Attention: Mr. Beau Brand
Subject: PRECISE GRADING PLAN REVIEW AND
UPDATED GEOTECHNICAL REPORT
Palomar Forum Project, Parcel A, 5980 Eagle Drive
City of Carlsbad, California
References: See Appendix A
Dear Mr. Brand:
Presented herein is Alta California Geotechnical, Inc.’s (Alta) precise grading plan review and
updated geotechnical report for the Palomar Forum Project, Parcel A, located at 5980 Eagle
Drive, in the City of Carlsbad, California. This review is based on the Precise Grading Plans
prepared by Excel Engineering and the referenced report.
Alta had previously prepared the referenced geotechnical investigation report for the subject
site. Our review of the previous data, with respect to the precise grading plans, indicates that
the proposed project is feasible, from a geotechnical perspective, provided that the
recommendations presented in this report and in the referenced report are incorporated into
the grading and improvement plans and implemented during site development.

1.0 REVIEW OF PRECISE GRADING PLANS
Alta has reviewed the precise grading plans (dated March 25, 2021) for the subject site,
provided by Excel Engineering, with respect to the geotechnical recommendations
presented in the referenced report. The precise grading plans were found to be in
general conformance with the geotechnical recommendations for the project.
2.0 UPDATED GEOTECHNICAL MAP AND CROSS SECTIONS
Alta has prepared an updated geotechnical map and cross sections (Plates 1 through 3),
utilizing the current precise grading plans provided by Excel Engineering as a base
(Sheets 2, 6 and 7 of 10). Included on the updated geotechnical map and cross sections
are geologic units and the approximate location of the test pits from the referenced
report. The geotechnical data presented on the attached plans is based on the
conclusions and recommendations presented in the referenced report.
3.0 UPDATED PROPOSED DEVELOPMENT
The general site location of the project is presented on Figure 1. Based on our review of
the precise grading plans, the site will be developed into a parking lot with four (4) bio‐
retention basins and associated improvements, including curb and gutter and hardscape
areas. Alta anticipates that conventional cut‐and‐fill grading techniques will be used to
develop the site for the support of wood‐frame and stucco construction with shallow
foundations and reinforced concrete slabs‐on‐grade, and associated improvements.
Significant height slopes are not proposed for the project.
4.0 PREVIOUS GRADING
The initial geotechnical investigation of the site was conducted by Vinje & Middleton
Engineering, Inc. in 1998 (Vinje, 1998) as part of the overall Palomar Forum
Development. An updated report and grading plan review were prepared in 2002
(Vinje, 2002). A grading report was prepared upon completion of grading operations in
2005 (Vinje, 2005). The subject site was designated as Lots 6 and 7 in the grading
report.

5.0 UPDATED STRATIGRAPHY
Based on Alta’s review of geologic literature and our subsurface investigation, the
project site is underlain by engineered artificial fill overlying the Santiago Formation
(Kennedy, 2007). Based on review of the referenced grading report (Vinje, 2005), all
alluvium/colluvium that was previous onsite was removed to expose Santiago
Formation and recompacted. The geologic unit encountered during our investigation is
briefly described below.
5.1 Artificial Fill‐Engineered (map symbol afe)
The engineered fill onsite primarily consists of orange tan to orange brown,
grayish brown, and dark brown, sandy clay and clayey sand in a dry to slightly
moist, dense/stiff to very dense/stiff condition. The unit was logged to a
maximum depth of 13 feet below the ground surface.
6.0 INFILTRATION FEASIBILITY
Infiltration testing was conducted at the site as part of our previous investigation, and
the methodology is discussed in Section 3.2 of Reference 1. The resulting infiltration
rate for PT‐1 through PT‐3 was calculated to be 0.36 inches per hour (factor of safety
not applied) at approximately 6‐feet below the existing ground surface. A factor of
safety of 2.0 should be utilized on the results. Forms I‐8 and I‐9 from the Carlsbad BMP
Design Manual are presented in Appendix B.
Based on a review of the referenced reports the site is underlain by the Santiago
Formation which is overlain by engineered artificial fill across the entire site. A review
of the NRCS Survey maps indicates that the site is underlain by C and D soils.
6.1 Discussion on BMP Design
Given the characteristics of the underlying soil, full infiltration systems are not
feasible in our opinion. In order to achieve enough capacity, any full infiltration
system would need to incorporate a deep system, which will be problematic in
the underlying soils due to low infiltration rates and presence of bedrock.
Project Number 1‐0346 Page 5
May 6, 2021
ALTA CALIFORNIA GEOTECHNICAL, INC.
Additionally, given overlying layers of artificial fill onsite, partial/shallow
infiltration BMP’s will also be ineffective in our opinion.
6.2 Conclusions Regarding Infiltration
Based on testing, the geologic units onsite do not have infiltration rates high
enough to support infiltration‐type BMP’s and there is artificial fill and bedrock
onsite which are not suitable for infiltration. As such, based on the presence of
artificial fill and bedrock, and the tested infiltration rate below 0.5 in/hr, it is
Alta’s opinion that relying on full/partial infiltration‐type methodologies for the
BMP design is not suitable for this project. Alternate systems should be
considered for BMP design onsite.
7.0 UPDATED PAVEMENT DESIGN
Pavement sections for the proposed parking lot shall be designed based on laboratory
testing conducted on samples taken from the soil subgrade. Preliminarily, based on a
tested R‐Value of 24 from the referenced report, the pavement may be designed
utilizing the sections presented in Table 4‐1. These sections should be verified upon the
completion of grading, based on R‐Value testing.

AB‐Caltrans Class II Base
Prior to the placement of base material, the subgrade should be suitably moisture
conditioned, processed and compacted to a minimum 95 percent of the laboratory
maximum density (ASTM: D 1557) to at least twelve (12) inches below subgrade. After
subgrade compaction, the exposed grade should then be "proof"‐rolled with heavy
equipment to ensure the grade does not "pump" and is verified as non‐yielding.

Aggregate base material should be placed on the compacted subgrade and compacted
in‐place to a minimum 95 percent of the laboratory standard obtained per ASTM: D
1557.
8.0 LIMITATIONS
The conclusions and recommendations in this report are based on the information
generated during the previous investigation, review of the referenced report, and our
review of the updated preliminary grading plans. The materials immediately adjacent to
or beneath those observed may have different characteristics than those observed, and
no representations are made as to the quality or extent of material not observed.

The tests were conducted at the bottom of the test pits in an approximately 1-foot deep hand dug boring.
During the test, the hand-dug borings were filled with water and the level was measured every 30 minutes
until the readings stabilized. The data was then adjusted to provide an infiltration rate utilizing the Porchet
Method.
