    "Pluvial flooding is flooding caused by rain that falls faster than the ground and drainage systems can absorb or carry it away. Water can accumulate and damage homes even when they are nowhere near a river or coast. It is often referred to as "urban flooding" but it can cause problems in rural areas as well.
    It is a major source of flood risk, but one that receives less attention than riverine and coastal flooding. A 2025 paper by Ben Nelson-Schmitz and colleagues helps show why that needs to change. They combined National Flood Insurance Program claims with streamflow data to examine flood claims from properties outside mapped 100-year floodplains. Under their classification method, about 87% of the claims they could analyze were attributed to pluvial flooding. They also found that flood insurance coverage outside these mapped floodplains was declining in many states.
    The exact percentage depends in part on the accuracy of the underlying flood maps. Some properties recorded as outside a 100-year floodplain may in fact be exposed to river flooding. The authors acknowledge this limitation and test how their results change under different streamflow thresholds. It is a reason to be careful with the precise estimate, but it does not diminish the central point: rainfall-driven flooding outside mapped floodplains warrants much more attention in flood research and risk management..."
