The state Bond Commission is slated to meet today.  There's funding on the agenda for grants including public safety, economic development and transportation.  New Fairfield would be awarded $484,000 to finance the creation of a multi-use trail that would run between the north side of Margerie Reservoir and Route 37 from Peck Road in Danbury to the center of New Fairfield.  A $635,000 grant is proposed for Bethel to use to expand Clarke Business Park.  The money would cover site construction costs for the development of little more than 17 acres and 4 new commercial lots.
