SYCAMORE – The DeKalb County Board approved designs for an expanded jail and shut down a tourist park Wednesday.

Dennis Kimme, president of criminal justice planning/designing firm Kimme and Associates, gave board members an update on the jail expansion project, which could cost anywhere between $26.9 million and $31.7 million depending on how much immediate expansion the county wants.

The proposed design would increase occupancy by 163 on the low end and 221 on the high end. The existing public safety building would be expanded east and close the north half of the 100 block of North Locust Street.
