The reconstruction and expansion of County State Aid Highway (CSAH) 42 has been programmed by Scott County as part of their Transportation Improvement Program (TIP) in 2020. A portion of the proposed reconstruction is within City of Shakopee municipal limits and thus the city is required to participate in the cost of the reconstruction project per the county's funding policy. City staff has been coordinating with Scott County staff on preliminary design review and the county has prepared 95 percent plans and cost estimate.

The proposed reconstruction project would expand CSAH 42 from two lanes of traffic to four lanes of traffic between CSAH 17 in Shakopee and CSAH 83 in Prior Lake. The proposed project will also provide pedestrian trails and expand stormwater treatment for the roadway. As part of the project, all utility relocations (existing overhead) and new utility lines will be installed underground per the City of Shakopee Right-of-Way ordinance.

Scott County's Local Cost Participation Policy is included as Exhibit A. CSAH 42 is designated a Principal Arterial and thus the City of Shakopee is required to pay for 7.5 percent of Roadway Improvements, 50 percent for Aesthetics, 30 percent for Right-of-Way, 50 percent for Multi-Use Trails & Sidewalks and 100 percent for City Utilities. In addition, Engineering & Construction Engineering is based on the share of construction costs. Attached is the Preliminary Cost Estimate prepared by Scott County based on the 95 percent plans. 

The following are several key points and items that will continue to be worked out as part of the ongoing plan development and cost participation:

The county's policy is to construct 8-ft wide trails along roadway corridors unless they are designated regional trails, which would then be 10-ft per county policy. The trail along CSAH 42 is not designated as a regional trail, but the trail is proposed to be 10-ft wide. The city requested 10-ft wide trails be included as 10-ft is the recommended standard for multiuse trails. As a result, the city would pay for the additional 2-ft which results in a 60 percent participation (vs. the 50 percent in the policy).    

The current Preliminary Cost Estimate assumes the city is responsible for 7.5 percent of the roadway improvements within the City of Shakopee. However, the city only has jurisdictional control over land area north of CSAH 42. The area south of the roadway is Shakopee Mdewakanton Sioux Community (SMSC) land in trust. While the city is not indicating that the SMSC should be responsible for that half of the costs, city staff has asked the county to absorb this cost vs. passing it on to the city. City staff will continue to work with the county on an agreeable cost share allocation, which will be presented for future consideration.

City staff has also requested landscaping and trees to be included in the construction plans for certain locations along the trail. In addition to the landscaping and trees that would be included with the project, it is expected that additional boulevard/median/node landscaping and trees will be developed and constructed as part of future land development when it occurs in that area.

City staff concurs with the proposed roadway layout and will continue to work with the county to finalize the cost participation. If City Council agrees, a Cooperative Construction Agreement will be prepared for consideration and approval.
