Dirt on a steep slope tends to slip or corrode when normal rain runs down and heavy rain causes serious and potentially dangerous landslides. Adding the right ribs keeps the dirt on the slope. Some tilt enhancing options do not look very appealing but other ideas use landscaping techniques that can make your steep slope safe and attractive.
Covers low ground
Grass planting will stabilize the surface of the steep slope if you make the seed stick until it sprouts, but keeping this vegetation trimmed and tidy is impossible on a steep slope. Try planting low-height soil cover plants instead, recommends the US Department of Agriculture (USDA). These plants spread superficial roots that keep the soil on the slope in place, but they keep it short and tidy without mowing. Perennial plants, such as short, spreading varieties of juniper also cover the ground all year round naked.
Support Wall
Building a low wall at the base of the slope, also known as a retaining wall or a wall of feet, prevents the soil that slides down to move too far, says Donald Gray in his book "Biotechnology and Soil Bioengineering Slope Stabilization. " This is especially important if your home or other structure is near the base of the slope where moving soil can damage it. The wall must be able to withstand the high weight and pressure of the wet earth so that a single wall of stacked rock will not be sufficient for a steep and steep incline.
Install Drain
Water naturally runs down a steep slope, even in drier conditions when the rain falls. As the soil absorbs moisture, it becomes heavier, and slips slowly or washes down to a degree. Install carefully planned drainage ditches or even buried pipes water pipes where it will do the least damage to the face of the slope. Add a ditch at the top of the slope and connect it to the drains running downhill. This will divert water that would otherwise run straight along the ledge.
Terraces
Cutting into flat sections a slope is known as terraces, and this landscaping project makes the slope usable as well as stable. Many farmers in countries with steep, but fertile slopes cut growing fields directly on the slopes. You will need to consult a landscaping engineer before beginning a terracing project, the USDA advises, because an improperly designed terrace is more dangerous than an unsecured slope, no matter how steep it is. Terraces need support along the edges of each step to prevent collapse and large-scale sliding soil. Source:
