The rough grading consisted of the grading of an eighteen hole golf course surrounded by residential building pads. As indicated in the previous geotechnical reports and summarized in the referenced Geotechnical Update, portions of the project site including some of the building pads were previously graded in 1988 as part of the East La Quinta Flood Control project. Due to the varying soils conditions on the site (including previously graded building pads), the extent of the remedial grading -work performed during rough grading varied across the site. Observations and field testing was performed during the rough grading operations from January 2, 1997 to April 4, 1997. Grading operations were performed by Nuevo Engineering using conventional heavy equipment. A representative of Sladden Engineering was present on the site continuously during the grading of building pads and intermittantly during the grading of golf course areas. July 30, 1997 (2) Project No. 522 -6138 -GI Field 'Pests: In-place moisture/density tests were performed using a nuclear density gauge in accordance with test methods ASTM D 2922 and ASTM D 30I7. A total of 1417 tests were performed during the initial rough grading. The approximate test locations are indicated on the grading plans included with this report and test results are summarized on the attached data sheets. Testing indicates that a minimum of 90 percent relative compaction was attained in the areas tested. The passing test results indicate compliance with the project specifications at the tested locations and depths but are no guarantee or warranty of the contractor's work. Laboratory 'Pests: The moisture -density relationships for the tested materials were determined in the laboratory in accordance with test method ASTM D 1557-91. Laboratory test results are summarized on the attached data sheet. Discussion: As previously discussed, the remedial grading performed at the site varied with location and soils conditions. Prior to grading, the building areas were stripped of weeds, brush and other surface vegetation. Clearing operations also included the removal of citrus trees and other trees from the lower (northern) portion of the site_ In general, remedial grading throughout the southern portion of the site consisted of watering and compaction of the native soils in-place along with the placement of engineered fill material to construct the building pads. Native soils were watered so that near optimum moisture content was attained to a minimum depth of three feet below original grade or four feet below pad grade, whichever was deeper. The exposed surface was compacted so that at least 90 percent relative compaction was attained to a depth of two feet below original grade or three feet below pad grade, whichever was deeper. In most areas, fill material obtained from the adjacent golf course areas was placed to construct the building pads. The lots graded as described above included lots 150 through 229 and 238 to 241. The majority of the lots located within the middle portion of the site were previously rough graded. These lots were cleared of weeds and brush and watered prior to grading. In general, grading consisted.primarily of some minor cuts and fills (some in excess of 10 feet) to achieve the plan elevations. In most cases, the building pads did not extend laterally beyond the previously graded building pads. In areas where the pads were extended substantially (such as along the rear property lines of lots 81 through 84), the fills were initiated within firm native soils near the toe of the slopes. A keyway was established near the toe of the slope and fill soils were benched into the existing slope during placement. The previously graded lots that were regraded as described above include lots 27 through 36 and lots 76 through 150. Slodden Engineering July 30, 1997 (3) Project No. 522-6138-G1 The remedial grading performed throughout the northern portion of the site included overexcavation and recompaction within the building areas. In general, lots were. overexcavated to a depth of at least three feet below original grade. The previously removed soils were replaced in thin lifts and compacted along with fill soils obtained from the nearby golf course areas to construct the building pads. The lots that were overexcavated include lots 1 through 26 and 37 through 75, and the maintenance building area Some of the residential lots have been used for the storage of rock, trees, other construction materials and excess fill soils subsequent to grading. Although some of these lots may require additional clearing or fine grading„ no degradation of the compacted fill material is expected. Fill material was stockpiled on lots 193 through 207 for use during the future grading of lots 230 through 236. The stockpiled material was not tested because it will be removed at a later date. Irrigation lines were encountered in the area of the existing pond and accessing the pond. The pond was removed during grading but some of the irrigation lines were left in place for future abandonment. These irrigation lines should be removed from building pads and roadway areas when abandonment is allowed. The resulting excavations should be properly backfilled and backfill material should be properly compacted. Recommendations: The allowable bearing pressures recommended in the original Geotechnical Engineering Report prepared by Buena Engineers, Inc. dated November 27, 1984 (B-14796-P1, 84-11-216) remain applicable. Conventional shallow spread footings should be bottomed in properly compacted fill material at least 12 inches below lowest adjacent grade. Continuous footings should be at least 12 inches wide and isolated pad footings should be at least two feet wide. Continuous footings and isolated pad footings may be designed utilizing an allowable bearing pressures of 1500 psf. An allowable increase of 200 psf for each additional six 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 acting along the base of the foundations and passive resistance along the sides of the footings. A friction coefficient of 0.45 times the normal dead load forces is suggested for use in design. Passive resistance may be estimated using an equivalent fluid weight of 300 pcf. If used in combination, we suggest that either the frcitional resistance or the passive resistance be reduced by one-third Siodden Engineering July 30, 1997 (4) Project No. 522 -6138 -GI Cantilever retaining walls should be designed using "active" pressures. Active pressures may be estimated using an equivalent fluid weight of 35 pcf. Walls that are restrained should be designed using "at rest" pressures. At rest pressures may be estimated using an equivalent fluid weight of 55 pcf. The given design pressures are applicable for free - drained level bacl fill conditions. The project site is located in a seismically active area and the potential for seismic activity should be considered in building design. In general, the Uniform Building Code requirements for Seismic Zone 4 should be adequate for the design of the planned residential structures. Because some of the site soils (primarily the silty sands and sandy silts encountered throughout the northern portion of the site) may be susceptible to settlements due to the introduction of excess moisture, care should be taken to minimize infiltration adjacent to building foundations. Positive drainage should be provided to direct water away from the structures. The ponding of water adjacent to buildings or paved areas should not be allowed. Proper grading should be performed to direct stormwater runoff away from structures and landscape irrigation should be minimized.

The project site is located at 78-271 Deacon Drive West 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. February 20, 2013 -2- Project No. 544-13032 13-02-065 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 2010 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. Based on our field observations and understanding of local geologic conditions, the soil profile type judged applicable to this site is SD, generally described as stiff soil. The following presents additional coefficients and factors relevant to seismic mitigation for new construction based upon the 2010 California Building Code (CBC). 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 1h second. This assumption should be verified by the project structural engineer. The 2010 CBC Seismic Design Parameters are summarized below.

Testing indicates that the site soil is generally considered non- corrosive with respect to concrete. The testing indicated soluble sulfate content of 350 ppm (0.035 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 is not required.
