The geotechnical report for the Ambleside Meadows - 1st Addition Subdivision
recommends inuriediate 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 f~...m collecting in or around the foundation areas
during and after the constrU~tion 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, finnlv
~omoacted to reduce the inflltration of water at the surface. The adequacy of fill soil
material around the building must be verified to the satisfaction of the design
professional.

2. The moisture content of the excavation was adequately maintained during the site
preparation process and was adequately covered to stabilized moisture content
prior to any significant change in moisture content of the sub-grade.
3. The site is adequately graded and drained to prevent the collection of water in the
excavated area during construction.
