Parking space is not guaranteed. The management and assignment of parking zones is designed to provide a parking space to each permit holder. However, uncontrolled access to parking areas and unexpected parking demand make it impossible to guarantee a parking space in a permit holder's purchased zone. Every effort is made via surveys and limits on permit sales, to ensure that permit holders are not displaced from their purchased zones. Parking zones are color-coded with respect to their price. Permit holders must park in their color-coded zone as described below.

(1) Orange permits. Orange permit holders may park in either orange or green zones.

(2) Green permits. Green permit holders must park in green zones only.
