Part of the New Fairfield budget proposed for the coming fiscal year includes money for overnight emergency medical staff.  The Newstimes reports that the fire department needs paid staff to help at night because of a shortage of volunteers and an increased number of calls.  Paid staff works during the day and on some weekends.  The proposal to add overnight coverage is $145,000.  The New Fairfield budget this year is $13 million, school spending is requested at $43.4 million.  The proposed budget represents a tax rate increase of 3.37 percent.  The New Fairfield Board of Finance is holding a budget meeting tomorrow night.
