I am taking down my 3' white picket fence to replace it with an 'iron' fence
of the same height.  (I can weld so I'll make the new steel fence.)

I want pour a continuous curb that will go under the fence.  The fence posts
(steel) will bolt onto the curb.  I think I need to make the curb between 6
to 8 inches wide--haven't figured this out yet.  I reckon 6" would be okay
in the sense that there is no substantial weight bearing downward onto the
concrete.  However, the fence posts will have base plates welded to them and
I might need a wider curb so the bolts do not get too close to the edge (to
prevent cracking the edge of the concrete out where the bolts go in).
Comments on this hoped for and welcomed.

Also, I am not sure how deep to go with the curb.  We live on southern
Vancouver Island with a climate like Seattle.  We don't get much in the way
of frost and it never goes deep.  So, I thought I probably could go down
around 16" below the ground surface and not have to worry about frost
problems.  (I think I'd like the curb to come about 2" above ground.)  I
don't know if this is right thinking or not so I'd be happy to get comments.

Finally, I think I need to also be concerned about going deep enough so the
fence could not be pushed over if somebody leans on it.  Is 16" deep enough
for that?

Thank you in advance,
David Todtman

I don't think the posts will rust.  If they were set into the concrete, then
there is that risk.  I've seen what  you are referring to--the metal just
'melts' away from rust where it enters the concrete.  My posts will not be
set into the concrete but rather they will be fastened to the top of the
concrete by base plates.  The base plates will be welded to the bottom of
the fence post.  The posts will be painted which will protect the surface
from rust.

_Something_ will be going into the concrete: just make sure that it's rust
free and you're good to go: concrete won't keep out water on it's own for
the most part: so steel in it can rust and destroy the concrete work.

As to the curb, the issue isn't the amount of weight yo're going to be
putting on it, but how big and deep it needs to be to keep from moving
about.  This is non trivial.  But are you planning on putting these in
yourself?  I have vague recollections of concrete guys with reasonably
automated curb making devices offering ther services for lawn/garden
edging who would both have a good idea what you need and be able to give
it to you fairly cheap.
