Ref: .Geotechnical Investigation Report prepared by Sladden Engineering dated January
28, 2005; Project No. 544-4810, Report No. 05-01-101.
Report of Testing and Observation during. Rough Grading prepared by Sladden
Engineering dated March 2, 2006; Project No. 522-4810; Report No. 06-02-120
As requested, .we have reviewed the above referenced geotechnical reports as they relate to the
design and construction of the proposed custom residence. The project site is located at 81307 &
81325 Amundson Avenue within the Madison Club development in the City of La Quinta,
California. 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.
The lot was previously graded during the initial 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
referenced Project Grading Report along with the compaction test results.
The referenced reports include recommendations pertaining to the construction of residential
structure foundations. The previous reports also address the potential for liquefaction,
subsidence and differential settlement. The remedial grading performed was intended to
mitigate potential differential settlements.. 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..

Allowable increase of 200 psf for each additional 1 foot of width and 250 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. Increases in allowable bearing pressures may be realized with increased
footing size.
Resistance to lateral loads can be provided by a .combination of friction acting at the base of the
slabs or foundations and passive earth pressure along the sides of the foundations. A coefficient
of friction of0.48 between soil and concrete may be used with dead load forces only. A passive
earth,pressure of 300 pounds per square foot, per foot of depth, may be used for the sides of
footings, which are placed against properly compacted native soils.
The bearing soil is non -expansive and falls within the "very low" expansion category in
accordance with the 2007 CBC classification criteria. Pertinent 2007 CBC Seismic Design
parameters are summarized on the attached data sheet.
Because the lot has been previously graded, the remedial grading required at this time should be
minimal provided that the residence falls within the building envelopes established during rough
grading. The building areas should be cleared of surface vegetation, scarified and moisture
conditioned prior to- precise grading. The exposed surface should be compacted so that a
minimum of 90 percent relative compaction is attained prior to fill placement. Any fill material
should be placed in thin lifts at near optimum moisture content and compacted to at least 90
percent relative compaction. If .building elements extend beyond the rough .graded pad,
additional overexcavation will be necessary.
Based on our field observations and understanding of local geologic conditions, the soil profile
type judged applicable to this site is Sn, generally described as stiff soil. The following presents
additional coefficients and factors relevant to. seismic 'mitigation for new construction upon
adoption of the 2007 California Building Code (CBC).
The seismic design category for a structure may be determined in accordance with Section 1613
of the 2007 CBC or ASCE7. According to the 2007 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 1/2 second. This assumption should be verified by the project structural engineer. The 2007
CBC Seismic Design Parameters are summarized on the following page.
