I m graduate student here in CSUF but mine is electrical engineering. I know few people in civil engineering but as i told u, the best person to talk with is Professor Tiwari. He might help you out regarding in-state tuition and everythingelse. 
Before u make any decision let me tell u the truth
-fee hikes up almost every semester due to budget cut
-living expense is so high (1 bed room cost around 1000, as a paying guest  around 500)
-hard to find roommate unless u feel good sharing room with indians
-u feel like heaven if u consider weather  n offcourse u'll get a chance to hang up with hollywood celebs in malibu n venice beach
I m not trying to scare you, just telling u the truth. Talk to the department, they might provide you tuition waiver.
