Trees in Mililani Town designated under ROH Chapter 40 Article 8 as Exceptional cannot be removed without City Council approval, and alteration needs a permit from the Department of Parks and Recreation.
The Exceptional Tree Ordinance, codified at ROH Chapter 40 Article 8, protects trees of historic, cultural, or botanical significance across Oahu. While Mililani Town is a younger master-planned community, mature monkeypods, kukui, and other specimens may qualify. Removal requires prior City Council resolution; alteration such as crown reduction requires a DPR arborist permit. Section 40-8.9 provides an emergency-hazard exception requiring city notification. HOA covenants typically require coordination with the Exceptional Tree process before any work begins on listed trees.
Misdemeanor penalties up to $10,000 per tree, restoration orders, and HOA covenant fines layered on top.
