<br />the required rear yard dimension by the minimum lot width prescribed for these zoning districts. This unob-
<br />structed open area may be located in a side yard and /or in the area between the principal structure and the rear lot
<br />line and shall have a minimum dimension of not less than 15 feet.
<br />Additions to principal structures in the R- I- 8,500, R -1- 7,500, R -1 -6,500 and RM -4,000 districts may encroach
<br />into otherwise required rear yards to within 15 feet of the rear lot line, provided that there remains a single unob-
<br />structed open space with an area equal to 80 percent of the area obtained by multiplying the required rear yard
<br />dimension by the minimum lot width prescribed for these zoning districts. This unobstructed area may be located
<br />in a side yard and /or in the area between the principal structure and the rear lot line and shall have a minimum
<br />dimension of not less than 15 feet.
<br />No structure referred to in this section projecting into the required rear yard shall exceed one story in height.
<br />F. Fences, walls, and hedges not over six feet in height, walks, driveways and retaining walls may occupy a required
<br />side or rear yard, except that solid fences, walls, and hedges in the side yard on the street corner of a corner lot
<br />may not exceed a height of 30 inches, and open fencing, such as wrought iron, split rail, picket style, or other
<br />similar types of open fencing, may not exceed a maximum height of 42 inches. In conjunction with the open
<br />fence, a solid base of brick or split face block up to a height of 18 inches may be constructed so long as the total
<br />fence height does not exceed 42 inches, and decorative columns, caps, or pilasters up to a height of 48 inches,
<br />generally separated by a distance of six feet may be constructed. "Open picket style fencing" is defined as fenc-
<br />ing which consists of narrow vertical boards, generally three inches to four inches in width, with at least 33 per-
<br />cent of the fence area being open to view. No such structure or hedge shall pose a traffic sight obstruction. In the
<br />C -S, C -A, 1 -1' and I -G districts, fences as high as eight feet may be allowed in conjunction with outdoor storage
<br />areas. The upper two feet of such fences may contain barbed wire. Permission of the zoning administrator shall
<br />be required for such over height fences and may be denied if the zoning administrator determines the appearance
<br />of such fencing would conflict with the purposes of this title or if such fencing would be detrimental to the public
<br />health or general welfare.
<br />In the R -1 -6,500 and R -1 -7,500 districts, fences, walls and hedges not over six feet in height may be located to
<br />within five feet of the side property line on the street side of a corner lot between the rear property line and a
<br />point set back 15 feet from the front corner of the residence closest to the side street.
<br />G. Fences, walls and hedges greater than six feet but not over eight feet in height may occupy a required side or rear
<br />yard upon approval by the zoning administrator.
<br />1. Application for an over height fence, wall or hedge pursuant to this subsection shall be made with the zon-
<br />ing administrator and shall be subject to design review.
<br />2. The zoning administrator may require noticing up to 300 feet from the property lines in order to continue
<br />processing the design review application. If the determination to notice the application is made, it may be
<br />subject to a zoning administrator hearing.
<br />3. If a zoning administrator hearing is conducted, the zoning administrator may approve, conditionally ap-
<br />prove, or deny the application and shall find that the application:
<br />a. Conforms to the objectives of this title;
<br />b. Assists in providing privacy, in attenuating sound transmission, and /or in reducing other annoyance
<br />from neighboring properties; and
<br />c. Does not significantly impact upon the aesthetics and safety of the neighborhood nor the light and air
<br />to all affected properties.
<br />4. The zoning administrator's decision may be appealed to the planning commission. (Ord. 1994 § 2, 2009;
