Manatee County Enhances Flood Resilience with Completion of Automated Outfall Structures Project

Manatee County’s Storm Water Engineering Division has successfully completed the Automated Outfall Structures (AOS) project at two stormwater facilities along 17th Street East near Sylvan Oaks. These advanced systems, which can be operated remotely, are revolutionizing the county’s stormwater management approach and enhancing flood protection efforts.

The AOS technology is designed to lower water levels in stormwater facilities ahead of major storms or heavy rainfall, increasing storage capacity to mitigate potential flooding. The system recently demonstrated its effectiveness during Hurricane Milton when the new AOS at the 45th Street stormwater facility, located north of State Road 70, provided additional flood storage capacity for the surrounding area.

Building on this success, the county plans to expand the AOS technology to additional flood-prone areas, including the Bowlees Creek, Pearce Drain, and Rattlesnake Slough Watersheds in 2025. This strategic expansion further strengthens flood resilience and protects communities vulnerable to severe weather events.

Completing the AOS project marks a significant step in modernizing stormwater infrastructure and underscores Manatee County’s commitment to proactive flood management and community safety.
