Construction projects can release sediment and debris onto streets and into storm drains

Contractors & Consultants

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 pre-construction rate. Sediment, the most common pollutant from construction activities, has caused monetary damages of up to $16B in a 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 doing work for HDOT Highways or with HDOT Highways right-of-way.

Designers

The plan to clean water starts in the design phase. Designers need to consider both construction BMPs as well as 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 an active construction site.

If you currently do work for HDOT or are thinking about doing work in HDOT right-of-way, you have come to the right place. Here are some questions you should ask before starting work on any construction project for HDOT or within HDOT rights-of-way.

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:

  1. Am I working within HDOT right-of-way?
    PERMIT NEEDED: State of Hawaii Department of Transportation
    Permit to Perform Work Upon State Highways
    This permit is available at the HDOT Oahu District Office at 727 Kakoi Street in Mapunapuna.
  2. 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
    This permit is available at the HDOT Oahu District Office at 727 Kakoi Street in Mapunapuna.
  3. 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
    This permit is available at the HDOT Oahu District Office at 727 Kakoi Street in Mapunapuna.
  4. 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:

  1. 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?
  2. 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?
  3. Am I working on a project requesting a State of Hawaii Department of Transportation Permit to Perform Work Upon State Highways?
