* U& 4 4, im --QM. ** W -M Thai WW& M t <br />(Table Courtesy of the <br />University of Michigan <br />Transportation Research <br />Institute) <br />Schwartz devised a formula using these factors. He then factored in the life expectancy of a <br />Roseville street and the cost per mile of reconstructing that road (approximately $500,000 to <br />reconstruct one mile of 7 -ton street). Using his calculations he said by limiting the number of <br />garbage trucks on a Roseville street to approximately one hauler, it could extend the life of the <br />street 5 to 10 years. And based on the assessment charged to a typical homeowner that could <br />save the homeowner twenty to forty dollars a year. <br />The report from. the University of Michigan also shows that repeated starting and stopping (espe- <br />cially stopping) will increase the damage to streets by 50% to 100% depending on the speed of <br />the truck and the weight of the load being carried. Trucks with few stops on a block tend to be <br />traveling faster when they begin stopping. <br />Alternative Systems <br />Cities such as Minneapolis that have municipal collection have been using city crews and trucks <br />for many years. To start up a system of municipal collection would require a significant invest- <br />ment of money to purchase the trucks and hire the additional staff. That is why few if any Min- <br />nesota cities continue to use or are switching to municipal collection. That is also Why the <br />Committee chose not to consider municipal collection as an option. <br />However a number of cities are continuing to use or are switching to other forms of organized <br />collection that use private haulers. Organized collection of waste is when a city arranges for <br />collection services on behalf of residents. Cities do this for a number' of reasons including <br />lowering costs to residents, lessening truck traffic on city streets, designating a disposal facility <br />for the garbage in order to meet environmental goals, setting enforceable customer service stan- <br />dards and expanding the number of services available to residents. Organized collection is <br />cheaper for residents because haulers are able to save money with the more efficient system of <br />collection and that savings is passed on to residents. <br />43 <br />M <br />
