To preserve the aesthetic and scenic value of the Village, new telecommunications facilities shall be sited on existing telecommunications towers, unless the applicant demonstrates unequivocally that collocation is not possible. Any existing permit shall, regardless of additional expense or modification of facilities, allow and encourage collocation on its facilities. If collocation is not possible, such facilities shall be located in the area already in use for telecommunications towers, as close as possible to existing towers. At the option of the Village Board, any telecommunications towers, antennas or accessory structures shall be located on Village-owned property.
