Landscaping. Landscaping shall be required to screen as much as possible of any equipment storage facility in order to soften the appearance of any equipment storage facility. The Township may permit any combination of existing vegetation, topography, walls, decorative fences, or other features, instead of landscaping, if they achieve the same degree of screening as the required landscaping. When an antenna is mounted on an existing structure, and other equipment is housed inside an existing structure, landscaping shall not be required. However, existing vegetation on and around the site shall be preserved to the greatest extent possible.
