The city of Evantown experienced two deadly heat waves last summer that revealed the extent of climate change in the region and the poor condition of the city’s low-income housing stock. The greatest casualties during the heat wave were among the elderly and the children of low-income families living in aging public and rental housing. Now the new mayor, who won election decrying the previous mayor’s stumbling response to the crisis, has called together a group of stakeholders to decide how the city should undertake a program of housing retrofits to reduce vulnerability to extreme heat. Should the retrofits focus on public housing or low-income rental housing? Should the city government bear all the cost, or should private homeowners and landlords contribute? What scale and pace of response is appropriate given the uncertainty of climate change and the high costs involved in achieving resilience?
