City of Arden Hills – 2030 Comprehensive Plan Approved: September 28, 2009 11-2 that it performs adequately. As such, whether an existing roadway is proposed for upgrading or a land use change is proposed on a property, this Plan provides the framework for decisions regarding the nature of roadway infrastructure improvements necessary to achieve safety, adequate access, mobility, and performance of the existing and future roadway system. This chapter includes established local goals, policies, standards, and guidelines to implement a future roadway network and transit vision that is coordinated with respect to county, regional, and state plans in such a way that the transportation system enhances quality economic and residential development within the City of Arden Hills. This chapter also includes two appendices. Appendix B describes the general transportation system principles and standards, including functional classification, roadway capacity by type, access management guidelines, geometric design standards, and roadway jurisdiction. Appendix C includes the full transportation forecast and traffic modeling methodology. 11.2 EXISTING TRANSPORTATION SYSTEM EVALUATION The transportation system in Arden Hills includes a roadway system that accommodates a variety of vehicles including cars, trucks, and public transit. Transportation also includes pedestrian movement and bicycles, which is also discussed in Chapter 9 (Parks & Recreation) of this Plan. While upgrades will need to be made over time, existing City controlled roads provide sufficient transportation service to the City. 11.2.1 Existing Traffic Volumes and Capacity Issues The existing traffic volumes within the area, which were collected by Mn/DOT, Ramsey County, and the City of Arden Hills, are represented in Figure 11.1 – 2005 and 2006 Average Daily Traffic Volumes. Volume to capacity analysis of the average daily traffic volumes indicates several roadway segments within the City of Arden Hills are currently operating at a periodically congested, near congested, or congested level (Figure 11.2). Additional data regarding segment design type and capacity is available within Appendix B. Based on available traffic volume data, the following roadways are classified into the following groups: Level of Service C – Periodically Congested • TH 10 from I-35W to I-694 • TH 51, South of CSAH 50/Hamline Avenue • CSAH 50/Hamline Avenue from CSAH 96 to I-694 • CSAH 51/Lexington Avenue from CR I to CSAH 96 • CSAH 51/Lexington Avenue, South of CR F
