FM Area Diversion February Construction Update
FARGO, ND (February 27, 2026) – ASN Constructors reached an excavation milestone this month. More than 40 million cubic yards of material for the FM Area Diversion’s stormwater diversion channel have now been moved. That’s enough to fill the Fargodome more than 18 times.
This progress and other updates can be viewed at https://youtu.be/5Lxh_UqCZCA.
Aqueducts: ASN Constructors continued placing formwork, rebar and concrete for the remaining portions of the flume and conduit structure on the Sheyenne River Aqueduct. Concrete work also continued on the structure’s wingwalls, which will usher both the Sheyenne River through the structure’s flume and diversion channel flows through the conduits below. At the spillway, construction of additional sections of the structure’s concrete base slab is underway, and crews are forming and placing concrete baffle blocks on top of the already completed portions of the spillway’s base.
Authority Administration Building: ASN Constructors installed sheathing and weather barrier on the exterior of the building that will serve as the permanent home for the Metro Flood Diversion Authority. It’s positioned along the southern embankment to provide a direct line of sight during project operations. Work began inside the building, as well, with metal stud framing and mechanical and electrical rough-in work. Crews also began installing the roof at the maintenance building nearby.
Stormwater Diversion Channel: Excavation is nearly 90% completed on the 30-mile channel. In reaches 9 and 10, which are west of the FM metro area and south of I-94, channel excavation and material placement in the excavated material berms continues, allowing the diversion channel to take shape on both sides of the 38th Street West crossing. In reach 6, crews removed the BNSF Prosper shoofly and are excavating the diversion channel plug below. Once completed, excavation in this area will establish a connection between Reaches 5 and 6 of the stormwater diversion channel.
