NFIP communities and flood maps

FEMA’s Community Status Book places 9 NFIP communities in Chatham County alone; 7 of them (77.8%) are classed in the Community Rating System (CRS). The best class among the communities counted here is 5 (Chatham County*, Pooler, City of, Savannah, City of and 1 more): FEMA applies that 25% discount to the full-risk premium of Regular Program NFIP policies in those communities, inside or outside the SFHA, not to the whole county; a policy can be excluded if its building does not comply with local floodplain rules. The oldest flood map still in effect in Chatham County dates from 2018-08-16 (Tybee Island, City of).

In Georgia, 5.3% of the Status Book’s communities span several counties or match no county by name, so community counts by county are partial there.
