The New Fairifeld Board of Finance has rescheduled its final budget markup to May 5th.  Town officials are looking for more details about federal grant funding, and want to give residents more time to make their voices heard.  The proposed municipal budget is about $12.9 million, a nearly 5 percent increase, while the proposed Board of Ed budget is $45.4 million, almost a 4 percent increase over the current year.  If no changes are made, the mil rate would increase 3.6 percent.  New Fairfield officials attribute the hike to increased debt service for the two recent school projects.
