The reconstruction of the St. Croix Trail (Country Road 21) and Afton Boulevard/Stagecoach Trail (County Road 18) in the City of Afton included a levee reroute/reconstruction and the redesign/ reconstruction of all local streets Afton’s “Old Village”.
A new sanitary sewer collection system and lift stations were designed and constructed to allow for removal of septic drain fields from the levee. The new design will prevent the continual discharge of septic effluent into Lake St. Croix. To further eliminate potential pollutants to Lake St. Croix, all storm water will be treated when passing through the “Old Village” and county roads beyond the reconstruction limits. The treatment will maximize pollutant removal before stormwater enters Lake St. Croix.
