Pearl City lot coverage follows ROH 21-3.70-1, capping impervious surface at 75 percent for dwellings permitted after May 1, 2019, including homes in Waimalu, Manana, and Pearl City Highlands.
ROH/LUO Sec. 21-3.70-1 sets residential district standards including the 75 percent impervious-surface cap for dwellings permitted after May 1, 2019. In Pearl City's flat Waimalu and Manana blocks and hillside Pearl City Highlands parcels, the cap limits expansion of driveways, patios, and pool decks that would stress drainage infrastructure flowing toward Waimalu Stream and Pearl Harbor. Pre-2019 homes may exceed the cap as legally nonconforming but lose that status during substantial redevelopment. DPP often requires stormwater BMPs for projects close to the threshold. Permeable pavers and tree canopy can count toward compliance in limited circumstances under interpretive guidance.
Exceeding the cap blocks permit issuance, requires redesign before continuation, and can force removal of excess hardscape at the owner's expense with after-the-fact fees.
