Landscaping and bufferyards. The bufferyard is a unit of yard together with the planting thereon. Both the amount of land and the type and amount of planting specified for each bufferyard requirement are designed to minimize nuisances between adjacent land uses. The planting units required of bufferyards have been calculated to ensure that they do, in fact, function as "buffers". Bufferyards shall be required to separate land uses from each other in order to eliminate or minimize potential nuisances such as dirt, litter, noise, glare of lights, signs, and unsightly building or parking areas, or to provide spacing to reduce adverse impacts of noise, odor, or danger from fires or explosions. Proposed uses in any district that are specifically agricultural, as defined under "agriculture" in § 155.220. General definitions are exempt from providing bufferyards unless otherwise specified.
