This is what I was going to suggest. Drain stuff is horrifying to deal with (I haven’t personally, but a friend in my townhouse neighborhood somehow had the neighborhood low spot; it was awful), but if the water is away from your house and an expert says it’ll help, rain garden.

Perhaps the punching holes in the bottom of the pool would help, too, but maybe it was a wet place even before the pool.
