PURPOSE/ACTION REQUESTED
Authorize execution of the third contract amendment with Toltz, King, Duvall, Anderson, and Associates, Inc., for continuing preliminary engineering services for County State Aid Highway (CSAH) 46 in the cities of Rosemount, Empire, and Coates, County Project (CP) 99-013 (ST00011).
SUMMARY
Dakota County and the cities of Rosemount, Coates, Empire are partnering on CP 99-013 (ST00011) to support the development of a safe and efficient transportation corridor. The project includes the preliminary design of CSAH 46 (160th Street/Brandel Drive) from Trunk Highway (TH) 3 in Rosemount and Empire Township to CSAH 48 (160th Street) in Coates (Attachment: Project Location Map). The design effort includes evaluating expansion to a four-lane divided highway, reviewing existing right of way, and establishing preliminary right of way limits.
Previous Authorizations
• by Resolution No. 24-090 (February 27, 2024) approved the original design contract with Toltz, King, Duvall, Anderson, and Associates, Inc.
• Administrative Change (December 2024) approved the first amendment extending the contract through December 31, 2025.
• Administrative Change (December 2025) approved the second amendment extending the contract through December 31, 2026.
Need for Third Amendment
The original scope included development of the County’s preferred layout for CSAH 46 expansion and preparation of the Minnesota Department of Transportation (MnDOT) Level 1 layout for improvements to the TH 52 interchange ramps.
During project development, the University of Minnesota’s planning team raised concerns regarding safe crossing and turning movements for slow-moving agricultural equipment at Akron Avenue and Barbara Avenue. Although traffic signal warrants are not met, the University indicated that the combination of heavy agricultural traffic and mining operations will continue to pose safety challenges on a future four-lane CSAH 46. This feedback requires the County to evaluate additional intersection alternatives at Akron Avenue and Barbara Avenue to identify feasible solutions.
The County has secured a $3.85 million 2025 Transportation Economic Development Grant and $10 million from the Federal Regional Solicitation for improvements at the TH 52/CSAH 46 interchange. Expediting the MnDOT Level 1 layout process is necessary to maintain progress and support timely advancement toward final design and construction.
These additional needs increase both the duration and complexity of the project. The negotiated cost for completing these tasks is $112,562, which exceeds the current contract amount of $452,790.75 (Attachment: Additional Tasks Justification).
The need for an amendment arises due to additional tasks that have been identified as essential for the successful completion of the project. These tasks include:
1. Corridor Layout Alternatives at Akron Intersection - $19,333
2. Corridor Layout Alternatives at Barbara Intersection - $10,674
3. MnDOT Level 1 Geometric Layout approval - $20,064
4. Updating Traffic Analysis - $19,961
5. Updating Drainage Design - $10,356
6. Enhanced Stakeholder/Agency Coordination - $7,614
7. Supplementary Project Management Tasks - $24,560
Total - $112,562
RECOMMENDATION
recommendation
Staff recommends authorizing the third contract amendment with Toltz, King, Duvall, Anderson, and Associates, Inc., for additional preliminary engineering services, for an amended contract value not to exceed $565,352.75.
