Commission on Water Resource Management

The Commission is in the process of transitioning to an electronic notification process for Stream Channel Alteration Permits (SCAP) and Stream Diversion Works Permits (SDWP).  Full paper copies of permit applications will no longer be mailed to government agencies for review.  When a permit application is ready for review, a PDF file will be posted below under the respective County heading.  Each permit application will be listed by ID number and title, followed by the applicant, project summary, file size and deadline for comments. Click on the permit application ID number and title to download and/or view the application.

NOTE: Due to large file sizes, it is suggested that you save the PDF file to your computer, then open the file.  Attempting to open the PDF file within your browser window, may result in slow performance or cause the browser window to freeze.

Island of Kaua‘i

  Applicant: Kaua‘i Island Utility Cooperative
  Landowner: State of Hawai‘i
  Project Summary: The proposed work includes the following listed by stream name
  1. Waiakōali. One concrete headwall with a control gate.
  2. Kawaikōī. One gravel cofferdam with a gated pipe and trash rack.
  3. Kōkeʻe. One 36-inch bulkhead with gate and one 85-foot long 24-in HDPE pipe flume.

  The proposed changes will result in less water diverted into the ditch and more water retained in the streams. It is intended to address the requirements for Phase One interim instream flow standards outlined in the mediation agreement for the Waimea Watershed Area approved on April 18, 2017 by the Commission on Water Resource Management.
