All commercial and multi-family residential uses that provide trash and/or garbage collection areas shall have such areas enclosed on at least three sides by a solid wall or fence adequate in height to screen the containers, if such area is not within an enclosed building or structure. Provisions for adequate vehicular access to and from such area or areas for collection of trash and/or garbage as determined by the Planning and Zoning Administrator shall be required. All trash shall be stored in completely enclosed containers as to prevent the dispersal of trash by wind and other conditions. Design approval for the wall or fence must be obtained from the Planning and Zoning Administrator.
