Emergency Stream Channel Work. PC: DLNR
With severe storm conditions affecting parts of the state, the Commission on Water Resource Management (Commission) has received reports of unauthorized stream channel alterations occurring on various islands. Such unpermitted work can threaten public safety by worsening flooding and diverting flood waters onto neighboring properties.
The Commission reminds landowners and operators to follow emergency authorization procedures if they need to perform substantial stream channel work, or for any stream channel work using heavy machinery.

If work exceeds what is considered “the minimum necessary,” the Commission may require corrective actions or issue fines of up to $5,000 per violation as provided under Hawaii Revised Statutes § 174C-15.
At the same time, Commission staff emphasizes that routine vegetation clearing and regular stream channel maintenance – conducted in advance of storm events – are critical to preventing blockages and reducing flood risk.
