Near the South Platte in Morgan County, check the floodplain map

The South Platte River usually runs low and quiet through Morgan County. But it can rise, and the land along it has flooded before.

In September 2013, heavy rain upstream pushed the South Platte far above its normal level, and floodwater spread across low-lying land in northeastern Colorado, including parts of Morgan County. That history is part of why the official flood maps matter here. The federal flood map shows which parcels fall inside a mapped flood hazard area along the river and its tributaries. If a property is in one, a lender will usually require flood insurance, and building or rebuilding can come with extra rules from the county.

A home being “near the river” is not automatically in the floodplain, and a home set back from the bank can still be in one. The practical way to check is to look at the parcel on the official map, not to guess from the view. Flood maps also get updated over time, so an older assumption may be out of date.

Along the South Platte, the FEMA flood map is where to look up the parcel, and Morgan County is where to ask about local floodplain rules.
