CLOMR Community Notification

The Metro Flood Diversion (Authority), in accordance with National Flood Insurance Program regulation 65.7(b)(1), hereby gives notice of the intent of the communities of:

  • City of Fargo, ND
  • City of Argusville, ND
  • City of Harwood, ND
  • City of North River, ND
  • City of Reiles Acres, ND
  • City of West Fargo, ND
  • City of Prairie Rose, ND
  • City of Horace, ND
  • City of Frontier, ND
  • City of Briarwood, ND
  • City of Oxbow, ND
  • Barnes Township, Cass County, ND
  • Gardner Township, Cass County, ND
  • Wiser Township, Cass County, ND
  • Berlin Township, Cass County, ND
  • Harwood Township, Cass County, ND
  • Raymond Township, Cass County, ND
  • Reed Township, Cass County, ND
  • Warren Township, Cass County, ND

  • City of Moorhead, MN

  • City of Wolverton, MN
  • Wilkin County, MN Unincorporated Areas
  • City of Comstock, MN

to revise the flood hazard information, generally located between the Red River of the North near Georgetown, Minnesota and the Red River of the North near Wolverton, Minnesota.  The flood hazard revisions are being proposed as part of Conditional Letter of Map Revision (CLOMR) Case No. 19-08-0683R for a proposed flood protection project. The Authority is proposing to construct the Fargo-Moorhead Area Diversion Project (Project), which consists of a 30-mile long diversion channel and a 9-mile long borrow ditch/connecting channel.  The diversion channel would extend from the diversion inlet control structure near Cass County Road 17, just southeast of Horace, ND, downstream to its outlet near Georgetown, MN.  Major project features on the upstream end of the project include a southern embankment that extends from high ground in Minnesota to high ground in North Dakota that connects gated control structures on the Red River of the North, Wild Rice River, and the diversion inlet.  The southern embankment and control structures will impound water in the upstream staging area during project operation and will be designed to meet USACE dam safety standards.

The proposed project will result in increases in the 1% annual chance (base) water-surface elevations for a portion of the following streams:

  • Drain 37
  • Red River of the North
  • Wild Rice River

Once the project has been completed, a Letter of Map Revision (LOMR) request should be submitted that will, in part, revise the following flood hazards along

  • Borrow Ditch
  • Comstock Coulee (modeled as Wolverton Creek)
  • County Ditch No. 20 (Lower Reach) (modeled as Oakport Coulee, Lower)
  • County Ditch No. 20 (Connecting Reach) (modeled as Oakport Coulee, Upper)
  • County Drain 21
  • County Drain 45
  • Drain 10 Breakout
  • Drain 14 (upstream of FM Diversion Channel is modeled as Abandoned Drain 14; Maple River to FM Diversion Channel is modeled as Drain 14 Old)
  • Drain 21C
  • Drain 37
  • Drain 53 Breakout (Upstream of Rose Coulee, Drain 27 is modeled as Drain 53; Downstream of Rose Coulee, Drain 27 is modeled as Rose Coulee)
  • FM Diversion Channel
  • Horace to West Fargo Channel (modeled as Shey-Div)
  • Lower Rush River (modeled as Abandoned Lower Rush River)
  • Maple River
  • Maple River Spillway
  • Oakport Coulee (modeled as Oakport Coulee, Upper)
  • Red River of the North
  • Rose Coulee, Drain 27 (modeled as Drain 27)
  • Rush River (modeled as Abandoned Rush River)
  • Sheyenne River
  • West Fargo Diversion Channel (modeled as Sheyenne River – WF to DR 21)
  • Wild Rice River
