1.0 INTRODUCTION <br />1.1 Project Description <br />The City of Ramsey (City) is preparing to complete roadway improvement projects within 3 <br />general areas of the City during the 2022 construction season. These areas included; the Sunwood <br />Drive and Waco Street Area, the Autumn Heights Area and the Wood Pond Hills 2nd - 5th Area. <br />To aid in preparing design and construction documents the City solicited bids to perform a <br />geotechnical exploration within each of the 3 areas. <br />Haugo GeoTechnical Services (HGTS), was the successful bidder for the 3 projects. This report <br />presents the results of the 31 soil borings advanced along the various roadway alignments within <br />the Autumn Heights area. <br />1.2 Purpose <br />The purpose of this geotechnical exploration was to determine existing bituminous pavement <br />section thicknesses, characterize subsurface soil and groundwater conditions and provide <br />recommendations for roadway design and construction. <br />1.3 Site Description <br />The streets with the Autumn Heights area are located on both sides of Armstrong Boulevard NW <br />and are generally located between Tiger Street NW and Jackal Street NW. The streets slated for <br />improvements included; 167th Lane NW, 168th Lane, Nutria Street, 168th Avenue NW, Rabbit Street <br />and 169th Avenue NW. Each street is a 2-lane bituminous surfaced, rural residential roadway that <br />provides access to single family homes. <br />Each of the streets slated for improvement was noted to contain numerous cracks, both <br />longitudinal and transverse cracks as well as some "alligator" cracking. We also observed several <br />patched areas. <br />1.4 Scope of Services <br />Our scope of services was performed in accordance with the City of Ramey REQUEST FOR <br />PROPOSAL, PAVEMENT MANAGEMENT PROGRAM, 2022 PROJECTS issued on July 20, 2021. <br />Our scope of service for the Autumn Heights project included the following tasks: <br />• Performing 31 standard penetration test borings each to a nominal depth of 10 feet. <br />• Coring the pavement at 31 locations to measure the thickness of the existing bituminous <br />and aggregate base. <br />• Visually/manually classifying samples recovered from the soil borings. <br />• Performing laboratory tests on selected samples. <br />• Preparing soil boring logs describing the materials encountered and the results of <br />groundwater level measurements. <br />1 <br />
