Carlsbad California 92010 (760) 438-3155 FAX (760) 931-091.5 August 16, 2007 W.0. 5355-D-SC Calavera Hills II, LLC 2750 Womble Road San Diego, California 92106 Attention Mr. Don Mitchell Subject Compaction Report of Geotechnical Observation and Testing Services, 84-Inch Storm Drain Improvements for Cannon Road, Robertson Ranch East Village, Carlsbad, San Diego County, California, Carlsbad, San Diego County, California Dear Mr. Mitchell This report presents a summary of the geotechnical engineering observation and testing services provided by GeoSoils Inc.'(GSI) during the observation and testing of the 84-inch storm dran located along the north side of Cannon Road, approximately between the intersection of Cannon Road and El Camino'.Real and Cannon Road and College Boulevard, in the City of Carlsbad, San Diego County California Observation and testing services were provided by GSI during the period from May 2007 through August 2007 TRENCH CONSTRUCTION/BACKFILL Backfill operations were observed by GSI personnel on an as-needed basis as solely determined by the Client/Contractor. Observations and testing guidelines are provided as follows o During trenching operations, the trench bottom was observed by a representative from this office to be relatively firm and considered suitable for the support of the structure 3/4-inch rock (GSI 2007a and 2007c) was observed to be placed within the pipe zone, from the bottom of trench to about spring line, in general accordance with the approved plan Select soil (both import and native per GSI [2007a and 2007b]) with a sand equivalent of at least 30 was placed from about spring line to at least ± 1 foot over the top of pipe, in general accordance with the approved plan Native onsite soils were used as trench backfill above the zone of select soil, from 1 foot above the top of pipe to finish grade. The maximum allowable size of rock fragments (when present) within the backfill satisfied the governing agency guideline. The minimum compaction required was 90 percent of the laboratory standard (ASTM D-1 557) for select soil and native backfill. FIELD TESTING Field density tests were performed using the nuclear (densometer) ASTM D-2922 and ASTM D-3017 and the sand-cone method ASTM D-1 556. The test results are presented in the attached Table 1. Field density. tests were taken at periodic intervals and random locations to check the compactive efforts provided by the contractor. Where test results indicated a less than the required minimum compaction, the contractor was notified and the area was reworked until the required minimum relative compaction was-achieved for each respective area. Testing was provided on an as-needed basis as solely determined by the Client/Contractor. 3. Visual classification of the soil in the field was the basis for determining the maximum density value to use for a given density test. LABORATORY TESTING The laboratory maximum dry density and optimum moisture content for each of the major soil types were determined according to test method ASTM D-1 557. Corrected values for the percentage of rock in a given sample were used in the determination of relative compaction. The following table presents the results: SOIL -- MAXiMUM DRY MAXIMUM DRY• IMID SOIL TYPE DENSITY (PCF) .• CONTENT (%)• TYPE DENSITY (PCF CONTENT(%) A 134.5 8.0 E 126.0 11.0 B .127.5 10.5 H 134.0 9.0 C 120.5 10.5 N 122.5 12.5 Additional laboratory testing procedures and results regarding the quality of pipe zone backfillarë presented in GSl (2007a, 2007b, and 2007c).
