Table 2 below provides a comparison of the trash and recycling truck impacts and the allocated street maintenance cost for the current open competition system and a districted collection system based on these assumptions. As shown, the associated impacts and allocated pavement maintenance costs for a districted system are essentially half that for the current open competition system based on the noted assumptions. The effect of changes to the assumed number of vehicle passes for the open competition system and/or a districted collection system listed above can be determined using the information Section 2 - 5
