METHODOLOGY: <br /> City of Eugene Systems Development Charges <br /> Appendix B <br /> Transportation System Charge Detail <br /> <br /> 1.0 q#t~rial and Collector Streets <br /> 1.1 Formula <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 /> Transportation Plan), the area's long-range transportation plan, is used as the basis for the <br /> calculation. The cost of increasing capacity is based on the average cost paid by the City for <br /> each lane 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 3 of this Appendix contains a detailed analysis and numerical supporting data of the <br /> costs used 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 /> I _ <br /> f I~ `I~II~I ~ ~ ~~~r~lil~~i~~~~~~iY l~fi"rl ~il.+i "~I~ <br /> &&& Total Street <br /> T ical <br /> p <br /> Y <br /> Units <br /> p System <br /> _ Tn s X per X X '.Cost per <br /> Generated Development "Lane Mile <br /> per Unit <br /> Street System Capacity per Lane Mile' <br /> Where: <br /> I_ act Fee =The transportation SDC fee to be collected from a development which <br /> f~resents its equitable share contribution to the public street system. The transportation - <br /> SDC is 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 the 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, PageB-1 <br /> <br />
