What the Norcross claim record shows
For Norcross homes, the local precedents are the events behind the most Gwinnett County claims: Late Summer Storms (206 claims), Tropical Storm Ivan (18 claims) and Hurricane Idalia (10 claims).
About 50% of claims with a recorded zone came from outside the high-risk A and V zones, so a moderate-risk label does not mean a Norcross home stays dry.
A newer Norcross home is not exempt: 87% of claims with a known build date involved homes built in 1975 or later.
