Scott County has requested the City of Shakopee's support pertaining to the reclassification of certain regional roadways within the city, including County State Aid Highway (CSAH) 42, CSAH 17, CSAH 78, and CSAH 21 (see attached roadway classification map).

Generally, it is the county's goal to have the CSAH 78/42 and CSAH 17 corridors serve as primary east-west and north-south transportation mobility corridors within the county. With that said, the primary effect on the city of classifying these corridors as official Principal Arterial roadways pertains to mobility vs. local access. A Principal Arterial is the highest level of transportation classification, with full focus on regional mobility (vs. local access). The goal of a Principal Arterial is to eliminate all direct access from private property and to minimize local access to a minimum of 1 mile spacing between roadways that intersect the Principal Arterial, again focusing on regional mobility and little to no local access.

Pertaining to CSAH 78, the city completed the West End planning study that supports the classification of CSAH 78 as a Principal Arterial, including the planned access control along this corridor through land development coordination and controls as the city develops. Likewise, the city has worked with the county in the past to improve the access control along CSAH 17, removing direct access driveways, building frontage roads, and building an interchange at the intersection of CSAH 17 and CSAH 42, setting the basis for CSAH 17 to be classified as a Principal Arterial.

Similarly, the county completed a study for CSAH 42 dating back to 1996, which laid out certain access spacing for the CSAH 42 corridor. Subsequently and most recently, the county has proceeded with the planning and design of their CSAH 42 four-lane expansion project to be constructed in 2020. As part of this project, the county is desiring to further limit local access (see attached letter), eliminating access in a location which was previously designated to include local access, specifically at a location midway between the CSAH 17 interchange and existing intersection at Dakota Parkway (see CSAH 42 Access Map). With the elimination of this access to the regional roadway, it would generally require the city to reguide the planned land use as part of Envision Shakopee in this area, changing it from Mixed Residential, a use that would allow certain uses other than residential such as neighborhood commercial (e.g. a

neighborhood convenience store/gas station). Eliminating this access point would require any development of the adjacent land to connect into and extend the existing roadways to the north, roadways which are primarily residential in nature. Being sensitive to the nature and use of these existing roadways, it would be recommended to similarly guide this area as Suburban Edge and/or Open Space (see attached Land Use map), generally extending the nature of the area as residential and not mixing in any commercial that would then rely on the neighborhood roads for access. The county has indicated their intent to purchase access control along the county road from these properties, thus resulting in the opportunity to revise the land use for this area as indicated above. 

The reclassification of CSAH 21 from a Principal Arterial to a lesser Minor Arterial is insignificant to the city as the access control along CSAH 21 has generally been set through the adjacent development and infrastructure that has occurred and been constructed over the past decade.

With the support of the city, the county will seek official reclassification as part of an official process with the Metropolitan Council. It should be noted that the City of Prior Lake and the SMSC are in general support of the reclassification as proposed.
