Fire station 4 was built in March 2008 in partnership with the Florida Department of Transportation (FDOT). The new station was built because the original station was over 40 years old and could no longer house the personnel and the newer equipment needed to serve the community. Fire Station 4’s response area includes residential, commercial, industrial and the Treasure Coast International Airport. The station is located at the airport and is equipped with an Aircraft Rescue Fire Fighting (ARFF) apparatus, specifically designed to respond to aviation emergencies. The response area includes small strip malls, convenience stores, boat dealerships, storage facilities, small motels and various restaurants. There are over 100 industrial businesses in the zone making it the largest in the county, and one of the most hazardous for potential fire and hazardous material threats. There are three large boat-manufacturing plants, a large automotive parts distributer, three large freight companies and one natural gas pumping station. In addition, the Florida East Coast Railroad passes through the area two to three times a day with various hazardous products.
