Reeves Young is the contractor the city hired last year for $7.6 million to build the fields, plus several other amenities and renovations to the park. A city spokesperson said Reeves Young was aware there may be buried materials from the old hospital, which housed patients with physical and mental disabilities for about 30 years before being closed in 1997. DeKalb County tore down the building around 2007, before Dunwoody was incorporated. “Reeves Young knew there was a possibility they would hit the old foundations from the hospital, but there was no guarantee either way,” said city spokesperson Jennifer Boettcher. A survey was conducted, she added, but there was no way to know what was buried until excavation began.
