Superintendent Reginald Lawrence says one of the key improvements will be a secure entrance to limit access to the school.
"When crises arise in today's day and time when so many things are happening, that secure entry way at least gives school districts the opportunity and time to be prepared for what comes next. So we get to control those who come in, where they get a chance to go, and it keeps our staff and students safe."
The expansion will add about 38,000 square feet to the building.
One of the additions to the high school will be a commons area for students.
"I like to call it a college commons sort of atmosphere. You know our students are here from 6 am to 9 pm some days, so there'll be a new commons area for them to learn, to rest, relax, and get work done."
Also included will be a renovation of the cafeteria, new classrooms, moving administrative offices to the new entrance, and an improved area along 25th Avenue for student drop off and pick up.
The work is scheduled to be done by late next year.
