The Hot Weather and Health Survey project allowed Washtenaw County Public Health (WCPH) to seek broad community input, provide targeted outreach and pilot elements of a healt impact assessment process. From May through August of 2011, the Hot Weather and Health Survey was offered online via Zoomerang and in paper form at a variety of community locations. WCPH worked with partner organizations serving low-income or potentially vulnerable residents to collect written surveys on site at the paricipating organizations. Results were expected to provide critical information about risk perception, emergency readiness, potential response actions and understanding of alert systems among residents specifically related to heat emergencies with a focus on heat-related health impacts more likely to have a disproportionate impact on low-income, vulnerable, and medically fragile residents. This report summarizes the results of the survey and provides recommendations for actions.A good example of the qualitative aspects of a health impact assessment on heat on vulnerable populations.
