Dear Mr. Saunders:
The Earth Subsidence Landslide Hazard provisions of the Edmonds Community Development Code Chapter
19.10 limits land development to the drier season of the year between May 1St and September 30th. All
groundwork, including grading and drainage installation must be completed by September 306h and the site be
winterized. If work of this nature is not complete and will overlap into the month of October or beyond, the
City requires a letter stamped and signed from your geotechnical engineer of record confirming that the site is
stable and work may continue past the ordinance deadline of September 30th. If such an extension is requested
it must include a detailed schedule of work that establishes a completion date. If the City does not receive
such notice from your Geotechnical Engineer of record it is understood that groundwork, as defined by
ordinance, shall be stayed until May 1St, 2016.
Regardless of whether work commences or is stayed until May 1 st, 2016, the geotechnical engineer of record
does need to make winterization recommendations in a field report and provide a copy to the City for approval.
Winterization measures typically include protection of exposed slopes with visqueen or hydro seeding,
installation and maintenance of temporary erosion control measures and other site stabilization work.
Weekly monitoring reports from the geotechnical engineer or designated erosion sedimentation control
supervisor are still required to be submitted to the City inspector upon request.
It is possible to start groundwork prior to May 1St, 2016 provided an evaluation by the geotechnical engineer
confirms the site conditions are stable and work may start without creating erosion or stability problems. This
would need to be submitted for approval prior to re -commencing work. If you have any questions please feel
free to contact me at 425-771-0220 extension 1380 during City business hours.
Sincerely,
