Who knows about stacked-block retaining walls?

Any project worth doing - is worth overdoing when DIY.
especially if you have extra time
and the tools
and the inclination....😉
Well you certainly have the inclination, darn near vertical :)

Thanks for the update. It's been a fun project to watch. I have to admit that it's been a bit overwhelming seeing all that you did, and it got me to rethinking plans for my place.

I've been planning on building a short retaining wall for my drainage ditch that goes through my yard but haven't found any blocks that I really like the look of. Now I'm going to just remove all the dirt and plant grass so I can mow it. More work on the tractor, less money buying materials, and a totally different look.

Sod waterways are the best way to go when possible.

I have a 300 foot sod waterway in my yard that drains the neighboring Farmfield. in 2010 I had to redo it because of all the silt had filled in it, it had become marshy.
I redid where the water runs onto my property so that it doesn’t run quite so fast and now it has held up for 15 years pretty well without silting

Anything you would do differently or could have saved some work looking back?
I would have liked to have a real "compactor". But you can't have every piece of eqpt that you wish for just hanging around. DIY can take months.
Finding a trucker to bring me SAND for fill, that concern reduced somewhat. (Free sand !, a little bit moist. and LOTS of it !)

Wish I had a 3rd pic (of the geotex folded over ontop.)

Tracked vehicle doesn't compact much, but it's moist sand, and its heavy.
I suppose it's weight compacts all the lift layers below.
Those form boards are 4x12 held vertical with #5 rebar stakes into the geotex lift below.

I have laser elevations "before", and will be able to measure settling of the top surface as time passes.

What I most needed, and wasn't able to get, was confirmation that a stacked block wall leaning against a Geotex retaining wall was..... "no worries of soil pressure against the block wall".
(re: Civil Engineer member Sam Wise, see post Who knows about stacked-block retaining walls?) who wrote that the stacked block wall was a decorative facing for the (geotextile) retaining wall.
If that's the case.....
and I tend to believe it🧐
then there's almost no pressure on my stacked blocks.

Anyway, I had to press on, with advice from just one TBN engineer who told me what I wanted to hear and of course it was a sweet sound...

Any more civil engineers willing to opine......?
Is the block wall subject to soil pressure from the geotextile reinforced embankment?

The 5/8clean gravel and the topsoil heap doesn't look like 'much'.
The block mfr approves 42" max (without reinforcement).
