The City of Martinez retained Barry to serve as its liaison to Contra Costa County during the siting and design of the County’s new administration building. The former County facility, constructed in 1964, had long been a cornerstone of Downtown Martinez, with employees and visitors supporting local businesses and pedestrian activity. However, the building was seismically deficient and functionally obsolete.

As the County evaluated replacement options—including sites outside of Downtown—the City engaged Barry to advocate on its behalf and ensure its interests were fully represented. Barry worked closely with the City Manager, Deputy County Administrator, project architects, and planning staff to inform key decisions related to site selection, historic resources, parking and traffic, and building design and materials. Ultimately, a Downtown site was selected, and the new 71,000-square-foot administration building opened in 2020.
