EUGENE’S STREET INVENTORY <br />The City of Eugene has jurisdictional responsibility for many different types and <br />classifications of roads within the transportation system. Many factors such as age, <br />development type, traffic loads, use, and future transportation needs affect the maintenance <br />and rehabilitation planning for the system. The segment inventory component of the PMS <br />system allows a reporting of both centerline miles (intersection to intersection) and lane miles <br />of each segment of the system. While commonly used in reporting distance, centerline miles <br />do not relate equally across streets of different widths or different number of lanes. For this <br />report, comparisons typically are shown both in centerline and 12 foot wide lane miles unless <br />otherwise noted. <br />Improvement Status <br />For purposes of establishing budget allocations and rehabilitation priorities, and performing <br />maintenance activities based on established maintenance policies, Eugene divides the street <br />inventory into two distinct categories: <br />Improved streets are those which have been fully designed for structural adequacy, have <br />storm drainage facilities provided which include curbs and gutters, and have either an asphalt <br />concrete (AC) or a portland cement concrete (PCC) surface. Typically, these streets were <br />either fully improved when the area was developed and paid for by the developer, or were <br />improved through a local improvement district (LID) and paid for in part by the abutting <br />property owners. In some cases a street may have been fully improved while under State or <br />County jurisdiction and then surrendered to the City. Improved streets receive the highest <br />level of ongoing maintenance and are eligible for rehabilitation funding through Eugene's <br />Capital Improvement Program (CIP) and Pavement Preservation Program (PPP). <br />Unimproved streets are those with soil, gravel, or asphalt mat surfaces which have typically <br />evolved to their existing state, have not been structurally designed, have few drainage <br />facilities, and no curbs and gutters. Unimproved streets receive a low level of ongoing <br />maintenance limited primarily to emergency pothole patching and minimal roadside ditch <br />maintenance. Unimproved Streets are not considered eligible for funding in Eugene's Capital <br />Improvement Program or the Pavement Preservation Program. Typically, an unimproved <br />street must be fully improved through a local improvement district, funded in part by the <br />abutting property owners before a higher level of service will be provided (see “City of <br />Eugene Street Maintenance Policy and Procedure Manual” for levels of maintenance service). <br />3 <br />
