Check a specific address before moving

City averages help compare places. A particular home’s school assignment, transit service and flood-map coverage need checks at the address.

  • FEMA Flood Map Service Center — search the address, read the effective map and its date, and check any map changes. An unmapped location does not establish an absence of flood risk.
  • NCES public school district directory — find district contact information, then use the district’s official address locator or enrollment office to confirm school assignment. A city name or district boundary alone does not assign a school.
  • FCC National Broadband Map — check reported service at the exact location, then confirm availability and terms with the provider.
  • Check the official transit operator’s route map and timetable for the address and your actual travel hours; the citywide commuting shares above do not measure service on a particular street.
