The geotechnical report for the Ambleside Meadows - I" Addition Subdivision
recommends immediate moisture stabi1ization 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 preplll'llt.ion. The report also recOlDI1lellds
that measures be taken to prevent water from collecting in or around the foundation areas
during and after the construction r"".....a. 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 fmish grade of landscape soil
adjacenl to the foundation should be at least 24" above the expansive bearing soils, tim!!l:
co~ted. to reduce the infiltration of water al the surface. The adequacy of fill soil
material around the building must be verified to the satisfaction of the design
professional.
