A. The planning standard for transportation capacity shall be level of service “D” as defined in the Highway Capacity Manual, as determined from time to time by council resolution.

B. The value of existing facilities shall be determined on the basis of city and county records. The cost of existing facilities for reimbursement shall not include the amount which was assessed by the city under local improvement districts.

C. The projected cost of future capacity-increasing transportation facilities shall be determined on the basis of the capital improvements plan or facilities plans adopted by the city council.

D. To determine the improvement fee, the costs of future transportation facilities shall be divided by the number of peak-hour trips for which the transportation system provides service to determine a charge on a dollar per peak-hour trips. This figure represents an average cost of transportation capacity development to serve new construction. The charge for future facilities shall be designated as an improvement fee.

E. The costs of compliance with Oregon law in the determination of SDCs shall include the estimated cost of landscape architecture, engineering, legal, planning, administrative and accounting services. Compliance costs per peak-hour trip shall be determined on the basis of projected traffic growth. The compliance costs shall be designated a reimbursement fee.

F. The calculations shall be done on a citywide basis so that the charge reflects the average cost per peak-hour trip throughout the city. The established charge per trip shall not exceed the sum of the reimbursement fee and the improvement fee including compliance costs.

G. The number of peak-hour trips generated for various land uses shall be determined based upon the Institute of Transportation Engineers Trip Generation Manual (Ninth Edition).

H. The charge for each building permit shall be the number of units to be constructed times the calculated charge per-peak hour trip. [Ord. 904 Art. 3, 2015; Ord. 790 Art. 3; Ord. 728 Art. 3.]
