No Adverse Impact (NAI) is a forward-thinking, fair, and legally defensible approach to coastal land management. It was first articulated by the Association of State Floodplain Managers. In its broadest sense, it is a set of "do no harm" principles that communities can use when planning, designing, and evaluating public and private projects. By following the NAI approach, communities can protect people, property, and municipal budgets.
