Vacant parcels near Waipahu's sugar-mill heritage sites and Waikele edges are subject to 30-day weed abatement notices under ROH Chapter 16A public nuisance rules.
Waipahu has scattered vacant parcels along old plantation roadways and between residential areas and the Waikele Stream corridor. Tall guinea grass and haole koa can become fire fuel during summer Kona winds and can obstruct narrow sidewalks in the old core. Under ROH Chapter 16A (formerly Chapter 41, Article 10), weeds are defined as vegetation that creates fire hazard, breeds vermin, impedes roads or sidewalks, or obstructs waterways. Property owners receive a 30-day notice to cut or remove. If unaddressed, the city may enter and abate the nuisance at the owner's expense, collectable as a lien.
Failure to abate within 30 days authorizes city entry and removal; owners are billed for costs, which can attach as a lien if not paid timely.
