After more than two-thirds of Flint voters said yes to funding a Flint Public Library renovation, three local foundations announced more than $16 million in financial support for the upcoming project.  The Charles Stewart Mott Foundation, which made an initial grant of $1.2 million in August, now will grant an additional $13.8 million. The Ruth Mott Foundation will grant $1 million, and the Community Foundation of Greater Flint will grant $50,000.
