SERVICES PERFORMED DURING SITE IMPROVEMENTS
HIGHLAND 5
2908 – 2924 HIGHLAND DRIVE
CARLSBAD, CALIFORNIA
Dear Mr. McDonnell:
In accordance with our proposal LG-22487 dated October 18, 2022, we provided geotechnical testing
and observation services during construction of site improvements for the Highland 5 project located
in the City of Carlsbad, California. We provided our services from February 16, 2023 through August 6,
2024. The scope of our services included:
Performing in-place density tests on an “on-call” basis during utility trench backfill operations including joint trench, storm drain, sewer lateral, sewer main, water lateral and water main.
Performing in-place density testing of subgrade soil for the curb/gutter and roadways and during the placement of aggregate base and asphalt concrete.
Providing geotechnical consultation services during improvement operations.
Performing laboratory tests to aid in evaluating the compaction characteristics of soil conditions encountered and/or used for fill, including base materials and asphalt concrete.
Preparing this final report of improvements.
To aid in preparing this report, we reviewed the referenced report and plans associated with the
project improvements.
1.Final Report of Testing and Observation Services Performed During Site Grading, Highland 5, Lots 1 through 5, 2908 – 2924 Highland Drive, Carlsbad, California, prepared by Geocon Incorporated, dated November 7, 2023 (Project No. G2861-11-03).
2.Grading Plans for: Highland Drive, 5 Lot Single Family Residence (2908 – 2924 Highland Drive), prepared by Pasco, Laret, Suiter & Associates, dated March 14, 2024 (PD2022-0043), (GR2021-0044).
Highland 5
Final Report of T&O During Site Improvements
Project No. G2861-11-03 - 2 - August 13, 2024
During the construction of site improvements, we observed compaction procedures and performed
in-place density tests to evaluate the dry density and moisture content of the fill materials. We
performed in-place density tests using a nuclear gauge in accordance with ASTM D 6938. Table I
presents the results of the in-place density tests. We performed laboratory tests on soil and aggregate
base samples in accordance with ASTM D 1557 (Maximum Dry Density and Optimum Moisture
Content). We performed laboratory tests on asphalt concrete samples in accordance with ASTM
D 2726 (Hveem Density), D 2041 (Theoretical Maximum Density), D 1560 (Stability), D 6307 (Asphalt
Content), and C 136 (Sieve Analysis). Tables II through IV present the results of the laboratory testing.
In general, the results of the in-place density tests indicate utility trench backfill possess a dry density
of at least 90 percent of the laboratory maximum dry density near to slightly above optimum moisture
content at the locations tested. In addition, in-place density tests taken for the curb/gutter subgrade,
roadway subgrade and base materials in vehicular areas possess a dry density of at least 95 percent of
the laboratory maximum dry density to near to slightly above optimum moisture content. In-place
density test results indicate that the asphalt concrete in the roadways possesses a density at least 95
percent of the laboratory maximum Hveem density.
Based on observations and test results, we opine the construction of site improvements, which is the
subject of this report, has been performed in substantial conformance with the recommendations of
the referenced project geotechnical report. Additional improvement installation associated with the
Highland 5 project should be performed in conjunction with our observation and testing services. This
office should be notified at least 48 hours prior to commencing additional grading or backfill
operations.
Adequate drainage provisions are imperative. Under no circumstances should water be allowed to
pond adjacent to improvements. Finish grades should be established so that drainage water is directed
away from pavements, curb/gutters and sidewalks to controlled drainage devices. Irrigation of
landscape areas adjacent to pavements should be monitored to provide just enough water to support
plant life.

SUMMARY OF FIELD DENSITY TEST RESULTS
>¾" ROCK - ROCK CORRECTION
The laboratory maximum dry density and optimum moisture content can be adjusted for in-place soil that possesses rock larger than
¾ inch. The curve no. is adjusted for the percentage of ¾ inch rock in accordance with ASTM D 4718 or Woodward Clyde guidelines.
TEST NO. - PREFIX
TEST NO. - RE.
Retest of previous density test failure following additional moisture conditioning or recompaction
Fill in area of density test was removed during construction operations
CURVE NO.
Corresponds to the curve numbers presented in the summary of the laboratory maximum dry density and optimum moisture
content test results. The field representative selected the curve no. based on the laboratory test results and field observations.
ELEVATION OR DEPTH
Corresponds to the elevation or the depth, in feet, of the in-place density/moisture content test. The value has been rounded to the
nearest whole foot.
