C. For uses that are not identified in the fees established by subsection (B) of this section, the city engineer shall calculate the impact fee amount using the methodology employed in the Transportation Impact Fee Rate Study Update.
D. For a substantial change in use of an existing building or dwelling unit, the impact fee shall be the applicable impact fee for the land use category of the new use, less the impact fee under the current rate schedule of the prior use.
E. The city engineer may in his/her sole discretion adjust the standard impact fee at the time the fee is imposed in consideration of unusual circumstances, in specific cases, to ensure that impact fees are imposed fairly.
F. Determinations made by the city engineer pursuant to this section may be appealed to the office of the hearing examiner as set forth in MMC 3.54.080.
G. The transportation impact fees computed in this section will be adjusted annually in accordance with a five-year rolling average of the Washington State Department of Transportation Construction Cost Index (“CCI”), coinciding with the city’s annual adoption of its six-year street plan.
H. Pursuant to and consistent with the requirements of RCW 82.02.060, impact fee schedules have been adjusted for future taxes and other revenue sources to be paid by the new development which are earmarked or proratable to the same new public facilities which will serve the new development.
