High-Risk Culvert Crossing

High-Risk Culvert Crossing

A culvert is meant to be a temporary structure used to move a creek or watercourse underneath a road. All too often a culvert is left in place for too long and the creek becomes severed at the crossing location as sediment accumulates at the intake and the output becomes perched or hanging from erosion.
Culverts are historically undersized as well which causes the flow of the stream through the pipe to accelerate making fish passage more difficult due to velocity and a lack of resting or cover habitat.
