PPN Interview: Central Park Conservancy
At the ASLA 2018 Annual Meeting and EXPO, members of the Historic PPN were treated to an interview with Lane Addonizio, Affil. ASLA, and Chris Nolan, FASLA, of the Central Park Conservancy. The two shared experiences from their decades-long stewardship of America’s First Park, a calling that often involves negotiating a delicate balance between preservation and change.
