The Gainesville City Council gave the last word Tuesday on controversial plans to redevelop the Lanier Plaza shopping center on Thompson Bridge Road. By a 4-1 vote, the council approved a rezoning of the shopping center and sent a few dozen residents exiting the municipal courtroom in disappointment after their protracted efforts to stop the redevelopment from proceeding failed. Polestar LLC, a subsidiary of Tennessee-based developer Hutton, plans to demolish the existing shopping center and build a 42,000-square-foot grocery store and an accompanying 12-pump fueling station.
