Last year the Shingle Creek Commission, City of Robbinsdale, and Hennepin County Environmental Services partnered on an intensive BMP study for the Crystal Lake subwatershed in Robbinsdale. The study identified a number of small BMPs that could be implemented, each achieving a small phosphorus and sediment load reduction, and some an additional volume reduction. The projects are described on the Robbinsdale BMP page.
The Minnesota Chapter of the American Public Works Association (APWA) has nominated the Shingle Creek Porous Pavement Paired Intersection Study for the national APWA Excellence in Snow and Ice Control Award. This study is being completed by the Shingle Creek Watershed Management Commission and the City of Robbinsdale, and is funded by an EPA grant administered by the Minnesota Pollution Control Agency. Porous asphalt is a special mix designed to let water pass through the pavement into a gravel bed below the pavement. The research study is evaluating whether porous asphalt can work as well for winter snow and ice control as using road salt. Shingle Creek contains high concentrations of chloride, which comes from road salt, or sodium chloride. Snow and ice melting on porous asphalt infiltrates through the pavement and does not freeze on the surface. If less ice builds up, then less salt needs to be applied to the road and less washes off into Shingle Creek and our other lakes and streams.
