LTC 450-2016 Progress Report on City's Mitigation Strategy Relative to Property Owner Flood Insurance Premium Discounts MIAMI BEACH OFFICE OF THE CITY MANAGER NO. LTC # 450-2016 LETTER TO COMMISSION TO: Mayor Phillip Levine andMembers of'he City Co iission FROM: Jimmy L. Morales, City Manager ` DATE: October 24, 2016 SUBJECT: Progress Report on the City's Local Mitigation Strategy Projects relative to Property Owner Discou4ts on Flood Insurance Premiums Introduction and Background The purpose of this Letter to Commission is to provide the Mayor and Commission with a progress report on the City's Local Mitigation Strategy (LMS). The LMS is one of the activities that will result in a discount of up to 20% on flood insurance premiums for residents and businesses in our city. The primary goal of the LMS is to reduce vulnerability to natural, technological, and societal hazards from all sources, but especially from hurricanes, tornadoes,floods,and other severe weather events. The City's participation in the LMSProgram improves its standing and classification in the Community Rating System (CRS), making flood insurance under the National Flood Insurance Program more affordable. The City is preparing a full Repetitive Loss Analysis, which is an important component to improve the City's CRS score and ultimately increase the discount on flood insurance premiums for residents and businesses in our City. Program Continuity and Strategy to Inform the Public City staff members attend the Miami-Dade County Local Mitigation Strategy meetings once each calendar quarter and review the latest published version of the LMS. Meeting times, dates, and locations are posted on the Miami-Dade County LMS website at www.miamidade.gov/oem/Ims.asp. This Letter to Commission will be posted on the City's internet and made available to the public through the City Clerk's Office. The progress report on the projects listed in the City's Local Mitigation Strategy is provided below along with a listing of the projects completed since 2005. Progress Report on the City's Local Mitigation Strategy Projects Page 2 Flooding: Drainage Improvement Projects Flooding has a significant environmental, health, and economic impact, causing businesses to be inaccessible to customers and resulting in the additional cost of replacing and repairing damaged property. In addition, due to high groundwater elevation, drainage is slowin certain areas, requiring extensive periods of time to dissipate. This has caused some paved roads to deteriorate and/or fail, resulted in the creation of mosquito breeding areas, and intensified other public health issues. In response to this, the city has changed the stormwater criteria and required all existing projects to be brought up to the 2.7' NAVD boundary condition. The city's comprehensive program of drainage improvement projects will alleviate chronic neighborhood flooding situations.

The project will also encourage homeowners to become more resilient and to incorporate climate change considerations in their home improvement projects. It will also promote the inclusion of mitigation strategies that foster community resilience against flooding risks. Status: This is a future project. Citywide Tidal Flooding Mitigation: The purpose of the project improvements is to prevent the backflow of water from the Biscayne Bay into the City's stormwater management system and up through the stormwater inlet grates flooding the roadway curb and gutter. This tidal flooding poses a threat to public health and safety, inconveniences the public, and has caused major damage to structures, and killed lawns and landscaping. In addition, tidal flooding saturates the base structure of roadways causing failure of roadways prior to their expected useful design life. This project consists of the installation of backflow prevention valves (aka `Tideflex" valves) on a majority of the PSMS outfalls to the Biscayne Bay and in the lowest lying areas of the City. Status: This project is under construction. Citywide Wastewater Infrastructure Improvements: The wastewater lines are approximately 50-80 years old. The iron pipes are increasingly brittle, resulting in hydraulic problems and potential failures. The useful life of these force mains is approximately 50 years and the pipes are either at the end of or beyond their useful life. This project will implement the city's Wastewater System Master Plan, which will replace aging lines that are 60 years old or more. Status: This is an ongoing project. Citywide Water Infrastructure Improvements: The project includes the replacement of aging water lines (60+ years old). These iron pipes are significantly tuberculated which has resulted in diminished water quality and hydraulic problems. This project is fully programmed through neighborhood projects and other projects in the City's 5-year Capital Improvement Plan, subject to appropriation of additional programmed funding. Status: This is an ongoing project. Citywide Dune Restoration & Enhancement Project: This project seeks to restore the City's coastal dune system by removing non-native vegetation, planting native species, and selectively trimming native vegetation. This project will improve the overall health and stability of the dune system so it is best suited to retain sand and protect upland structures from storm surge and flooding. The project will also install a rope and post fence system around the dune system to protect the project's results and minimize trampling impacts to the protected area. Educational signage will educate visitors about the structure of the dunes, their importance, and the vegetation housed therein. Status: On-going (maintenance and monitoring). Progress Report on the City's Local Mitigation Strategy Projects Page 9 Windstorm Storm Shutters and Protective Glass for City Buildings: The city is a barrier island that is subject to high winds, missile hazards and significant impact damage. The buildings listed below require protection for windows during a significant weather event. Status: Refer to the below for project statuses: Building Name Location Address Status Miami Beach Botanical 2000 Convention Center In the Planning Phase Garden Drive Mount Sinai Hospital 4300 Alton Road Future Unfunded Project North Shore Park & Youth 501 72nd Street Future Unfunded Project Center Log Cabin 8128 Collins Avenue Future Unfunded Project Other Hazards Acquisition of Emergency Generators: Acquisition of emergency generators to ensure continued operation of critical city facilities/systems and the appropriate levels of service for city residents during and after a disaster event. Status:This project is ongoing. West Avenue Bridge: The project is of regional significance and will help relieve congestion on State road 907 (Alton Road). A connected West Avenue would help reduce the volume of local traffic at the busiest intersections. In addition, it would provide a safer venue for cyclists, pedestrians, and motorists making their way to the causeway to Miami, than other existing venues. Status:The project has been awarded and is in the design phase. Streetlight System Upgrade: There are approximately 8,400 streetlight poles located throughout the City. Public Works is in the process of developing street lighting standards that will be used to upgrade the street lights when neighborhoods are reconstructed or insufficient lighting is addressed. Standards will be developed for average street lighting as well as individual fixtures. Lighting upgrades will also be in response to Police Department requests to combat crime and illegal activities. Status: The City has completed a citywide photometric analysis and is developing plans for strategic enhancements. Portable Traffic Light Signals: During power outages, the traffic lights are inoperable, causing a potential hazard. Portable traffic signals will provide the safety that is needed for traffic control. The city anticipates that it will need ten portable traffic signals to adequately handle an emergency situation. Status: This is a future project. Progress Report on the City's Local Mitigation Strategy Projects Page 10 Construction of new Fire Station #1: Intensive maintenance is required to continue operating the Fire Station as it exists today.This maintenance includes costs that over time could exceed the cost of full demolition andreconstruction of all facilities on site. Existing parking conditions are less than ideal, frequentlylimiting building occupants from securing parking. The existing FEMA flood elevations also indicate that under severe storm events, the Fire Station would become inaccessible and wouldprevent emergency assistance to the surrounding Miami Beach community. The City facilitated anin-depth assessment of the Fire Station, and upon evaluation of the current site conditions and minimum code requirements, fullsite reconstruction and demolition of existing structures (including relocation of the existing pumpstation) were recommended in order to mitigate potential severe hazards and provide the public with the highest level of services. Status:This is a future unfunded project. Progress Report on the City's Local Mitigation Strategy Projects Page 11 Recommendations: 1. The City will continue to participate in Miami-Dade County's LMS program and monitor the projects, as needed. 2. The City will continue to have various outreach projects to inform the residents and visitors about hurricanes and floods preparedness and safety.
