Proponents of a new Scituate Town Library said they have raised an additional $30,000 since Town Meeting approved the $12 million library project in early November. “We had been told funds come in faster once you are successful,” said Les Ball, co-chair of the Scituate Library Foundation’s Capital Campaign Committee. “We did see that in December and January.” About $670,000 has been raised so far. Though still far from the $2 million goal, Ball was optimistic. “Given where we are, we think that’s very reachable,” Ball said. Organizers also have high hopes of increasing participation in the 1,000 Homes program, which aims to have 1,000 donors donate $1,000 or more apiece. About $5 million of the total cost will be covered by a Massachusetts Board of Library Commissioners grant; the remainder will be paid by fund-raising and town borrowing.
