A public hearing has been held in Bethel on work for a turf field in the school campus.  Claris Construction representative Mike Kozlowski told the Board of Selectmen that they're taking the existing field between the high school and the middle school and converting it into an artificial turf field.  With additional square footage by moving the baseball field back into the hillside, and moving softball field, the town will get a full regulation lacrosse, soccer and field hockey field.  Kozlowski says properly maintained, the field will have a 12 to 15 year lifespan.  He notes that there is no need for irrigation and the gravel around the field will act as a giant filter.  A private donor, who asked to remain anonymous, offered to fund the Benzing Field replacement.  A four-post lighting system has been proposed to illuminate the area where soccer, lacrosse and field hockey are played.
