Downtown arenas, municipal courts, apartment buildings are now dealing with flood damage.
And crews are working to pump all the water from several downtown buildings.
Property restoration crews were in downtown Oklahoma City Monday as businesses continue to clean up after Friday's flooding.
You can see large equipment around the downtown area working to dry up buildings.
Heavy rains pounded downtown Oklahoma City Friday night, flooding city streets and buildings.
Steve Griffin is the property manager where Municipal Employees Credit Union is at Walker at Main.
"It was about maybe knee-high on the outside," Griffin says, "as rapidly as the water was running, I'm sure it went passed the door. I came in with my crew, and we had water everywhere, just had to replace all the carpet."
Across the street at the Montgomery building, flood water knocked out power, and more than 50 tenants were evacuated.
And over at 100 North Walker, where city finance and IT employees work, 9 feet of water flooded the basement, knocking out about half the city government's phone lines.
"We're still assessing the building, but we do think it'll be quite a while before we can get the building up and running because there was extensive damage to our elevator system, and we may have to replace the entire elevator," Kristy Yager, City of OKC Public Information Officer, said.
People who live at The Legacy Apartments spent the weekend cleaning up.
Several other city buildings with basements were also flooded.
And Monday, many of the underground tunnels were still closed.
"The flooding just added insult to injury to a city that was already still recovering from the previous tornado," Yager said.
