Erosion Information
Total Erosion at Crossing: 9.0399 tons/year
Extent of Erosion: Severe
Erosion is occurring and corrective actions can be installed to address the problem.
Notes: Horrible erosion on both sides dumping LOTS of sediment in. Need to realign channel and move 50-100 feet west and replace culverts and create bigger roadside vegetation buffer. LOCATION: Upstream and Downstream along road/culverts respectively.
