A new study finds that many homeowners face a higher flood risk than they expect. It’s a prospect that raises questions about the accuracy of government flood maps that determine insurance coverage, costs, and building sites.

The Neptune Flood Research Group says that the Federal Emergency Management Agency’s (FEMA) flood maps, long considered the gold standard, might not be accurate after all. Instead, the group asserts that these maps may be significantly off from the number of houses actually at risk. The group is the research arm of Neptune Flood Insurance, a private flood insurance company that sells primary and excess flood insurance.
