With regard to the requirements for the siting of wireless (radio, television, digital (PCS) and cellular telecommunications) towers and facilities, it is the express objective of this section to provide reasonable opportunities for the siting of such facilities in the various business and commercial zones throughout the Borough of Highlands without adversely impacting the visual quality and character of the Borough's diverse residential neighborhoods. Further, it is the policy of the Borough that existing buildings and structures be used where appropriate, with tower facilities considered only as a last resort. Wireless tower facilities should be located or collocated on property that is owned by the Borough, other public entity or a utility company, where possible. The specific site standards provided herein are designed to enable equal access by wireless companies to the airwaves, while using vertical elements, such as trees and buildings to provide "angles of occlusion" that completely or partially block or screen views of a freestanding tower from residential uses and zones depending on the viewing distance and relative elevations.
