SFGTV Government Access Programming July 13, 2024

Now of drafting the document. In fact in two or three weeks we will have an internal draft out. And then in about three weeks, three to four weeks well have a Public Comment draft that will be available. And then in december well be submitting it to fema. So that was a lot of information. I hope i didnt speak too quickly. But im happy to answer any questions you may have before passing onto adam who will talk about one of the big strategies that the hazard resilience plan is proposing and wants to see moved forward. Thank you. Good afternoon commissioners. Adam from the planning department. And im here to give an update on the Sea Level Rise vulnerability and consequences assessment. Its actually a good thing we had brian start because the hazard and Climate Resilience plan he presented is sort of looking broadly at the climaterelated hazards that are affecting the city. And this work, it started earlier because we were thinking about Sea Level Rise and we werent necessarily as aware of some of the other climate hazards. But it really nests within that. And its sort of a deeper dive into Sea Level Rise as a specific hazard. So just quickly i work for the planning department. I work in the Citywide Planning Division where the city comprehensive or Long Range Planning and policy function. We work on a variety of topics anything from housing to transportation, land use and community plans. We work with the board on a number of those major developments with design and resilience and sustainability. Its all underpinned by the authority of the general plan, which we kind of steward and maintain. So this fits obviously within the resilience bucket. And so im going to talk a little bit about the background on our Sea Level Rise plan. You will have heard some of this before but its sort of a refresher and update. Some of the methodology of what we use to develop this study, youll notice a lot of similarities to the methodology the process that brian just presented. Some of the key findings and some of the specific findings as they relate to Port Infrastructure and then finally a couple of our next steps. So by way of background, in 2015 then mayor convened a group of agencies to form the Sea Level Rise Core Committee to think about the current and future impacts of Sea Level Rise and coastal flooding on the city. It involved a number of agencies. It is chaired by brian strong who just presented, and my boss emery rogers. One of the first kind of products the committee developed was a Sea Level Rise action plan, which came out in 2016. You can see here the vision from that plan to make San Francisco a more resilient city in the face of Sea Level Rise. And that plan also set out a series of steps of what we should be undertaking to help the city become more resilient citywide to Sea Level Rise. So the first step there was to review and understand the science involved in Sea Level Rise. And what we should be expecting and projecting out by the end of the century. We have done that and worked with folks in both the state and our local government to do that. And then the next step is to assess the vulnerability of the city and the risk of the city to Sea Level Rise and what are the consequences. So similar to the hazard in Climate Resilience plan, we are looking at vulnerability and consequences. And thats the report im going to present on today. And we are going to have a final draft and expect to be publishing it within the next month. From there we will be working to develop strategies adaptation plans and strategies in implementing those over time. And as you are probably familiar, working with the port theres already a lot of work in the realm underway even as we continue to have a greater understanding of whats vulnerable and what the risks to the city are. So just a little background, what weve been using in terms of methodology these are Sea Level Rise projections. These come from a 2012 report of what level the Sea Level Rise we should be expecting over the next century or by the end of this century. You can see as time goes on, the range gets wider because less is known about how much carbon the world will emit and what the feedback loops will be. So the ranges of Sea Level Rise get a little wider. And we are looking at an additional 40 or so inches of storm surge and tidal surge. So the upper range we looked although was a Sea Level Rise of 108 inches above knee high water. So thats what our report was based on. And we looked at ten different scenarios within that range from today to 108 inches. Since we were well underway on this report, the state has updated its guidance and revised those ranges. The nearer term wasnt really change. The longerterm ones projected out a wider range including a higher high end which we havent looked at. Its not a huge amount of different area for San Francisco because we are already capturing most of the areas that are former fill areas and the city starts sloping up beyond that. So we are not talking about a significantly different area. But we want to acknowledge the state revised their projection process. So what do we do in this report . We looked at exposure first based on those scenarios and what would be exposed and we looked at the vulnerability of cityowned infrastructure and assets. I should say publiclyowned because theres noncity entities as well. And vulnerability is really a consequence of both the asset sensitivity, an electrical substation would be highly sensitive. A park might be less sensitive. And adaptive capacity, what is the ability of an asset to adapt to flooding or sea level removeable objects are there things that can be doneesly or are they more fixed. And finally we looked at consequences on the economy. This is the same hazards as brian just described. This maps shows the vulnerability zone. This is the area of the city that would be exposed within that 108inch Sea Level Rise scenario. And what the orange circles represent is where there is work underway or active projects that will build Sea Level Rise adaptations into their project. So this shows the city as it is today. But as you know, we are building out a lot of the waterfront, particularly the southeastern waterfront. Projects are building adaptations as well. So this map changes over time as projects get built. Next we looked at vulnerability and consequences across a number of sectors. You can see here utilities, Public Safety infrastructure, transportation across a number of different roads, open space and port facilities and Development Projects. And we also looked at it we also took a different slice of the same information but its how do these systems interact at a neighborhood level. So we looked at all the neighborhoods in the city that touched on a shoreline and their individual profiles for each of the neighborhoods and how do the different systems that get affected impact each other. So for example if a bridge goes out that impacts other transportation infrastructure and the ability of people to access various different things. Our key findings, these are just numbers of people businesses, jobs and infrastructure at a very basic level of what would be impacted over the ten scenarios you can see its pretty significant. Again, this is with no action by the city. This is if Nothing Happened between today and the end of the century and we didnt do anything, this is what would be impacted. This is to give a sense of the magnitude of the area and whats in the area that would be affected. Of course we are working already on addressing some of these issues. And then we identified a few sort of themes or high level issues that really kind of rose to the top in terms of things we need to be thinking about. So one is sort of transportation impact. Its important to note here that this is both local and regional and requires governance and collaboration efforts from across the city. But it also involves cal train transit terminal major pieces of the infrastructure, the embarcadero station or various yards within the Sea Level Rise exposure zone. The significant loss of shoreline open space, particularly on the eastern side of the city, which is a pretty valuable resource for communities across the city. Its a good amount of area. On the one hand, this is the type of infrastructure that Sea Level Rise can creep up without major disruptions. On the other hand, it is a major resource for people across the city. We talked about new development and the adaptations that some of these Major Projects like mission rock or pier 70 are doing, at the same time the science continues to evolve as we move along in time, well know more about where those curves will go. And we may need to revisit some of the reimers or risks of those developments as well and. And the last two are i think very crucial one is to really think about holistically the joint risk from both overland prescription precipitation flooding where you have at odds needs of what you need to do. With overland flooding you need to let the water out. With coastal flooding you need to keep the water out. So thats become an engineering issue and something to think about in some of our lowlying areas particularly around mission creek. And lastly i think brian alluded to this but as sea levels rise, groundwater levels rise. At some place it may emerge out of the ground and it impacts the potential to mobilize contaminants in formerlyindustrial areas. Its largely an issue in the eastern side of the city. And this is an area we need to do additional research. We dont know all of where the groundwater would rise, and we need to keep looking at that. So for each of the shoreline areas we developed maps like this. This is a lot of information. This is just sort of an example showing the financial district and all the different aspects that are publiclyowned within this district that would be affected. So you are looking at embarcadero, muni station the building we are standing in, some Public Safety buildings, the muni light rail and various piers and port structures. Heres another one from the creek where you have a treatment plant, you have various port cargo facilities. You have a number of muni maintenance and storage yards. You have the bridge over the creek. How do these systems impactinteract with each other. It doesnt happen all at once, it doesnt happen overnight. Although in some cases it could be more stormdriven. In some cases we are seeing flooding today. In the creek you can see the area where the numbers 7 and 8 are by the top, theres a muni yard there and that yard flooded in past year during a minor storm event combined with more higher tied. Tide. These are just a couple examples im showing you today. The last piece is more of a deep dive into the port facilities themselves. So we looked at the port multihazard Risk Assessment for the Seawall Program is looking at the embarcadero facilities. So this report actually is not looking at this. This is looking at the southern waterfront facilities and what would be impacted there. And we looked at it across a number of categories, port structures which is Historic Buildings shipping piers open space, which is self explanatory. Transportation which is varied and the Ground Transportation links to port facilities. A stormwater sewage infrastructure and ongoing adaptation projects. Heres a couple examples of maps we have produced. You can see the faint blue line showing the 108 inches. And you know, the entirety of the jurisdiction is captured within this line. So were really seeing that all the port facilities are potentially at risk from Sea Level Rise and coastal flooding. And so this is showing all the port structures that are there. The map on the right is showing the port open spaces. And we have those across those other categories as well. And so finally just some kind of highlevel key issues that sort of emerge from this report, from this analysis and findings. Not surprisingly, you would see a lot of maritime facilities and industries. And that would obviously impact port and related jobs and services that these facilities provide. And for all of these the degree of impact is obviously driven by the elevation of the port facilities, by the condition, by how they are used and whether it will be temporarily on permanently inundated across a number of scenarios. So different facilities become vulnerable at different scenarios depending on how high up they are. Port facilities play a critical Emergency Response function in terms of both staging areas and areas for people to aassembleasemiassemble or evacuate. So that would have a big impact on the citys ability to recover from a natural disaster. Shoreline open spaces are at risk and this is a valuable resource and access for the for the city. Dependence on access to transportation links both ferries and ability to access ferries. But also the links to the port cargo and industrial facilities, the road and rail and port facilities would be impacted as well. And finally, the number of the piers have stormwater utilities that run under the deck of the pier. And this would be a greater corrosion, tidal debris and inundation and that would impact the citys ability to let stormwater out to the bay and could potentially affect water quality. So in terms of next steps, we are working holistically to think about not just Sea Level Rise but kind of all of our climate hazards through the planning work that brian was just talking about. We are moving into the sort of four, five, six of that. Or at least four largely. So some of the other aspects we are looking at are resilience building codes and guidelines for both existing and new developments. How do we develop a resilient capital plan and Funding Program for what is going to take to make these adaptations. And then developing adaptation strategies, kind of at the neighborhood level. All this information i presented to you is really sort of internal city information that we then want to take out to the community and say heres what we see as at risk. And what are the priorities and values of the community and what should we do about that and how does that manifest in your neighborhood in terms of what types of adaptation strategies. So to that end we are working with the port on their resilience efforts for the sea well. We are working on the ocean beach adaptations where those are more localized, communitybased planning processes to develop adaptation strategies and projects. So with that that concludes my presentation, and im happy to answer any questions. Thank you. Is there any Public Comment on this item . Seeing none, Public Comment is closed. Thank you. Having watched how the city has progressed on this effort in terms of both resilience and Sea Level Rise, i think todays update and presentation has shown tremendous amount of progress. So i really appreciate both brian and adam coming and showing us i think its very important its longterm and strategic but obviously we have to address it. And seems like with some of the things we see across the country and just in terms of the weatherrelated hazards that we all know even most recently are affecting the state more and more. So these are important topics. I guess i dont have any questions about how you are going about it or what you are trying to do. I have just a couple questions to understand given that we are not the only coastal city, that obviously we have a lot of other we just heard about seattle earlier in executive director forbes report. How would we compare where we are at this point in understanding these issues related to some of our counterparts in other cities. And are we sharing knowledge on an active basis . . We are kind of in the thick of it and other counties around the bay area have kind of progressed further. They just released an adaptation framework so they are at the the next steps San Mateo County is also at that next step. They had some informal conversations with other cities. And brian can talk to that more. But we have also been working and i didnt mention at the regional level with bcdc who is doing this work at the regional scale. So we are trying to coordinate what we are doing with what they are doing too. And as i mentioned some of the neighboring counties are ahead of us and others are not as far along. I would just quickly add san mateo is kind of ground zero in the bay area, because they are the most impacted by Sea Level Rise getting it on both sides the bayside and oceanside, sort of like we are but more vulnerable especially with some of the issues in pacifica and so forth with losing the the deterioration of the shoreline. Right. And the other we are also i was at a uti coastal resilience conference recently. There is a lot happening all across the state. San diego is doing a fair amount with their port as well and looking at trying to use more green materials not necessarily changing their seawall but trying to use different types of materials than the typical riffraff thats been used. And then i would say across the country a lot weve been learning a lot from florida and the miami beach, miami ada, that area dade, they are experiencing Sea Level Rise more than anywhere else
