I would think that there aren’t many schools at all that would be worth the extra cost compared to UMD. Maybe somewhere such as MIT, Caltech, Georgie Tech, or Stanford. Even then it would probably depend upon how many years of additional studying you would need (which depends on how many credits you will get), and how much pain would be caused by the extra cost.
UMD is a very good school. According to their web site their Civil Engineering degree is ABET accredited, which is not a surprise.
I would be very tempted to finish your bachelor’s at UMD, and then think about other schools if you want to go for a master’s. Some students do work for a year or two between a bachelor’s and a master’s.
