​​picture of erected barricades​​Prior to the land clearing stage of development, the owner or developer must erect barricades for the protection of the trees and vegetation according to the approved Development Order. Barricades must be installed properly and inspected by County staff prior to vegetation permit issuance. Barricades must remain in place and in sound condition for the entire construction process.

Barricade Placement

  • For all protected native pines, the barricade must be erected around an area at or greater than the full dripline.
  • For all other protected tree species, the barricade must be erected around an area at or greater than two-thirds of the dripline.
  • For all species of mangroves and protected cabbage palms, the barricade must be erected at a minimum distance of six feet from the protected tree(s).
The dripline means a vertical line running from the outermost branches or portion of the tree crown to the ground.

Acceptable Protective Barricades

A physical structure not less than three feet in height composed of lumber no less than one inch by one inch in size for shielding protected trees from the movement of equipment or the storage of equipment, material, debris or fill. Equivalent materials may be used to provide a protective barrier if first approved by the administrator. [LDC 14-374]

Approved Alternate Materials:

Silt screen (a minimum of thirty inches -in height) may be used to enclose and protect trees and vegetation. Staking must be adequate in size and spacing to prevent the screen from sagging or collapsing. Silt screen must be buried or have six inches of fill placed along the entire bottom if it is used as a sediment barrier.  NOTE: Fill material is prohibited within the barricaded area [LDC 14-374], therefore slit screen is often a preferred barricading material.
Enviro-fencing (orange fencing; a minimum of three feet in height) may be used for barricading when staked with a minimum of one inch by one inch wood stakes or appropriate sized steel rods.
Yellow-Rope must have prior approval and may only be used for cleaning of road rights-of-way. When approved, it must have a minimum diameter of 3/8 inch and must be staked with a minimum of one inch by two inch stakes.

Gopher Tortoise Fencing

Chicken Wire, Hardware cloth, or Rat Wire (with holes no more than one inch in diameter) may be used for gopher tortoise protection, when erected a minimum of two feet in height above ground, angled inward towards the tortoise area, and buried a minimum of one foot deep with the underground fence either vertical or angled inward (never outward). These angles help prevent the tortoise from climbing over or digging under the fence. It is imperative that the fence is installed taut, with no sagging.

Vegetation Protection Requirements During Development of Land

  •  No person shall attach any sign, notice or other object to any protected tree in any manner that could prove harmful to the tree, except as necessary in conjunction with activities in the public interest. [14-383(b)]
  • During the construction, the owner or developer shall not cause or permit the cleaning of equipment or material within the outside perimeter of the crown (dripline) or on the nearby ground of any tree or group of trees which is to be preserved. Within the outside perimeter of the crown of any tree -or on nearby ground - the owner or developer shall not cause or permit storage of building material and/or equipment disposal of waste material, or any other material harmful to the life of the tree. [14-383(c)]
  • No person shall permit any unnecessary fire or burning within thirty feet of the dripline of a protected tree. [14-383(d)]
  • Any landscaping activities within the barrier area shall be accomplished with hand labor. [14-383(e)]
  • Prior to the administrator issuing a certificate of occupancy or compliance for any development, building or structure, all trees designated to be preserved that were destroyed during construction shall be replaced by trees of equivalent diameter at chest height tree caliper and of the same species as specified by the administrator, before occupancy or use, unless approval for their removal has been granted under permit [14-383(f)]
  • The administrator may conduct periodic inspections of the site during land clearing and construction. [14-383(g)]
