Problem

In some yards, stormwater runoff can create an area of standing water that lasts for longer than three days. This perennial moisture is often caused by a heavy layer of clay soil and/or a high water table.

Solution

Standing water can be a nuisance, but not necessarily. If the wet area is in a part of your yard that is away and downhill from your house or other structures, go with the flow! Use native wetland plants to filter pollutants from stormwater runoff. Native wetland plants can handle having their roots in standing water for long periods of time. The plant roots will also help to improve soil quality, and therefore infiltration, by helping to break through the heavy clay layer and adding organic matter to the soil which in turn encourages more soil organisms which help to build soil. Many wetland plants are very pretty, and will create a beautiful garden that will attract dragonflies and frogs.
