Neighborhood Center Flex (NC-Flex) Off-Street Parking Standards

In the Grass Valley Neighborhood Center Flex (NC-Flex) district, off-street parking requirements are determined by the floor level and the size of the use, with a significant exemption for ground-floor commercial spaces smaller than 3,000 square feet. Residential developments within the NC-Flex district generally require one space per unit, while larger commercial uses on the ground floor must provide one space per 500 square feet. All parking facilities in this district must be set back at least 20 feet from the front property line and are restricted to a maximum drive width of 15 feet.

Required Parking Ratios

The Grass Valley Development Code establishes specific parking ratios for the NC-Flex district that differ from the general citywide requirements. Because the NC-Flex zone is a Traditional Community Development Zone, these standards emphasize a pedestrian-oriented environment by reducing or eliminating parking for smaller storefronts [Section 17.21.060].

Location and Use Type	Minimum Parking Spaces Required
Ground Floor Uses
Residential Use	1 space per unit (0.5 space per studio)
Non-Residential Uses < 3,000 sq. ft.	No off-street parking required
Non-Residential Uses > 3,000 sq. ft.	1 space per 500 sq. ft.
Upper Floor(s) Uses
Residential Uses	1 space per unit (0.5 space per studio)
Other Uses (Office/Service/Retail)	1 space per 300 sq. ft.

Parking Location and Setbacks

To maintain the intended aesthetic of the Neighborhood Center Flex district, the Grass Valley Development Code regulates the placement of parking lots in relation to property lines. These setbacks ensure that vehicles are not the dominant visual feature of the streetscape [Section 17.21.060].

Property Line Boundary	Required Parking Setback (Distance from Line)
Front Setback	20 feet
Side Setback	0 feet
Side Street Setback	5 feet
Rear Setback	5 feet

Access and Driveway Standards

The NC-Flex district limits the impact of vehicle access points on pedestrian safety and sidewalk continuity.

Driveway Width: The maximum width for a parking drive is 15 feet, unless a larger width is specifically required by the Grass Valley Fire Department [Section 17.21.060].
Primary Street Restrictions: On corner lots, the primary parking drive cannot be located on the primary street.
Curb Cut Minimization: The Grass Valley Development Code encourages shared drives between adjacent lots to minimize the number of curb cuts along the street [Section 17.21.060].

Shared and Off-Site Parking

Recognizing the compact nature of the NC-Flex district, Grass Valley allows for flexibility in how parking requirements are met:

Off-Site Allowance: Required parking may be provided off-site within 1,300 feet of the project [Section 17.21.060].
Shared Parking: Parking requirements may be fulfilled through shared parking arrangements with adjacent or nearby properties.
Bicycle Substitution: Non-residential developments may substitute bicycle spaces for required vehicle spaces at a rate of eight bicycle spaces for one vehicle space, up to a maximum of 10% of the total required vehicle spaces [Section 17.36.060].
Motorcycle Substitution: For non-residential projects, motorcycle spaces may be substituted for auto spaces at a rate of one motorcycle space per 25 auto spaces, up to 10% of the total requirement [Section 17.36.070].

Design and Development Standards

All parking areas in the NC-Flex district must adhere to the following design specifications:

Space Dimensions: Standard parking spaces must be 9 feet wide by 18 feet long. If a space is adjacent to a column, wall, or fence, the width must be increased by at least one foot [Table 3-4 and Section 17.36.090].
Surfacing: All parking areas and maneuvering aisles must be surfaced with at least two inches of asphaltic concrete or three and one-half inches of Portland cement concrete [Section 17.36.090].
Landscaping: Any required parking area with more than six spaces must be landscaped. Multifamily, commercial, and industrial uses must provide landscaping for at least 10% of the gross area of the parking lot [Section 17.34.030].
