Abstract As the City of Houston's Bureau of Air Quality Control embraced new policies, technologies, and rhetorical strategies, they simultaneously moved through Lukensmeyer and Torres's "four levels of public involvement," which include the information, consultation, engagement, and collaboration levels (Lukensmeyer & Torres, 2006 Lukensmeyer, C. J., & Torres, L. H. (2006). Public deliberation: A manager's guide to citizen engagement. IBM Center for the Business of Government Collaboration Series. Retrieved November 2007 from http://www.businessofgovernment.org/pdfs/LukensmeyerReport.pdf [Google Scholar]). Because of the technical and scientific nature of air quality inspections, increasing public involvement, especially the involvement of those in a predominantly African American and a predominantly Hispanic neighborhood, has been a challenge. This article describes the Bureau's journey through the information level, where the Bureau opens public access and participation in the investigation and reporting process; the consultation level, where Bureau staff go door-to-door in poor and minority neighborhoods collecting citizen feedback regarding perceived environmental hazards; the engagement level, where the Bureau conducts monthly environmental meetings with neighborhood residents; and the collaboration level, where citizens are taught to collect evidence of environmental violations.
