Combined exposures · Flooding, evacuation & humid heat

Flood exposure and what it compounds with in Louisiana

Flood exposure rarely arrives alone. In some Louisiana ZIP codes it overlaps with a second exposure that changes what flooding means there — how many households have no car to leave in, or how many humid-heat days the area already carries. This page is scoped to Louisiana, because these overlaps are regional patterns.

LouisianaData release 2026Mapped, survey & modeled inputs

Across parts of Louisiana, flood exposure shows up in the same ZIP codes as one of two other measurements. Here is exactly what each of the three measurements is, what kind of instrument produced it, and what reference level it does — and does not — have.

How we measure this →
Flood exposureFEMA flood mapMapped · not modeled

This is how much of a ZIP code's land sits inside the 1% annual-chance floodplain — the area FEMA maps as the Special Flood Hazard Area, often nicknamed the "100-year floodplain." Despite that nickname it does not mean one flood per century: the 1% chance applies every single year, so such floods can strike in back-to-back years. It is read off FEMA's published flood maps rather than modeled, and it describes land, not any particular home.

FEMA National Flood Hazard Layer — the Special Flood Hazard Area (1% annual chance). A federal flood-map designation of land; it is not a health limit, and no ZIP on this page is described as having crossed a safety line.

Households with no vehicleCensus survey estimateACS · ZCTA-native

This is the share of households in a ZIP code with no vehicle available, from the Census Bureau's American Community Survey. It counts households rather than people, it is an estimate drawn from a sample rather than a full census, and it says nothing about why a household has no car. Next to flood exposure it is a logistical fact and nothing more: an evacuation that assumes a car is harder without one.

US Census Bureau, American Community Survey — a survey estimate carrying sampling error. There is no federal reference level for this measure, and none is implied.

Humid-heat daysModeled heat stressOccupational reference — not federal

This is the average number of days a year when the daily-high wet-bulb globe temperature reaches 28 °C — a heat-stress measure that combines temperature, humidity, sun and wind. Humidity matters because it slows the body's main way of cooling itself, sweat evaporating from the skin, so the same air temperature is harder on the body when the air is humid. The count is modeled across a 2011–2020 climatology, not measured at your address.

Cornell wet-bulb globe temperature data. The 28 °C line comes from NIOSH/ACGIH occupational heat-stress guidance written for workplaces — it is not a federal environmental limit, and reaching it is not a regulatory exceedance.

What this is — and isn't. These are separate exposures recorded for the same place. This page does not claim one causes another, does not combine them into a single risk number, does not rank areas by how pronounced an overlap is, and does not connect any of them to a health outcome. It reports where two figures are elevated together, and nothing more.

Coverage & how to read this

Three different kinds of measurement sit behind this page, and they are not interchangeable: flood exposure is read off FEMA's published flood maps, households without a vehicle is a Census survey estimate, and humid-heat days are modeled over a 2011–2020 climatology. None of them is a reading taken at your address. A ZIP reaches a list here by ranking among the highest 10% of US ZIP codes for each of that pair's two measurements; the ranking is national, and the lists themselves are Louisiana only. A ZIP with an unobservable measurement is shown as not measured, never as "not impacted" — and a ZIP that is measured and simply does not carry an overlap is not listed at all, so absence from a list here is never a claim that a place is fine. Only the flood leg carries a federal designation, and that designation describes land, not a line any ZIP on this page has crossed. Read the full combined-exposure methodology →

Each ZIP links to its full ZipVitals page. Louisiana only — the national list is on the explainer page.
