First street flood mitigation project enters design phase


After a breakthrough this spring on the placement of a new stormwater treatment system to replace aging infrastructure and mitigate flooding from rising sea levels in Miami Beach’s First Street area, the design phase of the project is about to start. However, the completion of the project is still in four to five years.

Miami Beach City Manager Alina Hudak informed city commissioners by letter this week that negotiations have been completed with contractor Jacobs Engineering and that she plans to issue a Notice of Prosecution (NTP) early November to launch the design phase which should take 24 months. The project includes a new storm water pumping station, a storm water treatment system, a storm water gravity collection system and a storm water discharge pipe, as well as the replacement of a main water pipe. existing, a gravity-fed sanitary sewer and improvements from the surface area to the streetscape and urban canopy.

Hudak noted that the design fee of $ 5.98 million represents a savings of $ 1.6 million over budget “without reducing scope items.” The City has allocated a total of $ 46.9M for design and construction.

“This project is one of the first capital projects to be implemented after the City of Miami Beach Urban Land Institute’s Red Team Review and the creation of the READY team,” Hudak wrote. “The red team was made up of several professionals from the Urban Land Institute, who conducted an evaluation of the City’s flood mitigation program.

One of the follow-ups to the Urban Land Institute (ULI) review was the creation of a READY team made up of key service executives with responsibilities related to resilience and neighborhood improvement projects in the City. . Another recommendation was to combine blue-green infrastructure with “pumping systems and raised streets, both to introduce more flexibility in water management and to provide more visible collateral benefits to the local community”. Blue-green infrastructure integrates natural processes into water management and treatment, slowing it down and integrating / treating it into the natural environment.

“This will be the first project to integrate, by design, the City of Miami Beach Blue-Green Stormwater Infrastructure Concept Plan (BSI) and the Commission-approved Urban Forestry Master Plan, with the ‘hope that as the city adapts to climate change to address flooding issues, it will seek to step up the implementation of blue-green practices across the city, ”Hudak wrote of the First Street project. .

The scope of the project also includes the elevation of First Street from Alton Road to Washington Avenue.

The location of the stormwater treatment system (SWTS), the sticking point for community members, was determined this spring after four years of dialogue. The SWTS and its electrical components will be located in the parking lot at the southwest corner of the intersection of First Street and Washington Avenue.

“Since the start of the project, the City has continuously involved the community at every step of the process,” said Hudak. “The 40 stakeholder outreach meetings held over the past four years are a testament to the extraordinary level of community engagement. Stakeholder feedback led to multiple design variations, including the assessment of different locations for the proposed storm water treatment system (SWTS) and outlet.

Miami Beach spokeswoman Melissa Berthier said the launch of a project like this “usually comes 4 to 6 months after the design is complete.”

She said construction would take two to three years, she noted, “This is a rough estimate as we haven’t completed the design, but it’s based on the scope of work. “
