Geotechnical Investigation Cassia Road Project* prepared by Geocon Incorporated dated December 16 2004 (Project No 07431 2201) In accordance with a request from Mr Tom Guinn Southern California Soil and Testing Inc has prepared this report to provide preliminary retaining wall design recommendations for the masonry retaining walls for the subject project FOUNDATIONS Conventional shallow foundations may be utilized for the support of the proposed retaining walls The footings should have a minimum depth of 18 inches below lowest adjacent finish pad grade and a minimum width of 12 inches A bearing capacity of 3000 pounds per square foot (psf) may be assumed for said footings The bearing capacity may be increased by 300 psf and 500 psf for each additional foot of foundation width and depth respectively up to a maximum of 5000 psf The bearing capacity may be increased by one third when considering wind and/or seismic forces Footings located adjacent or within slopes should be extended to a depth such that a minimum horizontal distance of 10 feet exists between the outer footing edge and the face of the slope EARTH RETAINING WALLS Passive Pressure The passive pressure for the prevailing soil conditions may be considered to be 300 psf per foot of depth This pressure may be increased by 1/3 for seismic loading The coefficient of friction between concrete and the underlying material may be assumed to be 0 30 When combining fnctional and passive resistance friction should be reduced by 1A The upper 12 inches of soil should not be considered when calculating passive pressures for exterior walls I I I I I I I I I I I I I I I I I I I Ms Lynn Yut September 8 2006 All Cat s Hospital SCS& TNo 06111152 El Camino Real and Cassia St Carlsbad, CA Page 2 Active Pressure The active soil pressure for the design of unrestrained earth retaining structures with level backfills may be assumed to be equivalent to the pressure of a fluid weighing 40 pounds per cubic foot (pcf) This pressure does not consider any surcharge loads If any are anticipated this office should be contacted for the necessary increase in soil pressure These values assume a granular and drained backfill condition Waterproofing specifications and details should be provided by the project architect A typical wall subdram detail is provided on Plate No 1 Waterproofing and Subdrain Observation The geotechnical engineer should be requested to verify that waterproofing has been applied and that the subdram has been properly installed However unless specifically asked to do so, we will not verify proper application of the waterproofing Backfill All backfill soils should be compacted to at least 90 percent relative compaction Expansive or clayey soils should not be used for backfill material The wall should not be backfilled until the grout has reached an adequate strength Should you have any questions regarding this document or if we may be of further service please

accordance with a request from Mr Erik Nelson of Pacific Building Group this letter has been prepared to provide shoring recommendations for the subject project We understand improvements will consist of a road widening supported by a Keystone wall and a curb inlet structure The site is underlain by undocumented fill and formational material commonly identified as the Santiago Formation To determine the extent of the fill along the planned wall alignment SCS&T drilled 3 borings at the locations indicated on Figure 1 The fill was determined to range from approximately 10 to 25 feet in depth thickening to the south and east The fill consists of soft clays and loose clayey sands The boring logs are presented in Appendix I Laboratory testing performed on the sample is presented in Appendix II Shoring along El Camino Real will be required to support excavations for the construction of the planned wall and curb inlet structure It is anticipated that soldier beams with tiebacks and lagging will be utilized ranging from about 15 to 27 feet in height starting at wall Station 2+80 and ending at Station 4+00 Areas north and south of the shored area can be cut temporarily at an inclination of 1(H) 1(V) with a 5 foot vertical at the toe of the slope Cross section A A', Figure 2, shows the anticipated top and bottom elevation of the shoring along El Camino Real Typical sections through the most critical areas are shown on Figures 3 and 4 The design parameters to calculate the earth pressures on shoring are presented in Table 1 1 1 •1 1 1 • 1^w 1 1 • 1•1 1 1 • 1 1 O

shoring system that is unyielding and not able to rotate Construction surcharge loads should be evaluated on a case by case basis Soils should no be stockpiled at the top of slopes or at the top of the shoring Vertical and lateral movements of the temporary shoring are expected to be small assuming an adequate lateral support system If any other surcharge loads are anticipated SCS&T should be contacted for the necessary increase in soil pressure The passive pressure for the design of the proposed shoring system may be considered to be 350 psf per foot of depth up to a maximum of 5 000 psf The passive pressure may be assumed to act on an area equal to twice the soldier beam diameter This value may be increased by 1/3 for seismic loading The upper 1 foot of embedment should be neglected when calculating passive pressures Survey monuments should be installed at no more than 40 foot intervals along the perimeter of the excavation One row of monuments should be located just beyond the edge of the top of excavation A second row should be established 10 feet beyond the excavation, and a third row should be set 20 feet from the top of the excavation A reference point should be established well away from the block where the excavation will take place The horizontal and vertical location of each monument should be established with a survey instrument before excavation starts Readings should be made daily during the initial stages of excavation say for up to one week Results of the initial readings will be reviewed by SCS&T and modifications to the monitoring schedule may be made depending on these results Significant sloughing and erosion of the slopes should be anticipated In addition construction activities above or near the slopes could affect overall stability The slopes should be observed by a representative of SCS&T periodically to ascertain that no unforeseen adverse conditions are observed The temporary slopes should be inspected daily by the contractor s Competent Person before personnel are allowed to enter the excavation Zones of potential instability sloughing or raveling should be brought to the attention of the Engineer and corrective action si 1
