East Honolulu hillside lots in Mariner's Ridge, Kamilo Iki, and Kuliouou Valley require grading permits under ROH Chapter 18A when land disturbance exceeds permit thresholds.
Chapter 18A is the primary chapter for grading, soil erosion, and sediment control in the city. Article 2 covers permits, bonds, and inspections. Sec. 18A-2.2 governs grading permit applications, and Sec. 18A-2.4A addresses penalties for grading without a permit. Article 3 covers grading, grubbing, and stockpiling. East Honolulu's steep terrain means many residential improvements like retaining walls, driveway expansions, and pool excavations trigger grading permits. Drainage provisions within permits ensure runoff does not cause downstream flooding or erosion toward Maunalua Bay.
Grading without a permit, violating permit conditions, or failing to bond the work can result in penalties under Sec. 18A-2.4A and restoration orders.
