The long-awaited Eastside parking structure, some 600 spaces strong, quietly opened last week with a new name: 10 Parking Structure.

“I understand it’s named after the parking lot number on which the structure (and the almost-finished California NanoSystems Institute) now stands,” explained Bob Sundberg, associate director of Transportation and Parking Services.

The new, $16.4-million structure, formerly referred to as Parking Structure 2, has its main entrance on Mesa Road where traffic signal lights are now operational. Two pay stations are inside. It is designated as faculty and staff parking Monday through Friday, from 7:30 a.m. to 5 p.m.

Graduate and undergraduate students, and visitors, with valid permits may use the 10 Parking Structure’s spaces after 5 p.m. and during weekends. Also, 40 of the parking spaces on the ground level have been designated for coastal access use, as required by the California Coastal Commission.
