Box 367 La Quinta, California 92253 Subject: Geotechnical Evaluation Report Project: 49-805 Lago Drive, La Quints Country Club La Quinta, California This Geotechnical Evaluation Report is prepared for the evaluation distress to the existing condominium residence in the City of La Quinta, California. The condominium residence is a single -story, wood -frame and stucco structure on concrete slab -on -grade. Another unit is attached to the south. The primary observed distress to structure occurs as cracks in the concrete floor slab, tile flooring, walls, and exterior flatwork. Purpose and Scope of Work The purpose for our services was to evaluate the site soil conditions and to provide professional opinions and recommendations regarding the remedial repairs to the structural distress to the residence. The scope of work included the following: ➢ A general reconnaissance of the site. ➢ Liquid level survey of the lower interior floor. ➢ Shallow subsurface exploration by drilling two exploratory borings to a depth of 10'/z to 15'/z feet. ➢ Laboratory testing of selected soil samples obtained from the exploratory borings. ➢ Review of selected published technical literature pertaining to the site and previous geotechnical reports prepared for La Quinta Country Clubhouse, near the residence. ➢ Engineering analysis and evaluation of the acquired data from the exploration and testing programs.

An arbitrary base elevation of zero ("0") was set at the front foyer entrance. The purpose of the floor level survey is to evaluate relative differential elevations of the floor. A 10 x 10 -foot grid pattern was used throughout. The results of the floor level survey are shown on the attached floor level survey plan, using a computer-generated contour map from SURFER. The results of the floor level survey indicate that as much as 2.9 inches of differential settlement may have occurred since construction of the unit. The relative high is at the southwest corner with the unit tilting towards the northeast. The relative tilt ratio is as great as 1:75 across a 10- foot span. Most ,of the slab tilt occurs at the central and southeastern parts of the unit with a relative change in tilt occurring across the northern third of the unit. Field Exploration Two exploratory borings were drilled to a depth of about 10'/2 to 15'/Z feet below the existing ground surface to observe the soil profile and to obtain samples for laboratory testing. The borings were drilled on September 4, 2003 using a 3 -inch outside diameter hand auger. The boring locations are shown on the boring location plan attached to this report. Samples were obtained within the test borings using a Modified California (MC) ring sampler. The MC sampler has a 3 -inch outside diameter and a 2.37 -inch inside diameter. The samples were obtained by driving the sampler with a sliding hammer. Recovered soil samples were sealed in containers and returned to the laboratory. Bulk samples were also obtained from auger cuttings. The final logs of the borings represent our interpretation of the contents of the field logs and the results of laboratory testing performed on the samples obtained during the subsurface investigation. The final logs are attached to this report. Laboratory Testing Samples were reviewed along with field logs to select those that would be analyzed further. Test results are attached to this report. Our testing program consisted of the following: In-situ Moisture Content and Unit Dry Weight for the ring samples (ASTM D 2937). , Soil and Groundwater Conditions The field exploration indicates that site soils consist of variable layers of silty Sand, sandy Silt, Silt, with interbedded layers of clayey silt and clay. The boring logs attached to this report include more detailed descriptions of the soils encountered. The upper soils are visually classified to be in the very low expansion category in accordance with Table 18A -I -B of the Uniform Building Code. . EARTH SYSTEMS SOUTHWEST September 26 2003 3 P � File No.: 09332-01 03-09-815 Groundwater was not encountered in the borings. The depth to groundwater in the area is believed to be about 110 feet, based on recent water well data obtained from the Coachella Valley Water District. Groundwater levels may fluctuate with regional drawdown, irrigation, drainage, and site grading. We have reviewed Coachella Valley Water District water well records and hydrographs for several wells near the La Quinta Country Club. These hydrographs indicate that groundwater levels have dropped dramatically, 31 to 70 feet, in the north La Quinta cove area in the last twenty years. This corresponds to the increased water usage from the rapid growth of the City of La Quinta and golf course development. Geologic Setting Regional Geology: The site lies within the Coachella Valley, a part of the Colorado Desert geomorphic province. A significant feature within the Colorado Desert geomorphic province is the Salton Trough. The Salton Trough is a large northwest -trending structural depression that extends from San Gorgonio Pass, approximately 180 miles to the Gulf of California. Much of this depression in the area of the Salton Sea is below sea level. The Coachella Valley forms the northerly portion of the Salton Trough. The Coachella Valley contains a thick sequence of sedimentary deposits that are Miocene to recent in age. Mountains surrounding the Coachella Valley include the Little San Bernardino Mountains on the northeast, foothills of the San Bernardino Mountains on the northwest, and the San Jacinto and Santa Rosa Mountains on the southwest. These mountains expose primarily Precambrian metamorphic and Mesozoic granitic rocks. The San Andreas Fault zone within the Coachella Valley consists of the Garnet Hill Fault, the Banning Fault, and the Mission Creek Fault that traverse along the northeast margin of the valley. Local Geolo&y: The residence lies at an elevation of about 45 feet above mean sea level in the lower part of the La Quinta Cove portion of the Coachella Valley. The La Quinta Cove is situated on an alluvial wedge between two granite mountain spurs of the Santa Rosa Mountains. The area was at one time covered by the waters of ancient Lake Cahuilla. The sediments within the lower cove area consist of fine to coarse-grained sands with interbedded clays, silts, and gravels of aeolian (wind-blown), alluvial (water laid), and lacustrine (lake bed) origin. Geohydologic Setting: The site lies within the Thermal subbasin of the Coachella Valley groundwater basin. The Thermal subbasin is subdivided into four generalized zones: a semi perched zone with alternating clay layers to about 100 foot depth, underlain by a upper and lower aquifer, separated by an aquitard layer. Domestic wells in the region derive their water from the upper and lower aquifers, generally from about 200 to 1000 feet deep. Seismic Sources: Several active faults or seismic zones lie within the vicinity of the La Quinta area. The primary seismic hazard to the residence is strong groundshaking from earthquakes along the San Andreas and San Jacinto Faults that lie about 7 and 19 miles distant, respectively. EARTH SYSTEMS SOUTHWEST September 26, 2003 4 File No.: 09332-01 03-09-815 Conclusions The following is a summary of our conclusions and professional opinions based on the data obtained from a review of selected technical literature and the site evaluation. • The observed distress to the condominium residence is significant and classifies as "moderate to severe". Differential settlement of about 2.9 inches may have occurred. This movement appears to be progressive. Significant cracks were observed in the floor slabs and tile flooring as well as in exterior flatwork around the vicinity of the residence. • The angular distortion as great as 1:75 across the floor slab exceeds the normal expected construction tolerances of 1:300 (1 in/25 ft) where first cracking in panel walls can be expected: • In our opinion, land subsidence from groundwater withdrawals is the most plausible cause of the observed distress. Land subsidence occurs when the groundwater levels drop to cause an increase in effective overburden stress to underlying sediments and resulting in further consolidation of these sediments. As the sediments consolidate to this increased stress, subsidence of the ground occurs. Differential and potential detrimental settlement occurs when the underlying sediments consolidate in an uneven amount. Based on previous studies we have conducted for the adjacent clubhouse facility, we believe that the residence lies near the edge of an inferred and deeply buried mountain ridge that is causing this differential settlement to the residence and lateral extension of cracks. Land subsidence as been documented in this area of the La Quinta cove from recent U.S. Geological Survey studies using satellite GPS and radar surveys. Recommendations The building is repairable and may be relatively stabilized by underpinning the foundation with helical anchors. The advantage of the helical anchor system is that it can be readjusted as further movement may occur. Further progression of settlement may be expected over time as land subsidence continues from further groundwater withdrawals. We recommend the AB Chance Helical Anchor system as a means of providing stability to the foundation of the residence. The foundation underpinning is intended to give more rigidity to the structure and the ability to lift relative low areas. Floor slab underpinning supports may also be considered. A copy of this report should be forwarded to the structural engineer and specialty contractor, RJG Construction Company of Canyon County, California (Contact: Mr. Ken Drake, 661-298-1192). We recommend that Mr. Dilip Khatri of Khatri International of Pasadena, California (Telephone No. 626-685-9480) be contacted to provide a structural remediation plan. As an alternate, Mr. Grey Riley (Telephone No. 661-387-5800) may be used. Both are registered engineers who are familiar with the AB Chance Helical Anchor system. For the purposes of the design of the helical anchors, the relevant soil parameters are: unit weight of 95 pcf, friction angle of 32 degrees, and cohesion of 100 psf. In that this unit is attached to another unit, consideration should be given as to the impact of foundation stabilization on each unit. For the modjacking option to relevel the floor slabs (a non-structural element of the residence), a specialty contractor may be used. We recommend either Hayward -Baker of San Diego, EARTH SYSTEMS SOUTHWEST September 26, 2003 5 File No.: 09332-01 03-09-815 California (Contact: Greg Thornton, 858-514-2170) or Jeff Garaci of Moore & Taber of Anaheim, California (Telephone No. 714-779-0681). After the foundation underpinning and any leveling adjustments made, the cracked tile should be replaced and wall cracks patched. Limitations Our findings and recommendations in this report are based on selected points of field exploration, laboratory testing, and our understanding of the proposed project. Furthermore, our findings and recommendations are based on the assumption that soil conditions do not vary significantly from those found at specific exploratory locations. Variations in soil or groundwater conditions could exist between and beyond the exploration points. The nature and extent of these variations may not become evident until construction. Variations in soil or groundwater may require additional studies, consultation, and possible revisions to our recommendations. Findings of this report are valid as of the issued date of the report. However, changes in the conditions of a property can occur with passage of time, whether they are from natural processes or works of man, on this or adjoining properties. In addition, changes in applicable standards occur, whether they result from legislation or broadening of knowledge. Accordingly, findings of this report may be invalidated wholly or partially by changes outside our control. Therefore, this report is subject to review and should not be relied upon after a period of one year. This report is issued with the understanding that the owner or the owner's representative has the responsibility to bring the information and recommendations contained herein to the attention of the engineers for the project so that they are incorporated into the plans and specifications for the remedial repairs. The owner or the owner's representative also has the responsibility to take the necessary steps to see that the general contractor and all subcontractors follow such recommendations. It is further understood that the owner or the owner's representative is responsible for submittal of this report to the appropriate governing agencies. Earth Systems Southwest (ESSW) has striven to provide our services in accordance with generally accepted geotechnical engineering practices in this locality at this time. No warranty or guarantee is express or implied. This report was prepared for the exclusive use of the Client and the Client's authorized agents. ESSW should be provided the opportunity for a general review of remedial plans and specifications in order that our recommendations may be properly interpreted and implemented in the design and specifications. If ESSW is not accorded the privilege of making this recommended review, we can assume no `responsibility for misinterpretation of our recommendations.
