An independent determination of impact fees may be made as follows:
(A) An applicant for development approval may elect to have an independent determination of the impact fees due for their development project in accordance with this section. Any applicant who makes this election shall prepare and submit to the impact fees administrator an independent fee study for the development project for which development approval is sought.
(B) All independent fee studies shall be prepared for review and submitted to the impact fees administrator no later than the time of application for a building permit. Any submission not so made shall be deemed waived.
(C) Each independent fee study shall comply in all respects with the requirements of this section and be organized in a manner that will allow the impact fees administrator to readily ascertain such compliance.
(D) Each independent fee study shall comply with all other written specifications as may be required by the impact fees administrator from time to time.
(E) The impact fees administrator shall determine the appropriate impact fees based on the results of the independent fee study and the applicable impact fee schedule established in § 14-19-13.
(F) Any impact fee calculated in accordance with this section and approved and certified in writing by the impact fees administrator shall be valid for four years following the certification. Following such period, a new application for an independent fee study must be made. Any change in the submitted development plan that in any material way affects said fee calculation shall void the certification of the fee.
(G) An independent fee determination study must address the expected impact of the development over the projected life of the structures on the system improvement. Any claim that the use or occupancy of the structures within the development will be different from normal use or occupancy must be supported by the appropriate zone change or other appropriate documentation that will support the claim.
