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 ASTMD698 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 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 fInish grade of landscape soil ,
. , adjacent to the foundation should be at leasf24" above the expansive bearing soils, fmnlv,
comoacted 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. .
