A creek overflow or a flash flood reaches a backyard faster than most homeowners expect. A local television news report described a flash flood in August 2026 that damaged several homes in Franklin when a creek overflowed into backyards. The first hour is for safety, the second for the record and the rest of the day for the drying. This guide sets out the order and what to do at each stage.
Key takeaways
- Stay out of moving water and do not walk the creek bank while the water is high.
- Photograph the water line on the fences and sheds before anything is moved.
- Stop any power to a wet area at the panel if it is dry and safe to reach.
- Silt and mud are removed while they are wet, before the surfaces dry.
- Keep the record of the water path, because the insurer will ask for it.
What should be done in the first hour?
Keep out of moving water, keep children and pets indoors, turn off power to any wet area at the panel if it is safe and call for help.
A creek that is rising can carry debris and move quickly, and the bank can be unstable. Stay away from the water and do not try to cross a flooded yard or drive through water on a road.
If water is inside the house, do not enter a room where the water is touching an outlet or a cord. Turn off the power to that room at the panel if the panel is dry and easy to reach, and call the line.
- Keep away from moving water and the creek bank
- Keep children and pets indoors and out of the water
- Turn off power to the wet room at the panel if it is dry
- Call the line and say where the water is and whether it is rising
How should the water line and the path be recorded?
Photograph the water line on the fences, the sheds, the walls and the garage door before anything is removed, and note the time.
The water line is the mark the flood left on a fence, a shed, a brick wall or a garage door. Photograph it with a scale, such as a coin or a ruler, and note the time and the height. Photograph the path the water took across the yard, the silt it left and any debris.
Keep the photographs with the record of the cleanup. The insurer will ask for the sequence of events, and the water line is the strongest evidence of the depth the flood reached.
How is the mud handled?
Mud and silt are removed while they are wet, because mud that dries into a crust holds moisture and is harder to clean.
Keep children and pets out of the mud, and do not sweep it dry, because a dry sweep puts fine material into the air. Wet vacuum it or wipe it with a damp cloth, and wash the hard surfaces with a detergent.
Porous material that the mud reached, such as carpet pad, drywall to the water line, cardboard and insulation, is generally removed. The removal is recorded and the items are photographed before they leave the house.
What happens to the house during the drying?
The structure is read with moisture meters and dried to a standard for each material, and the drying equipment stays until the readings are met.
The crew reads the floor, the walls, the framing and the slab edge, and marks the wet areas on a plan. The equipment is placed for each room, and the readings are logged at each visit.
Walls and floors are not closed until the readings meet the dry standard. A homeowner who sees a new stain or smell after the equipment is removed should call the line so the area can be read again.
What about the fence, the shed and the yard?
Damage to fences, sheds and yards is often a separate part of the claim, and the record of the water line helps show how the flood affected each one.
Photograph each fence and shed with its water line and any damage, before it is cleaned or repaired. The insurer decides whether the outbuilding is covered under the policy, which often treats detached structures separately.
A yard that has been silted can be raked and reseeded once the ground is dry. The grading should be checked afterward, because a silted low point can send the next storm toward the house.
What should be checked after the water is gone?
The foundation, the garage threshold and the lower walls, and the sump and the drains. A new crack or a damp mark after the water has gone is worth a call.
Look at the foundation for new cracks, the threshold for a gap and the lower walls for a new damp line. A structural professional should look at any crack that is wider or longer than it was before the flood.
Clear the drains and the sump, and test the pump. A flood that reaches a basement often finds the sump at the moment it is needed most.
How flash floods differ from slow creek floods
A flash flood rises quickly and leaves little warning, while a creek flood rises more slowly and lasts longer.
A flash flood follows a short, intense storm, and the water can reach a backyard in minutes. A creek flood builds along the channel over hours and then sits on the low ground while it drains. Both can reach a house, but the warning and the time available to move items are very different.
A homeowner who lives on a low lot near a creek should prepare for both: a list of the items to move to higher shelves, the shut-off locations and the number to call written in one place.
What the record should include in the first week
The first week's record is the basis of the claim, so each day's events are written down.
Write down each day: the water level seen, the work done, the readings taken, the materials removed and the people who were present. A short daily note is easy to keep and very hard to reconstruct later.
Keep the photographs with the notes, and keep a list of any expenses that were paid for emergency work, such as pumping or temporary protection of the house.
Returning to the yard after the water has gone
The yard is checked for hazards before anyone walks it, and the grading is checked before the ground is replanted.
Once the water has gone, walk the yard carefully. Watch for sharp debris, a damaged fence, a sinkhole or a bank that has slumped. Keep children and pets away until the yard is clear.
Check the grading after the silt has dried. A low spot that holds silt can send the next storm toward the house, and filling it with soil is the simplest fix.
Protecting the house while the water is still high
While the water is high, the house is protected by closing the lower openings and moving the most valuable items to higher ground.
Close the lower windows and vents if the water is near them, and place sandbags or a barrier across a garage door if there is time and it is safe. Move valuables and important papers to an upper floor, and disconnect the power to any lower room that could flood.
These steps are taken from the house, not from the water's edge. A homeowner should not go into the yard or near the creek bank to place a barrier.
Working with the crew once the water is down
The crew needs access, a clear record of the water line and the owner's decisions about what can be removed.
Give the crew access to the lower rooms and the outbuildings, and show it the water line and the path the water took. Decide with the crew which items are removed, and keep a list of anything that leaves the house.
Ask the crew to explain the readings at each visit. A homeowner who understands the readings can judge the drying and can decide when the room can be used again.
Why the bank is dangerous after a flood
The bank of a creek is often undercut and unstable after the water has moved, and it can give way under weight.
A creek bank that has been under moving water can be undercut, and the soil can collapse without warning. Stay back from the edge, and keep children and pets well clear. A bank that has slumped toward the house is a hazard to the structure and should be looked at by a professional.
The creek and its banks are the responsibility of the public authorities. A homeowner should report a damaged bank or a collapsed bridge to the appropriate office rather than attempt a repair in the water.
Insurance for the yard, the fence and the outbuildings
The house and the outbuildings may be treated differently under a policy, and the record of each should be kept separately.
Many policies treat detached structures, fences and landscaping separately from the house. The record should list each structure with its water line and its damage, so the insurer can see what was affected.
Flood is generally excluded from standard homeowner policies, so a homeowner should check the policy and any flood endorsement for the yard and the outbuildings. The insurer decides each item on the policy wording.
Returning to normal use
The house and the yard are returned to normal use in stages, after each stage is confirmed by readings or inspection.
The lower rooms are returned to use only after the readings meet the dry standard. The yard is returned to use after the debris is removed and the ground is safe to walk on.
The record of the return to normal use, with the date of each stage, closes the file and gives the homeowner a clear account of what was done.
Frequently asked questions
Can I walk through the flood to check my neighbor's house?
No. Moving water can carry debris and conceal hazards, and the bank can be unstable. Check from a safe place, and call the authorities if someone is in danger.
Who is responsible for the creek?
The public authorities are responsible for the channel and its banks. The homeowner is responsible for the water on the property, and the cleanup covers the water inside the house.
Will my insurance cover the yard?
It depends on the policy. Flood is generally excluded from standard homeowner policies, and the insurer decides on the wording.
How soon should I call?
As soon as the water reaches the house or the lower parts of the yard. The line is answered 24 hours a day.
