C-ro'4 .orJ FINAL REPORT OF TESTING AND OBSERVATION SERVICES PERFORMED DURING SITE IMPROVEMENTS VILLAGES OF LA COSTA - THE RIDGE NEIGHBORHOODS 2.3 AND 2.4 (NORTH) LOTS 49 THROUGH 103 CARLSBAD, CALIFORNIA PREPARED FOR SHEA HOMES SAN DIEGO, CALIFORNIA AUGUST 16, 2010 PROJECT NO. 07290-52-05 GEOCON INCORPORATED GEOTECHNICAL • ENVIRONMENTAL. M A T E R I A L S (107) Project No. 07290-52-05 August 16, 2010 Shea Homes 9990 Mesa Rim Road San Diego, California 92121 Attention: Mr. Greg Ponce Subject: VILLAGES OF LA COSTA - THE RIDGE NEIGHBORHOODS 2.3 AND 2.4 (NORTH), LOTS 49 THROUGH 103 FINAL REPORT OF TESTING AND OBSERVATION SERVICES PERFORMED DURING SITE IMPROVEMENTS Dear Mr. Ponce: In accordance with your request and our Proposal No. LG-05430 dated October 11, 2005 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 November 28, 2005 through August 3, 2010. The scope of our services included: Performing testing and observation services during pad-regrading. Performing in-place density tests on an "on-call" basis during utility trench backfill operations including storm drain, sewer main, sewer laterals, water main, water laterals, joint trench and wall backfill; Performing in-place density tests during the preparation of curb and gutter, sidewalk subgrade, and the placement of aggregate base and asphalt concrete pavement; Providing geotechn ical 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 reports and plans associated with the project improvements: 1. Final Report of Testing and Observation Services Performed During Site Grading, Villages of La Costa - The Ridge, Neighborhoods 2.3 and 2.4, Carlsbad, California, prepared by Geocon Incorporated, dated September 16, 2005 (Project No. 07290-52-01). 6960 Flanders Drive 0 San Diego, California 92121-2974 0 Telephone 858.558.6900 0 Fax 858.558.6159 Update Geotechnical Report,' Villages of La Costa - The Ridge, Neighborhoods 2.3 and 2.4 (North), Lots 49 through 103, Carlsbad, California, prepared by Geocon Incorporated, dated January 26, 2006 (Project No. 07290-52-05). Improvement Plans and Utility Plans for: La Costa Ridge - Neighborhoods 2.3 and 2.4 (North), prepared by Hunsaker and Associates (Drawing No. 420-5), City of Carlsbad approval dated August 23, 2005 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; and D 2419, Sand Equivalent Value. In addition, we performed laboratory tests on asphalt concrete samples in accordance with ASTM D 2726, Hveem Densiy; D 2041, Theoretical Maximum Density; D 1560, Stability; C 136, Sieve Analysis; and D 6307, Asphalt Content. The results of the in-place density tests are summarized in Table I and laboratory test results are summarized in Tables II through VI. We tested samples of crushed aggregate base 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 IV through VI in bold type. These results have been reported to the Shea Homes on-site superintendent and to the City of Carlsbad. In general, the results of the in-place density tests indicate utility trench backfill, sidewalk subgrade, and wall backfill 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 the asphalt concrete is compacted to a density of at least 95 percent of the Hveem density at the locations tested. The results of the in-place density tests are summarized in Table I and laboratory test results are summarized in Tables II through VII. We corrected the laboratory maximum dry density and optimum moisture content on fill soil being tested containing rocks larger than 3/4 inch Using methods suggested by AASHTO T224 and others. The values of maximum dry density and optimum moisture content presented on Table I reflect these corrections. Project No. 07290-52-05 -2- August 16, 2010 Based on observations and test results, it is the opinion of Geocon Incorporated that the constuction of site improvements, which is the subject of this report, has been performed in substantial conformance with the recommendations of the project geotechnical report. Additional grading and/or improvement installation performed at the site should be accomplished in conjunction with our observation and testing services. Grading plans for 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 commecing 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 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. Should you have any questions regarding this report, or if we may be of further service, please contact the undersigned at your convenience. Very truly yours, GEOCON INCORPORATED 2d&9 Michael C.

TABLE I EXPLANATION OF CODED TERMS - TEST SUFFIX A, B, C,. . . : Retest of previous density test failure, following moisture conditioning and/or recompaction. Fill in area of density test failure was removed and replaced with properly compacted fill soil. - PREFIX CODE DESIGNATION FOR TEST NUMBERS 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 D 1556) NU: Nuclear Density Test (ASTM D 6938) OT: Other - ELEVATION/DEPTH Test elevations/depths have been rounded to the nearest whole foot.
