This silt fence looks pretty ugly and inspection shows it certainly needs maintenance; but does it? The silt fence made sense before we excavated several feet, now it doesn’t. There is a turbidity curtain in the river to the right and the contractor is careful to pull material back from the riverbank. I am going to let this go.

Turbidity Barrier

This is a turbidity barrier, also known as a turbidity curtain. We are using it to contain sediment during a riverbank restoration project.

Temporary Boot Wash

We were excavating a riverbank next to a former Superfund cleanup site and we hit a layer of black soil. I stopped the work and called out an Environmental Agent (EA). The EA took samples of the soil and sent them to a lab for analysis. I had the contractor rope off the area and build a temporary boot wash at the site entrance. It turned out the soil was clean.

Large Woody Debris

Filed under: Video — Tags: , , , , — Sheetflow @ 2:32 am

We have to clear mature trees from this site so we can excavate down to create valuable riverbank habitat. We are saving the trees and will use them as large woody debris like log edges, root wads, and other habitat features.

This was a test to see if we could save the root mass. With a good operator keeping the tree from falling the wrong way, we were able to reuse the tree on the project. So far, we have used about 25 site trees.
