The report also recv........uds 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, .tirmlv 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 . . . 64/25/2661 15:12 5416849358 <;:ommunilY Services Dililding Safety Job Address ~ 3':tIt ~ .4L-CL'"J..u ~.
