These green initiatives show how everyone can make a difference to improve the water quality of our lakes, creeks and the Mississippi River. Every time it rains, you water your lawn or wash your car, stormwater carries pollutants into the City’s storm drain system.
Building green roofs creates healthier and more efficient buildings, providing great environmental, economic and social benefits.
Planting trees helps retain rainwater on a tree's leaves & trunk, resulting in reduced stormwater runoff. Trees also soak up water in the soils through their roots, allowing soil more time & holding capacity for filtration.
Trees retain water and slow stormwater runoff, reducing the intensity of downstream flooding.
Rain gardens reduce the amount of stormwater and pollutants entering the Mississippi River, and the lakes and creeks of Minneapolis. Direct the rain from your roof or driveway to a rain garden and keep that rain on your property, instead of going into the storm drain system.
Rain gardens containing native plants can survive varying wet and dry conditions, and have a deep root system that helps improve soil conditions.
Native plants in rain gardens have deep root systems which can survive both wet and dry conditions, and they help improve soil conditions.
A 1" rain storm produces 600 gallons of stormwater runoff from a roof surface of 1,000 sq.ft. That runoff contains pollutants which empty into storm drains, before discharging into the waters of Minneapolis.
Rain barrels help by trapping some of this stormwater runoff, and also help conserve water.
Urban areas contains an abundance of hard, or impervious, surfaces. Pervious pavement allows stormwater runoff to infiltrate into the ground, keeping this water out of the Mississippi River, and the lakes and creeks of Minneapolis.
