CREEK CULVERT IMPROVEMENTS

A creek culvert is a pipe that conveys a creek under a roadway or embankment. Old, damaged, or undersized creek culverts can cause upstream flooding, downstream erosion, or block the passage of fish. Culvert failure can cause road instability and damage. Older culverts can also have high maintenance costs associated with ongoing repairs and sediment and debris removal. Removing, repairing, and enlarging culverts can reduce flooding, improve roadway stability, reduce maintenance costs, and restore fish passage and habitat. When culverts are repaired or replaced, they must be passable for fish, often resulting in a much larger and wider culvert.
