A site analysis reveals that a property is located in FEMA Flood Zone AE. This means:
Correct Answer
B) A 100-year flood plain with base elevations set
FEMA Zone AE is an SFHA where base flood elevations have been established. The base flood is the event with 1% annual probability of being equaled or exceeded. This designation does not by itself determine one property’s exact risk or every insurance obligation.
Why This Is the Correct Answer
Option B is correct because Zone AE is an SFHA within the 100-year floodplain, where base flood elevations have been established. The base flood has a 1-percent chance of being equaled or exceeded in any given year. The zone alone does not determine one property's exact risk or every insurance obligation.
Why the Other Options Are Wrong
Option A: Flood insurance is not available for the site
Option A says flood insurance is not available for the site. Being in Zone AE does not make insurance unavailable; SFHA properties are often where flood insurance is required for certain loans.
Option C: A 500-year flood plain with no elevations set
Option C describes a 500-year floodplain with no elevations set. That description fits a moderate-hazard area outside the SFHA, not Zone AE, which is in the 100-year floodplain with base flood elevations established.
Option D: The property carries no flood risk at all
Option D says the property carries no flood risk at all. Zone AE is a Special Flood Hazard Area, so it identifies meaningful flood risk rather than none.
AE means A with Elevations
Zone A is the 100-year floodplain; add the E and base flood Elevations have been set.
How to use: Use this to tell Zone AE from plain Zone A on a flood map question.
Exam Tip
Remember that 100-year means a 1-percent annual chance, not one flood per century. Eliminate any answer claiming zero risk or no insurance availability.
Common Mistakes to Avoid
- -Thinking a 100-year flood can only occur once every hundred years
- -Confusing Zone AE with a 500-year or Zone X area
- -Assuming an SFHA location makes flood insurance unavailable
Concept Deep Dive
Analysis
This question tests knowledge of FEMA Zone AE. Zone AE is a Special Flood Hazard Area tied to the base flood, often called the 100-year flood, where base flood elevations have been determined.
Background Knowledge
The base flood, commonly called the 100-year flood, has a 1-percent annual chance of being equaled or exceeded. Zone A areas are SFHAs without detailed base flood elevations, while Zone AE areas have base flood elevations determined. The 100-year label describes annual probability, not a flood that happens once per century.
Real-World Application
An appraiser finds that a subject home sits in Zone AE on the current FIRM. The appraiser reports the zone and map information and considers whether buyers in that market react to the SFHA location and related insurance costs.
