The provided text appears to be a geotechnical engineering report for the Eagle River Tennis Courts Rehabilitation project in Eagle River, Alaska. Here's a summary of the report: **Introduction:** The report presents the results of subsurface explorations and laboratory testing conducted by Shannon & Wilson, Inc. to investigate the cause of depressions observed in the existing tennis court surface. The study aimed to explore subsurface conditions and provide geotechnical engineering analysis to better understand the subsurface conditions. **Site and Project Description:** The project is located on the corner of Fire House Lane and Seabolt off Eagle River Road in Eagle River, Alaska. The site contains two tennis courts with a fenced perimeter and a generally flat tennis surface. A depression has formed in the north end of the eastern tennis court, which is about six inches deep and has a linear feature extending out of it. **Subsurface Explorations:** Six geotechnical borings (B-1 to B-6) were drilled on January 14, 2026, to evaluate the subsurface conditions at the site. The borings were advanced using a rubber track drill rig, and samples were recovered using the Standard Penetration Test (SPT) or Modified Penetration Test (MPT) methods. The samples were observed and described in the field, and selected samples were tested in the laboratory to refine the soil descriptions. **Objectives:** The objectives of the report are to: 1. Evaluate the subsurface conditions at the site 2. Determine the cause of the settlements and depressions observed in the existing tennis court surface 3. Provide geotechnical engineering recommendations for the rehabilitation of the tennis courts **Report Contents:** The report includes the following sections: 1. Introduction 2. Site and Project Description 3. Subsurface Explorations 4. Laboratory Testing 5. Subsurface Conditions 6. Engineering Conclusions (including site preparation, subgrade development, surfacing structural section, drainage, structural fill, and compaction) 7. Closure and Limitations The report also includes several figures, including a vicinity map, site plan, and gradation requirements, as well as appendices containing boring logs, laboratory test results, and other supporting information.
