Parking Supply Management

General Description:

Parking Supply Management involves creating additional parking facilities or modifying current facilities to increase capacity in order to accommodate more vehicles.  However, creating additional parking is often at odds with goals of conservation and preservation.

Effects of Solution:

¨ Increase Passenger Throughput

þ Increase Capacity (Create more parking for visitors)

¨ Manage System Efficiency

¨ Reduce Local Demand

By adding additional parking, demand can be spread from existing facilities to the new facility.  Please see the Parking Demand Management Fact Sheet for more information on shifting demand and other parking strategies.

Examples of Implementation:

Santa Monica Mountains National Recreation Area.
