She has instilled in me certa certainly values and advocacy around folks that are the most vulnerable. As were going to talk about later in the meeting, there are some significant risks we have as a city that will affect our most vulnerable. I want to say a few words about joanna. She was a trailblazer her entire life. She was the first person with a disability to attend the Public School system in her native grease. After graduating, she pursued disability advocacy work. The pacific a. D. A. Center and the city of sacramento before she joined the Mayors Office of disability in 2006. Joanna played a leading role in insuring that the implementation of the american with disability act was consistent with our citys progressive values. Her work helped to ensure that San Francisco moved closer to inclusion and full social participation of all deaf and disabled people. Joanna developed the citys first ever a. D. A. Trainers academy and she was passionate about employment, transportation, safety, and disaster planning for people with disabilities. Most recently, joannas personal testimony on what it is like being a working professional and mother with a disability helped to move s. V. 26, the aisesabil y aisesability accessibility for all act, that went to be signed in 2018. This ensures wheelchair users will have access in the future. Most of all, joannas love for her family and her kids was central to her life. She taught them the values that she lived by, that disability, equity and culture must be recognized and never separated from race and class and the voices of people with disabilities must always be heard. Her unique style and approach, her humor, for sure, will never be forgotten. I would like you all to join me in a moment of silence to honor our colleague joanna. Thank you so much. Okay, we are going to begin our official meeting agenda. Im going to be reporting out on last week, last week or so. Excuse me, heat response for the days of june 7th to june 11th of this month. So, as everyone knows, i dont need to tell you, most of you were probably here, it got really hot in San Francisco. Unseasonably high heat caused Public Health to initiate their extreme heat protocols. These included regular daily d. E. M. , instant management calls that we initiated with the National Weather service and lead agencies, many of whom are here today. We issued as a city, daily situation reports, capturing expected temperatures and alternatives to City Services based on the citys heat response. We identified facilities for public cooling and there was a robust public outreach, including Community Based organizations which we will hear a little bit later when the mayor is here. What happened in San Francisco . So we did all of this outreach, but really how did it affect us . We had a surge in the 911 system, which required the need for incounty and out of county mutual aid for ambulance services. The last time this happened was in the 2017 labor day heat wave. Fortunately, our mutual aid plans were implemented and worked like they were supposed to and we were able to manage the surge. The next step we are working on is take a close look at the data to see where these calls originated from, who were the most impacted by the heat, so that we can preposition and put our resources to where they are most needed. All of this calls for a greater understanding and prior authorization of our built environment. The fact is that the majority of our facilities and infrastructures are not equip to handle this kind of heat. While other cities in california can handle 90 degrees and up, and its not an issue, why is it a crisis for San Francisco, and that has to do with our own environment, as im sure you all know. Were working with the city administrators office, and we will continue to look for solutions, not only shortterm, but midterm, and longterm strategies to address and improve our capent capabilities for providing air quality relief and looking at longterm potential solutions for adaptation to these new Climate Changes and extreme weather that were experiencing. I want to thank everyone, all of my colleagues that came together and got us through this and we will be working on this a lot more and we have some more conversations on this when we get to the Public Safety shutoff and air quality issues that are on the agenda further. At this time, the public may address the entire Disaster Council for up to 2 minutes on any item within subject matter that is within jurisdiction of the council. So this is general Public Comment. Do we have any members of the public here that wish to comment . Okay. Seeing none, we will move on. So, we are lets see, excuse me. So, mayor breed will be joining us in a little bit and at that time, we will pause the meeting for some special accommodations. Now were going to ask brian, where are you . There you are. Can i jump in real quick . Yes, please. Am i on . Hello . Okay, well, there you are. I just really want to as we start off on the Tall Building strategy, which is the topic thats up next. I really want to take the time to say this started up in 2017, mayor yee asked the director of emergency management, the d. B. I. And the Public Utilities commission to come together and create a Tall Building strategy for our Downtown Neighborhood, not just downtown, but our financial district and as we see it, its merging into mission bay now. As were thinking of all our Tall Buildings. Its one of the strategies in our earthquake implementation program. Tall buildings was one of the initiatives we would think about after private School Evaluations and we worked with the applied Technology Council to find academics in the world, and engineers who have not touched any of our Tall Buildings in downtown San Francisco, who can give us an objective, thought about how we should think of our buildings, not just how we survive an earthquake, but how do we make them more resilient because more and more people are living in the Downtown Neighborhood of San Francisco and we need to rethink not only our building codes but our Recovery Plans and how many engineers we have who are certified to be inspectors and to think through our resilience of downtown San Francisco. I really want to thank boma for being an active participant. This tuesday we had mayor breed ask us when we put out the Tall Building strategy in october, she first and foremost wanted us to outreach to all the stakeholders and to go into other cities to get best practices. Boma who has been a great participant with us, thank you for that. There is a lot of great work that came out of this and brian and his team, Danielle Miller had led the effort and how were looking at them shortterm, midterm, and longterm, and how we implement those recommendations. Yeah, thank you very much naomi and thanks. Im happy to be here, the third time is a charm. I think as i seem to get pushed off the agenda, they had us go first, which is great. Naomi covered some information in the first few slides so i can move through it fairly quickly. You should have hand outs and i apologize if you cant see the screen up front. This project was initiate in 2017. It was a lot of this was work that weve been thinking about around building performance, but also around downtown is a different part of San Francisco. You know, emergency plans and Recovery Plans in downtown are going to be different than what youre going to see in the sunset district or in other parts of town, clearly because of the infrastructure there and the tall complex buildings and the impacts they may have. That was a big reason we wanted to do it. Were the only jurisdiction were aware of in the country and around the world that has looked at Tall Buildings and earthquake impacts on Tall Buildings. So, if i move through the presentation here, naomi mentioned the motivation for doing it and then if we talk about our 30 year cap plan and lot of this falls into that area of do we, you know, of enhanced building performance and how we think about it and our existing building stock. Its easier to think of making changes to future buildings, those not under construction, but what do we do about the vast number of buildings constructed in the last 100 years. So we look at these different buildings and map them out and spent a lot of time with a number of engineering students that went to d. B. I. And poured through 165 different records for Tall Buildings. These are buildings that are over240 feet, and this sort of shows graphically where those buildings are. The colored ones in the middle of the map on the left are the Tall Buildings, the red ones are 240 feet, but then you can see the other ones that are in excess of 75 feet. 75 feet is another important number because thats how the Fire Department defines Tall Buildings, and correct me if im wrong, i think its how high a ladder can get from a ladder truck. They can get to 75 feet, but beyond that, the ladders arent effective. So thats the other marker were thinking about. If we go to the next slide and we begin to look at again, this is focusing on district 3 and 6. You can see the percentages of office and residential buildings that were having in there. So the lighter colored or the lighter color in the bottom right corner there, you can see the hotels, mixed use, residential, there are some medical facilities in there and the darker ones, the blue ones, the more traditional, what you have been thinking of office or retail. So originally downtown 20 years ago, during the weekends, it was a ghost town. You can find parking there, it was easy to get around, and now you know thats no longer the case. Thats because we have really changed it from being beyond business to residential, but that means those buildings are occupied 24 7, not just 8 hours a day. It has a lot of implications for infrastructure and the types of People Living in downtown, and also the impacts on the communities that surround it. Chinatown, soma, those communities that have been there. If we go to the next slide, you can see the different types of occupancies im talking about. So, primarily the residential are moving south of market. Theyre the red buildings. We dont see as many of those in the northern area, closer to north beach. The red ones down below, you are typically in areas where we see a lot of action throughout downtown. You see that shaded on the graphic there. So, thats one of the considerations that we had and San Francisco in 2007, i believe, was the one that we actually started implement performance standards for Tall Buildings. In other words, when you wanted to construct the Tall Building, you had to verify it with having it being peered reviewed to be verified. We updated those in response to the millennium tower. So that is happening and we actually been leading the way on having this performance standard. Those are the buildings were not so concerned about. Some of the buildings more in the blue area are older, pre1990 steel frame biddings where we found after north ridge, there were issues with the connectors, the wells. Those showed up and there were concerns that we may have similar buildings where there is still a lot of debate, even among the Engineering Community and how dangerous these buildings are, but there is certainly we want to look at and something were going to follow up with. If we go to the next slide, we sort of look at some of those Structural Systems that are in, and i mention this is the greenish one, the steel Frame Buildings we want to follow up on, and i think i already covered the sheer wall, which the orange ones, its a mixture of concrete and sheer wall, that we have confidence that those buildings will perform well. Those are our recently constructed buildings. What are the building types we discovered after the north ridge quake are problematic . Yeah, those are the steel moment frame ones. Those would be the green ones that are down below. Again, there are some questions on how dangerous these buildings really are and there have been some antidotal evidence showing that it may not be so bad but, again it requires more exploration. As we go to the next slide, you look at building foundation. There was a lot of discussion on every building should have peers that go all the way down to the bed right or wrong bedrock. There are two buildings that go down to the bedrock. Those are the black ones in the middle. We have a lot of other buildings that are map foundations or map piles, which we expect they will perform very well. So i think that was one of the things they wanted to talk about in the report as well, that you dont have to go down to bedrock, its not necessarily a result in a better building or performance. So, there are a number of factors they talk about, the depth of rock, like we were saying, the soil type, and you know, whether its liquified, and the type of soil thats there, building height, the slope of the lot, the adjacent structure, grown water level, we know were having issues with the water level increasing and sea level rise, thats something were following as well. We know that there is a lot of dewatering that is happening with a number of buildings in downtown on a regular basis. So, from this analysis we developed a number of recommendations. There are 16 of them in the report and i wont go through all of them. Ill just mention you know, the mayors executive directive they focus on what is the more important shortterm issues and lot of them are around this regulations for geotechnical issues and they have begun to issue information sheets for their staff, and we expect those to return into administrative bulletins which requires a more lengthy process to implement. A lot of those will be around making sure we have the proper pier reviews and higher design standards. If its a Tall Building, maybe it should be beyond code. For most of you, you may not be aware if you build it to the code, that means it will survive after an earthquake. Its not necessarily built to be reoccupied immediately after the earthquake. So there are some discussion, and we seen it at 181 fremont and some other buildings where theyre goingon the code. Were going beyond the code with our city buildings. Fire and Police Buildings are required to go beyond code, but thats another part of the discussion, when would it make sense to go beyond code . Certainly part of that is how much did the building shake and you want a little bit of flexibility in the building, so that the structure will stay with it, but if there is too much flex ibilitflexibility, th nonstructural component of the building could fail. We have some components that are innovative requiring certain levels of stiffst in stiffness in the building. Thats something they have been doing in other parts of the world for a little while. Finally some of the other executive directive ones. I think this is more to the work that were doing here at Disaster Council, around the state Safety Assessment program and how were able to get buildings back up and cleared after an earthquake. That was a part of the decisi decision discussion on tuesday, where a lot of folks from different parts of the state around whats the best way to evaluate our buildings. There respect arent a lot of cities that have buildings over 240 feet. You cant take a person that comes from, you know, potentially an engineer from santa monica thats not use to looking at Tall Buildings and then have them look at our Tall Buildings. There are questions on how do we make sure we have partnerships that have people to evaluate those buildings. So another big part of it is looking at a downtown Recovery Plan and recovery framework. Ill go to the next slide here. The reason for this, i think there are many, thinking of different events that have happened, and the other reason is you think of downtown. Were looking at the Tall Buildings and we want to understand the context of those Tall Buildings, where are they sitting in . You can see the red on this scatter plot here shows those buildings that are higher and you can see by age, a fair number of them are relatively new. Your building may be perfectly fine, but in the building across from you fails and you had to cordon off that building, then your building may be perfectly functional will not be able to be occupied or used. So there are implement implications for the building owners and the neighborhoods around it. We wanted to think of chinatown, soma, mission bay, those areas that are communities where a lot of people live and i should mention, were also going to look at the demographics of people in the Tall Buildings and lot of them are seniors, older people, people with disabilities where the idea of living in a
