ROLL CALL Present: Ms. Casey Mr. Pluhar Chair Ms. Meyer Ms. McSherry Ms. Kang Ms. Respondek Also, present: Ms. Claudia Hasbun –Planning and Zoning Director Ms. Alizgreeth Tezen –Planning and Zoning Technician 3. MINUTES (S): 3.a. Approval of the minutes October 16, 2023 https://cloud.msvfl.gov/s/jbFmsT5SRRspX2N Motion to approve by Ms. Casey, Seconded by Ms. McSherry. 7-0. 3.b. Public Comment: Mayor Burch stated that he is pleased with the committee being in attendance of last council Meeting and urges the committee to look into reducing greenhouse gas emissions based on the changes of public transit. Mary Benton spoke about the park and how she frequents on walking by the bay as well as pleased on hearing any updates on the project. 4. DISCUSSION ITEM: 4.a. Bayfront Park Sea Wall Project Update Presentation 2 Village Manager Esmond Scott started the presentation and spoke about the update on the seawall design and the project status report on how the Bayshore is being addressed. Village Manager Mr. Scott spoke about the selection of ChenMoore and how they we’re able to present a solid project to address all the issues from before and bring forth a spotlight on the engineers, consultants and all individuals that made this possible. Patrick (ChenMoore Engineer) spoke about the project scope and goals, processes, current conditions, the schematic seawall designs, the sustainability and resilience aspect and finally the timeline. Currently, the project is in the schematic design phase and stated that public information and input is going to remain throughout the rest of phases of the project. Site investigation/analysis has been completed as well as information on what the public input information entails. Patrick explained the current conditions of the seawall and provided the elevation of the existing wall and relation with sea level rise. Lenard (ChenMoore Rep) spoke about the southern segment, which shows an engineering rating of serious condition. Lenard spoke about the cracking and the condition of the current gravity wall is. The use of glass fiber reinforced polymer will be a material that will benefit the sustainability perspective. Also the seawall will meet the Miami-Dade County’s flood criteria which the minimum 6.0 feet-NGVD. The material being proposed is 25% of the weight of steel and it will have an extended lifespan aspect to address concerns of durability. The benefits of the wall will also incorporate a biodiversity enhancement and will include 3D- printed panels as well as a biomimicry aspect to have a “living seawall” approach. Patrick spoke about the next steps and stated that it would be on schedule for February 2024, estimated approval in august 2024. Chair Ms. Meyer, was pleased on the sustainability element being included in the design, the glass fiber polymer technique and the future proposal to increase the seawall in the future. Chair Ms. Meyer is more concerned on the budgeting; Ms. Casey asked about the proposed material versus the typical reinforced steel. Lenard stated that it is significantly less expensive but there is a long-term gain on using this material. Ms. Casey asked about using injectable C02 and can it be mixed with the component that makes the proposed material? Lenard stated that would be something that needs to be looked into and get an idea through the transport aspect on how to bring it on board. Mr. Pluhar asked about the life expectancy? Mr. Lennar stated that it would be about 75% more than the average reinforce steel. Mr. Pluhar asked about the biodiversity or is that a proposal? Patrick stated that it is something that can be added after the fact based on the budget constraints. Ms. McSherry asked what the park is going to look like based on the required slopes? Ms. Kang asked with the follow up question, if they’ve used similar seawall proposals in other areas? Lennar stated that this is going to be a limited installation on the project and seawalls, and it would not be the first project that has been incorporated. There are long-term examples that have been done thirty years ago and it is nothing new just more popular and looked into with other cities and municipalities. Ms. Respondek asked will there be some schematic layout that will show the paths being proposed and will this create a smooth transition for the residents? Ms. Respondek also asked would there be any stairs incorporated in the design? Patrick stated that there are no stair incorporation in the design. Ms. Respondek asked if there is any idea on costs and what has been taken out so far and what is the amount now? Patrick showed the committee where the project is currently at and will eventually show that amount after passing the first phase. Ms. Respondek asked is the number going to be the same of more? Patrick said it would be announced once there is a consensus on the schematic design and it will be included. Mr. Scott stated that a million would be from the grants. Ms. Respondek asked will there be a change on building a current seawall? No more than 12 inches into the bay and a partial demolition of the existing, which will not be visible to the current one, which will be with fill per Patrick. Mayor Burch asked about the projection on the bay being a little deeper? Mayor burch also asked, is about the allowed pillar and slab type of seawall; and if it would be interfering into the public right of way? Also, is the public is going to lose access to the walkway? There would need to be a more complicated permit process to get a state department approval and would need to get a variance to be able to infill that portion, staff stated. Someone asked how will the panels be manufactured if it is something that requires it to be done on- site of off-site? Also, how long will that take? Lenard stated that most contractors would prefer the casting area, or bring the panels already casted. The duration would take about 6 to 8 months and it will entail on the pretreatment process. The next stage will be getting it approved the construction company and bidding. Mr. Pluhar asked if they have a hurricane preparation plan? Ms. Casey asked is there any benefits for storm surge, tile waves, etc? Lenard stated that there is some reduction and in order to quantify that is difficult per 3 where the wall is located and would need to figure out a proper way to document that to be able to determine that. Vice Mayor Mr. Valinsky asked is that going to cause issues with the integrity of the existing wall? Mr. Valinsky also asked is there clarification on the weight of the steel? Is a research paper by University of Miami enough to show that the material of the wall that is less corrosive and support for this theory? Is there a distinction on both? Lenard stated there are reports and a long history of this material being able to work well. A resident asked, if there is anything based on experience that during construction of the seawall, would cause farther delays based on it going through hurricane season? Lenard stated the wall is in two types of exposure and will require a different wall section to start on before the other; in other words, it would be done in sections and for a storm of that magnitude, there are protocols in place for those types of concern. Ms. Kang added that based on the constrains and no continuations of corrosion based on the salt water that a stormwater master plan for this project will be necessary to view and analyse properly. Patrick stated that based on that design it will depend on future modifications and what will need the item. Patrick stated that he will work with staff to see what would make most sense for the Village and provide opportunity for public input. Public information is through the entire process. https://cloud.msvfl.gov/s/CoJ8YYgKZxydWTL 5. BOARD MEMBER COMMENTS Ms. Casey stated that it would be best to have in the next meeting the list of priorities based on what was presented and provide committee feedback. December 11th next meeting Ms. Meyer asked about adding in the newsletter to promote the America beautiful and an interactive quiz to urge residents to communicate with the committee and have feedback to add in the website. Ms. Meyer added she went to FIU to see the different tests and studies on identified adaptation areas and it would be a great idea on having to present the tools and technique to the village. Ms. Meyer also asked about the tree ordinance and is there a timeline for this? There will be an effort to have a new revision to coordinate with council and have a line item up for Village Council to review, staff stated. Ms. Hasbun stated that there is a draft from last meeting on encourage all the items and it will be secured once a date is presented. It would be best to bring priorities in the next meeting and it is valuable to expand the sustainability and climate paper. 6. NEXT COMMITTEE MEETING – TBD 7.
