FORT LAUDERDALE — Two weary flood-prone neighborhoods regularly pounded by severe rainstorms now have stronger protection against the next storm: A modern new pump station worth more than $10 million. The project, part of $50 million in stormwater upgrades meant to protect River Oaks and nearby Edgewood from severe flooding, represents a major milestone in Fort Lauderdale’s ongoing mission to upgrade its infrastructure, Mayor Dean Trantalis said. A total of 25 neighborhoods are on the city’s drainage upgrade list, but flood-prone River Oaks and Edgewood were the first in line for what will be a $700 million investment over the next decade. “This project is a key component of our citywide Fortify Lauderdale initiative, which focuses on strengthening our resilience to climate change impacts, particularly in our most vulnerable neighborhoods,” Trantalis said at a ribbon-cutting for the pump station this month.
