“Fence” means a structure which serves as a barrier intended to prevent escape or intrusion, to mark a boundary, to shield or screen view, or to serve any similar purpose. All fences shall be constructed only of wood, masonry, stone or metal, or as approved by H.A.R.C.

In all residential zone districts, front yard fences, hedges or walls shall not exceed three and one half feet (3 1/2') above grade. Ornamental details may exceed the maximum height if approved by H.A.R.C.
