Giant trench will mitigate runoff from bypass project
A massive excavation site adjacent to the Newberg Fred Meyers parking lot is one of the features mitigating the environmental impact of the Newberg-Dundee bypass project.
Its one of seven water quality ponds constructed along the bypass that act as a bioswale on the side of the road; water runoff collects in the swale and slowly seeps back into the ground.
"They help us to filter out the impurities (indirect water pollution) that can flow from the roadway, such as oils, transmission and hydraulic fluids," said Oregon Department of Transportation spokesman Lou Torres.
On the bypass, water will be collected into a pipe thats being installed along the 5.5-mile roadway included in the first phase. It will flow into one of the seven ponds. Besides filtering contaminants out of the water before it infiltrates the water table, the ponds also help control the speed the water flows into the ground in an effort to reduce flooding. The bypass includes a number of environmental measures as required by state and federal law.
