§ 23.38.220. Design standards—General.

Off-street parking facilities shall be designed and maintained in accordance with the standards hereunder, provided that up to thirty percent of parking stalls may be small spaces as described in subsection B. In the alternative, an applicant may propose and, if providing equal or better function, the director may approve alternative parking geometrics consistent with the most recent specific standards promulgated by the Institute of Transportation Engineers or the National Parking Association.

1.

Driveways. Driveways and curb cuts within public rights-of-way shall be in accordance with applicable county requirements, Sections 15.04.070 and 15.04.080, and plans for such shall be submitted to and approved by the director of public works.

2.

Ingress/Egress Requirements.

a.

The department upon recommendation of the director of public works, and after appropriate traffic study, including consideration of total parcel size, frontage on thoroughfares, uses proposed and other vicinity characteristics, shall have the authority to fix the location, width and manner of approach of a vehicular ingress and egress from a building or parking area to a public street and to alter existing ingress or egress as may be required to control street traffic in the interest of public safety and general welfare.

b.

Generally, but not in all cases, the internal circulation system and the ingress and egress to commercial or multifamily developments from an access street shall be so designed that the principal point of automobile cross-traffic on the street occurs at only one point—a point capable of being channelized for turning movements. Access shall be shared with adjoining parcels by placing ingress/egress points on shared lot lines, wherever safe and practical. Where parcels are bounded by more than a single street, generally, but not in all cases, access shall be provided only from the street having the lowest classification in the hierarchy of streets as established by the Director of Public Works.

3.

Maneuvering Areas.

a.

All maneuvering areas, ramps, access drives, etc., shall be provided on the property on which the parking facility is located; however, if such facility adjoins an alley, such alley may be used as a maneuvering area. A garage or carport entered perpendicular to an alley shall be located a minimum of ten feet from the property line. A garage or carport entered parallel to an alley may be placed on the rear property line; provided sight distances are maintained.

b.

Maneuvering areas shall be provided so that no vehicle is obliged to back out of a parking stall onto a street, except into neighborhood collector and local access streets within the R-1/5, RLI, R4, R 4—8 and R6—12 use districts, or where approved by the city engineer.

4.

Parking Surface. All parking lots and access driveways must be paved and designed to meet drainage requirements. Pervious surfaces and other approved dust free surfaces may be used. A maintenance agreement may be required to ensure such surface is properly maintained. However, a parking lot or access driveway may be surfaced with gravel or other approved surface if both of the following criteria apply:

a.

The driveway and parking area contains only one or two parking spaces; and

b.

The shortest feasible route between the road access and the parking area is at least one hundred feet in length.

5.

Landscaping. Parking areas shall be landscaped according to the requirements of Chapter 23.36.

6.

Wheel Stop, Overhang. Appropriate wheel and bumper guards shall be provided to protect landscaped areas, to define parking spaces and to clearly separate the parking area from any abutting street right-of-way and property lines. Vehicles may overhang landscaped areas up to two feet when wheel stops or curbing is provided.

Figure 38-5

7.

Contiguous parking lots shall not exceed one acre in size. Parking lots exceeding one acre in size shall be separated by a minimum ten-foot wide landscaped strip. This strip is in addition to interior and perimeter landscaping and may be used for stormwater management or pedestrian access.

8.

Structured Parking Dimensions. Structured parking facilities may be designed to the general design standards found in Figures 38-4 and 38-5 above, Figure 38-7 below, or to the following structured parking design standard. Within parking structures small spaces shall not exceed thirty percent of spaces within each structure.

	Small Space Dimension	Standard Dimensions
Standard Stall Width	8-foot	9-foot
Standard Stall Depth	16-foot	16-foot
Standard Aisle Width	24-foot	24-foot
Standard Wall-to-Wall	57-foot	57-foot

Small Parking Space Dimensions, Layout and Circulation.

1.

Parking dimensions. No more than thirty percent of spaces shall be smaller than standard sizes. (see small space parking dimensions table below).

	Minimum Small Space Dimension
Stall Width	8-foot
Stall Depth	15-foot

 

 

C.

Bicycle Parking Design Standards.

1.

A long-term bicycle parking facility shall provide for secure extended and short-term use and shall protect the entire bicycle and its components and accessories from theft and weather. Acceptable examples include, in preferred order: bike lockers; bike check-in systems; in-building parking; and limited-access fenced areas with weather protection.

To discourage improper use, a bike locker door should include a see-through window or view hole. For in-building bike parking and limited access fenced areas, fixed structures for locking individual bikes, such as racks, must be provided within the facility. If such an area exceeds five parking spaces, lockable clothing/gear storage lockers must also be provided within the facility. However, facilities such as factories and schools that provide personal lockers are not required to provide additional locker space for bicycle clothing/gear storage.

Exception: For retail uses under five thousand square feet, long-term parking facilities exclusively for bicycles must only be provided only upon request of one or more employees. However, if permanent dedicated space is not provided, a sign must be posted at the primary employee entry reading "Secure Bicycle Parking Provided Upon Request."

2.

A short-term bicycle parking facility shall provide convenient parking with some security and weather protection. Short-term bicycle parking facilities shall include a covered stationary rack. These facilities may be shared among adjoining establishments.

Short-term bicycle parking facilities shall be located either: no further from a public entry than the nearest non-handicapped parking stall; or visible from and within one hundred feet of the public entry; or within fifty feet of the public entry to the building. A directional sign shall be provided if the selected location is not clearly visible from the primary entrance.

3.

Each bicycle parking area shall be separated from motor vehicle parking and maneuvering areas by a barrier, post, or bollard, or by at least five feet of open space. Bicycle parking spaces shall be two feet by six feet each, with no less than a seven foot overhead clearance. A five foot maneuvering aisle shall separate rows of bicycle parking spaces. Bicycle parking facilities shall not be solely accessible by stairs.

4.

Bicycle racks shall be covered in such a manner as to protect the entire bicycle from rain and installed to provide adequate maneuvering space and ensure that the requisite number of bicycle parking spaces remain accessible. The rack shall be permanently affixed to the ground and support the bicycle at two or more points, including at least one point on the frame higher than two feet from the ground. The user shall be able to lock the bicycle with a U-shaped lock or cable lock. Bicycle racks which only support a bicycle front or rear wheel are not permitted,

5.

Long-term bicycle parking facilities may be substituted for short-term bicycle facilities only if the design is consistent with the purpose of short-term facilities.
