On March 22, 2007 the Town Council directed the Town Manager to approach the School Board regarding the forming of a “subcommittee consisting of 2 members from the Town Council, 2 members from the School Board, 2 members from the Merrimack Village District and 3 members from the MYA to find and develop new ball fields in the Town of Merrimack”. The newly formed committee is called the Athletic Fields Needs Committee.
