ZBA time frames under a 40B application

Norma Cronin, the town’s stellar staff person for the Planning Board and the Zoning Board of Appeals, informed me that I had made an error in the timing for 40B projects before the ZBA.  The ZBA has to convene a hearing within 30 days of its receipt of an application for a comprehensive permit under Massachusetts General Laws c. 40B, and has to render a decision within 40 days after the closing of the hearing.  I had cited the usual ZBA time limits of 65 days to hold a hearing and 90 days to make a decision, but 40B has its own accelerated schedule.
