Please stay on the steel plates! We are using steel plates for a construction access to this long, narrow site. We exit onto the parking lot of an adjacent company. Sediment trackout is not an option. There is no place to install a tire wash, which I would normally require on a project like this. This requires a lot of oversight to work and one of the things we expect is for trucks to stay on the plates so they don’t pick up any dirt on the tires. This driver didn’t get the message, and the excavator operator could have beeped to stop the driver from backing too far.

Steel Plates Trackout
Trackout happens when you back trucks off of the steel plates onto dirt to unload materials. The plan was for trucks to stay on plates, back to the end and dump. The excavator was to move the materials around the site. There is no tire wash on this project as there isn’t room, so staying on the plates is required and necessary. The trackout is onto the neighbors parking lot, our only site access, and they don’t appreciate dirt ending up in their stormwater swale when the rains come.

Pink Eco Pans
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.

Dirty Rock
If you use dirty rock for the stabilized construction entrance you are going to have sediment trackout.

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.

Tire Wash Fail
The photo is taken right at the paved road access to this project. It makes no sense to me why this tire wash is so far back into the site. The fact that the rock exit is so poorly installed and maintained makes it completely ineffective at preventing sediment trackout. i call this a tire wash fail.

Triangular Silt Dike Construction Entrance
We had two goals: (1) keep dirty site water from draining off site and into the existing storm system; (2) allow access to the project for deliveries. Working together with the contractor, we decided that an asphalt berm alone wouldn’t provide enough protection and if installed thick enough to provide protection, wouldn’t allow for trucks to access the site. We also knew that Triangular Silt Dikes (TSDs) could be driven over but would tend to move if not secured to the existing asphalt. Solution: use both; TSDs to provide adequate protection from site discharges and the asphalt berm to secure the TSD flap to the existing asphalt. This worked well and required little maintenance.

Construction Entrance Fail
Another construction entrance fail. Vehicles drive through the Soaker tire wash, over some rock, then over dirt and sand, defeating the purpose of the tire wash. This exit from the tire wash needs to be rock or asphalt to the street. Disclaimer: I do not promote any products or suppliers.

Sediment Track out-I’ve had Enough
Another day, another random drive by construction erosion inspection. This sediment track out is an ongoing issue and remains unresolved and i’ve had enough. I issued a Non-Conformance Report stating that the construction entrance/exit will remain closed permanently unless a solution is found and implemented.
