Well-used and active public spaces are increasingly vulnerable to a variety of threats as seen in New York, Berlin, Nice, London, and Boston. To address these threats, cities must take a fresh look at their parks, plazas, and squares to ensure that they remain safe and enjoyable. A panel of design professionals, academics, and security experts discussed these new approaches and what they mean for public spaces in our cities. The National Capital Planning Commission, in partnership with the American Society of Landscape Architects, presented the event. Panel: • Jess Zimbabwe, Principal, Plot Strategies; Professor of Urban and Regional Planning, Georgetown University (moderator) • Susan Silberberg, Managing Director, CivicMoxie, LLC; former Lecturer, Massachusetts Institute of Technology • Richard Cline, Principal Deputy Director, Federal Protective Service, U.S. Department of Homeland Security • Gary Hilderbrand, FASLA, FAAR, Principal, Reed Hilderbrand LLC; Professor, Harvard Graduate School of Design
