Our general landscaping plan is rather informal and uses almost
exclusively perennials as you can see in the after photo of the
back yard. The area north and east of the house is slightly higher
than the house so large amounts of water would pool in the back
yard and the north side of the house in the wet Seattle winters.
We had to install over 600 feet of french drain across the back
yard and around the south side of the shop to divert the water
around the house.
