Towers shall not exceed one hundred twenty five feet (125') in height from existing grade or, if attached to an existing building, one hundred fifty feet (150') less the distance from the existing grade to the point of attachment. A variation to this height requirement may be granted by the zoning board of appeals after receiving an application therefor and holding a public hearing at a regularly scheduled or special meeting. Notice of the time and place of the hearing, together with a brief description of the subject matter shall be published one time not more than thirty (30) nor less than fifteen (15) days prior to the hearing in a newspaper of general circulation in the city. A variation from the height requirement in this section shall be granted by the zoning board of appeals only if the applicant establishes by clear and convincing evidence that it will be unable to provide wireless communication services without such a variation. Under no circumstance shall a tower be erected to a height greater than that required to provide wireless communication services. (Ord. 09/2016, 6-20-2016)
