18.52.050 Parking design, development, and maintenance standards.
Required parking areas shall be designed, constructed and maintained in compliance with this section:
A. Location of Parking. Off-street parking areas shall be located as follows:
1. Residential Parking. Residential parking shall be located on the same site as each residential dwelling unit served; except for a mixed-use development as defined by ACC 18.04.625. No required residential parking space shall occupy any unimproved area within the required front setback, or side and rear setback, except as allowed by subsection E of this section, Surfacing of Parking Areas.
2. Nonresidential Parking. Nonresidential parking shall be located on the same site as the use served, or off site. If parking is to be located off site it is subject to the following requirements:
a. The lot or area to be utilized for parking shall be legally encumbered by an easement or other appropriate means to ensure continuous use of the parking facilities following the procedure contained in Table 18.52.030(1), Joint Use of Parking Facilities.
b. Whenever required parking facilities are located off site, sidewalks, or an approved pedestrian facility, shall be provided connecting the satellite parking facility to the development being served.
B. Access to Parking. Access to parking shall be provided as follows for all parking areas other than for individual single-family dwellings and duplexes:
1. The location, design and construction of entrances and exits from the street right-of-way shall be determined by the city engineer.
2. A commercial or industrial use shall have access driveways from the public or private street that are not intersected by a parking aisle, parking space, or another access driveway for a minimum distance of 40 feet from the street right-of-way, to provide a queuing area for vehicles entering and exiting the parking area. The city engineer may require an increase or a decrease of this as determined by criteria set forth in the engineering design standards.
C. Access to Adjacent Sites. The city may require that the design of a parking area to provide vehicle and pedestrian connections to parking areas on adjacent properties or to connect with adjoining public walkways (when a reciprocal access easement is available or can reasonably be provided).
D. Parking Stall and Aisle Dimensional Standards.
1. Minimum Dimensions. Each parking space and parking lot aisle shall comply with the minimum dimension requirements in Table 18.52.050 and further displayed in Figure 18.52.050.

2. Compact Parking. Compact spaces may be allowed within a parking lot up to a maximum of 30 percent of the total number of spaces. This maximum percentage can be increased to 50 percent when approval is obtained by the planning director following the procedures contained in ACC 18.52.135, Alternative parking layouts. Compact spaces can be clustered or dispersed throughout the parking lot. Every compact parking space created pursuant to this section shall be clearly identified as such by painting the word “COMPACT” in upper case block letters, using white paint, on the pavement within the space or through the use of signage.
3. Vehicle Overhang. Vehicular overhang of up to two feet is permitted, provided no vehicle shall overhang into a sidewalk or walkway which would reduce the unencumbered width of a sidewalk or walkway to less than four feet. A vehicle is permitted to overhang into a landscaped area by two feet; provided, that the required landscape area of trees and shrubs are not reduced in quantity and not subject to potential damage.
E. Surfacing of Parking Areas. Areas used for parking on private property, including interior driveways and access to a public street, shall be paved with asphalt concrete, cement concrete pavement, or pervious pavement and shall have appropriate bumper guards where needed. Paving is not required for temporary parking facilities that have obtained a temporary use permit pursuant to the requirements of Chapter 18.46A ACC, Temporary Uses; however, dust mitigation is required. Where a driveway crosses an improved public right-of-way, it shall be constructed with cement concrete. All pavement sections shall be designed to support the post development traffic loads anticipated due to the intended use as approved by the city engineer.
1. Alternative paving systems may be provided subject to the approval of the city. The alternative must provide results equivalent to paving.
2. For parking areas serving single-family dwellings and duplexes when located on individual lots, this section shall apply:
a. Each off-street parking space shall be connected to an improved street or alley by a driveway a minimum of 11 feet in width.
b. Not more than 50 percent of the front yard or 800 square feet, whichever is smaller, can be used as off-street parking surface. For the purposes of calculating the allowable area under this section, the front yard shall be the area between the right-of-way and the portion of the single-family dwelling’s front facade farthest from the right-of-way. The width of the front yard shall extend to each side property line.
c. Driveways that exclusively serve nonrequired off-street parking spaces are also subject to the surfacing requirement.
d. Off-street vehicle parking spaces, including those for trailers, recreational vehicles, and boats on trailers, that are provided in addition to those required pursuant to Table 18.52.020 shall be paved with one of the surfaces listed above (subsection E of this section), or gravel; provided, that weeds, mud or other fine material do not work their way to the surface of the gravel; and provided, that loose gravel is contained on the subject property.
e. Boats not on trailers shall not be stored in the front yard.
F. Grades of Access Driveways. The grade of access driveways for off-street parking areas shall be subject to the driveway regulations contained in Chapter 10.04 of the engineering design standards.
G. Sidewalks or Pedestrian Walkways. Sidewalks or pedestrian walkways shall be visibly marked with differentiated pavement or other methods such as reflective/LED markers, double row of landscaping, or raised pavement.
H. Landscaping. See Chapter 18.50 ACC.
I. Lighting. See Chapter 18.55 ACC. (Ord. 6657 § 2, 2017; Ord. 6388 § 1, 2011; Ord. 6231 § 7, 2009; Ord. 4949 § 1, 1997; Ord. 4229 § 2, 1987.)
