As Round Rock continues to grow, Round Rock ISD is looking at proposals for a sixth high school.

Currently, there are more than 3,200 students enrolled at Round Rock High School. If overcrowding isn't addressed, the school could have more than 4,000 students on the campus by 2021.

"Our community has asked for smaller high schools, high schools that are below, at 2,600 or below," said district spokesman Corey Ryan. "Currently none of our high schools meet that criteria."

Seven years ago, Round Rock ISD bought a 182-acre tract of land along Pearson Ranch Road. That land could be turned into a three-story high school that would serve up to 2,600 students. This high school would be built to primarily relieve overcrowding at Round Rock High.

The district used $15 million of surplus money from past bonds to create a schematic design of what the new campus would look like. A new bond election would be needed to get the school built.

"The high school 6 design is $130 million for the school and an additional $20 million as of right now if they add an auditorium," Ryan said.

Construction on the new high school could start as early as August 2017.

A citizens bond committee is looking at a possible 2017 bond package to fund the new school and more projects in the district.
