A fence that abuts a property line with street frontage shall have a minimum setback of 10 feet from the curb line and shall be set back from any sidewalk a minimum of one foot. Fences along the longer frontage on corner lots are permitted to be a maximum of six feet in height and may be an opaque fence, provided they shall be no closer than 25 feet of the corner of lot joining the two frontages, with the fence permitted to extend to the rear property line. Along the rest of the longer and shorter frontages an open fence of maximum four feet in height is permitted. In no case shall the fence be located within the right-of-way.
