Dear Mr.Thompson and Mr.Walgamuth:
As you authorized, we have completed excavation observations and compaction testing at the
above- referenced address. The purpose of the observations was to evaluate the suitability
of the natural soils to support the proposed house and engineered fill. The purpose of the
compaction testing was to evaluate whether the fill placed below footings was properly
compacted to support the proposed house.
`� Background
The previous house on this lot was removed. After the demolition process was completed and
footing excavations for a new house were started, petroleum contamination was encountered.
After a series of soil tests were completed, recommendations were made to remove the
contaminated soil from below the proposed new house. The excavation needed to remove the
contaminated soils only impacted a small part of the house footprint.
Excavation Observations
The excavation to remove the majority of contaminated soils was completed on September 14,
2009. (The verification of the removal of contaminated soil was not the responsibility of Braun
Intertec). The depth of the excavation to remove contaminated soils was extended to an
approximate elevation of 938.

1. Excavation Observations and Compaction Testing Report Prepared by Braun Intertec (1
copy)

3.
Per you request, enclosed is a copy of the compaction tests performed by Braun Intertec.
These results are for the work related to the impacted soil excavation and backfill at the 2933
Casco Point Road site under Land Alteration Permit#2009-00543 issued 8-31-2009. The
enclosed compaction results are only valid for the work performed in regards to the impacted
soil remediation, and are not related to any additional work that the home builder may perform.
The home builder should give the city copies of the compaction testing performed for their work
under separate cover.
Sincerely yours,
AMEC Geomatrix, Inc.

The proposed basement and lower garage floor was planned at elevation 956.67.
Visual observations of the excavation were completed from outside of the excavation. The soils
observed in the excavation bottom consisted of glacially deposited sandy lean clay. Based on
watching the backhoe complete its work, these soils were judged to be stiff to very stiff.
Compaction Testing
Imported sand was then used to backfill most of the excavation. The sand was placed in thin
lifts with each lift compacted by a remote-controlled vibratory compactor that was lifted into
the excavation after each lift was placed. The sand fill was placed in this fashion until it had
been placed and compacted to an approximate elevation of 952. On-site sandy lean clay fill
was then used to fill the remainder of the excavation up to about elevation 956.
Based on the depth of the excavation, we recommended that the fill placed in this excavation be
compacte�+to a minimum of 98 percent of the standard Proctor dry density (ASTM D 698). We
also recommended that most of the material used to fill the excavation consist of clean sand.
This was to limit the amount of potential settlement that deep fills (greater than 10 feet thick)
can experience.
To evaluate the density of the engineered fill that had been placed, density tests were taken in
the sand and clay fill. As you review the compaction test results, you will note that some of the
tests taken in ihe clay fill initially failed to meet minimum density requirements. These areas
were re-compacted and then retested. The tests, or retests, taken met or exceeded 98 percent
of the standard Proctor dry density. The compaction and Proctor test results are attached to
this report for your review.
Conclusions
Based on the results of our visual observations, it is our opinion that the natural soils observed
in the bottom and sidewalls of this excavation are suitable for the proposed house. However,
we did not observe the soils in the remainder of the house excavation.
Based on the results of the compaction tests, it appears that the engineered fill placed below
footings and basement floor slabs has been properly compacted and suitable for foundation
and floor slab support. Even though mostly sand fill was used to fill this excavation, the fill
soils could experience some settlement,estimated to be �to 1/2 inch. As the house �oads are
incrementally applied, the sand fill will adjust almost immediately. Therefore, we recommend
that the finish work be delayed until the framing and roofing has been substantially complete.
