In accordance with your request and authorization, LGC Valley, Inc. (LGC) has provided geotechnical
services during the mass grading operations for Planning Areas PA-i through PA-3, PA-5, PA-6, PA-9,
PA-b, PA-13, and PA-23A through PA-23C of the Robertson Ranch project (Carlsbad Tract No. 13-
03) located within the City of Carlsbad, California. This as-graded report of mass grading summarizes
our observations, field and laboratory test results, and the geotechnical conditions encountered during
grading of the subject site. Planning Areas PA-4, PA-7, PA-8, and PA- 11 of Robertson Ranch were
graded at the same time as the remainder of the site but are not included in this report. The results of
our geotechnical observation and testing services, as well as, our conclusions and recommendations
concerning the as-graded conditions of PA-4, PA-7, PA-8, and PA- il of Robertson Ranch have or will
be presented under separate cover.
The mass grading operations for Planning Areas PA-1 through PA-3, PA-5, PA-6, PA-9, PA-10, PA-
13, and PA-23A through PA-23C of the Robertson Ranch project were performed in general
accordance with previously published project geotechnical reports (Appendix A), geotechnical
recommendations made during the course of grading, and the City of Carlsbad grading requirements.
As of this date, the mass grading operations for the subject areas are essentially complete.
The Rough Grading Plans for the Robertson Ranch project, prepared by O'Day Consultants (O'Day,
2014a), were utilized as a base map to present the as-graded geotechnical conditions and approximate
locations of the field density tests. The As-graded Geotechnical Map (Plates IA through IF) and the
Field Density Test Location Map (Plates 2A through 2F) are presented in the pocket at the rear of the

1.1 Project Description
The Robertson Ranch development is approximately 211 acres in size and is located on the
north side of El Camino Real between Tamarack Avenue on the west and Cannon Road on
the east in the northeastern portion of the City of Carlsbad, California. The irregular-shaped
site is bounded by El Camino Real on the south, Tamarack Avenue on the northwest,
existing residential developments on the north and east, and by Cannon Road on the
southeast.
The proposed Robertson Ranch development consists of a number of Planning Areas
including PA-1 through PA-11,PA-13, and PA-23A through PA-23C. Based on our
understanding, PA-1 and PA-23A through PA-23C are designated open spaces areas; PA-2
will be a future community facility; PA-3, PA-5, PA-6, PA-9, PA-b, and PA-13 are single-
family residential communities; PA-4 will be a community center and pool complex; PA-7
and PA-8 will be a multi-family residential development with an assisted-living senior
housing center; and PA- ii will be a retail/commercial site.

2.0 SUMMARY OF MASS-GRADING OPERATIONS
Mass grading of the subject site began on September 15, 2014 and was essentially completed as of May
15, 2015. The grading operations were performed under the observation and testing services of LGC
Valley, Inc. Our field technicians were onsite on a full-time basis during the grading operations while
our field and project geologists were on-site on a periodic basis. The mass-grading operations included:
Removal and off-site disposal of vegetation and miscellaneous debris;
The removal of potentially compressible soils including alluvium, colluvium, topsoil,
undocumented fill, and weathered soils to competent terrace deposits or formational material;
Overexcavation of cut/fill transition conditions within the limits of the residential lots;
Overexcavation of buried cut/fill transition conditions such that the resulting fill differential
beneath the proposed building pads was less than a 3:1 (maximum fill thickness to the
minimum fill thickness);
Overexcavation of cut lots due to expansive soils lots and/or very dense moderately cemented
sandstone;
The excavation of stability fill keys;
Preparation of areas to receive fill;
The placement of subdrains in the canyon bottoms and along the heel of the stability fill
keys;
Installation of stabilization fabric and rock layer over left-in-place saturated alluvium;
The placement of compacted fill soils and excavation of cut creating the lots, streets, sheet-
graded pads and adjacent slopes; and
Installation of settlement monuments in deep fill areas (considered to be fills greater than
40 feet below design finish grades).
The mass-grading operations consisted of the excavation of up to approximately 50 feet of cut and
placement of a maximum thickness of approximately 75 feet of fill. The as-graded geotechnical
conditions are presented on the As-Graded Geotechnical Map (Plates 1 A through IF).
2.1 Site Preparation and Removals
Prior to grading, the site was cleared of light vegetation, trash, prior farming debris, and other
miscellaneous debris and the material was disposed of at an offsite facility. Undocumented fill,
topsoil, alluvium, colluvium, weathered terrace soils, and formational material were removed to
competent material (i.e. dense unweathered terrace or formational material). Remedial
removals on site, below the existing ground surface, generally ranged from approximately 3 to
15 feet with a maximum depth of remedial removal of up to approximately 40 feet associated
with the main north-south trending canyons in the southwestern and southeastern portions of
PA-7 and in the central portion of PA-8.
Following the remedial removals or overexcavations, areas to receive fill were scarified
approximately 6- to 12-inches; moisture-conditioned, as needed, to obtain a near-optimum
Project No. 133023-03 Page 4 June 28, 2016
I
I moisture content; and compacted to a minimum 90 percent relative compaction (for fills of
approximately 40 feet or less from design grades) or 93 percent relative compaction (for
I engineered fill below approximately 40 feet from design finish grades). Compaction was
determined by ASTM Test Method D6938 (i.e. the nuclear gauge method).
2.2 Saturated Alluvial Mitigation
I Based on geologic mapping and observations made during the remedial grading removals
within Planning Area PA-2 and in the northwestern portion of Robertson Road (between
approximate Station Number 10+50 and 12+25), shallow groundwater was encountered at an
I approximate depth of 5 to 6 feet below the existing ground surface within the alluvial soils.
This ground water condition is assumed to be a perched ground water within the lower section
of the on-site alluvial soils. Recommendations were made to remove the alluvial soils to within
I i to 2 feet of the groundwater elevation, install a stabilization fabric (i.e. Mirafi 600x) along the
removal bottom and then place sandy compacted fill to the design grades (LGC, 2015). In areas
where standing water was present or where significant pumping and rutting occurred, a 1- to 2-
I foot thick rock layer was placed in the removal bottom prior to the placement of the
stabilization fabric. The rock layer consisted of 6-inch minus rock with sand.
I
The approximate locations of the rock layer and stabilization fabric include the west side of
Robertson Road between Station 10+65 and 12+85; and the north-central and northeast side of
PA-2. The approximate locations of the stabilization fabric include the east side of Robertson
I Road between Station 10+65 and 12+30, the west side of Robertson Road between Station
12+85 and 14+00, and the southeast side of PA-2.
2.3 Stability Fills
Stability fills were constructed to stabilize the exposed blocky claystone/siltstone and/or
adverse (i.e. out-of-slope) geologic conditions present within the Santiago Formation. The
stability fill keys were excavated to a width ranging from 15 to 25 feet and a minimum depth of
3 to 5 feet below the toe-of-slope. The keyway bottom was angled at least 2 percent into-the-
slope. The stability fill front cuts were excavated near vertical while the backcuts were
excavated at an approximate 2:1 or 1:1 (horizontal to vertical) slope inclination. Subdrains were
places along the heel of the stability fill keys and are discussed in Section 2.4.
Stability fills were excavated along the proposed slope on; 1) the northeast sides of Lots 68
through 70 of PA-3; 2) the north sides of Lots 92 through 95 of PA-3; 3) south of Lots 135
through 145, 156, and 157 of PA-3; 4) the northwest sides of Lots 158 through 163 and 245 of
PA-6; 5) the northwest sides of Lots 170 through 182 of PA-6; 6) southeast of Lots 185 through
193 of PA-6; 7) southeast and east of Lots 198 through 210 of PA-6; 8) the west side of Lots
212 through 223 of PA-6; 9) the north side of Lots 252 through 264, 277 through 281, and 282
through 286 of PA-9; 10) the north side of Lots 300, 301 and 328, 302 through 307 and 329,
317 through 319, and 320 through 323 of PA-10; 11) the east side of Robertson Road between
approximate Station No. 15+75 to 18+00 in PA-1; and 12) the north side of PA-11. The

approximate locations of the stability fill keys are presented on the As-graded Geotechnical
Map (Plates 1A through IF).
The stability fill keys recommended in the project preliminary geotechnical report (LGC,
2014a) on the north sides of Lots 82 through 87 and 150; Lots 88 through 91 and 151; Lots 107
through 110 and 152; Lots 111 through 114 and 153; Lots 127 through 130 and 154; and Lots
131 through 134 and 155 were not constructed during the mass grading operations. Instead, the
slopes on these lots were completely overexcavated removing the proposed cut and replacing
the slopes with compacted fill. The overexcavation extended to a depth of at least 5 feet below
the proposed toe-of-slope with a removal bottom angled no steeper than a 3:1 (horizontal to
vertical).
2.4 Subdrain Installation
Canyon and stability fill subdrains were installed under the observation of a representative of
LGC in general accordance with the approved geotechnical report (LGC, 2014a) and
geotechnical recommendations made during the course of the mass grading operations. After
the potentially compressible material in the canyons were removed to competent material or
when compacted fill was placed over competent material to obtain flow to a suitable outlet
location, a subdrain was installed along the canyon bottom. The canyon subdrains consisted of
a 6-inch diameter perforated pipe surrounded by a minimum of 9-cubic feet (per linear foot) of
crushed 3/4-inch gravel wrapped in Mirafi 140N filter fabric. Canyon subdrains were installed
in the western canyon along the east side of PA-3; in the small canyon in the middle of PA-7;
the main canyon in PA-5 through PA-8; the upper end of the south canyon in PA- 11; and in the
two small canyons in the southeast portion of PA- 10.
In addition to the canyon subdrains, subdrains were also installed along the bottom backside of
the stability fill keys. The stability fill subdrains consisted of a 4-inch diameter perforated pipe
surrounded by a minimum of 3-cubic feet (per linear foot) of clean 3/4-inch gravel wrapped in
Mirafi 140N filter fabric. Stability fill key subdrains were installed in each of the keys
mentioned in Section 2.3.
The canyon and stability fill subdrains were placed with a minimum 1-percent fall (2-percent or
greater where possible) to a suitable outlet location. The locations of the subdrains placed
during the mass-grading operations for the project were surveyed by the project civil engineer.
The subdrain locations are presented on the As-graded Geotechnical Map (Plates IA through
iF).
As indicated on the as-graded geotechnical map, three (3) canyon subdrains and five (5)
stability fill subdrains were ultimately outletted into adjacent storm drain structures or the storm
drain pipe. Four of these outletted subdrains are located on the north side of El Camino Real
(on the south side of Planning Area PA-3) and four are located along Gage Drive in Planning
Areas PA-9 and PA-b.
Project No. 133023-03 Page 6 June 28, 2016
I
I 2.5 Fill Slope Keys
I Prior to the placement of fill slopes that were planned above natural and/or cut areas on the site,
a fill slope key was constructed. The fill slope keys were excavated at least 2 feet into
competent soil along the toe-of-slope and constructed approximately 15 feet wide with the key
I bottom angled a minimum of 2 percent into-the-slope. Fill slope keys constructed on site during
the mass grading operations included the slopes: 1) northwest of Lots 63, 71, and 82 of PA-3;
2) east of Lots 226 through 243 of PA-6; 3) west of Lots 252, 265, 276, and 288 of PA-9 and
I Lots 299, 308, 317, and 325 of PA-10; 4) east of Edinburgh Drive, Lots 275, 287, and 298 of
PA-9 and Lots 307, 316, 324, and 330 of PA-10; and 5) the west side of Robertson Road
approximately from Station 14+00 to 15+90 west of PA-3.
2.6 Cut/Fill Transition Conditions
The cut portion of lots that exposed the cut/fill transition was overexcavated a minimum of 5
feet below finish pad grade. Overexcavation of the building pad was performed to mitigate the
transitional condition and related adverse effects of differential settlement that can result due to
this underlying condition. The limits of the overexcavations were made at least 5 feet outside
the anticipated building limits (or building footprint). To reduce the potential of a perched
ground water condition within the transition lots, the pads were overexcavated with a minimum
1-percent fall in the overexcavation bottom toward the fill. During the mass grading operations,
remedial grading was also performed so that the fill differential beneath the proposed building
pads was less than a 3:1 (maximum fill thickness to the minimum fill thickness).
Lots that were overexcavated due to a cut/fill transition condition include Lots 29 through 32,
48, and 54 of PA-5; Lots 63, 68, 69, 71, 72, 77, 82, 88, 100, 112, 124, 133, and 135 through 145
of PA-3; Lots 164, 165, 169 through 171, 189, 198 through 207, and 226 through 244 of PA-6;
Lots 252, 253, 266 through 269, 275, 277 through 279, 287, 294, and 295 of PA-9; and Lots
300, 301, 305 through 307, 309 through 312, 317, 318, and 323 of PA-10.
2.7 Overexcavation of Cut Lots
During the mass grading of the Robertson Ranch project, the overexcavation of cut lots was
performed in order to mitigate potential adverse conditions including: 1) well-cemented
sandstone beds (or concretion layers) and very dense or hard Santiago Formation at or near
finish grade which could create difficulties during future excavations on the lots; and 2)
potential highly expansive soils at finish grade that would require significant post-tension
foundation designs. The cut lots that contained these conditions were overexcavated a
minimum of 5 feet below finish pad grade and replaced with compacted fill. In order to
minimize potential ponded ground water conditions on the overexcavation bottom, the lots
were overexcavated with a minimum fall of 1- to 2-percent toward the front of the lot or deeper
fill area.
Project No. 133023-03 Page 7 June 28, 2016
P
I Lots overexcavated due to well-cemented sandstone or dense Santiago Formation included Lots
39 through 47 and 60 of PA-5; and Lots 158 through 163, 183, 184, 212, and 213 of PA-6. Lots
I overexcavated due to expansive clayey soils included Lots 64 through 67, 70, 73 through 76,
83 through 87, 92 through 99, 105 through 111, 115 through 123, and 127 through 132 of
PA-3; Lots 180 through 182 of PA-6; Lots 254 through 264, 270 through 274, 280 through
286, 292, 293 of PA-9; and Lots 319 through 322 of PA- 10.
2.8 Toxanhene Imnacted Soil Removal and Burial
Previous studies by GeoSoils (GeoSoils, 2007b, 2007c, 2010a, 2010b, 2010c, and 2011b),
indicated that approximately 95,000 cubic yards of pesticide impacted soils were present on the
site and that these soils needed to be remediated during the mass grading operations. The
County of San Diego Department of Environmental Health (DEH) was the review and approval
I agency and the case opened in March 2011 as "Rancho Costera, El Camino Real and
Tamarack, Carlsbad"; DEH File No. H39768-001. Documents related to the case can be found
on the web site "Geotracker" using the case file number on the advanced search page of the
I site. The site can be found at "geotracker.waterboards.ca.gov".
Based on the approved site Property Mitigation Plan (PMP), the proposed mitigation measures
I included the excavation of the toxaphene impacted soil and placement of the soils within the
on-site street right-of-ways in planned fill areas (Havasu Consulting, 2014). The approved PMP
presented a remediation approach to remove the toxaphene impacted soil where concentrations
I existed at or above 460 jig/kg (i.e. the threshold value requiring remediation) within the
property. The PMP also presented an approach designed to place the toxaphene impacted soils
in designated areas within the street right-of-ways of the site at depths greater than 12 feet
I below the finish surface of the street or 2 feet below the deepest utility (if the utility line was
greater than 10 feet in depth). Based on the highest anticipated groundwater elevation of
approximately 45 feet mean sea level (MSL), no impacted soil was to be placed below an
I
elevation of 50 feet MSL, thereby providing a minimum soil cap of 5 feet above the highest
anticipated groundwater elevation. A marker material was to be placed over the final level of
toxaphene-impacted soil to identify the location of the impacted soil.
I Based on soil sampling results from previous subsurface investigations (Havasu Consulting,
2014), soils to depths from 0 to 4 feet below the ground surface were expected to be impacted
I
above the site clean-up level. Nine (9) designated areas (i.e. Areas A through I) on the site were
identified by GeoSoils as being impacted with toxaphene. Remedial excavation work
commenced on September 29, 2014 and was completed by November 7, 2014. The remediation
I
operations typically consisted of: 1) one dozer and a water truck ripping and moisture-
conditioning the impacted soil removal areas prior to removal; 2) three to six scrapers
excavating the impacted soil and hauling it to the burial areas; and 3) the same dozer and/or a
I
second dozer, the same water truck and the scrapers mixing the soil, adding additional water,
and compacting the soil to the project geotechnical recommendation of 90 percent relative
compaction. Observation and field density testing of the compacted soil was performed by a
senior field technician from LGC (Havasu, Consulting, 2016).
Project No. 133023-03 Page 8 June 28, 2016
The excavated impacted soils were placed in three burial areas on the site in the south and
central portions of the site and included a portion of West Ranch Street; Robertson Road;
Wellspring Street; and Nelson Court. Upon completion of the burial areas, the tops and upper
sides of the impacted soil was covered with a dark gray filter fabric. Prior to the placement of
the impacted soil and after the fabric was placed, the burial areas were surveyed by the project
civil engineer. The approximate limits of the burial locations are shown on the As-Graded
Geotechnical Map (Plates 1A through IF). A comprehensive discussion of the toxaphene
impacted soil remediation operations is presented in the report entitled "Final Remedial
Summary Report", dated March 31, 2016 (Havasu Consulting, 2016).
Upon the completion of the impacted soil removals in the nine removal areas, random
I
verification/confirmation sampling was performed. The test results demonstrated that: 1) the
toxaphene levels at the base of the removal excavations were non-detected or below the
threshold values requiring remediation; and 2) that the toxaphene-impacted soil was removed.
I
Subsequent to the grading of the site in the areas of the previously impacted soil and burial
areas, 15 random post-grading soil samples were obtained and tested for toxaphene. The test
results indicated the samples did not detect any toxaphene (Havasu Consulting, 2016).
2.9 Fill Placement and Compaction
After processing the areas to receive fill, native soil was generally spread in approximately 8-
inch loose lifts, moisture-conditioned as needed to attain near-optimum moisture content, and
compacted to at least 90 or 93 percent of the maximum dry density determined in accordance
with ASTM Test Method D1557. Fill soils less than 40 feet below the design finish grades
were compacted to a minimum 90 percent relative compaction while fill soils greater than 40
feet below the design finish grades were compacted to a minimum 93 percent relative
compaction. Compaction was achieved by use of heavy-duty construction equipment. Areas of
fill in which either field density tests indicated less than 90 or 93 percent relative compaction or
the soils exhibited nonuniformity and/or showed an inadequate or excessive moisture content,
were reworked, recompacted, and retested until a minimum 90 or 93 percent relative
compaction and near-optimum moisture content was achieved.
2.10 Laboratory Testing
Maximum dry density tests of representative on-site soils were performed (by others during the
previous investigation and by LGC during the current mass-grading operations) in general
accordance with ASTM Test Method D1557. Representative expansion potential, soluble
sulfate content, and corrosion suite tests were performed on representative samples of the finish
grade soils on the residential lots.
The test results indicate the representative finish grade soils have: 1) a very low to high
expansion potential (per U.B.C. Standard No. 18-I-B); 2) a negligible to severe soluble sulfate
content per ACI criteria (ACT 318R-08 Table 4.3.1); 3) are moderately to severely corrosive to
buried metals based on the minimum soil resistivity values; and 4) are corrosive to buried
Project No. 133023-03 Page 9 June 28, 2016
metals and reinforcing steel in concrete based on the chloride concentrations. The laboratory
test procedures and laboratory test results are presented in Appendix B.
2.11 Field Density Testing
Field density testing was performed using the Nuclear-Gauge Method (ASTM Test Method
D6938). The approximate test locations are shown on the Field Density Test Location Map
(Plate 2). The results of the field density tests are summarized in Appendix C.
The field density testing was performed in general accordance with the applicable ASTM
standards and the current standard of care in the industry. In-situ soil density testing is
intended to verify the effectiveness of the earthmoving operation in general and is performed
on a spot-check basis; as such, some variations in relative compaction should be expected
from the results documented herein.
2.12 Graded Slopes
Manufactured fill and cut slopes within the subject area were surveyed by the civil engineer and
constructed with slope
inclinations of 2:1 (horizontal to vertical) or flatter. Permanent graded
fill slopes within the subject area range from less than 5 to approximately 90 feet in height.
Permanent cut slopes are approximately 5 to 10 feet in height or less.
The on-site fill and cut slopes are considered grossly and surficially stable from a geotechnical
standpoint (under normal irrigation/precipitation patterns) provided the project geotechnical
recommendations are incorporated into the fine-grading, post-grading, construction, and
post-construction phases of site development.
2.13 Settlement Monuments
The compacted fills within Robertson Ranch range from 0 to approximately 75 feet in depth.
A total of seven settlement monuments were installed/constructed at representative locations
in the deep fill areas in general accordance with the project geotechnical report (LGC,
2014a), following the completion of the majority of fill placement operations in the deep fill
areas. However, five of these settlement monuments were placed within deep fill areas of
PA-7 and PA-8. The settlement monuments were installed in deep fill areas ranging from 50
to 75 feet in thickness. The approximate location of the settlement monuments are shown on
the As-Graded Geotechnical Map (Plates 1A through IF).
I
The settlement monuments were surveyed by O'Day Consultants. Based on the settlement
monument readings to date of the two monuments in Planning Area PA-6 and in Gage Drive
between Planning Areas PA-6 and PA-10 (i.e. Settlement Monuments #6 and #7), settlement
of the fills has been minimal. Based on almost 14 months of survey readings, the settlement
I of the deep fill in the vicinity of Settlement Monument #6 is less than 1/10-inch of
Project No. 133023-03 Page 10 June 28, 2016
settlement. In the vicinity of Settlement Monument #7, the deep fill has settled about 1/2-
inch over a five (5) month period. The accuracy of the settlement survey readings is +1- 1/4-
inch. As a result, it is our professional opinion that the primary and secondary consolidation
of deep fills is within acceptable limits.
2.14 Verdura Retaininje Walls
During the mass grading operations, a number of Verdura mechanically-stabilized retaining
walls were constructed on the site. Prior to the construction of the retaining wall, the footing
excavation and soil conditions was observed by a LGC representative and found to be in
general accordance with the design parameters and recommendations assumed in the project
geotechnical report and retaining wall design parameters (LGC, 2014, 2014c, and 2015j). In
addition, a backdrain was placed along the back bottom side of the retaining wall key and
outletted at the slope face below the wall. Field density testing was also performed during the
backfill operations of the retaining walls. The field density test results indicated that the
backfill soils were compacted to a minimum 90 percent relative compaction (based on
ASTM Test Method D1557). The field density test results are presented in Appendix C.
Verdura retaining walls were constructed at the following locations: 1) above and below the
I trail on the southwest and south sides of Lot 92 of PA-3; 2) in the middle of the large south-
facing slope on the south sides of Lots 135 through 145, 156, and 157 of PA-3; 3) in the
middle of the east-facing slope east of Lots 240 through 243 of PA-6; 4) on the northwest
I side of the trail adjacent to Lot 34 of PA-5; and 5) on the northwest side of the trail adjacent
to Lot 36 of PA-5.
I 2.15 Animal Crossing on Gage Drive
I
As part of the development of the Robertson Ranch project, an animal crossing was proposed
along the bottom of the canyon that a portion of Gage Drive crossed between Planning Areas
PA-6 and PA-10. As designed and built, the structure consists of a 18-foot diameter, 3-gauge
I
(0.249-inches) thick galvanized Contech "Multi-Plate" Corrugated Metal Pipe Structure with
a design life of at least 100 years. The structure has an approximately 6-foot fall from the
northwest to southeast ends of the pipe (i.e. a fall of approximately 2.5 percent). The
I
structure is approximately 225 feet in length with cast-in-place concrete headwalls at both
ends and has up to 30 to 35 feet of compacted fill placed over the top of the structure. The
upstream and downstream headwalls are approximately 36 and 27 feet in height,
I
respectively.
Grading and construction of the structure was started on June 29, 2015 and essentially
I
completed by November 2015. Prior to the construction of the structure, all of the alluvium
was removed beneath the proposed structure and replaced with sandy fill soils compacted to
either 93 percent relative compaction for the fill soils greater than 40 feet in depth or 90
percent relative compaction for fill soils less than 40 feet from the design finish grade
I elevation.
Project No. 133023-03 Page 11 June 28, 2016
I
A 2-foot thick layer of select material (i.e. 'rock dust' consisting of sand-sized rock chips)
I was placed below the bottom of the pipe as a bedding layer. The bottom of this select
material layer was angled approximately 2-percent from west to east. Along the east side of
the animal crossing alignment, a subdrain consisting of a 4-inch diameter perforated pipe
I with 4-cubic feet of crushed rock (per linear foot) and surrounded by a Mirafi 140N filter
fabric was placed and outletted into the rock riprap on the downhill (or southeast side) of the
animal crossing. The subdrain has a fall of approximately 2.5 percent.
After the multi-plate corrugated metal pipe was bolted together, the concrete headwalls on
both side of the structure were constructed and allowed to cure. After the curing period, a 2-
foot thick layer of the 'rock dust' was placed and compacted around the pipe. At the same
time, an additional 4-foot wide/thick layer of the select on-site sandy soils was placed outside
of the 'rock dust' layer until the pipe was completely covered with a 6-foot thick layer of
select material. Finally, on-site sandy soil was placed over the pipe until the design street
subgrade or slope face was achieved.
Based on the animal crossing design (LGC, 2015e), the bottom inside 4 feet of the corrugated
pipe was coated with a 50-mil thick bituminous material. A perforated 4-inch diameter
subdrain pipe inside a filter fabric sock was placed along the bottom of the pipe. The upper
end of the subdrain was capped, while the lower end was outletted beyond the downhill side
of the animal crossing structure. Two 2-foot tall cutoff walls were placed inside the
corrugated pipe to minimize erosion of the select material inside the pipe. Three (3) feet of
stabilized material was then placed inside the pipe for the animals to walk across.

3.0 ENGINEERING GEOLOGIC SUMMARY
3.1
3.2
As-Graded Geoloj'ic Conditions
The geologic or geotechnical conditions encountered during the mass grading of the site were
essentially as anticipated; however, the alluvium in the lower portions of the main tributary
canyons along the north side of El Camino Real were significantly deeper than anticipated
based on data from the project preliminary geotechnical investigations (Appendix A). In
addition, the questionable landslide previously mapped in the northeastern portion of the site
was not encountered during the mass grading operations; but was observed to consist of
formational material dipping the opposite direction than the typical bedding on the remainder of
the site. Finally, a shallow perched groundwater condition was present in the area of Planning
Area PA-2 that precluded complete removal of the saturated alluvial soils. Instead of the
complete removal of the alluvium, a stabilization fabric underlain in places with a layer of rock
was placed on top of the saturated alluvium prior to the placement of fill. A comprehensive
summary of the geologic conditions (including geologic units, geologic structure, and faulting)
is presented below.
Geoloic Units
The geologic units encountered during the mass grading operations consisted of documented
and undocumented fill, topsoil, colluvium, alluvium, terrace deposits and the Santiago
Formation. Due to the potentially compressible nature of the desiccated documented fill,
undocumented fill, topsoil, colluvium, alluvium, and weathered formational material, these
soils were removed to competent material during the mass grading operations. The as-graded
geologic units encountered during the grading operations are discussed (youngest to oldest)
below. The approximate limits of the mapped geologic units is presented on the As-Graded
Geotechnical Map (Plates 1A through iF).
Documented Fill
Previous grading of a portion of Planning Areas PA-9, PA- 11, PA-13, PA-23C, and the
widening of the north side of El Camino Real west of Cannon Road has created a number
of fill areas along the southern portion and northeast corner of the site. These fills generally
consisted of clayey to silty sands and sandy clays derived from native soils and were found
to be moderately to well compacted and damp to moist. Prior to the placement of fill in
these areas, the dry and desiccated upper 1 to 3 feet of the documented fill was removed to
competent material.
Undocumented Fill
Undocumented fill soils were observed in a number of places on the site. The
undocumented fills were generally associated with the grading of the onsite dirt roads,
retention basins, and prior farming activities. These fill soils ranged from less than 1 to
Project No. 133023-03 Page 13 June 28, 2016
approximately 10 feet in depth, and generally consist of dry to damp, loose or soft, sand and
sandy clay. All existing undocumented fill located within the limits of grading were
removed to competent formational material.
Topsoil
A relatively thin veneer of topsoil was removed from the higher elevations of the site. The
topsoil, as encountered, consisted predominantly of a dark brown, damp to moist, loose,
sandy clay and minor clayey to silty sand. The topsoil was generally massive, porous, and
contained scattered roots and organics. Topsoil removal thicknesses were on the order of 1
to 4 feet thick. During the grading operations, the topsoil was observed to have been
removed within the limits of grading.
Alluvium and Colluvium
Alluvium and colluvium was encountered during the mass grading operations in the
canyons and on the lower portion of the hillsides on the site. The alluvium and colluvium
typically consisted of light brown to dark brown, damp to moist, silty fine sands, sandy
clays and clayey sands derived from the terrace deposits and the formational material and
were found to be low to highly expansive, porous, and contained scattered organics.
Removals of up to approximately 40 feet in depth (typical removals were on the order of
less than 10 to 15 feet) were made within the alluvial soils present in the main tributary
canyons in the southern portion of the site along the north side of El Camino Real within
Planning Areas PA-2, PA-3, PA-6 through PA-8, PA-1 1, and PA-23A through PA-23C.
Removals of the colluvium, on the order of 2 to 6 feet, were made on the middle and
lower portions of the hillsides on the site.
Terrace Deposits
I
Terrace or older alluvial flood-plain deposits were encountered in the south-central and
southeastern portion of the site within Planning Areas PA-7, PA-8, PA- 11, PA-13, and PA-
23C. As encountered, these soils consisted of silty fine to medium sand, clean sands, and
I sandy to silty clays with minor gravels. The nature of the contact between the terrace
deposits and formational material, where observed, was a relatively sharp contact with a
near horizontal orientation. Along the northern contact, east of PA-7, the terrace deposits
appeared to be deposited against a river bank with a moderately steep contact up to 5 to 10
1 feet in height.
I
6) Santiago Formation
The Tertiary-aged Santiago Formation, as encountered during the mass grading operations,
I
consisted primarily of massively bedded sandstones to cross-bedded silty sandstones and
generally consisted of pale gray, pale brown and pale orange brown (where iron-oxidized
stained), damp to moist, dense to very dense, silty very fine to medium grained sandstone.
Several of these sandstone beds are friable to well-cemented fossiliferous sandstone beds.
I Minor beds of claystones/siltstones were present in the lower elevations of the formation
Project No. 133023-03 Page 14 June 28, 2016
and were generally olive-green to gray (unweathered) and orange brown (where oxidized),
damp to moist, stiff to hard, moderately weathered, and occasionally fractured and
moderately sheared.
3.3 Geologic Structure
The general structure of the formational material appears to be slightly dipping less than 15 to
20 degrees to the west/southwest. Based on our geologic mapping during the mass grading
operations, bedding within the Santiago Formation in the western portion of the site mostly
trends northwest-southeast with dips typically between 6 and 16 degrees to the southwest. In
the central portion of the site, the bedding becomes somewhat variable with most bedding
striking northwest-southeast with dips typically 2 to 18 degrees to the southwest and northeast.
However, some of the bedding in this area trends northeast-southwest with dips of 4 to 12
degrees to the southeast. In the northeastern portion of the site, geologic mapping during
grading encountered an anticline with an axis generally in a north-south direction. Bedding on
the west side of the anticline generally trended northwest-southeast dipping 5 to 15 degrees to
the southwest while bedding on the east side of the anticline largely trended northeast-
southwest dipping 5 to 15 degrees to the southeast. Locally, cross bedding was observed with
dips steeper than 20 to 25 degrees.
Geologic mapping of the terrace deposits indicated that the deposits were massive to
indistinctly bedded. Where bedding was observed, it generally trended east-west to northeast-
southwest dipping 2 to 14 degrees to the north-northwest.
Jointing on-site was observed to be very variable, but predominantly trended subparallel to the
existing slopes. Jointing dips were found to be generally moderately to steeply dipping. Jointing
was mainly encountered in the upper portion of the bedrock becoming less pronounced with
depth.
Randomly oriented shears were encountered in the Santiago Formation claystone and siltstone
units. Numerous wide, diffuse zones of shearing, as well as more well-defined zones, were
encountered in the bedrock, and are thought to be the result of regional tectonic shearing of the
relatively stiff and unyielding siltstone and claystone.
3.4 Faulting and Seismicit
The southern California region has long been recognized as being seismically active. The
seismic activity results from a number of active faults that cross the region, all of which are
related to the San Andreas transform system, a broad zone of right lateral faults that extend
from Baja California to Cape Mendocino. The numerous faults in Southern California include
active, potentially active, and inactive faults. The definitions of fault activity terms used here
are based on those developed for the Alquist-Priolo Special Studies Zone Act of 1972 (Bryant
and Hart, 2007).
Project No. 133023-03 Page 15 June 28, 2016
I Active faults are those faults that have had surface displacement within Holocene time
(approximately the last 11,000 years) and/or have been included within an Aiquist-Priolo
Special Studies Zone. Faults are considered potentially active if they show evidence of surface
displacement since the beginning of Quaternary time (about two million years ago), but not
since Holocene time. Inactive faults are those that have not had surface movement since the
I beginning of Quaternary time.
The site is not within a currently established Alquist-Priolo Earthquake Fault Zone for fault
I rupture hazard (formerly Special Studies Zones for fault rupture hazard). Based on a review of
geologic literature, no active faults are known to occur beneath or in the general vicinity of the
project site. Accordingly, it appears that there is little probability of surface rupture due to
I faulting beneath the site. There are, however, several faults located in sufficiently close
proximity that movement associated with them could cause significant ground motion at the
site.
I Although active faulting is not present within the site, faults relative to the off-shore step-over
of the Rose Canyon-Newport-Inglewood fault zone to the west and uplift of the Cretaceous
I sedimentary units to the south and southeast are known to exist in general vicinity of the site.
Regional active faults that occur within the San Diego area includes the off-shore Rose
I Canyon-Newport Inglewood fault zone to the west, the Elsinore, San Jacinto, and San Andreas
faults to the east, and the Coronado Bank and San Diego Trough faults offshore to the
southwest. The local Rose Canyon fault zone trends north-northwest through San Diego Bay
I
and downtown San Diego, crosses offshore at La Jolla Cove and continues northward off the
coast of North San Diego County. The closest known active faults to the site are the Rose
Canyon fault zone located 3.7 miles (6.0 kilometers) to the west; the Coronado Bank fault zone
I
located 20 miles (32 kilometers) to the southwest, and the Elsinore fault zone located
approximately 21 miles(34 kilometers) to the northeast (LGC, 2014a).
3.4.1 On-Site Faultinji
Geologic mapping during the mass grading operations encountered five essentially
l
north-south trending faults/fault zones across the site. In general, the faults/fault zones
were approximately 800 to 1000 feet apart. With the exception of the eastern-most fault
zone, all of the other faults/fault zones were encountered in the Santiago Formation and
U
appeared to die out toward the south. Based on our geologic analysis during the mass
grading operations and review of the applicable geotechnical reports referenced in
Appendix A, it is our professional opinion that the faults encountered on the site are not
I active; and therefore are not a constraint to development. Each of the encountered
faults/fault zones is discussed below.
Fault Zone in Western PA-3: Three minor inactive faults were geologically mapped in
I the back-cut of the stability fill on the south side of Lots 135 through 145 of PA-3. The
faults generally trended in a northwest-southeast to north-south direction. This fault
zone consists of two main fault strands with the western fault downside to the west I while the eastern fault is downside to the east. The western fault generally trends
Project No. 133023-03 Page 16 June 28, 2016
I Ni 5°W to Ni 5°E dipping 80 to 88 degrees to the northeast while the eastern strand
trends N5°W to N30°W dipping 50 to 60 degrees to the northeast. The third mapped
fault is steeply dipping and appears to die out to the north and south. A couple of
marker beds are offset and minor drag folding on the beds indicates the relative
movement is right-lateral.
Fault Zone in Western PA-5 and PA-6: The next fault zone to the east consists of one
main fault and three shorter faults geologically mapped in the stability fill back-cut in
the vicinity of Lots 52 through 57 of PA-5 and Lots 170 through 177 of PA-6. All of the
faults encountered generally trended N20°W to N35°W dipping 70 to 80 degrees to the
southwest and appeared to die out to the south. The main fault had an offset of
approximately 3 feet while the other faults had minor offsets of 6-inches or less.
Fault Zone in Eastern PA-5 and PA-6: The central fault zone was encountered along the
west side of Lots 212 through 218 of PA-6, the lots to the north in PA-6 and northward
through Lots 45 and 46 of PA-S. This fault zone consisted of three minor faults with
two of them being in-echelon. The in-echelon faults generally trended N5°W to
N15°W; however, the northern strand dipped 50 to 60 degrees to the northeast while
the southern fault dipped 75 to 85 degrees to the southwest. The sense of movement of
these faults was down to the west.
Fault Zone in PA-9 and PA-10: This fault zone was encountered running in a north
south direction through the middle of PA-9 and PA-10. Two subparallel faults were
geologically mapped in the southern and middle portions of the zone while at the north
end the two faults appeared to die out and become a series of possible step-over faults.
The two main faults generally trended NYE to N16°E dipping 60 to 85 degrees to the
west. The sense of movement of the western fault was down to the east while the
eastern fault was down to the west. The possible step-over faults trended NS°W to
N35°W dipping 55 to 70 degrees to the southwest and all were down to the west. A
short discontinuous fault was also mapped to the east with the same general trend and
dip but was down to the east.
Fault Zone in PA-i3: The eastern fault zone was encountered during the grading of PA-
12 and PA-13 in the southeast portion of Robertson Ranch by GeoSoils in 2008
(GeoSoils, 2008). The fault was exposed within the western portion of the sheet-graded
pad and found to only offset Pleistocene-aged terrace deposits. The fault was observed
to be sinuous, generally trended N30°E to N50°E, and was moderately dipping (45 to
55 degrees) mainly to the west. The fault was found to die out in the cut slope along the
northeast side of PA-13 and could not be traced through the southern portion of the
sheet-graded pad of PA-12. Based on geologic mapping and research by GeoSoils, it
was concluded by them that the fault was pre-Holocene in age and therefore not an
active fault (GeoSoils, 2008).
The approximate 30-foot wide fault zone with multiple fault splays across the zone,
previously mapped at the southeast corner of PA-6 during the preliminary geotechnical
investigation (LGC, 2014a), was very difficult to map both towards the north and south
Project No. 133023-03 Page 17 June 28, 2016
II during the mass grading operations. Based on the trend of the zone and location relative
to the fault zones mapped to the northwest and northeast, this fault zone is likely a step
over feature from one zone to the other.
3.5 Ground Water
Groundwater was encountered in the alluvium during some of the previous geotechnical
investigations at an approximate elevation of 45 feet msl. However, during the mass grading
operations only perched ground water was encountered in the alluvial soils within the main
drainage on the west side of the site and Planning Area PA-2 and in the drainage southeast of
Planning Area PA-6. With the exception of Planning Area PA-2 and the west end of Robertson
Road at Tamarack Avenue, all of the alluvial soils were completely removed to competent
formational material during the mass grading operations and subdrains installed in the canyon
bottoms. Consequently, groundwater conditions should not be a constraint to development.
However, since saturated alluvium and a shallow ground water condition is present within
Planning Area PA-2, the current groundwater condition should be evaluated as part of future
site design and construction of PA-2.
It should also be noted that no groundwater or seepage conditions were observed during the
mass grading operations within the single-family residential planning areas. However,
unanticipated seepage conditions may occur after the completion of grading and establishment
of site irrigation and landscaping. If these conditions should occur, steps to mitigate the seepage
should be made on a case-by-case basis.
Based on the site-specific as-graded geotechnical conditions and our geotechnical analysis
during site grading, LGC analyzed potential ground water conditions that may have resulted in
ground water seepage and appropriate recommendations, if necessary, have been made.

4.0 CONCLUSIONS
4.1 General
The mass-grading of Robertson Ranch Planning Areas PA-i through PA-3, PA-5, PA-6, PA-
9, PA-b, PA-13, and PA-23A through PA-23C located within the City of Carlsbad,
California was performed in general accordance with the project geotechnical report (LGC,
2014a), geotechnical recommendations made during the course of grading, and the City of
Carlsbad grading requirements. It is our professional opinion that the subject site is suitable
for the intended use provided the recommendations of the applicable referenced geotechnical
reports (LGC, 2014 through 2016j) or those provided at the completion of the future fine
grading are incorporated into the design and construction; and that proper landscaping,
irrigation, and maintenance programs are implemented. The following is a summary of our
conclusions concerning the mass-grading of Planning Areas PA-i through PA-3, PA-5, PA-
6, PA-9, PA- b, PA-13, and PA-23A through PA-23C.
4.2 Summary of Conclusions
I . Mass-grading of Robertson Ranch Planning Areas PA-1 through PA-3, PA-5, PA-6, PA-9,
PA- 10, PA- 13, and PA-23A through PA-23C is essentially complete.
Geotechnical conditions encountered during the mass-grading operation were generally
I as anticipated; with the exception of saturated alluvium in the western portion of the site
(see Section 2.2 of this report) and deeper than anticipated alluvial removals in the south-
central portion (see Section 3.2[4]).
I . The geologic units encountered during the mass-grading of the site consisted of
undocumented fill soils, topsoil, colluvium, alluvium, terrace deposits, and the Santiago
- Formation.
Unsuitable undocumented fill soils, desiccated older fill soils, topsoil, colluvium, alluvium,
and weathered terrace deposits and formational material were removed to competent
formational material within the limits of grading.
Landslides or surficial slope failures were not encountered during the grading operations.
No evidence of active faulting was encountered during the site mass-grading operations.
However, a number of minor faults and fault zones were encountered across the site.
Based on our geologic analysis, it is our professional opinion that the faults encountered
on the site are not active; and therefore, are not a constraint to development.
Minor perched ground water seepage conditions were encountered during the remedial
grading operations within the north-south trending canyon beneath Gage Drive between
PA-6 and PA- 10; but is not considered a constraint to development.
Placement of a 1- to 2-foot thick rock layer and/or a Mirafi 600x stabilization fabric was
installed in areas of PA-2 and the northwest portion of Robertson Road having a shallow
ground water condition and saturated alluvium.
Project No. 133023-03 Page 19 June 28, 2016
I
H
Since saturated alluvium and a shallow ground water condition are present within
Planning Area PA-2, the current groundwater condition should be evaluated as part of the
future site design and construction of PA-2.
Stability fills were constructed to improve the gross stability of the cut slopes exposing
fractured and blocky formational material and/or adverse geologic conditions on the site.
The stability fill keys were excavated in accordance with the project geotechnical
recommendations.
Subdrains were placed in the canyon bottoms and along the heel of the stability fill keys.
The subdrains were outletted into suitable storm drain facilities or near the toe-of-slope
of the stability fill slopes.
The cut portion of the cut/fill transition conditions present within the limits of Lots 29
through 32, 48, and 54 of PA-5; Lots 63, 68, 69, 71, 72, 77, 82, 88, 100, 112, 124, 133,
and 135 through 145 of PA-3; Lots 164, 165, 169 through 171, 189, 198 through 207, and
226 through 244 of PA-6; Lots 252, 253, 266 through 269, 275, 277 through 279, 287,
294, and 295 of PA-9; and Lots 300, 301, 305 through 307, 309 through 312, 317, 318,
and 323 of PA-10 were overexcavated a minimum of 5 feet beneath the finish grade
surface and to a distance of at least 10 feet outside the planned building limits.
Overexcavation of Lots 64 through 67, 70, 73 through 76, 83 through 87, 92 through 99,
105 through 111, 115 through 123, and 127 through 132 of PA-3; Lots 180 through 182
of PA-6; Lots 254 through 264, 270 through 274, 280 through 286, 292, 293 of PA-9; and
Lots 319 through 322 of PA-10 was performed in order to mitigate potential adverse
conditions due to expansive soils. The entire portion of the cut lots were overexcavated a
minimum of 5 feet below finish pad grade and replaced with compacted fill having a
• lower expansion potential.
Overexcavation of some of the cut lots was performed in order to mitigate the potential
I adverse condition of well-cemented sandstone beds (or concretion layers) and very dense or
hard Santiago Formation at or near finish grade which could create difficulties during future
excavations on the lots. Lots overexcavated due to well-cemented sandstone or dense
Santiago Formation included Lots 39 through 47 and 60 of PA-5; and Lots 158 through
163, 183, 184, 212, and 213 of PA-6.

. Toxaphene impacted soil present on the site was completely removed and buried within
the street right-of-ways of the site at depths greater than 12 feet below the finish surface
of the street or 2 feet below the deepest utility if the utility line was greater than 10 feet
I
in depth. The burial areas included a portion of West Ranch Street, Robertson Road,
Wellspring Street, and Nelson Court. Subsequent to the grading of the site in the areas of
the previously impacted soil and burial areas, 15 random post-grading soil samples were
I any
obtained and tested for toxaphene. The test results indicated the samples did not detect
toxaphene
During the mass-grading operations, remedial grading was performed so that the fill
differential beneath the proposed building pads was less than a 3:1 (maximum fill thickness
I to the minimum fill thickness).
Fill soils were derived from on-site soils. Where tested, the fill soils within the site were
I compacted at least a 90 or 93 percent relative compaction (based on ASTM Test Method
D1557) and near-optimum moisture content in accordance with the recommendations of
Project No. 133023-03 Page 20 June 28, 2016
1
the project geotechnical report (LGC, 2014a) and the requirements of the City of
Carlsbad. Fill soils less than 40 feet below the design finish grades were compacted to a
minimum 90 percent relative compaction while fill soils greater than 40 feet below the
design finish grades were compacted to a minimum 93 percent relative compaction. A
summary of the results of the field density tests is presented in Appendix C.
To mitigate post-construction settlement, deep fills (i.e. areas were the fill soils are
generally deeper than approximately 40 feet below the finish grade elevations of the
sheet-graded pads) were placed at a minimum relative compaction of 93 percent relative
compaction. Deep fill areas are present on Lots 192 through 194 and Gage Drive between
PA-6 and PA-10.
Due to the dense nature of the on-site soils, it is our professional opinion that the
liquefaction hazard at the site is considered low.
Representative testing of the finish grade soils on the building pads of the subject lots
indicated that: 1) Lots 25 through 59 of PA-5; Lots 61 through 67 of PA-3; and lots 172
through 188, 206 through 213, and 226 through 251 of PA-6 have a very low expansion
potential; 2) Lots 71 through 91 of PA-3; Lots 96 through 104, 106 through 110, 127
through 130, and 135 through 145 of PA-3; and Lots 158 through 171, 189 through 199,
and 214 through 225 of PA-6 have a low expansion potential; 3) Lots 13 through 23 of
PA-13; Lot 60 of PA-5; Lots 68, 69, 70, 92 through 95, 105, 111 through 126, 131
through 134, and 146 through 149 of PA-3; Lots 200 through 205 of PA-6; Lots 252
through 299 of PA-9; and Lots 300 through 326 of PA-10 have a medium expansion
potential; and 4) Lots 1 through 12 and 24 of PA-13 have a high expansion potential. The
test results are presented in Appendix B.
The potential for soluble sulfate attack on concrete in contact with the finish grade soils
of the subject lots is considered negligible to severe based on ACI Criteria (ACT 318R-08
Table 4.3.1). The soluble sulfate content test results are included in Appendix B.
Laboratory testing of representative soil samples indicated that the near surface soils are
corrosive to severely corrosive to buried metals. The laboratory test results are presented
in Appendix B.
It is our professional opinion that the slopes of the development are considered to be
grossly and surficially stable, as constructed, under normal irrigation/precipitation
patterns, provided the recommendations in the project geotechnical reports are
incorporated into the post-grading, construction, and post-construction phases of site
development.
Based on the settlement monument readings to date of the two monuments in Planning
Area PA-6 and in Gage Drive between Planning Areas PA-6 and PA-10 (i.e. Settlement
Monuments #6 and #7), settlement of the fills has been minimal. As a result, it is our
professional opinion that the primary and secondary consolidation of deep fills is within
acceptable limits.
The installation of the animal crossing was performed in general accordance with the
project geotechnical recommendations (LGC, 2015e) and pipe manufacture's
specifications (Sheets 45 through 51 of the Robertson Ranch Grading Plans
(O'Day, 2015).
Project No. 133023-03 Page 21 June 28, 2016
5.0 RECOMMENDATIONS
I 5.1 Earthwork
I
We anticipate that future earthwork at the site will consist of site preparation, fine-grading,
utility trench excavation and backfill, retaining wall backfill, and street/driveway and parking
area pavement section preparation and compaction. We recommend that the earthwork on
I
site be performed in accordance with the geotechnical recommendations presented in the
project preliminary geotechnical report (LGC, 2014a), recommendations provided after the
completion of the fine-grading operations, and the City of Carlsbad grading requirements.
5.2 Site Preparation
During future grading, the areas to receive structural fill or engineered structures should be
cleared of surface obstructions, potentially compressible material (such as desiccated fill
soils or weathered formational material), and stripped of vegetation. Vegetation and debris
should be removed and properly disposed of off-site. Holes resulting from removal of buried
obstructions that extend below finish site grades should be replaced with suitable compacted
fill material. Areas to receive fill and/or other surface improvements should be scarified to a
minimum depth of 12 inches, brought to optimum moisture condition, and recompacted to at
least 90 percent relative compaction (based on ASTM Test Method D1557).
If the length of time between the completion of grading and the construction of the
development is longer than six months, we recommend that the building pads be evaluated
by the geotechnical consultant and, if needed, the finish grade soils on the building pads
should be scarified a minimum of 12 inches, moisture-conditioned to optimum moisture-
content and recompacted to a minimum 90 percent relative compaction (based on ASTM
Test Method D1557).
5.3 PA-2 Future Work
A site-specific geotechnical evaluation should be performed once site development plans are
available. Since saturated alluvium and a shallow ground water condition are present within
Planning Area PA-2, the current groundwater condition should be evaluated as part of the
future site design and construction.
5.4 Excavations
Excavations of the on-site materials may generally be accomplished with conventional heavy-
duty earthwork equipment. It is not anticipated that blasting will be required or that significant
quantities of oversized rock (i.e. rock with maximum dimensions greater than 8 inches) will be
generated during future grading. However, localized cemented zones within the cut areas may
Project No. 133023-03 Page 22 June 28, 2016
I be encountered on the site that may require heavy ripping and/or removal. If oversized rock is
encountered, it should be placed in accordance with the project geotechnical recommendations
I (LGC, 2014a), hauled offsite, or placed in non-structural or landscape areas.
Temporary excavations maybe cut vertically up to five feet. Excavations over five feet should
I be slot-cut, shored, or cut to a 1:1 (horizontal to vertical) slope gradient. Surface water should
be diverted away from the exposed cut, and not be allowed to pond on top of the excavations.
Temporary cuts should not be left open for extended periods. Planned temporary conditions
I should be reviewed by the geotechnical consultant in order to reduce the potential for sidewall
failure. The geotechnical consultant may provide recommendations for controlling the length of
sidewall exposed.
5.5 Fill Placement and Compaction
I The on-site soils are generally suitable for use as compacted fill provided they are free of
organic material, debris, and rock fragments larger than 8 inches in maximum dimension. We
I
do not recommend that high or very high expansive soils be utilized as fill for the building pads
or as retaining wall backfill.
Fill soils should be brought to 2-percent over the optimum moisture content and compacted in
uniform lifts to at least 90 percent relative compaction based on the laboratory maximum dry
density (ASTM Test Method D1557). The optimum lift thickness required to produce a
uniformly compacted fill will depend on the type and size of compaction equipment used. In
general, fill should be placed in lifts not exceeding 8 inches in compacted thickness. Placement
and compaction of fill should be performed in general accordance with current City of Carlsbad
grading ordinances, sound construction practices, and the project geotechnical
recommendations.
If import soils are to be used as fill, the soils should be: 1) essentially free from organic matter
and other deleterious substances; 2) contain no materials over 6 inches in maximum dimension;
3) have a very low to low expansion potential (i.e. an Expansion Index ranging from 0 to 50);
and 4) have a negligible sulfate content. Representative samples of the desired import source
should be given to the Geotechnical Consultant at least 48 hours (2 working days) before
importing grading begins so that its suitability can be determined and appropriate tests
performed.
5.6 Foundation Recommendations
- The preliminary foundation design recommendations applicable to the construction of the
I
residential structures on Planning Areas PA-3, PA-5, PA-6, PA-9, PA-b, and PA-13 of
Robertson Ranch were previously provided under separate cover (LGC, 2015a through 2016d).
The previous recommendations remain appropriate for the design of the proposed structures on
I
the applicable subject lots.
Project No. 133023-03 Page 23 June 28, 2016
5.7 Subdrain Outlet Maintenance
The approximate location of the subdrains and subdrain outlets constructed during the mass-
grading operations are identified on the As-Graded Geotechnical Map (Plates 1A
I through IF). All subdrain outlets should be periodically cleared of soil cover or other
potential blockage that may have occurred since initial subdrain construction. If retaining
walls are proposed along the toe-of-slope in the location of the stability fills/subdrain outlet
locations, the existing subdrains should be tied into the retaining wall back-drain system
and/or placed into an appropriate storm drain facility.
5.8 Control of Surface Water and Drainae
I Surface drainage should be carefully taken into consideration during fine-grading, landscaping,
and building construction. Positive drainage of surface water away from structures is very
important. No water should be allowed to pond adjacent to buildings or the top of slopes.
Positive drainage may be accomplished by providing drainage away from buildings at a
gradient of at least 2 percent for a distance of at least 5 feet, and further maintained by a swale
of drainage path at a gradient of at least 1 percent. Where limited by 5-foot side yards, drainage
should be directed away from foundations for a minimum of 3 feet and into a collective swale
or pipe system. Where necessary, drainage paths may be shortened by use of area drains and
collector pipes. Eave gutters also help reduce water infiltration into the subgrade soils if the
I
downspouts are properly connected to appropriate outlets.
The impact of heavy irrigation or inadequate runoff gradient can create perched water
I
conditions, resulting in seepage or shallow groundwater conditions where previously none
existed. Maintaining adequate surface drainage and controlled irrigation will significantly
reduce the potential for nuisance-type moisture problems. To reduce differential earth
I
movements (such as heaving and shrinkage due to the change in moisture content of foundation
soils, which may cause distress to a structure or improvement), the moisture content of the soils
surrounding the structure should be kept as relatively constant as possible.
I All area drain inlets should be maintained and kept clear of debris in order to function properly.
Rerouting of site drainage patterns and/or installation of area drains should be performed, if
necessary. A qualified civil engineer or a landscape architect should be consulted prior to
I rerouting of drainage.

Laboratory Testing Procedures and Test Results (continued)
Corrosion Suite Tests: Soluble sulfate content, soluble chloride content, minimum resistivity and pH
tests of representative soil samples were performed and presented herein. The soluble sulfate content
was tested in accordance with Caltrans Test Method (CTM) 417 while the chloride content was tested
in accordance with CTM 422. Minimum resistivity and pH tests were performed in general accordance
with CTM 643. The electrical resistivity of a soil is a measure of its resistance to the flow of electrical
current. As a results of soil's resistivity decreases corrosivity increases. The results are presented in the
