To develop the criteria for use in design, 54 test pits were excavated at the site. Percolation tests were conducted in 19 test pits by KND Engineering of Eagle River, Alaska. Soil samples recovered from the test pits were returned to the Shannon & Wilson laboratory for visual classification and testing. Included in this report are a description of the site and project, subsurface explorations and laboratory test procedures, and interpretation of the subsurface conditions. Written authorization to proceed with this work was received from Alison Smith of the Alaska Mental Health Trust Land Office on September 4, 1998. 2.0 SITE AND PROJECT DESCRIPTION The 120 acre parcel of land is generally "L" -shaped and is located west of Goldenview Drive, south of 172"d Avenue, and east of the gas pipeline trail in south Anchorage, Alaska. It is understood that a 15 acre parcel in the southeast corner of this parcel may be traded with a 11.35 acre parcel of land owned by the Heritage Land Bank located generally west of the gas pipeline. A general vicinity map is presented in Figure 1. One test pit was excavated on the Heritage Land Bank's 11.35 acre parcel of land. Four test pits were proposed for this parcel. Due to the steep terrain, the excavator was only able to travel to one location. This generally shows that this land will be difficult to develop. At the time of the exploration, the site was undeveloped and covered with alder, spruce, and birch trees and devil's club. There was an organic mat over the area. There were'several small TABLE OF CONTENTS 1.0 INTRODUCTION.................................................................... 1 ....................................... 2.0 SITE AND PROJECT DESCRIPTION ...................... 1 ................................................. 3.0 SUMMARY OF FIELD EXPLORATIONS ........................................ 2 ........................ 4.0 LABORATORY TESTING .......................................... 3 ..................................... 5.0 SUBSURFACE CONDITIONS............................................................................................3 6.0 CONCLUSIONS...................................................................................................................4 7.0 CLOSURE AND LIMITATIONS.........................................................................................5 LIST OF FIGURES Figure 1 Vicinity Map Figure 2 Site Plan Figure 3 Soil Classification Legend LIST OF APPENDICIES Appendix A Test Pit Logs Appendix B Percolation Test Data Appendix C Grain Size Classifications Appendix D Important Information about Your Geotechnical Report SHANNON & WILSON, INC. swampy areas with drainage creeks that flowed down the hillside. A detailed site plan is presented in Figure 2. As shown by the contours on the site plan, this site is on a hillside location, which generally slopes to the west. There is approximately 400 feet of grade change from Goldenview Drive to the gas pipeline trail. The horizontal distance is approximately 2700 feet. This translates into an overall slope of approximately 15 percent. 3.0 SUMMARY OF FIELD EXPLORATIONS Fifty-four test pits, designated TP -1 through TP -54, were excavated at the site from September 14 through September 18, 1998 to define subsurface conditions. The locations of these test pits are shown in Figure 2. These locations were surveyed by Crazy Mountains Joint Venture of Anchorage, Alaska. Soils encountered were visually classified in the field and verified by laboratory testing according to the Unified Soils Classification System that is presented in Figure 3. Detailed logs of the test pits are presented in Appendix A. Table 1 summarizes the test pit locations and includes the state plane coordinates and elevations for the test pits. Percolation tests were conducted according to current DEC standards by KND Engineering. Detailed percolation test logs are presented in Appendix B. Table 2 presents a summary of the percolation tests. Excavation services for this project were provided by B -C Excavating of Anchorage, Alaska using a Hitachi EX -200 track mounted excavator. An experienced engineer from Shannon & Nilson, Inc. was present continuously during excavation to locate the test pits, collect samples, log subsurface conditions, and monitor any groundwater encountered. The test pits were advanced to depths of about 15 feet. Many of the test pits were advanced to lesser depths due to bedrock or very hard material. The sampling plan included collecting samples from each soil layer encountered in the test pits. As the test pits were excavated, samples were recovered from either the bucket of the excavator or the stockpiled. material. Many of the test pits had a four -inch diameter HDPE perforated pipe installed to monitor groundwater in the future. The presence of the wells is noted graphically in the test pit logs in Appendix A. i ne Lana utrice, c9oldenview Tract October 8, 1998 Anchorage, Alaska Page 2 Alaska Mental Health Trust Land Office, Anchorage, Alaska A-997 SHANNON & WILSON, INC. At the end of the excavation, the test pits were backfilled with native material. Most of the test pit locations were staked prior to excavation by the surveyor. All test pits were staked or marked on the well upon completion for a physical marker of the test pit. 4.0 LABORATORY TESTING Laboratory tests were performed on all samples recovered from the test pits to verify field classifications and to determine the pertinent behavior characteristics of the typical materials encountered at the site. The laboratory testing was formulated with emphasis on determining the material classification, moisture, and frost characteristics. Twenty-nine water content tests were performed on samples from the test pits. These tests were conducted in accordance with procedures described in ASTM D-2216. The results of the water content measurements are presented on the test pit logs in Appendix A. Grain size classification tests for this project consisted of twenty-nine mechanical sieve analyses to confirm the field classifications and to estimate permeability characteristics and frost susceptibility. These tests were conducted generally according to procedures described in ASTM D-422. The results are presented on Appendix C. 5.0 SUBSURFACE CONDITIONS The subsurface conditions at the site are depicted in detail on the test pit logs in Appendix A. The test pits for this study encountered somewhat similar material in all of the holes. The typical soil profile started at the surface with a one -foot thick orange brown silty sand organic mat, followed by brown, silty, gravelly sand (glacial till), which extends to the bottom of the test pits. The dominant soil layer below the organic mat had a substantial number of cobbles near the surface. The cobbles were present, usually in lower concentrations, to the bottom of all of the test pits. The general soil description is consistent with a glaciofluvial deposit. Some of the localized low areas tended to be swampy. At these locations there was typically several feet of soft, black peat and organic silt overlying glacial till. These areas tended to be quite wet at the surface. The glacial till in these areas seemed to have more blue clay/silt than other areas of the site. I he Land Uttice, Goldenview Tract October 8, 1998 Anchorage, Alaska Page 3 Alaska Mental Health Trust Land Office, Anchorage, Alaska A-997 SHANNON & WILSON, INC. Based on the conditions encountered while excavating the test pits, it is believed that the granular soils are generally medium dense to very dense. The test pits generally had vertical sidewalls during the excavation of the pits. Also, there was difficulty while digging through the cobble -rich sand zone, due to the very dense nature of the deposit. The moisture contents of the soil samples ranged from about three to 29 percent. Groundwater was encountered during excavation of many test pits. Depending on the soil profile, the depth to groundwater varied from the surface to below the bottom of the test pit at 15 feet. In our experience, fluctuations in the groundwater of five feet or more may occur due to seasonal changes in snowmelt and rainfall. 6.0 CONCLUSIONS The soils encountered on the site are similar to those found over much of the hillside. The groundwater conditions and depths to substantial refusal are also similar. In summary, with respect to future development, the following conclusions can be made: 1. Building foundations will not require unusual engineering. In some areas, shallow groundwater may require subdrains. Standard spread footings will provide adequate support for low-rise structures. 2. The near surface soils are typically moderately frost susceptible. These conditions can be incorporated into design for road, streets and drainage. Some areas have water near the surface and would likely glaciate in the winter, if a road is present. 3. Percolation tests indicated generally slow permeability, similar to most areas on the hillside. This, coupled with areas of high groundwater and shallow bedrock will require alternative systems for septic disposal in some portions of the property. Additionally, some of the land has a slope greater than 25%, making on-site disposal very difficult. 4. The Heritage Land Bank parcel to the west of the gas line is very steep, and as such is marginally developable, either as a school site or as a residential development.

If during construction, subsurface conditions different from those encountered in the exploratory holes are observed or appear to be present beneath excavations, we should be advised at once so we can review these conditions and reconsider our recommendations, when necessary. If substantial time has elapsed between submission of this report and the start of work at the site, or if conditions have changed because of natural causes or construction operations at or adjacent to the site, we recommend that this report be reviewed to determine the applicability of the conclusions and recommendations considering the time lapse or changed conditions. Unanticipated soil conditions are commonly encountered and cannot be fully determined by merely taking soil samples or excavating test pits. Such unexpected conditions frequently require additional expenditure be made to attain a properly constructed project. Therefore, some contingency fund is recommended to accommodate such potential extra costs.
