The National Fire Protection Association recommends replacing front line engines every 15 years and trucks every 20 years. Many of our vehicles are approaching or over the recommended serviceable life. In addition to the age of the vehicle, many of our apparatus are also becoming high on mileage; for example, engines 63 and 64 both have over 120,000 miles. If and when a referendum were to pass, some of the revenue would be used to catch up with and maintain our vehicle replacement plan.
