Need help fixing this swamp we’ve created. We upped the sprinkler time which has been great for the rest of the grass, but waters started pooling in this spot and along the rest of the patio right here. We dug it out to make sure the irrigation line wasn’t broken. So planning on filling it back up and re-sodding, but any advice on how to prevent this from happening again? Was thinking about digging a little more, adding pea gravel and then mixing something(?) with the native soil we dug out. Would that work? Located in Phoenix.
