A. Where a site in the C-N, C-R, C-S, C-MU, or D-MU zone adjoins an R-1 or R-M zone, either a concrete block masonry wall not less than seven feet in height shall be located on the property line except in a required front yard and suitably maintained or a landscaped buffer be provided as approved by the planning commission.
B. A use not conducted entirely within a completely enclosed structure, on a site across a street or alley from an R-1 or R-M zone shall be screened by a concrete block or masonry wall not less than six feet in height, if the city planning commission finds said use to be unsightly. A landscaped buffer can be approved by the planning commission in place of a required wall as an exception.

Open storage of materials and equipment, except commercial vehicles and used car sales lots, shall be permitted only within an area surrounded and screened by a concrete block or masonry wall not less than six feet in height; provided, that no materials or equipment shall be stored to a height greater than that of the wall or fence.
D. No fence or wall shall exceed seven feet in height if located in a required side or rear yard or three feet in height if located in a required front yard. A fence or wall may be allowed in a required front yard to a height of four feet provided that the additional one-foot height is not of a solid material, upon approval of the city planner.
E. Exceptions may be granted in accordance with Chapter 17.42. (Ord. 2017-01 (part), 2017: Ord. 9605 § 30 (part), 1996: prior code § 7516)
