Design plans for Warren County Jail expansion received initial approval from county officials on Friday. Upland Design Group architect Allen Hill, who presented preliminary drawings to members of the county Building and Grounds Committee and county Corrections Partnership Committee, said bid documents should be ready in early July and project completion is slated for January 2019.“Looking at the site, we felt the best area for expansion was at the end of the building because there’s an existing corridor,” said Hill. “By extending that corridor out, we felt that was the most cost-effective way to add onto the facility.”
