Sodding and/or rock ground requirements will still be applied if a shrubbery fence is provided.

§ 154.595 BUFFERYARD REQUIREMENTS.

   (A)   Intent. The provisions of this section are to provide specific landscape screening and bufferyard requirements to reduce the incompatibility between zoning districts of different intensity and type.

The specific requirements are identified in the following sections and the accompanying table in § 154.599. Landscaping and screening requirements for off-street parking areas apply to the side of the property abutting a public street right-of-way. A list of prohibited trees is provided in § 154.597.
