Frequently Asked Questions (FAQs)
What is the project’s background?
This project replaces and expands the Archibald Library through the conversion of the City-owned Lions East and West buildings. In October 2022, the Library received notice that the Westside Library Expansion Project was successfully funded $6,498,126 through the State of California’s Building Forward Library Infrastructure Grant program. This grant requires a 50% match by the City in the amount of $3,249,063. The total estimated construction cost is approximately $12 million.
Why is the Archibald Library being relocated and expanded?
The current Archibald Library site has been evaluated and found unable to meet the community’s future needs. Continuing to invest in it would not be fiscally responsible. The new facility will better serve residents with flexible, inclusive, and modern amenities.
Will the Archibald Library remain open during construction?
The Archibald Library will remain open during construction to serve the community’s needs. However, some services may be temporarily relocated or adjusted. Residents are encouraged to check the city’s website for the most current information.
