I took this photo of a construction site across from the Frye Art Museum in Seattle. I liked the colors and all of the stacked pink eco pans.

Plastic Covered Slope
Here is a nice, plastic covered slope. They have placed sand bags on the seams, the seams are overlapped at least 12 inches and the plastic is run all the way to the bottom of the slope. This is a riverbank habitat restoration project on the Duwamish Waterway.

Excellent Tire Wash
This here is an excellent tire wash. Why? Because it is long enough for two tire rotations. In addition, quarry spalls are installed at the entrance and exit of the tire wash. To the left of the tire wash, the contractor placed quarry spalls so vehicles entering the project don’t have to drive through the tire wash.

Leaky Containment
I wondered why, after several days of rain, this containment had so little water in it. It’s because there are small holes in the bottom and it’s a leaky containment. I hope the generator doesn’t spring a leak.

Slope Covered with Plastic
We have covered a slope above the Duwamish Waterway with plastic until landscaping occurs in December. The contractor has done a great job overlapping the plastic sheets and securing them with sand bags.

Sod Berm Perimeter BMP
This is not one of my projects but we have used this method on occasion. Why install silt fence when you can create a sod berm perimeter BMP?
In this case, the area is small and it is surrounded by vegetation so the risk of erosion and turbid runoff is low. In addition, the sod is full roots and seeds so it will regrow in place, providing additional erosion prevention.

Gravel Berm
When we rebuilt this road, we had the contractor blade the gravel base course into a berm along the edge. This created a berm to project the bare area on the left from erosion caused by runoff from the roadway.
The gravel berm was bladed smooth just before installing a curb along the edge of the road. The bare soil was hydroseeded with bonded fiber matrix.
By using the gravel in this way, we avoided installing silt fence, preventing the soil disturbance that causes and keeping a bunch of plastic out of the landfill at the end of the project.

Biodegradable Erosion Control BMPs: Burlap Fence Compost Sock
Biodegradable Erosion Control BMPs: Burlap Fence Compost Sock
My goal was 100% biodegradable BMPs on this habitat restoration project. In this video I show the burlap silt fence and the compost socks.

Steel Plate Construction Access
This is a steel plate construction access that we built across a live stormwater swale. We have installed compost socks along the edge to keep construction runoff out of the swale.

Compost Sock Catch Basin Berm
This compost sock catch basin berm works well as it is heavy enough to stick to the asphalt. Note the tear and I would keep an eye on it during inspections.
