State field guide
This release covers Minneapolis, Luverne, Duluth, Moorhead, and Rochester. Census Vintage 2025 whole-metro estimates establish guide order for every metropolitan area containing Minnesota territory. Luverne represents the Minnesota side of Sioux Falls, SD-MN, while Moorhead represents the Minnesota side of Fargo, ND-MN. St. Cloud ranks sixth and falls outside this five-guide set. Metro counts do not measure city population, project demand, site access, or authority over a work area.

Heavy snowfall complicates access. A military and civilian airport plus a working port make current route and surface checks essential.

A short municipal runway, prairie weather exposure, and city right-of-way controls put logistics and delay planning first.

Class B airspace, dense public right-of-way, and a long winter put flight coordination and ground control on the same critical path.

A cross-state airport, flood-sensitive access, and city freight controls put jurisdiction and ground routing ahead of assumptions.

Towered airport traffic and dense institutional sites make the ground plan as consequential as aircraft reach.
