Barry was retained by the City of Oakland in 2007 to prepare the City’s new Zoning Maps. His responsibilities also included development of communication and outreach materials for the Zoning Update, as well as peer review and technical guidance to the City’s Strategic Planning Division, which led this effort. This was the first comprehensive overhaul of Oakland’s Zoning Ordinance since the 1960s and public education and outreach was critical.

As manager of the mapping component, Barry was responsible for determining the best-fit zoning designations for approximately 110,000 properties citywide. His work included rezoning more than 25,000 properties into substantially new categories, helping to advance the General Plan vision of a revitalized waterfront and downtown, denser transit-oriented corridors, and stable, diverse neighborhoods. Innovative mapping tools were used to clearly convey what was changing and what would remain the same. Draft maps were posted online, allowing residents to comment with a single click. Barry also produced a series of YouTube videos highlighting the provisions of each zoning district. 

The project received the APA Northern Section Hard-Won Victories Award of Merit in 2011.
