. . . Roadway Improvements In addition to the roadway improvements assumed in the 2005 No-Build condition, the 2005 Build condition assumes that existing Guidant Drive North will be turned over to the City and will become a public street requiring the street to be modified to meet the City of Arden Hills public street design standards. These improvements will likely require a traffic signal to be added to the intersection of Guidant Drive North and Lexington Avenue. Traffic signal timing was also assumed to be optimized along Lexington A venue to account for the higher volumes of traffic being experienced on the roadway network due to the Guidant Campus site growth. The roadway geometry for the 2020 Build conditions are the same as the 2005 Build conditions, with the addition of a north-south connection being extended north of CR 96 to CR I. This improvement was also assumed in the 2020 No-Build. Traffic Operations Analysis Tables II and 12 display the results of the signalized and unsignalized intersection analysis for the 2005 and 2020 Build traffic conditions. With limited public improvements planned between 2005 and 2020 and traffic volumes estimated to increase, the LOS at roadways will continue to decline and the majority of intersections will experience a LOS E or F by 2020.
