Avoidance/Retreat or Biotechnical Solutions
Although avoidance is not truly a planting procedure, it should be discussed as a viable technique to weigh when it comes to slope restoration using geotechnical engineering design and stability construction. For some sites it will be more economical for homeowners to relocate structures away from slope crests than to mobilize construction crews to perform traditional advanced geotechnical slope stabilization. If structures can be relocated, greenbelts and low-impact slope planting may proceed with less risk to structures.
Biotechnical engineering solutions use both vegetation and inert structural designs to address steep slopes greater than 1.5H:1V, known landslide areas, complicated drainage issues, and slope restoration programs.
