In accordance with your request, this report has been prepared to present the.
results of the in-place density tests performed at the subject site. These
tests were performed by Southern California Soil and Testing, Inc. between

Field density tests were performed by our firm in accordance with ASTM'01556-
82 and ASTM 62922-81. The tests were performed at the request of and-at the
locations chosen by Mr. Jay Hall, Püplic Works inspector for the City, of
