In all residential districts, no fence, partition, screen, structure, wall or other device used as a fence, as herein defined, shall be erected, constructed or installed which is over five feet in height.

All finished fences shall be installed so that the finished surface shall face away from the lot of the property owner installing same.

Fences shall only be of one color.

No fence shall be erected in a residential district in the front yard, in the facing yard with respect to corner lots or along a public right-of-way, unless the fence is uniformly less than 50% solid. Notwithstanding the foregoing, fences more than 50% solid shall be permitted in the rear portion of the facing yard from the rear line of the principal building extended to the facing street, so long as the fence is substantially perpendicular to the facing street.

The following fences and fencing materials are specifically prohibited:

All chain link fences erected shall be erected with the closed loop at the top of the fence.

No fence shall be constructed within the right-of-way of any public street.

Fences shall be erected in a manner so as to permit the flow of natural drainage and shall not cause surface water to be blocked or dammed to create ponding.

Any fence, wall or similar structure, as well as shrubbery which unduly cuts off light or air which may cause a nuisance, a fire hazard or a dangerous condition or an obstruction to combating fires or an obstruction to men and equipment for combating fires which may affect public safety, is hereby expressly prohibited.

"Retaining wall" means a structure that is designed and constructed to stabilize two generally horizontal surfaces which are vertically displaced.

No retaining wall shall be built in a residential zone until a building permit is issued by the Construction Official.

No retaining wall shall be erected within 25 feet of a street center line nor within (10) feet of the street right-of-way, or be installed in such a manner as to constitute a traffic or other hazard.

The maximum height of a retaining wall in the front yard and side yard (including the facing yard on a corner lot) which is essentially parallel to or facing the street shall be three feet. For purposes of this subsection, a facing yard on a corner lot shall be deemed to extend to the rear lot line. A maximum of one additional retaining wall of a height no greater than three feet may be erected in the front or side yard so long as such walls are tiered with a minimum horizontal distance of four feet between the face of the lower wall and the base of the higher wall.

The maximum height of a retaining wall in the front yard and side yard that is essentially perpendicular to the street, i.e., a retaining wall constructed for purposes of stabilizing a driveway cut, shall be six feet up to the line of the building envelope. No height limitation is established for retaining walls within the building envelope.

The maximum height of a retaining wall in the rear yard shall be five feet. Additional retaining walls of a height no greater than five feet may be erected in the rear yard so long as such walls are tiered with a minimum horizontal distance of four feet between the face of the lower wall and the base of the higher wall.

Any fence placed on the top of a retaining wall shall be set back four feet from the face of the retaining wall measured horizontally.

Any retaining wall over three feet in height must be designed by a licensed professional engineer.

All existing retaining walls which do not conform to the provisions of this section may be continued as they presently exist and may be repaired or replaced to the same or lesser dimensions, line and grade.
