During demolition and /or development or construction, including installation of <br />irrigation systems or any other underground installations, protective barriers shall <br />be placed around all trees to be preserved and shall remain in place throughout the <br />period of construction and /or demolition in order to prevent the destruction or <br />damaging of roots, stems or crowns of such trees. <br />2. The protective barrier shall be clearly visible and be made of a minimum of one - <br />inch wide stakes spaced a minimum five feet to eight feet and 3 feet above ground <br />and linked together with brightly colored plastic tape or other similar material. <br />The protective barrier shall be placed at the dripline of the protected tree, unless <br />the structure has been permitted by the Planning and Zoning Commission to be <br />erected within the dripline of a tree with a wide canopy.
