Rehab greatly reduces the chance of failure especially in steep and ‘high risk’ locations. Landing failure can have a major environmental impact. If it was the result of poor practice it could lead to prosecution. Rehab increases the area available to re-plant. Landings are sometimes burnt as part of the rehab (burning is not covered here).
- A large berm directs water to solid ground.
- Slash has been pulled well back from the landing edge and onto hard ground.
- No rehab has occurred!
- Debris has been pushed into the waterway on two landings.
- Area is known for heavy rain events and culvert crossing (arrow) will fail.
Fixing the problem
- Not enough slash was removed. Slash was only pulled up on the other side of the skid.
- The landing is in risk of failure as major tension cracks are in the fill and minor slipping has happened.
- Slash is now beyond an excavator’s reach because no slash bench was built to contain the slash.
- A bench was made to:
- Reduce risk of fill failure from tension cracks.
- Remove the risk of landing fill collapse.
- Enable the excavator to reach all the debris.
- Debris was put in a safe location. Options include piling up or evenly spreading.
