We performed our services during the period of July 28, 2005 through April 8, 2008. The scope of our services included the following: Performing testing and observation services during utility trench backfill operations including storm drain, sewer main, sewer lateral, water main, water lateral, reclaimed water main, irrigation, and joint trench. We also performed in-place density tests during the preparation of sidewalk, curb and gutter and roadway subgrade and the placement of aggregate base and asphalt concrete pavement. Preparing concrete cylinders "as requested" for compression testing. Providing geotechnicál consultation 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. Preparing this final report of improvements. To aid in preparing this repdrt, we have reviewed the following report and plans associated with the project improvements: 1. Final Report of Testing and Observation Services Performed During Site Grading, Villages of La Costa - The Greens, Neighborhood 1.06 and 1.07, Carlsbad, California, prepared by Geocon Incorporated, dated December 29, 2005 (Project No. 06403-52-19B)., 6960 Flanders Drive 0 San Diego, California 92121-2974 0 Telephone (858) 558-6900 • Fax (858) 558-6159 2. Improvement Plans and Utility Plans for: La Costa Greens - Neighborhood 1.07 Backbone, Drawing No. 427-6B, prepared by Hunsaker and Associates, City of Carlsbad approval dated June 7, 2005. Duringthe 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 2922-05 and D 2950-05 for soil and asphalt concrete, respectively. We performed laboratory tests on soil and base samples in accordance with ASTM D 1557-02, Maximum Dry Density and Optimum Moisture Content; D 422-03, Particle Size/Sieve Analysis; D 2419-02, Sand Equivalent Value. In addition, we performed laboratory tests on asphalt concrete samples in accordance with ASTM D 2726-05A, Hveem Density; D 2041-03a, Theoretical Maximum Density; D 1560-05, Stability; C 136-05, Sieve Analysis; D 6307-05, Asphalt Content; and Concrete Compression Testing C 39/C 9M-05. The results of the in-place density tests are summarized in Table I and laboratory test results are summarized in Tables II through VI. The comprssion test results for concrete cylinders are summarized in Appendix A. 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. These results have been reported to the Morrow Development 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 and driveway 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 Jndicate that the asphalt concrete is compacted to at least 95 percent of the'Hveem density at the locations tested. Prior to the' placement of the ½-inch asphalt concrete cap, localized areas of distressed pavement were removed and replaced on Geode Way, Quartz Way, and Mica Road. The contractor placed stabilization fabric at the base of the removal and the resulting excavation was replaced with base material compacted to 95 percent of the laboratory maximum dry density near to slightly above optimum moisture content. Addiiionally 3/4-inch asphalt concrete was placed to design grade and was capped with V2-inch asphalt concrete. 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. Project No. 06403-52-21 - 2 - April 28, 2008 Any additional grading and/or. mprovement. installation performed at the site should be accomplihed in conjunction with our observation and testing ser'ices. 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. S - 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 and gutters, and sidewalks to controlled drainage devices. Irrigatibn' of landscape areas adjacent to pavements shouldbe monitored to provide just enough water to support plant life. Should you have an questions regarding this report, or if we may be of further service, please contact the undersigned at your convenience.

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 (TIP) appears inthe location description, the compaction pro'cedures 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 opinión regarding the relative compaction of fill in adjacent areas.
