§ 6.1.2. New or Altered Channels
Grass channels are the most desirable of the various types of new channels for the following reasons:
A.
The grass can stabilize the body of the channel.
B.
The grass consolidates the soil mass of the bed.
C.
The grass controls the movement of soil particles along the channel bottom.
Concrete lined channels are designed to protect the channel body from the erosive potential of high velocities. In addition to concrete-lined channels, other methods to combat erosive velocities in channels may be available and should be submitted to the Director of the Watershed Protection Department for review.
