As luck would have it your problems caused you to do this completely bass ackwards. In order...you should get your drainage perfected first. Are you sure you will never have another water damage problem? Or do you need to remove more topsoil to get it right? Second you should install the sprinklers. Then seed.

If you need to remove high spots, now is the time. You're not going to have a great lawn this year. Maybe next fall, but it's too late for this summer. You can seed now but the crabgrass will fill in so fast your head will spin.

One thing you could do is seed more white clover. The clover should grow up tall, spread, and wipe out the crabgrass. Then all you have is clover to kill in August before you do the reseed. There used to be a guy on this very forum who managed a golf course just north of Lake Erie. The course was only used on weekends so he actually seeded clover into his course. Then on Friday he would mow it all down low enough to make it playable. The clover did more to enrich his soil than any fertilizer he could have used. Between that and proper watering (deep and infrequent) he turned that golf course into a money maker with happy players for the first time in years.

The sprinklers have already been installed last fall...thats what led to the drainage problem after they hit the footing pipe and all the water damage happened in that one area. I think that water damage is done and no further corrections need to be made in that area. I will try the white clover and see if that helps with the weed issue. Thanks for the help.
