Abstract:

The project discussed below is part of a critical inter-regional transportation corridor located in central Minnesota. The roadway currently exists as a 2-lane trunk highway and is being reconstructed into a 4-lane, divided highway with associated service roads. The project is a major land use feature in the watershed of several recreational lakes as well as watersheds for multiple wetland systems. Because of the importance of the lakes and wetlands to the economy of the region, three state agencies, the Minnesota Department of Transportation (Mn/DOT), the Minnesota Pollution Control Agency (MPCA) and the Minnesota Department of Natural Resources (MDNR) prepared a interagency agreement which set forth as a goal the achievement of no net increase in the loading of pollutants from the new roadway construction. The main focus of this paper is the use of a technical and citizens committees to screen a large number of best management practices to achieve the stated goal. The primary pollutants of concerns include:



Total Phosphorus


Total Suspended Solids
