González's book Latino City: Urban Planning, Politics, and the Grassroots provides an in-depth case study of new urbanism, creative class, and transit-oriented models of planning and their implementation in Santa Ana, California, one of the United States’ most Mexican communities. It provides an intimate analysis of revitalization plans re-imagine and alienate a place, and how community-based participation approaches address the needs and aspirations of lower-income Latina/o urban and central areas undergoing revitalization. The book provides a critical introduction to the main theoretical debates and key thinkers related to new urbanism, creative class, and transit-oriented models of urban revitalization. It is the first book to examine contemporary models of choice for revitalization of US cities from the point of view of a Latina/o-majority central city, and thus initiates new lines of analysis and critique of models for Latina/o inner city neighborhood and downtown revitalization in the current period of socio-economic and cultural change.
González has published in the Journal of Planning Education and Research and Environment and Planning A, among other journals. He has co-authored or authored Special and Supplemental Issues in Local Environment: The International Journal of Justice and Sustainability entitled Emerging Issues in Planning: Ethno-Racial Intersections, Preventive Medicine on Active Living, and the Californian Journal of Health Promotion examining health disparities in Latina/o communities.
