What to do when your car floods out or gets stuck in mud

Why this happens on an ordinary Tuesday, not just during a hurricane

Roughly half of New Orleans sits at or below sea level, and the city relies on a drainage system built more than a century ago to keep up. The Sewerage and Water Board of New Orleans (SWBNO) runs 24 drainage pumping stations housing 120 drainage and constant-duty pumps, plus 12 smaller automatic underpass stations that kick on when water starts rising, moving stormwater through roughly 90 miles of open canals and another 90 miles of canals running underground. That system was designed for a smaller, less-paved city than the one it protects today. A hard summer thunderstorm can put standing water in the street faster than the pumps can move it out, on a random Tuesday in July with no named storm anywhere near the Gulf.

The city's chronic flood points

Some spots flood first and worst, every time. The Carrollton Ave underpass at the I-10 overpass is a well-known repeat offender - the city has closed both directions there during heavy storms rather than let drivers push through. Claiborne Ave in Uptown floods regularly too, tied to catch-basin issues and high water backing up in the Palmetto Canal. Low-lying, bowl-shaped neighborhoods built on old backswamp ground - Broadmoor, Mid-City, parts of Gentilly - fill with standing water fastest because that's literally the low point water drains toward.

Never restart a car that stalled in standing water

If your engine died while you were driving through water, do not turn the key again. An engine draws air in through the intake, and if the intake is sitting below the waterline, cranking the starter pulls water into a cylinder instead of air. Water does not compress the way an air-fuel mixture does, so when the piston comes up to compress it, something has to give - usually a bent connecting rod or a cracked engine block. That single extra crank is often the difference between a car that needs a tow and a car that needs a new engine.

Salvage assessment or a normal tow? What decides it

How high the water got is what matters, not how deep it looked from the driver's seat. If water reached the door sills, the floorboards, or higher, treat this as a flood-damage assessment, not a routine breakdown - get the vehicle to a shop or your insurer's preferred facility for inspection before anyone tries to start it, and let them check the engine, transmission fluid, and electrical system before you spend a dollar on repairs. If the water only came up around the tires and the engine never took a breath of it, this is usually a normal stuck-vehicle recovery and tow, nothing more.

Hurricane flooding vs. an ordinary summer downpour

Hurricane Katrina put more than 80% of the city under water in 2005 after 53 separate levee and floodwall breaches. Hurricane Ida knocked out power to roughly a million Louisianans in 2021 and took about 10 days to substantially restore across New Orleans. Those are the storms everyone remembers, but the same standing-water risk shows up on a much smaller scale nearly every summer, June through September, whenever an afternoon storm outruns the pump stations. A car stalled at Carrollton and Claiborne on a Tuesday afternoon in August is dealing with the exact same physics as a car stalled during a named storm - it just doesn't make the news.

Why we flatbed a flood-affected vehicle

A vehicle that sat in standing water, even briefly, may have compromised brakes, a soaked electrical harness, or water in places you can't see from outside. We default to flatbed for any flood recovery rather than wheel-lift, so nothing drags, nothing spins, and nothing gets asked of a drivetrain that might already be damaged.
