PART 2. PERIMETER BUFFERS
(E) Buffers.
(1) Buffer defined. A buffer is a specified land area, located parallel to and within the outer perimeter of a lot and extending to the lot line, together with the planting and landscaping required on the land. A buffer may also contain, or be required to contain, a barrier such as a berm or wall where such additional screening is necessary to achieve the desired level of buffering between various land use activities. A buffer is not intended to be commensurate with the term "yard" or "setback."
(2) Buffer types. There are four types of required buffers that may occur on any given parcel, as described further in this section.
(a) Street buffers.
1. All new development with frontage on a commercial street or designated minor thoroughfare shall provide a Class A buffer as set forth in division (E)(3) of this section.
2. Double frontage lots abutting a collector street or residential collector street shall provide a Class A buffer along the entire rear yard frontage.
(b) Parking buffers. Parking buffer requirements are set forth in Part 1 of this section.
(c) Compatibility buffers. Perimeter compatibility is required along the boundaries of all incompatible zoning districts or existing uses, whichever is more restrictive. If the existing use of an adjacent property is nonconforming then the required buffer shall be determined by zoning district instead of existing use. Table 4-5 shall be used to determine the required buffer classification between adjacent districts.
