it sounds like you have an under ground seasonal spring, you are lower than your neighbors, or you have some kind of water leak. check your water meter with all water in the home off. if the dial is moving at all, you have a leak. if not it sounds like you need to instal a french drain.

If your water table is high, it will be next to impossible to fight it. Why not plant a glorious garden that enjoys moist to wet soils? Water gardens are so in vogue now and can be truly beautiful.
