Hall County is looking to purchase more than 21 acres behind the Harrison Square public housing complex on the south side of Gainesville to develop a park and community center for the largely minority residents who call the area home. It is seen as a first step in a larger effort to bring economic development and commercial enterprise to the surrounding neighborhoods. The project has been in the works for a dozen years, beginning in 2004 when plans were drawn up to develop affordable housing on the site adjacent to Harrison Drive, Athens Street and Interstate 985.
