 5 to prescription glasses and reading glasses, hearing tests, pet sitting, showers, medical services, flu shots, dental care, groceries, so many phenomenal Service Providers, and what makes it so unique is we ask that they provide that Service Today here it is an actual, tangible Service People can leave with it. I am with the hearing and Speech Center of northern california, and we provide a variety of Services Including audiology, counselling, outreach, education, today we actually just do screening to see if someone has hearing loss. To follow updates when they come into the Speech Center and we do a full diagnostic hearing test, and we start the process of taking an impression of their year, deciding on which hearing aid will work best for them. If they have a smart phone, we make sure we get a smart phone that can connect to it, so they can stream phone calls, or use it for any other services that they need. San francisco has phenomenal social services to support people at risk of becoming homeless, are already experience and homelessness, but it is confusing, and there is a lot of waste. Bringing everyone into the same space not only saves an average of 20 hours a week in navigating the system and waiting in line for different areas, it helps them talk, so if you need to sign up for medical, what you need identification, you dont have to go to sacramento or wait in line at a d. M. V. , you go across the hall to the d. M. V. To get your i. D. Today we will probably see around 30 people, and averaging about 20 of this people coming to cs for followup service. For a participant to qualify for services, all they need to do is come to the event. We have a lot of people who are at risk of homelessness but not yet experiencing it, that todays event can ensure they stay house. Many people coming to the event are here to receive one specific need such as signing up for medical or learning about d. M. V. Services, and then of course, most of the people who are tender people experiencing homelessness today. I am the representative for the volunteer central. We are the group that checks and all the volunteers that comment participate each day. On a typical day of service, we have anywhere between 40500 volunteers that we, back in, they get tshirts, nametags, maps, and all the information they need to have a successful event. Our participant escorts are a core part of our group, and they are the ones who help participants flow from the Different Service areas and help them find the Different Services that they needs. One of the ways we work closely with the department of homelessness and Supportive Housing is by working with Homeless Outreach teams. They come here, and these are the people that help you get into navigation centers, help you get into shortterm shelter, and talk about housing1st policies. We also work very closely with the department of Public Health to provide a lot of our services. We have all types of things that volunteers deal do on a day of service. We have folks that help give out lunches in the cafe, we have folks who help with the check in, getting people when they arrive, making sure that they find the services that they need to, we have folks who help in the check out process, to make sure they get their food bag, bag of groceries, together hygiene kit, and whatever they need to. Volunteers, i think of them as the secret sauce that just makes the whole process works smoothly. Participants are encouraged and welcomed to come with their pets. We do have a pet daycare, so if they want to have their pets stay in the daycare area while they navigate the event, they are welcome to do that, will we also understand some people are more comfortable having their pets with them. They can bring them into the event as well. We also typically offer veterinary services, and it can be a real detriment to coming into an event like this. We also have a bag check. You dont have to worry about your belongings getting lost, especially when that is all that you have with you. We get connected with people who knew they had hearing loss, but they didnt know they could get services to help them with their hearing loss picks and we are getting connected with each other to make sure they are getting supported. Our next event will be in march, we dont yet have a date set. We typically sap set it six weeks out. The way to volunteer is to follow our newsletter, follow us on social media, or just visit our website. We always announce it right away, and you can register very easily online. A lot of people see folks experience a homelessness in the city, and they dont know how they can help, and defence like this gives a whole bunch of people a lot of good opportunities to give back and be supported. [ ] good morning, everyone, thank you for coming to city hall. Being here today. My name is naomi kelly, the city administrator for the city and county of San Francisco. And i want to welcome you all to the Tall BuildingSafety Strategy summit. Im very pleased with the turnout this morning, so i really cant thank you enough for spending your morning with us today, this is very important what we are doing and talking about the resilience of our buildings in the downtown San Francisco neighborhood. As you know, there are much our skyline has changed and we see many more Tall Buildings there, and many of the Tall Buildings are not just Office Buildings but residential buildings and talking about the resilience of the city. Happy to be with you all here today. A great opportunity for city officials, staff, experts, stakeholders, to engage in recommendations set forth by the Tall BuildingSafety Strategy which was originally released last october. I want to thank tom, the director of building inspections. Tom is right here. [applause] mary ellen carroll, director of the department of Emergency Management is right here. [applause] im not sure, i dont see her in the crowd but may be, kathy howe, the assistant general manager of infrastructure for the San FranciscoPublic Utilities commission. But the four of us really started working on the resilience of our Tall Buildings well, a few years ago. A couple years ago, and have spent a lot of time with the applied Technology Council, office of resilience and Capital Planning, brian strong, and to really make sure that we think about these buildings in a different way than we have in the past. You all have a copy of the Tall BuildingSafety Strategy. Its the first of its kind in the nation. And it brings us together today. During the summit you will hear from many people who care deeply about making sure our Tall Buildings and infrastructure is strong. But we also want to focus on an open public discourse. We want to focus on engaging you on how we should prioritize the 16 recommendations that were in this strategy. And we need to think about the next big earthquake. I say this all the time in almost every public speech but i cant say it enough to remind us why we are here today that the u. S. Geological survey estimates San Francisco will have a 72 of an earthquake of a 6. 7 magnitude in the next 30 years. So, we need to think about this on a regular basis and keep this in the forefront of our minds. Thankfully we have a community of renouned experts to make sure the highly complex structures are well equipped and resilience for the safety of our residents, workers and visitors. Again, thank you all for joining us here today and now i would like to invite a member of the applied Technology Council, greg deerline, professor at stanford, and who has been our guiding expert on Structural Engineering to help us understand these Tall Buildings in San Francisco. Greg. Okay. Thank you, naomi, for the nice introduction. Yes, so its really a pleasure to be here today and report on behalf of the team and the applied Technology Council that put together the Tall Building strategy in a more detailed report Available Online and your folder. Many of the members on the team are with us here today and will be participating in the later Panel Discussions. Thinking about the plan itself, and really has history back in the work that San Francisco did, the Community Action plan for seismic safety initiated some years ago of pioneering effort, to bring together professional, emergency managers, working with the city and the communities in the city to think about the vulnerability and infrastructure and so on. So this Tall Building project follows on that, recognizing that some of the action plan is looking at the existing, and whether retrofits are required and recognizing that Tall Buildings and other special structures are unique, ways that you would inspect or think about a 3, 4story wood frame structure is different than a modern or older high rise building. One of the genesis and motivation for the project. One of the first things to get a handle on the Tall Buildings in the city. San francisco is proactive with s. F. Data, inventory of buildings, we added on to that, looking specifically at Tall Buildings and focussing above those 240 foot tall. Nothing magic about the 240 number, its a trigger in the Building Code for certain requirements, but any building of that size or close to it could be important to look at. So, this was partly, this inventory online, you know, categorizes some of the details, occupancy and so forth of the Tall Buildings. And so some of the things that we looked at there, for example, occupancies in the Tall Buildings, recognizing that about half the Tall Buildings, office occupancy, the other half are either residential or mixed use occupancy, and the balance is changing over time. Basically the Tall Buildings are primarily Steel Construction built in the 1960s through the 1980s, on the other hand, proliferation and Residential Construction is more reinforced concrete, often sheer wall system, so thinks about the occupancy of the building. Also think about the structural systems, important for earthquake engineers to advise on the expected performance of some of the older buildings, so understanding the buildings reinforced concrete or structural steel or the frame or the brace systems, and this required work of going into the San Francisco d. B. I. Looking at old drawings to pull out the information and bring it forth in the database. Now that we have the database, the landscape of the buildings and when they were built. This graphic is showing the 1960s up through the present, when different types of buildings were the constructed. Steel frames, and red are various types of buildings. And think about some events that have happened. 1971 san fernando earthquake, one that was a big, raised awareness of the hazard for concrete construction, nonductile concrete construction. Building codes changed subsequently, and buildings built before that were a concern. And many concrete buildings on the landscape, about 3,000 in San Francisco, built before that, genuine hazard, only a few of them are in the Tall Building inventory, but that does not minimize at all the hazard that the nonductile concrete has to people in city that in habit them. Another, the 1994 northridge earthquake. Vulnerability in the welded column connections due to a host of issues on detail, and toughness and so forth, raising performance of the Steel Buildings built before that time. And then the third thing that evolved is in the 2000s, modern performancebased engineering methods came on board, using advanced methods of analysis that allows earthquakes, structural and Geo Technical engineers to predict the performance of high buildings, and higher levels of performance. Inventory is sort of a backdrop to looking at some of the issues, so out of that inventory, three cohorts of buildings that rise up. One as i mentioned, nonductile concrete buildings, 12 out of the 156 in the Tall Building inventory, but again keep in mind many, many nonductile concrete below 240 that are hazardous. Steel moment frame buildings, 86 on the landscape before the northridge earthquake, 65 at the moment resisting frames, raising some questions about what their performance might be in future earthquakes. And finally, the last cohort is looking at the proliferation of tall residential buildings. About 24 largely reinforced concrete. And we raise these just to sort of think about what issues that can occur in each of the buildings, depending on occupancy, when they were built, type of construction and so forth. And in thinking about why do we focus on Tall Buildings, obviously these are important structures, large occupancy, but its not just the effect on the people in the building, whether the safety of them first and foremost, but if there is damage and people are displaced from an Office Building versus a residential structure. But also how damage can affect its neighbors, in terms of debris after an earthquake, how it can effect emergency evacuation routes and impede buildings around it. If there is a cordon, whether it would restrict access not just to the Tall Building but buildings in the facility. So we delved into as part of the study. So, out of the study, 16 recommendations. Wont review these all, but kind of four major categories. First is looking at what could be done for New Buildings, and one of the recommendations and several of these form the basis of discussion were brought in the mayors directive, what are some of the important ones to tackle. One of the first ones is looking at the performance and design requirements for Tall Building foundations, one i think not a topic of the Panel Discussions but already d. B. I. Is working to develop the recommendations that were recommended in this report. One that we will talk about today i think its a topic somewhat of the first discussion is to think, Tall Buildings be designed to higher performance levels than other buildings. Especially thinking about when the residential occupancy and so forth. So, some recommendation on that, i have a couple of slides to show on that, to kind of queue up that discussion. Oops, back for a second. A host of issues on existing building, what could be done before earthquakes to existing buildings, retrofit, and insurance and that forth. Third category
