City of Mounds View 1 2040 Comprehensive Plan DRAFT September 21, 2020 Functional Classification Functional classification is a system to establish the hierarchy of streets that collect and distribute traffic from residential neighborhoods to the metropolitan roadway system. The Metropolitan Council has established a functional classification system for the Twin Cities metropolitan area. Classifications of streets in Mounds View include principal arterials, minor arterials, collector roadways, and local streets. The functional classifications of roadways in Mounds View and associated traffic volumes are shown in Figure 5-1. Functional classification helps to ensure that non -transportation factors, such as land use and development, are taken into account in planning and design of the roadway system. The two major considerations in the classification of roadway networks are access and mobility. Mobility is of primary importance on arterials and thus limiting access is a necessity. However, the primary function of a local roadway is access. This in turn limits mobility. The extent and degree of access control is an important factor in the function of a roadway facility. The functional classification types are dependent upon one another in order to provide a system of streets and highways. Minor Arterials — Mounds View Boulevard, Silver Lake Road: Minor arterial roadways connect the urban service area to cities and towns inside and outside the region and generally service medium to short trips. Minor arterials connect principal arterials, minor arterials, and collectors. The spacing range from '/ to 3/ of a mile in metro centers to 1 to 2 miles in developing areas. The desired minimum average speed during peak traffic periods is 20 mph in fully developed and 30 mph in developing areas. The emphasis for minor arterial roadways is on mobility rather than on land access. In urban areas, direct land access is generally restricted to concentrations of commercial/industrial land uses. • Mounds View Boulevard (A -Minor Reliever): Defined as a road that provides direct relief for metropolitan highway traffic. 4 lanes + turn lanes, and no anticipated changes to number of lanes. • Silver Lake Road (A -Minor Expander): Defined as a road that provides a way to make connections between urban areas outside the 1-494/1-694 beltway. 4 lanes and no anticipated changes to number of lanes. Principal Arterials - Interstate 35W, State Highway 10: Principal arterial roadways serve major activity centers, higher traffic volumes, longer trips, and carry a higher proportion of total urbanized travel on a minimum of mileage. Along these facilities, the City and other agencies limit access to preserve the ability of the roadway to accommodate the volumes and to maximize safety for drivers. The management criteria require that a 40 mph average speed be achieved during peak traffic periods. Also, little or no direct land access should be allowed to these roadways. Grade separated intersections are required for freeways and highly desired for other principal arterial roadways. Interstate 35W is between 6-8 lanes as it travels through Mounds View and no additional lanes are planned at this time. A MnPASS lane is currently under construction on 1-35W. State Highway 10 is currently 4-6 lanes and no additional lanes are planned at this time. MOUNDS VIEW i Chapter 5: Transportation 1 5-3
