18.70.040 Setback requirements.

(1) Adjacent to Public Streets. All buildings adjacent to public streets shall be set back a minimum of 30 feet from back of curb. A minimum side and rear setback of 10 feet from back of sidewalk may be allowed where the structure(s) are being incorporated in perimeter fencing or enclosure of some or all of the site.

(2) Side Yard Setbacks.

(a) Compatible Land Uses. Setbacks between buildings of compatible land use may have a zero setback if both buildings are constructed with a one-hour fire wall. Otherwise, the setbacks shall be a minimum of 15 feet for adequate access. Also, building spans shall have separations for rear access every 300 linear feet unless it can be shown that safety vehicles can adequately service the buildings.

(b) Noncompatible Land Uses. When located adjacent to a residential district (excepting recognizable holding zones for future commercial development), side yard setbacks shall be a minimum of 20 feet.

(3) Rear Yard Setbacks. Where adjacent to residential zones, the minimum rear yard setback shall be one foot for every one foot in building height. However, there shall be a minimum setback of 20 feet, unless an access lane is planned; in which case, a minimum of 22 feet is required.

(4) Zero lot lines, or structures constructed with no setback from the property lines, may be allowed for storage unit facilities where the structure(s) are being incorporated in perimeter fencing or enclosure of some or all of the site. A conditional use permit in conjunction with site plan approval is required for zero lot line development. Where adjacent to residential zones, criteria for consideration may include the proposed building height at property line and control of runoff and drainage.

(5) Setbacks shall be measured to the foundation. [Ord. 17-10 § 1 (Exh. A); Ord. 15-18 § 1 (Exh. A); Ord. 9-2-03-2 § 1; Ord. 8-17-99-1 § 1 (Exh. A). Code 1997 § 12-265-020.]

(2) Building Height. Buildings shall not exceed two stories or 35 feet in height, whichever is less, except where adjacent to a regional transportation corridor where buildings may not exceed four stories or 80 feet in height. Where a zero lot line is utilized per RCC 18.70.040(4), building height adjacent to the property line shall not exceed one story.

(3) Bulk. Commercial buildings shall be designed with architectural wall variations at least every 30 feet in linear width. Variations could imply an undulation in wall surface or additional architectural elements that break up the large surface into smaller sections.

(4) Roof.

(a) Roofline.

(i) Parapet Walls. Parapet walls may be constructed in the C-G zone. Parapet walls must be solid and conform to the building materials and architecture of the overall building.

(ii) Height Variation. Parapet walls may not span more than 50 feet without variation in height or depth.

(iii) Rooftop Mechanical Equipment. All rooftop mechanical equipment shall be screened from view at the closest edge of adjacent public rights-of-way by parapet walls or other architectural elements as approved by the planning commission.

(b) Roof Materials. Appropriate roofing materials shall be evaluated by the planning department. However, wood shingles are not permitted.

(5) Exterior Surfaces.

(a) Protected Lower Wall. The lower wall shall be at least one-third the height of the first story. This lower portion of the wall shall consist of brick, tile, stone, decorative cinder block, or decorative concrete.

(b) Upper Wall Materials. The remaining portions of the exterior building may consist of glass, brick, stucco, stone, and treated wood. However, not more than 40 percent of the building’s exterior wall surface may be glass.

(c) Color Palette. Exterior wall surfaces shall be consistent with light earth tones for Victorian architecture and dark brick to match the turn-of-the-century architecture. [Ord. 17-10 § 1 (Exh. A); Ord. 17-08 § 1 (Exh. A); Ord. 8-17-99-1 § 1 (Exh. A). Code 1997 § 12-265-030.]

18.70.070 Development standards.

(1) Site Development.

(a) Building Arrangement. A site plan containing several buildings shall be designed with courtyards when possible.

(b) Site Detail. 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-G 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 with odd-shaped and insufficient-sized lots.

(3) Streetscape. The public right-of-way, which includes the back of curb, park strip, and sidewalk, shall be designed with a meandering sidewalk in the C-G 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 a six-foot solid masonry wall and seven feet of landscaping shall be installed. Businesses with rear loading docks shall have an eight-foot masonry wall plus 10 feet of landscaping. Special considerations may be made when the rear 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. [Ord. 09-07 § 1; Ord. 8-17-99-1 § 1 (Exh. A). Code 1997 § 12-265-035.]

18.70.080 Parking areas.

(1) Arrangement. Parking shall be arranged for convenient access, secured visibility, but also contained by buildings and landscaping. Parking and building arrangements shall avoid a strip mall design. The site plan may be required to group parking lots into courts in order to break up the expanse of parking, thus encouraging parking to be located to the rear and side of the buildings.

(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.

(4) Landscaping. Landscaping medians and borders shall be used to direct circulation flow.

(5) Building Protection. Parked cars shall not block a store front and store access. A minimum of 10 feet shall be required to separate any exterior building wall from parking areas. [Ord. 8-17-99-1 § 1 (Exh. A). Code 1997 § 12-265-040.]

18.70.090 Uses within buildings.

All uses established in the C-G zone shall be conducted entirely within a fully enclosed approved building except those uses deemed by the city council in consideration of the prior recommendation of the planning commission to be customarily and appropriately conducted in the open.
