Kaneohe's rolling terrain makes ROH Sec. 21-4.40 retaining wall rules especially relevant. Fill-retention walls in required yards cannot exceed 6 feet, and terraced walls are combined for height calculation.
ROH 21-4.40 governs retaining wall construction across Kaneohe. Walls containing fill within required yard setbacks are capped at 6 feet total. When walls are terraced up a slope, their heights are combined if separations are minimal, which matters on Kaneohe's frequent hillside lots in Haiku, Temple Valley, and the Ko'olau foothills. Walls over 30 inches require a building permit and usually stamped structural engineering. Proper drainage, including weep holes and French drains, is critical given Kaneohe's rainfall. Failures can cause severe downhill damage and owner liability. Geotechnical evaluation may be required for tall walls.
Unpermitted or over-height retaining walls may require reconstruction, after-the-fact fees, and create liability for downhill damage during rain events.
