In the LDSF, R-1, R-2, or R-3 zoning district, and as an accessory use to a dwelling in any zoning district, fences may be erected and maintained to a height not to exceed six feet in the side or rear yard area, and to a height not to exceed four feet in the front yard area, except on corner lots. On corner lots any fence exceeding four feet in height shall not extend closer to either street than twenty feet from a property line. Fences exceeding the height limitations may be authorized for buffering conflicting land uses, or required site screening, or through the administrative adjustment process of Chapter 10.30. (Ord. 1634, § 34, 2004.)
