Litter destroys the natural beauty of Hawai‘i’s highways.

Mahalo for your participation!

The public comment period is now closed. The State of Hawaii Department of Transportation, Highways Division, Oahu District (DOT-HWYS) appreciates your patience while we incorporate the public’s input and finalize the Storm Water Management Program Plan. The final plan will be posted at www.stormwaterhawaii.com on April 27, 2015. Thank you again for your participation as DOT-HWYS strives to reduce the amount of storm water pollutants entering and ultimately discharging from our MS4 into the streams, rivers and ocean that we all enjoy.
