FIS 2.4 – Flood Protection Measures: Channelization Projects

Channelization Projects are man-made channels or waterways that are designed to increase the flood carrying capacity of a stream and, thereby, reduce flood elevations.

For a channelization project, the information in this section includes the:

  • Type of channel (e.g., grass, concrete, gabion lined, etc.)
  • Name of the agency or organization that constructed the channel
  • Date of construction
  • Name of the agency or organization that maintains the channel

Also, this section describes if the base flood is contained within the channel, and if not, the extent of flooding that will occur outside the channel.
