Tips to Prevent Erosion & Unstable Slopes

Water is the most common cause of unstable slopes, mud slides and erosion.

  • • Check your property for signs of earth movement, such as leaning trees, or cracks in the soil and under sidewalks. If you have a problem, contact a soils engineer (see the Yellow Pages, under "Engineers-Geotechnical-Soils") to evaluate the situation.
  • • In general, trees and plants with strong root structures help prevent soil erosion but do not prevent landslides.
