If you didn't flood you don't have to do anything. If it were underwater for a few days, I'd recommend compost (one of the few times I would).

We had the same here, although a bit less rainfall (2 1/2" instead of 5-6"). No harm done, but things are very, very wet. A good heavy wind may bring down trees at this point!

You could send some my way. We haven't had any for quite some time.

As for you current situation, there is nothing you can or should do. You got a super deep watering. Obviously don't manually irrigate for awhile. Now, this would be an excellent time to test how long your turf can go between waterings. Turn off any automatic irrigation and mark the days to see how long it takes for 30-50% of the grass to wilt. You might be surprised!
