The geotechnical report for the Ambleside Meadows _ 1 st Addition Subdivision recommends immediate moisture stabilization of exposed expansive sub-grades. and that expansive soils be over-excavated and replaced with at least -12 inches of fill compacted to at least 95% of ASTM D698 for foundation preparation. The report also recommends that measures be taken to prevent water from collecting in or around the foundation areas during and after the oonstIuction 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 finish grade of landsc.ape soil , adjacent to the foundation should be at least 24" above the expansive bearing soilst frnnly , COffiDacted 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
