The undersigned design professional (or authorized einployee) attests tha@she
observed required moisture stability procedures on this site, and that such procedures
were accomplished before any changes occurred in the moisture content of the sub-
grade under mid around the building (where expansive soils were encountered). The
undersigned further attests that the sub-grade, as prepared, is adequate to support the
building proposed for this site.

The geotechnical report for the Ambleside Meadows -:- 1 sl 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 of fill compacted
to at least 95% of ASTMD698 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, firmly
compacted 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.
