The exploration consisted of excavating 10 test pits to determine subsurface conditions, performing limited laboratory testing on representative soil samples, performing engineering analyses of the subsurface soils, and preparing this report, which summarizes the exploration and presents our preliminary recommendations. This report contains preliminary recommendations for planning and development of the site and should not be used for final design and construction. Our recommendations do not address the construction of residences. Additional exploration, laboratory testing, and recommendations will be necessary after the details of the proposed development have been determined. The recommendations contained in this report are based on the results of our field exploration, laboratory testing, engineering analyses, and our understanding of the proposed project. PROJECT DESCRIPTION We understand this project consists of developing approximately 75 acres of land located at the southeast corner of West Chinden Boulevard and North Linder Road in Meridian, Idaho. The proposed project will primarily be a commercial development with associated roadways and parking area. We understand a small residential development is planned near the southeast portion of the site. Current plans for the development are conceptual at this time so the location of buildings and infrastructure are unknown. SITE EXPLORATION PROCEDURES Field Exploration ' The subsurface exploration consisted of excavating 10 test pits. The approximate locations of the test pits are shown on Figure 1 — Test Pit Location Plan, which is included in l Appendix A. 1 Chinden and Linder Development Terracon Project No. 62075514 August 9, 2007 Terracon The test pits were located in the field by Terracon by measuring from existing site features with a measuring wheel. Relative ground surface elevations at test pit locations were measured by Terracon using a laser level. Elevations reported on the test pit logs are rounded to the nearest Y2 foot. The top of the concrete base for the signal pole located at the southeast corner of West Chinden Boulevard and North Linder Roadwas used as a temporary benchmark (TBM). The elevation of the TBM was assumed to be 100.0 feet. The approximate location of the TBM is shown on Figure 1 — Test Pit Location Plan in Appendix A. The locations and elevations of the test pits should be considered accurate only to the degree implied by the means and methods used to define them. The test pits were excavated to depths ranging from about 5.5 to 11 feet below the existing ground surface with a backhoe. A Terracon field engineer/geologist recorded logs of the test pits during the drilling operations. Disturbed soil samples were obtained at various depths in the test pits. Descriptions of the materials encountered are shown on the test pit logs. Laboratory Testing Samples obtained during the field exploration were taken to the laboratory where they were visually classified in general accordance with the Unified Soil Classification System (described in Appendix B). Representative soil samples were selected for testing to determine the engineering and physical properties of the soil. Laboratory tests conducted and a brief description of the purpose of each test are listed below. The results of the laboratory tests are included on the test pit logs in Appendix A. TABLE 1 — LABORATORY TESTING Tests Conducted To Determine Natural Moisture Content Moisture content representative of field conditions at the time samples were taken. Percent Passing No. 200 Amount of clay and silt in a sample. Sieve Grain -Size Distribution Size and distribution of soil particles, used for classification. Atterberg Limits The consistency and range of moisture content within which the material is workable. 2 Chinden and Linder Development Terracon Project No. 62075514 August 9, 2007 SITE CONDITIONS Terracon j At the time of our exploration, the approximately 75 -acre site consisted primarily of farm ground with a residence and several farm buildings located near the center of the northern side of the site. Chinden Boulevard and Linder Road bordered the site the north and west, respectively. Residential developments bordered the site the east and south. Several ditches and canals were present at the time or our field work. The approximate location of these features is shown on Figure 2 in Appendix A. Standing water was present east of the residence at the time of our field work, possibly from the ditch adjacent to the residence driveway. We also observed the presence of some stock piles of uncontrolled fill/ trash, and a domestic well (shown on Figure 3). We understand the existing residence has a basement and a septic system. The approximate location of the septic tank is shown on Figure 3 in Appendix A. Our Phase I Environmental Site Assessment (dated July 25, 2007) should be reviewed for additional information about existing man-made features. SUBSURFACE CONDITIONS Soil Conditions (� The subsurface conditions encountered at the test pit locations are indicated on the individual test pit logs included in Appendix A. Stratification boundaries on the logs represent the approximate depths of changes in soil types; in situ, the transition between I I materials may be gradual. The subsurface profile generally consisted of silt and sand mixtures underlain by medium dense to very dense silt, sand and gravel mixtures. Slight to strong cementation was observed in many locations below four feet. Approximately 6 to 12 inches of the upper soil was apparently disturbed/loosened due to farming activities. Groundwater Conditions The test pits were monitored during excavation for the presence of groundwater. Groundwater was not encountered in the test pits during our field work.. Fluctuations of the depth to groundwater may occur due to seasonal variations in the amount of irrigation, rainfall, snowfall, runoff, the water level in nearby sloughs and canals, and other factors not evident at the time the test pits were drilled. Evaluation of these factors is beyond the scope of this exploration. 3 Chinden and Linder Development Terracon Project No. 62075514 August 9, 2007 PRELIMINARY ENGINEERING RECOMMENDATIONS Geotechnical Considerations Terracon For initial estimating purposes, we have provided preliminary recommendations for general earthwork, foundation recommendations, pavement subgrade preparation, and pavement sections for the streets. Additional exploration, laboratory testing, and recommendations will be necessary after the details of the proposed development have been determined. The 10 test pits we excavated as part of our field exploration were not compacted. As indicated in our proposal, we recommend that a professional surveyor determine specifically the locations of the tests pits. If for some reason buildings or other settlement sensitive infrastructure are positioned over any of the test pits, it will be necessary that the contractor remove the backfill in the test pit and replace it with properly placed and compacted structural fill at the time of construction. Earthwork Though final earthwork recommendations should be provided after additional exploration has occurred, the following guidelines should be considered for planning and development of the property. In preparing the site for construction, deleterious materials such as vegetation, root systems, topsoil, debris, existing fill, organic material, and soft, frozen, or otherwise unsuitable materials should be removed from the proposed building and pavement areas. As indicated previously, the upper 6 to 12 inches of soil in our test pits appears to have been loosened by farming operations. This loosened soil should be removed or moisture conditioned and compacted prior to construction of the proposed developments. Compaction requirements, including density and moisture conditioning, should be determined in subsequent investigations when additional details about the proposed development are known. Special attention should be given to removal of man-made features including (but not limited to) the existing house and basement, the septic system and drain field, uncontrolled fill/trash, underground storage tanks, concrete lined ditches, and soft or organic soil in ditches/canals. Excavations resulting from the removal. of these items should be properly backfilled with structural fill compacted to densities appropriate for the planned construction. Failure to remove these or other deleterious items or failure to place structural fill may result in abrupt differential settlement with associated distress to buildings, roadways, or other infrastructure. 0 1, Chinden and Linder Development Terracon Terracon Project No. 62075514 August 9, 2007 The native fine grained soils may be susceptible to rutting or pumping under construction traffic when wet. Soils which become rutted, pumped, or otherwise disturbed are not suitable for support of pavements, and should be removed and replaced with structural fill. Earthwork should be performed in dry weather to reduce the potential for rutting and pumping soils. If unstable conditions develop, stability may be improved by scarifying and drying. If construction occurs during wet conditions, lightweight or track mounted excavation equipment and dump and spread construction methods may reduce the potential for subgrade pumping. The contractor(s) is responsible for designing and constructing stable, temporary excavations as required to maintain stability of both the excavation sides and bottom, and for protecting existing facilities/utilities. Excavations should be sloped or shored in accordance with local, state and federal regulations, including current OSHA excavation and trench safety standards. Grading operations should be controlled to prevent water from flowing into construction areas. Excessive wetting or drying of the foundation excavation soils should be avoided during construction. Excess water should be promptly removed. Positive drainage should be provided away from the roadways both during and after construction. Failure to provide adequate drainage measures may result in premature pavement failure, softening of soils and ponded water. Foundations For initial estimating purposes, footings for the proposed commercial buildings should be founded at least 30 inches below finished grade for frost protection. Footings should not be founded on loose or disturbed soil. Special care should be given where footings will cross areas where existing man-made features are located. We recommend detailed geotechnical explorations be conducted for each building after the proposed locations of the buildings are known. While the actual bearing capacity should be determined in subsequent explorations, we estimate bearing capacities may range from 1500 to 3000 psf, depending on structural requirements, underlying soils, and the previous use of the land. Pavernen is Two preliminary pavement sections are presented below for estimating purposes. One section is for roadways within the proposed development and one is for parking areas. The pavement sections are based on an assumed R -value of 20. The number of ESALs the pavement sections have been designed for are shown in the table below. Actual pavement sections should be based on geotechnical explorations conducted after grading plans have M Chinden and Linder Development Terracon Project No. 62075514 August 9, 2007 Terracon been developed and additional traffic information is known. Materials used in the pavement section should conform to applicable section of the Idaho Standards for Public Works Construction (ISPWC).

Pavement design for the roadways was based on Idaho Department of Transportation design methods. 2. Pavement design for the parking areas was based on the NAPA publication "Design of Hot Mix Asphalt Pavements for Commercial, Industrial, and Residential Areas." GENERAL COMMENTS l This report is a preliminary exploration to provide general geotechnical guidelines for planning and development of the site. Specific geotechnical explorations should be performed for individual building sites and roadways to determine site specific design parameters and recommendations for foundation and slab support systems, and construction methods. The analysis and recommendations presented in this report are based upon the data obtained from the test pits performed at the indicated locations and from other information discussed in this report. This report does not reflect variations that may occur between test pits, across the site, or due to the modifying effects of weather. The nature and extent of such variations may not become evident until during or after construction. If variations i appear, we should be immediately notified so that further evaluation and supplemental j recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken. This report has been prepared for the exclusive use of our client for specific application to the project discussed and has been prepared in accordance with generally accepted geotechnical engineering practices.
