A. Activities that would remove significant amounts of vegetation, alter land forms, or have other adverse effects on the environment shall be prohibited in designated open space areas.

B. Structures placed or constructed in an open space area, such as benches, trails, and structures associated with gathering places, shall be designed and sited to cause the least possible disturbance to the surrounding environment and the ability of people to enjoy it. This may be achieved through the use of natural or rustic building materials, designs and colors which harmonize with the surrounding environment; the use of existing vegetation as a buffer to avoid visual and other impacts; the use of innovative and sensitive site design to minimize short- and long-term manmade disturbance to the site; or by any other means.
