best footing for 8x8 pressure treated landscape timbers ?

im not a scaper , just doing my own home . want to come up 3 course , 24" , out 3' from north wall which doesnt get enough sun for grass to thrive . then fill it with 16" dirt topped with 8" stone . question is im thinking of digging down 12" below grade then filling with pea gravel to form a footing under timbers in effort to keep them drier and thusly extending their life , plus making less apt to rise/sink . wondering if thats good or if theres a better way . im in michigan thusly 4 seasons with good amounts of rain / snow / dampness

bury one course of the timbers and nail it into the ground with 24" rebar. There are plenty of articles on the internet on how to build it properly

We spec our walls based on these details: http://www.fairfaxcounty.gov/dpwes/p...ll/details.pdf

agree that pea gravel would be a disaster. Like setting a wall on marbles.

i was planning on making around 36" rebar stakes that i drove down thru drilled holes in timbers down thru the stone then 18" into the earth below to keep timbers from moving

surprised that everyones settin timbers on bare earth thusly allowing moisture to wick right into wood
