      Fence Types Described

TABLE 7.2 - FENCE AND WALL TYPES DESCRIBED AND ILLUSTRATED
TYPE	DESCRIPTION	EXAMPLE PHOTOS
Masonry walls	Masonry walls may be made of brick, concrete block, stone, or a combination of such materials. Unfinished concrete block may not be used as a facing material. These walls may be used on many types of building sites to provide privacy, stabilize terraces, secure pets and children, and delineate or set off landscape features.
Ornamental metal or other (materials designed to resemble ornamental metal)	Decorative metal fencing that has a pattern with a minimum 80 percent or more open. This fencing is most often used in urban areas and small lot subdivisions where the need to balance access control with visibility exists.
Woven wire, including chain link	Wire woven into a fencing material that has a pattern with a minimum 80 percent or more open. This fencing is most appropriate for agricultural areas to control livestock and delineate pasture.
Wood or other (materials designed to resemble wood such as composite or vinyl)	Wooden picket or slat fencing either opaque (privacy fencing) or semi-opaque. Wooden slats and pickets on these fences must be a minimum of 3 inches wide.
Mixed-material	Fences typically combining two or more fence materials. This fence type does not include woven wire fencing where fence posts made of wood or other materials may be used. These fences are often found in suburban or rural areas as visually lower-impact pet or child enclosures.
Hedge	A fence or boundary formed by closely growing bushes or shrubs planted in a fashion that provides an opaque or nearly opaque barrier.
Barbed wire / sharp-pointed fences	A fence discouraging climbing or sitting through the use of sharp points or objects welded to or embedded in fence posts or walls.
Flood retaining walls	Walls in this category are designed and intended to contain or redirect flood waters.
Sports	These fences typically surround active sport areas such as tennis courts, volleyball courts, basketball courts, baseball fields, and football fields. They serve to keep the ball close to the field of play and to control access to the play area. Fences must be made of coated chain link or similar material.
Security	Security walls and fences, including but not limited to razor wire, concertina wire, and similar high security fencing material required to secure industrial properties.

   5. 5.
      The Zoning Administrator may order all other diseased, infested, dying, dead, or damaged landscape plants required in this Section to be replaced within an eight-year period from the date the Certificate of Zoning Compliance was granted. This does not apply to required buffer yards which are covered in subsection 5 above.

      Unless specifically required, trees and shrubs do not have to be equally spaced but may be grouped together.
   4. 4.
      Where a property has unique conditions, the following adjustments are permitted:

      1. a.
         When there is a topographical change of 15 feet or greater, a buffer yard width may be reduced by 50 percent. The required landscaping must be placed at the top of the bank.
      2. b.
         When there is an undisturbed area twice as wide as the required buffer yard width, the number of required trees can be reduced by 50 percent.

These barriers shall remain in place during heavy construction on the site and no vehicles, machinery, tools, chemicals, construction materials, or temporary soil deposits may be permitted within the barriers, nor may any notice or other object be nailed or stapled to protected trees.
      3. c.
         If these trees are removed by any means, the property owner shall be responsible to provide new landscaping that meets these requirements.
   6. 6.
      Under conditions where a strict interpretation of the requirements of this Section may be either physically impossible or create practical difficulties, an alternative compliance procedure may be used to maintain the spirit rather than the literal interpretation of the Ordinance. The proposed solution must equal or exceed standard landscaping requirements. Requests to the Zoning Administrator for use of alternative landscaping schemes are justified only when one (1) or more of the following conditions apply:

      1. a.
         The sites involve space limitations or unusually shaped parcels;
      2. b.
         Topography, soil, vegetation, or other site conditions are such that full compliance is impossible or impractical;
      3. c.
         Due to a change of use of an existing site, the required buffer is larger than can be provided;
      4. d.
         Safety considerations are involved; or

        A tree preservation plan must be prepared by a Certified Arborist and submitted with a required Final Development Plan or permit application. The determination of which trees shall be saved shall be guided by the following principles:

       1. a.
          The practicability of arranging site plan components around existing features. In general, plans for groups of structures should be designed to preserve tree masses, individual tree specimens, and small stands of trees. Natural woodland areas shall be protected wherever feasible.
       2. b.
          The condition of the vegetation with respect to continued vitality.
       3. c.
          The practical and economic possibility of designing the location and grades of proposed structures and paving to preserve existing vegetation.
       4. d.
          The desirability or lack thereof a particular tree or species by reason of its appearance, historic or ecological significance, botanical characteristics, and the function the vegetation would fulfill as a site plan component.
       5. e.
          The potential for interference with utility services or with passage or visibility along roads or walkways.
       6. f.
          The possibility of preserving the vegetation while meeting the development needs through pruning rather than removal.

          1. 1.
             Development Plans for sites with existing trees or stands of trees should make reasonable efforts to protect and incorporate them into the overall site design.
          2. 2.
              Prior to the approval of the development and the issuance of a permit, the developer shall inventory trees on the site which have a caliper of eight inches or greater, following the “American Standard for Nursery Stock” standards that are intended to be saved. The inventory shall contain the location, size, and common name of an existing stand-alone tree, areas of dense trees or shrubs, and other natural features. Existing trees saved in the development of the site shall be credited toward the landscaping requirements as identified in sub-subsection 3 below.
          3. 3.
             To encourage tree preservation, each tree preserved greater than eight inch caliper shall convert as credits for required landscaping. Credits for each preserved eight inch caliper tree shall be:

             1. a.
                Two (2) required shade trees; or
             2. b.
                Four (4) ornamental trees.
          4. 4.
             Barriers shall be used to protect trees during the development of the site. Substantial barriers shall be specified on the landscape plan and shall be placed at or beyond the critical root zone (an area equal to a 1-foot radius from the base of the tree’s trunk for each one inch of the tree’s trunk diameter at 4.5 feet above grade). These barriers shall remain in place during heavy construction on the site and no vehicles, machinery, tools, chemicals, construction materials, or temporary soil deposits may be permitted within the barriers, nor may any notice or other object be nailed or stapled to protected trees.
