In order to provide for the efficient management of its duties and the fair hearing of items coming before it, the Planning Board may adopt and amend written rules governing the conduct of its meetings, provided such rules shall not conflict with this Ordinance or the provisions of any other Ordinance or Charter requirement. Such rules may include a provision that the Town Planner, in conjunction with the Planning Board Chair, may refuse to schedule an item for the Planning Board agenda unless and until the application in question is complete, including all Town staff reports. The Planning Board has the right to postpone a decision on an application to the Board if a significant amendment or additional information is proposed after the initial completed submission.
