All outdoor trash or disposal facilities in an "MR" (Multi-Family), "B" (Business) or "I" (Industrial) District, and any dumpster in any district, shall be located in the rear of the zoning lot and the building located on the lot or as approved. All such facilities shall be appropriately screened in the opinion of the Village Board from adjoining properties and in a manner which is compatible with the building site design for the zoning lot. School recycle bins are exempt from the screening provision of this chapter. Any such outdoor trash or disposal system must be maintained to avoid the existence of litter or the dispersal of trash outside the screened enclosure. The accumulation of litter or trash is not permitted.
