Retaining wall/drainage design for 1930’s Ad0be home in SoCal?

Howdy everybody, posted in masonry as nicely…however in search of some enter on a 1930’s Ad0be house my husband and I are closing on. There’s a failing retaining wall (pure stone, railroad ties, and concrete) that’s desperately needing restore/substitute within the rear of the house together with a patchwork paver, brick, and random concrete, walled-in patio and surrounding walkways that had been put in within the 60’s, 80’s and early 2000’s respectively (there’s dates carved into every part). We have to primarily tackle drainage points to maintain the house free from moisture for apparent causes (mud lol) however we’re scuffling with design. We need to substitute the wall with one thing that may assist spotlight the great thing about the house itself, not distract. We’ve had a number of landscaping corporations out to supply quotes and so they’ve all mentioned to go together with a wall block system and sturdy drainage each behind the wall and channel drains the size of the house. Aesthetically it simply feels off? We perceive the drainage want completely, however is there a cause nobody will quote us for repairing or changing the pure stone wall? Is it just too costly with at this time’s materials prices? Possibly inadvisable because of the slope? Or is it traditionally incorrect? What can be appropriate? And after we requested a couple of stucco end wall, pure stone or a stone veneer we had been merely informed “that is higher”. Any perception or opinions? We need to be good stewards each in design and security for the longevity of the house. Thanks! (Needed to misspell Ad0be/ it thinks I’m asking about this system)
