Standing water forced the closure of multiple Port St. Lucie roads on Thursday as a fresh round of heavy rain soaked the city, with Public Works crews scrambling to clear clogged drains and lower canal levels before the worst of it hit. Portillo Road shut down at Bersell Road, Bisbee Street closed at Portillo Road, and Greendon Road was closed at both Morningside Boulevard and Gowin Drive as water pooled across low-lying neighborhoods.
The city confirmed it remained under a Flood Advisory until 4:30 p.m. Thursday, with up to an inch of rain having already fallen by mid-afternoon and another half-inch to an inch expected in areas with poor drainage. As reported by WPEC, officials also closed California Boulevard between Plantation Terrace and Venus Street, along with Savona Boulevard at Parma Avenue, as water pooled across the roadway network. Drivers were encouraged to avoid the affected areas while crews worked through the closures, and city officials said they would continue providing updates as conditions changed.
Crews Clear Drains While Water Pools on Major Corridors
Beyond the street-level closures, the city's own weather advisory flagged ponding and standing water on several major arterial roads, including Thornhill Drive, Floresta Drive Phase III, Crosstown Parkway at Broadview Street, Lennard Road at Melaleuca Road, and Airoso Boulevard at Port St. Lucie Boulevard. Many of those corridors connect dense residential subdivisions to U.S. 1 and Interstate 95, meaning the flooding rippled well beyond the immediate neighborhoods where it formed. Public Works crews spent the day inspecting and clearing drainage inlets and grates while lowering water levels in city canals and retention ponds wherever possible to manage the runoff.
The scale of that task reflects the sheer size of the system crews are responsible for. Port St. Lucie is Florida's sixth-largest city, maintaining more than 925 miles of roadways. Officials have repeatedly urged drivers to follow the “Turn Around Don't Drown” protocol, warning that standing water over roads and swales can easily conceal submerged debris, washed-out pavement, or active currents.
A Flood-Prone Intersection With a Long-Term Fix Years Away
Two days before this week's closures, heavy rain submerged vehicles at California Boulevard and Savona Boulevard, an intersection that city records formally designate as “known to flood for prolonged periods,” according to Port St Lucie Talks. That intersection sits at the center of a planned $32 million Oak Hammock Watershed drainage project, whose plans include a 9.6-acre pond, a pump station, and raising the intersection. Engineering work is expected to continue through summer 2028, and the project is expected to be completed in summer 2030.
City leaders took a first step on the project in August, when the City Council approved a $2 million design contract for Oak Hammock Watershed and raised the city's yearly stormwater assessment fee from $183 to $189 per property. The $6 annual increase is meant to help fund five major stormwater infrastructure projects across the city aimed at reducing localized flooding and protecting property values. For residents watching cars stall out at California and Savona this week, the timeline underscores a familiar tension: design is still underway, and the project is not expected to be completed until summer 2030.
Broader Infrastructure Concerns
The flooding also highlights infrastructure concerns across St. Lucie County.
This week's closures are far from the first time Port St. Lucie streets have turned into a public safety concern during heavy rain. In September 2024, floodwaters trapped a school bus in the city and forced emergency responders to evacuate six children, a previous emergency Hoodline reported.
For now, city officials say the immediate priority remains clearing drains and monitoring water levels as the advisory plays out, with Public Works continuing to attend to the flooding and road closures as they arise. Drivers are still being urged to steer clear of the affected roads until the water recedes and crews can reassess conditions.
