Waipahu construction projects need erosion and sediment control plans under ROH Sec. 18A-1.6 before any building, grading, stockpiling, or trenching permits may issue.
Chapter 18A requires approved erosion and sediment control plans for land disturbing activities. Waipahu's dense development and flat lowland terrain still produce substantial construction sediment, and direct drainage pathways to Pearl Harbor make control essential. Plans must include silt fencing, stabilized construction entrances, inlet protection, and revegetation measures. Inspectors monitor installation and maintenance, and sediment discharges from a Waipahu site can quickly reach the estuary through plantation-era ditches and modern storm drains. Failure to maintain controls can stop work.
Beginning land disturbance without an approved plan, or failing to maintain controls, can lead to stop-work orders and fines.
