Our two simple Methods for Erosion Control.

Drainage water management - Erosion Control that Works for your Property.

Vegetation - Preparing hillside as vegetation can prevents erosion.

Mudslide Prevention - Which Strong Shrubs Prevent Erosion

Larger shrubs and trees will stabilize hillsides even more, preventing soil erosion and mudslides on your property and helping to keep your neighbors safe, as well.

Here are a few you can find at Green Thumb:

  • Manzanita

  • Toyon
  • Southern California Walnut

What is a landslide?

Landslides are a geological event that occurs when a slope has failed typically due to overexposure or underexposure of water.

Water acts as a cohesive. With too much water, the soil gets heavy and can pull away. With too little water, the glue-like quality begins to give way.

Slopes have soil with varying degrees of clay. When the clay soil has an overexposure to water like heavy rain or a broken water line, the clay will absorb as much water as it can.

Once the soil has absorbed as much water as possible, the clay achieves a mud-like viscosity and assumes a soupy, slimy consistency that doesn’t allow for cohesion to the slope/hillside.

In contrast, underexposure to water dries out clay souls and causes them to become brittle. When the clay is depleted of moisture it is no longer able to adhere to the hillside/slope and begins to slide downward due to gravitational pull.


What is the Difference Between a Landslide and a Mudslide:

Mudslides are a type of landslide characterized by their debris flow of rapid churning channels. Mudslides are a direct result of oversaturation of soil to the point where the friction keeping the soil stuck to the slope dissolves.

Mudslides are incredibly fast and powerful.

Landslides in general are the downward, sliding movement of soil, rock, and debris down a hillside or slope. The vast majority of landslides are incurred by multiple factors acting in tangent, the accumulative power of which destabilizes a slope.
