Dear Mr. Woodruff:
As requested, The Riley Grc up, Inc. (RGI) has reviewed the referenced project plans. The site grading
will require up to six feet offiIIand less than five feet of cut. The building foundations will besupported
on spread footing foundations. It is consistent with the recommendation in the referenced
geotechnical report.
RGI noticed that a pervious concrete pavement is proposed as an alternative bid in the parking. The
native soil is dense glacial till that doesn't support infiltration. RGI recommends that pervious concrete
alternative bid be removed from the plan.
The design to be submitted to City of Renton have been reviewed and conform to the
recommendations of the analysis, report and follow-up design memos, and provided that the
conditions and recommendations are satisfied, the construction and development will not increase
the potential for sail movement ar settlement. The risk of damage to the proposed development and
from the development to adjacent properties from soil instability will be minimal.
RGI would be available to provide geotechnical inspection services during the construction of the
project per City of Renton's requirements.
We trust the information presented is sufficient for your current needs. If you have any questions
regarding this letter report a require additional information, please call us at (425) 415-0551.
Sincerely,
