1.0 INTRODUCTION 1.1 Project Description The City of Ramsey in conjunction with their civil engineering consultants, Hakanson Anderson, is preparing to complete roadway improvements within four areas of the city during the 2024 construction season. The street improvements well be completed under 2 separate city project numbers, IP 24-03 and IP 24-05. City Project IP 24-03 will include residential street within 3 areas of the city and City Project IP 24-05 will consist of resurfacing Xkimo Street. To aid in preparing design and construction documents, Hakanson Anderson, on behalf of the city, solicited bids to perform a geotechnical exploration for each project. Haugo GeoTechnical Services (HGTS), was the successful bidder for both projects. This report presents the results of the 24 soil borings advanced along the various roadway alignments within the IP 24-03 Street Reconstruction areas. 1.2 Purpose The purpose of this geotechnical exploration was to determine existing bituminous pavement section thicknesses, characterize subsurface soil and groundwater conditions and provide recommendations for roadway design and construction. 1.3 Site Description The streets slated for reconstruction/improvements under City Project IP-24-03; • Vanadium Street between Green Valley Road and 18011, Lane • 178th Lane NW from about 300 feet west of Vanadium Street to Uranium Street • 180th Lane NW between Vanadium Street and Uranium Street • Uranium Street from about 150 feet north of 180th Lane NW to 178th Lane NW • 179th Lane NW from Uranium Street to about 300 feet east • 177th Lane NW from Vanadium Street to end • Waco Street from 179th Lane NW to north end of Waco Drive • Waco Drive • 1801h Avenue NW from Barium Street to about 300 feet east • Barium Street NW from 179th Lane to end • 180th Avenue NW from Barium Street to end Each street is a 2-lane bituminous surfaced roadway that provides access to single family homes. Each of the streets slated for improvement was noted to contain numerous cracks, both longitudinal and transverse cracks as well as some "alligator" cracking. We also observed several patched areas. The roadway/pavement surface was relatively level but varied along the alignments and varied between the different areas within the city. Overall, ground surface elevations at the boring location ranged from about 880 to 908 feet above mean sea level.
