Posts must be iron pipe (1 5/8 inches outside diameter), wood posts four inches in diameter, or reinforced concrete posts four inches across, sunk at least three feet into soil and encased in concrete, with fencing material such as wood, metal, vinyl, or vinyl-clad wood fastened to them. Electrified fencing and razor wire are prohibited outright. A separate subsection bans masonry fences and vinyl slats woven into chain-link or cyclone fencing, and permits barbed wire only atop security fencing in the Industrial B, C, and D districts.
