The Bethel Board of Finance is scheduled to meet tonight about proposed renovations to Rockwell Elementary and Johnson School.  The $68-million project is eligible for state grant reimbursement of about 45-percent.  But the state's financial situation has some people concerned.  A town meeting and referendum on the proposal still needs to be held and could be written in a way that accounts for the town not receiving grant money. Tonight's meeting is at 7 pm in Meeting Room A of Town Hall.
