The purpose of our investigation was to explore the site, investigate subsurface soil conditions, and to provide design recommendations for the preparation of the proposed development. This report represents the results of our work. 1.2 Scope The scope of our work included: a field exploration consisting of four Test Pits, testing and analysis of soil samples obtained from Test Pits 1 thru 4, and the preparation of a report containing our findings and recommendations. 1.3 Attachments _ This report contains Site and Test Pit Location Plans, Profile Logs for Test Pits 1 thru 4, and our Laboratory Test Data Sheets (including Atterburg Limits & Gradations). See Figures and Appendices. 2.0 FINDINGS 2.1 Site Description The development site is located at 2684 Highway 32, between Indigo Lane and Regent Lane in Chico, California, and is 1.75 acres in size (see Figure 1). The site is bordered by developed land on the north, south and west sides, and by railroad tracks and orchards on the east sides. The proposed development for the site is for commercial metal buildings. On the date of our visit, 28 February 2008, the build sites had previously been cleared of trees and leveled. The site is mostly farmland and is rectangular in shape. 2.2 Subsurface Soil Conditions _ With a backhoe, excavations were made to depths of one and a half to seven and a half feet, as seen in Test Pit Logs 1 thru 4. It was determined that the test pits were of sufficient depth to represent the soil profile of the site. All excavations revealed relatively consistent _ subsurface soil for the site. The surface soils are predominately ML -sandy silt. After the test pits were dug and soil samples taken, the holes were filled with excavated material. The backfill materials in the holes were not properly compacted to any standard specifications. \\0tto\C\Work\2008\007-C1ean Rite Soils\report.doc page 1 Clean-Rite/Build-Rite March 24, 2008 2.3 Ground Water Groundwater evidence was not discovered in the test pits at the time of our exploration. Perched water was not encountered. 3.0 CONCLUSIONS AND RECOMMENDATIONS At the time that this report is being prepared, it is our understanding that the proposed construction at this site consists of lightweight commercial construction with slab -on -grade foundations. The recommendations contained in this report are based upon these assumptions. Prior to commencement of earthwork of the site a pre -construction meeting will be required in order to ensure that the recommendations included in this report are conveyed and performed in the manner in which they were intended. A representative of our office, the builder, the general engineer, the structural engineer and/or architect, and the governing jurisdiction should all be in attendance. A minimum of 72 hours notice will be required to coordinate scheduling. 3.1 Site Clearing Prior to site grading, all trees, surface weeds, expansive clays, and organics should be removed from the construction areas. The soil portion of this material can either be removed or stockpiled for. later use in landscape areas. After clearing has been completed, a representative of our office shall inspect the site to verify that all vegetation and loose debris have been removed prior to the commencement of construction. The extent of soil removal may vary depending upon the findings of this. subsequent inspection. Loose soils may be exposed after scarification requiring further removal. 3.2 Site Preparation Tree roots larger than one inch in diameter within five feet of the building pads or within driveways or roadways shall be removed, over excavated and replaced with properly compacted engineered fill. Any existing septic and water systems shall be removed, over excavated and replaced with properly compacted engineered fill. The finished pads may vary from the scarified depth. Building pads are to bear on a minimum of 24 inches of non - expansive, compacted soil. Fills shall be compacted in accordance with the procedures described in the following paragraphs. Prior to placement of engineered fill within the pad areas, all tree stumps and roots shall be removed and replaced with compacted engineered fill. , The exposed sub -grades should be moisture conditioned and compacted to a minimum of 90% relative compaction, based on test method ASTM D1557. Engineered fill should be placed in 8" loose lifts, moisture conditioned and compacted to 90% relative compaction. The compacted thickness of each layer shall not exceed 6 inches. Compaction control and testing should be performed by a qualified testing agency to insure the recommendations of this report are followed. Depending on the amount of rock encountered in the on-site or import soils. We recommend \\Otto\C\Work\2008\007-Clean Rite Soils\report.doc page 2 Clean-Rite/Build-Rite March 24, 2008 that compaction testing be performed using Sand Cone methods (per ASTM D1556), or Nuclear Density methods (per ASTM D2922). Prior to placement of engineered fill.within roadways, all tree stumps and roots shall be removed and replaced with compacted engineered fill. The exposed sub -grades should be moisture conditioned and compacted to a minimum of 95% relative compaction, based on test method ASTM D1557. Engineered fill and' road base should be placed in 8" loose lifts, moisture conditioned and compacted to 95% relative compaction. We also recommend that the road sub -grade be benched to facilitate compaction efforts and increase surface stability. The compacted thickness of each layer shall not exceed 6 inches. Compaction control and testing should be performed by a qualified testing agency to insure the recommendations of this report are followed. Depending on the amount of rock encountered in the on-site or import soils. We recommend that compaction testing be performed using Sand Cone methods (per ASTM D1556)., or Nuclear Density methods .(per ASTM D2922). If imported off-site material is required to build the pads to finish grade, it must be approved by a representative from our office and meet the following minimum criteria. Import material must have a plasticity index of less than 4; be non -expansive (EI<20); have 100% passing the 3" sieve; 30% to 60% passing the #4 sieve; and no more than 20% passing the 4200 sieve. 3.3 Soil Expansion Potential The surface and near surface soils encountered at the site were found to contain a certain amount of clay, which has potential for volumetric changes. An Expansion Index tests was performed per ASTM D 4829 on one sample, which in our judgment contained the most expansive potential clay (see Attachment 1). The test result indicated an E.I. 12, which is below the limit of 20 set forth in CBC 1802.3.2 and considered to be non -expansive. 3.4 Liquefaction Potential No soils were observed that would be prone to liquefaction in the subsurface excavation. If sands are discovered during site excavation, ATC shall be notified of the presence of such soils. 3.5 In Place Relative Density In Place Relative Density tests were not performed on the surface soils. 3.6 Site Geology & Seismicity Butte County and the surrounding area are located on the western portion of a faulted and downwarped series of ancient metamorphic rocks of the Western Sierra Nevada Mountain Range. Granitic rocks associated with Mesozoic thrust faulting are located in the eastern portion of the County. In the western portion of the County, gently folded younger and sometimes faulted sediments of the Sacramento Valley overlie older metamorphic rocks similar to those of the Sierra Nevada. The stratigraphic and structural trend of metamorphic rocks is generally northward with steeply dipping bedding in most places. The basic site \\Otto\C\Wodc\2008\007-C1ean Rite Soils\reportdoc page 3 Clean-Rite/Build-Rite March 24, 2008 geologic formation is a Pleistocene alluvium (Modesto Formation). The formations and geologic structure of the County appear to be controlled or strongly modified by Cenozoic faults extending along the western portion of the Sierra Nevada Mountains and trending north-northwest along with the Big Bend, Camel Peak, Dogwood Peak, Rich Bar, and Melones faults, most of which lie to the north and east of Butte County in the area of volcanic intrusions. The more recent seismic activity lies with the Cleveland Hills fault (1975-1976), Swain Ravine (Late Quaternary), Spenceville Fault Zone (Late Quaternary, possibly Holocene) and the Highway 49 Fault Zone (Late Quaternary). Most Sierra Nevada faults are a combination of strike slip and thrust .movements. (Bailey, Geology of Northern California, California Division of Mines and Geology.) The site is not within an Alquist-Priolo Special Studies Zone, according to the State of California and the USGS. There are no faults running directly through the site, according to the book "Maps of Known Active Fault Near-Souice Zones in California and Adjacent Portions of Nevada" prepared by California Geological Survey (formerly the California Department of Conservation Division of Mines and Geology) in cooperation with SEAOC. Earthquake related ground shaking should be expected' during the life of structures constructed on this site. The California Geological Survey has defined an active fault as one that has had surface displacement in the last 11,000 years, or has experienced earthquakes in recorded history. Using the EQSEARCH computer program by Blake (2000), a 100 -mile radius search was performed of historic events, (with a minimum magnitude of 4.0), dating from the years 1800 to 2004. A total of 277 earthquakes were found with a maximum magnitude of 6.4; the earthquake closest to the site was about 4.7 miles (7.6 km) away and the largest site acceleration was about 0.171g, (computed using attenuation relationships from Boore et al. 1997, Sadigh et al. 1997,. Abrahamson & Silva 1997 and Campbell & Bozorgnia 1997). Based on the EQFAULT computer program by Blake (2000), the maximum deterministic peak ground acceleration (PGA) was computed to be 0.467g, (again computed using attenuation relationships from Boore et al. 1997, Sadigh et al. 1997, Abrahamson & Silva 1997 and Campbell & Bozorgnia 1997). Based on the California Geological Survey, the probabilistic peak ground acceleration (PGA) that has a 10% probability of exceedance in 50 years was computed to be 0.187g. Properly designed structures, using the current California Building Code requirements, should be constructed to reduce the damage from a strong ground shaking. Based upon our research the following ASCE 7-05 (2007 California Building Code) earthquake design criteria should be used by the Structural Engineer: \\Otto\C\Work\2008\007-Clean Rite SoilsVepomdoc page 4 Clean-Rite/Build-Rite March 24, 2008 ASCE 7-05 Seismic Variables, (USGS based) Site Class: D Ss, Period 0.2 sec.: 0.610g S1, Period 1.0 sec.: 0.233g SMs = Fa x Ss: 0.800g SMI = Fv x S1: 0.450g SDs = 2/3 x SMs: 0.533g SD1 = 2/3 x SMI: 0.300g Seismic Coefficients: Fa 1.312, F,=1.935 3.7 Foundation Design Our field investigation and laboratory test results indicate that the existing native soils, at the proposed site, are adequate for support of lightweight residential construction and an agricultural storage facility. The buildings proposed for this site may be supported upon conventional spread footings and continuous perimeter footings. Based on results of our laboratory testing performed on samples of the predominant soil type encountered, foundations should be designed in accordance with the recommendations provided below. For this project, finish pad subgrade shall be defined as, "the surface on which the capillary break/moisture barrier materials are placed." Foundations bearing on native or fill materials may be sized for vertical compression loads utilizing maximum allowable soil pressures of 1,500 pounds per square foot (psf for dead and live loads, and may be increased to 2,000 pounds for all loads including wind or seismic forces. Lateral sliding resistance may be .computed using a friction coefficient of, p = 0.35. Foundation designs accounting for lateral bearing may use a lateral bearing pressure of 250 - PH Plasticity index testing, along with gradation analysis, were performed on several samples that are representative of the subsurface soil types encountered. The results of these tests are included in the attachments. Although the structural engineer should make the final determination of foundation reinforcement, we recommend as a minimum, that foundations contain a single #4 bar placed at the top and bottom of all foundations. It is further recommended, that foundation reinforcement should be consistent. 3.8 Slab -on -Grade Interior slab -on -grade floors should be underlain with a 4" layer of free -draining gravel. The gravel should be graded, such that, 100% passes the 1" sieve, and not more than 2% passes the #4 sieve. Over the gravel, should be a durable vapor barrier of visqueen, which is 10 ml. \\0tto\6Work\2008\007-C1ean Rite Soils\report.doc page 5 Clean-Rite/Build-Rite March 24, 2008 or thicker, covered by 2" of moist, clean sand. These will both serve as capillary moisture deterrents, as well as, to promote uniform curing of the slab concrete. For slab -on -grades, we recommend that slabs be reinforced with reinforcing bars or welded wire fabric. This reinforcing will minimize cracking, if minor differential settlement occurs beneath the slab. It is important. that the slab reinforcing be located in the middle of the. slab, and it be held in place during concrete placement. See section 3.3 for additional subgrade recommendations. Contraction joints should be installed at intervals not to exceed twenty feet in any one direction. Such joints may be formed by deep (3/4") wet grooving while the concrete is still plastic, or by the installation of Zip Strips. 3.9 Pavement Desio We have been advised that pavement design would not be required within this report. However, we were requested to provide R -Value testing on a sample of material encountered within the proposed street sections. One sample was obtained for R -Value testing. The results of the R -value testing areas follows: Table 1.0 - R -Value Test Result Test Pit # Sample Depth Exudation Pressure (psi) R -Value TP4 18" 300 20 4.0 LIMITATIONS Our recommendations are based upon the information provided regarding the proposed construction, combined with our analysis of site conditions revealed by the field exploration and laboratory testing programs. We have used our best engineering judgment, based upon the information provided and the data generated from our investigation. Our test pits were - dug in locations determined to be representative of the site. However, if the proposed construction is modified or re-sited, or if it is discovered during construction that subsurface conditions differ from those encountered at the boring locations, we should be afforded the opportunity to review the new information or changed conditions, to determine if our conclusions and recommendations must be modified. We do not claim that our _ recommendations are suitable for discovery items or other site changes other than the conditions and testing specifically discussed in this report. Furthermore we cannot be held responsible for discovery items or other site changes. The investigation is intended to develop geotechnical recommendations from the soils and conditions revealed by the test pits and subsequent laboratory work. It is not intended that our investigation will un -earth or detect items or problems deliberately or inadvertently concealed by others. Ash pits, buried trees or other concealed items and their discovery are not the responsibility of ATC. Furthermore we cannot be held responsible for concealed items. \\Otto\C\Work\2008\007-Clean Rite Soils\report.doc page 6 1 1 � Clean-Rite/Build-Rite March 24, 2008 If there is a substantial lapse of time between the submission of our report and the start of construction at the site, or if the conditions have changed, due to natural causes or construction operations at, or adjacent to the site, we urge that this report be reviewed to determine the applicability of the conclusions and recommendations considering the changed conditions and time lapse. This report should not be used after 3 years. We would appreciate the opportunity to review the final plans and specifications to determine if the intent of our recommendations has been implemented in those documents. Applied Testing Consultants is not the foundation design engineer for this project. Design for consolidation, differential settlement and bearing on fill materials are by others. We emphasize that Applied Testing Consultants does not represent that these test results and/or recommendations are suitable, whether or not modified, for any other site or development on. this site, other than the one for which they were specifically prepared. Applied Testing Consultants disclaims responsibility for these test results and/or recommendations if they are used whole or in part at any other site or type of development on this site.
