A new replacement library opened on October 31, 2009 at 3600 Norbridge Ave. The new library has been funded by a combination of state bond (13.9 million) and public support for a total cost of $22,276,464. The architect for the project is Noll and Tam, Berkeley, California. The contractor for the new building is W.A. Thomas, Inc., Martinez, California.
