INTEGRATED SOCIAL AND HYDROLOGIC MODELS FOR ENHANCED RESILIENCY OF COASTAL COMMUNITIES UNDER EXTREME WEATHER EVENTS: A MULTI-METHODS STUDY

Communities vary greatly in their capacity to prepare for increased frequency of flooding associated with climate change in urban streams. A multi-methods study was conducted in Duluth, Minnesota and surrounding communities to assess preparedness and evaluate scenarios representing different levels of flood risk. Hydrologic stormwater modeling identified impacts of current and projected future storms and adaptive strategies including current conditions, addition of green roofs to commercial buildings, and rain barrels to residential rooftops. The green roof scenarios led to reductions in peak flows of 11% for the 2” storm to 3% for the 4” storm. Rain barrels were less effective, with a 4% reduction in peak flows with a 2” storm and no effect with the larger storm. Focus groups and interviews with community leaders examined perspectives on climate change, as well as drivers of and constraints to preparedness. Though the communities appear to have high levels of awareness of climate impacts among leaders and a strong water ethic among members, key community decision makers diverge in perceptions of need and perceived capacity to adapt to climate change and extreme weather.
