Right As Rain Gardens
By controlling the flow of water from summer storms, you can use it to beautify your landscape.
Rain gardens are designed to collect and filter storm-water runoff from surfaces such as roofs, driveways, parking lots and roadways. Consisting of swales planted with woody and herbaceous plants that tolerate both periodic flooding and extended dry periods, these gardens act as artificial wetlands. The plants absorb much of the storm water and the remainder percolates into the soil.
The EPA has determined that up to 70 percent of the pollution in our surface waters is carried to waterways by storm-water runoff. Many studies have shown that the aggregate of non-point sources, such as residential and commercial landscapes with their over-fertilized and poisoned lawns and runoff from driveways and parking lots, may cause more problems than large industrial polluters.
