The Landscape crew is onsite to do some of the hard to reach work in the back yard.  We've decided to go with a wood retaining wall to maximize back yard space and deal with the grade change.  This is an interesting project because the lack of an alley makes the rear work much more difficult.  

Posts are embedded in concrete and ready to finish tomorrow 

And the job is done. We've now maximized the useful space in the back yard.
