Which statement is true regarding Class I membership on planning boards?

The statement regarding Class I membership on planning boards being filled by the mayor or city manager is accurate. In New Jersey, Class I members of a planning board are indeed designated to be the mayor or, if applicable, the city manager. This ensures that the highest level of municipal leadership is directly involved in planning decisions, providing insights into the local government priorities and aligning the board's goals with the overall community objectives.

The other statements do not accurately reflect the structure and rules governing planning board memberships in New Jersey. Class II membership does include elected officials, but it is not restricted exclusively to them, as it can also encompass certain appointed officials. Class III membership is indeed comprised of municipal employees, however, they are not the only individuals represented on planning boards; there are other classes that may also include various stakeholders. Lastly, requiring that all members hold no other municipal office is incorrect, as it is specifically the Class I member who must be the mayor or city manager, but other classes may include individuals with different municipal roles.
