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.

Perimeter Controls Presentation

I am giving a presentation on Perimeter Controls: Non-standard Practices for Managing Water and Sediment today at noon. Go to Erosion and Sediment Control Association- British Columbia for information and to sign up. It’s only 10 bucks.

Description-Silt fence is not the only perimeter control BMP option. It is not the best option in many situations. In this presentation, I will discuss when silt fence makes sense, when it doesn’t, what other options are available.

For this stockpile cover and berm application, I think the contractor could have used a few more sand bags.

Construction Access with Steel Plates

We built a construction access with steel plates across this stormwater swale. Then we laid compost socks and straw wattles along side of the eco blocks placed along the edges.

The adjacent parking lot drains into the swale and must be protected from dirty construction stormwater discharges.

Another ten year old straw wattle and the plastic is partly degraded but mostly too strong to pull apart.

This used to be a straw wattle 10 years ago. Now it is just plastic mesh BMP graveyard.

Old Excelsior Wattle

I don’t know how old this excelsior wattle is but old enough to grow moss. The straw is well degraded but the plastic mesh is still too strong to pull apart.

This straw wattle on a slope stops rills before they can completely form.
