  1. City of Ashland Fleet • Overview of our city fleet City of Ashland • Review of current purchasing practices • Pros and cons of alternative technologies Fleet • Our potential use of these technologies • Options for future purchasing strategies City of Ashland - Fleet City of Ashland - Fleet • Large fleet for a city of this size • 129 Vehicle in service – Three departments other cities this size do – 60 Light duty vehicles not usually operate – 46 Heavy duty/ Specialized vehicles • Electric Department – 23 Heavy equipment • Fire Department- Ambulance service • AFN Light Duty Vehicles Heavy Duty / Special Use Vehicles • 60 Vehicles in this class • 46 of these vehicles in operation – 52 Gas Powered – 29 Diesel Powered • Including 4 hybrids – 17 Gas Powered – 7 Diesel Powered – 1 Natural Gas 1

  2. Heavy Equipment Vehicle Replacement • 23 Units • Vehicle use – 15 Diesel powered • Efficiency and safety – 5 Gas Powered – Job efficiency – 2 Electric Powered – Fuel economy – 1 Propane Powered – Correct vehicle size for the application • Cost Vehicle Use • Department using the vehicle – Intended use – What type of loads will it carry, and how much do the loads weigh – How many people will the vehicle need to carry – Will the vehicle be used in more than one application Efficiency & Safety Vehicle Size • Adequate breaking for typical terrain • In a heavy duty application, larger vehicles will do the job more efficiently • Correct engine size for expected load • Correct weight carrying capacity for anticipated application • Vehicle size vs. application – Go smaller whenever possible – Can a smaller vehicle safely do the required tasks – Will a smaller vehicle be overworked 2

  3. Why We Use 1-Ton Trucks • Needed for weight carrying capacity • Used for trailer towing • Used in specialty applications – Small dump trucks – Ambulances – Snow plow/sanders – Brush fire fighting units – Sewer rodding/cleaning – Electric department bucket truck Future 2 yard dump truck 3
