Retaining Wall or Regrade? Best Fix for a Steep, Eroding Yard in WV
A steep yard can be beautiful until the rain starts moving it.
At first it doesn't seem like much, but a little dirt runs off the edge of the yard, the mulch moves downhill, small channels form where the water runs consistently after each storm, and the grass starts thinning out, sloping becomes harder to mow and the same areas keep getting worse.
That is usually when homeowners wonder if they need a retaining wall.
Sometimes the answer is yes; sometimes a retaining wall can be the right fix for soil that needs substantial support or where there isn't room to regrade a slope.
But sometimes a retaining wall isn't the first thing such a property needs, and the better fix may be regrading, or a swale, riprap, or drainage pipe or outlet, or a combination of things. In most cases, the first order of business is not to pick a product but understand where the water is going.
Around Beckley, Glen Daniel, Raleigh County, and the surrounding Southern WV
region steep yards are abundant, as are clay soil, runoff, softer ground, older
drain paths, and slopes that have been gradually changing
Built Right Construction Inc. provides excavation, grading, drainage, driveway,
septic, culvert, and site preparation throughout Southern WV. When your yard
begins to erode, here's what you need to consider when weighing options such as
retaining walls, regrading, or other drainage corrections.
Start with the water, not the wall
A retaining wall holds back soil.
It doesn't necessarily address water, which is why many homeowners don't hear
the warning until a wall they've built has already begun to lean, settle, or crack. If
runoff is continuing down a slope behind a wall, the wall may only be a partial fix
for a larger issue
The EPA explains stormwater runoff as rain or snowmelt that runs over the land or
an impervious surface rather than infiltrating the ground. Uncontrolled runoff can
lead to soil erosion
That erosion on a steep WV yard may be your topsoil, mulch, gravel, or driveway
base washing away, one storm at a time
Before choosing a retaining wall, consider where the water originates, and if it is
coming from uphill, or down the driveway, or if a downspout is dumping into a
slope, or if a ditch is overflowing, or your yard is draining toward the house, those
are important factors.
When regrading may be the better fix
Regrading can help redirect the flow of water
If the slope can be softened, blended, or bent into a new direction without
retaining a large amount of soil, regrading may be a more cost-effective option
to walls.
It may help if
• water is moving toward the house
• shallow channels form in the yard
• low spots fill with water
• the driveway shoulder is eroding
• the yard or slope needs to be redirected
• the slope is uneven but not sliding
• the yard needs a surface drainage path
The aim is not to make the yard or slope pretty but to assist it with shedding
water without allowing it to dig into the slope.
Water moving toward the house is a good starting point. This guide on Signs You
Need Regrading Around Your Home in West Virginia can help you recognize other
issues.
When a swale may be the right answer
A swale is a shallow drainage path carved into the ground
It can intercept water before it reaches an undesirable area and lead it
somewhere else, which is helpful on a steep yard.
A swale doesn't have to look like a ditch; it can be subtle and blend into the yard
while still guiding water around the house, away from the driveway, or toward a
stable outlet.
Stormwater Control that swales, drains, and site grading can be used to control
and remove stormwater from a site
A swale may be a good option if there's surface water to be collected, and
enough slope to carry it to a stable outlet.
The outlet is the big thing, as you don't want to push the water into another
unstable place. Avoiding the septic area, the driveway, the neighbor's property, or
a soft spot that will begin eroding are all important factors. For a deeper
comparison, see Swale, French Drain, or Catch Basin? Picking the Right Drainage
When riprap or stone protection may be needed
Some slopes require more than being reshaped but need to be protected as well
If water is exiting a culvert, running in a ditch, or following a channel on a regular basis, bare ground may not be the best option. That's where stone protection can help.
Riprap can help with:
• Culvert outlets
• Ditch outlets
• Steep drainage paths
• Eroding yard edges
• Concentrated runoff areas
• Areas where the soil is washing away
But riprap should not be used as a random patch. If water is not controlled, it may
begin to erode around or under the riprap. Stone works best when the grade,
water path, and outlet are considered together.
If erosion has already begun, see Erosion Control for WV Properties for more on
swales, riprap, grading, and drainage strategies.
When a retaining wall may actually be needed
A retaining wall may be right for soil that needs to be held back, or a slope that
needs to be held in place.
It may be necessary if the slope can't be reshaped, the soil is sliding, or there's not
enough room to regrade the area, or you need a flat driveway, yard, patio,
building pad, or walkway.
A retaining wall may be necessary if
• the slope can't be reshaped
• soil is sliding or slumping
• a flat area is needed
• the slope drops dangerously near a home or driveway
• regrading would be too space-consuming
• the slope needs structural support
A wall can be a good solution, but it has to be built with drainage in mind.
Water behind a retaining wall builds up and has to have an escape, and if it
doesn't, it can cause walls to lean, crack, settle, and fail.
Why drainage behind a wall matters
The soil behind a retaining wall is still going to get wet
That water has to go somewhere, and depending on the wall and the layout, the
proper drainage may include some stone backfill, pipe, filter fabric, weep paths,
and a safe outlet. That hidden drainage is important to the longevity of the wall.
That is why a retaining wall shouldn't be treated as simple landscaping if it's
holding back soil on a WV slope.
The wall itself is only one aspect of the job, and the water behind it is a crucial
part.
When a French drain or catch basin may help
Not all slope issues are on the surface, and not all issues are resolved by
removing surface water
If the ground is consistently moist below the surface, a French drain can help
collect and remove it. If there are areas where the water pools before flowing
downhill, a catch basin can help collect it and move it through a pipe.
But both need an outlet. A buried drain with nowhere to discharge won't do much
for the water, and for your yard.
If your yard is consistently wet after rain, see Why Your Yard Stays Soggy in WV,
which explains how clay, low spots, runoff, and grading can all contribute to a
soggy yard.
What not to do with a steep eroding yard
Don't build a wall before you understand the water
Don't dump gravel into an erosion channel and expect it to hold
Don't pile soil on a steep slope without stabilizing it
Don't send water toward the house, septic area, driveway, or neighbor's property
Don't ignore small channels forming in the lawn
Don't assume a French drain fixes every slope issue
Don't wait until erosion reaches the driveway or foundation
Most issues with steep yards get worse because the water continues using the
same weak path.
Cost factors for fixing a steep eroding yard
The slope, soil, and water volume can all affect the cost
Common factors include:
• The size of the area
• Steepness
• How much grading is needed
• The soil and ground conditions
• Access to the area
• The need for swales or ditches
• The need for riprap or stone protection
• The need for French drains or catch basins
• The need for a retaining wall
• Drainage behind or around the wall
• Outlet protection
• Seeding, stabilization, and cleanup
The difference between a simple regrading job and a retaining wall could be
steep. The slope with active erosion, poor access, and drainage may need a more
involved plan.
The best value usually addresses both the soil and the water.
What to expect when Built Right looks at a steep yard
When we evaluate a steep, eroding yard, we do not assume you need a wall
We consider where the water originates, how it moves across the slope, where the
soil fails, and where water can be directed. We look at the house, driveway, septic
area, ditches, culverts, and outlets. And sometimes the answer is a regrading job,
or a swale, riprap, drainage pipe, catch basin, or a retaining wall. Sometimes it's a
combination
The aim is to stop the erosion in a way that works for the property and holds up
through Southern WV weather.
FAQ: Retaining wall or regrade for a steep WV yard
Do I need a retaining wall for an eroding yard?
Not necessarily. If the issue is surface water, regrading, swales, or erosion control
may help. A retaining wall is usually considered when soil needs structural
support or the slope cannot be reshaped.
Can regrading fix a steep yard?
Sometimes. Regrading can help if the slope can be reshaped and water can be
redirected safely. If the slope is too steep or unstable, more support may be
needed.
Why does water keep cutting channels in my yard?
Water takes the easiest downhill route. Once a small channel forms, each storm
sends more water through it, deepening it over time.
Does a retaining wall need drainage?
Yes. Retaining walls that hold back soil usually need to have drainage planning
because water pressure behind the wall can cause problems.
Is riprap better than a retaining wall?
Riprap protects soil from moving water. A retaining wall holds up soil. The right
solution depends on whether the issue is erosion from runoff or the slope needs
support.
Can drainage work protect my driveway too?
Yes. If the steep yard sends water toward the driveway, drainage corrections can
help prevent washouts, ruts, and soft spots.
