(1) The City is divided into the following underlying zoning districts:

(2) Overlay Zoning Districts. To regulate uses in zoning districts or portions of zoning districts where unique or unusual circumstances warrant additional or more restrictive standards, the following overlay districts are established and may apply in various areas:

(3) Floating Zoning Districts. To regulate developments that necessitate substantial planning and design efforts and public review, the following floating zoning districts are established:

(1) At Time Of Annexation. All land annexed to the City will be classified at the time of annexation by ordinance into one (1) or more of the zoning districts established by this Chapter.

(2) Preannexation. Whenever, prior to annexation, an amendment to the Comprehensive Plan, to the text of this Title, or to the Official Zoning Map has been adopted by the City pursuant to RCW 35A.14.330 as now existing or is amended, the amendment will be effective upon the date of annexation as described in the annexation ordinance.

(3) Prezone Map. The location and boundaries of all prezone districts established by this Title are shown on the map entitled “Official Zoning Map of the City of Pullman.” The map and any amendments thereto will be dated with their effective dates and signed by the Mayor and Director of Finance and Administrative Services. This map is referred to as the “Official Zoning Map” and is adopted as a part of this Title by reference thereto. The district boundaries may be amended in accordance with Chapter 17.115 PCC and such amendments will also be adopted by reference as part of this Title.

(4) Recommendation of Planning Commission. Upon notification of any proposed annexation not already designated into a district on the Comprehensive Plan and Official Zoning Map, the Commission will review and, after holding a public hearing as described in Chapter 17.170 PCC, recommend to the Council, within one (1) year of such notification, a plan designation and zoning district classification for the land involved in the annexation. Thereafter, the Council will review the matter pursuant to Chapter 17.180 PCC. Action taken to assign a plan designation and zoning district classification in this manner may occur before or after the property under consideration is annexed to the City. (Ord. 25-08 §1 (Att. A), 2025; Ord. 03-33 §29, 2003; Ord. 87-9 §1, 1987. Formerly 17.65.030).

(1) Zoning District Boundary Lines. Zoning district boundary lines are intended to follow lot lines, and the centerlines of alleys, streets, rights-of-way, and watercourses, unless such boundary lines are fixed by dimensions shown on the Official Zoning Map.

(2) Vacated Streets, Alleys, or Public Ways. Whenever any street, alley, or other public way is vacated, any zoning district bounded by a side of such street, alley, or public way will be automatically extended to the center of the vacated street, alley, or public way, and all of the area included in the vacation will then be subject to the regulations of the extended districts.

(3) District Boundaries. Where district boundaries are shown as approximately following lot lines, such lot lines will be construed to be the boundaries. If a district boundary divides a lot into two (2) or more districts, the location of the boundary unless indicated by dimensions shown on the Official Zoning Map will be determined by the use of the map scale shown thereon.

(4) Division of a Single Lot. Where a district boundary line as shown on the Official Zoning Map divides a parcel of property in single ownership at the time of the passage of this Title, the use permitted on the least restricted portion of that parcel may extend into the portion lying in the more restrictive district for a distance of no more than 50 feet. (Ord. 25-08 §1 (Att. A), 2025; Ord. 22-2 §8, 2022; Ord. 87-9 §1, 1987. Formerly 17.65.070).
