Subject Summary of Field Observations and Compaction Test Results
This report presents a summary of our field observations during grading along with the results of
in-place density tests performed at the subject site as requested The project site is located at 2100
Costa, Del Mar Road at the La Costa Resort and Spa development in the City of , Carlsbad,
California. The grading observations and testing summarized herein were limited to the
- reconfigured golf course areas just west of the new adult pool complex and specifically along the
new emergency access roadway.
Compaction testing was performed from June 28, 2011 to July 28, 2011. Testing indicates that a -
minimum of 90- percent relative compaction was attained in the areas tested within the
emergency access Iroadway and adjacent slope areas.
-
In non-structural golf course areas beyond
the emergency access roadway the fill soil was -placed and spread using a track dozer. The
adequacy of the compaction of non-structural fill areas was based 'upon the minimums of either
85 percent relative compaction or 85 percent saturation..
Field Tests In place moisture/density tests were performed using a nuclear density gauge in
accordance with ASTM Test Method D6938-08. A total of 62 field density tests were performed.
The approximate test locations are indicated on the attached plans The tests were conducted in
general accordance -with ASTM Test Method D 6938 (Nuclear Density Gauge).
Results of the field density tests and calculated relative compaction are -summarized ' on the
attached table (Table 1). The maximum dry density and optimum moisture content determined in
the laboratory have also been indicated. .. . -
October 3,201l Project No. 422-11047-1
SBPII-lO-075
Laboratory Tests: The moisture-density relationships for the soil were determined in the
laboratory in accordance with ASTM-D Test Method 1557-91.
In addition to compaction testing, Sladden Engineering observed the excavation of various key
ways adjacent to structural fill areas. The approximate key way locations, bottom elevations and
the dates observed are also indicated on the attached plans.
If there are any questions regarding this report or the testing summarized herein, please contact
