Standing water can make it difficult to enjoy your yard after a heavy rainfall. Lawn areas can become muddy, water can erode the landscape, and excess runoff can travel toward your home.
For families with children and pets, poor drainage can also mean waiting longer for outdoor spaces to dry before you can use them again. The right drainage solution depends on where the water is coming from, how it moves across the property, and where it needs to go. Here are four landscape drainage solutions that can help manage excess water and create a more functional outdoor space. Start by Identifying the Source of the Water
Before installing a drainage system, it is important to understand why water is collecting in the first place.
Because every property has different grades, water sources, and landscape conditions, the appropriate drainage solution will vary from yard to yard. 1. Route Downspouts Away From Your Home
One of the first places to look when addressing yard drainage is the home's downspouts.
Gutters collect rainwater from the roof and direct it into downspouts. The volume involved is larger than most homeowners expect. A single inch of rain falling on 1,000 square feet of roof produces roughly 620 gallons of water, which means a significant storm can discharge hundreds of gallons around the base of the home. When downspouts release that water directly beside the foundation, it can collect around the house or travel across the lawn. How Downspout Routing Works An underground drainage pipe can connect to the downspout and route water away from the home. A 4-inch corrugated drainpipe carries water underground downhill and discharges it beyond the property's usable space. The pipe needs consistent fall along its entire run—generally a minimum of about one inch of drop for every eight feet of pipe—so gravity keeps water moving rather than allowing it to sit in low spots along the line. Properly routing downspouts can help:
2. Install a French Drain
French drains are another option for areas that consistently stay wet or don't drain properly.
Installed below the surface of the landscape, French drains can be placed beneath lawns or landscape beds. Once the project is complete, the drainage system is generally hidden from view. How a French Drain Is Built A French drain is a sloped trench that intercepts water along its length and carries it to an outlet. A properly built system includes four components:
The fabric is what determines how long the system lasts. Without a geotextile filter, soil and silt gradually migrate into the stone and clog the perforations in the pipe. A drain installed without fabric can lose most of its capacity within a few years, even though nothing is visible at the surface. It is one of the most common shortcuts in residential drainage work and one of the most common reasons a drain stops working.
A properly installed French drain can help:
3. Redirect Surface Water With a Berm
Not every drainage problem requires an underground drainage system.
When water flows onto a property from a neighboring property, driveway, or surrounding area, changing the landscape's grade can help redirect it. A berm is a raised and contoured area of landscape positioned to redirect surface water away from lawns, landscape beds, or the home. Depending on the application, berms generally range from about 10 to 24 inches in height and may extend several feet in width. The berm is set at an angle to the incoming water so that runoff is guided around the usable portion of the property rather than through it. Berms Can Be Both Functional and Attractive Berms can be incorporated into the landscape with plants and other features, allowing them to serve two purposes:
4. Add a Dry Well or Stone Collection Basin
Properties that receive significant amounts of runoff may need a larger collection area to manage the water effectively.
This is where the small 12-inch by 12-inch plastic catch basins commonly installed in yards tend to fall short. They are often asked to handle far more water than their collection capacity allows, which limits both their effectiveness and their longevity. For high-volume situations, we build a larger stone collection area below grade instead. How is this different from a French drain? The two share similar materials, but they do different jobs. A French drain is long and narrow, designed to intercept water gradually along its length. A collection basin is wider and built to hold and process a large volume of water arriving at one location — the bottom of a slope, or the discharge point where several downspouts converge. How Stone Collection Basins Work
The collection area is excavated to a depth of roughly 2 feet, with the length determined by the site's drainage needs. The general process includes:
Don't Overlook Where the Water Ends Up
Every drainage system needs somewhere to discharge, and the outlet deserves as much thought as the collection point. A system that moves water off one part of a property and concentrates it at the property line moves the problem rather than solving it.
A well-planned outlet releases water at or near the property's natural low point, disperses it rather than concentrating it, and accounts for the grade of surrounding properties. Some neighborhoods also have covenants or local stormwater requirements that affect how drainage water can be handled. Identifying an appropriate discharge point is part of evaluating the site, not an afterthought once the trench is dug. How to Choose the Right Yard Drainage Solution
In many cases, more than one drainage method is appropriate. Common combinations include routed downspouts feeding into a collection basin or a berm paired with a French drain.
A drainage plan should consider the property's grade, water source, lawn, landscape, and the outdoor areas affected by excess water. Improve Your Yard's Drainage and Protect Your Outdoor Space
Effective landscape drainage is about more than eliminating a puddle in the yard.
A well-planned drainage system can help protect your home's foundation and landscape while reducing erosion, mud, and standing water. It can also help outdoor areas dry more quickly, allowing families and pets to get back outside sooner after rainfall. Landscape Logic has been creating drainage solutions for residential and commercial landscapes in Chapel Hill, Durham, and the surrounding Triangle area for more than 30 years. Rather than applying the same drainage solution to every property, we evaluate the site and determine the right combination of drainage methods. If your yard stays wet after rainfall or you have recurring standing water, a property evaluation can help identify the source of the problem and determine an appropriate solution.
