Fire Chief Dayton Burnside said the department now has two aerial ladder trucks and four pumper trucks. The other aerial ladder is a 1998 model, which is to be transitioned to reserve status.

"It's fine for reserve, but it's wearing out as a front-line unit, showing its age," Burnside said.

The department's pumper trucks range in age from a 2006 model to a 2012 model. Burnside said the 2006 model is due to be replaced next year.

An ISO PPC takes multiple factors into account:

» Emergency communications systems, such facilities for staffing, training and dispatching objectives, among other things

» The fire department and its staffing, training, equipment and geographic deployment of units

» Water supply and hydrant examination
