A. Access criteria to parking areas.

1. Parking areas in commercial, office, industrial, public and multi-family residential projects shall be provided with suitable maneuvering room so that all vehicles therein may enter an abutting street in a forward direction without backing onto a street.

2. If more than two parking spaces are located on a site, backing a vehicle across a property line abutting a street is prohibited.

3. Use of a required parking space shall not require more than two vehicle maneuverings, except for parallel parking spaces.

4. Parking spaces shall be located to preclude vehicular maneuvering or back up within 10 feet of a vehicular entrance to the property.

5. Except for single-family residences, duplexes and affordable housing projects, each parking space shall have unobstructed access from a street or alley or from an aisle or drive connecting with a street or an alley, nor shall the moving of one vehicle be required in order to gain access to a parking space.

6. Entrances from and exits to streets shall be provided at locations approved by the public works director.

B. On-site circulation criteria.

1. Parking and circulation shall be designed so that emergency and other public service vehicles can provide service without backing unreasonable distances or making other dangerous or hazardous turning movements.

2. Separate vehicular and pedestrian circulation systems should be provided within a parking area, where possible. Pedestrian linkages between uses in commercial developments should be emphasized, including distinct pedestrian access from parking areas in large commercial developments.

C. Parking lot surfacing.

1. Parking areas, aisles, and access drives shall be paved so as to provide a durable, dustless surface and shall be so graded and drained as to dispose of surface water without damage to private or public properties, streets or alleys.

2. All parking and loading areas shall be surfaced with a minimum thickness of two inches of asphalt concrete (Type A) over a minimum thickness of six inches of Class II aggregate base material or a minimum thickness of six inches of Portland cement concrete. Such surfacing shall be permanently maintained free of structural defects. Pervious paving may be used to reduce post-construction stormwater runoff where maintenance is guaranteed to ensure the long-term permeability of the paving.

3. Notwithstanding the above, parking lots with 10 or fewer required parking spaces, at the discretion of the planning and building director or planning commission, may make use of alternate overlay material such as pavers, chip-seal and rock material provided it is affixed with an underlying seal coat. However, within 10 feet of a sidewalk or roadway, the driveway shall meet the asphalt or concrete requirements of this subsection.

D. Bumper rails or guards are to be provided at locations prescribed by the public works director where needed for safety and to protect property.

E. Lighting of parking areas.

1. Parking areas designed to accommodate three or more vehicles in other than vehicle sales areas shall have lighting facilities capable of providing sufficient illumination at every point of the parking area.

2. Freestanding light fixtures shall be limited to a maximum height of 14 feet above finished grade.

3. All illumination, including security lighting, shall be arranged so as to reflect downward and away from the night sky, adjoining properties and rights-of-way.

F. Landscaping and screening.

1. Landscaping and screening for parking areas shall be installed as required in HMC 20.16.100.

2. Walls, dense landscaping and other opaque screens within parking areas shall have a maximum height of 30 inches to allow for maximum visibility.

G. Slope and drainage criteria.

1. Parking areas designed exclusively for parking and vehicle maneuvering shall be designed and improved with grades not to exceed a five percent slope.

2. Driveways used exclusively for ingress and egress or interior parking lot circulation shall be designed and improved with grades not to exceed a 10 percent slope.

3. All off-street parking and loading facilities shall be so designed that surface water will not drain over any sidewalk.

H. Marking of parking stalls.

1. All parking spaces shall be demarcated in a manner clearly showing the layout of the intended parking stalls. Such striping shall be maintained in a clear and visible manner.

2. All pavement markings shall be white, with the exception of handicapped parking markings.

I. No repair work or servicing of vehicles shall be conducted in a parking area. (Ord. 1106 § 2 (Exh. A § 1925), 2011.)

20.16.170 Location of vehicular parking

Required vehicular parking areas shall be located as follows:

A. Except as provided below, off-street parking facilities required by this article shall be located on the same site as the use for which the spaces are required, or on an adjoining site or a site separated by an alley from the use for which the spaces are required.

B. When off-street parking facilities are provided in compliance with the requirements of this article on a site other than the site on which the use to be served by the parking facilities is located, an indenture shall be recorded in the office of the County Recorder designating the off-street facility and the use to be served, with legal descriptions of all sites involved, and certifying that the off-street parking facility shall not be used for any other purpose unless the restriction is removed by a resolution of the City Council. An attested copy of the recorded indenture shall be filed with the planning and building director and building official. Upon submission of satisfactory evidence that other off-street parking facilities have been provided in compliance with the requirements of this article or that the use has ceased or been altered so as to no longer require the off-street parking facility, the Council may, by resolution, remove the restriction.

C. In the Downtown Commercial and Public Zoning Districts, a conditional use permit may be granted to permit off-street vehicular parking spaces to be separated if located within 300 feet of the use for which the spaces are required, measured by the shortest distance of pedestrian access.

D. Location in required residential yards.

1. In residential zoning districts, required off-street vehicular parking spaces shall not be located within a required front yard or within the street side yard of a corner lot.

2. On a corner side street, required parking spaces shall be located at least 20 feet distant from the back of the sidewalk, excepting covered parking, which may be located five feet from the back of the sidewalk. If no sidewalk exists, the front of the structure shall be located five feet or at least 20 feet from the edge of pavement.

3. In the Grove Street Mixed Use Zoning District, an accessory structure used as a garage or carport and accessed by a rear alley shall be located five feet or at least 20 feet from the edge of the alley pavement. (Ord. 1106 § 2 (Exh. A § 1930), 2011.)
