Hydrologically disconnected definition
Hydrologically disconnected means a road segment from which road runoff is not delivered to a watercourse. Hydrologically disconnecting a road segment is accomplished by the following: 1) installing drainage facilities and structures at sufficient intervals to minimize the volume of water being discharged from the road surface at any given point; 2) installing the last drainage facility up grade from the watercourse crossing where water can be discharged off the road without entering the watercourse via overland flow; and 3) diverting water that has been captured by the road onto stable portions of the forest floor that dissipates energy, facilitates percolation, and resists channelization.
