INTRODUCTION
This report presents comments from our review of geotechnical engineering analyses of the proposed VEK
on Aberdeen development located at 957 Aberdeen Avenue NE in Renton, Washington. Our services are
being provided to the City of Renton Department of Community and Economic Development in accordance
with our agreement dated September 21, 2020 and executed October 5, 2020.
The proposed development will include construction near Sensitive Slopes and a Protected Slope as
defined by City of Renton Municipal Code. The project also includes construction of a stormwater pipe
proposed within the protected slope that would discharge into stream and wetland buffers. The City has
requested a third-party review of the geotechnical report and grading plan to confirm that the analysis and
conclusions provided are appropriate before approving the development. We reviewed a geotechnical
report prepared for the project by The Riley Group, Inc. (RGI) dated September 2, 2020 addressing slope
stability. We also reviewed the preliminary civil plans prepared by Encompass Engineering and Surveying
dated May 8, 2020. We provided our comments on these documents in a letter dated October 15, 2020.
