St. Lucie County, Florida

Attn: Mr. Andrew Culpepper
Based on the results of our earthwork observations and density testing during the mass grading, and our
field exploration program, we believe that the shallow subsoils at the referenced location are suitable to
support shallow foundations and a slab -on -grade that are designed for a net soil contact pressure of 2500
pounds per square foot (psf). Based on the results of the in -place density tests (see the attached Soil
Density Test Report on Sheet 2), the fill placed to bring the slab subgrade to final construction elevation
has been compacted to at least 95 percent of the ASTM D-1557 maximum dry density.

Notes: The original of this report was signed and sealed by the registered engineer in accordance with Rule 61G15,18.011, of the
Florida Administrative Code. This report is submitted as the confidential property of our client and authorization for publicatidrt of
statements, conclusion or extracts from or regarding this report is reserved pending our written approval. Building area soils exclude
those within the lot front, rear and side set backs.
Limitations: The representations made in this report are based on periodic observations and spot testing of completed, mass earthwork.
The attached test results reflect conditions at the time the tests were performed at the locations and depths indicated on the data sheets. It
should be recognized that soil conditions may differ locally from those shown by our observations and tests, or as a result of weather
andlor marl -caused disturbances subsequent to the testing. If differing conditions am -found during construction, DE&T should be
notified immediately to determine if a change in foundation recommendations is required. If DE&T is not retained to perform these
functions, DE&T will assume no responsibility for the impact of these conditions on the project.
DE&T warrants that the findings, recommendations, or professional advice contained herein have been made in accordance with
generally accepted professional geotechnical practices in the local area. No other warranties are implied or expressed.
This report has been prepared for the exclusive use of Centex Homes for the specific application to support shallow foundations and a
slah-on-evade for home construction within the Palm Breezes Club development in St. Lucie County.

Remarks:
The gmundwater levels reported on the boring logs "represent conditions at the time of drilling. The water level meal irementswere made immediately upon completion of the
drilling and the water table may not have been fully stabilized at the time. Water table levels on the site are expected to fluctuate throughout the year in response to rainfall,
irrigation, drainage and other such factors.
The borings are representative of subsurface conditions at the time they were drilled for their respective locations and vertical extents. The boring logs and soil classifications
are based on the driller's logs and visual -manual examination of selected soil samples in our laboratory. The delineation between soil types shown on the logs is considered to
be approximate. Variations in subsurface conditions may occur between borings.
