And there it goes. The Seneca Nation of Indians will be breaking ground and breaking bricks this week. Demolition of the distinctive H-O Oats complex on Perry Street will begin Thursday according to the Buffalo News. While the complex comes down, future plans for the property remain unclear. The Seneca Nation is negotiating with the NFTA to locate the casino in the former DL&W Terminalis second floor. The H-O site was a portion of nine acres purchased for either a back-up casino location or for parking and warehousing. According to the gambling compact with New York State, the Senecas must begin work on the casino before December 9.
