The following improvements are recommended to improve traffic operations on adjacent roadways: 2005 Recommended Improvements . An additional northbound left turn lane at Lexington Avenue/CR F. A southbound and northbound right turn lane at the intersection of the 1-694 ramps with Lexington Avenue. Installation of traffic signals at Lexington Avenue/Guidant Drive North and Hamline Avenue/CR F. . . 2020 Recommended Improvements . A dedicated westbound right turn lane at Hamline Avenue/CR F. An additional eastbound left turn lane at the intersection of the 1-694 ramps and Lexington Avenue. If a north-south connection is extended north of CR 96 to CR I, a new lane configuration is recommended to be built for the southbound movement at the intersection of this connection and CR 96. . . Improvemcnts to Lcxington Avenue, Guidant Drive South, Hamline Avenue and West floral Drive are not recommended due to low cross street volumes and signal spacing constraints. BUILD CONCLUSIONS 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 Avenue 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 thc 2005 Build conditions, with the addition of a n0l1h-soutb connection north of CR 96 to CR 1. This improvement was also assumed in the 2020 No-Build. With limited public improvements planned between 2005 and 2020 and traffic volumes estimated to increase, the LOS at adjacent roadways will continue to decline and the majority of intersections will experience a LOS E or F by 2020. MITlGA TION MEASURES Guidant has worked with Mn/DOT, Ramsey County and the Cities of Arden Hills and Shoreview to identify appropriate roadway improvcments to mitigate for traffic impacts that may rcsult from thc thrcc stagcs of development (Phases I, 1I and III) planned as part of Guidant Campus Master Plan Final AUAR and Mitigation Plan January 2003 - 60-
