Kaneohe residential lots must meet ROH Sec. 21-3.70-1 impervious-surface caps. Dwellings permitted after May 1, 2019 are limited to 75 percent impervious coverage to manage runoff into Kaneohe Bay.
ROH 21-3.70-1 caps impervious surfaces at 75 percent for Kaneohe dwellings permitted on or after May 1, 2019. The rule addresses stormwater runoff that drains toward Kaneohe Stream, He'eia wetlands, and the bay. Impervious surfaces include houses, garages, concrete driveways, walkways, and pool decks. Pervious alternatives like open pavers, gravel, and planting beds count as pervious. Older homes may be grandfathered until substantial remodel triggers re-evaluation. The cap interacts with setback and floor-area limits so tight urban lots fill up quickly. Careful site planning preserves usable outdoor space while staying compliant.
Exceeding the impervious cap halts permit approvals, and retroactive discovery may require removing pavement, decks, or structures to restore compliance.
