Dear Cynthia:
Soil & Environmental Engineers, Inc. (S&EE) has performed a geotechnical evaluation for the above -
referenced project. The report of this evaluation is dated March 18, 2017 and has been submitted to you
previously. At the request of Mr. Michael Sullivan, I have reviewed our file and the requirements for onsite
infiltration (C.2.2.1 item la, 2017 City of Renton Surface Water Design Manual). It is my opinion that
onsite infiltration is infeasible as the site soils consist of fill materials in the upper 10 to I 1 feet.
I trust that this communication will serve the current need. If there is any question, please call.
Very truly,
SOIL & ENVIRONMENTAL ENGINEERS, INC.
