If a building permit or permit for mobile home installation expires without commencement of construction, then the feepayer shall be entitled to a refund, without interest, of the impact fee paid as a condition of its issuance; except, that the city shall retain five percent of the fee to offset a portion of the costs of collection and refund. The feepayer must submit an application for such refund to the city engineer within thirty (30) days of the expiration of the permit. (Ord. 2017-01 (part), 2017: Ord. 2008-14, 2008: prior code § 9520)
