Piles of debris around the southwest corner of Manchester and McKnight in Rock Hill attest to the demolition underway there.

The former city hall building is one of the last remaining structures to be razed to make way for Market at McKnight.

According to Pete Sebelski, project manager, demolition of city hall should begin on Aug. 24 or 25. Demolition permits are in hand and the cell tower and water easement issues have been resolved, he reported at Tuesday’s Rock Hill Board of Aldermen meeting.

However, the $12.6 million tax increment financing costs have now increased to $13.8 million. Last month the board OK’d an additional $510,000 to move the cell tower located at city hall. An additional $700,000 is now needed to make up for the loss of Brownfield credits. The TIF commission will need to approve this latest addition. Brownfield credits are tax credits available for clean up and redevelopment for asbestos and soil contamination.

Soil contamination was found at the Windshield Doctor site formerly occupied by a filling station, according to City Administrator George Liyeos. He said asbestos was uncovered at some of the houses and businesses. A miscommunication between the consulting firm and Novus led to the failure to get the credits.
