Coulees, the Vermilion and Acadiana Rain
Lafayette grew up along the Vermilion River, at elevations of roughly 36 to 49 feet. Rain that falls across the city drains through a web of coulees, including Isaac Verot Coulee, Coulee Mine, Coulee des Poches and Coulee Ile des Cannes, which act as natural channels feeding the river. When a storm stalls overhead, those coulees can rise fast and push water toward nearby yards and streets.
The Vermilion itself is unusual. It is a slow, tidal river, and in very heavy rain it can actually run backward. On August 13, 2016, the river at Surrey Street in Lafayette recorded its largest reverse flow, about 11,300 cubic feet per second, as urban runoff overwhelmed the normal current.
Lafayette averages about 62.8 inches of precipitation a year (1991-2020 normals), with June the wettest month. Lafayette Parish maintains more than 2,500 miles of drainage systems, yet heavy bursts of rain still find low spots.
Lessons From 2016 and Hurricane Laura
The August 2016 floods are best known for Baton Rouge, but torrential rain also hit the Lafayette area. The Vermilion reached flood stage, many local schools closed because of flooding, and Lafayette Parish was included in the federal disaster declaration.
Four years later, Hurricane Laura made landfall far to the west at Cameron, yet the National Weather Service reported that its principal rain-band dropped 5 to 11 inches across Jeff Davis, Lafayette and St. Landry parishes. Inland Acadiana does not face storm surge the way the coast does, but wind-driven rain, roof damage and street flooding are real risks during tropical systems.
That mix is why flood cleanup in Lafayette and storm damage cleanup often go hand in hand after a tropical event. A roof that lost shingles can leak for weeks before the stain shows, and a garage that took on street water may hide wet drywall behind stored boxes. A walk-through with a moisture meter after any major storm can catch problems early.
Your First Moves When Water Appears
- Safety before belongings. Keep out of water that may be touching outlets or appliances, and turn off power only if the breaker can be reached from a dry spot.
- Shut off the supply. For plumbing leaks, close the main valve. A water heater has its own cold-water shutoff on top.
- Know your water. Clean supply-line water is Category 1. Water from a coulee, the street or a backed-up drain is Category 3 and should be handled with protective gear.
- Document it. Photograph rooms, waterlines and damaged items before cleanup starts.
- Report drainage problems. Blocked ditches or drains can be reported to Lafayette's 311 service.
- Call for extraction. Dial (888) 817-5061 and we connect you with a local provider for water extraction and drying.
Reading the Moisture: How Pros Plan a Dry-Out
Water spreads farther than it looks. Under vinyl plank, behind cabinets and inside wall cavities, it can stay hidden for days. That is why a professional dry-out in Lafayette starts with measurement.
Mapping. Pin and pinless moisture meters, plus thermal imaging, show where materials are wet and how wet they are. Those numbers define which areas need drying and which need removal.
Removal. Standing water is extracted. Carpet pad, wet insulation and drywall touched by contaminated water are generally cut out and discarded.
Drying. Dehumidifiers and air movers are placed according to the moisture map, and readings are retaken daily until targets are met. Learn more about structural drying.
Repair. With dry readings documented, water damage repair in Lafayette can begin. Feel free to ask the company about its licensing, insurance and staff training, for example IICRC certification.
Mold in Acadiana's Humidity and the LSLBC License
Acadiana summers are hot and humid, and EPA guidance indicates mold can start on damp materials within 24 to 48 hours. Wet drywall behind furniture or under a sink is a common place for it to start unnoticed.
The Louisiana State Licensing Board for Contractors (LSLBC) issues a Mold Remediation license, which is required for remediation work valued at $7,500 or more and calls for 24 hours of board-approved training. Larger home improvement work needs its own registration at the same threshold, and residential construction over $50,000 needs a residential license. Confirm current requirements and look up any company with the Verify Licensure search on lslbc.gov before mold remediation in Lafayette starts.

Historic Districts, Offices and Rental Property
Lafayette's building stock ranges from the Sterling Grove and Freetown-Port Rico historic districts to the Oil Center and the downtown Central Business District. Older buildings may have plaster walls, wood floors and crawlspaces that call for gentler drying methods, while office buildings often need after-hours work to limit downtime.
Property managers can call (888) 817-5061 for commercial water damage as well as residential. The restoration company you are connected with can coordinate with tenants and document conditions unit by unit.
In multi-unit buildings, water from an upper floor can travel down through ceilings, light fixtures and wall cavities, so check the spaces below a leak as well as the room where it started. Landlords should also remind tenants that their own belongings are typically covered only by a renter's policy, and flood coverage for contents is a separate purchase.
Flood Maps, Insurance and LCG Resources
- Check your flood zone. Lafayette Consolidated Government posts flood maps and handles floodplain permits and Letters of Map Change.
- Community Rating System. Lafayette participates in the CRS program, which can lower flood insurance rates for policyholders.
- Flood is separate coverage. Standard homeowners policies generally exclude flood; NFIP policies usually carry a 30-day waiting period.
- Sandbags and alerts. LCG offers a sandbag site locator and LafayetteNOW emergency alerts.
- Keep records. Photos, invoices and drying logs support your claim.
WaterQ cannot speak for your insurer, but good documentation helps. Neighbors in Youngsville and Broussard can reach local providers through the same free line.

Lafayette Water Damage FAQ
Why does the Vermilion River sometimes flow backward in Lafayette?
The Vermilion is a slow, tidal river. During very heavy rain, runoff from the city can exceed the river's normal flow and reverse it. The largest reverse flow at Surrey Street was recorded on August 13, 2016.
How do I report a clogged drainage ditch in Lafayette?
Use Lafayette's 311 service online at 311lafayette.services or call 311 or (337) 291-8200. Clear drainage helps coulees and ditches carry stormwater away during heavy rain.
Where can I get sandbags in Lafayette Parish?
Lafayette Consolidated Government offers a sandbag site locator at lafayettela.gov/sandbags. Locations can change by event, so check before you go.
Does a mold remediation company need a Louisiana license?
For remediation work valued at $7,500 or more, yes. The LSLBC issues Mold Remediation licenses, and you can search any contractor through Verify Licensure on lslbc.gov.
Is WaterQ the company that comes out?
No. WaterQ is a free, 24/7 referral line. We connect you with an independent, local restoration company that handles the inspection and work.
