GEOCON INCORPORATED GEOTECHNICAL CONSULTANTS I Project No. 06105-12-07 March 25, 2003 I Real Estate Collateral Management Company I C,0 Morrow Development Incorporated 1903 Wright Place, Suite 108 Carlsbad, California 92008 I Attention: Mr. Tim O'Grady I Subject: RANCHO SANTA FE ROAD STATIONS 174+50 THROUGH 217+90 CARLSBAD, CALIFORNIA I FINAL REPORT OF TESTING AND OBSERVATION SERVICES PERFORMED DURING IMPROVEMENTS I Gentlemen: In accordance with your request and our proposal dated May 16, 2002, we have provided testing and I observation services during the installation of improvements within the subject roadway alignment. The scope of our services was limited to performing in-place density tests during utility trench backfilling operations for joint trenches, storm drain, sewer main, and water main. Our services were I performed during the period of May 20, 2002 through March 8, 2003. It should be noted that our scope of services was limited to underground utilities only and did not include surface paving. In addition, testing and observation services were also provided during grading operations for the construction of the subject roadway. A discussion of grading operations and the results of our testing and observation services were presented in our report titled, Final Report of Testing and Observation Services Performed During Grading, Rancho Santa Fe Road, Stations '174+50 through 217+90, Carlsbad, California, dated March 11, 2003 (Project No. 06105-12-07). The project improvement plans were prepared by Hunsaker & Associates and are entitled Improvement Plans for Rancho Santa Fe Road, Sheet Nos. 1 through 30, dated June 3, 2002. In-place density tests were performed using a nuclear gauge in accordance with ASTM Test Procedure D 2922-96. Laboratory compaction tests were performed on representative soil samples in accordance with ASTM Test Procedure D 1557-00. The results of the field density tests are summarized in Table I, and the results of the laboratory tests are summarized in Table II. 6960 Flanders Drive • San Diego, California 92121-2974 • Telephone (858) 558-6900 U Fax (858) 558-6159 I I I I [1 I I 11 Results of the in-place density tests jndicate that the utility trench backfill materials possess a dry density of at least 90 percent of the laboratory maximum dry density near to slightly above the optimum moisture contents at the locations tested.

Corresponds to curve numbers listed in Table II, representing the laboratory maximum thy density/optimum moisture content data for selected fill soil samples encountered during testing and observations. - 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 thy density and optimum moisture content values are then unadjusted values. - ELEVATION/DEPTH Test elevations/depths have been rounded to the nearest whole foot. - TYPE OF TEST SC: Sand Cone Test NU: Nuclear Density Test - DC: Drive Cylinder Test f:\wpjob\tgeoconoffice\yp-word\document\DNSLGEND.doc (6/96) TABLE II SUMMARY OF LABORATORY MAXIMUM DRY DENSITY AND OPTIMUM MOISTURE CONTENT TEST RESULTS ASTM 0 1557-00 Sample Maximum Optimum No. Description Dry Density Moisture Content S (pci) (% dry weight) 1 Orange to olive-brown, mottled, very Clayey 119.6 13.7 SAND 2 Brown, Clayey GRAVEL 123.6 11.4 3 Olive gray, Sandy CLAY 119.0 12.7 4 Reddish brown, Clayey SAND 125.2 11.3 5 Dark brown, Sandy CLAY 116.4 16.1 6 Brown, Clayey GRAVEL 125.4 11.6 7 Dark brown, Silty SAND 122.8 11.0 8 Reddish-brown, Gravelly, fine to coarse SAND 123.0 11.9 with trace silt 9 Reddish-gray, Sandy, fine to coarse GRAVEL 126.9 10.7 with trace clay 10 Yellowish-brown, Clayey, fine to coarse SAND 126.4 10.1 11 Light yellowish-brown, Silty CLAY with trace 108.0 18.3 sand 12 Dark Olive-brown, Sandy, fine to coarse 143.0 6.9 GRAVEL with trace sand 13 Light yellowish-brown, fine Sandy CLAY with 122.8 11.2 trace gravel 14 Dark Reddish-brown, fine to coarse Sandy 140.0 6.1 GRAVEL with trace clay 15 Brown, fine to medium Sandy CLAY with trace 122.9 11.0 gravel 16 Gray-brown, Silty, fine to coarse SAND with 130.9 9.9 trace gravel 17 Light Olive-gray, Silty CLAY with sand and 117.6 13.4 gravel 18 Dark Grayish-brown, fine to medium SAND with 123.0 11.8 trace clay and gravel 19 Dark brown, fine to medium SAND with silt and 124.8 10.2 trace gravel 20 Dark brown, fine to coarse, Sandy GRAVEL with 141.9 5.8 trace of silt 21 Dark brown, fine to coarse, Sandy GRAVEL with 138.0 7.0 trace of silt I Project No. 06105-12-07 March 25, 2003 I I I I I I I [1 I I H I I I I I TABLE II (Continued) SUMMARY OF LABORATORY MAXIMUM DRY DENSITY AND OPTIMUM MOISTURE CONTENT TEST RESULTS ASTM D 1557-00 Maximum Optimum Sample Description Dry Density Moisture Content No. (PC') (% dry weight) 22 Olive gray, Clayey fine SAND 125.8 10.3 23 Brown, fine to coarse, Sandy CLAY with some 120.1 12.3 gravel 24 Grayish brown, fine to coarse, Sandy GRAVEL 121.1 12.0 with trace silt 25 Olive brown, fine to coarse, Sandy GRAVEL 140.6 6.6 with trace silt 26 Olive brown, fine to medium, Sandy GRAVEL 138.5 6.9 with silt 27 Dark gray, fine to coarse, angular SAND with 135.8 7.5 trace silt 28 Light brown-gray, fine to coarse, Silty SAND 129.0 10.9 with trace gravel and clay 29 Light brown-gray, fine to coarse, Silty SAND 130.1 10.9 with trace gravel and clay 30 Reddish brown, fine to medium, Silty SAND with 122.2 12.2 gravel 31 Reddish brown, find to coarse, Silty SAND with 126.8 10.4 some fine to coarse gravel and trace clay 32 Grayish olive-brown, fine to medium, Gravelly 144.0 6.3 SAND with trace silt LI Project No. 06105-12-07 March25, 2003
