The city of East Grand Forks built an "Invisible Flood Control Wall" to protect the downtown area. The base of the floodwall will protect against flooding up to the 100-year flood level. If a higher flood is expected, the "Invisible Flood Control Wall" is assembled on the base, which will provide protection to a 60-foot river level.

The "Invisible Flood Control Wall" was developed in Germany, and was recently approved by the Army Corps of Engineers for use in the United States. East Grand Forks is the first U.S. city to install one.
