KISSIMMEE, Fla. — City commissioners voted unanimously to double the price of calling for an ambulance. The No. 1 reason is due to the increase in gas prices. Not one commissioner protested the increase. The EMS call volume is more than 10,000 calls a year in a city of 20 square miles. The new proposed fee could be $700 per call with a $10-per-mile transport fee. However, Kissimmee does not charge an EMS tax like most cities. Commissioners expect to increase the price of ambulance services every two years.
