Water Damage Drying in Chalmette When the Enclosure Floods
Drying for the part of a raised house designed to flood, so the water it let in does not stay under the rooms.

Tell us what you can see or smell, roughly where in the house it is, and whether the house is raised or on a slab. Those three things narrow it more than the size of the patch does, because they point at how the water is arriving rather than where it ended up.

Drying the Chalmette enclosure the rules let flood
On a raised Chalmette house, the space under the floor is meant to take water. Federal rules require an enclosure below the lowest floor that is subject to flooding to let floodwater in and out through openings, so the pressure on the foundation equalizes. That protects the structure, and it leaves the enclosure, and whatever is in it, wet when the water goes. Drying there is its own job: pump or extract what is standing, pull out wet insulation and stored belongings, and dry the joists and subfloor before the summer air under the house turns a wet space into a growing one. The EPA window is 24 to 48 hours.
What water damage drying involves in Chalmette
Under a wet Chalmette house: what to decide first
Check the rooms above as well, even if the water never reached them. Wet joists under an air conditioned floor are exactly the combination the building science guidance warns about. Photograph the enclosure, the water line on the piers or walls and everything stored there before it moves. St. Bernard Parish has 23,919 flood insurance claims on record and 231 Chalmette properties have been paid four or more times, so tell the crew if this house is among the repeats: a fourth wetting needs a closer look at the joists than a first.
What was stored below
Boxes, tools and insulation in the enclosure soak up water and hold it against the structure. Move or discard them first.
Whether the joists are wet
Ask for meter readings on the joists and subfloor from below. Dry to the touch is not the same as dry.
Whether the rooms above were reached
If water came through the floor, drying the rooms is a second job, not an afterthought.

Federal regulation 44 CFR 60.3(c)(5) requires that fully enclosed areas below the lowest floor which are subject to flooding be designed to automatically equalize hydrostatic flood forces by allowing the entry and exit of floodwaters, and sets the minimum criteria as a minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding, with the bottom of all openings no higher than one foot above grade.

The EPA states that wet or damp building materials and furnishings should be cleaned and dried within 24 to 48 hours to prevent mold growth, and that if wet or damp materials or areas are dried 24 to 48 hours after a leak or spill happens, in most cases mold will not grow.

Is water still standing under the house?
Tell us how deep and what is stored down there. That sets the first hour of the drying plan.

Chalmette drying questions below the floor
The water only got under the house. Does that need professional drying?
It depends on what is down there and how wet it got. Bare ground and open piers dry with time, but wet insulation, a wetted subfloor and stored belongings hold water against the structure. Ask for the joists to be read with a meter. If they are wet, drying them within 24 to 48 hours is the EPA's line before growth.
Chalmette sits higher than Arabi. Does that help?
Chalmette's interior point is 5.92 feet above sea level, four feet higher than Arabi next door, but a single point says little about a particular lot, and 429 Chalmette properties have flooded more than once. The height does not change the drying clock once water is in.
