GREEN BAY, WI - The City of Green Bay's fleet of vehicles has hovered around 400 vehicles for the past several years, according to the Green Bay Press Gazette.

The city vehicle fleet has increased 3 percent in the past five years. City officials said they work on maximizing efficiency, and the vehicles are necessary to perform job duties.

The vehicles are assigned to seven departments based on position. Fifty-one vehicles are allowed to be taken home during nonworking hours, but are not allowed for personal use. Administrative employees are charged $3 per workday to use the take-home vehicles.

Mayor Jim Schmitt is assigned a take-home vehicle, and the city keeps a 1997 Dodge Grand Caravan on record for emergencies, according to the Gazette.

The police department has the most take-home vehicles of any department, with 17, primarily assigned to school resource and K-9 officers.

Almost 34 percent of the city vehicle fleet is assigned to the Department of Public Works, but only 6 percent of those can be taken home by employees - and only operations director Chris Pirlot takes one home daily.

Bill Landvatter is director of the Green Bay Parks, Recreation and Forestry Department, which has a fleet of 74 vehicles; seven are assigned to employees to take home.

The parking division is the only fleet department with no take-home vehicles.

Requests for additional and replacement vehicles are included in the city budget, which requires City Council approval.

According to 2009 figures, the city's annual gas bill totaled a little more than $1 million.

Last year's gas bill was the lowest in at least four years, attributed to lower gas prices - especially among diesel fuel, according to officials, reported the Gazette.
