BACKGROUND: Streets Inspected Annually The Engineering Division inspects and rates approximately 1/2 of the City's streets on a yearly basis. The results of these inspections are input into a computer database which is used to project the future condition of the streets based on their current and historical condition, and surface type (i.e. brick, concrete, asphalt, etc.). This data is then paired with available funding and is used as a basis to aid City Engineering in the preparation of the City's yearly street improvement program. Staff then determines what type of improvement would be appropriate for each street. Project Description The 2017 project will perform mill and overlay work on portions of Mound Road. In total, 5.46 lane miles of the City's 825 total lane miles will be rehabilitated as part of this project. Crack sealing will also be performed as part of this project to help preserve streets and extend their lifespan.
