=The factor used to account for the fact that each trip has an origin and a destination. By <br />applying this factor, costs are equally assigned between the origin and the destination (trip <br />ends) and each development should be responsible for only half of the total impact of each <br />trip. <br />Average Length of Metro. Trips =The average length of all vehicle trips for the local <br />Springfield-Eugene metropolitan area. The current average length of vehicle trips can be <br />found in Table 3. <br />Eugene Trip End P. M. Peak Vehicle Miles; Percent on Eugene's Arterials and Collector <br />Streets =The portion of the length of all vehicle trips with at least one end point in Eugene <br />that occur on Eugene arterials and collector streets. The percentage does not include travel <br />in Eugene that occurs on state highways, county roads, or local streets. Analysis of traffic <br />flow is used to determine the percent of P.M. peak vehicle miles traveled on trips originating <br />andior ending in the Eugene Urban Growth Boundary, that occurs on Eugene's arterial and <br />collector streets -- the streets that are eligible for cost recovery through SDCs. State <br />highways and county roads are excluded from this analysis since the City of Eugene is not <br />responsible for construction costs associated with those facilities. Local streets. are excluded <br />from the SDC analysis since they are funded through assessment revenues. <br />Trip End =One trip end is equal to one trip, as defined above. For trip generation purposes, <br />total trip ends for a land use over a given period of time are the total of all trips entering plus <br />all trips exiting a site during that period. <br />Miles per Trip =Eugene's average one way trip length for arterials and collectors, <br />represented by the numerator in the above equation (darker gray shaded area), is the <br />percentage of Eugene traffic eligible for recovery through SDCs. <br />Street System Capacity per Lane Mile =The capacity of a lane at level of service (LOS) "D". <br />Because of the limitations imposed at intersections, the capacity of a lane at LOS "D" is 675 <br />vehicles per lane, per hour. The LOS "D" refers to a range of volume to capacity ratios in <br />which acceptable traffic flows are anticipated. For purposes of identifying future traffic <br />overloads, streets and highway are considered to have inadequate capacity with level "E" or <br />"F" load. LOS "D" was established based on several components and is the minimal level of <br />service established in the City's infrastructure plans (e.g. Transplan) for transportation and <br />is also the national standard that urban arterial and collector streets are typically designed <br />to meet. <br />Total Street System Cost per Lane Mile =The average cost of right-of-way acquisition and <br />construction for one lane mile of street. This figure includes the cost for construction of <br />streets, intersections, necessary structures (e.g., bridges), and traffic signals. <br />1.2 Application <br />The development charge is based upon traffic generated by each development during the <br />peak hour times the cost per trip. All development shall pay based upon the number of p.m. <br />peak hour trips generated. <br />A basic assumption of the transportation SDC is that development will generate the need for <br />capital improvements directly related to its size as measured for its classified use. The size <br />of a development is measured in the units identified in subparagraph 3.1.2 of this Appendix <br />for the development's classification as determined by the City's Traffic Engineer. <br />City of Eugene SDC Methodology Transportation, Page B- 2 <br />
