Mohave County is trimming its vehicle fleet with the intent of cutting costs and improving operations, public works director Mike Hendrix said.
Hendrix said he has retired 20 vehicles that each have 100,000 or more miles, adding, "We think we can do better than that."
Before retiring the vehicles, Hendrix oversaw a fleet of 239 vehicles assigned to county departments and 35 in the motor pool.
Hendrix said he has not decided how many more vehicles will be retired or how many replaced as the county enters a new budget year July 1.
He said fleet manager Noval Wright and finance department staffers are trying to decide how much more to reduce the fleet.
He said the county did not replace any vehicles during the past fiscal year and has replaced some this fiscal year.
The county has been analyzing the vehicle fleet for two years, county Supervisor Pete Byers said.
"They are doing an assessment on the motor pool for a year, I guess," Byers said.
"We have talked about everything from oil changes to gas prices.
We have talked about how often to change the vehicles."
County officials discussed the vehicle fleet during a budget workshop March 17.
Hendrix prepared a report for that meeting which broke down the ages of the vehicles, current expenses for use and replacement cost.
For instance, he wrote that 93 assigned vehicles were 5 to 10 years old and 92 had 100,000 to 150,000 miles on them each.
The average monthly fee for assigned vehicles was $100 at the time.
Hendrix projected that it would cost about $1.5 million over three years to replace 56 vehicles with 150,000 miles on them that are assigned to the Mohave County Sheriff's Office.
