Dates are panel effective dates (YYYY-MM-DD). "Placeholder" means FEMA's record carries a non-date such as 9999-09-09. "Over 10 years old" counts panels effective before September 29, 2016. "LOMRs in effect" are Letters of Map Revision not yet folded into a new FIRM. The DFIRM ID appears in responses as flood_zone.dfirm_id and firm_panel.dfirm_id.

Counties with no digital FIRM in the NFHL
