Unimproved streets are those with soil, gravel, or asphalt mat surfaces that have typically evolved to <br />their existing state, have not been structurally designed, and have few if any, drainage facilities and <br />no curbs or gutters. Typically, an unimproved street must be fully improved through a local <br />improvement district, funded in part by the abutting property owners before a higher level of service <br />will be provided (see "City of Eugene Street Maintenance Policy and Procedure Manual" for levels of <br />maintenance service). Unimproved streets receive a low level of ongoing maintenance limited <br />primarily to emergency pothole patching (three inches or greater in depth) and minimal roadside <br />ditch maintenance. To address the growing number of potholes on City streets, the City Council <br />augmented the street repair budget with General Fund allocations for a total of $2.3 5 million from FY <br />2009 through FY 2011. Subsequently, Public Works has allocated $200,000 per year from Road Fund <br />for enhanced pavement repairs. The Maintenance Division has addressed potholes by either filling <br />individual potholes or by performing maintenance overlays over entire street segments. During the <br />past five years more than 75 unimproved streets, representing more than 23 lane miles, have been <br />resurfaced as a temporary treatment. In addition, several unimproved streets have been brought up to <br />full urban street standards through assessment projects, attributable in part to more flexible design <br />standards. <br />The following tables categorize Eugene's Improved and Unimproved Street System in Centerline <br />Miles and 12 -foot Lane Miles by Pavement Type and by Functional Class. <br />IMPROVED <br />SYSTEM <br />As halt ACP <br />Asphalt over <br />Concrete (APC ) <br />Concrete (PCC) <br />Gravel <br />Undeveloped <br />Total <br />Miles <br />12' Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' Lane <br />Miles <br />Major Arterial <br />13.12 <br />59.11 <br />0.03 <br />0.16 <br />1.38 <br />2.84 <br />0 <br />0 <br />0 <br />0 <br />14.53 <br />62.11 <br />Minor Arterial <br />60.61 <br />203.74 <br />2.23 <br />7.38 <br />3.73 <br />11.81 <br />0 <br />0 <br />0 <br />0 <br />66.57 <br />222.92 <br />Major Collector <br />30.18 <br />92.72 <br />1.16 <br />3.17 <br />2.88 <br />7.91 <br />0 <br />0 <br />0 <br />0 <br />34.22 <br />103.8 <br />Neighborhood <br />Collector <br />23.48 <br />60.91 <br />0.60 <br />1.62 <br />1.58 <br />4.35 <br />0 <br />0 <br />0 <br />0 <br />25.66 <br />66.88 <br />Residential <br />303.89 <br />705.97 <br />2.42 <br />6.19 <br />21.57 <br />54.86 <br />0 <br />0 <br />0 <br />0 <br />327.88 <br />767.02 <br />Total <br />431.28 <br />1122.45 <br />6.44 <br />18.52 <br />31.14 <br />81.77 <br />0 <br />0 <br />0 <br />0 <br />468.86 <br />1222.73 <br />UNIMPROVED <br />SYSTEM <br />As halt ACP <br />Bituminous <br />Surface BST <br />Concrete (PCC) <br />Gravel <br />Undeveloped <br />Total <br />Miles <br />12' Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' <br />Lane <br />Miles <br />Miles <br />12' Lane <br />Miles <br />Major Arterial <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />Minor Arterial <br />1.01 <br />1.96 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />1.01 <br />1.96 <br />Major Collector <br />2.74 <br />6.29 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />2.74 <br />6.29 <br />Neighborhood <br />Collector <br />4.36 <br />8.66 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />0 <br />4.36 <br />8.66 <br />Residential <br />38.88 <br />64.27 <br />3.95 <br />5.91 <br />0.03 <br />0.03 <br />8.73 <br />12.87 <br />4.46 <br />4.96 <br />56.05 <br />88.04 <br />Total <br />46.99 <br />81.18 <br />1 3.95 <br />1 5.91 <br />1 0.03 <br />1 0.03 <br />1 8.73 <br />1 12.87 <br />1 4.46 <br />4.96 <br />64.16 <br />1 104.95 <br />4 <br />
