The new Costa Mesa branch of the County of Orange Public Library will occupy a site in the heart of Lions Park. The new two-story library will accommodate approximately 22,500 SF including all the components of a complete, fully functioning branch of the county library system.  These include two community meeting rooms, the marketplace, friends-of-the-library bookstore, young adult library, children's library, adult technology stations, study rooms, readers seats and collections. The library is part of a larger project that includes the redevelopment of Lion’s Park for a large outdoor community event space, gardens, concessions kiosk and recreational areas as well as renovation of the old library to become a new community meeting center.

The architecture of the new library models flamboyant mid-20th century modernist architecture (such as John Wayne airport or the JFK TWA terminal) that was in vogue when cities like Costa Mesa came of age in combination with early California architecture (such as the original Spanish settlers’ adobe structures andthe Junipero Serra missions) to create an entirely new architecture that is at once surprising and rooted in its place.
