One of the projects overseen by the MPCA was the construction of the Maplewood Mall stormwater system, which will contribute to the improvement in Kohlmann Lake’s water quality by preventing 50 pounds of phosphorus and five tons of sediment per year from entering the lake.
Some of the most innovative engineering projects undertaken in Minnesota in 2012 were set into motion as a result of environmental initiatives undertaken by the Minnesota Pollution Control Agency.
The American Council of Engineering Companies of Minnesota (ACEC/MN) recently announced the winners of its 2013 Engineering Excellence awards. Several of the 29 award-winning projects were set into motion as a result of environmental initiatives undertaken by the Minnesota Pollution Control Agency.
The projects represent some of the most innovative engineering work undertaken in Minnesota in 2012. Some were directly funded or overseen by MPCA; others were initiated in response to the agency’s environmental work. Three of these environmental projects will compete for recognition at the national level.
One of the award-winning projects converted an Edina parking garage into a new drinking water treatment plant. When it was discovered that the city’s groundwater was contaminated with vinyl chloride, a new treatment system was needed to protect the quality of the water supply.
The MPCA provided financial support for the project’s design, while the city funded construction and ongoing operation of the facility. The unique project, designed by the engineering firm AECOM, allowed the city to reuse an existing structure. This eliminated the need to use valuable green space for infrastructure improvements.
Another project recognized by ACEC/MN was an innovative stormwater management system at Maplewood Mall. The system, designed by Barr Engineering, will capture and treat 90% of the stormwater runoff at the site. It incorporates rain gardens, permeable pavement crosswalks, a cistern that captures roof runoff for irrigation, and some 200 trees.
