47-year-old mum of two Susan Shaw was killed after being hit by a car during a police pursuit.
Susan was hit by a blue Vauxhall Corsa, which was being chased by police, on High Street in Rishton, near Blackburn, at about 5.50pm on Boxing Day.
Today her family have paid tribute to "one of the kindest people you could ever meet".
A fundraising website has been set up to help with the costs of caring for Ms Shaw's two disabled children, who are both believed to be in their 20s.
A message on the Gofundme page, set up by friend Debbie Hudson, said: "Susan was a well loved member of the community who was sadly killed in a hit and run on the 26 December 2017.
"Funds will go towards funeral cost and caring for her two disabled children."
More than £1,000 had been raised within an hour of the page having been set up.
Plans to plant a tree in Ms Shaw's memory, which would be decorated and lit every Christmas, were announced on the Facebook page for the Switch-On Rishton community group.
Member Nick Hayward wrote: "It is with a very heavy heart that news was given to me last night that one our fundraising superstars Susan Shaw was fatally injured in a hit and run on the High Street in Rishton.
"Susan was an active member of the group - a tremendous help behind the scenes as well as taking part in the fundraising events that have been held over the years."
He said the tree, which would be a tribute to her community work, would be planted at Rishton health centre.
