(b) When a county commission seeks to terminate any impact fee requirement, all unexpended funds shall be refunded to the owner or purchaser of the property from whom such fund was initially collected. Upon the finding that any or all fee requirements are to be terminated, the county commission shall place notice of such termination and the availability of refunds in a newspaper of general circulation one time a week for two consecutive weeks and shall also notify all known potential claimants by first class mail deposited with the United States postal service at their last known address. All funds available for refund shall be retained for a period of one year. At the end of one year, any remaining funds may be transferred to the general fund and used for any public purpose. A county commission is released from this notice requirement if there are no unexpended balances within an account or funds being terminated.
