The county's own community in the status book, unincorporated Green County (community 550157), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Green County in radon zone 1, a predicted average indoor radon screening level greater than 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
