As used in this section, unless the context otherwise requires:


“Height” means the distance from the original grade at the base of a tower to the highest point of the tower.


“Tower” means a structure that is either self-standing or supported by guy wires and ground anchors, is smaller than six feet in diameter at the base, and has accessory facilities on which an antenna, sensor, camera, meteorological instrument, or other equipment is mounted. “Tower” does not include a structure that is located adjacent to a building, house, barn, or electric utility substation or in the curtilage of a farmstead.


Where the appearance of a tower is not otherwise governed by state or federal law, rule, or regulation, any tower over fifty feet in height that is located outside the boundaries of an incorporated city or town on land that is primarily rural or undeveloped or used for agricultural purposes must be marked and painted or otherwise constructed to be visible in clear air during daylight hours from a distance of not less than two thousand feet. Towers must also comply with the following additional requirements:


A tower must be painted in equal alternating bands of aviation orange and white, beginning with orange at the top of the tower;


One marker ball must be attached to the top third of each outside guy wire; and


Guy wires must have a seven-foot-long safety sleeve at each anchor point that extends from the anchor point along each guy wire attached to the anchor point.


Any tower that was erected prior to August 6, 2014, must be marked as required by the provisions of this section within one year of August 6, 2014. Any tower that is erected on or after August 6, 2014, must be marked as required by this section at the time it is erected.
