Vance and Saint James, elementary schools would close, and a 900-student Holly Hill Elementary would be built to house students from all three schools, reports WLTX-TV.
Orangeburg Superintendent Shawn Foster said the new Holly Hill would cost between $40 million and $45 million. It would be built on the site of the existing football and baseball fields.
The district also plans to build a middle school wing on Lake Marion High School's campus.
The school board plans to put a $190 million bond request on the November ballot to pay for the facility upgrades.
