St. Mary's Greek Orthodox Church
In 2010 the MCWD helped fund construction of permeable pavers with infiltration tanks and bio-retention basins at St. Mary’s Greek Orthodox Church.
STORMWATER MANAGEMENT BMPs
- Existing flat rooftops for detention
- Five subsurface ‘soy based’ plastic storage chambers
- One subsurface corrugated metal storage reservoir
- One infiltration basin w/turf
- One detention basin w/turf
- Five bio-retention basins w/rain garden plants
- 3,550 square feet of permeable pavers
WATER QUALITY AND VOLUME CONTROL
This multi-prong approach significantly reduced the amount of phosphorus pollution in Lake Calhoun. By reducing the amount of impervious surface, adding water-friendly landscaping, and increasing stormwater infiltration capacity, the project reduced the amount of phosphorus going into the lake by about 30 percent.
From Stormwater Magazine:
St. Mary’s Greek Orthodox Church sits above the shore of Lake Calhoun in the Minneapolis suburb of East Calhoun. Runoff from the church’s parking lot and property carried pollutants directly into the lake.
