REPORT, Eastgard Property, 270 Harrington Drive, Jefferson County,
Washington, dated January 17, 2007, by Aspect Consulting, LLC
Dear Mr. Eastgard:
We have received from Nathan Cleaver Septic Designs, Inc. a site plan dated 4/2/07, a listing
of the soil logs prepared for the design, and a descriptive operating procedure for the septic
system on the proposed residential project located at 270 Harrington Drive, in Quilcene,
Washington. We had previously completed the referenced geatechnical report for the site in
January 2007. At your request, we have evaluated the presented design as it pertains to the
geotechnical slope stability of the site.
The soil logs presented are consistent with our ob~rvations at the site. Based on the location
and size of the pressure beds and with the control discharge rate to the bed, Aspect Consulting
believes a properly installed and operated septic system (as detailed in the information
provided to us) will not cause significant impact to the slope stability at the site.
We are pleased to have this continued opportunity to work with you. If you have any
questions, please do not hesitate to call me at (206) 780-7720 .
Sincerely,
Aspect ~ons~it~
