Height restrictions shall be considered adequate if as a minimum they meet the obstruction standards of subchapter C of Part 77 of the Federal Aviation Regulations of the Federal Aviation Administration, as these standards apply to civil airport imaginary surfaces related to runways.
The airport-owning entity shall have sufficient control over obstructions in the airspace in the vicinity of the airport to assure that height restrictions can be maintained. This control may be in the form of ownership of any land from which obstructions may rise, air navigation easements to guarantee maintenance of restrictions, or height limitation or land use zoning which will prohibit obstructions which would violate the obstruction standards.
