(a)   Materials.  All fences built or repaired shall have posts made of either iron pipe, at least one and five-eights inches outside diameter, or any other material of equal stability sunk in concrete at least three feet, or treated wood posts four inches in diameter or reinforced concrete posts four inches across, set in the earth three feet and having a height above the average grade of the two adjoining lots of not less than three feet.  Iron pipe having an outside diameter of at least one and five-eighths inches, or any other material of equal stability, using a "drive anchor" installation mechanism or any other anchoring mechanism of equal stability and rigidity, may be used if approved by the Building and Engineering Department in lieu of setting posts in three feet of concrete.  Masonry walls shall have footings as specified in the current Michigan Building Code.  Partitions or line fences shall not exceed six feet in height, unless provided for elsewhere in this chapter, except for enclosing an entire rear yard for a private swimming pool. Chain link, board or other materials shall be properly fastened to the post.  All fence materials must be approved by the Building and Engineering Department.
   All fences herein required shall be constructed solely of new materials approved by the Building and Engineering Department to be durable, weather-resistant and easily maintained.
   (b)   Construction.  All fences shall be constructed in such a manner that all structural members, including braces, posts, poles and other projections, shall be on the interior side of the fence.
   (c)   Attachment. Attaching one fence to another to form a single barrier is expressly prohibited.  Only a single fence may be installed on any parcel of land running any particular direction to act as a barrier.  A second or parallel fence is prohibited, unless for a dog run.
   (d)   Design Requirements.  Painted fences, in hues other than white, earth or wood tones, shall be subject to the review and approval of the Building Official and the following design standards:
      (1)   The appearance, color, texture and materials being used will preserve property values in the immediate vicinity and will not adversely affect any property values.
      (2)   The appearance of the fence will not detract from the general harmony of, and is compatible with, the structure and other developments already existing in the immediate vicinity.
      (3)   The appearance of the fence will not be garish or otherwise offensive to the sense of sight to passersby.
      (4)   Fence appearance will tend to minimize or prevent discordant and unsightly surroundings in the immediate neighborhood.
   (e)   Sharp Projections.  No owner or lessee of any building in the City, or their respective agents, shall erect or cause to be erected or maintained on or about its exterior building line, or upon fences, or upon any portion of the sidewalk adjacent to such building, any railing, fence, guard or other projection on which there is affixed, placed or in any manner attached any spike, nail or other sharp-pointed instrument of any kind.  No wire or other fence materials shall be affixed to the fence with the top edge having any sharp or pointed projections of any kind.  However, if such fence is constructed of pickets, such pickets must be made of not less than one inch by three-inch material and shall have an angle at the top of not less than ninety degrees.
   (f)   Barbed Wire.  No owner or lessee of any property, or their respective agents, shall construct or maintain a barbed wire fence except in those areas zoned Industrial I and Industrial II. Except that fences six feet high or higher may have barbed wire attached to arms or brackets extending inward over private property owned by the person erecting and paying for such fence, but no such  barbed wire shall be placed at any point nearer to the ground than six feet.  However, the aforementioned arms for barbed wire on six-foot fences may be placed only on the lines enclosing industrial property.  Further, the arms shall project over the industrial side of the line only on such portions of the fence, which are twenty-five feet or more from the front lot line.  Nothing herein to the contrary, barbed wire fencing in all residential zoning districts, commercial, or along property lines abutting a residential zone is prohibited.
   (g)   Electrification.  Fences shall not contain electric current or a charge of electricity.  This provision shall not apply to electrical barriers, provided below grade, used to contain household pets.
   (h)   Corner Lots and Corner Clearance.  On corner lots, fencing may be erected along the side street property line no further toward the front lot line than the rear building line, except that a side entrance may be included in such fencing.  In areas of heavy school traffic, special  conditions may be given to corner lots at the discretion of the Board of Zoning Appeals.  In cases of residential lots abutting public, commercial or industrial alleys or properties, public playfields, parking lots, parks, school grounds or recreation area, approved fences not exceeding six feet in height may be erected and maintained along side or rear lot lines abutting such alleys or properties.
   When a driveway intersects a public right of way or when the subject property abuts the intersection of public rights of way, all landscaping and/or fencing within the corner triangular area described below shall permit unobstructed cross-visibility.  Fencing or landscaping located in the triangular area shall not be permitted to exceed a height of more than thirty inches above the centerline elevation of abutting pavement.  Trees may be maintained in this area provided that all branches are trimmed to maintain a clear vision for a vertical height of eight feet above the roadway surface.
   The triangular area referred to above is:
      (1)   The area formed at the corner intersection of a public right-of-way and a driveway, two sides of the triangular area being ten feet in length measured along the right-of-way line and driveway line and the third side being a line connecting these two sides.
      (2)   The area formed at a corner intersection of two public right-of-way lines, the two sides of the triangular area being twenty-five feet in length measured along the abutting public right-of-way lines and the third side being a line connecting these two sides.
