21.18.040   Findings, impact fees imposed on a specific development project.
   Before imposing payment of any impact fee as a condition of approval for any development project, the approving body shall determine how there is a reasonable relationship between the amount of the fee and the cost, or portion of the cost, of the public facility or other public expenditure attributable to the development project on which the fee is imposed. These findings shall be supported by substantial evidence.
