§ 18.80.070 Development standards.

(1) 
Site Development.
(a) 
Building Arrangement. The site plan shall be designed such that the parking is located to the side and/or rear of the buildings. A site plan containing several buildings shall be arranged symmetrically around courtyards when possible.
(b) 
Site Detail – Walkways, Courtyards and Plazas. Materials for walks, courtyards, and plazas shall be related to the materials of adjacent buildings and shall be a non-skid finish. Design shall encourage comfortable and safe pedestrian use, including landscaping, seating areas, and lighting as according to the adopted Riverton City lighting standards.
(2) 
Minimum Lot Size. Development within the C-PO zone shall not be less than one-half acre in size, unless it is a pad site included as part of a larger development. Each parcel shall also be of sufficient size to assure compliance with the city's off-street parking, landscaping, and site plan requirements.
The city may deny a commercial use on property where insufficient lot size or lot shape is such that it creates illogical traffic circulation, or is not conducive to the intent of this title. The city will encourage the consolidation of lots for commercial uses where odd-shaped and insufficient-sized lots exist.
(3) 
Streetscape. The public right-of-way, which includes the back of curb, park strip, and sidewalk, shall be designed with a straight sidewalk in the C-PO zone. Within the park strip, one-and-one-half-inch caliper trees shall be planted every 25 feet on center according to the streetscape master plan. Behind the sidewalk, the landscaping plan is encouraged to include berms that rise one foot over every three feet in width.
(4) 
Buffering Between Noncompatible Land Uses. Between noncompatible land uses, a minimum of six-foot masonry wall and seven feet of landscaping shall be installed. Businesses with a rear loading dock shall have an eight-foot masonry wall plus 10 feet of landscaping. Special considerations may be made when the rear or side yard is adjacent to compatible or future commercial holding zones. The landscaped strip shall include a combination of trees and shrubs that, along with the fence, shall maintain proper screening from adjacent residential uses. Unless otherwise specified by the city council as part of site plan approval, no land disturbance or construction not associated with placement and installation of fencing shall be allowed prior to installation of fencing required by ordinance or by action of the city council.
(5) 
Dumpster Enclosures and Outdoor Storage Areas. Any garbage dumpster, garbage can, or recycling bin shall be enclosed by a solid wall or fence constructed with durable materials that are designed consistent with the building as approved by the land use authority. The enclosure must surround all four sides and be accessed by a gate. The enclosure wall and gate shall be a minimum of 12 inches higher than the trash receptacle bin. These areas shall be oriented away from public view and shall be well maintained. Where a garbage dumpster is used, the enclosure shall be a solid masonry wall and the gate shall be painted or powder coated metal. The land use authority may approve an enclosure with a solid wood or solid vinyl fence and gate for an enclosure that is exclusively for residential style garbage cans or recycle bins that will be rolled to the street for pick up.
(Code 1997 § 12-275-035; Ord. 8-17-99-1 § 1 (Exh. A); Ord. 09-07 § 1; Ord. 25-22 § 1 (Exh. A))

§ 18.80.080 Parking areas.

(1) 
Arrangement. Parking shall be arranged for convenient access, secured visibility, but also contained by buildings and landscaping. The site plan shall be designed to encourage parking locations to be on the side and/or rear of the buildings, except where adjacent to a regional transportation corridor. In this situation, to encourage a campus atmosphere, parking may be located on all sides of buildings. Parking and building arrangements shall avoid a strip mall design. A site plan containing several buildings shall be required to group parking lots symmetrically around courtyards when possible.
(2) 
Pedestrian Access. Parking lots containing more than 150 spaces must install safe, unobstructed pedestrian paths leading to the store frontage.
(3) 
Shade. Parking lots shall have a minimum shade canopy of 20 percent at point of mature tree growth. Planters for trees shall be a minimum of five feet by five feet. Planter areas may be counted toward the required open space.
