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.

Building upon the Needs Assessment Report, opens a new window, San Mateo County Libraries — in partnership with the City of East Palo Alto, opens a new window and the County of San Mateo, opens a new window — hired wHY Architecture, opens a new window of Los Angeles to verify the building program, explore the feasibility of building a library adjacent to the EPACenter Arts Center, opens a new window, and prepare design concepts.

On December 12, 2018, a community workshop was held to gather public input, opens a new window on conceptual design options for a possible new East Palo Alto Library. wHY Architecture presented two inspiring design concepts, opens a new window to workshop attendees and gathered feedback. The workshop was live-streamed for community members who were unable to attend in person. See the video below.

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.
