B.
Determination Transition Buffer Requirements. The following procedure shall be followed in determining if a transition buffer is required. Using the matrix in Subsection (C), Transition Buffer Requirements, of this Section:
1.
Identify the minimum zoning classification required to accommodate the proposed use. These classifications are listed under "Proposed Zoning" in the first column.
2.
For transition buffer requirements, identify the actual zoning classification of the abutting site(s). These classifications are listed under the heading "Adjacent Zoning."
Determine if a transition buffer is required by crossing the previously identified proposed zoning with the adjacent zoning. The letter "R" indicates that a transition buffer is required, otherwise, no transition buffer is required. |
