Solid fences, walls, hedges and retaining walls not more than seven feet in height may occupy any required yard or other space, except that fences, walls, hedges and retaining walls shall be no higher than three feet when located in the required front yard setback area, in the required setback areas along the side street of a corner lot and along the rear or side lot line of a reversed corner lot where it abuts the front yard of the adjoining key lot. Walls and retaining walls over four feet in height require engineering and a permit.

      (7)   Sight distance triangle - obstructions. No obstruction to view in excess of three feet in height shall be placed in any corner or reverse corner lot within a triangular area formed by the extension of the lot line to a point of intersection and a line connecting them at a distance of 30 feet to said intersection. Except for natural land formations, a sight distance triangle for a driveway with a distance of ten feet from back of sidewalk towards the dwelling and ten feet along the sidewalk in either direction shall be maintained free of obstructions in excess of three feet in height.
      (8)   Fence permits. A fence permit, issued by the Community Development Department shall be obtained prior to the erection of any fence over six feet in height within the city.
