(A) Applications for a hearing before the Planning and Zoning Commission for variances to the provisions of this subchapter shall be submitted to the Planning Department.
(B) The Planning and Zoning Commission may consult with representatives from the County SWCD; the Ohio Department of Natural Resources, Division of Natural Areas; the Ohio Environmental Protection Agency, Division of Surface Water; the County Engineer; the Department of Environmental Services of the county; the County Health Department; or other technical experts as necessary to provide the necessary data for the Planning and Zoning Commission to consider variance requests.
(C) Expansions of residential structures or uses exceeding 15% of the footprint area and expansions of all nonresidential structures or uses are subject to the following:
(1) The expansion conforms to the existing zoning regulations;
(2) The expansion must not impact the stream channel or the 100-year floodplain;
(3) The expansion of a nonresidential structure or use must not affect upstream or downstream hydrologic conditions which could cause damage from flooding or stream bank erosion to landowners in those areas. A hydrologic study must be completed by nonresidential applicants only as a process of the variance application; and
(4) The expansion of a nonresidential structure or use will not exceed 25% of the footprint area. The 25% expansion limit is per the portion of the structure or use that lies within the riparian setback.
(D) Requests for variances for subdivisions will be considered for the following:

(2) A reduction of the setback width, not to exceed 10% of the prescribed riparian setback width.
(E) No variances shall be granted for expansion of the following structures or uses:
(1) Facilities which use, store, distribute or sell petroleum-based products or any hazardous materials. Such facilities include, but are not limited to, asphalt plants, dry cleaners, gasoline service stations and road maintenance facilities; or
(2) Facilities which use, store, distribute or sell products which may contribute higher than acceptable concentrations of dissolved or particulate matter to storm water runoff around the facility. Such facilities include, but are not limited to, landfills or transfer stations, junk yards, recycling facilities, quarries and borrow pits, sand and gravel extraction operations, and road salt storage barns.
(F) In reviewing whether to grant variances, the Planning and Zoning Commission shall consider the following:
(1) The extent to which the requested variance impairs the functions of the riparian area. This determination shall be based on sufficient technical and scientific evidence as provided by the applicant and the agencies listed in divisions (A) through (E) of this section;
(2) The soil type and natural vegetation of the parcel, as well as the percentage of the parcel that is in the 100-year floodplain; and
