There are a number of public paid parking lots on or near campus (see map below). Note that some lots are for permit parking only. Hourly and daily lot rates range from as little as $1 per hour to $7 for all day.
Street parking on Pacific Avenue and around campus is $0.75 per hour and limited to 90 minutes. The Link light rail also stops right at 19th and Pacific, so you can park elsewhere in town and ride the train for free.
From Interstate 5 take the I-705/Tacoma City Center exit (exit 133). From I-705 take the South 21st Street exit. Turn left at the traffic light onto 21st Street. Go through the light at Pacific Avenue and the campus will be on your right.
