Landscape Drainage Solutions to Help Problem Areas
We get our fair share of rain in the Pacific Northwest, so it’s not uncommon to have some landscape drainage issues. Adding a rain garden or a dry creek bed are great drainage solutions that can even enhance the look of your landscape.
Water drainage problems in your yard decrease property value and can lead to costly water damage to your house and other structures, as well as plant and turf damage. With a little planning, you can alleviate your drainage issues to protect not only your yard but also your home.
How to Check Your Yard for Drainage Issues
Pay attention to where the trouble spots are in your yard. Are there slopes that could be leveled out, mulched, or other materials added for draining? Is there an area with runoff from the driveway or gutters?
To get a rough idea of where the problems lie, take advantage of heavy rains to watch what happens to the water. Does it gush from the gutter and flood your flower bed or pool below your deck? Is there an area in your yard that becomes a swamp – or that remains swampy all year? Lawns and plants will die and/or become susceptible to disease and pest problems if they’re not able to dry out.
Does water run across the driveway or into the street during a hard rain or, worse yet, soak areas around your home’s foundation? In some cases, the grade was not established correctly and did not take into account that the ground should slope down and away from the house.
Level a sloping yard. To avoid incoming water, the ground should always slope away from your home in all directions. Locate the high and low points of your home and use extra soil to slope the yard away from your house. Melting snow and rain will flow away from your home.
Landscape Drainage Solutions
Choose native plants that prevent flooding in your yard. Native plants can help to prevent soil erosion while also allowing rainwater to drain more efficiently. Some selections for our area are Slough Sedge, Western Columbine, and Pacific Ninebark.
Using mulch in your garden can prevent water from flowing toward your home. In garden areas, grade away from your home and fill with a few inches of mulch. This will help keep soil in place and hold in rainwater. If mulching near your home, make sure the mulch is at least six inches from your siding to avoid moisture wicking and rotting of your home’s exterior.
Consider planting a rain garden. Rain gardens are the perfect solution for curbing erosion and improving water quality. They collect rainwater and water that runs from your gutters and downspouts, creating runoff and filtering it away from your house. They are often created in shallow, landscaped depressions, which helps to naturally absorb rainwater in the ground.
Dry Creek Bed
Install a dry creek bed to provide attractive and functional relief, especially if your landscape has standing water.
Dry creek beds are an excellent choice for addressing places in the landscape that are hard-hit by heavy rains. While a flat place in the yard may benefit more from a simple lawn drain, gradients and hillsides need the water capacity and speed that a dry creek bed can provide during extreme conditions. This drainage solution can be a nice addition to the look of your landscape by using different-sized rocks, boulders, and plantings.
French drains are the most commonly used means of collecting, conducting, and discharging water. This is a trench filled with gravel, sand, or rock (depending on application) and containing a perforated pipe that redirects surface water and groundwater away from an area. The perforated (“weeping”) pipe also allows small amounts to seep into the ground along the way.
