Subject: Geotechnical Clarification — Final Inspections
CITY 0I- �p�o a s 0 r
This engineering letter clarifies final geotechnical inspections (see July 26,
2007 report) for the recently completed Gerdes new residence at 7418 169th PL
SW (plan check # 2006 -- 0659)
As discussed in the July 96, 2007 final report, all special geotechnical
inspection items have been properly completed except for the permanent
erosion control measures.
It is understood that property owner (Dr. Art Gerdes) proposes to install
permanent landscaping and erosion control measures in the coming months.
This engineer has no objection to delaying permanent erosion control measures
as long as they are completed by October 31, 2007 (stark of rainy season).
The Gerdes property is currently stable. The perimeter siltation fencing is
still in place and provides excellent erosion control. However, it is essential that
the permanent erosion control measures and landscaping be properly completed
.by October 31, 2007.
Discussions with City of Edmonds (Janine Graf) clarified that Mr. Gerdes
should post a bond to verify with the City of Edmonds that the future landscaping
measures will actually be completed. It is understood that Mr. Gerdes and / or his
contractor will follow through with the appropriate bond paperwork.
SUMMARY:
•- The Gerdes site is currently geotechnically stable pending permanent
erosion control measures properly installed prior to October 31, 2007
SOILS * FOUNDATIONS • SITE DEVELOPMENT • INSPECTION • DRAINAGE • DESIGN & PERMIT LEGAL
