Pullman City Zoning Code

17.35 Exceptions

and Special Provisions Pertaining to Uses, Development Regulations, and Performance Standards

This Chapter is to establish provisions for exceptions to standards and requirements imposed by this Title to afford the flexibility necessary to make this Zoning Code as broadly applicable as possible, and to establish provisions for certain uses which are supplementary or in addition to other standards and requirements imposed by this Title.

17.35.010 Purpose.

17.35.020 General Exceptions.

(1) To Building Height Limitations. Except for the height limitations established for Airport Area Height Limitation Overlay Districts, which apply to all structures and structural elements as described in PCC 17.95.050, the building height limitations established in this Title do not apply to the following structures or structural parts:

(a) tanks;

(b) church spires, belfries, or domes;

(d) fire training and hose towers;

(e) smokestacks, chimneys, and vents;

(f) cooling towers;

(g) skylights;

(h) public utility towers and poles when erected and maintained by a public utility which has as its primary purpose the provision of a public service to the general public, not including wireless communication facilities.

The height of these structures may be limited by the City’s building codes; in which case the provisions thereof will control.

(2) To Yard Requirements. The following structures or improvements may be allowed in required yards as follows, subject to the provisions of subsection (3) of this section:

(a) Cornices, eaves, sills, awnings, canopies, bay windows, greenhouse windows, and similar ornamental or structural features may extend no more than 24 inches (2 feet) into any required yard.

(b) Balconies, stairs, ramps, landings, and fire escapes more than 30 inches (2.5 feet) in height above grade that are not covered by a roof may extend:

(i) no more than 36 inches (3 feet) into any required front or side yard; and

(ii) no more than 48 inches (4 feet) into any required rear yard.

(c) Porches, decks, ramps, or landings less than 30 inches (2.5 feet) in height above grade that are not covered by a roof may extend:

(i) no more than 60 inches (5 feet) into any required front or rear yard; and

(ii) no more than 36 inches (3 feet) into any required side yard.

(d) Hard-surfaced areas 30 inches (2.5 feet) or less in height may extend into required yards except so much thereof as may be required to be landscaped or maintained as open space under the provisions of this Title.

(e) Fences may be in required yards subject to the provisions of PCC 17.35.030.

(f) Rockeries and retaining walls may be in required yards if:

(i) the rockery or retaining wall is not being used as a direct structural support for a major structural improvement; and

(ii) the rockery or retaining wall is reasonably necessary to provide support to a cut or slope.

(g) Trellises or support structures for plant material, flagpoles, birdbaths, birdhouses, decorative pools and fountains, decorative lights, and structures required by the City for public safety may be located in required yards.

(3) To Vision Clearance at Intersections. Except in C2, C3, I1, and I2 zoning districts, vision clearance areas must be set up at the intersection of two (2) streets, a street and an alley, or a street and a railroad. The size of the vision clearance area is usually at least 45 feet along the curb line, measured at street level. However, this distance can be reduced to 30 feet on streets with a stop or yield sign, or 15 feet on the alley portion of an intersection. If the angle between streets, alleys, and railroads is less than 30 degrees, the distance for the street should be increased by 10 feet.

A vision clearance area must be kept free of structures, landscaping, or fences between 3 feet and 8 feet tall, measured at street level. However, street signs, traffic signs, utility poles, utility boxes, and retaining walls are allowed in these areas. Buildings built before July 1, 1991, can also be in the vision clearance area. Tree trunks are allowed if the Director of Community Development determines that enough visibility is maintained for vehicles and pedestrians to safely enter and exit the intersection while following traffic rules. If the curb lines at intersections are rounded, the curb lines will be extended in a straight line to the point where they meet.

(iii) The screening requirements of this subsection (11)(f) may be waived if the existing topography of the subject property decreases or eliminates the need for screening, if existing vegetation at the subject property would result in as good or better satisfaction of the provisions of this subsection (11)(f), or if, in the opinion of the Site Plan Review Committee, screening should not be required.

(g) Wireless communication facilities will be designed to be compatible with the natural and built environment. This includes, but is not necessarily limited to, building and structure design and the use of exterior materials and colors harmonious with the character of the surrounding neighborhood.

(m) The site plan review provisions of Chapter 17.135 PCC will apply to all wireless communication facilities.

(n) Minor modifications of existing wireless communication facilities, whether emergency or routine, are allowed, provided there is no remarkably significant change in the visual appearance of the facility. Minor modifications are those modifications, including the addition of transmission and/or reception device(s), to conforming wireless communication facilities that meet the provisions of this subsection (11).

(o) A wireless communication facility will be removed by the facility owner within six months of the date it ceases to be operational.

(12) Interim Use of Land for Parking. Interim use of land for a commercial parking area or other forms of parking may be permitted for a maximum of 10 years, provided the following requirements are met:

Distance will be measured in a straight line between the nearest property line of a sensitive use and the nearest property line of the cannabis production, processing, or retail facility.

(j) The subsequent establishment of a sensitive use listed in subsection (13)(i) of this section within 1,000 feet of a legally established and licensed cannabis production, processing, or retail facility will not render the cannabis production, processing, or retail facility nonconforming regarding location under this subsection (13).

(k) Cannabis production, processing, and retail facilities will comply with all applicable development and administrative standards contained in the Pullman City Code.

(l) Cannabis production, processing, and retail facilities will be designed to include controls and features to prevent odors from traveling off site and being detected from a public place, the public right-of-way, or properties owned or leased by another person or entity.

(m) Cannabis production, processing, and retail facilities will not adversely affect the health or safety of the community and will be operated in a manner as to not create or be considered a nuisance. Nothing in this subsection (13) will be construed as a limitation on the City’s authority to abate any nuisance under PCC Title 5: Health and Sanitation, which may exist from the production, processing, or retailing of recreational cannabis at any location, including from within a fully enclosed and secure building.

(n) No use that constitutes or claims to be a cannabis production, processing, or retail facility for recreational cannabis, which was engaged in that activity prior to the adoption of these regulations, will be deemed to have been a legally established use under the provisions of the Pullman City Code and that use will not be entitled to claim legal nonconforming status.

(o) The production, processing, and retailing of cannabis for any purpose is and remains illegal under federal law. Nothing herein or as provided elsewhere in the Pullman City Code is an authorization to circumvent federal law or provide permission to any person or entity to violate federal law. Only state-licensed cannabis production, processing, or retail facilities may locate in the City and then only pursuant to a license issued by the State of Washington. These provisions are to acknowledge the enactment by Washington voters of Initiative 502 and a state licensing procedure and to permit, but only to the extent provided by state law, cannabis production, processing, or retail facilities to operate in designated zones within the City.
