About the Project
WHAT IS THE FM DIVERSION?
The Diversion Project is a 20,000 cubic feet per second, 36-mile long, 1,500 foot-wide diversion channel with 32,500 acres of upstream staging.
- This plan was chosen after years of diligent study, public input and joint cooperation between the city of Fargo; the city of Moorhead; Cass County, North Dakota; Clay County, Minnesota; the Joint Cass Water Resource District; and the Buffalo-Red River Watershed District.
- The FM Diversion would reduce a 100-year flood event from 42.4 feet to 35 feet at the Fargo gage. For reference, the 2009 flood of record peaked at 40.8 feet.
- Though not designed to prevent a 500-year flood event, the FM Diversion would give the area a chance by reducing the river level in Fargo from 46.7 feet to 40 feet during a 500-year event.
- The plan includes 150,000 acre-feet of upstream staging. The staging area would only be used for flood events exceeding a 10-year event, or a 35-foot event in Fargo.
HOW IS IT PAID FOR?
- The total cost of the project is roughly $1.8 billion.
- $800 million (45 percent) is the federal share.
- The remainder, approximately $1 billion (55 percent), is the non-federal share.
- Minnesota is estimated to cover 10 percent of the non-federal share. ($100 million)
- North Dakota is estimated to cover 90 percent of the non-federal share. ($900 million)
- It is being requested that the state and the local split the non-federal, non-Minnesota share 50/50. ($450 million each)
- To date, North Dakota has approved $175 million.
- The citizens of Fargo and Cass County have both passed sales tax increases that have been dedicated to help fund the local share. These are each expected to raise $700 million over the life of the tax.
