4 What environmental problems do we find on road projects?

5 Improper Dumping

6 No toe wall. Erosion, soil contamination evident.
Landfill No toe wall. Erosion, soil contamination evident.

7 Landslide ready to go

8 Side Casting Damage

9 Road Side Dumps Dumping into ravine
Destruction of the fragile vegetation on slope Discarded waste material mars a scenic landscape

10 Waste material dumped indiscriminately
Road Side Dumps Waste material dumped indiscriminately

11 Road Side Dumps

12 Looks can be deceiving …..
Well completed road with parapet wall But .. behind the wall Excess waste material pushed into ravine

13 Unauthorized Dump Sites

26 Improper Cut Slope Stabilization

27 Cut Slope Erosion

28 Cut Slope Failure

42 Excessive Height and Poor Stability

43 Borrow Areas Not Operated Considering Restoration
