GEOTECHNICAL EXPLORATION CITY OF RAMSEY IMPROVEMENTS PROJECT 25-07 VARIOUS GRAVEL ROADS RAMSEY, MINNESOTA ITT PROJECT 24-327 A. Introduction This report is being prepared for use by our client on this specific project. We intend to present this report and our findings in the same logical manner that led us to arrive at our recommendations. This report is based on some general assumptions regarding the anticipated construction based on experience with similar projects. These assumptions and the entire report should be reviewed immediately upon receipt. Purpose: The purpose of our investigation was to evaluate the existing soil and water conditions on numerous gravel roads throughout the City of Ramsey for the purpose of paving the existing roadways. The project has six different areas of roadways. Area A on the north side of the city includes Xenolith Street NW and Carolyn Lane NW. Area B on the north side of the city includes Garnet Street NW.

Area F on the southwest side of the city includes Beatty Avenue NW And Collins Drive NW. In accordance with your written authorization, we have conducted a subsurface exploration program for the proposed project. Scope of Services: Our authorized scope of services included the following: 1. To investigate the subsurface soil and water conditions encountered at twenty- four (24) split -spoon soil boring locations. The borings were planned in the roadway surface to depths often (10) feet at each location. 2. To provide a report of our findings including a summary of our findings with aggregate thickness at each boring location as well as recommendations regarding earthwork, sill and compaction, subgrade preparation, and pavement design with an estimated design R-value.
