Urban Flooding Risks

The ArcGIS ModelBuilder workflow used to build this page compares floodplain with tax parcel data to identify what urban areas are likely to be impacted by a flooding event.

With two shapefiles, a user may apply this model to any city. Outputs include tables of statistical data and a map. The map shows tax parcels that intersect the regulated floodplain (shown in red) and tax parcels within 500 feet of the floodplain (shown in orange).

The examples above were rendered in ArcMap (click for an expanded view). The example below is hosted by ArcGIS Online to provide interactive Webmapping tools.
