Parking Lot Screening Requirements in Concord
In the City of Concord, all surface parking areas must be screened from streets and adjoining properties to enhance visual appeal and mitigate environmental impacts.

Perimeter Landscaping and Screening
All surface parking areas in the City of Concord must be screened from the street and adjoining properties. The open areas between the property line and the street right-of-way must be landscaped in accordance with the following requirements:
Adjacent to Streets
- Location: Parking, except for single-family dwelling or duplex units, shall not be located within the required setback areas, which must be landscaped.
- Screening Height: Landscaping must be designed and maintained to screen cars from view from the street to a minimum and maximum height of 30 to 36 inches [Section 18.165.060].
- Screening Materials: Acceptable materials include a combination of plant materials, earth berms, decorative fencing or walls, or raised planters.
- Shade Trees: Shade trees must be provided at a minimum rate of one tree for every 30 linear feet of landscaped area.
Adjacent to Side or Rear Property Lines
- Perimeter Strip: Parking areas for multifamily and nonresidential uses must provide a perimeter landscaped strip at least five feet wide (measured as an inside dimension) where the parking area adjoins a side or rear property line.
- Tree Requirement: Trees must be provided at the rate of one tree for each 30 linear feet of landscaped area [Section 18.165.060].
Adjacent to Residential Uses
- Landscape Buffer: Parking areas for nonresidential uses that adjoin residential uses must comply with the transitional requirements in Section 18.150.180. A five-foot-wide landscape buffer must be provided between the parking area and the common property line bordering the residential use to buffer glare, light, or nuisance noise.
