PARK SLOPE - Education officials are mulling a new zoning proposal that could alter the public school landscape in Park Slope. The Department of Education (DOE) released a map of the plan, which would impact students at P.S. 321, P.S. 107, P.S. 39 and P.S. 10. Parents may be forced to send their children to different schools based on where their homes fall in the new zones. Under the plan, some schools would take in more students while others would lose them. However, the changes would only apply to students starting in a new school, not those already enrolled. In addition, DOE officials say a new school could also be created. The Community Education Council for District 15 is expected to vote on the proposal in November. If approved, it would go into effect for the 2013-2014 school year.
