One option to rabbiting for the lattice, is to use a vinyl product that is a
track that the vinyl lattice fits into to..I used this to build a privacy
fence on top of a block wall just last month..Although theres a bit more
work involved to attach the track to the 2X4, or 2X6 framing.
Also, re: height, there are cities here in so. calif. that allow you to
erect a 2' high privacy fence on top of an existing 6' wall, so check your
local building code. As for attaching the sill, or bottom plate to the block
wall, some cities require pressure treated lumber that has to be bolted, via
all thread epoxyed into the block wall, once again, check your local
building code, doing it this way will eliminate any possiblity of the fence
coming down, or you could do it the cheap,fast way, by using liquid nails on
the bottom, and shooting it down with a Hiltie.
I don't draw well but here's what I wrote...
"The bottom piece will trap water. Not good even if you use pressure
treated. You could mitigate that by making a rabbet rather than a
dado in the bottom piece, sloping the bottom of the rabbet a bit,
using solid lattice and nailing the bottom of the lattice into the
edge of the rabbet."
Basically, instead of this...

with the bottom of the rabbet sloped out board so it will drain. The
idea of using a grooved piece of plastic for the bottom is good too but
I'd drill weep holes into it.

I've seen those around here. Might be the way to go but I was trying to
avoid adding any braces on the sides. You're probably right about the weak
design though. First big wind might do it in. Still thinking....
