East Palo Alto Library Planning Stages

East Palo Alto Library has outgrown the physical space of the current facility which opened in 1975. In order to effectively meet our community’s needs and improve library services, a Needs Assessment Report was completed in 2017 that analyzed the current use of the library through community meetings, workshops, and surveys. The report recommended that the library increase in size from 7,680 sq. ft. to approximately 21,000-27,000 sq. ft. The community also identified new space options in the report such as a makerspace, teen lounge, outdoor areas, and a community garden.

Pacifica Sharp Park and Sanchez

In September 2018, a report proposed a two-branch model that would allow the Sharp Park location to be redesigned into a new, larger full-service library while the Sanchez location will explore an “open access” service model. A survey was given to the community to gather feedback on both conceptual models. This past February, a conceptual design concept known as The Town Commons was selected by the Pacifica City Council, opens a new window as the preferred concept for moving forward with the Sharp Park redesign. An “open access” service model will continue to be explored for the Sanchez location to allow for accommodation of community spaces in collaboration with Pacifica Parks, Beaches, and Recreation, opens a new window.

Our next steps will involve refining funding strategies and developing design concepts for both locations.
