Grading Season Restrictions Began November 1

The rainy season is here. This means that grading activities are restricted between November 1, 2014 and March 31, 2015. If your project includes Geotechnical Special Inspections AND if your project is in an environmentally critical area or involves a large quantity of earth-moving, check the Geotechnical Special Inspection assignment letter DPD sent you shortly after your permit was issued.

For smaller projects in environmentally critical areas, there may be a note in the assignment letter allowing you to follow the additional measures for wet weather work shown on the approved plan set in lieu of a formal grading season extension application.

For information on how to apply for a Grading Season Extension, see Director’s Rule 17-2011, available on the DPD website. This year, you must submit an application online through your DPD Project Portal at http://web6.seattle.gov/DPD/eplan/. We will not accept paper applications. We may take up to two weeks to review your application. Please note that your permit must be issued before we can process a grading season extension application. Contact the on-call geotechnical engineer at (206) 684-8950 if you have questions about submittal requirements or whether you need an extension.
