Rain gardens are shallow depressions that collect and absorb stormwater from roofs, driveways, compacted lawns, etc. This is important because a typical Eagan home and yard may shed 7,000 gallons of water during a 1" rain storm. Every home has an impact on stormwater runoff. Planted with shrubs and perennials, rain gardens infiltrate water into the ground. Rapid absorption (2 days or less) prevents standing water and breeding sites for mosquitoes. They are also a beautiful and colorful way for homeowners to do their part to protect our lakes and wetlands.
Find the right place
Effective rain gardens are near a source of runoff. Map your yard and go outside when raining to observe water flows. Rain gardens should be at least 10’ from the foundation and down-slope from the house.
Determine the right size
The basin should be about 10% of the area that drains to it.
Locate buried utilities before you dig
State law requires contacting Gopher State One Call at 811; (651) 454-0002; or www.gopherstateonecall.org at least 2 working days before digging, to locate buried utilities (natural gas, electric, cable, etc.).
