Hazard & Disaster Protection - Natural Hazards (Midwest Conservation Blueprint 2026 Indicator)

Definition This indicator represents the protection of communities vulnerable to impacts of hazards and other community-level stressors, which can include natural disasters (e.g. flooding, wildfire, etc.) or human-caused pollution. It prioritizes areas based on the predicted annual economic loss from riverine and coastal flooding, drought, and wildfires. Pixels can take the following values: 1 – Lower risk of loss, not a natural asset 2 – Lower risk of loss, natural asset 3 – Medium risk of loss, not a natural asset 4 – Medium risk of loss, natural asset 5 – High risk of loss, not a natural asset 6 – High risk of loss, natural asset Selection This indicator was chosen as a targetable, important feature of the MLI goals that will be used to track conditions over time and prioritize areas for conservation. Indicators were defined through elicitation and prioritization exercises with federal and state participants. Criteria for the indicators includes 1) actionable, 2) measurable, 3) relevant to multiple groups across the region, and/or 4) representative of other social and/or environmental values. Input Data & Mapping Steps This indicator originates from the FEMA Coastal Flooding, Drought, Riverine Flooding, and Wildfire data layers. To create this layer, MLI partners, members, and staff completed the following mapping steps: projected all input data to NAD83 (2011) UTM Zone 15N, converted all input polygons to 30m rasters, mosaicked all rasters together to get a sum of expected annual losses from natural disasters, and emphasized natural assets within vulnerable areas for a raster with the following values: 1 – Lower risk of natural hazards, not a natural asset, 2 – Lower risk of natural hazards, natural asset, 3 – Medium risk of natural hazards, not a natural asset, 4 – Medium risk of natural hazards, natural asset, 5 – High risk of natural hazards, not a natural asset, and 6 – High risk of natural hazards, natural asset. Finally, we removed highly altered areas using our Highly Altered Areas Mask. For full mapping details, please refer to the Midwest Conservation Blueprint Development Process.
