Section 10.192.050 Parking Lot Design Standards

A.    Design Dimensions

Parking lots shall be designed consistent with the standards and the minimum dimension requirements contained in table:


ANGLE    W    L    B    C    D    E    F     G    H
90B         9.0    20.0    9.0        25.0    25.0    61.0    61.0    5.0

45B        9.0    20.0    12.7    19.1    15.0    24.0    50.2    62.2    5.0

60B        9.0    20.0    10.4    20.0    15.0    24.0    58.0    64.0    5.0

30B        8.5    20.0    17.0    16.5    15.0    24.0    45.0    57.0    5.0

PARALLEL    8.0    22.0    -    -    15.0    24.0    28.0    40.0    5.0


W= Stall width
L= Stall length
B= Stall separation of angled parking
C= Horizontal depth of angled parking
D= Aisle width (one-way)
E= Aisle width (two-way)
F= Overall frame width for parking plus driveway (one-way)
G= Overall frame width for parking plus driveway (two-way)
H= landscape planter setback (includes raised curbing)

Note:  The figures in the table above correspond to the dimensions shown in the parking diagram above.  For example “W” in the table corresponds to the width of an individual parking space. The table shows that for lots with 90°, 45°, and 60° parking, this measurement is 9 feet.  As another example, dimension “D” is the aisle width.  For a parking lot with 60• angle parking and one-way circulation, this measurement is 12.0 feet, minimum.

B.        Circulation

    Parking lots shall be designed so that backing onto public streets is precluded.  This standard does not apply to single family homes.

C.    Paving, Slope and Drainage

    All parking lots and driveways shall be surfaced with a minimum thickness of 2 inches of asphalt concrete, concrete or other material acceptable to the City Engineer, over a minimum thickness of four inches of an aggregate base material.   Parking lots shall be designed to facilitate proper drainage and shall not drain over any sidewalk or adjacent property.

D.    Curbing and Wheel Stops

    Concrete curbing at least six inches tall and six inches wide shall be provided around all perimeter areas and around all landscape areas to define the edges of the parking lot and to protect landscaping.  Wheel stops are required to protect buildings and walkways.

E.    Striping

    Parking spaces shall be clearly marked with paint striping a minimum of 4 inches in width.  Double striping is recommended, although single striping is acceptable.  Other markings and signage shall be provided to show circulation patterns.

F.    Lighting.

    Parking areas shall have lighting capable of providing adequate illumination for security and safety.  Lighting standards shall be in scale with the height and use of the structure. Lighting shall be   installed so as not to cause a nuisance to adjoining properties.

G.    Driveways for Commercial/Indsutrial/Municipal Family Residential Uses

1.    Minimum width:
    One way circulation:  15 feet
    Two-way circulation:  25 feet

2.    Location:
        The location of driveways to and from the public right-of-way shall be determined by the Planning and Building Director.  For corner lots, driveways shall be no closer than 5 feet to the street radius.   (see commercial district design standards for specific driveways locations for commercial properties Section  10.60, section H).

H.    Landscaping

    All parking lots shall be landscaped in accordance with the requirements contained in 10.196:  Landscaping.

I.    Parking Lot Location

    Parking lots shall be located on the same site or within 300 feet of the business to which the parking pertains except for uses in the Downtown Commercial (D) district.

J.        Shared On-Site Parking Reduction

    Where two or more non-residential uses share a single parking lot, the total number of parking spaces may be reduced by the Planning Commission in accordance with the following schedule:

        a.    A five percent reduction in the total number of parking spaces where the building square footage exceeds 50,000.

        b.    A ten percent reduction in the total number of parking spaces where the building square footage exceeds 100,000.

          c.    A fifteen percent reduction in the total number of parking spaces where the building square footage exceed 150,000.

        d.    A twenty percent reduction in the total number of parking spaces where the building square footage exceeds 200,000.

e.    Reductions greater than twenty percent are prohibited unless a variance is approved pursuant to Section 10.128 (Variances).

K.    Shared Off-Site Parking Agreement

    Where two nearby uses have distinct and differing peak parking demands (for example, a use that operates only during the day and a use that operates only at night) or where it can be demonstrated that one site has an excess supply of parking spaces that will not be used in the foreseeable future, the required number of parking spaces may be reduced through Minor Deviation, provided that the parking lots of each use are located within 300 feet of each other (as measured along the most direct pedestrian path).  The amount of reduction may be up to 75 percent of the amount of spaces required for the most intensive of the two uses sharing the parking.

L.    Planning and Building Director Modification

Parking space requirements of this chapter may be modified through Minor Deviation approval based upon specific findings that the characteristics of a use or its immediate vicinity do not necessitate the number of parking spaces required, and that reduced parking will be adequate to accommodate all parking needs generated by the use.  To grant a modification, the Planning and Building Director must make the following findings:

1.    That neither present nor anticipated future traffic volumes generated by the use of the site in the vicinity reasonably require strict or literal interpretation and enforcement of the specified regulation.

2.    That the granting of the variance will not create a safety hazard or loading of vehicles on public streets in such a manner as to interfere with the free flow of traffic on the streets.

3.    That the granting of the variance will not create a safety hazard or any other condition inconsistent with the objectives of this title.

M.    Bicycle Racks

Lots with 40 or more spaces may substitute a bicycle rack providing space for at least five bicycles at a ratio of one bicycle rack for each 40 spaces.  One parking space may be subtracted for each five-space bicycle rack.

N.    Handicapped Parking

Handicapped parking spaces shall be provided and designed per requirements contained in the California Building Code.

O.    Tandem Spaces

    Tandem parking spaces are prohibited.
