What this page does not tell you
It does not say whether any particular address is protected. A FEMA accreditation status describes this system measured against a design flood event, and USACE states that the database may not represent the totality of levees in the United States. If you need to know what applies to a specific property, your local floodplain administrator holds that answer. How to read an accreditation status.
