To provide vehicle parking that satisfies local zoning requirements while minimizing the on-site space required to accommodate the required number of parking spaces. In addition, it discourages the design of parking lots larger than necessary.
CALGreen Code Section A5.106.6: Parking capacity.
Design parking capacity to meet but not exceed minimum local zoning requirements.
CALGreen Code Section A5.106.6.1: Reduce parking capacity.
With the approval of the enforcement authority, employ strategies to reduce on-site parking area by
1. Use of on street parking or compact spaces, illustrated on the site plan or
2. Implementation and documentation of programs that encourage occupants to carpool, ride share or use alternate transportation.
Note: Strategies for programs may be obtained from local Transportation Management Authorities (TMAs).
Intent:
The intent of these provisions is to provide vehicle parking that meets local zoning requirements but reduces the on-site area needed to accommodate the required number of parking spaces. Further, it discourages the design of parking beyond required quantities.
Compliance Method:
Indicate the location and configuration of parking spaces, including on-street parking and compact spaces or other approved strategies aimed at reducing site paving to a minimum. Plans may include a reference to the local TMA program that may be used to reduce parking demand. If a TMA program is cited, include it in the operation and maintenance manual for reference by future building occupants.
Enforcement:
Plan intake: The plan reviewer should confirm that the construction documents show that the required strategies have been incorporated in the site design for parking capacity requirements and local zoning ordinances.
On-site enforcement: The inspector should verify that the reduced parking capacity strategies shown in the design have been carried out in construction. He or she may check the operation and maintenance manual if TMA programs are recommended for compliance.
