But in all such cases the required permits must be obtained within three (3) business days and any unreasonable delay in obtaining those permit(s) shall result in the charge of a double fee. The payment of a double fee shall not preclude or be deemed a substitute for prosecution for commencing work without first obtaining a permit.
