Creative Contractor Makes Slope Tracking Excavator Bucket

Leave it to the creative contractor to come up with creative solutions. Confronted with a small, steep slope and wet soil, the contractor didn’t want to risk walking a small caterpiller up and down to roughen it before hydroseeding. Using some angle iron and an excavator bucket, they welded up a slope tracker. The operator tamps the slope with the bucket just like they are compacting the slope. This is the result.

Rough vs Smooth Slope

This is a dramatic example of the effect of rainfall on a Rough vs Smooth slope.

The rough side was “track walked” using a small Caterpiller tractor.   The other side was “back-bladed” smooth with the same tractor.

Both test plots were prepared with the same soil and then sprayed with bonded fiber matrix (BFM) with seed and fertilizer.

Slope Drains

Pipe slope drains are a great best management practice for conveying water down to the base of a slope. Water allowed to flow over a slope will cause rills and gullies to form, depositing tons of sediment at the bottom of the slope. This clip shows a good application of a pipe slope drain, except the pipe doesn’t go to the base of the slope.

Water Flow Over Slope Causes Erosion

Inspecting a project during a rainstorm is sometimes the best way to determine how storm water will flow around the site. It was clear, during this inspection, that the flat area above the slope was graded toward the slope face , which allowed water to flow over and down the slope, causing it to erode. If it was not possible to grade the area above away from the slope, a sand bag berm and a pipe slope drain could have been used to collect the water and convey it to the base of the slope.
