Dear Mr. Abbott,
The above referenced projects are located in an Earth Subsidence and Landslide Hazard Area subject to the
provisions of the Edmonds Community Development Code (ECDC) Chapter 19.10, which limits land development
to the drier season of the year, specifically between May 1st and September 30". All groundwork, including
grading/excavation, drainage system installation, and foundation construction in areas subject to those provisions
would have to be completed by September 30, 2017 and the site be winterized. For work of this nature to continue
past the ordinance deadline of September 30, 2017, the City requires a letter, stamped and signed from your
geotechnical engineer of record to be submitted for review and approval, confirming that the sites are stable and
work may continue without creating erosion or stability problems. 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
1, 2018.
Groundwork performed after September 30, 2017 must follow the specific guidelines detailed in the letter from the
geotechnical engineer, including, but not limited to, the duration of the work, the type of equipment to use, any
additional temporary erosion and sediment control provisions that are required, and the applicability of special
inspections or other similar measures to verify conformance with the specified guidelines. Weekly monitoring
reports from the geotechnical engineer or designated erosion sedimentation control supervisor are required to be
submitted to the City inspector upon request.
In the case that the groundwork is stayed, it is possible to commence the groundwork prior to May 1, 2018 provided
an evaluation by the geotechnical engineer confirms that the site conditions are stable and work may start without
creating erosion or stability problems. This would, of course, need to be submitted for approval prior to
commencing work.
If you have any questions, please feel free to contact me at 425-771-0220 during City business hours.
