Storm water is everybody’s business!
Construction is a major industry in our islands. However, while great for the economy, construction can have potentially disastrous effects on the environment. Construction activities can increase the rate of erosion by as much 1,000 times the natural rate. Sediment, the most common pollutant from construction activities, has been proven to cause monetary damages up to $16 billion per year.
Fortunately, HDOT Highways has a comprehensive construction site runoff control program to prevent water pollution during construction activities on State highways. Visit the tabs below for helpful information for design consultants and construction contractors working on HDOT Highways projects or with HDOT Highways right-of-way.
Designers
The plan to keep our water clean starts with design. Designers should consider both construction BMPs and permanent post-construction BMPs to minimize the environmental impact of the project. For files to assist in the development of site-specific construction BMP plans, please see below.

Contractors
Contractors play a critical role in mitigating the pollutants generated from active construction sites.
If you currently work for HDOT, or are thinking about doing work in HDOT rights-of-way, here are FAQs to consider before starting work on construction projects.
Do I need any permits for my project?
If you answer “YES” to any of the following questions, you will need a permit in order to start work:
Am I working within HDOT right-of-way?
PERMIT NEEDED: State of Hawaii Department of Transportation
Permit to Perform Work Upon State Highways
Will my project discharge into an HDOT storm drain?
PERMIT NEEDED: State of Hawaii Department of Transportation
Application and Permit To Discharge to the State of Hawaii Highways Division Storm Drain System
Will my project connect to an HDOT storm drain?
PERMIT NEEDED: State of Hawaii Department of Transportation
Application and Permit For A Private Drain Connections To The State of Hawaii Highways Division Storm Drain System
All HDOT permits are available at the Oahu District Office at 727 Kakoi Street in Mapunapuna.
Does my project disturb an acre or more of land?
PERMIT NEEDED: National Pollutant Discharge Elimination System General Permit Coverage or Individual Permit Coverage
For more information about General Permit or Individual Permit coverage, please visit the State of Hawaii Department of Health website.
Do I need a Site-Specific Construction BMP Plan?
If you answer “YES” to any of the following questions, you need a Site-Specific Construction BMP Plan:
- Am I working on a project requesting a State of Hawaii Department of Transportation Application and Permit To Discharge to the State of Hawaii Highways Division Storm Drain System?
- Am I working on a project requesting a State of Hawaii Department of Transportation Application and Permit For A Private Drain Connections To The State of Hawaii Highways Division Storm Drain System?
- Am I working on a project requesting a State of Hawaii Department of Transportation Permit to Perform Work Upon State Highways?
