J=' <br /> MW7M KLEINFELDER <br /> File No.: 20-3121-02 <br /> November 2, 1988 <br /> Page 5 <br /> CONCLUSIONS AND RECOMMENDATIONS <br /> General <br /> As discussed, the site contains a residence constructed on a fill pad level with <br /> Northland Road, approximately 4 to 5 feet above the majority of the site. The fill <br /> pad covers the approximate north 1/3 to 1/2 of the proposed building site. In our <br /> opinion, it will likely be desired to raise the proposed building pad and adjacent <br /> landscaping to the height of the existing pad and Northland Road. We anticipate the <br /> landscaping will slope off to the parking areas at the approximate existing grade. The <br /> following sections of this report present our recommendations for foundations, support <br /> of floor slabs, site preparation and grading, and pavements. The structure should, as a <br /> minimum, be designed to meet seismic requirements stipulated by the current Uniform <br /> Building Code for Seismic Zone 3. <br /> z � <br /> Foundations <br /> In our opinion, the structure can be supported on spread or continuous foundations <br /> bearing on the existing fill soils and/or properly placed Engineered Fill. We <br /> recommend that footings extend a minimum depth of 12 inches below the lowest <br /> adjacent finished soil subgrade, interior or exterior, whichever controls. If the <br /> structure is supported partially on the existing fill soils, we anticipate that loose soils <br /> will be exposed at the bottom of approximately 1/3 to 1/2 of the footing trenches. In <br /> order to provide more uniform foundation support, we recommend that the exposed soils <br /> be compacted with hand equipment prior to placing reinforcing steel. If deep <br /> extremely loose soil pockets• or debris pockets are encountered, they should be <br /> overexcavated and recompacted as described in the "Site Preparation and Grading" <br /> section of this report. <br /> s <br /> i <br /> f <br />
