18.145.020 Provision for off-street parking.

Off-street parking shall be provided for when any new building is erected or any remodeled building is enlarged or increased in capacity. Parking shall consist of asphalt or concrete surface off-street area with adequate provisions for paved ingress and egress by standard-sized automobiles as hereinafter provided. All required parking facilities shall be maintained so long as any use requiring such facilities continues. [Ord. 8-17-99-1 § 1 (Exh. A); Ord. 3-3-98-2 § 1 (Exh. A). Code 1997 § 12-315-010.]

The dimensions of each off-street parking space shall be nine and one-half feet by 19 feet for angled or 90-degree-angle spaces, or nine feet by 22 feet for parallel spaces exclusive of access drives or aisles. However, where stalls are located against curbed areas, stall depths may be reduced to 18 feet (nine and one-half feet by 18 feet) for angled or 90-degree spaces. Dimensions for parking spaces and drive aisles shall be as shown in Table 18.145.030.

(5) Entrance by Forward Motion. Off-street parking areas shall allow vehicles to enter and exit from a public street by forward motion only.

(6) Maintenance. Pavement, striping, landscaping, paintings, lighting and all other parking area components shall be maintained to prevent deterioration and safety hazards.

No tandem parking (one space blocking access behind another) shall be allowed, except for conventional single-family dwellings. [Ord. 7-6-04-2; Ord. 6-1-04-1; Ord. 8-17-99-1 § 1 (Exh. A); Ord. 3-3-98-2 § 1 (Exh. A). Code 1997 § 12-315-015.]

18.145.040 Calculating parking requirements.

The following shall apply when calculating parking spaces for residential and commercial uses:

(1) Square Footage Basis. Whenever parking requirements are based on square footage, calculations shall be based on gross square footage of the building or use.

(2) Number of Employees Basis. When parking regulations are based on the number of employees, parking calculations shall use the largest number of employees who work at any one shift. Where shift changes may cause substantial overcrowding of parking facilities, the planning commission may require additional spaces.

(3) Inclusion of On-Street Parking. Available on-street parking spaces may not be used to meet the requirements set forth herein. No development plans shall be based on the assumption that excess vehicles can be parked on public streets.

(4) Multiple Uses. When a structure or parcel contains multiple uses, more than one parking standard may apply.

(5) Fractional Numbers. If, when calculating the number of parking spaces, a fractional number is obtained, one parking space shall be required for each fraction.

(6) Transportation System Management. For office and industrial uses with parking lots over 300 parking spaces, a maximum of 20 percent reduction in parking spaces may be permitted when an approved transportation system management (TSM) plan is in place. TSMs must include a minimum of one dedicated bus stop located on site and/or a van pool system. [Ord. 8-17-99-1 § 1 (Exh. A); Ord. 10-27-98-2 § 1 (Exh. A); Ord. 3-3-98-2 § 1 (Exh. A).

Trees, both deciduous and evergreen, shall be placed in the strip with spacing of no less than 30-foot intervals, and shall comply with all ratio requirements listed herein.

(2) Curbing. All landscaped areas abutting any paved surface shall be curbed. Boundary landscaping around the perimeter of the parking areas shall be separated by a concrete curb or wall at least six inches higher than the parking surface.

(3) Sight Distance. At intersections of streets, driveways, sidewalks, etc., landscaping shall be limited to a height of not more than three feet above grade. The grade at the said intersections shall not be bermed or raised for a distribution of 15 feet back from the intersection to allow for sight distance.

(4) Medians. Any traffic median or island, either on or off site, shall be fully landscaped with trees, shrubs, or, grass, or a mixture of the three. In any case, however, the landscaping shall include trees unless deemed inappropriate by the planning commission, or puts the safety of patrons, residents, or others in jeopardy by its design.

(5) Islands within Parking Areas. On double rows of parking stalls, there shall be one 40-foot by nine-foot landscaped island on each end of all parking rows, plus one 40-foot by nine-foot landscaped island to be placed at a minimum of every twentieth parking space. On single rows of parking or where it abuts a sidewalk, there shall be one 20-foot by nine-foot landscaped island a minimum of every 10 spaces. Landscaped islands at the ends of parking rows shall be placed and shaped in such a manner as to help direct traffic through the parking area. There shall be a break in parking rows at a maximum of 40 parking stalls for each double row of parking for the purpose of facilitating traffic circulation on the site. Each island on double parking rows shall include a minimum of two trees per planter. Islands on a single parking row shall have a minimum of one tree per planter. The purpose of the landscaped area is to provide shade relief to the parking area and all vegetation shall be placed to this end.

(6) Boundary Strips. All landscaped boundary strips shall be a minimum of five feet in width.

(7) Site Plan – Landscape Planting Plan. All landscaping shall be completed in accordance with the approved site plan and landscape planting plan and shall be installed prior to the issuance of a certificate of occupancy for the building, except where weather conditions are prohibitive. In such cases an extension period of six months is permitted but all bonding shall be withheld until full compliance is determined.

(8) Parking Abutting Building. Parking which abuts the side or front of buildings shall be, as a minimum, separated in the following ways:

(a) In the front of the building by a four-foot sidewalk and a five-foot landscaped strip or as approved by the city council upon recommendation from the planning commission.

(9) Land Area Covered by Landscaping. All land area not occupied by buildings, structures, hard surface, vehicular driveways, or pedestrian walkways shall be landscaped and maintained in a weed-free condition.

(10) Snow Stacking. Every parking lot design shall plan for a snow stacking area to accommodate the stacking volume of a two-foot snow base over the entire parking lot. Parking lot snow removal shall include shoveling of raised walkways, where used. [Ord. 8-17-99-1 § 1 (Exh. A); Ord. 10-27-98-2 § 1 (Exh. A); Ord. 3-3-98-2 § 1 (Exh. A). Code 1997 § 12-315-025.]

Parking shall include pleasant pedestrian access to building front. This shall include an unobstructed walkway to the building front a minimum 10 feet in width. Walkways shall be placed, at a minimum, through the center of the parking area and along the front of buildings to serve as pedestrian access to adjoining buildings. The center walkway shall be placed roughly at midpoint of the parking area, but shall align with the front entrance to the main building. Trees along the center walkway shall be placed a minimum of every 30 feet, but are encouraged to be offset from one another to create a feeling of greater coverage. Where parking configurations are long and narrow, the center walkway may be removed as long as there is a maximum of 250 feet to the nearest walkway. Additional elements such as pergolas, covered walkways or tree-lined walkways shall be encouraged along pedestrian access. Where the developer(s) desires to have a driveway access at the center of the parking area, a pedestrian access shall be placed on either side of the driveway. Where this is the case, the landscaping shall be a minimum of five feet in width with a minimum six-foot sidewalk. Trees shall be placed at the said intervals. [Ord. 8-17-99-1 § 1 (Exh.

(1) Easement. If a building, structure, or improvement requiring parking is located upon a parcel under different ownership, or upon a different lot from that upon which the required parking is provided, an easement from the owner(s) of the property thus to be used shall be executed and recorded in the office of the Salt Lake County recorder in a form first approved by the city council; provided, that the dominant tenant of the building, structure, or improvement exists within said city.
