TKDA played a major role in designing a safer interchange
In an effort to improve safety and reduce crashes, Dakota County and MnDOT cooperated on the design and construction of a grade-separated interchange at TH 52 and CSAH 86. TKDA was hired to lead the preliminary design phase of this project.
TKDA’s preliminary drainage design included existing and proposed condition HydroCAD modeling, floodplain mitigation design, and the preliminary culvert layout. TKDA also provided infiltration basin design to meet NPDES permit requirements for discharge to a trout stream and permitting for wetland impacts.
