Flood Risk and Insurance Challenges in Kentucky, West Virginia, and Tennessee

Executive Summary 

Catastrophic flooding during the early months of 2025 has further highlighted the increasing flood risk across Kentucky, Tennessee, and West Virginia, driven by intensifying rainfall, mountainous terrain, and aging infrastructure. Despite this rising hazard, due to price increases under the National Flood Insurance Program’s (NFIP) Risk Rating 2.0, flood insurance participation is declining rapidly from a very low base, leaving the region financially exposed. This report analyzes the protection gap and highlights the opportunity for private market solutions.

Key data points include:

• Recent significant flooding events:
  • 2025 Flooding: 21 deaths, 1,300+ flood insurance claims
  • 2022 Eastern KY flood: 44 deaths, ~9,000 properties damaged
  • 2016 WV flood: 23 deaths, $1.1B+ in property damages
  • 2010 Nashville flood: 21 deaths, $2B+ in property damages
• Flood exposure is significantly underestimated:
  • FEMA maps identify ~365,000 buildings in high-risk flood zones across the three states (as of 2024)
  • First Street Foundation estimates ~950,000 properties face substantial flood risk, 2.5x higher (as of 2020)
• Insurance coverage is critically low and declining:
  • Fewer than 1% of homes have flood insurance across all three states (as of year-end 2024)
  • In the 2022 KY floods, 95% of damaged homes were uninsured
  • From 2021-2024, NFIP policies across the three states fell by 17%
• Over the 20 years ending 2024, insured flood losses exceed $600M, with far greater uninsured losses
• Premium increases under Risk Rating 2.0 are straining affordability:
  • Dozens of counties across the region are facing premium increases of 200% or more
  • Many Appalachian counties face premiums equal to 6–9% of household income

Neptune CEO Trevor Burgess commented, “Across the United States, millions of homes face rising flood risk, yet too many remain uninsured due to affordability challenges and outdated flood maps. Nowhere is this crisis more evident than in central Appalachia, where flood exposure is climbing, insurance participation is falling, and federal solutions are faltering. The private flood insurance market is here to help close the protection gap.”

Flood Risk in Kentucky, Tennessee, and West Virginia 

The central Appalachian states of Kentucky, Tennessee, and West Virginia have emerged as some of the most vulnerable areas in the United States to severe flooding. Driven by a combination of steep terrain, aging infrastructure, and increasingly erratic climate patterns, these states face a mounting threat from both riverine and flash flood events. Over the past two decades, repeated disasters — from the May 2010 Nashville flood to the June 2016 West Virginia flood and the July 2022 Eastern Kentucky flood — have caused widespread devastation, claiming lives, destroying homes, and imposing hundreds of millions of dollars in damages. Most recently, two significant flooding events during February and April of 2025 have resulted in significant damage, with both weather events bringing double digit inches of rainfall across the region, causing many fatalities and thousands of flood insurance claims to be filed with the National Flood Insurance Program (NFIP). The full extent of the damage caused by these events will be realized in the coming months. Despite their inland location, Kentucky, Tennessee, and West Virginia are far more exposed to flooding than many might assume and data sources sharply diverge on the true scale of that risk. According to FEMA’s official maps, there are approximately 120,000 buildings in high risk areas (known as Special Flood Hazard Areas (SFHAs)) in Kentucky, 110,000 in Tennessee, and 135,000 in West Virginia. However, these figures are widely believed to underestimate real-world exposure. First Street Foundation’s 2020 flood model, which incorporates rainfall intensity, terrain, and climate projections, estimates that 234,300 properties in Kentucky, 383,000 in Tennessee, and 331,500 in West Virginia face “substantial risk,” with those numbers expected to rise significantly by 2050. The gap between NFIP-defined hazard zones and independent modeling illustrates the extent to which risk is understated. This misalignment has profound consequences for insurance uptake, regulatory oversight, and community preparedness.

Insurance Coverage Rates

Despite repeated flood disasters and rising exposure, flood insurance coverage in Kentucky, Tennessee, and West Virginia remains critically low. FEMA’s NFIP holds approximately a 90% share of the primary flood insurance market, and their data indicates that across Kentucky, Tennessee, and West Virginia, only about 1% of residential structures are insured against flooding. These figures fall well below the already modest national average of just over 3%, leaving millions of households financially exposed. In Kentucky, for example, as of year-end 2024, just 14,600 of the state’s 1.39 million homes held active NFIP flood policies, while in West Virginia, this number is just 8,000. The coverage gap is particularly glaring during major flood events. Following the July 2022 Eastern Kentucky floods, roughly 95% of damaged homes were uninsured, forcing most families to rely on limited federal disaster grants or personal savings to recover. This persistent underinsurance is not incidental — it reflects a complex set of structural and behavioral factors.

Why Is Flood Insurance Uptake So Low?

• Outdated or Incomplete Flood Maps: Many homes at high-risk of flooding fall outside of FEMA’s designated Special Flood Hazard Areas (SFHAs). Because mandatory flood insurance applies only to properties with federally backed mortgages within these zones, large numbers of high-risk homes are not required to carry coverage. As noted earlier, First Street Foundation estimates more than 230,000 properties in Kentucky face substantial flood risk, compared to just 120,000 in FEMA SFHAs.
• High Rates of Mortgage-Free Ownership: In central Appalachia, many homes are owned outright or financed informally. Without a mortgage from a federally regulated lender, there is no legal requirement to carry flood insurance, even in high-risk areas.
• Affordability Challenges: Premium increases under FEMA’s new Risk Rating 2.0 framework have pushed coverage beyond reach for many. In some counties, premiums will consume up to 7–9% of household disposable income., as discussed in later section of this report.
• Widespread Misconceptions: Many residents believe their homeowners insurance covers flooding, when in fact it does not. This misunderstanding continues to suppress voluntary participation in the flood insurance market.
  • Neptune’s 2024 Annual Consumer Survey found that over 60% of respondents incorrectly believed they were covered for flood under their homeowners policy.
• Limited Awareness and Outreach: Many property owners remain unaware of their exposure, available coverage options, or how to obtain a policy — a persistent gap in public communication.

Geographic Disparities in Coverage

Even in the highest-risk counties, penetration rates remain surprisingly low. Table 1 highlights the counties in each state with the highest NFIP participation rates within SFHAs. Woodford County, KY, has the highest penetration in the state at just under 30%, while top counties in Tennessee rarely exceed 25%. West Virginia, in particular, shows consistently low penetration rates across its highest-participating counties, all below 8%.

	Ohio	307	4,270	7.19%
	Mineral	91	1,269	7.17%
	Hancock	57	829	6.88%

At the other end of the spectrum, Table 2 shows that in many counties, some of which are repeatedly affected by flooding, penetration rates fall below 2%.

	Ritchie	10	688	1.45%
	Wirt	18	996	1.81%
	Monroe	14	734	1.91%

Despite variations between counties, the broader trend is unmistakable: flood insurance uptake across central Appalachia is not only low but is structurally misaligned with real flood exposure. This imbalance has left entire communities vulnerable to repeated financial devastation and underscores the urgent need for improved outreach, updated risk assessment tools, and more accessible coverage options.

Insured Losses

Despite very low flood insurance participation rates across Kentucky, Tennessee, and West Virginia, the NFIP has still paid out more than $600 million in claims across the three states over the past two decades. This underscores the severity and frequency of flood-related losses — even in a region where most properties remain uninsured. Prior to 2017, nearly all flood coverage in these states came through the NFIP. Although the private flood insurance market has seen growth in recent years, it still accounts for a small share of total coverage, and the NFIP remains the dominant source of insured flood loss data in central Appalachia.

Kentucky

Kentucky has repeatedly suffered catastrophic inland flooding. Most recently, the February 2025 floods brought nearly nine inches of rain over four days, causing flash flooding that killed 14 people and triggered 855 NFIP claims, with damages likely in the hundreds of millions. Just two years prior, the July 2022 floods devastated eastern Kentucky, killing 37 people and damaging or destroying over 9,000 homes. That event alone caused thousands of uninsured losses.

NFIP data shows that even with low insurance uptake, the program has paid out over $100 million in Kentucky over the past 20 years (2014-2024). Jefferson County leads the state in claims volume, with more than 2,300 NFIP claims totaling $48.5 million. Other heavily impacted counties include Pike, Floyd, and Oldham, all with significant payouts. (See Table 3)

Table 3. Top 5 counties in Kentucky – NFIP claims (last 20 years)

County	Claim Count	Total Paid Amount ($)
Jefferson	2,341	$48,536,220.62
Floyd	959	$15,156,500.85
Pike	930	$23,055,026.43
Oldham	464	$10,970,364.14
Greenup	316	$7,064,722.63

Tennessee

Tennessee’s most damaging flood event occurred in May 2010, when torrential rainfall pushed the Cumberland River past 51 feet, submerging downtown Nashville and causing $2 billion in overall losses, including damage to major public infrastructure and cultural institutions. The event killed 21 people and resulted in the state’s largest-ever flood insurance payout.

NFIP claims in Tennessee over the last two decades total more than $250 million, with Davidson County (home to Nashville) alone accounting for 3,549 claims and $175 million in paid losses. Other top counties include Williamson, Shelby, and Hamilton, reflecting both urban and suburban exposure to repeated flood events. (See Table 4)

Table 4. Top 5 counties in Tennessee – NFIP claims (last 20 years)

County	Claim Count	Total Paid Amount ($)
Davidson	3,549	$175,076,263.29
Williamson	747	$28,175,509.60
Sumner	632	$13,989,502.09
Shelby	520	$21,403,610.81
Hamilton	520	$11,327,268.16

West Virginia

West Virginia’s steep topography and narrow valleys make it exceptionally vulnerable to flash flooding. In June 2016, a severe rainfall event triggered catastrophic flooding that killed 23 people and caused more than $1.1 billion in damages. Many of the hardest-hit areas had little warning and limited insurance coverage.

NFIP payouts in West Virginia over the past 20 years have exceeded $130 million. Kanawha County leads with 913 claims and nearly $27.5 million in total losses. Other frequently affected counties include Greenbrier, Logan, and Ohio, all of which have experienced repeated flood-related damage. (See Table 5)

Table 5. Top 5 West Virginia – NFIP claims (last 20 years)

County	Claim Count	Total Paid Amount ($)
Kanawha	913	$27,474,765.65
Logan	487	$10,639,513.97
Greenbrier	454	$15,720,725.91
Ohio	384	$6,847,914.35
Mingo	362	$5,721,290.15

Across all three states, insured flood losses through the NFIP now exceed $600 million — and that’s with insurance coverage reaching only a small fraction of buildings. Given the scale and frequency of disasters in the region, uninsured flood losses amount to billions more, with the cost of recovery often falling to individual families, strained local governments, and federal disaster programs. As the private flood insurance market continues to grow, it may eventually provide a broader view of total exposure, but for now, NFIP data remains the clearest window into the financial toll of flooding in central Appalachia.

Trend and the Future

Rising insured losses and long-term fiscal challenges have forced the NFIP to reevaluate its pricing model. In late 2021, FEMA launched Risk Rating 2.0, a major reform designed to transition from legacy flood zone-based pricing to a property-level approach. 

While the reform aims to promote pricing equity and better reflect true flood exposure, its effects have been profound – particularly across central Appalachia. As Risk Rating 2.0 phases in its new pricing approach, average NFIP premiums in West Virginia are projected to rise from $1,133 to $3,074. In rural Kentucky, some households will see increases exceeding 300%. 

Figure 1 visualizes the geographic spread of these hikes, with numerous inland counties across Kentucky, Tennessee, and West Virginia facing steep upward adjustments.

The consequences of these premium adjustments are twofold. First, they reverse years of underpricing in inland and historically subsidized regions. Second, they impose major affordability burdens on low- to moderate-income households. Figure 2 illustrates the affordability pressure, with many Appalachian counties now seeing NFIP premiums consuming more than 6%, and in some cases 7–9%, of household disposable income. These figures far exceed common thresholds for housing-related insurance affordability and have already begun to affect participation rates.

As shown in Figure 3 below, NFIP contracts in force declined steadily across Kentucky, Tennessee, and West Virginia between 2021 and 2024. This drop aligns with the sharp premium increases depicted in Figure 1 and the growing affordability burdens shown in Figure 2, where flood insurance now consumes up to 9% of household income in some counties. These financial pressures help explain the downward trend, as many policyholders appear priced out of coverage.

Still, Risk Rating 2.0 may offer long-term benefits. Clearer, more accurate risk signals will drive proactive mitigation investments, including elevating homes, retrofitting basements, and relocating utilities above base flood elevation. At the same time, rising NFIP costs have allowed for greater participation of private flood insurers in historically underserved markets.

Figure 4 presents the trajectory of average NFIP policy costs from 2022 to 2024 under Risk Rating 2.0. It reflects residential policies located in SFHAs, all with maximum coverage levels. The chart reveals a steady upward trend across Kentucky, Tennessee, and West Virginia, with the steepest increases observed in Tennessee. While these adjustments are phased in gradually — with annual increases capped at 18%  – the eventual shift to full-risk pricing is expected to drive premiums significantly higher. For many households, this transformation signals not just financial strain, but a fundamental shift in the accessibility and structure of flood insurance coverage.

Conclusion

Flood risk in Appalachian states including Kentucky, Tennessee, and West Virginia is accelerating, but flood insurance coverage is not keeping pace. Millions of inland properties face substantial flood exposure, yet fewer than 1% of households are insured. Significant events over the last 2 months highlight the increasing frequency and severity of hazardous flooding in the region, and with federal insurance reform driving premiums higher, the region’s protection gap is widening at a crucial point in time.

Key conclusions from this report:

• The risk is growing:
  • Climate-driven rainfall extremes are increasing both the frequency and severity of inland floods
  • Over 950,000 properties are now considered at substantial risk across the three states
• Insurance participation is collapsing:
  • NFIP policy counts fell nearly 30% in some areas between 2021–2024
  • Premiums now consume up to 9% of household income in high-risk counties
• The current system is unsustainable:
  • The financial burden of flooding is increasingly borne by uninsured homeowners and taxpayer-funded disaster aid
  • FEMA’s Risk Rating 2.0 has improved pricing accuracy but exposed deep affordability challenges
• There is an urgent opportunity for private market solutions:
  • Private flood insurers can offer flexible, actuarially sound products in underserved inland markets
  • With proper support, the private market can help close the protection gap while relieving pressure on public programs

To protect the central Appalachian region from future disaster losses, stakeholders must act now. Expanding access to flood insurance — through modern modeling, improved communication, and competitive private options — is essential. This is not just a matter of resilience, but of equity and fiscal responsibility and a stronger, broader, and more affordable flood insurance ecosystem is both necessary and achievable.
