About the Project
WHAT IS THE FM DIVERSION?
The current plan is a 20,000 cubic feet per second, 35-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 200,000 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.
- During a 100-year flood, the staging area would add five days to the duration of existing flooding.
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 committed $75 million, with another $102 million in the Governor's budget for the 2013 legislative session.
- 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 in excess of $200 million over the life of the tax.
