The bill S.255 establishes a pilot Windham County Law Enforcement Governance Council aimed at providing regional law enforcement and related public safety services. It defines key terms such as "member municipality," which refers to those municipalities that choose to participate in the Council, and "nonmember municipality," which refers to those that do not. The Council will be formed when five or more eligible municipalities vote to join, with operations commencing on July 1, 2026, or upon the formation of the Council, whichever is later. Each member municipality will have one representative on the Council, responsible for voting and receiving services, and will be required to pay a proportionate share of costs through a county tax mechanism.

The Council will have governance powers, including the ability to adopt bylaws, determine budgets, and establish service levels. It will be responsible for delivering law enforcement services through the Windham County Sheriff's Department and will submit annual reports on its operations and evaluations of the pilot program. Nonmember municipalities will not incur costs related to the Council's operations and will retain their rights to establish independent law enforcement services. The Council is set to dissolve on June 30, 2034, or earlier if the number of member municipalities drops to one, with remaining funds returned to municipalities based on population.
