Yard Erosion Control in Lancaster, PA

Yard erosion control stops runoff from carrying soil away from slopes, garden beds and the ground around your foundation. It is for Lancaster homeowners who see gullies, bare patches, exposed roots or soil thinning beside the house. We find where the water is coming from, then slow it, spread it or send it somewhere it cannot do damage.

What yard erosion control involves

Erosion is moving water picking up soil and carrying it off. It happens when more water arrives than the ground can absorb, or when water runs fast enough over bare soil to lift it. Erosion control is the work of cutting the speed and volume of that water, and then covering or holding the soil that is left.

This page is about that one problem: soil leaving. If you want the wider picture of how water should move across your lot, start with Yard Drainage. Here we stay with washouts, slopes and the soil that matters most, the soil next to your house.

Signs that runoff is eroding your yard

Erosion rarely starts as a dramatic washout. It usually starts small and gets worse with each hard rain, so the early signs are worth taking seriously.

Rills and gullies

Rills are thin channels, a finger or two wide, cut into bare soil. Left alone, runoff finds them every time and deepens them into gullies that can swallow a mower wheel. A gully usually follows the same path water takes on every storm, which tells us exactly where to work.

Exposed roots and bare patches

Tree roots standing up out of the ground, grass that never fills in on a slope, and a crust of fine silt or sand on the surface all point to topsoil moving. The heavy particles stay behind and the fines wash away, so the soil gets poorer as well as thinner.

Washed-out mulch and beds

If your mulch ends up on the lawn or the driveway after rain, or plants sit higher than they used to, water is crossing the bed instead of soaking into it. A new layer of mulch will not fix that. It will wash out again.

Soil loss at the foundation

This is the one that cannot wait. When soil drops away from the foundation wall, the ground no longer slopes away from the house. Rain then runs toward the wall and into the soil beside it, which is how a small erosion problem turns into a wet basement.

Erosion control methods we use

No single fix suits every yard. The right method depends on how steep the ground is, how much water crosses it and what is growing there.

Cutting the water off at the top

The cheapest erosion control is keeping water from reaching the slope in the first place. A shallow, grassed drainage swale above a bank can pick up runoff and carry it around the weak ground at a gentle pace. Where the ground is too flat or too tight for a swale, a buried pipe or a short channel does the same job.

Fixing roof water

Downspouts that empty onto bare ground beside the house are one of the most common causes of erosion near a foundation. A spout can drop a large volume of water in one spot during a storm. Extending it through solid pipe to a safe outlet often stops the damage on its own. We cover this in more detail under downspout drainage.

Slowing water with stone

Where water has to run down a slope, a lined path keeps it from digging. That can mean a channel of angular rock over filter fabric, small rock check dams spaced down a ditch, or a stone apron at a pipe outlet so the water spreads out instead of drilling a hole. The stone breaks up the energy of the flow, and the fabric stops soil from washing out from underneath.

Holding the soil that remains

Once the water is under control, bare ground needs cover. On steeper banks we use straw or coir erosion blankets pinned over seed, which hold the soil while roots take hold. On very steep or high-traffic ground, a low retaining wall or a planted bank of deep-rooted groundcover may be the better answer. Grass alone rarely holds a steep bank through its first season.

What an erosion control visit looks like

We walk the property with you, ideally while you can tell us where water goes in a storm. We look at the roof lines, the slope of the ground, the gullies and the condition of the soil at the foundation. Then we explain what is causing the loss and which fix we would do first.

Most jobs follow the same order. We deal with the source of the water, repair the damaged ground with compacted fill where needed, add the channel, stone or piping that carries the water away, and finish by seeding or covering the bare soil. If the real problem is the shape of your yard, we may point you to grading and regrading as the better first step. To book a visit, use Request a Drainage Visit or call (717) 696-1707.

Erosion on Lancaster lots

Lancaster sits in the Piedmont region of Pennsylvania, with rolling ground rather than flat plain, and the city averages about 42 inches of precipitation a year. September is the wettest month. That mix of slope and steady rain is hard on bare soil, especially on lots where the ground falls toward the house.

Older neighbourhoods add their own problems. Many homes in the city and the older towns around it were built long before modern drainage expectations, with roof water and paved surfaces sending runoff to the same few places. Winter matters too. Heavy snow melting over frozen ground cannot soak in, so it runs across the surface and takes soil with it. Bare patches left by a winter thaw are often where the next gully starts.

Keeping erosion from coming back

Once the work is done, a few habits protect it. Keep gutters clear so roof water does not overflow onto the same weak spots. Leave the seeded or planted areas alone until they are established, and keep heavy traffic off new slopes. After the first few big storms, walk the yard and look at the channels and outlets. A little stone moved by water is normal. A new rill is a sign to call us before it grows.
