Erosion on Ingraham
Mountain Road
| This is a picture of sever
erosion on Ingraham Mountain Road.
Erosion is a common problem when water is not diverted off the
roadbed, softening the roadbed and making it susceptible to ruts (point out
ruts, lack of full crown). It
can be avoided by regular grading to maintain a crown, a high place in the
center of the road, so runoff flows to either side. U-shaped ditches on the sides of the road can contain and
direct runoff to settle into vegetated areas and not the lake! |
