Ground Improvement Committee Document – Comment Period

The September 16, 2016 deadline for comments is approaching quickly:

After nearly 6 months of effort, the Ground Improvement Committee is pleased to announce a commentary guidance document has been prepared.

These commentary guidelines are the result of a request to evaluate common approaches for ground improvement design as it relates to the use of ground improvement to mitigate against liquefaction and/or improve Site Class.  The purpose of the document is to provide commentary guidelines that address concerns regarding the disparity of approaches for ground improvement design and design recommendations submitted to the City of Seattle Department of Construction and Inspections (SDCI) and other code enforcement organizations in support of construction permit applications.

This announcement marks the beginning of a comment period that ends September 16,, 2016.  The ground improvement committee and the ASCE board respectfully request you review the document and send any comments you may have to Mark Rohrbach at  To the extent possible, it would be greatly appreciated that companies pool their comments into a single consistent document.

City of Seattle – Grading Season Deadline Approaching

The rainy season is rapidly approaching, which means it’s time to think about whether you will be doing any grading between November 1, 2016 and March 31, 2017. 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 we sent you shortly after your permit was issued.
If you see an item called “Monitor Grading Season Restriction” on the assignment letter, this means that grading between November 1, 2016 and March 31, 2017 is prohibited unless you apply for and receive a Grading Season Extension. 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 26-2015 (effective early Oct. 2016). This year, you must submit an application online through your SDCI Project Portal at 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.
