The Town Councillors joined Kerry's family and friends as they planted a wild cherry tree on KGV field near to Maghull Town Hall.
Kerry was just 23 when she was tragically killed as she travelled back on the A3 in Surrey from Bestival in the Isle of Wight.
Some of the friends who gathered to plant the tree were also on the coach.
Two other people, Michael Molloy from Woolton and driver Colin Daulby from Warrington were also killed.
Mayor Cllr Kermode praised Kerry's friends.
Cllr Kermode said: "It was Kerry's friends who came up with the idea to plant the tree in her memory - it was a very poignant tribute.
"While it is heartbreaking to think that a young girl with lots to look forward to should lose her life in such a tragic way, her friends and her family are determined to celebrate the time they had with Kerry.
"They told me she was always the life and soul of the party. They want to remember her that way and celebrate that.
"I have young daughters around the same age as Kerry. I couldn't imagine what her family must be going through.
"But it must be comforting to know that she brought joy to so many people's lives and she still brings joy to the lives of her friends."
