BETHEL — The public is set to discuss proposals on selectmen terms, budget approvals and other possible changes to the charter at a meeting on Tuesday evening.

The Charter Revision Commission has recommended 21 changes to town rules, including requiring the town to complete construction plans for major projects before going to referendum.

The most controversial idea is one the commission did not suggest: to extend terms for the Board of Selectmen from two years to four.

Residents could eventually vote on charter changes in the polls.

The public hearing is at 7 p.m. Tuesday in Meeting Room A of the municipal center.
