The City Fire Department provides collaboration with HVA EMS to asist with medical runs.The City Fire Department operates as at a basic (BLS) non-transport licensure. While HVA operates as advanced life support transport. It is not economically feasible to station multiple advanced life support (ALS) ambulances in South Lyon 24/7. If the ALS unit is out of the City, the fire department is always able to respond and provide rapid care until another out of area ambulance arrives. The savings comes from not staffing a second ambualnce. Additionally, the fire department provides additional staffing to assist with critically ill patients instead of tying up a second ALS unit. The fire department's BLS staffing is cheaper than ALS staffing.
