13- -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.
