Mililani Town property owners cannot remove registered exceptional trees without a Parks and Recreation permit under ROH Chapter 40, Article 8.
Mililani Town is newer than many Oahu neighborhoods, but some original monkeypod and banyan trees from preserved Del Monte pineapple-era landscapes are designated on the Oahu Exceptional Tree Register. ROH Chapter 40, Article 8 prohibits removal or destruction of listed exceptional trees without a permit from the Department of Parks and Recreation. Emergency removals for imminent hazards are allowed under Sec. 40-8.9 but require documentation. Street trees have a separate permit track under ROH Sec. 10-1.4. Homeowners planning ADUs or pool additions in Mililani Mauka should verify no exceptional tree sits within the build footprint before design, because protected trees can force redesign or outright denial.
Unpermitted removal can trigger fines, mandatory replacement plantings, and misdemeanor prosecution for repeat offenders under Chapter 40.
