The opportunity presented itself with this deck to add a Double 2x6 Support Beam.  This Support Beam cut the stress load on the Ledger board by over 50%.  It reduced the ledger board tributary load by 85%.

The new support beam now carries the biggest percentage of the load on the deck.

this blog post is not the place to teach about tributary loads.  A quick duckduckgo search pointed me to the following link:
Tributary Areas for Gravity LoadsLast Revised: 11/04/2014 If the beam is supporting a floor, roof, or wall that has a pressure loading normal to the surface, the total force on the beam equals the area of surface supported (i.e. the tributary area)...   http://www.bgstructuralengineering.com/BGSMA/BGTribArea/BGSMA_TA_02.htm

One of the reasons that decks collapse is the connection point at the wall, As seen in the following photo: Ledger Board is not attached to the brick wall.  

Currently: This area is supported by a cobbled up support post that rests on the Lower Stairway.  This is not to building codes and is a SAFETY Issue.

Exterior Deck Re-Stain Before~After Photos~Tips by Scotty

Today's project is staining this deck to preserve the lumber pic.twitter.com/G0LEZlZSbr — Scotty (@StLHandyMan) September 21, 2015



The deck was a few years overdue: existing finish, in many places was completely worn away by the elements and by use.  
Old Stain was worn completely out and was not protecting the lumber  from the elements or wear and tear of normal activities.

After the first coat of stain had ample time to be absorbed by the Oak Deck Materials, it became apparent that a second coat of stain was going to be needed to fully protect the lumber adding years of future use.

Material List for Saving the Deck - Client six thousand dollars with Exterior Stair Rebuild Photos

While dismantling the stairs to replace the rotten stair stringers and posts, it became clear there was a reason that the stairs had rotted.  It wasn't long after getting to the last stair removal that the answer to my question became readily apparent as I was getting doused by the automatic garden sprinkler.

Water Problem from sprinkler- coupled with the style that the previous builder used to construct the stairs by layering the 2x12s instead of using Stair Stringer Hangers also caused water build ups that led the the wood rotting faster.
