Dear Mr. Halvorson:
DAVE EARL.ING
MAYOR
The Earth Subsidence Landslide Hazard provisions of the Edmonds Community Development
Code Chapter 19.10 limit land development to the drier season of the year, specifically between
May I" and September 30th. All groundwork, including grading and drainage installation must
be completed by September 30`t' 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 30"'. 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 15`, 2015.
Regardless of whether work commences or is stayed until May lsr, 2015, the geotechnical
engineer of record does need to make winterization recommendations in an addendum or 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 stilt
required to be submitted to the City inspector upon request.
In the case that the groundwork is stayed, it is possible to recommence the groundwork prior to
May lir, 2015 provided an evaluation by the geotechnical engineer confirms the site conditions
are stable and work may start without creating erosion or stability problems. These would, of
course, need to be submitted for approval prior to recommencing work. If you have any
questions please feel free to contact me at 425-771-0220 during City business hours.
Sincerely,
Leif orbauk, CBO
