Notes: Parking and Getting Around on Campus

1. We are no longer allowed to distribute free daily parking scratch-off cards. Visitors may park in any designated visitor/pay zones (marked with a green P) and use credit cards to purchase visitor permits valid at the meters for up to 8 hours (parking is free before 08:00 and after 16:00). The cost is $1.50 per hour. There are visitor spaces on the ground level of the parking structure at the corner of Via Ortega and Panama Street. We can sell daily A permits, which cost $12, and allow parking in more spaces, and daily C permits, basically hunting licenses, for $4.50.
2. There is major construction going on which may significantly affect pedestrian access to the Astrophysics building where the meeting is being held, and our offices in Cedar and Cypress. In particular, Via Ortega, the road in front of Cedar and Cypress, is closed from the parking structure to Via Pueblo, along with the former parking area in front of those buildings. There is also construction going on along Via Pueblo. The best route from the parking structure and the offices in Cedar/Cypress is through the arcades around Y2E2 (the Yang & Yamazaki Environment & Energy Building).
