Flood Zones Along the Elk River in Kanawha County, WV

Kanawha County's most severe, most consequential flood risk isn't in Charleston -- it's along the Elk River corridor to the north, where Clendenin and Elkview absorbed the worst of West Virginia's catastrophic June 2016 flood. FEMA has since remapped this stretch of river. Here's what that history and the remap mean for land along the Elk River.

This page covers what's specific to Kanawha County. For the general explanation, see the national guide.

June 23, 2016: a 1,000-year flood on the Elk River

On June 23, 2016, 8 to 10 inches of rain fell across parts of central West Virginia in under 12 hours, and the Elk River responded with a flash flood that NOAA and outside hydrologists characterized as a 1,000-year event for the affected drainages -- statistically, the kind of rainfall intensity expected to occur with roughly a 0.1% chance in any given year. At the Queen Shoals gauge just above Clendenin, in northern Kanawha County, the river rose approximately 28 feet in a matter of hours and crested at 33.7 feet, nearly 15 feet above flood stage, discharging an estimated 83,000 cubic feet per second -- about 30% more volume than the Ohio River's average flow as it passes through Huntington. The statewide flood killed 23 people and is one of the most severe flood disasters in modern West Virginia history.

Clendenin, a town of roughly 1,100 residents on the Elk River in northern Kanawha County, took 7 to 8 feet of floodwater through its downtown and residential areas, destroying the majority of its homes and businesses and forcing many residents to flee to higher ground with little warning. Neighboring Elkview, also on the Elk River, was similarly devastated. Clendenin Elementary School was destroyed outright and later rebuilt with more than $26.8 million in FEMA-approved federal funding -- a scale of loss and rebuilding cost that makes clear this was not a routine, minor flood event for this specific stretch of river.

FEMA remapped this corridor afterward -- your parcel's flood zone may have changed

In direct response to the 2016 flood, FEMA undertook a formal restudy of the Elk River's flood hazard within Kanawha County and the Town of Clendenin, proposing updated Flood Insurance Rate Maps (FIRMs) reflecting the river's actual demonstrated behavior rather than older, pre-2016 modeling. Public comment and appeal periods followed the standard FEMA process, and updated maps for this corridor took effect around mid-2023, per a FEMA press release reviewed for this page. The practical significance for a land buyer: a property along the Elk River corridor in Kanawha County may now sit in a materially different FEMA flood zone -- a different Special Flood Hazard Area boundary, a different Base Flood Elevation -- than it did under the maps in effect before 2016, whether or not the parcel was ever actually inundated during the 2016 event itself.

That distinction matters in concrete, dollar terms. If a specific parcel or structure along the Elk River corridor moved into a newly designated Special Flood Hazard Area under the post-2016 remap, a federally backed mortgage on that property will typically require flood insurance going forward, even if no such requirement existed under the older map -- and any new construction or substantial improvement will need to meet the updated Base Flood Elevation requirement. Conversely, some areas may have moved out of a mapped high-risk zone as the hydrology was refined. Either way, don't assume an older survey, a prior owner's insurance policy, or general familiarity with "the way the river used to flood" reflects the current, in-force FEMA designation -- pull the current flood map for the specific parcel directly.

What to check before buying land along this stretch of the Elk River

Three concrete steps for any parcel in Clendenin, Elkview, or elsewhere along the Elk River corridor in Kanawha County: (1) pull the current FEMA Flood Insurance Rate Map for the specific parcel through FEMA's Map Service Center or the West Virginia Flood Tool (mapwv.gov), rather than relying on a pre-2016 map or general local reputation; (2) if the parcel sits in or near a mapped Special Flood Hazard Area, ask the county floodplain administrator directly about the current Base Flood Elevation and any local floodplain-management ordinance requirements for new construction, additions, or substantial improvements; and (3) if you're evaluating an existing structure, ask specifically whether it was affected by the 2016 flood and, if so, what remediation, elevation, or floodproofing work was done afterward -- a home rebuilt or elevated post-2016 to meet updated standards is a materially different proposition than one that wasn't.

This flood-risk picture is specific to the Elk River corridor running through northern Kanawha County -- it is a different, geographically distinct issue from the county's Charleston-area zoning framework and the 2014 Elk River chemical spill covered in the county hub, even though both involve the same river. A parcel in the Charleston metro core, away from the Elk River's immediate floodplain, faces a materially different flood picture than one in Clendenin or Elkview; don't extrapolate one part of the county's risk profile onto another without checking the specific parcel's own flood-map designation.
