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. Unimproved streets receive a low level of on-going maintenance <br />limited primarily to pothole patching and roadside ditch maintenance. Unimproved Streets <br />are not considered eligible for funding in Eugene's Capital Improvement program. <br />Typically, an unimproved street must be fully improved through a local improvement <br />district, funded in part by the abutting property owners before a higher level of service will be <br />provided. <br />FUNCTIONAL CLASSIFICATIONS <br />The quantity and associated vehicle weight of traffic using streets is a critical factor affecting the rate <br />at which a pavement and roadbed deteriorates. Eugene divides its streets into five categories called <br />functional classifications (FC) each representing a different volume and type of vehicular usage. <br />MAJOR ARTERIAL (FC-1) -Major Arterials are usually four or more lanes, generally <br />connect various parts of the region with one another within the city and with the "outside <br />world". They serve as major access routes to regional destinations such as downtowns, <br />universities, airports, and similar major focal points within the urban area. Major Arterials <br />typically carry an average of more than 20,000 vehicles per day. Major Arterials receive <br />- high priority maintenance. <br />MINOR ARTERIAL (FC 2) -Minor Arterials are typically two or three lanes. These streets <br />provide the next level of urban connectivity below major arterials. Inmost cases their main <br />role tends to be serving infra-city mobility. Minor Arterials carry between 7,500 and 20,000 <br />vehicles per day. Minor arterials receive priority maintenance. <br />MAJOR COLLECTOR (FC-3) -Major Collectors can be found in residential, commercial <br />and industrial areas. They typically carry between 2,500 and 7,500 vehicles per day. Major <br />Collectors have a higher priority for maintenance than local streets. <br />NEIGHBORHOOD COLLECTOR (FC-4) Neighborhood Collectors are found only in <br />residential neighborhoods and provide a high degree of access to individual properties in a <br />neighborhood. They typically carry between 1,500 to 2,500 vehicles per day. Prior to the <br />adoption of the Eugene Arterial & Collector Street Plan in November 1999, this functional <br />classification designation did not exist, subsequently these streets were generally designated <br />as collector. <br />~_~ <br />Page 2 <br />
