Mold Removal in River Ridge, on the Levee Beside the Mississippi
Tell us what you are seeing and we will say whether it is a leak, a cold surface the air conditioning is making, or nothing that needs removing. River Ridge sits 3.49 feet above sea level on the natural levee silt loam, where the USDA records a saturated layer perched 1.5 to 4 feet down from December through April and held under pressure by the river standing higher than the land beside it.

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.

What the river's hydraulic head means for a River Ridge wall
The USDA official series description for Cancienne, the natural levee silt loam of the lower Mississippi and its distributaries, describes a somewhat poorly drained soil with a saturated zone perched above clayey lenses at 1.5 to 4 feet below the surface from December through April, and notes that along the larger leveed waterways the water between those clayey layers in the lower part of the solum may be under pressure because of the hydraulic head maintained by the higher water level in the river.

Damp at floor level between December and April?
On River Ridge levee soils that timing is a real clue, because the perched layer rises in exactly those months. Tell us when it appears and when it goes.
River Ridge is a Census place, so Jefferson Parish holds the file
River Ridge has no municipal government, so Jefferson Parish is the permitting and floodplain authority and the parish Class 3 rating applies. It sits on the natural levee, 3.49 feet above sea level and close to the Mississippi, on Cancienne silt loam, and the USDA description of that soil is worth reading carefully if you have damp at floor level in winter. It records a saturated zone perched above clayey lenses 1.5 to 4 feet below the surface from December through April, and notes that along the larger leveed waterways the water between those clay layers can be under pressure because the river is held higher than the ground. That is a seasonal, pressure-driven wetting rather than a leak, and it behaves differently from one: it arrives on a calendar instead of after an event, and it does not stop when a pipe is replaced. Worth knowing before anyone bills you for chasing plumbing. Only 29.4 percent of occupied homes here are rented, the second lowest share we cover, so most of these decisions are the owner's to make, and 219 of the homes are manufactured units, which sit on a different assembly again. Tell us which kind you have.
