These raingardens may seem small but their impact on water quality is incredibly important. Below, we have estimated the amount of runoff that each raingarden captures per year, and as a group of 8 raingardens. Take that water quality benefit and multiply it over many years, not to mention the pollinator habitat created by the new native plants. A total of 349 new native perennials and shrubs were planted as a part of this project. The impact is huge and very exciting!
Metro Blooms installed 8 raingardens in the Logan Park neighborhood in the summer of 2019.
Total Project square footage: 916 sf
Each raingarden was an average of 114 sf.
Pollution Reduction Calculations per raingarden per year (estimated):
Runoff captured – 14,744 gallons
Total Suspended Solids captured – 6.7 lbs.
Total Phosphorus captured – 0.037 lbs.
Pollution Reduction Calculations for total project per year (estimated);
Runoff captured – 117,952 gallons
Total Suspended Solids captured – 53.5
