Hi,

My house was built on a hill with quite extensive ground at a higher
elevation along with natural running water nearby (streams), could
this
be the reason the soil remains water logged. Any help/suggestions
would
be greatly appreciated.

try to find out where the groundwater table is in your vicinity. If
its near the surface, you can't do much to lower it. Otherwise you
might have a inpermeable layer of clay beneath your plot and it might
be worth the effort to bore a few holes through this.

You could try to drain your plot to the the natural streams nearby, if
possible.

You could try planting trees that use a lot of water, like birch
trees. This helps only in the growing seasons.

Excavate, design a garden pool, plant Iris and water plants and enjoy
:-)
