A. Unless otherwise exempted by the provisions of this chapter or other local or state law, a systems development charge is imposed upon all new development within the city for transportation, parks and all new development inside and outside the boundary of the city that connects to or otherwise uses the sanitary sewer system or storm drainage system of the city. The city manager is authorized to make interpretations of this section, subject to appeal to the city council.

B. Systems development charges for each type of capital improvement may be created through application of the methodologies described in MMC 3.10.030. The amounts of each systems development charge shall be adopted initially by council resolution. Changes in the amounts shall also be adopted by resolution, except changes resulting solely from inflationary cost impacts. Inflationary cost impacts shall be measured and calculated each January by the city engineer and charged accordingly. Such calculations will be based upon changes in the engineering News Record Construction Index (ENR Index) for Seattle, Washington. (Ord. 4980 §1, 2014; Ord. 4585 §1c, 1995; Ord. 4495 §1 (part), 1991).
