The report also recommends that measures be taken to prevent water from collecting in or around the foundation areas during and after the construction process, and that positive site drainage be provided to reduce the infiltration of surface water into the expansive soils, The geOtechnical report further emphasizes that the fmish grade of landscape soil adjacent to the foundation should be at least 24" above the expansive bearing soils, finnlv comnacted to reduce the infiltration of water at the surface, . The adequacy of fill soil material around the building must be verified to the satisfaction of the design professional. 4 tl4/~~/~tltll 15:12 5416849358 K& A ENGINEERING PAGE 06 Community ~ervices DiV'~: ,,"'i1ding Safely CITY OF SPRINGFIELD> OREGON 22.5 Slh Street, Springfield, OR 97477 Ph, 726-3759 Job Address '$7 :~IJ.L-~ /;U2.
