Erosion Management in Sloped Terrain Landscaping

1. Learning about the things that cause erosion on sloped land

Let's get to the point: what makes erosion happen? Water naturally flows down hills. Because of how strong gravity is, water loves to race down these hills. Heavy rain or bad drainage can make the ground unstable, which can make it slide down the hill. You know what? You could lose a lot of soil every year if you don't do anything. Water runoff and wind are the main causes, but things people do, like building or cutting down trees, also have a big effect. You're halfway there if you know the base. You can learn about the causes and effects of soil erosion at Texas A&M University here.

Plants are more than just nice to look at. They keep you from losing soil on slopes. The roots twist together to make a net that holds soil and slows down water. Have you ever noticed that forests that haven't been touched seem to stay the same no matter what? That's what nature teaches us. Ground covers or native grasses are good options that don't need much care. Hardy plants can handle bad weather and usually do well with little care. Use groundcovers like ornamental grasses or creeping junipers. They are useful as well as pretty. At the Missouri Botanical Garden here, you can find a full guide on how to pick native plants.

Terracing has been around longer than most cities. It's like turning your slope into steps to slow down the water and give plants time to grow. You don't have to grow rice in the Andes to know how useful it is. On a sloped landscape, terracing can be both useful and pretty. You could say that it turns a scary hill into flat areas that are easy to deal with. It's great for things like building a patio or gardening. The change could be very expensive, but it might be worth it. You can get tips on terracing from the USDA's website here.

Boulders and mulch are not just pretty. When you put rocks in the right places, they can stop wind and water from getting through. This helps keep the landscape looking natural. Larger rocks can hold soil in place and slow down water. Mulch, on the other hand, acts like a blanket to protect the soil from erosion and add nutrients back to it. Not only does it look good, but it also keeps weeds from growing, which can help your plants grow. You can find a lot of helpful information about how to design a landscape on the American Society of Landscape Architects' website, like how to use rocks and mulch.

This is the main part of your plan to stop erosion. That's just how it is: water will always flow downhill. But you can safely change the way that flow goes. You might think that a good drainage system costs a lot of money, but simple fixes can work. French drains, swales, and retention basins are all stylish ways to deal with water. Redirecting rainwater to places where it can safely soak in or to a stormwater system can make a big difference. The Environmental Protection Agency (EPA) has a lot of information about how to deal with stormwater here.

Not only landscape architects have to find a balance between beauty and usefulness on sloped land. You won't have to worry about the next heavy rain if you know what you're doing and have the right plants, structure, and water management for your sloped landscape. Accept it and make the most of it.

When you see your sloped land again, remember that it's not a problem; it's a chance. If you make good choices today, tomorrow will be easier. If this helped you or you have more questions, you know I'm here to talk.
