Take care of roof runoff
While water coming directly off the roof is relatively clean, it builds up enough volume and velocity to immediately erode the soil as soon as it touches the ground. Using dry wells, drip edge drains, rain gardens or rain barrels can alleviate erosion caused from roof runoff and reduce your home's overall environmental footprint. This rain garden at the Portland Water District’s Lake Office in Standish is an attractive way to treat roof runoff.
