I-66 Highway Erosion

Filed under: Video — Sheetflow @ 5:22 am

On this I-66 highway project, the main cause of the slope erosion and rills is clean runoff from the highway. I assume there were curbs along the road edge that at some point were removed. I would restore permanent or temporary curbs to direct clean water to catch basins.

I might leave the slopes uncovered. This would depend on what phase of construction this project is in. If it is in shutdown, I would cover with plastic ( I hate using plastic because it ends up in the landfill), or some type of erosion blanket. I might even consider spraying the slope with polyacrylamide and not covering it.

I do like how the area at the base of the slope is lower than the road to the left so it acts like a sediment pond. Rather than pump to a geotextile bag, I would set up a chitosan-enhanced sand filtration (CESF) treatment system, treat and discharge clean water to the catch basin. Or, if the state environmental agency allows, I would use a gel-floc passive treatment system instead.

Creative Slop Bin

I call it a creative slop bin but really it’s an old loading dock. We had to do a storm system repair and needed a place close to the work to hold the vactor slurry temporarily. The catch basin grate has plastic under it.

A Final Inspection

I am conducting a final inspection of erosion controls at a former staging area. Some of the best management practices shown are: silt fence, straw wattles, and hydroseed.

Watch the River Flow

Had to get out of the house, I was going crazy. So, I drove up to the Staircase campground to watch the river flow.

Dusty Spalls

Dusty Spalls-sounds like the name of a cowboy in an old “B” western film. These quarry spalls came with enough crushed rock dust to create a fugitive dust cloud when dropped into a “skip” box.
