This Proprietary internal services fund is a self-supporting fund that includes the expenditures and revenues related to the maintenance of all county vehicles, except for the Sheriff’s Office, which operates its own fleet maintenance operation in the General Fund. This fund began in 2007 following the construction of a building to accommodate fleet operations. Revenues for this fund come from charge-back billings to county departments. The entire operating budget is charged back to the various funds and agencies that participate in the fleet maintenance program. Its total expenditure budget is $4,581,612.
