It is our understanding that the proposed residential structure will be of relatively lightweight wood - frame construction and will be supported by conventional shallow spread footings and concrete slabs on grade. 1 The lots were previously graded during the rough grading of the Madison Club project site. The rough grading included recompaction of the native surface soil along with the placement of engineered fill material to construct the building pads. The site grading is summarized in the 1 referenced report of Testing and Observation During Rough Grading along with the compaction test results. ' Because the lots have been previously rough graded, the remedial grading required at this time should be minimal provided that the building area that falls within the previously assumed building envelopes. The building areas should be clea ed��f-sur ace vegetation, scarified and moistttre conditioned prior to precise grading.

The previous reports also address the potential for liquefaction, ' subsidence and differential settlement. Based upon our review of the referenced reports, it is our opinion that the structural values included in these reports remain applicable for the design and construction of the proposed residential structure foundations. ' The allowable bearing pressures recommended in the referenced Geotechnical Investigation report remain applicable. Conventional shallow spread footings should be bottomed into properly compacted fill material a minimum of 12 inches below lowest adjacent grade. Continuous footings should be at least 12 inches wide and isolated pad footings should be at least 2 feet wide. Continuous footings and isolated pad footings should be designed utilizing ' allowable bearing pressures of 1500 psf and 2000 psf, respectively. Allowable increases of 300 psf for each additional 1 foot of width and 300 psf for each additional 6 inches of depth may be utilized, if desired. The maximum allowable bearing pressure should be 3000 psf. The ' recommended allowable bearing pressures may be increased by one-third for wind and seismic loading. ' Lateral forces may be resisted by friction along the base of the foundations and passive resistance along the sides of the footings. A friction coefficient of 0.48 times the normal dead load forces is recommended for use in design. Passive resistance may be estimated using an equivalent fluid weight of. 300 pcf. If used in combination with the passive resistance, the frictional resistance should be reduced by one third to 0.33 times the normal dead load forces. The bearing soil is generally non -expansive and falls within the "very low" expansion category in ' accordance with the 2010 (CBC) classification criteria. Pertinent 2010 CBC Seismic Design parameters are summarized on the following page. t Based on our field observations and understanding of local geologic conditions, the soil profile type judged applicable to this site is So; generally described as stiff soil. The site is located within UBC Seismic Zone 4. The additional coefficients and factors relevant to seismic mitigation for new construction in accordance with the 2010 California Building Code (CBC) are provided in this report.

APPROVED tFO C N UCTI N DATE I Sladden Engineering May 3, 2012 -3- Project No. 54442071 12-05-111 The seismic design category for a structure may be determined in accordance with Section 1613 of the 2010 CBC or ASCE7. According to the 2010 CBC, Site Class D may be used to estimate design seismic loading for the proposed structures. The period of the structures should be less than lh second.
