LG-04397 and LG-04398 dated September 2, 2004, we have provided compaction testing and observation services during construction of the site improvements at the subject project. We performed our services during the period of June 4, 2004 through June 3, 2008. The scope of our services included the following: Performing in-place density tests on an "on-call" basis during utility trench backfill operations including storm drain, sewer main, sewer lateral, water main, water lateral, and joint trench backfill; Performing in-place density tests during the preparation of curb and gutter, sidewalk, minor pad re-grading, retaining wall repair, roadway subgrade and the placement of aggregate base and asphalt concrete pavement; Providing geotechnical consultation services during improvement operations; Performing laboratory tests to aid in evaluating the compaction characteristics of various soil conditions encountered and/or used for fill, including asphalt concrete and base materials; and Preparing this final report of improvements. To aid in preparing this report, we have reviewed the following report and plans associated with the project improvements: Final Report of Testing and Observation Services Performed During Site Grading, Villages of La Costa - The Greens, Neighborhood 1.11, 1.13, 1.14, and Alicante Road Stations 10+00 through 31+00, Carlsbad, California, prepared by Geocon Incorporated, dated July 27, 2004. (Project No. 06403-52-09). Improvement Plans for. La Costa Greens - Neighborhoods 1. 11, 1. 13, 1.14, prepared by Hunsaker and Associates (Drawing No. 406-3), City of Carlsbad approval dated May 6, 2004. 6960 Flanders Drive • San Diego, California 92121-2974 • Telephone (858) 558-6900 U Fox (858) 558-6159 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 density gauge in accordance with ASTM Test Procedures D 2922 and D 2950 for soil and asphalt concrete, respectively. We performed laboratory tests on soil and base samples in accordance with ASTM D 1557, Maximum Dry Density and Optimum Moisture Content; D 422, Particle Size/Sieve Analysis; D 2419, Sand Equivalent Value. In addition, we performed laboratory tests on asphalt concrete samples in accordance with ASTM D 2726, Hveem Density; D 2041, Theoretical Maximum Density; D 1560, Stability; C 136, Sieve Analysis; and D 6307, Asphalt Content. The reults of the in-place density tests are summarized in Table I and laboratory test results are summarized in Tables II through VI. We performed laboratory tests on base materials and asphalt concrete to check conformance with Standard Specifications for Public Works Construction (Greenbook). The results of the laboratory tests indicate the samples are in general conformance with the exception of test results in Tables 1V and V in bold type. These results have been reported to the John Laing Homes on-site superintendent and to the City of Carlsbad representative. In general, the results of the in-place density tests indicate that utility trench backfill, minor pad re-grading, retaining wall repair, and sidewalk subgrade materials 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-place density test results indicate that the curb and gutter, roadway subgrade and aggregate base materials possess a dry density of at least 95 percent of the laboratory maximum dry density near to slightly above optimum moisture content at the locations tested. In-place density test results indicate that the asphalt concrete is compacted to at least 95 percent of the Hvem density at the locations tested. Based on observations and test results, it is the opinion of Geocon Incorporated that the construction of site improvements, which is the subject of this report, has been performed in substantial conformance with the recommendations of the project geotechnical report. Any additional grading and/or improvement installation performed at the site should be accomplished in conjunction with our observation and testing services. Grading plans for any future grading should be reviewed by Geocon Incorporated prior to finalizing. Trench and wall backfill and sidewalk subgrade should be compacted to a dry density of at least 90 percent of the laboratory maximum dry density near to slightly above optimum moisture content. 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 Project No. 06403-52-16 A&B - 2 - June 27, 2008 a • 1 from pavements, curb and 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.

TABLE I EXPLANATION OF CODED TERMS - TEST SUFFIX A, B, C,... : Retest of previous density test failure, following moisture conditioning and/or recompaction.

Corresponds to curve numbers listed in the summary of laboratory maximum dry density and optimum moisture content test results table for selected fill soil samples encountered during testing and observation. - ROCK CORRECTION For density tests with rock percentage greater than zero, laboratory maximum dry density and optimum moisture content were adjusted for rock content. For tests with rock content equal to zero, laboratory maximum dry density and optimum moisture content values are unadjusted. - TYPE OF TEST SC: Sand Cone Test (ASTM D1556) NU: Nuclear Density Test (ASTM D2922) OT: Other - ELEVATION/DEPTH Test elevations/depths have been rounded to the nearest whole foot. - LOCATION DESCRIPTION (IF): Indicates in-place tests. Where (IP) appears in the location description, the compaction procedures were not observed by a representative of Geocon. Tests were taken at the surface or in test pits after placement of the fill. The results of these tests are indicative of the relative compaction at the location of the test only and may not-be extrapolated to adjacent areas. Geocon has no opinion regarding the relative compaction of fill in adjacent 'areas. Project No. 06403-52-16 . .
