Why a Rain Garden?

By Cauleen Viscoff, Lindsay Master Gardener

In the forest, a raindrop’s journey is long; from cloud to creek; intercepted by trees and vegetation before it soaks into the ground-less than 10% runs off into rivers and streams
In the city, its a fast ride; on the roof, down a spout onto a driveway, onto the street and down the storm drain.pavers-2946486__340

When a forest becomes a city, more than 50% of rainfall meets impervious surfaces -roads, buildings, parking lots; the rain becomes stormwater, filled with polluted urban waste; fertilizer, animal waste, oil, heavy metals, road salt, cigarette butts, etc.It causes erosion, flooding, (over $1 billion in flood-related insurance in past 6  years). Stormwater is the leading cause of poor water quality.

Every time you press your car’s brakes, cadmium and zinc are released onto the road; and every pound of leaves left on the street, contains enough phosphorous to bloom up to 10 pounds of algae (if allowed into the storm drain).

What can we do?

Manage rain where it falls.
SOAK IT UP – porous pavers, grass and gardens
SLOW IT DOWN – rain barrels, downspouts into garden – keep away from foundation and out of storm drain
KEEP IT CLEAN  – rain garden – filters rain water, slows it down, soaks it up and keeps it clean.

A rain garden is easy, simple and best in a low spot where rain naturally runs off. Use plants with spreading roots. Find out how to here:
