METHODOLOGY: <br /> City of Eugene Systems Development Charges <br /> ! Appendix B <br /> Transportation System Charge Detail <br /> 10 Arterial~!,and Collector Streets <br /> i <br /> 1.1 Fgrmula <br /> The arterial and collector street component is based upon the cost of increasing the vehicular <br /> capacity of these streets. Each lane is calculated to provide a certain capacity. Level-of- <br /> service 'D', the standard adopted in TransPlan (Eugene-Springfield Metropolitan Area <br /> Taanspgrtation Plan), the area's long-range transportation plan, is used as the basis for the <br /> calculaf~pn. The cost of increasing capacity is based on the average cost paid by the City for <br /> each lathe mile of arterial and collector streets. Note that the cost calculation excluded the <br /> assessable costs and evaluated only the arterial and collector system. Paragraph 1.3 and <br /> Table 3of this Appendix contains a detailed analysis and numerical supporting data of the <br /> costs u$ed for the arterial and collector component computations. <br /> The impact of new development on the street network is determined by the following Impact <br /> Fee formula: <br /> (Miles per trip) <br /> . <br /> Typical Total Street.;.. <br /> _ TwYps Units X.` System.. <br /> Generated X per X Cost per <br /> per Unit Development < Lane Mde ` <br /> i Street System Capacity perl.ane Mife <br /> Where; <br /> Impact, Fee =The transportation SDC fee to be collected from a development which <br /> represents its equitable share contribution to the public street system. The transportation <br /> SDC isi calculated by multiplying the cost per trip (indicated by the gray shaded areas) by the <br /> units in a development, multiplied by the average trips generated for similar types of <br /> development. <br /> Trips ~ A single or one-direction vehicle movement with either the origin or the destination <br /> (exiting or entering) inside a study site. <br /> Typical Trips Generated per Unit =The number of vehicle trips caused by the development <br /> during'Ithe hours of peak afternoon traffic (P.M. peak hours). The P.M. peak hour trip rate <br /> varies according to land use. Transportation facilities must be built to accommodate the peak <br /> demand, thus the use of the P.M. peak hour trip generation rate. Trip rates are to be <br /> determined using paragraph 3.0, Trip Generation Rates, of this Appendix B. <br /> City of Eugene SDC Methodology Transportation, Pagel3-1 <br /> <br /> it <br /> <br />
