Towers that lawfully existed prior to the adoption of this chapter are allowed to continue their use as they presently exist. This code does not make lawful any towers that are not lawfully approved on the date the ordinance codified in this code is adopted. Routine maintenance is permitted on such lawful preexisting towers.

Lawfully existing towers may be replaced as long as the replacement is located on the same property, no closer to the nearest property line than the existing tower, no taller than the existing tower, has a width no more than 10 percent larger than the existing tower and has identical lighting and painting. The tower being replaced must be removed within 30 days of completion of the replacement tower. Any other changes or modifications to a replacement tower must be treated as new construction, and must comply with the requirements of this chapter. [Ord. NS-2328, 2019; Ord. NS-2158, 2011; Ord.
