Parking Standards for Business Park and Industrial Districts in Concord
In Concord, off-street parking requirements for Business Park and Industrial Districts are determined by the specific land use classification, typically calculated based on floor area or number of employees. Most uses must provide parking on-site, with specific standards for dimension, layout, and circulation to ensure safe and adequate access.
Parking Requirements by Land Use
The number of off-street parking spaces for industrial and business park uses is generally dictated by the building's gross floor area or the number of employees on the largest shift. The following table summarizes the parking requirements for key industrial uses as defined in the Concord Development Code.
| Land Use Type | Parking Spaces Required |
|---|---|
| Construction Equipment/Large Vehicle Sales | 1 space/250 sf gross floor area; plus 1 space/2,500 sf outdoor sales/storage area |
| Fleet-Based Service | 1 space/250 sf gross floor area; plus 1 space/fleet vehicle |
| Freight and Truck Terminal | 1 space/2 employees on max shift, or 1 space/1,500 sf gross floor area (whichever is greater) |
| Towing | As determined by use permit |
| Artisan/Custom Product Manufacturing | 1 space/250 sf office area; 1 space/1,000 sf gross floor area (excluding office) |
| Research and Development | 1 space/750 sf gross floor area |
| Storage | 1 space/500 sf gross floor area |
Design and Access Standards
All parking facilities for industrial uses must adhere to strict design standards to ensure safety and functionality:
- Standard Stall Dimensions: Standard parking spaces must be a minimum of nine feet wide by 19 feet long. Parallel spaces must be at least nine feet wide by 24 feet long [Section 18.160.090].
- Compact Spaces: On sites with at least 10 parking spaces, up to 25 percent of the total may be compact spaces (eight feet by 16 feet), provided they are dispersed and designated with pavement markings [Section 18.160.090].
- Driveway Widths: Driveways serving industrial uses must comply with the widths defined in the code. For nonresidential uses, a two-way driveway serving 25 or more spaces requires a 30-foot width [Section 18.160.110].
- Circulation: Parking areas must be designed so vehicles can exit to a street in a forward direction. Stacking areas of at least 20 feet are required for lots with 20 or more spaces to prevent driveway intersection conflicts [Section 18.160.090].
- Parking Lot Landscaping: A minimum of 10 percent of the gross parking lot area must be landscaped. Shade trees must be provided to achieve 50 percent shading of the pavement within 10 years [Section 18.165.060].
- Maintenance: Parking lots must be permanently maintained in a dust-free, clean condition, free of refuse and debris [Section 18.160.090].
Adjustments and Exceptions
The Planning Division may allow adjustments to these parking requirements under specific circumstances:
- Shared Parking: Adjacent nonresidential uses with distinct peak demand hours may apply for a minor use permit to share on-site parking [Section 18.160.050].
- Off-Site Parking: Required parking may be located in a shared facility up to 300 feet from the site, subject to a recorded parking agreement [Section 18.160.050].
- Electric Vehicle/Alternative Fuel: Parking requirements may be exceeded to accommodate charging or fueling stations for electric or alternative fuel vehicles [Section 18.160.030].
