Subject: Proposed Tuscany Ridge Apartments, Margarita Road, East of Moraga Road,
Temecula, California; Additional Geotechnical Investigation
References: (1) Preliminary Geotechnical Investigation, RM Environmental, Project No.
96-252.100, March 28, 1997
(2) Plot Plan, Rick Engineering Company, June 1997
Gentlemen:
As requested, we have completed an additional geotechnical investigation for the subject
project. The purpose of the investigation was to further define soil conditions identified in the
referenced Preliminary Geotechnical Investigation and to provide additional grading and paving
recommendations.
PROPOSED DEVELOPMENT
The proposed 13.8 acre Tuscany Ridge apartment development will include the construction of
16 two-story multi-family structures, a recreation building, garages, carports, and a swimming
pool. Associated driveways, parking, and landscaping are also proposed. It is understood that
the proposed apartment building foundation systems will be post-tension slabs. An Index Map
showing the general vicinity of the site is presented on the following page. The general site
configuration is shown on the attached reduced copy of the plot plan, Enclosure 1.
PRELIMINARY GEOTECHNICAL INVESTIGATION
The referenced Preliminary Geotechnical Investigation identified loose alluvial and/or colluvial
soils generally blanketing the flanks of the central, east/west trending ridge at the site. The

loose soils ranged from 1 to 4 feet along the south side of the ridge, and from 3 to 14 feet along
the north side of the ridge. The referenced report recommended that the alluvium and/or
colluvial soils be removed to expose the underlying sedimentary bedrock (Pauba Formation)
within building and fill areas.
SUBSURFACE INVESTIGATION
On August 12, 1997, additional subsurface exploration and soil testing was conducted at the
subject site by this firm. A total of 13 exploratory pits were excavated utilizing a tractor
mounted backhoe. The purpose of the exploration was to more closely delineate the areas of
potentially compressible soils located along the flanks of the central ridge, and provide
additional soil test data to support our findings. The approximate locations of the test pits are
shown on Enclosure 1. The soils encountered in the test pits were examined and visually
classified. A summary of the soil classifications appears in the test pit logs, Enclosure 2. The
test pit logs show subsurface conditions at the dates and locations indicated, and may not be
representative of other locations and times. The stratification lines presented on the test pit
logs represent the approximate boundaries between soil types and the transitions may be
gradual. Relatively undisturbed samples of the soil were obtained at selected levels within the
test pits. The undisturbed samples, together with bulk samples of typical soil types, were
returned to our laboratory for testing and evaluation. Laboratory testing included moisture-
density tests on all undisturbed samples. Maximum dry density-optimum moisture content
relationships were established so the relative compaction of the in-place soils could be
computed. The moisture and density data are shown on the test pit logs, Enclosure 2. The
maximum density test data appear on Enclosure 3.
ANALYSIS
Through observations and tests conducted in the exploratory pits, we were able to identify
potentially compressible soils along the southerly and northerly flanks of the central ridge. The

potentially compressible soils underlie the southern side of the central ridge to depths ranging
from 1 to 6 feet with an average depth of approximately 3 feet. Potentially compressible soils.
underlie the northern side of the central ridge, including a seasonal drainage, channel, to
depths ranging from 3 to 15 feet, with an average depth of approximately 9 feet. Interbeds of
sedimentary bedrock (Pauba Formation), consisting of silty sands, clayey sands and sand,
underlie the central ridge. The surface of the central ridge is blanketed with 1 to 2 feet of loose
topsoil. The limits of the potentially compressible soils are delineated on the attached reduced
copy of the plot plan, and coincide approximately with the proposed cut/fill line.
CONCLUSIONS AND RECOMMENDATIONS
It is our judgment that the conclusions and recommendations presented in the referenced
Preliminary Geotechnical Investigation remain applicable with the exception of subexcavation
and pavement design recommendations as presented below.
Proposed grading will cut down the central ridge and, in turn, the material will be placed to the
north and south as compacted fill over the areas presently underlain by potentially compressible
soils. The soils identified as being potentially compressible will likely compress upon loading
with the proposed fill; therefore, we recommend the compressible soils be subexcavated and
recompacted.
Based on our exploratory pit data, we conclude that the upper 1 to 6 feet of existing soil (3 feet
average) should be subexcavated beneath the proposed fill areas located to the south and west-
of the central ridge. In addition, the existing surficial soils located beneath the proposed fill
areas to the north of the central ridge, including the seasonal drainage course, should be
subexcavated to a depth of 3 to 15 feet (9 feet average). Due to the relative steepness of the
central ridge, the proposed fill depths will increase rapidly with distance from the cut/fill line.
This condition will create a potential for differential settlement along foundations that span from
the bedrock exposed in the cut to the fill. To minimize the potential for differential settlement,

we recommend that the areas underlying the cut portion of transition building pads be
subexcavated to a depth of 3 feet below finish grade. The soils exposed at the bottom of the
subexcavations should be scarified to a depth of 8 inches, moistened to a near optimum
moisture content and compacted to a relative compaction of at least 90 percent. The
subexcavated soils should then be replaced in lifts, moistened to an approximate optimum
moisture content, and compacted to a relative compaction of at least 90 percent (ASTM D
1557).
A representative sample of the surficial soils was returned to our laboratory for gradation, sand
equivalent and "R" value testing. The subgrade soil test results are tabulated on Enclosure 4.
Based on the results of these tests ("R" value of 12), it is. our opinion that a reasonably durable
pavement section for on-site driveways and parking areas would be provided by 3.0 inches of
asphalt concrete over 7.0 inches of aggregate base. .
We appreciate this opportunity to be of service. Should there be questions, please contact this
office.
