Principals, charter school leaders, real estate experts, special education advocates, and others will join together to try to untangle knotty matters involving school space, city officials announced Friday.

The joint City Hall-Department of Education working group, which the city first revealed last week, will tackle school co-locations, overcrowding, and classroom trailers, which lawmakers have urged the city to promptly remove. The 24-member group will recommend long-term solutions to reduce overcrowding, practical strategies for schools that must share space, and ways to ensure that schools have room for the arts and physical education, the City Hall press release said.

Mayor Bill de Blasio’s decision to block a few charter schools from moving into public buildings, while still allowing several others to do so, prompted Governor Andrew Cuomo and state lawmakers to enact a series of sweeping protections for charter schools. Hoping to stem any further fallout from his co-location decision, de Blasio has tried to make amends with charter-school supporters and formed the space-sharing group.

Led by schools Chancellor Carmen Fariña and Deputy Mayor Richard Buery, the City Hall-formed group follows several earlier education department initiatives to address space-sharing.
