GEOLOGIC REVIEW 'SHEET
Item I
Regarding Item B of 12--6--76 review relative to Section AA -AA.'
and BB -BB': it is understood that an addendum (verbal with
geologist 12-15--76) is to be submitted regarding detailed recom-
mendations fo.r appropriate shear key type fills with restricted
use areas downslope and 5 foot blanket over cut 'Pads as per
12-14-76 report above Diamond Bar landslide, Lot 79-82 area."
Two smear keys have been designed and are proposed for Lots
79-82 area. At the rear of Lots 79 and 80, a 15 foot aide by
30 feet deep shear key with 1:1 side slopes is proposed. At
the rear of Lot 82, a 15 foot wide by 32 feet deep shear key
with 1:1 side slopes is proposed. For locations and other de-
tails refer to cross section AA -AA' and HH-HH' and sheet 5
of 6 of Geologic Map. These shear keys have been designed to
be excavated deeper than the critical plane as projected from
the base of the Diamond Bar landslide. Additionally, Lots 79-82
should be blanketed with a relatively impermeable material as
discussed in the previous reports to a depth of 5 feet below
finished grade.
The proposed key ."or the fill slope below Lots 76-79 and as

depicted on cross section BB -BB', should be deepened to 8 feet,
rather than 3 feet as previously indicated, below the toe of
the fill slope. This modification is shown on the enclosed
cross section BB -BB', and as well as on the Geologic Map, sheet
5 of 6. This deepening of the key was reco=ended in order
to have the fill keyed in below the critical plane projected
from the base of the Diamond Bar landslide.
A restricted use area is shown on the Geologic Map below Lots
79, 80 and 81 from the edge of the daylight cut, downslope
to the tract boundary.

Soil Engineering Section Requirements attached (12-24-76),
buttress calculations, and analysis for stability for sliver

All modifications have been transmitted to the design engineer,
VTN and are now on the plans. The plans have been signed and
submitted.
Sheet 7 in the 12--13-76 report is not a part of the proposed
grading plan to be approved.
SOIL ENGINEERING REVIEW SHEET
Item 1
In analyzing for potential failure beneath the buttress fills,
the consultant is relying only on the Mohr's circle criteria
developed by R.T. Frankian However, past observations indicate
that the principles of passive resistance and block slide with
some rotation are valid considerations for analyses. Therefore,
the consultant must consider the above in his analyses. Utiliz-
ing the above principles we find that the buttress in Section
A -A' is satisfactory."
As suggested by Mr. Sudduth, the "principle of passive
resistance and block slide with some rotation" were applied
to sections B-B', D,-D', H-H', K-X' and N-N'. However, it should'
be noted that if Frankian's solution is applied, rupture below
the passive block is curvilinear and ground surface break will
occur far beyond the toe. Accordingly, passive resistance
to failure would be greater than that computed. using Mr. Sudd uth's

failure mechanism.
December 29, 1976
W. O. 605
In using Nir. Sudduth's failure mechanism to section N-N', a
20-fooL deep key would be required to attain a factor of safety
of 1.0 under psuedo--static conditions. In view of this result,
we suggest that Mr. Sudduth consider the "down -drag" forces
mobilized along the vertical plane between the active and the
passive block. The downward -movement of the active block will
tend to mobilize the shear resistance along the vertical plane.
This shear resistance, Sd can be defined as the quantity
cL + N tan 0), using the peak strength parameters of the but-
tress fill and the unbalanced normal force, N, transmitted by
the active block. This shear resistance is then resolved as
an additional normal force on the 300 failure plane below the
passive block. This induced normal force will increase the
frictional resistance along the 300 failure planes. Apply-
ing the foregoing principles to section M-N', and adopting a
10-foot deep key, a safety factof of 1.34 is obtained.
In view of the foregoing results, we herein recommend a 10--foot
deep key for section PI-N'.

Item 2
December 29, 1976
W. O. 605
Section AA. -AA' must be analyzed using bedding plane shear values
in accordance with our discussions."
This item is answered in our response to Item 1 of the geologic
review sheet. Calculations are enclosed.
Item 3
Secticn BB -BB' buttress fill rests on unsupported natural mate-
rials that may be unstable."
Similarly, this item is covered in our reply to Item 1 of the
geologic review sheet. Calculations are enclosed.
Item 4
Section CC -CC' has a theoretical cut off depth that is too
deep when compared with the shear values used in the report. A
safety factor must be applied to the driving force only. Height
ratios for determining safety factors are not acceptable."
We acknowledge your definition of "factor of safety" which is
Itek
different from our height ratio criteria. In 44 of providing
a buttress fill at the toe of the slope, we recommend benching
into the underlying bedrock materials along the critical bedding

plane projected from the toe of the slope and making a 10-degree
angle ,Ath the horizontal.. In order to prevent failure aloncr
the of the benches, we recommend a 30-foot wide bench below
the thickest proportion of the proposed fill slope. This is
shown on section CC -CC'. This bench will serve to induce failure
through the fill and across the bedding, both of which offer
such higher shear resistance.
Item 5
Comments on Section B-B' and N-N' as analyzed."
a. "The theoretical cutoff depth appears to be too deep when
compared with the shear values used in the report. A safety
factor must be applied to the driving force."
b.. " The cross --section does not show*enough of the slope to
be analyzed."
C. "Utilizing R.T. Frankian's method, it has been found that
the steepest failure plane angle within the buttress fill
was about 5 degrees."
Section B-B' and N-N' were reanalyzed based on the._,lengthened..
cross -sections and applying a 1.5 factor of safety to the driv-
ing forces in determining the theoretical cut -off -depth. All
these are reflected in the attached cross-section and calculations.

W. O. 605
Submit a recommended layout of the proposed subdrainage system
along with a cross-section showing the locations of the pipe
perforations, pipe perforation size, pipe size, filter and drain
materials locations in relation to the pipe and all necessary
dimensions."
The recommended layout of the proposed subdrainage system along
the canyon areas are shown on the geologic map. The recommended
filter material around the perforated pipe and size of pipe per-
forations are based on the following criteria which will prevent
migration ,of fines through the filter, insure sufficient per-
meability, and prevent migration of filter material ,through the
pipe performations.
To prevent migration of fines or piping:
D15 (of filter)
D85 (of native soil)
5
To ensure sufficient permeability:
D15 (filter)
D15 (native soil)

S. E. &Jadaij & Assoc ales. Inc.

To prevent movement of filter material through pipe holes
or slots:
D85 (of filter) 1.2
Slot Width
or D85 (of filter.)
1.0
Hole diameter
The pipe perforations or slots should be restricted to approxi-
mately the bottom 40 percent of the pipe circumference. The
upper end of the pipe should be plugged.
The foregoing criteria are reflected in the attached grainsize
distribution_ curves showing the gradation of the native soils
or fill materials and the filter.
r a- --m "7
Submit grain size gradations for the filter and drain materials
and demonstrate that they will not be clogged by migrating fines."
This is shown in the attached grainsize distribution curves.
The recommended gradation of filter material will prevent migra-
tion of fines in accordance with the foregoing criteria.
