RICHMOND, Va. -- Two entertainment venues on the table for Richmond were given the City Council’s endorsement at its meeting Monday night, one of them two years after voters narrowly rejected it. Councilmembers unanimously approved a performance grant agreement for the planned Richmond Amphitheater on the riverfront near Tredegar, and almost unanimously approved ordinances authorizing agreements that set the stage for a potential second referendum in November on Urban One’s proposed casino in South Richmond.
