Army corps of engineers develops Red River valley flood plan

Article Abstract:

The U.S. army corps of engineers is working on a 10-year project to make the flooding that has afflicted the valley of the Red River of the North a thing of the past. The planners decided to keep the river in its course, vacate the floodplain by purchasing all of the low-lying homes, and protect the cities by constructing approximately 28 mi (45 km) of levees and 2.5 mi (4 km) of other floodwalls.
