A. Unless otherwise exempted by the provisions of this chapter or other local or state law, a system development charge is hereby imposed upon all development within the city, upon the act of making a connection to the city water or sewer system within the city, and upon all development outside the boundary of the city that connects to or otherwise uses the sewer facilities, storm drainage system, or water system, transportation system or park and recreation systems of the city.

B. Systems development charges for each type of capital improvement may be created through applications of the methodologies described in TMC 13.35.050. The amounts of each system development charge shall be adopted initially by council under separate ordinance.

A change in the amount of a reimbursement fee or an improvement fee is not a modification of the system development charge if the change in amount is based on the periodic application of an adopted specific cost index or a modification to any of the factors related to the rate that are incorporated in the established methodology. Changes in the amounts shall also be adopted by separate ordinance, excepting those changes resulting solely from inflationary cost impacts. Inflationary cost impacts shall be measured and calculated each March 1st by the city manager and approved by the city council. Such calculations will be based upon Pacific Northwest construction cost changes in the Engineering News-Record Construction Cost Index (ENR Index). All calculations shall be carried out to the hundredths place. A final product ending in $0.49 or less shall be rounded down to the nearest dollar, $0.50 or more up to the next dollar.
