Figure 7 Historical and Projected Funding Inpacts to Total Street System <br /> <br /> <br />Thegraph (Fig.7) ofthe combined arterial, collector and residential streets reflects the <br />recommended treatment needs for the overall street system and indicates the insufficient funding <br />for residential streets.e streets <br />requiring both reconstruction and overlay treatments increase. <br />The projected $191 million backlog in 10 years represents a majority of streets in the high-end <br />overlay ranges. Arterial, collector,and residential streets benefitting from past rehabilitations <br />often only require minimal work such as a thin-lift overlay. This treatment is much lower cost <br />than overlay costs used for the current analyses. <br />18 <br />May 29, 2019, Work Session - Item B <br /> <br />
