ROH Sec. 21-4.40 controls retaining walls in Ewa Gentry, limiting fill-containing walls inside required yards to six feet and combining terraced wall heights for measurement.
Retaining walls in Ewa Gentry often support graded pads and rear-yard slopes. ROH 21-4.40 caps walls that contain fill within required yards at six feet, and terraced walls are measured together rather than individually for height compliance. Walls supporting structural fill typically require engineered design and a building permit regardless of the yard-area exemption. Drainage design is critical on the Ewa Plain because of heavy rain runoff and expansive soils. Owners should coordinate with both DPP and their HOA architectural review committee before building or replacing a retaining wall.
Orders to lower, engineer, or remove non-compliant walls; fines; and liability for drainage damage to adjacent lots.
