Ord. 3-26 pdf	2026-03-03	Amends Zoning: Definitions; Amends Land Use Matrix	Ch 17.09, Ch 17.13

§ 17.13.010 Interpretation of land use matrix.

The land use matrix in this chapter identifies uses permitted in each individual zoning district. The zoning district is located on the vertical column and the use is located on the horizontal row of this matrix.

If a dash appears in the box at the intersection of the column and the row, the use is not permitted in that district.

If the letter "P" appears in the box at the intersection of the column and the row, the use is permitted in that district.

If the letter "C" appears in the box at the intersection of the column and the row, the use is conditionally permitted subject to the conditional use permit review procedures and criteria specified in WRMC 17.66.030.

If the letter "S" appears in the box at the intersection of the column and the row, the use is secondarily permitted in that district.

If a footnote appears in the box at the intersection of the column and the row, the use may be permitted subject to the appropriate review process indicated above and the specific conditions indicated by the corresponding footnote.

All applicable requirements shall govern a use whether or not they are cross-referenced in the matrix. To determine whether a particular use is allowed in a particular zoning district and location, all relevant regulations must also be consulted in addition to this matrix.

Any use that is not specifically permitted, conditionally permitted or secondarily permitted under the West Richland Municipal Code shall be prohibited.
