Re: Counrty Manor Retaining Wall to be located at 2742 Abejorro Street, Carlsbad, California.
Subject: Compaction Report & Special Inspection
INTRODUCTION
In accordance with your request and authorization we have provided limited earthwork observation and
compaction testing services during the construction of the country manor retaining wall at the above
referenced site. The results of our quality control and compaction testing operations are summarized below.
As we understand the proposed improvements onsite include rebuilding retaining wall and regrading slope.
SITE OBSERVATION
Our site observation for the 4 foot country manor retaining wall included observation of the excavation for the
gravel leveling pad below grade, placement of block, conformation of grid orientation and grid length and
placement of the wall backdrain. Please note the wall backdrain runs in a separate tightline and ties into the
surface area drain line just behind the sidewalk and the core in the street. An earthen swale at the top of the
wall flows away from wall to installed area drains. As part of our onsite observation and testing we observed
and tested the benching and rebuild of the 1.5:1 slope above the wall. The 1.5:1 slope is constructed with
horizontal grid. The soil was compacted with a remote sheepsfoot vibratory roller and wacker. No moisture
conditioning was necessary during construction. Based upon our observations of the wall and slope
construction, the project has been built with the overall design intent of the project retaining wall plans.
FIELD AND LABORATORY TESTING
Limited field density tests were performed in accordance with D2922 (Nuclear Gauge Method). Our test
results indicate that, in the locations tested, soils have been compacted to at least 90% relative compaction,
as determined by ASTM D1557, (Procedure A). The reported test results are representative of the soil
conditions at the locations tested. Our observation and field density testing methods are in accordance with
normally accepted procedures. The accuracy of the relative compaction values are subject to the precision
limitations of the ASTM test methods. The accuracy of the maximum dry density determination (ASTM
D1557) is discussed in the 2003 Annual Book of ASTM Standards, Section 4, Volume 04.08, entitled, Soil and
Rock; Building Stones. Variations of relative compaction values should be expected, laterally and vertically,
from actual test locations.

TESTING SUMMARY
In general, it is our opinion, based on the placement procedure and the test data collected, the fill soils tested,
at the locations tested, were compacted to a minimum of 90% relative compaction (based on ASTM 01557,
Procedure A).
If you have any questions regarding this report, or if we can be of further service, please do not hesitate to
contact us. We hope the report provides you with the necessary information to continue with the development
of the project.

Re: Keystone Retaining Wall to be located at 2742 Abejorro Street, Carlsbad, California.
Subject: Soils Recommendations
We have prepared the following recommendations in consideration of the construction of a new
approximately 4 foot high keystone block wall along the toe of the existing slope. In addition we anticipate
removal of the existing keystone blocks in the area of the upper slope and the restoration of the existing
1.5:1 slope in the area of block removal. The following earthwork recommendations herein should be
implemented during the backfill of the proposed new wall.
EARTHWORK
We anticipate site earthwork will include the placement of backfill for the proposed keystone country
manor retaining wall and the restoration of the 1.5:1 slope in the area of existing wall removal, as indicated
on plans. All utilities shall be marked-out prior to the start of work.
1. Site Preparation
Prior to any grading areas of proposed improvement should be cleared of surface and
subsurface debris (including organic topsoil). Removed debris should be properly
disposed of off-site prior to the commencement of any fill operations. Holes resulting
from the removal of debris, existing structures, or other improvements which extend
below the undercut depths noted, should be filled and compacted using on-site material or
a non-expansive import material. The tree onsite shall be removed, along with all roots,
and shall be properly disposed of (see plans).
2. Fills
All newly placed backfill material should be brought to +2% of optimum moisture content,
and re-compacted to at least 90 percent relative compaction in the area of wall backfill.
The area of slope reconstruction in the area of the backcut shall be include geogrid
reinforcement, placed at 2 feet on-center, vertically, with a minimum length of two feet. In
the area where the removed keystone block above, the slope shall be re-configured to the
1.5:1 original design intent. The shallow fills placed, anticipated to be approximately 1
foot or less shall be re-compacted to at least 95 percent relative compaction (based on
ASTM D1557) (see plans). Surficial, loose or soft soils exposed or encountered during
grading (such as any undocumented or loose fill materials) should be removed to
competent material.
EDG Project No. 104704-1,2,4
Z:\2010\PEDICINI, DAVE, 104704-4\REPORTS, LETTERS\SOILS LETTER 7-15-10.wpd
Fills should generally be placed in lifts not exceeding 8 inches in thickness. If the import
of soil is planned, soils should be non-expansive (El<30) and free of debris and organic
matter. Prior to importing, soils should be visually observed, sampled and tested at the
borrow pit area to evaluate soil suitability as fill. Where new foundations extend across a
retaining wall backfill wedge footings shall be deepened through fill to competent
sandstone.
3. Slopes
Permanent slopes may be cut to a face ratio of 1.5:1 (horizontal to vertical). Permanent
fill slopes shall be placed at a maximum 1.5:1 slope face ratio. All temporary cut slopes
shall be excavated in accordance with OSHA requirements. Subsequent to grading
planting or other acceptable cover should be provided to increase the stability of slopes,
especially during the rainy season (October thru April).
SURFACE DRAINAGE
Adequate drainage precautions at this site are imperative and will play a critical role on the future
performance of the dwelling and improvements. Under no circumstances should water be allowed to
pond against or adjacent to foundation walls, or tops of slopes. The ground surface surrounding proposed
improvements should be relatively impervious in nature, and slope to drain away from the structure in all
directions, with a minimum slope of 2% for a horizontal distance of 7 feet (where possible). Area drains or
surface swales should then be provided to accommodate runoff and avoid any ponding of water. Any
french drains, backdrains and/or slab underdrains shall not be tied to surface area drain systemsAII drains
should be kept clean and unclogged, including gutters and downspouts. Area drains should be kept free
of debris to allow for proper drainage.
Over watering can adversely affect site improvements and cause perched groundwater conditions.
Irrigation should be limited to only the amount necessary to sustain plant life. Low flow irrigation devices
as well as automatic rain shut-off devices should be installed to reduce over watering. Irrigation practices
and maintenance of irrigation and drainage systems are an important component to the performance of
onsite improvements.
During periods of heavy rain, the performance of all drainage systems should be inspected. Problems
such as gullying or ponding should be corrected as soon as possible. Any leakage from sources such as
water lines should also be repaired as soon as possible. In addition, irrigation of planter areas, lawns, or
other vegetation, located adjacent to the foundation or exterior flat work improvements, should be strictly
controlled or avoided.
CONSTRUCTION OBSERVATION AND TESTING
The recommendations provided in this report are based on surface observations at the site and
knowledge of local conditions. Interpolated subsurface conditions should be verified in the field during
construction. The following items shall be conducted prior/during construction by a representative of
Engineering Design Group in order to verify compliance with the geotechnical and civil engineering
recommendations provided herein, as applicable. The project structural and geotechnical engineers may
upgrade any condition as deemed necessary during the development of the proposed improvement(s).
1. Attendance of a pre-grade/construction meeting prior to the start of work.
2. Observation of excavation for gravel leveling pad, backdrain, grid reinforcement, pipe outlets, and
as otherwise more specifically described in the special inspection section of the project plans.

3. Testing of any fill placed, including retaining wall backfill and utility trenches.
4. Field observation of any "field change" condition involving soils.
5. Walk through of final drainage detailing prior to final approval.
The project soils engineer may at their discretion deepen keyways, footings or locally recommend
additional geogrid reinforcement to upgrade any condition as deemed necessary during site observations.
The field inspection protocol specified herein is considered the minimum necessary for Engineering
Design Group to have exercised "due diligence" in the soils engineering design aspect of this building.
Engineering Design Group assumes no liability for structures constructed utilizing this report not meeting
this protocol.
Engineering Design Group requires a minimum of 48 hours notice to mobilize onsite for field observation
and testing.
MISCELLANEOUS
Data for this report was derived from surface observations at the site and knowledge of local conditions.
The recommendations in this report are based on our experience with grading of this type. We believe
that this information gives an acceptable degree of reliability for anticipating the behavior of the proposed
1.5:1 slope however, our recommendations are professional opinions and cannot control nature, nor can
they assure the soils profiles beneath or adjacent to those observed. Therefore, no warranties of the
accuracy of these recommendations, beyond the limits of the obtained data, is herein expressed or
implied. This report is based on the investigation at the described site and on the specific anticipated
construction as stated herein. If either of these conditions is changed, the results would also most likely
change.
Man-made or natural changes in the conditions in the area of improvement can occur over a period of
time. In addition, changes in requirements due to state of the art knowledge and/or legislation, are rapidly
occurring. As a result, the findings of this report may become invalid due to these changes. Therefore,
this report for the specific site, is subject to review and not considered valid after a period of one year, or if
conditions as stated above are altered.
It is the responsibility of the owner or his representative to ensure that the information in this report be
incorporated into the plans and/or specifications and construction of the project. It is advisable that a
contractor familiar with construction details typically used to deal with the local subsoil and seismic
conditions, be retained to build the structure.
If you have any questions regarding this report, or if we can be of further service, please do not hesitate to
contact us. We hope the report provides you with necessary information to continue with the development
of the project.
Sincerely,
ENGINEERING DESIGN GROUP
