Princeton Academy is a private boys’ school for grades K-8 that was founded in 1998. Currently, students at the school play soccer, lacrosse and baseball, participate in physical education classes, and enjoy recess playtime on two grass fields. The proposed turf project would convert the existing grass athletic fields in the northeast corner of Princeton Academy’s campus into turf fields. The turf fields would primarily be for soccer, lacrosse, and baseball. The Princeton Soccer Association would lease the turf fields, using them on weekdays from 6 to 9:30 p.m. and on weekends until 7 p.m. At the planning board’s public virtual meeting on Dec. 10, about 100 people were on Zoom for the public hearing on the academy’s proposed fields, but the board reviewed another project first, and that review took three hours, leaving only half an hour for the review of the school’s application.
