City of Arden Hills – 2030 Comprehensive Plan Approved: September 28, 2009 11-10 As a component of the TCAAP AUAR, an analysis of intersection level of service was conducted on future conditions for the Minimum and Maximum scenarios. With the mitigation measures identified in the traffic analysis, all intersections operate at an acceptable LOS of D or higher. Generally, the recommended Geometric Design Standards and associated right- of-way width requirements illustrated in the Geometric Design Standards should maintain the corridor’s capacity to accommodate the forecasted traffic volumes on the City’s roadways (Appendix B). Capacity improvements are recommended on any roadway with a future level of service of D, E, or F, as defined in the roadway capacity discussion within the Transportation System Principals and Standards (Appendix B). Roadways identified above as near congested or congested are recommended to be monitored and programmed for capacity improvements when necessary. Roadways that are periodically congested are generally identified as providing an acceptable level of service. 11.3.2 Roadway Safety & Mobility Needs Many of the roadways within and adjacent to the City of Arden Hills are in need of capacity improvements by 2030 due to the anticipated growth throughout the area. This is due not only to growth within the City of Arden Hills but also growth within adjacent cities and other cities along the freeway and highway corridors. With this increase in development and increase in traffic, an increase in congestion is expected for most roadways throughout Arden Hills. Improvements are recommended for Hamline Avenue, Lexington Avenue, Old Highway 10, and the interstate freeways. The expansion and reconstruction of I-694 will improve operations, especially from I-35W to TH 10, even with the increased traffic expected by 2030. The other areas of I-694 will likely be congested as much as they are today by 2030. Since the primary roadways providing significant mobility within the City of Arden Hills are county and state roadways, the City will need to coordinate with the State and County on roadway improvements. Collector roadways carrying greater than 1,500 vehicles per day have volumes that tend to create potential conflicts between vehicles, bicycles, and pedestrians. The City, in cooperation with Ramsey County, will need to monitor pedestrian and bicycle issues, crashes, near misses, and complaints, and prioritize roadway improvements with pavement rehabilitation needs. Strategies to improve safety and mobility will be considered, including the consideration of adding pedestrian facilities at intersections, non-motorized facilities both along and separate from roadways, additional roadway width for wider lanes or
