 Once suffering from significant blight, The Pearl District has seen fervent restoration and new business development thanks to a concerted infill effort on the part of the City of Tulsa, including new bars and restaurants, white collar small offices and new residential buildings, with zoning designed to encourage mixed use and walkability.It is bordered by 1st street to the north and 11th street on the south, and lies adjacent to Centennial Park to the west.The Tulsa Fire Alarm Building at 1010 South Detroit, which has been unused for several years, is part of this district.
