What to expect from lookups here
- 21 counties have no digital FIRM in the NFHL (listed below). Points there come back
"mapped": false. - 2 of the maps are community-numbered, so parts of the counties they sit in may have no digital map.
- The map that has gone longest without a new panel is Upper Sioux Community (270779), last revised 2003-09-03.
- 42 panels carry a placeholder effective date in FEMA's data; for points on those panels
firm_panel.effective_dateisnull.
