The Area of Potential Effects is a geographic area where an undertaking may directly or indirectly cause alterations of historic properties, if any such properties exist. Proposed alignments, adapted from the Maui County's Pali to Puamana Plan, converge at serval points in two distinct areas, where the alignments differ from one another, Olowalu and Ukumehame.
The preferred alternative was selected from two differing proposed alternatives one in each of the two differing areas.
