, The geotechnical report for the Ambleside Meadows - 1st 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 offill compacted
to at least 95% of ASTM 1?698 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 least 24" above the expansive bearing soils, frrmlv
comoacted to reduce'the infiltration of water at the surface. The ~acy of fIll soil
. material around the building must be verified to the satisfaction of'the design
professional. ,
