Ohio Revised Code Title III. Counties § 349.05

A new community authority established pursuant to this chapter is a body corporate and politic, and shall have the powers specifically granted by this chapter. This chapter does not limit or restrict the power and authority of cities, counties, and townships. The new community authority shall have no power or authority over zoning or subdivision regulation, provision of fire or police protection, or, unless such services cannot be obtained from other existing political subdivisions, water supply or sewage treatment and disposal.

The exercise of police power granted to the authority by this chapter does not invalidate the exercise of police power by any municipal corporation and the exercise of police power by a municipal corporation shall prevail in the case of a conflict with powers exercised by the authority. The grant of power to the authority under divisions (N) and (O) of section 349.06 of the Revised Code shall not remove municipal, regional, or county planning commissions and agencies from jurisdiction within the district, nor shall such powers invalidate municipal ordinances and resolutions or other regulations of such planning commission and agencies.
