A flood polygon is useful. A property system makes it operational.
NWS Flood Watches were in effect in parts of Kansas and Nebraska on September 15 as heavy rainfall raised flooding concerns across the central Plains and upper Midwest.
NWS pages for Olathe/Kansas City, Omaha and Lincoln showed Flood Watches during September 15. The broader NWS message warned that heavy to excessive rainfall through Friday could bring areas of flooding across parts of the central Plains into the upper Midwest and Four Corners states.
Why parcel context changes the workflow
