The City of Brainerd will stabilize the 1.4-acre gulley that has eroded over 8,706 tons of sediment since 1985. The erosion started after the city constructed a conveyance pipe along Buffalo Hills Lane City Road. The current gully is unstable and poses significant risks to city and public infrastructures, three stormwater outfalls, ten private properties, and houses. Since the 1990s, this gully has transported 100 percent of bank and bed erosion to Little Buffalo Creek and the Mississippi River (HR Green Inc.).
The karst topography of southeast Minnesota increases the possibility of drinking water supplies becoming contaminated with high concentrations of nitrates. To address this risk in the region, there needs to be an increase in the use of nitrogen best management practices and agronomic rates of nitrogen need to be fine-tuned to balance production with environmental degradation. In addition, potential point sources of nutrient contamination in groundwater need to be addressed wherever possible. This project will have three components that will address these needs.
The MWMO , City of Minneapolis and Minneapolis Park & Recreation Board are partnering to implement stormwater projects that reduce pollutant loading to the Mississippi River, reduce flooding and improve ecological function. Three regional Best Management Practices are being proposed in the northern portion of Columbia Golf Course, in Northeast Minneapolis, capturing and treating stormwater from 600-acres of mixed urban landuse.
