| | | | | | | | ANALYSIS
| The City of Miami Beach is committed to preserving the welfare and safety of its residents, visitors, and businesses. One way that the City meets this goal is by adapting its infrastructure to sea level rise and climate change.
Neighborhood Improvements, which include improvements to the stormwater system, are currently in the construction phase at Indian Creek, in the design phase at West Avenue and in the planning stage at First Street between Alton Road and Washington Avenue.
The Indian Creek Drive Flooding Mitigation Project, Phase III is currently in the construction phase. A contract for construction services was awarded to Ric-Man Construction Florida, Inc. Construction commenced during the week of March 2, 2020 and is approximately 30 percent complete. The project is expected to be completed in early 2022.
As construction has progressed, the project has experienced changes as a result of unforeseen field conditions and requests from residents. Portions of the old seawall along the Indian Creek Drive are deteriorated and the sheet pile wall that supports the road structure is damaged or nonexistent, requiring installation of new sheet pile walls. The lack of seawall along Indian Creek, is also causing changes in the design of the improvements such as additional rip-rap, new pump station support system, aluminum railings around the bus bays to ensure the safety of the pedestrians, new modified barrier wall, and light pole foundation modifications. Subsequent to requests from residents, on June 6, 2020, the City Commission accepted the recommendation of the Land Use and Sustainability Committee to relocate the project’s auxiliary power generator and provide screening. The current estimated additional cost is approximately $6.5 million.
The West Avenue Improvements, Phase II project is currently in the design phase and represents a comprehensively defined Neighborhood Improvement program, focused on resolving challenges associated to climate impacts and ancient infrastructure. A contract for design/build services was awarded to Ric-Man Construction Florida, Inc. The design is expected to continue through spring 2021 and continuing with the permitting phase. The current anticipated start of construction is toward the end of 2021.
The project budget has been impacted by regulatory requirements, design storm upgrades and the relocation of the proposed storm water treatment system. Miami-Dade County’s Department of Regulatory and Economic Resources (DRER) has made a recommendation to include additional water quality treatment to address the first inch and a half of run-off from the stormwater system prior to discharging. The project, as a result of the 10-year storm drainage model, has increased pipe and structure sizes to accommodate the new water flow design levels. Finally, subsequent to requests from residents, on October 28, 2020, the City Commission resolved to relocate the project’s storm water treatment system including all above ground components to 1671 West Avenue (City Parking Lot P24) with the discharge outfall at 17th Street and Collins Canal. The current additional estimated cost is over $15 million.
The First Street project, currently in the planning phase, has been presented to the community for review and feedback. Feedback received included requests to change the intended location of the storm water treatment system. Additionally, as a result of feedback from DRER on other projects, it is anticipated that additional water quality treatment will be required. The potential budget increases required for this project could exceed $5 million.
The approximate additional funding required for the three projects is:
Indian Creek $ 6.5 M
West Avenue $15.0 M
First Street $ 5.0 M
Total $26.5 M
Administration would like to discuss the current available funding sources and recommends funding these projects utilizing the Resiliency Fund.
