The project site is located at 78-145 Masters Circle, Lot 90 within The Tradition Golf 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 Tradition Golf Club project site. The rough grading included over excavation and/or 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 grading report along with the compaction test results. The referenced reports include recommendations pertaining to the design and construction of residential structure foundations. 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. July 12, 2015 -2- Project No. 544-16182 16-07-275 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 1800 psf and 2000 psf, respectively. 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 of 0.48 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 2013 California Building Code (CBC) classification criteria. Slab thickness and reinforcement should be determined by the structural engineer, we recommend a minimum floor slab thickness of 4.0 inches. All slab reinforcement should be supported on concrete chairs to ensure that reinforcement is placed at slab mid -height. Because the lot has been previously graded, the remedial grading required at this time for the proposed residence should be minimal. 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. The seismic design category for a structure may be determined in accordance with Section 1613 of the 2013 CBC or ASCE7. According to the 2013 CBC, Site Class D may be used to estimate design seismic loading for the proposed structures. The 2013 CBC Seismic Design Parameters are summarized below. Risk Category (Table 1.5-1): I/II/III Site Class (Table 1613.3.2): D Ss (Figure 1613.3.1): 1.500g SI (Figure 1613.3.1): 0.601g Fa (Table 1613.3.3(1)): 1.0 Fv (Table 1613.5.3(2)): 1.5 Sms (Equation 16-37 {Fa X Ss}): 1.500g Sm1 (Equation 16-38 {Fv X Si}): 0.901g SDS (Equation 16-39 f2/3 X Sms)): 1.000g SDI (Equation 16-40 12/3 X Sml}): 0.601g Seismic Design Category: D Sladden Engineering www.Sladdenengineering. con: July 12, 2015 -3- Project No. 544-16182 16-07-275 In addition, we have sampled the surface soil on the subject lot to determine the soluble sulfate content as it relates to selecting appropriate concrete mix designs. Testing indicates that the site soil is generally considered non- corrosive with respect to concrete. The testing indicated soluble sulfate content of 1800 ppm (0. 18 percent) that corresponds with the "moderate" exposure category in accordance with ACI 318-08, Table 3. Based upon this, the use of sulfate resistance concrete mixes should not be required. Structural concrete placed in contact with soil should have a minimum compressive strength of 4000 psi and a maximum water/cement ratio of 0.50.

In addition, we have visited the site to observe the present conditions. These services were performed for update purposes and to provide specific recommendations for site development and foundation design. Based upon our review, it appears that the referenced reports contain useful information concerning the site soils conditions and the recommendations contained in the referenced reports remain valid for the design and construction of the proposed residential development. There are some recommendations included in the referenced reports that warrant clarification. Because the soils conditions vary throughout the site, the remedial grading recommended at this time also varies. The site bas been partially graded including the construction of building pads throughout the middle portion of the site. Testing performed during and after grading i.s summarized in the referenced reports prepared by Soil and Testing Engineers, Inc.(STE). Based upon the information contained in the STE reports, it appears that the fill material placed during the previous grading was properly compacted and should provide adequate support for the proposed residential structures. The previously graded building pads should be cleared of vegetation, moisture conditioned and recompacted to at least 90 percent relative compaction. Fill material may then be placed in thin lifts at near optimum moisture content and compacted to a minimum of 90 percent relative compaction. Any fill material placed along the existing slopes to construct the proposed building pads should be properly benched into the existing slopes. Fill slopes should be overbuilt and cutback to firm material_ December 12, 1.996 (2) Project No. 444-6130 The building pad areas throughout the northern portion of the site have not yet been graded and are generally underlain by loose sandy silts and silty fine grained sands. Building pads throughout the northern portion of the site should be overexcavated to a depth of three feet below existing grade. The previously removed soils should be placed in thin lifts at near optimum moiture content and compacted to a minimum of 90 percent -relative compaction. The building pad areas throughout the southern portion of the site have not yet been graded and are generally underlain by fine to coarse grained alluvial sands with gravel. Because of the granular nature of the alluvial soils throughout the southern portion of the site, it is likely that the desired depth of compaction can be attained by watering and compacting from the surface. Building pads throughout the southern portion of the site should be watered so that near optimum moisture content is attained to a depth of three feet below existing grade. The exposed surface should then be compacted so that a minimum of 90 percent relative compaction is attained to a depth of two feet below existing grade. Fill material should then be placed in thin lifts at near optimum moisture content and compacted to at least 90 percent relative compaction. The building pads proposed for the small canyon near the southern end of the site (see sheet S of rough grading plan) appear to require the construction of building pads partially in fill and partially in cut. In order to limit the potential for transition related differential settlements, we recommend overexcavation of the cut portion of these building pads. Dverercavation should extend to a depth of at least four feet below pad grade. Additional overexcavation to facilitate adequate boulder removal should be considered_ Because this area slopes considerably, proper benching will be very important during fill placement. The potential for rockfall affecting the building pads along the toe of steep natural rock slopes should be acknowledged. The potential rockfall hazard appears to be limited to several building pads along the south and cast edge of the site (see sheets 4, 5 and 8 of the rough grading plan). The drainage swales indicated along the toe of the native rock slopes as indicated on the rough grading plans appear to appropriately address rockfall hazards at this time. The rockfall hazard potential should be evaluated after rough grading and lot specific mitigation measures should be incorporated into individual fine grading plans and building layout deternunation. The allowable foundation bearing pressures and lateral values recommended in the referenced Preliminary Soil Investigation report remain applicable for the design of structure foundations. The remainder of the recommendations included in the referenced reports should be considered in design and construction.
