Ohio Rev. Code § 323.07
The county treasurer may accept special assessment bonds as provided in section 323.06 of the Revised Code when offered in an amount equal or greater than the amount of the assessment owing, in full payment of such special assessment. The treasurer shall not refund in cash or in any other form to the special assessment taxpayer the difference between the value of the bonds offered and the amount of the special assessment for which payment is made, but a group of special assessment taxpayers may purchase one or more bonds and the treasurer shall accept them in payment of the special assessments owing in such instance.
The treasurer, at the time for distributing special assessment taxes, shall distribute to the proper subdivision the bonds received by the treasurer under this section and section 323.06 of the Revised Code. The distribution so made shall be a full or partial discharge of the special assessment taxes.
