See Detail 26 on Sheet D2 and structural calculations. It appears that a retaining wall with a <br /> height of up to 10 feet is specified. Retaining walls supporting more than 6 feet of backfill <br /> height measured to the bottom of the footing should include an additional seismic lateral earth <br /> pressure IBC 1807.2,2. Note that it appears that a 10-foot-tall retaining wall may not be <br /> necessary for the project. The elevations on Sheet 2 specify a 3'-6"tall concrete wall and the <br /> site appears to not require a significant amount of grading to result a 10-foot retaining wall. <br /> The detail may be modified to eliminate the options for retaining walls taller than 6 feet <br /> (measured from the bottom of footing to grade)and no additional calculations would be <br /> required, or calculations may be updated to include the additional seismic lateral earth pressure <br /> for walls taller than 6 feet. <br /> The retaining wall and calculations have been removed. <br /> �AR� <br /> Ol WASFII <br /> 11/18/2021 _ <br /> Report#2104 '` <br /> John HodgI <br /> NoN <br /> . f Hodge Engineering,Inc. <br /> John E.Hodge P.E. <br /> 3733 Rosedale St NW,Suite 200,Gig Harbor,WA 98335 <br /> 7 ' (2 i3) 857-7055 <br />
