Because they would create a tripping hazard, and you are not
supposed to have a ground like that right in front of the panel where
you would make contact while resetting a breaker.
Simple solution - bury the conduit to the ground rod off to one side
a few feet, and put the clamp below grade in a plastic or concrete
handhole. You can order it with "Ground Rod" on the cover.
And if they ever pave the area, they just raise the handhole up a
bit to sit at finished grade, and then it's always accessible.
NOTE: On new homes they just make a "UFER Ground" bond to the steel
in the footing. Much neater, as it's all hidden in the wall.

Are they going to drive the rod into the ground with bends in it? I
don't see how that is going to work.

That is why you cold-bend them in place. A typical situation is where a
foundation extends beyond a wall (usually a few inches under ground), but you
want the ground rod to emerge from the dirt next to the wall. First you drive
the rod into the ground (usually a foot or two away from the wall) and then bend
it so that it wraps around the top of the foundation and pops up right next to
the wall. Any electrician with more than a few weeks on the job should be able
to do that in his sleep.

The ditch has been dug. They just wanted to make it conform to the concrete
foundation and follow the concrete outside that. It will be placed in there
and buried.

Please log in for more thread options Copper in solution can be super saturated and dip deposited. That is normally
a thin layer at best. Plating is the best way - take a copper
pipe/sheet/wire.... and the sheet you want as the other electrode.
There are reasonable web sites that show electro-plating and offer chemicals
to aid and do the whole job.
Often large crow feet are used with the object suspended above the foot.
