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 D698 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 fuiish 8rade of landscape soil
adjacent to the foundation should be at least 24" above the expansive bearing soils, Jimilv
comDacted to reduce the infiltratio~ of water at tbe surface. The adequacy of fill soil \
material around the building must be verified to the satisfaction of the design
professional,
