What happened in the May 2019 Arkansas River flood?
Keystone Dam releases rose from 160,000 cubic feet per second on May 21 to 275,000 by May 27, and the water reached south Tulsa and Bixby eight to ten hours later. The river came up to Bixby's high school and damaged several homes, Jenks Public Schools ended the year early, and a leaking levee near West 36th Street and South Elwood was rebuilt overnight.
Broken Arrow declared an emergency during the event and urged voluntary evacuation in the 100-year floodplain, mainly south of 131st Street, while also warning about Haikey and Elm Creek flooding. The total number of homes flooded across the area was not published in the sources behind this page, so no figure is claimed here.
The lesson homeowners took from it had less to do with the river than with the warning time. Upstream releases are public information and they move slowly, which gives households in the low ground along the river hours rather than minutes. The guide to the May 2019 Arkansas River flood goes through that timeline in detail.
Is my Broken Arrow address in a flood zone?
Check the current effective map rather than trusting any website, including this one. FEMA's preliminary 2014 panels for the area label the East and Middle Branches of Haikey Creek and mark Zone AE along parts of Haikey Creek and the Arkansas River in south Broken Arrow, but those panels are drafts.
A preliminary map is a proposal, not a determination, and it can differ from the map that is actually in force for your address. The place to look is FEMA's Map Service Center, which publishes the current effective Flood Insurance Rate Maps and lets you search by address. Nobody at a restoration company should be telling you what zone your house sits in.
Zone status matters for insurance rather than for restoration. A flood job is handled the same way whether the map says AE or nothing at all, because the handling follows the water. The guide to Haikey Creek and Adams Creek flooding sets out which crossings go under and how to read the map series.
Why does so much have to be thrown away after a flood?
Because contamination cannot be dried out of a porous material. Carpet pad, fibreglass insulation, particleboard, paper-faced gypsum and upholstered contents absorb both the water and whatever it carried, and no amount of airflow removes the second part. Hard, non-porous materials are cleaned and kept.
That is why a flood scope usually includes a cut line across the walls above the high-water mark. Opening the wall gives access to clean the framing and the plate, lets wet insulation out, and allows the cavity to dry from both sides. It looks drastic on day one and it is the difference between a building that dries and one that smells for a year.
Contents follow the same test. Hard goods, glass, metal, sealed plastics and most solid timber clean up. Mattresses, soft furniture, pressed-board shelving, stored cardboard and anything with a paper core generally do not. The crew sorts rather than guessing, lists what is going, and photographs it before it leaves.
Can floodwater bring sewage into the house?
It can, directly or indirectly. Heavy rain loads sewer systems, and a surcharged system can discharge through a floor drain, a cleanout or a low fixture while outside water is also arriving. Either way the water in the room is handled as contaminated, with removal replacing drying for porous materials.
The practical consequence is about people rather than materials. Keep children and pets out, do not work in it in bare feet or open shoes, and wash thoroughly afterwards whether or not you touched anything obvious. Food, medicine and cosmetics that were in contact with it are not worth the argument.
If the discharge came from the building's own drainage rather than from outside, the plumbing side has to be cleared before cleanup is worth starting. Sewage backup cleanup covers the handling, and the guide to sewage backup after heavy rain in the Tulsa area explains why the two so often arrive together.
What can a homeowner usefully do before the crew arrives?
Stay out of the water if it has reached anything electrical, photograph everything from the doorway, and move upward rather than outward: lift what you can to a dry floor or a high surface. Do not start pulling carpet or running a household vacuum over outside water.
If the water is still rising, people and documents come first and the building comes second. Where it has already dropped, propping doors open and getting stored cardboard off a wet floor both help. Photographs taken before anything is moved are the record that matters later, and they cost nothing but a minute.
Crews are dispatched around the clock as soon as one is available, and in a widespread event every crew in the metro is working, so no arrival window is promised. Call (833) 490-5225 and keep a note of what you have already done, because it changes what the crew brings through the door.
