Ohio Rev. Code § 5705.13
The ordinance or resolution establishing a reserve balance account shall state the purpose for which the account is established, the fund in which the account is to be established, and the total amount of money to be reserved in the account.
Not more than one reserve balance account may be established for each of the purposes permitted under divisions (A)(2) and (3) of this section. Money to the credit of a reserve balance account may be expended only for the purpose for which the account was established.
A reserve balance account established for the purpose described in division (A)(1) of this section may be established in the general fund or in one or more special funds for operating purposes of the subdivision. The amount of money to be reserved in such an account in any fiscal year shall not exceed five per cent of the revenue credited in the preceding fiscal year to the fund in which the account is established, or, in the case of a reserve balance account of a county or of a township, the greater of that amount or one-sixth of the expenditures during the preceding fiscal year from the fund in which the account is established. Subject to division (F) of section 5705.29 of the Revised Code, any reserve balance in an account established under division (A)(1) of this section shall not be considered part of the unencumbered balance or revenue of the subdivision under division (A) of section 5705.35 or division (A)(1) of section 5705.36 of the Revised Code.
At any time, a taxing authority of a subdivision, by resolution or ordinance, may reduce or eliminate the reserve balance in a reserve balance account established for the purpose described in division (A)(1) of this section.
A reserve balance account established for the purpose described in division (A)(2) or (3) of this section shall be established in the general fund of the subdivision or by the establishment of a separate internal service fund established to account for the operation of an individual or joint self-insurance program described in division (A)(2) of this section or a workers' compensation program or plan described in division (A)(3) of this section, and shall be based on sound actuarial principles. The total amount of money in a reserve balance account for self-insurance may be expressed in dollars or as the amount determined to represent an adequate reserve according to sound actuarial principles.
A taxing authority of a subdivision, by resolution or ordinance, may rescind a reserve balance account established under this division. If a reserve balance account is rescinded, money that has accumulated in the account shall be transferred to the fund or funds from which the money originally was transferred.
A taxing authority of a subdivision shall not accumulate money in a capital projects fund for more than ten years after the resolution or ordinance establishing the fund is adopted. If the subdivision has not entered into a contract for the acquisition, construction, or improvement of fixed assets for which money was accumulated in such a fund before the end of that ten-year period, the fiscal officer of the subdivision shall transfer all money in the fund to the fund or funds from which that money originally was transferred or the fund that originally was intended to receive the money.
A taxing authority of a subdivision, by resolution or ordinance, may rescind a capital projects fund. If a capital projects fund is rescinded, money that has accumulated in the fund shall be transferred to the fund or funds from which the money originally was transferred.
Notwithstanding sections 5705.14, 5705.15, and 5705.16 of the Revised Code, the taxing authority of a subdivision, by resolution or ordinance, may transfer money to the capital projects fund from any other fund of the subdivision that may lawfully be used for the purpose of acquiring, constructing, or improving the fixed assets identified in the resolution or ordinance.
