Ohio Rev. Code § 6101.68
The same land, if conducive to public health, safety, convenience, or welfare, may be included in more than one conservancy district and be subject to this chapter for each district in which it may be included. No district shall be organized under this chapter in whole or in part within the territory of a district already organized under this chapter until the court determines whether the public health, safety, convenience, or welfare demand the organization of an additional district, or whether it demands that the territory proposed to be organized into an additional district shall be added to the existing district. If the proceedings concerning two or more districts are before the court of common pleas of two or more counties, that determination shall be as provided in section 6101.69 of the Revised Code.
