Localized Flood Map for Climate Vulnerability Screening

The Localized Flood Map for Climate Vulnerability Screening layer shows potential surface flooding locations in the landscape for the Twin Cities Metro area. These locations, called bluespots, are areas that may be subject to flood during short-term, extreme rain events. The Council's local flood screening tool uses information about the topography of the earth contained in the State of Minnesota's 3-meter digital elevation model (DEM) built from the state's LiDAR effort. Localized flooding locations are determined solely based on depressions in the DEM; no data of existing stormwater infrastructure is considered because this information does not currently exist at a regional scale. This layer should only be used as a screening tool. A low spot shown as a bluespot on this map does not indicate that the area will definitively flood; instead, the area has the potential to flood if a rain event is intense enough and stormwater infrastructure not sufficient. <br/><br/>For more information, visit the Council's Climate Vulnerability Assessment website at: www.metrocouncil.org/cva.<br/>

dsPurpose The Localized Flood Map for Climate Vulnerability Screening layer is part of the Metropolitan Council's Climate Vulnerability Assessment project. The Council initiated a Climate Vulnerability Assessment (CVA) in response to the increased frequency of extreme heat and flooding events associated with climate change. This work supports regional climate mitigation, adaptation, and resilience planning efforts.

The Localized Flood Map for Climate Vulnerability Screening layer is intended for planning, prioritization, and alternatives analysis, not as a definitive source of localized flooding locations. Flooding may or may not occur in identified low points (called bluespots) based on land use, soil type, and stormwater infrastructure. Flooding may occur at locations not identified in the layer due to riverine flooding, local conditions, or changes to the landscape.
