INTRODUCTION
This report presents the results of our observation and testing
performed during construction and grading for the residential pad
during rough and fine grading of the subject lot.
The pad was constructed on the north side of Avenida Del Reposo,
along the top of the ridge and steep north-facing slope. The
results of our Field Density Tests obtained during grading are
tabulated in Table I, Results of Compaction Tests. The approximate
locations of the tests are shown on the Plot Plan, Plate 1. The 20-
scale Grading Plan was prepared by TEC Inc., Temecula, and dated
November 11, 1993.
Proiect Description
The proposed development consists of constructing a ,building pad
along the ridge top paralleling Avenida Del Reposo.
Grading consisted of 7-8 foot cuts at 2:1 (horizontal to vertical)
along the front or south side of the lot, and 17 foot high fills
along the north at finished inclinations of 2:1 The fill required
a keyway constructed at the location shown on Plate 1. In addition,
the transition lot required overexcavation to a minimum of 3 feet
from finished grade.

Gradinq Contractor
Grading and backfill operations were conducted
Grading, Murrieta, under the superbvision of Mr.
general engineering contractor.
by Blackmore
Ken Blackmore,
Purpose of Gradinq
The purpose of the grading was to prepare the site for the proposed
construction of the one-story single family residence and driveway
access.
GRADING PROCEDURES
Gradinq Procedures
The area to receive fill was steeper than 5:1, so a fifteen foot
wide key way was excavated at the toe of the fill slope. The keyway
was founded in firm Pauba bedrock, then overexcavated 1 1/2 - 2
feet, moisture conditioned and level backfills placed to pad
grade. Cut material from the south was placed as compacted fill.
The fill materials were brought to near optimum moisture, and
compacted with a D8 Caterpillar bulldozer.
Water was provided with a 1.5 inch fire hose from a nearby fire
hydrant.
TESTING
Field Densitv Testinq
Field density testing was performed in accordance with ASTM D 1556
(Sand-Cone Method). The elevations and the results of the field
densi ty tests are presented in Table I of this report. The
approximate location of the tests are shown on the Plot Plan, Plate
1.
Maximum Densitv Determinations
Maximum density/optimum moisture determinations were made from
representative samples of on-site soils used in the fill
operations. The tests were performed in accordance with ASTM D
1557 which consist of compacting 5 equal layers of soil in a 1/30
cubic foot volume mold with 25 blows of a 10 pound hammer falling
18 inches. The results of the Maximum density/optimum
determination are presented herein as Table II, Laboratory Test
Results.

SUMMARY
Our description of grading and backfill operations, as well as
observations and testing services, were limited to those grading
operations performed between February 1 and February 3, 1994. The
conclusions and recommendations contained herein have been based
upon our observation and testing as noted. It is our opinion, that
the work preformed in the areas denoted has generally been
accomplished in accordance with U.B.C. Chapter 70 specifications,
