Authorization To Enter Into Cost Share Agreement With Minnesota Department Of Transportation For Two Roundabouts On County State Aid Highway 86 (280th Street W), County Projects 86-43 And 86-44
end
PURPOSE/ACTION REQUESTED
Authorize entering into an agreement with the Minnesota Department of Transportation (MnDOT) for cost share of two roundabouts on County State Aid Highway (CSAH) 86, County Projects (CPs) 86-43 And 86-44.
SUMMARY
To provide a safe and efficient transportation system, Dakota County is proceeding with CP 86-43 and CP 86-44 to construct rural single-lane roundabouts. County State Aid Highway 86 (280th Street W) is an undivided two-lane rural roadway that is designated as a Tier 2 truck route. This roadway provides regional connection between Trunk Highway 52 and Interstate 35 in Scott County. County Project’s 86-43 and 86-44 will reconstruct two, two-way stop-controlled (TWSC) intersections along CSAH 86 at Trunk Highway (TH) 3 and TH 56 to rural single-lane roundabouts within the townships of Castle Rock, Waterford, Randolph, and Hampton. Construction is scheduled to occur in 2026.
The intersections are listed as priority County/State Highway intersection locations in the adopted Dakota County 2040 Transportation Plan. In 2022, staff applied for and received federal Highway Safety Improvement Program (HSIP) dollars to reconstruct the intersections to single-lane roundabouts. Both intersections have a crash history of primarily right-angle crashes that exceed the state-wide average for similar intersections. As per MnDOT study, roundabouts are proven to reduce fatal and serious injury crashes as well as reduce right angle crashes.
By Resolution No. 24-024 (January 2, 2024), the Dakota County Board of Commissioners authorized execution of a contract with KLJ Engineering, LLC, to perform engineering consulting services in the amount not to exceed $541,313.30. The County will be reimbursed by MnDOT up to a contribution of $300,000, based on invoices submitted for the scope of work. The Capital Improvement Program (CIP) budget reflects a cost share of 50/50 between the County and MnDOT for the consultant services.
RECOMMENDATION
recommendation
Staff recommends the execution of a cost share agreement with MnDOT to reimburse the professional design services invoices not to exceed $300,000 as MnDOT’s share for CPs 86-43 and 86-44 for actual total costs of $541,313.30 for both the projects.

EXPLANATION OF FISCAL/FTE IMPACTS
The adopted 2024 Transportation CIP Budget includes $300,000 for consulting services for CP 86-43 and CP 86-44, totaling $600,000 for both projects. The cost-share for the 2024 design phase is 50 percent State and 50 percent County funds, and a sufficient budget exists under the project numbers to enter into a cost-share agreement with MnDOT.
