Permit Application Review
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.
