Unimproved Street System The City's transportation system consists of 533 centerline miles of improved and unimproved streets. The unimproved portion of this total includes 51 centerline miles (87 lane miles) of asphalt and bituminous surface streets. This section of the report is intended to describe the overall condition of unimproved asphalt streets, potential treatment needs, associated rehabilitation costs, along with a projected backlog repair cost for addressing this classification of street. It is important to note that any treatment short of being brought up to full urban street standards should be considered temporary. The estimated cost to improve this classification to meet the urban street standards is approximately $60 million. In addition, the following backlog figure is separate from the improved street backlog figure. Based on 2012 rating data of the unimproved streets system there is a backlog of temporary repair projects, typically maintenance overlays, totaling an estimated $9.8 million, down from $11.3 million reported in 2011. The following charts and graphs indicate that 45 percent of the system falls into a no treatment category, up from 36 percent reported in 2011, due in large part to recent maintenance overlay and FDR treatments completed over the past five years. More than 75 unimproved streets have benefited from full or partial treatment since 2008. Thirty three percent of the system falls into the "poor" category. Currently, Public Works Maintenance plans on spending $200,000 annually over the next four years to address a portion of these streets. 2012 Unimproved Asphalt Street Condition and Rehabilitation Report (2012 Rating Data) OCI Lane Miles % of System Condition Rehabilitation Cost Unit Cost /SQFT 0 -10 6.77 7.61% Poor $2,573,683 $6.00 1120 11.72 13.18% Poor $2,970,317 $4.00 21 -30 10.68 12.01% Poor $1,522,541 $2.25 31 -40 6.01 6.76% Fair $856,786 $2.25 41 -50 4.18 4.70% Fair $595,901 $2.25 51 -60 7.56 8.50% Fair $1,077,754 $2.25 61 -65 1.72 1.93% Fair $245,203 $2.25 66 -70 1.63 1.83% Good $0 $0.00 71 -80 2.63 2.95% Good $0 $0.00 81 -85 3.89 4.37% Good $0 $0.00 86 -90 4.75 5.33% Excellent $0 $0.00 91 -100 27.42 30.83% Excellent $0 $0.00 Total Rehabilitation $9,842,185 88.96 100.00% * Unit cost based on 2010 estimated costs 19
