ROH Sec. 21-3.70-1 limits impervious coverage on Kapolei residential lots, including a 75 percent impervious cap for dwellings permitted after May 1, 2019.
Kapolei's sunny, free-draining soils make impervious coverage a significant stormwater management issue. ROH 21-3.70-1 caps total impervious surface, including roofs, paving, and pool decks, at 75 percent for dwellings permitted after May 1, 2019. Developers of master-planned blocks typically meet the cap through design, but owners adding pools, ADUs, or expanded driveways often run into the limit. Some pervious paver materials may reduce the calculated impervious area. Commercial lots follow separate standards with greater coverage but stricter stormwater BMP requirements.
Plan check denials, required removal of over-paved area, and fines for overbuilt lots.
