Issue:

South Branch Grants brook headwaters crossed by a forestry road. Metal culvert (1 m) covered by slabs of asphalt and wooden planks. There is a lot of creozote in the wood and asphalt debris in the brook. Some water runoff from the road.

Action Required:

Replace the wooden planks on the culvert with wood that does not contain creozote. Remove the asphalt slabs and stabilize the banks with clean crushed rock on top of a geotextile.
