Borings were performed by Element <br /> Materials Technology(formerly Stork Twin City Testing) in 2007 and 2012 as part of the proposed 2013 <br /> Pavement Management Plan for Arden Hills, Minnesota. <br /> Project Background <br /> Based on your email, it is our understanding that the City of Arden Hills is considering improvements to <br /> approximately 0.7 miles of City streets in 2013 as part of their system-wide pavement management <br /> plan. The improvements being considered include either pavement reclamation or total reconstruction. <br /> Both improvements would include some watermain replacement and the addition of some new storm <br /> sewer. If reconstruction is selected,the project would also include the addition of curb and gutter. <br /> We understand that the planned improvements include portions of Asbury Avenue, Edgewater Avenue, <br /> Glenhill Road and Ridgewood Road,as per the attached map. We also understand that the City of <br /> Roseville improved portions of Asbury Avenue and Ridgewood Road in 2008, adjacent to the municipal <br /> border. <br /> We were contacted on August 28,2012 by the City's Assistant City Engineer, Mr.John Anderson,to <br /> provide our geotechnical opinion related to the existing boring logs. The soil borings were performed in <br /> 2007 and 2012 by Element Materials Technology. Borings logs produced by Element Materials <br /> Technology were provided to us by the City and are attached for reference. The boring logs for 2012 <br /> were noted by Element Materials Technology as draft logs. <br /> Soil and Groundwater Findings <br /> The borings were conducted at 6 locations in the area of interest and a summary of the findings is <br /> presented in Table 1. As per the logs provided,the borings were extended to depths of five to six feet. <br /> The boring numbers presented below correspond to those provided on the boring logs. <br /> AA/EOE Providing engineering and environmental solutions since 1957 <br />
