Here is an interactive map that will get you to the Engineering Center, the building in which the Department is housed. You should also be able to get detailed directions here from almost anywhere. The Computer Science Department is located in the Engineering Center, which is on the southwest corner of Colorado Avenue and Regent Drive. Most of the parking on campus is by permit, although there is visitor parking scattered about. That nearest the Engineering Center is on the east side of Regent, between the Coors Events Center and a large parking structure.
