Re: Bulkhead Wall Stability Addendum
Dear Mr. Loos:
DCI Engineers completed a stability review of the existing bulkhead wall at the proposed site for the Cedar River
Apartments located at 1915 SE Maple Valley Highway in Renton, Washington. Based on information provided by
Terracon Consultants in their report “Bulkhead Wall Stability Addendum” dated June 10, 2019, and per the
attached calculations, we have found the bulkhead wall to be stable with a minimum factor of safety of 1.3.
Through findings reported in the geotechnical addendum and limited visual observation we found no evidence of
deterioration or movement of the bulkhead wall, nor have we found any evidence to suggest impending failure
under normal loading conditions. The new development will not increase loading to the existing wall and
therefore additional steps to decrease pressures behind the wall or structurally reinforce the wall are not
required.
Sincerely,
DCI Engineers
