The Union County Engineer administers the Airport Zoning Regulations as adopted by the Union County Commissioners to ensure the safety of aircraft flying in the vicinity of the Union County Airport. The Airspace Zoning Map shows the areas or zones around the airport that are subject to these regulations.
In addition to the local permit, the applicant must also obtain permits from the FAA and ODOT Division of Aviation as explained in this memo from the Ohio Board of Building Standards.
Applicants are also recommended to review their plans with the Union County Airport Authority to see if other site considerations are a safety concern. For example, a stormwater pond could attract geese and cause a bird strike hazard.
A general rule of thumb would be that an Airport Zoning Permit may be required for structures that are 75 feet or greater in height in the horizontal or conical zones and 50 feet or greater if located in the approach zone. This includes temporary cranes that may be used during construction. The Union County Building Department can determine if an Airport Zoning Permit is needed.
With your permit application, you need to include a site plan showing the proposed structures, top of building elevations and USGS elevations for the site. You also need to include information related to cranes or any water features, such as stormwater ponds, that will be part of the site development.
The cost for the Union County Airport Zoning Permit is $50, checks payable to Union County Building Department.
