A. Review Authority. Parking lot design and drainage shall be subject to review and approval of the City Transportation Manager.

B. Maintenance of parking areas. All parking lots shall be kept clean and in good repair at all times. Breaks in paved surfaces shall be repaired promptly. Broken or splintered wheel stops shall be replaced so that their function will not be impaired.

C. All signing and striping, including that for private parking lots, shall conform to the Manual of Uniform Traffic Control Devices (MUTCD). Individual spaces shall be marked with painted stripes.

D. Location. Parking spaces shall not be permitted in any setback except as otherwise specified in this title. For single-family and duplex dwellings, vehicle, vessel, recreational vehicle trailer parking is permitted in the front yard setback provided it is: located on a legally established driveway; located out of sight triangles as per Chapter 20.895 VMC; does not extend into city right-of-way; and is currently licensed and registered. Parking of motor homes, trailers, recreational vehicles and boats is allowed in one side or rear setback on an impervious surface and served by a paved driveway. Such parking must be screened from adjoining properties by a six-foot sight-obscuring fence or hedge.

E. No parking space shall be located where backing maneuvers from such a space would interfere with traffic flow to/from a public street to the parking area, generally within 20' of a circulation aisle-way near a public street access point.

F. Driveways. Driveways which provide access to off-street parking or loading from public streets shall comply with the following:

1. Driveways from the street to off-street parking or loading areas shall be designed and constructed to facilitate the flow of traffic and provide maximum safety for pedestrians. At a minimum all driveways shall meet arterial access spacing standards; on arterial roadways shared driveways and cross-access easements may be required to improve arterial efficiency and safety consistent with access management practices detailed in NCHRP Report 420.

2. Where driveways are gated, even temporarily, the driveway approach shall be designed such that vehicles approaching or leaving the gated drive can queue to enter/exit the traffic stream without blocking the sidewalk or the street traffic, and shall not impede internal site circulation. Design of gated driveways shall be subject to review and approval by the City Transportation Manager.

3. Driveways shall be improved with a permanent surface including but not limited to asphalt, concrete, brick or masonry or other material approved by the Planning Official. Applicants are encouraged to use City and Department of Ecology alternative paving Best Management Practices to enhance on-site water quality where appropriate based on anticipated use.

4. Except for single-family and duplex residences, groups of more than two parking spaces shall be served by a driveway so that no backing movements or other maneuvering within a street or other public right-of-way is necessary.

5. Loading/unloading driveways. If an on-site drop-off is provided, the driveway shall be designed for continuous forward flow of passenger vehicles.

G. On-site vehicle stacking for drive-through use.

1. All uses providing drive-through services as defined by this Chapter shall provide a stacking lane on the same site for inbound vehicles as noted in Table 20.945-1. Stacking lane requirements shall be determined through the review process, be based upon an approved traffic study and may either exceed or fall below the guidelines detailed in Table 20.945.040-1.

2. Stacking lanes must be designed so that they do not interfere with parking and vehicle, pedestrian and bicycle circulation. Stacking lanes for the purpose of selling food must provide at least one clearly marked parking space per service window for the use of vehicles waiting for an order to be filled.

3. No portion of a stacking lane shall be located in a setback except at the points of connection between the site and public or private streets.

H. Pedestrian access, circulation and connections. The following standards apply to multi-family, commercial, industrial and institutional uses in all zones:

1. The applicant shall extend pedestrian circulation routes to sidewalks and transit stops along streets abutting the site, to pedestrian facilities that extend to the edge of the site from off-site, and to the edge of the site in the direction of existing, approved or proposed off-site pedestrian and transit facilities.

2. Pedestrian circulation routes shall also connect structures and uses on the site, such as buildings, vehicle and bicycle parking areas, children’s play areas, required outdoor areas, open spaces, plazas, resting areas and viewpoints.

3. To the extent practicable, the pedestrian circulation system shall be designed to minimize the distance a pedestrian needs to walk between typical origins and destinations of and off the site, including transit stops, public sidewalks and building entrances. Circuitous routes generally should be avoided except for an appropriate purpose given the use or setting.

4. Where pedestrian or bicycle routes cross access, maneuvering, parking or loading areas, the crossing must be clearly identified by using elevation changes, speed bumps, a different paving material, and other method that effectively alerts drivers, pedestrians and cyclists of the location and nature of the crossing. Striping is strongly discouraged as the only method of identification of pedestrian crossings. When striping is used, it must be continuously maintained in perpetuity in an effective manner by the property owner.

5. Where a pedestrian or bicycle route is parallel and adjacent to an auto travel lane or parking area, the pedestrian or bicycle route must be safely separated from the auto travel lane by using a raised path, a raised curb, bollards, landscaping or other physical barrier.

6. Lighting. The on-site pedestrian circulation system must be lighted to a level of 0.5 foot candle, except for handicapped accessible areas which must be lighted to 1.0 foot candle. Such lighting shall be directed in a manner to prevent glare on nearby residential areas.

7. Pedestrian route dimensions. In all commercial zones, the primary pedestrian connection between the main entrance and the fronting arterial shall be a minimum of 8' unobstructed width. All other pedestrian connections shall be a minimum of 6' unobstructed width. The Planning Official may modify these standards for minor expansions of existing uses that face site-specific challenges.

8. Required pedestrian circulation routes shall be improved with an asphalt, concrete or other approved all-weather surface; provided, pedestrian circulation routes through recreational or open space areas may be improved with a material consistent with their purpose and the characteristics of their location.

9. Connections. The pedestrian system must be connected to site and adjacent streets and nearby transit stops. The pedestrian system must also connect public open space or parks, commercial, office and institutional developments when existing development does not preclude such connection. Development patterns must not preclude eventual site-to-site connections, even if an adjacent site is not planned for development at the time of the applicant’s development. Connections between buildings and the street shall be no greater than 200' apart.

I. Parking lot landscaping.

1. Purpose. The following landscaping standards are intended to improve and soften the appearance of parking areas; reduce the visual impact of parking areas from sidewalks, streets, and especially from adjacent residential zones; shade and cool parking areas; reduce the amount and rate of stormwater runoff from vehicle areas; and improve air quality.

2. Perimeter Landscaping. Any off-street parking area, other than for a single-family or duplex dwelling, shall be effectively screened by a sight-obscuring fence, wall or evergreen planting on each side which adjoins property situated in a residential zone, the premises of any school or like institution, or a public or private street. Screening along a common property line shall be 6' high. Landscape screening shall be capable of attaining a height of 6' within 2 years of planting. Screening along all public or private streets shall be a minimum of 3' high.

3. Interior Landscaping. Interior landscaping must be provided for sites containing more than 20 parking spaces. At least 10% of the parking and maneuvering areas, not including driveway areas, must be landscaped.

a. Standards. The landscape materials must meet the general standards below:

1. The landscaping must be dispersed throughout the parking area. All of the required landscape area may be in the parking area, or some may be in the loading areas.

2. Perimeter landscaping may not substitute for interior landscaping. However, interior landscaping may join perimeter landscaping as long as it extends at least four feet into the parking areas from the perimeter landscape line.

b. Individual tree-planting spaces. Where an individual tree is planted in a space surrounded by pavement, the planting area must have a minimum dimension of six feet with each tree placed in the middle.

c. Required landscape materials for parking lot landscaping. Landscape materials for parking lot interior and perimeter landscaping must be provided as follows:

1. Tree required. At least one tree must be provided for every 10 parking stalls. Existing trees may be used to meet this standard. At lease one tree shall be planted in each landscape island. Broadleaf trees must be at least 2 caliper inches at the time of planting and conifer trees must be at least 5' tall at the time of planting. Trees must be dispersed throughout the parking area to provide shade for the parking area. Some trees may be grouped, but the groups must be dispersed.

2. Shrubs required. At least one shrub must be provided for every 30 sq. ft. of required landscaped area. Shrubs must be at least the one-gallon container size.

3. Ground cover required. All of the landscaped areas that is not planted with trees and shrubs must be planted in ground cover plants, which may include grasses. Paths made of paving stones, flagstones, bricks, pavement, or similar materials may provide access across landscaped areas, but the surface area of impermeable materials does not count toward the required landscaped area.

4. Native Species. Planting of native species is encouraged.

J. Parking lot surfacing.

1. All areas used for the parking or storage or maneuvering of any vehicle shall be improved with asphalt, concrete or other permanent surface approved by the Planning Official; The Planning Official may approve the use of City and Department of Ecology alternative paving Best Management Practices to enhance on-site water quality where determined to be appropriate based on type and frequency of anticipated use.

2. Parking areas to be used primarily for temporary staging of construction equipment and temporary parking for the facility during construction may be surfaced in gravel when authorized by the approval authority at the time the site development approval is given. The Planning Official may require the property owner to remove the gravel immediately following construction or enter into an agreement to pave the parking area: (1) within a specified period of time after its establishment; or (2) if there is a change in the types or weights of vehicles utilizing the parking area; or (3) if there is evidence of adverse effects upon adjacent roadways, water courses or properties. Such an agreement shall be executed as a condition of approval of the plan to establish the gravel parking area

K. Parking lot and access striping.

1. Except for single-family and duplex residences, any area intended to be used to meet the off-street vehicle parking requirements as contained in this chapter shall have all parking spaces clearly marked; and

2. All interior drives and access aisles shall be clearly marked and signed to show direction of flow and maintain vehicular and pedestrian safety.

L. Wheel stops. Parking spaces along the boundaries of a parking lot or adjacent to interior landscaped areas or sidewalks shall be provided with a wheel stop or bumper rail at least 6" high located 2' back from the front of the parking stall. The front 2' of the parking stall may be concrete, asphalt or low- lying landscape material that does not exceed the height of the wheel stop, provided sidewalks or other pedestrian paths are not obstructed.

M. Drainage. Off-street parking and loading areas shall be sloped to drain in accordance with specifications approved by the Director of Public Works. These areas shall be drained to prevent the flow of water onto the right-of-way, across pedestrian facilities, or onto adjacent properties unless specifically authorized by the Director of Public Works.

N. Lighting. All off-street parking areas larger than 5,550 sq. ft. shall be illuminated. Public parks that close at dusk are exempted from this provision. All lighting shall be directed away from any adjacent residential zone.

2. The width of each parking space includes a stripe that separates each space.

3. Up to 50% of all required on-site vehicular parking spaces may be compact spaces. Such spaces shall be marked as “compact” or “C”.

4. Clustering. No more than an average of 10 parking spaces shall be placed side by side without an intervening break provided by a circulation aisleway, pedestrian walkway, or landscaping. If an average of no more than 10 side-by-side stalls is maintained overall, up to 15 stalls may be located side-by-side. Where landscaping provides a break in the group of spaces, the landscape island shall extend at least 1' into the circulation aisleway to provide a visual narrowing of the circulation aisleway.

5. A portion of a parking space may be landscaped instead of paved as follows:

a. The landscaped area may be up to 2' of the front of the space as measured from a line parallel to the direction of the bumper of a vehicle using the space.

b. Landscaping must be ground cover plants; and

c. The landscaped area counts towards parking lot interior landscaping requirements, but not perimeter landscaping requirements, and shall not obstruct the minimum width requirements for pedestrian circulation.

6. Other parking angles, such as but not limited to 30 degrees or 75 degrees may be approved by the Planning Official, with dimensional requirements consistent with those illustrated in Table 20.945.040-2.

7. Minimum standards for a standard parking stall’s length and width, aisle width, and maneuvering space in a parking structure shall be determined as noted in Table 20.945.040-2. (Ord. M-4289 § 4, 2019; Ord. M-4195 § 1, 2017; Ord. M-4034 § 32, 2012; Ord. M-3931 § 32, 2009; Ord. M-3847 § 15, 2007; Ord. M-3840 § 45, 2007; Ord. M-3643, 2004)
