Geotechnical and erosion control

Design manuals, geohazard risk management assessment reports and other resources for roads and bridges.


The design and construction of roads, and bridges, is a matter of judiciously applying the concepts of soil and rock mechanics. Existing and newly constructed infrastructure is subject to ongoing geohazards. These geohazards might be a rapid landslide, rock fall or a slower process such as wind or water erosion.

This page provides links to design manuals, the department's annual geohazard risk management assessment reports, and other resources related to geotechnical and erosion control.

Geotechnical engineering

Geotechnical Engineering Best Management Practices identifies key geotechnical procedures to be followed on engineering projects:

  • Guidelines for Geotechnical Borehole Abandonment
  • Guideline for Installation of Slope Inclinometer (SI)
  • Guideline for Installation of Pneumatic Piezometers (PP)
  • Guidelines for Installation of Standpipe Well (SW) and Standpipe Piezometer (SP)
  • Guidelines for Rockfall Hazards Protection
  • Guidelines for Rockfall Remediation
