Where a rear or side yard abuts any street, alley or sidewalk, fences otherwise permitted in side or rear yards shall not extend into required yards. However, this provision shall not prohibit permitted rail or split rail fences erected in such side or rear yards parallel to and not nearer than one foot to the side or rear property line at a height not to exceed three feet above the natural grade.
