The base of the antenna support structure and any related structures and equipment shall be screened and secured from the street and adjacent properties in a manner acceptable to the Board. If deemed necessary by the Board to mitigate the visual impact of the antenna and related structures and equipment, the color, materials, and design of the entire antenna and related structures and equipment shall be required to modified in appearance so as to blend in with the surrounding environment, as determined by the Board to be appropriate in the particular situation. The foregoing may include, but shall not necessarily be limited to, such modifications as special paint treatment, concealment through architectural means such as a bell tower, steeple, etc., or the use of camouflage through simulated foliage so as to appear as a tree.
