Bethel residents have set a budget referendum date of April 11th.  The proposal includes $29.8 million on the municipal side and $45.1 million for the schools.  It's a 2.8 percent spending increase, bumping up the mill rate by .48 percent.  The $2.3 million capital budget does still include $979,000 for a turf field, which some residents tried to have removed during a town meeting.  This comes as the police station construction is $889,000 over budget.  Plans call for the firing range to be left incomplete and new furniture purchases halted if more money isn't allocated.
