Robin McBryde will carry out the same role with the U18 coaching team, while Wayne Jones joins the U20 management as assistant coach alongside Pontypridd's SimonKing.
Surrey have also retained eight players on new two-year contracts - batsmen Walters, Matthew Spriegel, Arun Harinath and Michael Brown, bowlers Stuart Meaker, SimonKing and Tim Linley, and wicketkeeper Gary Wilson.
They have done it with a side Fairclough, who led the Bees up from the Conference in 2005, has re-built after losing 13 players in the summer, including the key trio of Dean Sinclair, Nicky Bailey and SimonKing.
