In reguards to the sump. I have the same problem with a flooding back yard. I will dig the hole alot deeper than 4", but wont the hole just fill up with water than i'll be stuck with the same problem. I dont understand.

The holes should be 4 feet deep, not 4 inches. The hole dramatically increases the surface area for the water to perk out of. The weight of the water also helps with the perking - as the hole fills, the water is heavier and pushes the water down into the ground faster. It is possible for the hole(s) to fill, but regardless, they will drain much faster than the surface would have otherwise. If your problem is quite severe, do a second or third hole.
