St. Lucie County Fire & EMS Frequencies

This page lists the fire-service and EMS radio frequencies on file for St. Lucie County, Florida, with the county seat at Fort Pierce and a local ZIP prefix that begins with 349xx. Whether you are a resident programming a new handheld scanner, a journalist chasing a working fire, a neighboring department monitoring mutual-aid traffic, or a ham operator on AUXCOMM duty, this is your starting point for the channels you actually need.

Dispatch traffic in the county moves on a small set of repeated channels: a primary fire dispatch repeater that carries the initial alarm, a fireground tactical channel that the assignment moves to once units arrive on scene, an EMS dispatch channel for ambulance assignments, and an EMS-to-hospital med channel where medics give entry notifications and consult medical control. Larger incidents — a working fire requiring mutual aid, a multi-vehicle highway crash with extrication, a wildland fire spreading into neighboring jurisdictions — escalate to the statewide channels documented on the Florida page.

St. Lucie County's coastal geography shapes the radio operations you'll hear on the air. VHF propagation is long over open water, so you'll occasionally pick up traffic from departments well outside the county — and during summer evenings the band can carry surprising distances. Expect water-rescue traffic that crosses to the marine band (Channel 16 for distress, 22A for Coast Guard liaison), beach-rescue and dune-grass fire calls, and during hurricane and tropical-storm season, a heavily exercised mutual-aid plan that moves apparatus and command to staging well in advance of landfall. EMS calls along Fort Pierce and the surrounding shoreline pick up sharply on summer weekends and during storm-recovery operations.

Local fire departments in St. Lucie County typically maintain both a primary VHF dispatch channel and a fireground tactical channel; coastal districts often add a secondary repeater on a hilltop or water tower for reach into low-lying areas where direct line-of-sight to the main repeater is blocked. The escalation path for incidents that exceed local capability moves to SLERS and then to the nationwide NIFOG bank for cross-state coordination during named storms.

The local agencies and the channels they typically run are listed below. From each agency page you can pull a deeper view of that department's individual fireground, tac, and EMS-side channels — useful when you want to monitor only one department rather than the whole county.
