ROH Sec. 21-4.40 limits fill-containing retaining walls in Kapolei to six feet within required yards and combines terraced wall heights for compliance measurement.
Kapolei's graded subdivisions and commercial pads rely heavily on retaining walls. ROH 21-4.40 caps walls that contain fill inside a required yard at six feet and combines terraced wall heights so stacking cannot bypass the limit. Most Kapolei retaining walls require engineered designs and a building permit, particularly on sloped sites near Palailai. Drainage and setback detailing matter because runoff from the higher Kapolei benches can affect downhill neighbors. Designers should also confirm HOA design standards and any master-plan requirements for uniform wall finishes.
Orders to reduce or remove walls, fines, potential civil liability for drainage damage, and permit revocation.
