A. The following shall be exempted from payment of the impact fee:
1. Alterations or expansion of an existing building where no additional units are created, where the use is not changed, and where no additional vehicular trips will be produced over and above those produced by the existing use.
2. The construction of accessory buildings or structures that will not produce additional vehicular trips over and above those produced by the principal building or use of the land.
3. The replacement of a destroyed or partially destroyed building or structure with a new building or structure of the same size and use provided that no additional trips will be produced over and above those produced by the original use of the land.
4. The installation of a replacement mobile home on a lot or other such site when a transportation impact fee for such mobile home site has previously been paid pursuant to this chapter or where a mobile home legally existed on such site on or prior to the effective date of this chapter.
5. Any claim of exemption must be made in writing and agreed to by the city prior to the issuance of the applicable building permit or permit for mobile home installation. Any claim not so made shall be deemed waived.
B. Where a fee is otherwise payable pursuant to this chapter, a feepayer may apply for a reduction of the fee to recognize an existing or previous use on the subject real property. A reduction for existing or previous use shall be provided where an existing structure or structures with clearly established uses will be demolished in conjunction with a land development project, or a structure or structures have been demolished on the subject property within twenty (20) years of a land development project and where there is clear documentation of the previous existence and use. No reduction pursuant to this subsection shall result in a reduction of the fee to less than zero. No reduction pursuant to this subsection may be transferable to other projects on other properties. The feepayer is responsible for submitting all documentation required by the city for consideration of an existing or previous use fee reduction. Any request for an existing or previous use reduction must be made in writing and the amount determined by the city prior to the issuance of the applicable building permit or permit for mobile home installation. The amount of reduction shall be determined by the city engineer and shall be based on the amount fee that would be payable by the previous use with reference to the fee schedule in existence at the time of the new building permit.
