The Watsonville Civic Plaza building is located in one-square block, downtown at 275 Main Street, Watsonville, California. This government building is a 131,000-square-foot multi-use project, plus parking structure. The facility provides space for the City of Watsonville city hall and administrative offices, City Library, County of Santa Cruz Superior Court, and lease space including retail tenants. The downtown location provides a functional setting for the project that also serves as a revitalization engine for its immediate urban environment.

The project was constructed under numerous separate contracts, reflecting economic as well as political requirements. The parking structure was completed first prior to the construction of the main shell and core of the building. The County Courts were located on the first and third floor, City offices (fourth floor), the Library facilities (first and second floor), and for multiple tenants, including a self-help program area, offices for the District Attorney and commercial retail users on the first and third floor.

The Watsonville City Library more than doubled it size of the old library when it moved into its new facilities in April of 2008. As part of the Civic Plaza building, the library located on the first and second floor: first floor housed the children's department, circulation, technical services and the Literacy center. The second floor housed the adult collection, reference, computer Lab, California Agricultural workers' History Center, Teen zone, meeting rooms, study rooms and the administration offices.

New technology was implemented throughout the new library of great benefit to the public. The Children's area features a "Toddle tech" area with eight bilingual Early Literacy stations that are programmed with educational programs targeted towards children from pre-school age to second grade. Patrons of the library can use the new Xpress Check stations to check out their own materials-including DVDs, videos and CDs.
