It is our professional opinion that the site is suitable for the proposed design and construction given the recommendations presented in this report are followed. We anticipate that AGEC will continue to provide geotechnical consultation, construction observations and field testing during construction. The following is a brief summary of geotechnical information related to preparing the site for development. • Short term (primary) settlement of the fine-grained tailings is significant and will likely continue for an extended time period following placement of site grading fill, preloads and structural loads . Settlement monitoring should be conducted to determine w hen the significant portion of the settlement has occurred and when construction may begin. • Building areas above the highly compressible tailings should be preloaded as described in the report . • The geotechnical engineer should review project plans relating to construction near and along slopes for conformance to the recomme ndations presented in the report. • A • rep resentative of the geotechnical engineer should observe foundation excavations and subgrade areas prior to concrete or fill placement. 2. Up to approximately 58 feet of tailings was encountered at the site. Th e tailings generally consist of fine and coarse-grained materials. The fin•e- grained tailings were generally encountered in areas of tailing ponds and low areas across the site. Coarse tailings were encountered in areas of dikes and embankments which extend throughout the tailings area. Based on a review of aerial photographs of the tailing areas, we anticipate that the majority of the site contains fine grained and/or compressible tailing s associated with the tailing ponds. Additional fill (non-tailings) was encountered along the northeast portion of the site and along the west and south perimeter slopes of the site. Th e fill consists of clayey sand and sa ndy lean clay. Buried concrete structures and small to moderate amounts of debris, wood, organics and metal was encountered in the a rea of Test Pits TP-1 through TP-3. Av~"'\; APPLIED GEOTECHNICALENGINEERING CONSULTANTS, P.C. 1040 194 Page 2 Executive Summary Continued The natural soil encountered below the fill and tailings consists of lean clay, sand and gravel. 3. Subsurface water was encountered in many of the explorations. The subsurface water was encountered at elevations ranging from 4,228 to 4,241 feet. PVC pipe was installed in Borings 8 -2 through 8-4 and Test Pits TP-4 through TP-6 to facilitate future measurement of the water level. The surface of the subsurface water level generally slopes down to the Jordan River. Additional information related to the subsurface water level is presented in the report. 4. Settlement at four preload areas is being monitored. Two of the areas are located where significant amounts of compressible tailings are anticipated. The third area is an area of less compressible subsurface conditions (generally coarse tailings and granular material with higher in-place densities). The third and fourth areas are adjacent the 3 horizontal to 1 vertical side slopes . Approximately 15 feet of fill was placed in the preload areas. Settlement plates were established and elevations measured by others. The settlement data was provided to AGEC for evaluation. The settlement monitoring has been conducted for a relatively short period of time (up to approximateJy 210 days through December 6, 2004). Based on the available data, approximately 8 to 15 ½ inches (averag e of 10.3 inches) of settlement has been measured in the compressible tailings areas. Approximately 2 to 5 ½ inches (average of 3.1 inches) of settlement has been measured in the areas with less compressible tailings. We anticipate that the primary settlement of the coarse grained tailings will occur rather quickly, likely during fill place ment. The settlement monitoring data i ndicates that the prim ary settlement of the fine grained tailings continues. Based on our analysis, we estimate that the primary settlement may continue for up to approximately 19 months. Additional information rel ated to the magnitude and estimated time for settlement to occur is presented in the repo rt. Placing fill in addition to the proposed site grading fill will reduce the preload time. Generally, doubling the h eight of the fill will halve the estimated time for settlement. Placement of additional fill may reduce the time for settlement to occur to approximately 4 ½ to 9 ½ months . Settlement monitoring should be conducted to determine when the significant portion of the settlement has occurred and whe n construction of se ttlement sensitive structures may begin. Av'b"\:' APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 3 Executive Summary Continued 5. Based on a review of old aerial photographs of the tailings site and due to the fine grained compressible materials encountered at the site, building areas within the area indicated on Figure 4 should be preloaded based on the anticipated change in stress due to the proposed structures. Additional information relating to building preloads are presented in the report. 6. Based on our understanding of the proposed construction and the subsurface conditions encountered, the proposed structures may be supported on spread footings bearing on the undisturbed natural soil, compacted structural fill extending down to the undisturbed natural soil or above the existing tailing areas which are preloaded, monitored for settlement and determined that the significant portion of settlement has occurred prior to building construction . Deep foundation systems may also be considered to provide higher load carrying capacity or to facilitate construction along the existing side slopes . Foundation recommendations such as allowable bearing pressures, estimated settlements are presented in the report. 7. A slope stability analysis indicates that the 3 horizontal to 1 vertical side slopes have safety f actors of at least 1.5 and 1 .0 for the static and seismic conditions, respectively. Additional information related to slope stability is presented in the report. 8. A site specific liquefaction analysis was conducted in conjunction with the study. Based on our liquefaction analysis, it is our professional opinion that liquefaction of the natural soils encountered at the site is not a hazard for the proposed development. However, liquefaction could be a concern if the water level were to rise up in to loose, granular tailings. Additional information related to the liquefaction potential at the site is presented in the report. 9. Geotechnical information relating to foundations, subgrade preparation, compaction, materials and pavement design is included in the report. Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 4 SCOPE This report presents the results of a geotechnical investigation for the conceptual and preliminary design of the proposed Jordan Bluffs Development, "Sharon Steel Site" to be located at approximately 7800 South 700 West in Midvale, Utah. The report presents the subsurface conditions encountered, laboratory test results and recommendations for conceptual and preliminary design and site grading. The study was conducted in general accordance with our proposal dated March 12, 2004 with the exception of conducting fewer borings at the site. A proposed work plan was provided in a letter dated April 26, 2004. The scope of work was modified as the investigation proceeded. Environmental Resources Management (ERM) previously conducted a preliminary geotechnical evaluation of the Sharon Steel Superfund Site -Midvale, Utah for Mercury Financial and presented their preliminary findings and recommendations in a report dated February 2, 2004. Field exploration was conducted to obtain information on the subsurface conditions. Samples obtained during the field investigation were tested in the laboratory to determine physical and engineering characteristics of the on-site tailings and soil. Information obtained from the field and laboratory was augmented with the information presented in the above referenced report and was used to define conditions at the site for our engineering analysis and to develop recommendations for the conceptual/preliminary design and site grading. This report has been prepared to summarize the data obtained during the study and to present our conclusions and recommendations based on the proposed construction and the subsurface conditions encountered. Preliminary design parameters and a discussion of geotechnical engineering considerations related to construction are included in the report. Av/:..'\; APPLIED GEOTECllNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 5 HISTORY The Sharon Steel site was previously used for ore milling and smelting. We understand that smelting and milling was discontinued in the late 1950's and early 1970's, respectively. Tailings were placed throughout the majority of the site. Aerial photographs indicate that much of the tailings were hydraulically placed or "pushed out" over previously placed fill or embankments. Windblown mill tailings accumulated in areas surrounding the site. Two areas were established at the site to receive off-site soil generated during remediation work in the adjacent areas surrounding the tailings site. We understand that materials deposited in these areas may have been placed in a controlled manner and tested for compaction. However, documentation of these activities could not be located. The tailings area was capped with a geosynthetic liner and a soil protective cover layer. The liner system consists of a geocomposite drain (textile and net) overlying a geomembrane overlying a geosynthetic clay liner. The cap and liner system extends across the majority of the site and along the north, south and west side slopes. We understand that remnants of the historic mill and smelter buildings remain along the northeast corner of the site. The above grade portion of these structures have been removed from the site, however, the basements, foundations and other below grade portions of these structures remain on site. Some of these structures were encountered during our field investigation (Test Pits TP-1 through TP-3). Photographs are presented in Appendix IV. SITE CONDITIONS The site consists primarily of an abandoned smelter and mill tailings area. The tailings area has been built up above the adjacent Jordan River low areas. There are 3 horizontal to Mb if n&1 t i ;w• Av£'\; APPLIED GEOTECIINICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 6 1 vertical side slopes along the north, west and south sides of the capped tailings area. The cap generally slopes down to the west with a series of peaks and valleys providing surface drainage to the west. There is up to approximately 16 feet of elevation difference between the peaks and valleys along the west side of the cap. Vegetation along the cap consists of grasses and weeds. The area along the northeast portion of the site has been rough graded for preconstruction access. We understand that buried foundations and other concrete structures exist along the northeast portion of the site. Vacant land extends along the east/central portion of the site (between 700 West Street and the cap). Undeveloped land extends along the southeast portion of the site between 700 West Street and the southeast portion of the cap. 700 West Street, which is a wide, two-lane, asphalt-paved road, extends along the east side of the south and central portions of the site. There are one and two-story, wood frame residences, one and two-story, slab-on-grade apartment structures and other buildings northeast of the site. 7800 South Street, which is a wide, asphalt-paved road, extends along the north side of the site. The Jordan River extends along the south and west sides of the capped area. FIELD STUDY The field study consisted of several phases of investigation. The approximate investigation locations are presented on Figures 1 and 2. &t uww r ~ @mu "W"51Ii M¾dHr1 1 ffiffi¼L.E i t:rt:mmTfrzr:r:rym & FF IU&ij l WA Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 7 Four borings (B-1 through 8-4) were drilled in the central portion of the site on April 27, 29 and 30, 2004. The boring locations were selected based on a review of old aerial photographs of the area . Borings 8-1 and 8-2 were located in tailings pond ar~as and where tailings were likely placed with water (s ee Figure 3). We anticipate that saturated tailings and water were allowed to stand in these areas for significant lengths of time . Boring 8 -3 was located in the central portion of the site in an area of anticipated improved subsurface conditions. Boring 8-4 was located along the south side of the site adjacent to embankment side slope. Boring 8-4 is located along the south end of the site in an area which likely received non-tailing fill material placed in a "controlled" manner. A representative of Utah Division of Environmental Quality was on -s ite during initial drilling and periodically during the remainder of the field study. The soil protective cover at each boring location was excavated by hand to expose the geosynthetic liner materials. Approximately 1 to 1 ½-foot square holes were cut through the liner to allow for auger drilling below the liner. The borings were drilled using 8-inch diameter hollow-stem auger powered by an all-terrain drill rig. The borings were logged by a representative from AGEC. The borings were drilled to observe the subsurface profile, to obtain samples for laboratory testing and to measure the depth to groundwater. PVC pipe was insta ll ed in Borings B-2, 8 -3 and 8-4 to allow for future measurement of the subsurface water levels. The pipes were slotted near the anticipated free water l evel. Generally, the borings were b ackfilled with silica sand below the free water level and below the tailings/natural soil interface. Approximately 3 to 8 feet of bentonite was placed in the borings around the PVC pipes above the sand. Cuttings (tailings) from the drilling process were used as backfill above the bentonite up to the liner. Add itional on-s ite soil was used where need ed to place fi ll up to near the liner e levation. We understand that the portion of the pipes extend ing above grade is planned to b e cut off, the liner r epaired and soil protective cover replaced. We understand that this work will b e accompli shed by others. Av6"\;' APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 8 The auger drilling investigation was followed by cone penetration testing (CPT). Six CPT soundings were conducted at the approximate locations indicated on Figure 1 on May 13, 2004. The CPT locations were selected to provide subsurface information in other areas • of the site not investigated with auger drilling and to establish a correlation (if possible) between the CPT and boring information. One of the CPT soundings (CPT-2) is located adjacent Boring B-2 . Location CPT-6A was investigated due to the practical equipment refusal encountered at location CPT-6 . The CPT locations were prepared by exposing the liner with hand excavation equipment. Approximately 4 inch square flaps were cut into the synthetic liner to allow the cone to advance below the liner. We understand that the liner is to be repaired and soil protective cover replaced by others. Test Pits TP-1 through TP-3 were excavated in the northeast portion of the site on April 30, 2004. The test pits were located in the area where structures were known to exist in the past. The excavations were conducted to observe the subsurface profile and to observe existing buried structures and foundations . Photographs of conditions encountered in Test Pits TP -1 through TP-3 are presented in Appendix IV. Test Pits TP-4 through TP-7 were excavated on June 15, 2004. Test Pits TP-4 and TP-5 were excavated along the west slope to observe the slope profile and the subsurface conditions below the fill embankment materials. Test Pits TP-6 and TP-7 were excavated along the southeast and northeast portions of the site, respectively, in the area of the proposed main roadway to extend through the proposed development. The test pits were backfilled without · significant compaction. The backfill in the test pits should be properly compacted where it will support proposed buildings, floor slabs or pavements. Logs of the s ubsurface conditions encountered in th e borings and t est pits are presented on Figures 7 through 10 with legend a nd notes on Figure 11 . The data obtained from the CPT investigation i s provided in Appendix I. Av~'\: APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 10401 94 Page 9 SUBSURFACE CONDITIONS Up to approximately 58 feet of tailings was encountered in the borings and cone penetration testing {CPT} investigations. The tailings encountered at the site vary in material characteristics, density and thickness. The tailings generally consist of areas of fine-grained and coarse grained materials. The fine-grained tailings were generally encountered in areas of tailings ponds and low areas across the site. Coarse tailings were encountered in areas of dikes and embankments which extend throughout the tailings area . Based on a review of aerial photographs of the tailings areas, we anticipate that the majority of the site contains fine grained tailings associated with the tailings ponds. Fill {non-tailings} was encountered in test pits excavated along the northeast portion of the site and along the west and south perimeter slopes of the site. The fill consists of clayey sand and sandy lean clay. Concrete structures and small to moderate amounts of debris, wood, organics and metal was encountered in the area of Test Pits TP-1 through TP-3. The natural soil encountered below the fill and tailings consists of lean clay, sand and gravel. Sand and gravel was encountered below the clay and extends the maximum depth investigated, approximately 72 feet. A description of the various soils encountered in the borings and test pits follows: Tailings Cap -The cap consists of soil protective cover overlying a synthetic liner system. The soil protective cover consists of lean clay and silt with small amounts of sand. It is slightly moist to moist, brown to grayish brown and contains roots and organics in the upper approximately ½ foot. The liner system consists of a geocomposite drain {textile and net} overlying a geomembrane overlying a geosynthetic clay liner. Av!:..'\: APPLIED GEO TECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 10 Tailings (Fine-Grained) -The fine-grained tailings consists primarily of clay and silt sized particles associated with the hydraulic disposal of the tailings at the site . The fine grained tailings have low to high plasticity and small to moderate amounts of sand. It is moist to very moist, brown to gray and dark gray and contains occasional organics. Laboratory tests conducted on samples of the fine-grained tailings indicate that it has moisture content ranging from 10 to 5 2 percent and dry densities ranging from 7 2 to 100 pounds per cubic foot (pcf). Results of consolidation tests performed on the fine-grained tailings indicate that it will compress a moderate to large amount with the addition of light to moderate loads . Results of the consolidation tests are presented on Figures 17 through 20. Laboratory tests were performed on samples of the fine-grained tailings to determine their strength characteristics. Direct shear tests conducted on samples of the tailings indicate an internal friction of 30 to 41 degrees and cohesion ranging from 60 to 1,400 pounds per square foot (psf). Results of the direct shear tests are presented on Figures 23, 24 and 27. An unconfined compressive strength of 640 psf was measured for a sample of the tailings tested. Results of a gradation and moisture/density relationship (Proctor) test conducted on a sample of the fine-grained tailings indicate that the material tested has a maximum dry density of 139.5 pcf and an optimum moisture content of 9.5 percent as determined by ASTM D-1 5 5 7 . Results of the gradation and Proctor tests are presented on Figure 14. Av~~ APPLIED GEO TECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 11 The fine-grained tailings are generally very soft to dense with moderate to high compressibility. Penetration resistance values obtained from the borings range from 2 to 4 7 blows per foot using a 140 pound hammer falling approximately 30 inches. Tailings (coarse) -The coarse tailings consist primarily of sand sized particles with low to moderate plasticity. It is moist to very moist, gray to orangish brown to brown. Laboratory tests conducted on samples of the coarse tailings indicate that it has moisture contents ranging from 4 to 34 percent and dry densities ranging from 86 to 116 pcf . Direct shear tests conducted on samples of the coarse tailings indicate internal friction ranging from 23 to 30 degrees and cohesion ranging from 50 to 5 70 psf. Results of the direct shear tests are presented on Figures 25 and 26. Results of a gradation and moisture/density relationship (Proctor) test indicate that the material tested has a maximum dry density of 126.0 pcf and an optimum moisture content of 10 percent as determined by ASTM D-1557 . Results of the gradation and Proctor tests are presented on Figure 1 3. The coarse tailings are generally loose to v ery dense and exhibit slight to moderate compressibility. Penetration resistance values obtained from the borings range from 7 to 71 blows per foot using a 140 pound hammer falling approximately 30 inches. Fill (non -taili ngs) -The non-tailing fill consists primarily of clayey sand and sandy l ea n clay with sma ll to moderate amounts of gravel. The fill contains occasional areas of debris, wood, organics and metal. The fill is slightly moist to moist and brown to grayish brown. Buried concrete structures and small to moderate amounts of debris, wood organics a nd metal were encountered in Test Pits TP-1 through TP-3 . Av~'\: APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 12 In-place moisture and density tests were conducted on portions of the fill encountered in Test Pits TP-1, TP-2 and TP-3. The results of field testing indicate that the materials tested vary in material type, density and amount of debris and organics. The results of the field moisture and density tests conducted with a nuclear density gauge indicate that the areas tested have dry densities ranging from 83 to 111 pct and have moisture contents ranging from 11 to 32 percent. The results indicate that the areas tested have been compacted to approximately 80 to 92 percent of the maximum dry density as determined by ASTM D-1557. The test results indicate that the moisture content of the areas tested is near or above the optimum moisture content. Embankment Material • The material sampled from the west side embankment consists of silty, clayey gravel with sand. A direct shear test was conducted on the portion of the sample which passed the No. 4 sieve and was remolded to approximately 90 percent of the maximum dry density as determined by ASTM D- 1557 and near the optimum moisture content. The results of the direct shear test are presented on Figure 28. The results of gradation and moisture/density relationship tests conducted on samples of the embankment material are presented on Figures 32 and 33. Clay· The clay contains small amounts of sand. It is soft to medium stiff, moist to wet, brown to gray and greenish gray and contains organics. Laboratory tests conducted on samples of the clay indicate that it has natural moisture contents ranging from 1 5 to 36 percent and natural dry densities ranging from 76 to 110 pct. Unconfined compressive strengths of 930 and 1,780 psi were measured for samples of the clay tested in the laboratory.

Results of the consolidation tests are presented on Figures 21 and 22. Clayey Sand -The clayey sand contains small to moderate amounts of clay. It is medium dense, slightly moist to moist and gray. Silty Sand -The silty sand contains small to moderate amounts of silt. It is medium dense, slightly moist and brown. Poorly Graded Sand -The sand contains small amounts of silt, occasional silty sand and gravel. The sand is dense to very dense, very moist to wet and gray to brown. Laboratory tests conducted on samples of the sand indicate that it has natural moisture contents ranging from 20 to 34 percent and a natural dry density of 83 pcf. Results of a gradation test conducted on a sample of the sand is presented on Figure 12. Poorly Graded Gravel -The gravel contains small to moderate amounts of sand. It is dense to very dense, wet and gray to brown. A summary of the laboratory test results is presented on Table I and is included on the logs of the exploratory borings and test pits, Figures 7 and 10. tWt~ m r t "tWffl4@ l®U , et e• Ml m Av~,;;; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 14 SUBSURFACE WATER / Subsurface water was encountered in Borings B-1 through B-4 at depths ranging from • approximately 49 ½ to 58 ½ feet below the existing ground surface. The subsurface water measured in May and July 2004 range from approximate elevation 4233 ½ to 4237 feet. Subsurface water was encountered in Test Pits TP-4 through TP-6 at depths ranging from approximately 9 to 14 ½ feet below the adjacent ground surface. The subsurface water measured in June and July 2004 ranges from approximate elevation 4229 ½ to 4230 ½ feet. Based on the CPT data, subsurface water was encountered at approximate elevation 4228 to 4241 feet. No subsurface water was encountered in Test Pits TP-1 through TP-3 and TP-7 at the time of excavation to the depth investigated. Slotted PVC pipe was installed in Borings B-2 through B-4 and Test Pits TP-4 through TP-6 to facilitate future measurement of the water level. Fluctuations in the water level will occur with time. An evaluation of such fluctuations is beyond the scope of this report. Generally, water le vels are expected to be highest in the spring and summer and lowest in the fall and winter months. The subsurface water level at the site ranges from approximate elevation 4228 to 4241 feet. The measured water levels appear to be below the fill or tailings/natural soil interface. While some of the fill and tailings have relatively high moisture contents, we do not have evidence that the subsurface water level extends up into the tailings. The subsurface water elevations are generally higher along the eastern portion of the site with gradually lower elevations to the west and the Jordan River. We anticipate that the su sur.face water flow is downward to the west.

Av£'\: APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 16 PRELOAD MONITORING The time rate of settlement at four preload areas are being measured by others. The approximate preload locations are presented on Figures 1 and 2. Two of the areas (Areas B-1 and B-2) are located where significant amounts of relatively soft, compressible tailings were encountered . The third area (Area CPT-3) is an area of less compressible subsurface conditions (generally coarse tailings and granular material with higher in-place densities). The third and fourth areas (Areas CPT-3 and B-4) are adjacent the 3 horizontal to 1 vertical side slopes. Approximately 1 5 feet of preload fill was placed in an area approximately 50 to 70 feet square at the 4-areas indicated above. The fill was imported to the site and placed without significant compaction. Samples of the fill were obtained for laboratory classification testing. The results of gradation tests conducted on samples of the fill are presented on Figures 29 and 30. In-place moisture and density tests were conducted on top of each fill pile with a nuclear density gauge. The test results indicate that the areas tested have dry densities ranging from 62 to 120 pcf and moisture contents ranging from 10 to 38 percent. Results of gradation and moisture/density relationship (Proctor) tests conducted on a sample of the preload material are presented on Figure 31. Settlement plates were established in the monitoring areas and measured by others. The settlement data was provided to AGEC for evaluation. The settlement monitoring has been conducted for a relatively short period of time (up to approximately 21 0 days through December 6, 2004). Based on the available data, approximately 8 to 15 ½ inches (average of 10.3 inches) of settlement has been measured in the compressible tailings areas. Approximately 2 to 5 ½ inches (average of 3.1 inches) of settlement has been measured in the areas with less compressible material and adjacent the slopes. Plots of the measured settlement and length of time for each of the areas monitored are presented in Appendix II. Av~'\; APPLIED GEOTECHNICAL ENGINEE RING CONSULTANTS, P.C. 10401 94 Page 17 We anticipate that the primary settlement of the coarse grained tailings will occur rather quickly, likely during fill placement. The settlement monitoring data indicates that the primary settlement of the fine grained tailings continues. PROPOSED CONSTRUCTION We understand that the proposed development is planned to be a mixed land use community which may include commercial office/business park and a variety of residential uses. We anticipate that the proposed structures will range from one to two-story, wood-frame residences with a possibility of basements to multi-story, wood-frame masonry and steel frame commercial and office buildings. We understand that the building foundations are planned to extend below grade and will likely remain above the existing tailings liner. We anticipate that foundations may extend to within approximately 1 foot of the existing liner system. We have assumed building loads to consist of wall loads of less than 5 kips per lineal foot and column loads of less than 100 kips based on typical construction in the area. Specifically, we have assumed exterior column loads of up to 50 kips and interior column loads of up to 100 kips. We understand that consideration is being given to constructing several buildings near or along the slope which extends along the north, south and west sides of the site. We understand that foundations for structures near and along the slopes may extend below the liner system. The geotechnical engineer should review project plans (including building location, size, type of construction, building loads, foundation system, site grading plans and slope stability) for conformance to the recommendations presented in the report. Roadways and parking areas are planned to extend throughout the proposed development. Jordan Bluffs Parkway is planned to be the main access through the project. Anothe r roadway is planned to be constructed along an embankment to extend south from the Av~'\: APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 18 southeast portion of the cap and tie into 700 West Street which extends along the east side of the site. We have assumed and our pavement recommendations are based on traffic for residential areas consisting of 1000 cars and 2 delivery trucks per day and 2 garbage trucks and 5 buses per week. Thicker pavement sections are anticipated for collector and major roadways planned for the development. We anticipate that open space and landscape areas will extend through the development. If the proposed construction, building loads or anticipated traffic is significantly different from what is described above, we shou ld be notified to reevaluate the recommendations given. SLOPE STABILITY A slope stability analysis was conducted u sing static and pseudo-static (seismic) analyses. The seism ic analysis was performed u sing a peak horizontal ground acceleration of 0. 1 29g representing a 10 percent probability of exceedance in 50 years which represents a return period of 475 years. The peak horizontal ground acceleration was reduced based on the State of California, Division of Mines and Geology Special Publication 11 7, "Guidelines for Analyzing and Mitigating Landslide Hazards in California" (Southern California Earthquake Center, 2002), assuming an allowable 10 centimeters of displacement. The stability ana lysis was conducted on a profile cons isting of a 3 horizontal to 1 vertical slope with a maximum height of 70 feet. The existing slopes have slopes up to approximately 45 feet high. The strength parameters for the embankment materials were based on the results of l aboratory tests and our experi ence in the area. The strength parameters used in the analysis consi st of 34 degrees friction and 100 psf cohesion. It is our professional opinion Av~"\: APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 19 that the embankment material likely has strengths equal to or greater than the strengths used in the stability analysis. Based on the ground surface profile, the material strengths used in the analysis and the subsurface conditions, the stability analysis indicates safety factors greater than 1.5 and 1 .0 for static and seismic conditions, respectively. Additional stability analysis was conducted on the perimeter side slopes assuming that approximately 5 feet of material just above the tailings/natural soil interface liquefies during a seismic event. We have assumed that if liquefaction were to occur, the liquefiable zone would extend laterally across the tailings pond areas. Strength parameters for the embankment and site grading fill material used in the analysis consist of 34 degrees friction and 100 psf cohesion. Strength parameters used for the tailings consists of 30 degrees friction and 200 psf cohesion. In reviewing tailing properties across the site, approximately 65 percent of the material would liquefy with an acceleration of at least 0.25g which represents a seismic event with a 10 percent probability of exceeda nce in 50 years. The analysis indicates that a seismic safety factor of 1 .0, assuming that approximately 65 percent of the material within the 5 foot zone liquefies during a se ismic event with a 10 percent probability of exceedance in a 50 year time period. A slope stability safety factor on the order of 1.5 under static conditions is typically acceptable for long term conditions for a slope n ear structures. Under seismic conditions, a safety factor of 1.0 is considered suitable for the deformation indicated. Av/:..'\;' APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 20 PRELIMINARY DESIGN AND SITE GRADING RECOMMENDATIONS The following recommendations are given for conceptual/preliminary design and site grading at the site. The recommendations should be reviewed and implemented with consideration given to the expectation of performance and risk tolerance of the end-users/individual owners . Typically, home owners have significantly higher performance expectations than that of commercial owner/tenants . Thus, the direction taken during development should be tailored for the end-users/individual owners. For example: If a portion of the fill and existing buried structures are left below proposed floor slab areas, we recommend that at least 3 feet of properly compacted fill be provided below the proposed floor slab area . Due to the higher expectations of resid ential owners, consideration should be given to providing a thicker layer of properly compacted fill below the proposed floor slab area. Based on the subsurface conditions encountered, the laboratory test results, our understanding of the proposed construction and our experience in the area, the following preliminary design and site grading recommendations are given: A. Existing Tailings Up to approximately 58 feet of tailings was encountered during the investigation. The tailings generally consist of fine-grained and coarse materials. The fine-grained t ai lings were generally encountered in areas of tailings ponds and low areas across the site. Coarse tailings were encountered in areas of dikes and embankments which extend throughout the tailings area. Based on a review of aerial photographs of the tailings areas, we anticipate that the majority of the site contains fine grained and/or compressible tailings associated with the tailings ponds . The fine-grained tailings are generally very soft to dense with moderate to high compressibility. The coa rs e t ailings are generally loose to very dense and exhibit slight to moderate compre ss ibility. Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 10401 94 Page 21 It is our professional opinion that, if the recommendations presented within the report are implemented during the design, site grading and construction phases of the project, the site may be considered suitable for the proposed construction. B. Site Grading Based on available site grading plans, we anticipate that the eastern portion of the site is to be raised approximately 5 feet above the existing ground surface while the -1 ridges and valleys of the cap along the west side of th·~-site are planned to recei-.t.e up to approximately 1 5 feet of fill. We anticipate that the existing 3 horizontal to 1 vertical slopes will continue upward as the site is raised. Fill placed for the project over relatively large areas should be placed as soon as possible prior to building construction. The settlement due to the site grading fill should be monitored to determine when the significant portion of the settlement has occurred and when building construction may begin. Surcharging the site by temporarily increasing the amount of fill placed over an area will reduce the preload time. Generally, doubling or tripling the amount of fill placed above the compressible tailings will reduce the preload time on the order of 50 to 75 percent. Based on the results of our analysis and the preload monitoring data, we anticipate significant amounts of primary (short term) settlement due to the compression of the fine grained compressible tailings under the increased load from the site grading fill. Figure 5 presents graphically the estimated short term settlement of the compressible tailings for various thicknesses of site grading fill. We anticipate that up to approximately 20 inches of settlement may result from approximately 1 5 feet of site r grading fill placed above the more compressible tailings. Smaller amounts of settlement are anticipated in areas of less tailings and areas with increased amounts of granular tailings. The estimated time for the primary settlement due to the weight of the site grading fill to occur was based on the results of laboratory testing and our engineering Av~'\: APPLIED GEO TECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 22 analysis. Figure 6 presents the estimated time for the settlement due to the site grading fill to occur. The lines on the graph represent the estimated time after which approximately 1 and 2 inches of short term settlement remain. For approximately 15 feet of site grading fill, we estimate that up to approximately 19 months will be " needed for the primary portion with less than 1 inch of remaining settlement of the settlement to occur. Secondary (long term) settlement is estimated to be on the order of 1 and 1 .. ½ inches over the next 15 and 30 years, respectively . This settlement should be considered differential with respect to areas of the site with significantly less compressible tailings. With the exception of areas of significant, distinct changes i n subgrade conditions, we anticipate that the estimated secondary settlement will generally occur uniformly over large areas. The estimated secondary settlement may be reduced and considered negligible in areas where at least 2 feet of additional preload fill is placed. This fill is placed in addition to the site grading fill and surcharge placed to accelerate the time for primary settlement to occur. Placing fill in addition to the proposed site grading fill (surcharge) will accelerate the time for short term settlement to occur. Generally, doubling the height of the fill will halve the estimated time for settlement. The following table summarizes the fill amounts and reduction time for primary settlement to occur. Total Fill Estimated Time For Site Grading Fill Surcharge Fill Placement Settlement to Occur 5 feet none 5 feet T 5 feet 10 feet ½T 10 feet 15 feet ¼T 15 feet none 15 feet T 15 feet 30 feet ½T Note: "T" represents the estimat ed time from Figure 6 . Av/:.,.":;;;" APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 23 Based on the information presented above, doubling the fill placement in areas to receive 15 feet of site grading fill could reduce the time for settlement to occur from up to· ,19 months t<;> approximately 9 ½ months. Tripling the fill placement in areas to receive approximately 8 ½ feet of site grading fill (average fill for the project) could reduce the time for settlement to occur from up to 17 months to approximately 4½ months. Settlement monitoring should be conducted to determine when the significant portion of the settlement has occurred and when construction of settlement sensitive structures may begin. More detailed recommendations for fill placement and monitoring can be developed with increased understanding of the behavior of the compressible tailings at the site. Due to the highly compressible nature of the fine grained tailings and material placed within the tailings ponds at the site, building pad areas, within the shaded area indicated on Figure 4, should be preloaded with soil equal in weight to the anticipated change in stress due to site grading fill and proposed structures . The following loading conditions were evaluated: interior column loads of 100 kips, exterior column loads of 50 kips and interior/exterior column loads at a basement level. The following table summarizes the amount of preload to reduce post construction settlement for the bearing pressures and loading conditions indicated. The preload thickness is measured from the adjacent final grade elevation . Preload Foundations Bearing Level Bearing Pressures (D epth Below Type and Load Final Grade) 1,500 psf 2,000 psf 2,500 psf Interior (100 kip s) 1 ' 6' 8' 1 0' Exterior (50 kips) 2 ' 6' 6' 8' Basement Interior ( 100 kips) 6' 8 ' 10' 17' Basement Exterior (50 kips) 6' 11' 15' 19' Note: Unit weight of preload is 110 pct (assumed). Avl=,.."\;' APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 10401 9 4 Page 24 Due to the highly compressible nature of the tailings, the preload thickness increases significantly as the foundation bearing elevation approaches the tailings. The preload thickness may be reduced if at least 3 feet of structural fill is provided between the foundation and the tailings. The preload thicknesses can be refined when actual building loads and bearing e levations have been established. 1 . Excavation 2. We anticipate that excavation at the site can be accomplished with typical excavation equipment. Care should be taken to minimize disturbance of the suitable material which remain below the proposed building areas. Pavement Subgrade Preparation We anticipate that pavements may be constructed above areas of undisturbed natural soil, areas of existing structures, fill (possibly containing debris) and areas of existing capped tailings. The following summarizes pavement subgrade preparations for each of these areas. a. Natural Soil b. Pavement subgrade areas consisting of undisturbed natural soil shou ld not be scarified but cut to undisturbed natural soil below the topsoil, organics or other deleterious material and a sufficient thickness of granular fill placed to allow for adequate compaction and access for construction traffic . Existing Structures and Fill Ideally, pavement subgrade areas would be free of topsoil, organics, unsuitable fill, buried structures, debris, and other deleterious materials. We anticipate that some of the existing structures and fill may extend to significant depths below the proposed pavement surface. If the owner is willing to accept the risk of potential pavement distress due to differential densification of the existing fill, Avl:.a,~ APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 25 consideration may be given to leaving a portion of the existing fill and buried structures below proposed pavement areas. If a portion of the existing fill and buried structures are left below proposed pavement areas, we recommend that at least 3 feet of properly compacted fill be provided below the pavement section. The subgrade should be proof rolled prior to placement of fill or base course to identify soft areas. Soft areas should be removed and replaced with properly compacted fill. c. Tailings Areas Roadways are planned to extend above the capped tailings and liner system. We anticipate that placement of the site grading fill may help reduce the impact of differential densification of the tailings. The tailings area subgrade should be free of vegetation, organics, debris and other deleterious material. The subgrade should be proof rolled prior to placement of fill or base course to identify soft areas. Soft areas should be removed and replaced with properly compacted structural fill. 3. Wet Subgrade We anticipate that the upper portion of the natural soil, site grading fill and the tailings soil protective cover material may consist of clay and silt which may result in construction access difficulties for rubber-tired construction equipment when the fine-grained soil is very moist to wet such as in the winter or spring or in times of prolonged rainfall. Placement of gravel with less than 15 percent passing the No. 200 sieve will generally improve site access for construction. Generally, 1 to 2 feet of granular fill will provide limited support for moderately loaded rubber-tired construction equipment above a very moist to wet clay/silt subgrade. rem -n@r w~n ;w 2 J. iW M Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 4. 5. ffh&iikihM 52# Page 26 Soil Protective Cover The soil protective cover should be properly prepared prior to receiving site grading fill. The soil protective cover should be cleared of vegetation, organics and other deleterious material. The cover material should be moisture conditioned to near or slightly above the optimum moisture content and densified with compaction equipment. Care should be taken to avoid damage to the liner system during reconditioning of the cover material and placement of site grading fill. Compaction Compaction of materials placed at the site should equal or exceed the minimum densities as indicated below when compared to the maximum dry density as determined by ASTM D-1557 (Modified Proctor) and ASTM D-698 (Standard Proctor). Fill To Support ASTM D-1557 Foundations ~ 95% Concrete Slabs and Pavement ~ 90% Landscaping ~ 85% Retaining Wall Backfill 85 -90% ASTM D-698 ~ 100% ~ 95% ~ 90% 90 -95% Base course should be compacted to at least 95 and 100 percent of the maximum dry density as determined by ASTM D-1557 and ASTM D-698, respectively. To facilitate the compaction process, fill should be compacted at a moisture content within 2 percent of the optimum moisture content. The fill should be placed and compacted in thin enough lifts to allow for proper compaction. r mi&MMWit&i @W@fi • M t nU h ±MOO Av~,;;;; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 6. !Sffii Page 27 Fill and pavement materials placed for the project should be frequently tested for compaction. Due to the significant amount of fill, uncertainty of fill sources and types of fill planned to be placed at the site, we recommend full- time testing and observation during fill placement. Materials Listed below are materials recommended for imported structural fill. Fill to Support Footings Floor Slab (Upper 4 inches) Slab Support Recommendations Non-expansive granular soil Passing No. 200 Sieve < 35% Liquid Limit < 30% Maximum size 4 inches Sand and/or Gravel Passing No. 200 Sieve < 5% Maximum size 2 inches Non-expansive granular soil Passing No. 200 Sieve < 50% Liquid Limit < 30% Maximum size 6 inches Generally, the on-site soil and existing fill do not meet the material recommendations presented above for fill placed to support structures but may be used in pavement areas or as utility trench backfill if the topsoil, organics, debris and other deleterious materials are removed or they may be- used in landscaping areas. Consideration may be given to using recycled concrete as fill for the project. The recycled concrete should be free of debris and other deleterious materials and be processed or crushed to a gradation suitable to allow for proper placement and densification. Care should be taken to avoid nesting of larger particles during fill placement. 1 tt Q J EM Fl"1IIWI" Av£"\: APPLIED GEOTECIINICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 28 Based on the significant thickness of site grading fill to be placed at the site to facilitate development, consideration may be given to using other available fill materials free of debris, organics, over-sized particles and other deleterious materials as fill for the project. Material suitability may be addressed as the material becomes available. Increased placement and compaction difficulties can be expected when using fill with greater amounts of fine grained material. Care will be required to properly moisture condition the material prior to compaction. Ideally, the fill would be compacted at a moisture content near or slightly above the optimum moisture content. Fill placed at the site may require moisture conditioning (wetting or drying) prior to use as fill or backfill. Drying of the soil may not be practical during cold or wet times of the year. Excavation in the lower areas of the site adjacent the west and south sides of the capped tailings area may extend below the free water level. Free- draining gravel with less than 5 percent passing the No. 200 sieve should be used as structural fill where excavations extend below the free-water level. 7. Drainage The ground surface surrounding the proposed structures should be sloped away from the buildings in all directions. Roof down spouts and drains should discharge well beyond the limits of backfill. The collection and diversion of drainage away from the pavement surface is important to the satisfactory performance of the pavement. Proper drainage should be provided. ?¥¥65§4 t¥& ] ;;;;;;; Av£°\; APPLIED GEO TECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 29 C. Slopes Modification of the existing slopes (excavation near the toe of the slope or placement of fill along the upper portion of the slope) could result in reduced slope stability. The geotechnical engineer should review project plans relating to construction near and along slopes for conformance to the recommendations presented in the report. D. Foundations z A discussion of the proposed construction including building construction and loads are presented in the Proposed Construction section of the report. If the proposed construction or building loads are found to be significantly different from those described, the geotechnical engineer should be notified and additional evaluation may be needed. 1 . Tailing Subgrade Preparation 2. Proposed structures may be supported on spread footings bearing on the existing tailing areas which are preloaded, monitored for settlement and determined that the significant portion of settlement has occurred prior to building construction (prepared tailings subgrade). Bearing Material With the proposed construction and the subsurface conditions encountered, the proposed structures may be supported on spread footings bearing on the undisturbed natural soil, compacted structural fill extending down to the undisturbed natural soil, or above the prepared tailing areas. Deep foundation systems may also be considered for the project. The following summarizes foundation support above existing structures and fill and above the capped tailings. 1H ~ AV~'\; APPLIED GEOTECEINICAL ENGINEERING CONSULTANTS, P.C. 1040194 i a. b. Page 30 Existing Structures and Fill Areas Existing concrete structures consisting of foundations, columns and floor slabs were encountered along the northeast portion of the site. Fill was observed adjacent the structures in the test pits excavated in the area. Ideally, the existing buried structures, unsuitable fill (non- tailings), debris and other deleterious material would be removed from below proposed building areas. Structural fill placed below foundations should extend down to the undisturbed natural soil or prepared subgrade consisting of existing fill suitable for building construction and out away from the edge of the footings a distance equal to the depth of fill placement beneath the footings. We understand that consideration is being given to leaving the existing structures and fill below the proposed building areas. If the owner is willing to accept the risk of potential building distress due to differential densification of the existing fill, consideration may be given to leaving a portion of the fill and existing structures below the proposed building areas. If the existing fill and structures or a portion . of the existing fill is left below the proposed building areas, we recommend that at least 5 feet of properly compacted structural fill be provided below the foundation bearing elevation throughout the entire footprint of the proposed structure. Consideration may be given to constructing a "crushed zone", which consists of a layer of crushed stone, rock or concrete as structural fill. The crushed zone should be at least 5 feet thick overlying any existing fill or structures. Tailing Areas Spread footings may also be constructed above the existing tailing areas that have been properly prepared. Foundations may extend to within 1 foot of the existing liner system. ~ h f & i i! WmNittM kPii &.lZ& %i Av~"\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 3. Page 31 Care should be taken to avoid having portions of the proposed building foundation above significantly different bearing materialp (such as partially above natural lean clay and partially above structural fill or tailings). Additional excavation and fill placement may be needed to provide a more uniform foundation support. Bearing Pressures a. Natural Soil Areas b . The proposed structures may be supported on spread footings bearing on the undisturbed natural soil or on compacted structural fill extending down to the undisturbed natural soil. Foundations bearing on the undisturbed natural lean clay may be designed using an allowable net bearing pressure of 1,500 psf. Footings bearing on at least 1 and 2 feet of properly compacted structural fill extending down to the undisturbed natural soil may be designed using an allowable net bearing pressures of 2,000 and 2,500 psf, respectively. Higher bearing pressures may be provided for greater thickness of structural ' fill and granular bearing materials. Footings should have a miri_imum width of 18 inches and a minimum depth of embedment of 10 inches. Existing Structures and Fill Areas As described above, 5 feet of compacted structural fill is recommended below the foundation bearing elevation in areas where the existing structures and fill or a portion of the fill is left below proposed structures. Foundations bearing on at least 5 feet of properly compacted fill may be designed using an allowable net bearing pressure of 2,500 psf . • Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 32 c. Tailing Areas Foundations bearing on at least 1 foot of compacted structural fill above th_e liner system in capped tailings areas may be designed using an allowable net bearing pressure of 1,500 psf. Footings bearing on at least 2 and 3 feet of properly compacted structural fill extending down to "prepared tailings subgrade" may be designed using an allowable net bearing pressures of 2,000 and 2,500 psf, respectively. This assumes that the sign ificant portion of the settlement due to the site grading and structural fill has occurred prior to building construction. 4 . Temporary Loading Conditions The allowable bearing pressure may be increased by one-half for temporary load ing conditions such as wind or seismic loads. 5. Settlement 6. We estimate that total and differential settlement due to the load imposed by the proposed structures only will be less than 1 inch and ¾ inch, respectively, for footings designed and constructed as indi cated above . Disturbance of the soil below the foundation bearing elevation can result in greater settlement . Care should be taken not to disturb the soil to remain below the proposed foundation area. Frost Depth Exterior footings and footings beneath unheated areas should be pla ced at least 30 inches below grade for frost protection. Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 7. Page 33 Foundation Base The base of footing excavations should be cleared of loose or deleterious material prior to structural fill or concrete placement or footings should extend to adequate bearing material. 8. Construction Observation A representative of the geotechnical engineer should observe footing excavations prior to structural fill or concrete placement. E. Concrete Slab-on-Grade 1 . Slab Support # a. Natural Soil Areas Concrete floor slabs may be supported on the undisturbed natural soil or on compacted structural fill extending down to the undisturbed natural soil. b. Existing Structures and Fill Areas " Ideally, existing buried structures, unsuitable fill, debris and other deleterious materials would be removed from below proposed floor slab areas. However, if the owner is willing to accept the risk of potential floor slab distress due to differential densification of the existing fill, consideration may be given to leaving a portion of the fill and existing structures below the proposed floor slab areas. If the existing fill and structures or a portion of the existing fill is left below the proposed floor slab areas, we recommend that at least 3 feet (5 feet for residential construction) of properly compacted structural fill be provided below the entire footprint of the proposed building. i& t ¼&44 & fo~iUJJ&Jim.4.: ! ii wt 5rffl :Caffi Av'~'\; APPLIED GEOTECIINICAL ENGINEERING CONSULTANTS, P.C. 1040194 2. c. Page 34 Tailing Areas Concrete slabs may be constructed on properly compacted fill extending down to a "prepared tailings subgrade". Underslab Sand and/or Gravel A 4-inch layer of free-draining sand and/or gravel (less than 5 percent passing the No. 200 sieve) should be placed below the concrete slabs for ease of construction and to promote even curing of the slab concrete. 3. Vapor Barrier A vapor barrier should be placed below the underslab sand and/or gravel if the floor will receive an impermeable floor covering. The barrier will reduce the potential for water vapor passing from below the slab to the floor covering. F. Lateral Earth Pressures 1 . Lateral Resistance for Footings Lateral resistance for spread footings placed on the undisturbed natural soil, on compacted structural fill or on structural fill placed above the tailings is controlled by sliding resistance between the footing and the foundation soils. A friction value of 0.35 may be used in design for ultimate lateral resistance. 2. Subgrade Walls and Retaining Structures The following equivalent fluid weights are given for design of subgrade walls and retaining structures. The active condition is where the wall moves away from the soil. The passive condition is where the wall moves into the soil and the at-rest condition is where the wall does not move. The values listed below assume a horizontal surface adjacent the top and bottom of the wall. t 44HWffffl:rt5t Avb'\:' APPLIED GEOTECHNICAL ENGINEERING coNsULTANTs, P.c. 1040194 Soil Type Clay & Silt Sand & Gravel Active 50 pcf 40 pcf At-Rest 65 pcf 55 pcf Passive 250 pcf 300 pcf Page 35 3. Seismic Conditions 4. Under seismic conditions, the equivalent fluid weight should be increased by 31 pcf for active and at-rest conditions and decreased by 31 pcf for the passive condition. This assumes a short period spectral response acceleration of 1.34g which represents a 2 percent probability of exceedance in a 50-year period which represents a return period of 2,475 years (IBC, 2000 and 2003). Safety Factors The values recommended above assume mobilization of the soil to achieve soil strength. Conventional safety factors used for structural analysis for such items as overturning and sliding resistance should be used in design. G. Seismicity, Faulting and Liquefaction 1 . 2.

Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 3. @Ai Page 36 Liquefaction The site is located in an area mapped as having a "high" liquefaction potential (Salt Lake County, 1995). The soil type most susceptible to liquefaction during a large magnitude earthquake is loose, clean sand. The liquefaction potential for soil tends to decrease with an increase in fines content and density. A site-specific evaluation of the liquefaction potential was conducted in conjunction with this study. The subsurface soil encountered at the site consists of up to approximately 56 feet of tailings overlying natural lean clay and relatively dense sand. Subsurface water was encountered at depths of approximately 49 ½ to 58 ½ feet below the existing ground surface in the area of the tailings and at depths ranging from 9 to 14 ½ feet below the existing ground surface in areas excavated along the west and south sides of the site. Clay and soil above the free-water level are not considered susceptible to liquefaction. Three conditions were evaluated as part of this study. The first condition evaluates the liquefaction potential of the natural soil below the measured water levels. The second condition evaluates the natural soil below the measured water levels along with granular tailings above the water level which are saturated or near saturation. The third condition evaluates the natural soil and granular tailings below the water level should the water level rise approximately 5 feet above the water levels measured at the time of our investigation. a. Condition 1 The natural sand encountered below the free-water level is relatively dense. Based on our liquefaction analysis at the site, the natural sand below the free-water level has a "very low" liquefaction potential. ~-£ ic' f® 2 i¼P¾&AM@t±&H@ 4i44M W Av£°\; APPLIED GEOTECIINICAL ENGINEERING CONSULTANTS, P.C. 1040194 b. Page 37 Less than 1 inch of settlement is expected during a seismic event with a 1 0 percent probability of exceedance in 50 years which represents a return period of 4 75 years. Condition 2 Assumes that the water level remains near the level measured at the time of this investigation and that some of the coarse grained tailings above the water level are saturated or near saturation. The analysis indicates that the saturated or near saturated granular tailings (sand) are susceptible to liquefaction. Settlement on the order of 2 ½ inches or less is expected during a seismic event with a 10 percent probability of exceedance in 50 years which represents a return period of 475 years. c. Condition 3 This condition assumes that the subsurface water level rises approximately 5 feet above the water levels measured at the time of our investigation. At these assumed water levels, the water would likely extend into the lower portion of the tailings. The analysis indicates that the granular tailings (sand) below the assumed water levels has a "moderate" to "high" liquefaction potential. Settlement on the order of 2 ½ inches or less is expected during a seismic event with a 10 percent probability of exceedance in 50 years assuming a 5-foot rise in water level. The likelihood of significantly higher water levels and a seismic event sufficient to cause liquefaction occurring at the same time is very small. Consideration may be given to additional study of water well histories in the area to better define past fluctuations in water levels, Av£'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 38 duration of higher water levels and probabilities of high water along with seismic events. The results of our liquefaction evaluation are presented in Appendix Ill. H. Water Soluble Sulfates Two samples of the tailings were tested in the laboratory for water soluble sulfate content. Test results indicate that the sample obtained from Boring 8-2 at a depth of approximately 4 feet contains 6,000 parts per million water soluble sulfate. The test results indicate that the sample obtained from Boring B-3 at a depth of approximately 2 feet contains 370 parts per million water soluble sulfate. Based on the results of the tests and published literature, portions of the tailings possess severe sulfate attack potential on concrete. Sulfate resistant cement is recommended for concrete placed in contact with the existing tailings. Consideration may also be given to evaluating the sulfate attack potential of other fill material imported to the site which may be placed in contact with concrete. Other conditions may dictate the type of cement to be used for the project. I. Pavement Based on subsurface conditions encountered, laboratory test results and the assume traffic as described in the proposed construction section of the report, the following pavement support recommendations are given: 1 . Pavement Support We anticipate that the subgrade soils will likely consist of natural lean clay or site grading fill (granular soil). A California Bearing Ratio (CBR) of 3 percent was used in the analysis which assumes a clay subgrade. ii.ii !WTI ill& ¥1/¥t¥fi&4¥~fi ft¥wf M5f¥t:t 5 ¼A Av£'\;' APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 2. 3.

A flexible pavement section consisting of 3 inches of asphaltic concrete overlying 8 inches of base course is calculated. The base course thickness may be reduced to 6 inches where at least 6 inches of granular borrow is provided or in areas of reduced traffic or no bus and truck traffic such as cul de sacs. Granular fill may be needed to facilitate construction of the pavement when the upper soil consists of very moist to wet fine-grained soil as discussed in the Pavement Subgrade Preparation section of the report. Pavement Materials and Construction The pavement materials should meet the material specifications for the appropriate jurisdiction. Other materials may be considered for use in the pavement section. The use of other materials may result in the need for different pavement material thicknesses. /mi\~ j Av~'\; APPLIED GEOTECHNICAL ENGINEERING CONSULTANTS, P.C. 1040194 Page 40 LIMITATIONS This report has been prepared in accordance with generally accepted soil and foundation engineering practices in the area for the use of the client for design purposes. The conclusions and recommendations included within the report are based on the information obtained from the subsurface investigation conducted at the approximate locations indicated on the site plan and the data obtained from the laboratory testing. Variations in the subsurface conditions may not become evident until additional exploration or excavation is conducted. If the proposed construction, subsurface conditions or subsurface water level are found to be significantly different from those described above, we should be notified to reevaluate our recommendations.

The borings were drilled on April 27, 29 and 30, 2004 with 8-inch diameter hollowstem auger. The test pits TP-1, TP-2 and TP-3 were excavated on April 30, 2004 and test pits TP-4 through TP-7 were eXcavated on June 15, 2004 with tracked excavation equipment. Cone Pentration Testing (CPT) was conducted on May 1 3, 2004. locations of t_he test pits and CPT-5 were measured approximately by pacing from features shown on the site plan provided. locations of borings and CPT soundings were determined by survey. Elevations of the borings and test pits were determined by interpolating between contours shown on the site plan provided. The boring and test pit locations and elevations should be c'onsidered accurate only to the degree implied by the method used, The lines between the materials shown on the boring and test pit !ogs represent the approximate boundaries between material types and the transitions may be gradual.

Enclosed is one set of standard CPT plots, pore pressure dissipation plots apd a data diskette. The diskette contains data files for the CPT plots (*.cor files), the files for the PPD plots (*.ppd files). The "cor" and "ppd" files are text files that can be viewed with any text editor or imported into various programs, such as a spreadsheet. In addition to the data files, we have included the CPT plot files (*.djz files) and a DOS based print routine to reprint any of the CPT plots. See the readme file for printing instructions. The following table summarizes the work performed at the site.
