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.

Volunteer Opportunity with Dozer Days

The ASCE geotechnical group would like to introduce you to a wonderful family and child friendly event – Dozer Days.

Check out their website

The event is a family event where children are given the opportunity to drive construction equipment. There are also booths where organizations can set up and encourage the parents and children to obtain education and training that would allow them to enter the civil construction/engineering field.

Washington State Fair & Events Center (Puyallup Fairgrounds), Puyallup, WA
Saturday and Sunday June 4th and 5th.

If you would like to volunteer for this event please contact Mark Rohrbach at

Volunteers Needed for New Committee

In response to changes to the building code (IBC 2012 vs. IBC 2008 and ASCE 7-10 vs. ASCE 7-05), recent research regarding the effectiveness of “discrete reinforcement based” ground improvement designs and widely diverging ground improvement designs and design methods, the Seattle Chapter of the Geo-Institute is forming a committee to assess local standards of practice regarding design and construction of discrete ground improvement elements (e.g. compacted aggregate piers, controlled modulus columns, rigid elements, etc.) with the goal of deciding if some form of a ground improvement guidance document is necessary.  The City of Seattle’s DPD has indicated that a guidance document of some form would be helpful in their review of ground improvement design submittals.

Ideally the proposed committee will consist of consulting geotechnical engineers, ground improvement design engineers, ground improvement contractors, and public officials.  If you are interested in participating in this committee, or would like to be kept appraised of committee developments please contact any member of the Board. This invitation to participate in the planned committee will remain open until the committee is appropriately staffed.

Please contact and if you are interested.
