The geotechnical report for the Ambleside Meadows - 1 sl Addition Subdivision
reco~nds 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 0698 for foundation preparation. The report also rec....uuuends
that measures be taken to prevent water i~VAU collecting in or around the foundation areas
during and after the construction process, aDd 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, fim1lv
eomJ23Cted 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.

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.
4. The accompanying repon titled "Site Investigation Questionnaire for Consulting
Design Professionals>J containing field observations and instructions made on
