METHODOLOGY: City of Eugene Systems Development Charges Appendix B Transportation System Charge Detail 1.0 Transportation sDC Methodology The transportation SDC methodology is based on a level of service (LOS) approach, and consists of a street component and an off-street bicycle path component. The street component is a combination of improvement and reimbursement fees. Development of the SDC under the LOS methodology includes the following basic steps: · Determine SDC cost basis · Define system capacity · Calculate the unit cost of capacity · 'Develop SDC rate schedule These steps are discussed below for the street and bicycle components. Related information is displayed in Figures 2 and 3. 1.1 Street Component 1.1.1 Formula The street component is determined based on the average cost per lane mile of the arterial and collector street system and the estimated lane miles required by an average trip, given a specified level of service. The SDC calculation under a LOS approach is represented by the following formulas Cost per Trip (street) = A verage Cost Per Lane Mile of Street System X Average Lane Miles Per Trip 1.1.2 Step 1 - Determine sDC Cost Basis The cost basis is the average cost of constructing a lane mile in the arterial and collector street system. The average cost per lane mile is based on a Replacement Cost New valuation, whereby all facilities are valued in terms of current year dollars, thus capturing any inflationary impacts, as well as changes in market conditions since original construction of assets. In calculating the average cost per lane mile in the transportation system, the following cost components are considered: · Collector and Arterial Streets > Non-assessable Linear Construction Costs > I ntersection Construction Costs > Traffic Signal Costs City of Eugene sDC Methodology Transportation, Page B- 1
