Urban Honolulu tower and infill projects in Kakaako, Ala Moana, and Waikiki must submit erosion and sediment control plans under ROH Sec. 18A-1.6, protecting tight streets and storm drains that discharge directly to sensitive coastal waters.
Sec. 18A-1.6 applies to any project in Urban Honolulu requiring a building, grading, stockpiling, or trenching permit. In dense neighborhoods like Kakaako's mixed-use block grid or Ala Moana's boulevard corridor, BMPs typically include perimeter fabric, inlet protection on every adjacent storm drain, track-out controls at site exits, and covered stockpiles given tradewind conditions. DPP often requires enhanced controls in Urban Honolulu because sediment reaches receiving waters through short, direct storm sewer runs. The plan must be approved before any ground disturbance.
Sediment reaching public streets or storm drains in Urban Honolulu can trigger stop-work orders, civil fines up to $1,000 per day under Chapter 18A, and separate MS4 enforcement under ROH Chapter 43 Article 11.
