Saying school officials must formally vote on whether or not to lend a strip of Saxe property for large vehicles accessing a proposed construction site behind the New Canaan YMCA, the Planning and Zoning Commission on Tuesday approved the Y’s application for a special permit to expand. Forcing the Board of Education to take a definitive stance is one of 33 conditions that P&Z imposed on the closely monitored expansion project. “I have a lot of good friends on the Board of Education, but quite frankly they took the easy way out by narrowly defining what their mission is in this town,” P&Z member John Goodwin said at Tuesday’s meeting, held before about 40 people gathered in the Sturgess Room of the New Canaan Nature Center’s Visitors Center. “The YMCA provides a good number of educational programs, just like education system does. It’s been very clearly stated that, effectively, the YMCA is an extension of the school system—at a minimum, because they provide a venue for our swim meets.
