• -Rain Garden-
• Collects runoff from roof and yard, keeping it
  out of stormwater drainage system.
• Allows pollutants to be filtered out and
  decreases localized flooding.

14

• Unlike bog or wetland gardens, Rain Gardens hold
  water for only 1 to 2 days.
• Compared to a conventional lawn, a Rain Garden
  can allow 30 more water to soak into the ground.
  Rain Gardens are also wonderful habitat for
  wildlife and can be an attractive asset to any
  property.
