How To Stop Backyard Flooding – 6 Smart Ways to Keep Your Garden Soaked Every Time It Rains Avoid water problems in your front, back or side garden by making a few improvements to your landscaping. The following is an article posting created in partnership with Supply House. Here are his facts and opinions.
To mitigate flooding following a rainstorm, today’s subdivisions are designed to facilitate and prevent secondary runoff to safely divert water into the community’s stormwater drainage system. Unfortunately, this isn’t always enough to keep your property from looking a bit swampy after a storm. For example, if your garden isn’t sloped enough to allow rainwater to run through, you may end up with stagnant water that kills your lawn, which is the foundation of your home, and even creates the perfect environment for mosquitoes to breed in. Obviously, it’s a good idea to address drainage issues as soon as possible.
How To Stop Backyard Flooding
If parts of your yard experience frequent rains, try contacting your local zoning and planning authority first. They can help you solve your drainage problem for free. This issue may not be in their jurisdiction, but don’t panic. Homeowners can take steps to reduce local flooding. Daniel O’Brien, a technician at online plumbing retailer SupplyHouse.com, shares drainage and landscaping techniques for reducing flooding and directing water where it needs to go.
Cures For A Waterlogged Lawn
During a rainstorm, rainwater from gutters and downpipes can contribute to flooding if they cannot easily drain your property. The problem may be low spots in the garden or a single point that prevents runoff from flowing into the storm channel. If so, rainwater can be safely diverted through a French drain, which is a perforated underground pipe that collects and diverts surface water.
“French drains provide a relatively simple method of diverting excess water from catchments to curbside manholes,” says O’Brien. The installation consists of digging a trench from the low-lying area to the street and FLEX- Drainage 4-inch x 12-foot Perforated Flexible Pipe (available from SupplyHouse), trenches in a bed of pea gravel. Unlike flexible, rigid pipe, it allows you to customize the drainage configuration so it can maneuver around tree roots or other permanent objects. Once the pipe is in place, it is covered with pea gravel and then covered with soil and grass.
The slope of your garden determines where and how rainwater will flow; this is the most important factor in preventing your garden from flooding. For effective drainage, your yard should have a slope of at least 2 percent away from your house—that is, a drop of two feet for every 100 linear feet of yard.
If your yard does not have a proper slope, water can accumulate in different areas and even along the foundation of your house, causing leaks and serious foundation problems. You can improve the slope by spreading the topsoil along the foundation and in the areas below to facilitate drainage.
How To Prevent Flooding In The Home And Yard
When a patio or sidewalk is located under the surrounding garden, it can become covered with standing water and flooded after a rainstorm.
Raising the surface of a patio or sidewalk is labor-intensive and often costly, but it’s not your only option. “Storm drains offer an increasingly popular method for removing standing water,” says O’Brien. “They are installed along sidewalks or patios, diverting water away from foot traffic.” Franco’s StormDrain Plus Duct with Grate (available from Supply House) should be installed along the lowest slope of the patio or sidewalk where it can connect to a clogged French drain – some concrete lifting may be required to accommodate the duct. discussed above). When it rains, the water flowing to the patio flows from the grate to the gutter and from the French sewer to the easement or pavement. The attractive grate covers found in today’s manhole channels are designed to match your tough look, so your solution will go almost unnoticed.
Flooding near the foundation of your home can be a big problem, especially if you have basement windows and window wells. Because they are located below ground level, they are prime spots for water to collect and inevitably seep into the home.
“Box pumps—especially when equipped with a backup battery—can provide a foolproof method for draining these window wells,” says O’Brien. Install a sump tank with a sump pump, such as the Zoeller Premium Cast Iron Submersible Reservoir Pump (available from SupplyHouse) directly under the window. When the tank is filled with water, the pump runs and pumps the water in and out of the house.
Yard Drainage Problems And Solutions
If the lowlands of your garden are constantly flooded after storms, consider turning these swampy spots into an attractive, all-natural solution to your water woes: rain gardens. Typically, these plant beds fill the soil with porous soil and plants that thrive in stagnant water, such as ferns and Japanese silvergrass.
A rain garden can be as large or small as you need, or it can be custom designed to fix your runoff problems. For a yard with multiple flooded areas, you can build multiple rain gardens or choose to divert water from a low area through a ditch and buried perforated pipe. perforated flexible conduit (available from Supply House) to a single rain garden.
If your property experiences flooding after rain that soaks into the ground relatively quickly (within one to four hours), your garden may be a good candidate for one or more dry wells. Similar to rain gardens, dry wells are placed in low areas to collect water but are not used for growing plants, excess water is stored in buried tanks and then slowly seeps into the surrounding soil. There is a grate on the top of the tank through which water can enter, and the homeowner can control the water level below.
You can choose to install a dry well in the flow path of each downpipe. Alternatively, you can carry water into a dry well using a pressed French drain and perforated pipe, such as FLEX-Drain 4-inch x 12-foot perforated flexible pipe (available from Supply House).

Check your rain gutters to see if they are clogged. Ideally, you should clean your gutters regularly, twice a year. Spring and autumn are the best times for this.
A downpipe or drainpipe is a pipe that connects to the gutter and the side of your house. The main purpose of this pipe is to convey the water coming from the rain gutter to the soil. A good and properly installed drain pipe prevents water from splashing onto building structures or accumulating on the ground.
One of the main causes of backyard flooding is when there are too few downpipes. Extend at least 3 feet with it and direct the water away from the garden and the foundation of your house.
Many homes have sump pumps whose primary purpose is to prevent water from pooling in the basement. Check your sump pump regularly to see where it is draining. If necessary, attach an extension to it and divert water away from your garden.

According to experts, the ideal minimum slope for your lawn should be 2 to 3 inches for every 10 feet from the foundation. This accounts for about 2 percent of the minimum slope, while the maximum slope should be 12 inches per 4 feet, or about 25 percent.
Large-sized barrels that are kept under the ground during rain are called rain barrels. In case of heavy rain they can be placed under the drainage pipes.
