Replacement Cycle

A replacement cycle is a policy statement: sedans at so many years or miles, plows at so many, apparatus at so many. Applied across the inventory it produces a schedule, and the schedule is what makes fleet capital plannable instead of reactive.

A cycle expressed only in years or only in miles will be wrong for a public fleet, because so much of the equipment is used in ways neither measure captures. A parks truck that idles all summer and a highway truck that runs interstate miles may show identical odometers and be in entirely different condition. Most workable policies combine age, usage and a condition assessment, and treat the first two as triggers for the third rather than as the decision itself.

The pattern to watch for is the replacement cliff. Buying a large batch in one good budget year creates a cohort that comes due together, and the jurisdiction faces a bill it cannot fund in a single cycle. Deliberately staggering purchases costs a little efficiency and prevents a lot of pain, and it is easiest to do before the cohort exists.

GFOA’s guidance points the same way, asking governments to hold a full asset inventory, assess condition on a regular cycle, and establish an ongoing source of funds for renewal and replacement rather than finding the money when an asset fails.
