The problem: *A few years ago I overlaid the steps and sidewalk with

So, the concrete steps are 7" below the surface of the stones. *The stones

with only 3" in the step concrete, which would probably have enough holding

power and slightly less "swiss cheese".

What are the other options for securing the posts, if any? *I would be

especially interested the approach others have successfully used in a

similar situation.

It's a good suggestion and one that I considered. Two trees located adjacent to the sidwalk/steps would cause interference with any outboard railing approach.

Can we get a picture of the steps/trees? They must be growing way too
close.
