Members of the Schlumberger Citizen's Committee have suggested to the Ridgefield Board of Selectmen that $25,000 in contingency funding be spent on preliminary designs for an amphitheater.  The funding was approved for a traffic study and site plan of the town-owned 30 acre property.  The outdoor stage was one of the top uses residents backed in previous surveys of what to do with the land.  First Selectman Rudy Marconi told the Newstimes that the project, if approved, would be privately funded after designs have been drawn up.
