The Newtown Board of Selectmen has approved the final design contract for the Sandy Hook Permanent Memorial.  Public Building & Site Commission Chairman Robert Mitchell told the Newtown Bee that the project will be completed by December 2022, the 10 year anniversary of the shooting in which 20 children and 6 educators were killed.  Award-winning Newtown landscape design architect Tara Vincenta has been authorized to serve as the local associate on the project.  San Francisco-based SWA Group will continue to oversee the project.  Vincenta is principal and founder of Artemis Landscape Architects, and has 30 years of experience ranging from environmental and regional planning studies, to multi-family housing, corporate, and institutional work.  Mitchell told the Bee he will be prioritizing Connecticut-based construction mangers in his Requests for Qualifications.  That person would be in charge of pre-construction work, cost estimating, and review of materials.
