In Urban Honolulu's redevelopment zones from Kakaako to Ala Moana, ROH Chapter 43 Article 11 and Chapter 14 water quality rules require strict MS4 compliance, with illicit discharge prohibitions enforced at construction and operation stages.
Urban Honolulu's coastline drains directly to the Ala Wai Canal, Kewalo Basin, and Honolulu Harbor, all receiving waters with elevated regulatory sensitivity under the MS4 program. ROH Sec. 43-11.22 prohibits discharge of effluent other than stormwater into the city separate storm sewer, and Sec. 43-11.12 requires approvals for storm sewer connections. For tower construction in Kakaako (HCDA jurisdiction) and Ala Moana (LUO), stormwater management plans must address both construction-phase BMPs and post-construction treatment such as bioretention and cisterns.
Illicit discharges near the Ala Wai or Kewalo drainage can result in DFM enforcement, state NPDES-backed administrative penalties up to $10,000 per day, and required remediation of affected stormwater systems.
