How can I stay at my current high school?

I live in Illinois. We want to move into a cheaper house to save money and have my grandmother move in with us. This new house is JUST outside the border of my current school's zone. I don't want to go to the school that's assigned, because there are lots of druggies and everyone I know hates that school. I'm going into my junior year of high school, and it would be so hard for me to leave. I already have so many teacher's willing to help with ACT prep and everything. Is there anyway I could stay at my current high school? Like I said, the new house is JUST on the border of my school and the other school.
