§ 82-16.404. Design and layout.  


Latest version.
  • (a)

    Parking Area Design Requirements. Each parking area must meet the following parking area design requirements:

    (1)

    General Requirements. Each off-street parking area must be designed with appropriate maneuvering areas and means of vehicular access to a street adjacent to or abutting the parking area. Each parking area must be designed to allow circulation of vehicles from one driveway aisle to another driveway aisle, or must provide, at the end of the driveway aisle, a turn-around area that is marked to prohibit parking and has a minimum area equivalent to one standard parking space.

    (2)

    Access Requirements. If an off-street parking area does not abut a street, an access drive between the street and the parking area must be provided. The access drive must measure at least twelve feet wide if it will be used for one-way traffic, and at least twenty feet wide if it will be used for two-way traffic. Each entrance to and exit from an off-street parking area must be located and designed to provide efficient and safe traffic flow between the parking area and the street. If a driveway aisle intersects directly with the adjacent or abutting street, that intersection must be at least eighteen feet away from the parking space nearest to it. Each off-street parking area within a residential zoning district (R-, D-1, M-), commercial zoning district (O-1, A-O, C-B, N-B, R-B, C-, C-M), industrial zoning district (L-I, W-3, H-I), or planned unit zoning district (P-1), must be designed so that vehicles are not required to back out of the parking area onto an abutting or adjacent street. If a pedestrian sidewalk is adjacent to a parking space, at least five feet of width of the sidewalk must be unobstructed by any bumper overhang.

    (3)

    Driveway Aisles. Each parking space in a parking area must be accessed by a driveway aisle. If parking spaces with different angles of parking are accessed by the driveway aisle, the required driveway aisle width is the largest driveway aisle width that would be required for any of those parking spaces. Driveway aisle width is measured between the closest points of two parking spaces, or two curbs, or a parking space and a curb, that are directly opposite on each side of the driveway aisle.

    (4)

    Changes in Grade. When there is a change in grade between a parking area and an abutting or adjacent street, the gradient of each access point or access driveway may be up to a five percent gradient with no transitions. For a gradient greater than five percent, a twenty-foot long transition with a gradient of no more than five percent must be provided before or after the change in grade. For a gradient greater than fourteen percent, up to the maximum permitted gradient of twenty percent, a transition of one half of the gradient must be provided for a minimum of eight feet before, and a minimum of eight feet after, the change in grade.

    (5)

    Surfacing. Except as specified in this subsection (a)(5), each required off-street parking area must be surfaced with a continuous asphalt or Portland cement binder pavement, or similar paving material, with a weight rating necessary to accommodate emergency vehicles, as deemed necessary by the zoning administrator in consultation with the fire district or department having jurisdiction over the parking area. At least ten percent of the total paved area of a parking area must be paved with porous asphalt, pervious concrete, permeable pavers, or unit pavers that the zoning administrator, in consultation with the fire district or department having jurisdiction over the parking area, determines has a weight rating necessary to accommodate emergency vehicles. The parking area surface must be graded and drained to prevent the pooling of water.

    (6)

    Prohibitions. No off-street parking area may be used for automobile sales, storage, repair work, dismantling, or servicing of any kind.

    (7)

    Striping, Markings, and Signage. Each parking space must be marked with striping and must open directly on a driveway aisle meeting the width requirements set forth in this section. Each parking area must include signage and directional markings deemed necessary by the zoning administrator to ensure sufficient traffic circulation and safety.

    (8)

    Lighting. For safety and security, each parking area in a non-residential zoning district (any zoning district other than a R-, D-1 or M- district) must include lighting that adequately illuminates the parking area. Lighting must be directed downward and away from adjacent areas and public streets and rights of way, to prevent glare (overwhelming direct light creating a potential hazard), or excessive light spill-over (unreasonable amounts of light extending beyond the intended area or property line), as seen from those areas, streets, or rights of way. To provide for the general safety of adjacent vehicular traffic and the privacy and well being of residential areas, the lighting intensity may not be greater than reasonably required to safely and securely illuminate the parking area. Each lighting fixture must be consistently maintained to ensure broken or burnt-out bulbs are replaced, fixtures remain clean and graffiti and rust free, and painted fixtures do not chip or peel. Whenever possible, lighting fixtures must be equipped with energy efficient bulbs.

    (9)

    Screening and Buffers. If a parking area is adjacent to property within a residential zoning district (R-, D-1, or M-) or a parcel used for residential uses within a planned unit district (P-1), the parking area must include one of the following between the parking area and that zoning district:

    (A)

    A six-foot high solid fence or masonry wall (block, brick, or natural or concrete stone) and vegetation that, when mature, will cover a portion of the fence or wall; or

    (B)

    Landscape screening of at least six feet in height. Up to three feet, or half of the total height, whichever is less, may consist of planter boxes, raised beds, or similar improvements, and the remaining amount of screening must be shrubbery or other plants that, when planted, will provide a complete screen.

    (b)

    Parking Space Design and Layout. Each parking space within a parking area must meet all of the following requirements:

    (1)

    Parking Space Sizes. Except as provided in this subsection, each parking space in a parking area must be a standard size parking space. If twelve or more parking spaces are required by this chapter, a maximum of twenty-five percent of the total required parking spaces may be designated for compact vehicles. Each compact-vehicle parking space must provide pavement markings or signage identifying it for use by compact vehicles. Each standard size parking space, each compact-vehicle off-street parking space, and each driveway aisle must have the following minimum dimensions:

    (A)

    For each space with an angle of parking of zero degrees:

    Dimension Standard Spaces Compact Spaces
    Space Width 8'6" 7'6"
    Curb Length 21'6" 19'
    Space Depth 8'6" 7'6"
    Driveway Aisle Width One-way travel: 12'
    Two-way travel: 20'
    One-way travel: 12'
    Two-way travel: 20'

     

    (B)

    For each space with an angle of parking of forty-five degrees:

    45° Dimension Standard Spaces Compact Spaces
    Space Width 8'6" 7'6"
    Curb Length 12' 10'6"
    Depth Perpendicular to Curb 18'6" 16'6"
    Short Depth 13'6" 12'
    Long Depth 22' 19'6"
    Driveway Aisle Width One-way travel: 13'
    Two-way travel: 20'
    One-way travel: 13'
    Two-way travel: 20'

     

    (C)

    For each space with an angle of parking of ninety degrees:

    82-16.404-3.png

    Dimension Standard Spaces Compact Spaces
    Space Width 8'6" 7'6"
    Curb Length 8'6" 7'6"
    Space Depth 18' 16'
    Driveway Aisle Width One-way travel: 25'
    Two-way travel: 25'
    One-way travel: 25'
    Two-way travel: 25'

     

    (2)

    Non-Standard Angles of Parking. If a parking space in any parking area will have an angle of parking other than zero degrees, forty-five degrees, or ninety degrees, the zoning administrator will calculate the parking space dimensions to provide approximately the same amount of space that is required for a parking space with a zero-degree angle of parking. For calculations for a parking space with an angle of parking that is greater than zero degrees and less than forty-five degrees, the required driveway aisle width is thirteen feet for one-way travel, and twenty feet for two-way travel. For calculations for a parking space with an angle of parking that is greater than forty-five degrees, the required driveway aisle width is twenty-five feet for one-way and two-way travel.

    (3)

    Motorcycle Parking. Any off-street parking area with twenty or more standard size parking spaces may include up to six designated motorcycle parking spaces. Each designated motorcycle parking space must have a length of at least eight and one-half feet, and a width of at least three feet. Motorcycle parking spaces may not be counted towards the minimum number of parking spaces required by this chapter.

    (c)

    Landscaping Design and Layout. Landscaped areas must be provided within any off-street parking area other than an enclosed parking structure, and must meet the following design and layout requirements:

    (1)

    Each landscaped area within or adjacent to a parking area must be bordered by a curb that is at least six inches high and at least six inches wide. Each curb must be constructed of the same material that is used to pave the parking area, or another paving material that is authorized under this chapter and as approved by the zoning administrator.

    (2)

    Each landscaped area must be designed so that pedestrians are not required to cross the landscaped area in order to access the parking area.

    (3)

    A planter or landscaped area at least four feet wide (inside dimension) must be provided between a parking area and a public street or private drive, other than an access drive, that is adjacent to a parking area. Each parking area with more than five parking spaces must include landscaped areas that are equal in area to at least five percent of the area occupied by the paved parking area.

    (4)

    To provide visual and physical breaks and reduce traffic hazards to pedestrians, landscaped areas must be located between the parking area and each sidewalk adjacent to the parking area, except for any point at which a sidewalk intersects with the parking area.

    (5)

    For any parking space with an angle of parking of forty-five degrees or greater, in lieu of paving, a maximum of two feet of a standard parking space's depth, or one and one-half feet of a compact parking space's depth, may be planted with low-lying groundcover or landscaping to allow for up to a two-foot bumper overhang. A barrier curb or wheel stop measuring no more than five inches high, at least six inches wide, and thirty-six inches long must be provided in the parking space if the parking space is in front of a building, facility, or structure.

    (6)

    The following requirements apply to each parking area that includes more than seventy parking spaces:

    (A)

    Trees must be provided at a rate of at least one tree per twenty linear feet of landscaping. Each tree must measure at least five feet in height above-ground at the time that it is planted.

    (B)

    Planter islands must be provided at the ratio of at least one island for each ten parking spaces. Each planter island must be at least five feet wide and at least as long as the depth perpendicular to curb for the longest parking space adjacent to it.

    (C)

    Trees, or clusters of trees, must be evenly distributed throughout the parking area by locating trees along the perimeter of the parking area and within planter islands.

    (7)

    Each landscaped area must be continuously maintained to ensure it remains free of debris, litter, and weeds, and that landscaping remains healthy. To encourage water conservation, each parking area that includes landscaping must also include an automatic irrigation system that meets the requirements of this code pertaining to landscape irrigation and water conservation.

    (d)

    Tandem Parking. Two-car tandem parking spaces are permitted as specified in this section. Each tandem parking space must have a space width measuring at least eight feet and six inches, and a space depth perpendicular to curb measuring at least thirty-six feet. Vehicles using a tandem parking space must not block, or be allowed to overhang into, walkways or other pedestrian access areas, or any street or other public right of way. Each tandem parking space will be counted as two standard parking spaces toward the total amount of off-street parking spaces that must be provided under this chapter.

    (1)

    Single-family Residential. For any residential use located in a single-family residential (R-) zoning district, a tandem parking space is allowed, as long as the minimum setback requirements applicable to that zoning district are met.

    (2)

    Multiple-Family Residential. For any residential use located in a two-family (D-1) or multiple family residential (M-) zoning district, no more than fifteen percent of the residential units may be provided tandem parking spaces. A tandem parking space to serve an individual residential unit is allowed if the following requirements are met:

    (A)

    The tandem parking space is assigned to a single residential unit;

    (B)

    The tandem parking space is enclosed within a garage that allows ingress to and egress from a shared private road or a public street without requiring a vehicle to back out onto the road or street;

    (C)

    The multiple family residential use is located within the General Plan Transportation and Circulation Element Transit Corridor or Local Transit Service Area; and

    (D)

    The tandem parking space does not interfere with, or obstruct the use of, any other unit's assigned parking.

    (3)

    Commercial/Retail/Business. For any commercial, retail, or business use located in an O-1, A-O, C-B, N-B, R-B, C-, or P-1 zoning district, no more than twenty-five percent of the amount of off-street parking spaces required to be provided under this chapter may be tandem parking spaces. Tandem parking spaces are allowed if they are used in conjunction with a valet service that serves the land use during all hours of operation. No tandem parking space may be designated for self-parking, unless it is restricted for employee use.

    (e)

    Electric Vehicle Charging Spaces. Each EV charging space provided in a parking area counts as one space toward the minimum number of parking spaces required by this chapter. The following requirements apply to each EV charging space:

    (1)

    Each EV charging space must be accessible to persons with disabilities.

    (2)

    Each EV charging space must include a posted sign and painted curb, or ground markings, indicating that the space is exclusively for EV charging purposes.

    (3)

    EV charging equipment must be located so that pedestrians are not required to cross between the EV charging space and the EV charging equipment. The EV charging equipment may not obstruct any Americans with Disabilities Act-compliant sidewalk, entrance, curb-cut, or ramp, while in use or otherwise.

    (4)

    EV charging equipment must be illuminated by lighting to enable the equipment to be used at night.

    (5)

    Concrete-filled steel bollards or other similar barriers must be installed between EV charging equipment and an EV charging space if either of the following applies:

    (A)

    The EV charging equipment is located less than twenty-four inches away from the EV charging space that it serves; or

    (B)

    The EV charging equipment is located twenty-four inches or more away from the EV charging space that it serves and does not include, between the space and the equipment, a curb measuring at least six inches high.

    (6)

    An electric vehicle may occupy an EV charging space only while charging is in progress. Parking in an EV charging space when charging is not in progress is prohibited.

    (7)

    EV charging equipment must be maintained in working order at all times. The name and telephone number of the party responsible for maintaining and repairing the equipment must be posted on the equipment and updated as necessary.

    (f)

    Solar Energy Systems. Nothing in this chapter prohibits the installation of a solar energy system on or above a parking area, provided that the system otherwise meets the requirements of this code, and is located, installed, operated, and maintained in a manner that complies with all applicable federal, state, and county requirements.
