Is your property in a flood zone?
Flood hazard areas are areas located within the 100-year floodplain, which are defined as any area that has a one (1%) percent chance of flooding in any given year. Smaller scale floods (50-year and 10-year) have a greater chance of occurring in any year and can pose a significant flood hazard to people and property close to the ocean, sound, drainage channels and streams. Floods larger than the 100-year event can also occur. You should become informed as to the flood hazard potential for your property. Click on the map below to determine your base flood elevation.

Types of Flood Zones
Moderate to Low-Risk Areas
- Shaded Zone X: Areas of 500-year flood; areas of 100-year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 100-year flood.
- Zone X: Areas determined to be outside 500-year flood plain.
- Zone A: No base flood elevations determined.
- Zone AE: Base flood elevations determined.
- Zone AH: Flood depths of 1 to 3 feet ( usually areas of ponding); base flood elevations determined.
- Zone AO: Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths determined. For areas of alluvial fan flooding, velocities also determined.
- Zone A99: To be protected from 100-year flood by Federal flood protection system under construction; no base flood elevations determined.
High Risk - Coastal Areas
- Zone V: Coastal flood with velocity hazard (wave action); no base flood elevations determined.
- Zone VE: Coastal flood with velocity hazard (wave action); base flood elevations determined.
Undetermined Risk Areas
- Zone D: Areas in which flood hazards are undetermined but possible.
