Fire Incidents:       28087 / 80 pieces of fire equipment (rougly)
EMS Incidents:      81842 / 30 EMS units

28087 / 80 = 351 runs per piece of equipment per year
81842 / 30 = 2728 runs per unit per year

To make the EMS runs per piece of equipment equal to fire runs,
there would need to be an additional 200 EMS units.
