Authorization To Execute Cooperative Construction Agreement With Minnesota Department Of Transportation For Two Roundabouts On County State Aid Highway 86, County Projects 86-043 And 86-044
end
PURPOSE/ACTION REQUESTED
Authorize execution of Cooperative Construction Agreement No. 1060218 with the Minnesota Department of Transportation (MnDOT) for two roundabouts on County State Aid Highway (CSAH) 86 at Trunk Highway (TH) 56 and at TH 3, County Project (CP) 86-043, and CP 86-044.
SUMMARY
To provide a safe and efficient transportation system, Dakota County is proceeding with CP 86-043 and CP 86-044 to construct two 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 a regional connection between TH 52 and Interstate 35 in Scott County. County Project’s 86-043 and 86-044 will reconstruct the two two-way stop-controlled (TWSC) intersections along CSAH 86 at TH 56 and TH 3 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 Highway/State Highway intersection locations in the adopted Dakota County 2040 Transportation Plan. In 2022, staff applied for and received Highway Safety Improvement Program (HSIP) federal dollars for the reconstruction of the deficient intersections.
The terms of the agreement include the survival of the terms, plans, incorporation of exhibits, and the effective date. This agreement will be effective when the State obtains all signatures required by Minn. Stat. § 16C.05. This Agreement will expire when all obligations have been satisfactorily fulfilled. The survival of terms is defined as follows: all clauses that impose obligations continuing in their nature and must survive to give effect to their meaning will survive the expiration or termination of this agreement. The terms and conditions outlined in signal systems and Emergency Vehicle Preemption (EVP) systems, as well as operation and maintenance, will survive the expiration of this agreement but may be terminated by another agreement between the parties.
Executing MnDOT Cooperative Construction Agreement No. 1057369 will establish cost-sharing and update the maintenance, operation, and power responsibilities for the two roundabouts.
The Agreement will allow the construction of grading, bituminous surfacing, and Americans with Disabilities Act improvements. The State will grant the County (and its contractors and consultants) the right to occupy the TH right of way as necessary to perform the work described in the Project Plans. The Agreement will also define maintenance, and operation responsibilities for the two roundabouts.
RECOMMENDATION
recommendation
Staff recommends executing Cooperative Construction Agreement No. 1060218 with MnDOT for construction, maintenance, and operations of two roundabouts at CSAH 86, CP 86-043 and CP 86-044.
