Sec. 20. In order to provide free air space for the safe descent, landing and ascent of aircraft and for the proper and safe use of any airport or landing field acquired or maintained under this chapter, the department is hereby given the right, powers and authority to establish and fix by ordinance or ordinances a restricted zone or zones for such distance in any direction from the boundaries of such airport or landing field, within which zone or zones so established, as in the opinion of the department is necessary and practicable, no building or other structure shall be erected high enough to interfere with the descent of an aircraft at such approach angle as may be deemed reasonably necessary for the safety for the type of operation that is, or is anticipated to be, conducted at such landing field; however, the department may by ordinance, establish standards regulating, within said zone or zones, the emission of air pollutants such as, but not limited to, smoke, dust, noxious fumes, glare and electrical radiation which would compromise the safety of aircraft by interfering with visability, operation of electrical equipment or any other condition necessary for safe flight.
