1. (1) To provide additional revenues for the payment of bonds or notes issued in anticipation of bonds issued by a convention facilities authority established by the board of county commissioners under Chapter 351. of the Revised Code and to provide additional operating revenues for the convention facilities authority;

The rate of tax shall be a multiple of one-twentieth of one per cent, unless a portion of the rate of an existing tax levied under section 5739.023 of the Revised Code has been reduced, and the rate of tax levied under this section has been increased, pursuant to section 5739.028 of the Revised Code, in which case the aggregate of the rates of tax levied under this section and section 5739.023 of the Revised Code shall be a multiple of one-twentieth of one per cent.

The board shall deliver a certified copy of the resolution to the tax commissioner, not later than the sixty-fifth day prior to the date on which the tax is to become effective, which shall be the first day of a calendar quarter. Prior to the adoption of any resolution to levy the tax or to increase the rate of tax exclusively for the purpose set forth in division (A)(3) of this section, the board of county commissioners shall conduct two public hearings on the resolution, the second hearing to be no fewer than three nor more than ten days after the first. Notice of the date, time, and place of the hearings shall be given by publication in a newspaper of general circulation in the county, or as provided in section 7.16 of the Revised Code, once a week on the same day of the week for two consecutive weeks. The second publication shall be no fewer than ten nor more than thirty days prior to the first hearing. Except as provided in division (E) of this section, the resolution shall be subject to a referendum as provided in sections 305.31 to 305.41 of the Revised Code. If the resolution is adopted as an emergency measure necessary for the immediate preservation of the public peace, health, or safety, it must receive an affirmative vote of all of the members of the board of county commissioners and shall state the reasons for the necessity. If the tax is for more than one of the purposes set forth in divisions (A)(1) to (7), (9), (10), and (12) of this section, or is exclusively for one of the purposes set forth in division (A)(1), (2), (4), (5), (6), (7), (9), (10), or (12) of this section, the resolution shall not go into effect unless it is approved by a majority of the electors voting on the question of the tax.

(C)

1. (1) If the tax is to be used for more than one of the purposes set forth in divisions (A)(1) to (7), (9), (10), and (12) of this section, the board of county commissioners shall establish the method that will be used to determine the amount or proportion of the tax revenue received by the county during each year that will be distributed for each of those purposes, including, if applicable, provisions governing the reallocation of a convention facilities authority's allocation if the authority is dissolved while the tax is in effect. The allocation method may provide that different proportions or amounts of the tax shall be distributed among the purposes in different years, but it shall clearly describe the method that will be used for each year. Except as otherwise provided in division (C)(2) of this section, the allocation method established by the board is not subject to amendment during the life of the tax.

2. (2) Subsequent to holding a public hearing on the proposed amendment, the board of county commissioners may amend the allocation method established under division (C)(1) of this section for any year, if the amendment is approved by the governing board of each entity whose allocation for the year would be reduced by the proposed amendment. In the case of a tax that is levied for a continuing period of time, the board may not so amend the allocation method for any year before the sixth year that the tax is in effect.

   1. (a) If the additional revenues provided to the convention facilities authority are pledged by the authority for the payment of convention facilities authority revenue bonds for as long as such bonds are outstanding, no reduction of the authority's allocation of the tax shall be made for any year except to the extent that the reduced authority allocation, when combined with the authority's other revenues pledged for that purpose, is sufficient to meet the debt service requirements for that year on such bonds.
   2. (b) If the additional revenues provided to the county are pledged by the county for the payment of bonds or notes described in division (A)(4) or (5) of this section, for as long as such bonds or notes are outstanding, no reduction of the county's or the community improvements board's allocation of the tax shall be made for any year, except to the extent that the reduced county or community improvements board allocation is sufficient to meet the debt service requirements for that year on such bonds or notes.
   3. (c) If the additional revenues provided to the transit authority are pledged by the authority for the payment of revenue bonds issued under section 306.37 of the Revised Code, for as long as such bonds are outstanding, no reduction of the authority's allocation of tax shall be made for any year, except to the extent that the authority's reduced allocation, when combined with the authority's other revenues pledged for that purpose, is sufficient to meet the debt service requirements for that year on such bonds.
   4. (d) If the additional revenues provided to the county are pledged by the county for the payment of bonds or notes issued under section 133.60 of the Revised Code, for so long as the bonds or notes are outstanding, no reduction of the county's allocation of the tax shall be made for any year, except to the extent that the reduced county allocation is sufficient to meet the debt service requirements for that year on the bonds or notes.

(D)

1. (1) The resolution levying the tax or increasing the rate of tax shall state the rate of the tax or the rate of the increase; the purpose or purposes for which it is to be levied; the number of years for which it is to be levied or that it is for a continuing period of time; the allocation method required by division (C) of this section; and if required to be submitted to the electors of the county under division (A) of this section, the date of the election at which the proposal shall be submitted to the electors of the county, which shall be not less than ninety days after the certification of a copy of the resolution to the board of elections and, if the tax is to be levied exclusively for the purpose set forth in division (A)(3) of this section, shall not occur in August of any year. Upon certification of the resolution to the board of elections, the board of county commissioners shall notify the tax commissioner in writing of the levy question to be submitted to the electors. If approved by a majority of the electors, the tax shall become effective on the first day of a calendar quarter next following the sixty-fifth day following the date the board of county commissioners and tax commissioner receive from the board of elections the certification of the results of the election, except as provided in division (E) of this section.

2. (2)

   1. (a) A resolution specifying that the tax is to be used exclusively for the purpose set forth in division (A)(3) of this section that is not adopted as an emergency measure may direct the board of elections to submit the question of levying the tax or increasing the rate of the tax to the electors of the county at a special election held on the date specified by the board of county commissioners in the resolution, provided that the election occurs not less than ninety days after the resolution is certified to the board of elections and the election is not held in August of any year. Upon certification of the resolution to the board of elections, the board of county commissioners shall notify the tax commissioner in writing of the levy question to be submitted to the electors. No resolution adopted under division (D)(2)(a) of this section shall go into effect unless approved by a majority of those voting upon it and, except as provided in division (E) of this section, not until the first day of a calendar quarter following the expiration of sixty-five days from the date the tax commissioner receives notice from the board of elections of the affirmative vote.
   2. (b) A resolution specifying that the tax is to be used exclusively for the purpose set forth in division (A)(3) of this section that is adopted as an emergency measure shall become effective as provided in division (A) of this section, but may direct the board of elections to submit the question of repealing the tax or increase in the rate of the tax to the electors of the county at the next general election in the county occurring not less than ninety days after the resolution is certified to the board of elections. Upon certification of the resolution to the board of elections, the board of county commissioners shall notify the tax commissioner in writing of the levy question to be submitted to the electors. The ballot question shall be the same as that prescribed in section 5739.022 of the Revised Code. The board of elections shall notify the board of county commissioners and the tax commissioner of the result of the election immediately after the result has been declared. If a majority of the qualified electors voting on the question of repealing the tax or increase in the rate of the tax vote for repeal of the tax or repeal of the increase, the board of county commissioners, on the first day of a calendar quarter following the expiration of sixty-five days after the date the board and tax commissioner received notice of the result of the election, shall, in the case of a repeal of the tax, cease to levy the tax, or, in the case of a repeal of an increase in the rate of the tax, cease to levy the increased rate and levy the tax at the rate at which it was imposed immediately prior to the increase in rate.
   3. (c) A board of county commissioners, by resolution, may reduce the rate of a tax levied exclusively for the purpose set forth in division (A)(3) of this section to a lower rate authorized by this section. Any such reduction shall be made effective on the first day of the calendar quarter next following the sixty-fifth day after the tax commissioner receives a certified copy of the resolution from the board.
