The levy of any excise, income, or property tax by the state or by any political subdivision thereof shall not be construed as preempting the power of a county or transit authority to levy an additional use tax pursuant to section 5741.021, 5741.022, or 5741.023 of the Revised Code. No tax levied by a board of county commissioners pursuant to section 5741.022 of the Revised Code shall become effective at any time while a tax levied by the board of trustees of a regional transit authority pursuant to such section is in effect in any part of such county.
