Too much rain can undermine a home, but a rain garden will easily solve the problem. The rain garden is planted with special deep rooted species of plants that help the water rapidly seep into the soil. The rainwater flows from the downspout and is directed away from the house and out of the lawn via a swale/stone channel. The garden bed captures the water and drains into the soil quickly.
An added advantage is mosquitoes won't have time to breed, because the water drains within a day. This also reduces the load on the sewer system, and the amount of lawn chemicals and pet wastes that would otherwise have drained into the sewer system making its way to rivers and lakes.
