It depends on what you want to do with your career and how much more you project.
D1- Maybe, for a small D1 school probably need to be at least 86-89 range by senior year, probably 82-84 as a sophomore
D2- Likely, excluding the top 10-15 D2 schools in the nation (which tend to be better than a good handful of D1 schools), you need to be around 84-87 range by senior year, probably 80-82 as a sophomore
D3- Definetly, most D3 pitchers throw in the 81-85 mph range by senior year, probably upper 70's by sophomore year.
THE #1 THING IS COMMAND, MECHANICS, AND OFF SPEED, NONE OF THESE VELOCITIES APPLY TO SOMEONE WHO CAN'T CONTROL IT. I'VE SEEN PITCHERS THROW MID 80'S WITH NO CONTROL WHO CAN'T FIND A D3 SCHOOL AND PITCHERS WITH EXCELLENT CONTROL IN THE 79-82 RANGE GO D3.
