The J.A. Dempwolf-designed historic courthouse at 28 E. Market St. soon will undergo about $195,000 in waterproofing measures to stop leaks in three of four corners of the basement.

The 1898 building was rehabilitated and converted into county administrative offices after the York County Judicial Center was built.

The $18 million renovation was completed in 2006 and included about $1 million to repair and restore the main dome and cupolas that distinguish the building from afar, but little else was done to the exterior because it was in good condition at the time, said county facilities director Scott Cassel.

Water is entering during hard and prolonged rains, soaking parts of the county's elections and information services departments, he said. The leaks became pronounced during Tropical Storm Lee a couple of years ago and have gradually become worse, Cassel said.

The waterproofing project — including caulking, repointing and repairing joints — will go to bid around June. Cassel said he's hoping work will be complete by September.
