Dear Mr. and Mrs. Jewkes:
This report summarizes the results of our geotechnical observation and testing services
associated with the recent grading for the future residence and associated site improvements
within Lot 66 of Tract No. 7223 located in the Big Canyon community, City of Newport Beach.
The demolition and backfrll of the former swimming pool and spa is described in our reference
(3) report which was previously submitted to the City of Newport Beach for their review and
approval.
Geotechnical Observation and Testing
GMU performed observation and testing related to the remedial grading and subsequent fill
placement as follows:
• All significant organic materials, debris, or other decomposable materials were
removed.
The basement pad subgrade was excavated into in -place competent terrace deposit
materials considered suitable for the support of the planned improvements.
The portions of the site remaining at grade or to receive new fill were over -excavated
to a minimum depth of 24 inches exposing in -place competent compacted fill
materials considered suitable for the support of the planned improvements.
o Prior to placing the fill materials, the bottom areas were scarified to a depth of at
least 6 inches, moisture conditioned as necessary to over optimum moisture
content, and compacted in place to a minimum relative compaction of 90%.
• The fill materials consisted of on -site soil materials which were placed in thin lifts,
moisture conditioned as necessary to over optimum moisture content, and compacted
to a minimum relative compaction of 90%.
