1.3.5 Arterial and Collector Street Lighting <br />The arterial and collector street lighting component is also based on a per lane mile <br />level of service. The arterial and collector street lighting component is calculated from <br />the ratio of arterial and collector street lights to arterial and collector lane miles, which <br />yields a level of service of street lighting per lane mile (standard). The cost to construct <br />a street light is multiplied by the standard and added to the total cost per lane mile for <br />the Transportation SDC. The impact formula for new development on the street lighting <br />network is: <br />Typical Units <br />Trips <br />Generated X per <br />per Unit Development <br />1.3.6 Summary of Costs <br />To summarize, the total cost for arterial and collector streets, the total cost per lane <br />mile, includes the cost for street lighting plus the combined cost per lane mile of linear <br />section streets, intersections, traffic signals, bridges and other structures. Refer to <br />Table 3 for specific data on the transportation costs. <br />2.0 Off-Street Bicycle Paths <br />The off-street bicycle path component of the transportation charge is based on maintaining an <br />existing standard number of miles of path per thousand persons. The cost per mile of off-street <br />bicycle path is added to the cost per mile for off-street bicycle path lighting and the total is divided by <br />the population to derive a per person cost. To convert this to a p.m. peak trip rate, the cost per <br />person is divided by the trips per person, to yield the cost per trip. Figure 3 illustrates the method <br />used to calculate the off-street bicycle path component of the transportation SDC. <br />3.0 Trip Generation Rates <br />Y' <br />'"x' <br />The transportation SDC may be calculated using trip ;generation rates established according to this <br />paragraph. There are two methods of calculation: the Standard Calculation or the Alternate <br />Calculation. <br />3 .1 Standard Calculation <br />3.1.1 Assigned Trip Rate <br />Except when the City Traffic Engineer has approved an applicant's election to use the <br />Alternate Calculation method the City Trafi•ic Engineer shall assign the trip rate to the <br />proposed development using the classifications in 3.1.2 below. <br />City of Eugene SDC Methodology ~ Transportation, PageB-7 <br />
