In addition, we have visited the project site to observe the present conditions and sampled the surface soil to determine soluble sulfate content. The Rancho Santana project site is located on the southwest corner of Monroe Street and Avenue 52 in the City of La Quinta, California. The referenced Geotechnical Investigation report includes recommendations for remedial site grading and the design and construction of residential structure foundations. Based upon our review of the referenced reports and our recent site observations, it is our opinion that the recommendations included in the referenced Geotechnical Investigation report remain applicable. The structural values included in the referenced report should be applicable for use in the design of the residential structure foundations. Conventional shallow spread footings should be at least 12 inches deep and bottomed into firm compact engineered fill soil. Continuous footings at least 1 foot wide and isolated pad footings at least 2 feet square may be designed using allowable bearing pressures of 1500 and 1800 pounds per square foot (psf), respectively. Allowable increases of 200 psf for each additional 1 foot of width and 300 psf for each additional 6 inches of embedment depth may be utilized. The maximum allowable bearing pressure should be 2500 psf. The allowable bearing pressures are for dead and frequently applied live loads and may be increased by 1/3 to resist wind, seismic or other transient loading. aJ s EIU'C July 25, 2017 -2- Project No. 544-3001 17-07-3 l 5 Settlements may result from the anticipated foundation loads. These estimated ultimate settlements are calculated to be a maximum of 1 inch when using the recommended bearing values. As a practical matter, differential settlements between footings can be assumed as one- half of the total settlement. These elastic settlements are expected to occur during construction. Resistance to lateral loads may 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 0.40 between soil and concrete may be used for dead load forces only. A passive earth pressure of 250 pounds per square foot, per foot of depth, may be used along the sides of footings that are placed against properly compacted soil. Passive earth pressure should be ignored within the upper 1 foot except where confined (such as beneath a floor slab). The bearing soil is non -expansive and falls within the "very low" expansion category in accordance with 2016 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. Slabs with moisture sensitive surfaces should be underlain with a moisture vapor retarder consisting of a polyvinyl chloride membrane such as 10-mil Visqueen, or equivalent. All laps within the membrane should be sealed and at least 2 inches of clean sand should be placed over the membrane to promote uniform curing of the concrete. To reduce the potential for punctures, the membrane should be placed on a pad surface that has been graded smooth without any sharp protrusions. If a smooth surface can not be achieved by grading, consideration should be given to placing a 1-inch thick leveling course of sand across the pad surface prior to placement of the membrane. It is our opinion that the remedial grading initially performed including overexcavation and recompaction of the surface soil within the proposed building areas remains applicable. Because the pads have been rough graded, the remedial grading necessary at this time should be minimal. The building pad areas should be cleared of any surface vegetation and root systems prior to grading. The exposed surface should be scarified, moisture conditioned and compacted to a minimum of 90 percent relative compaction. Fill material may then be placed in thin lifts at near optimum moisture content and compacted to at least 90 percent relative compaction. Compaction should be verified by testing. The seismic design category for a structure may be determined in accordance with Section 1613 of the 2016 CBC or ASCE7. According to the 2016 CBC, Site Class D may be used to estimate design seismic loading for the proposed structures. This assumption should be verified by the project structural engineer. The 2016 CBC Seismic Design Parameters are summarized on the following page. Sladden Engineering July 25, 2017 -3- Project No. 544-3001 17-07-315 Risk Category (Table 1.5-1): I/11/III Site Class (Table 1613.3.2): D Ss (Figure 1613.3.1): 1.585g S1 (Figure 1613.3.1): 0.750g Fa (Table 1613.3.3(1)): 1.0 Fv (Table 1613.5.3(2)): 1.5 Sms (Equation 16-37 (Fa X Ss}): 1.585g Sm1 (Equation 16-38 (Fv X S1}): 1.125g SDS (Equation 16-39 (2/3 X Sms}): 1.057g SM (Equation 16-40 12/3 X Sml}): 0.750g Seismic Design Category: E In addition, we have sampled the surface soil on the subject site 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 760 ppm (0.076 percent) that corresponds with the "negligible" exposure category in accordance with ACI 318-08, Table 3. Based upon this, the use of sulfate resistance concrete mixes should not be required. If you have questions regarding this letter or the referenced reports, please contact the undersigned.
