A repetitive loss property is defined by NFIP as a property that has received how many flood insurance claim payments over a 10-year period?
Answer: At least 2 payments exceeding $1,000 each
NFIP defines a repetitive loss property as one with two or more flood insurance claim payments of more than $1,000 each within any 10-year rolling period.
What is the primary purpose of a Flood Insurance Rate Map (FIRM) in risk assessment?
Answer: To delineate flood hazard areas and establish BFEs for regulatory use
FIRMs officially delineate SFHAs, flood zone designations, and BFEs that communities use for floodplain management regulation and insurance rating.
When conducting a vulnerability assessment, the term 'exposure' refers to:
Answer: The presence of people, property, or systems in hazard areas
Exposure describes what is located in the hazard zone — the inventory of people, assets, and systems that can be affected by flooding.
A floodway is established to:
Answer: Convey the 1% annual chance flood without raising the BFE more than a regulatory surcharge
The regulatory floodway is the channel and adjacent overbank areas that must be kept free of encroachments so the 1% flood can pass without causing more than the allowable surcharge rise in BFE.
Which mitigation action type directly removes structures from flood hazard areas?
Answer: Acquisition and demolition
Property acquisition and demolition permanently removes structures and converts the land to open space, eliminating future flood damage risk at that location.
What does a 'depth-damage function' represent in flood loss estimation?
Answer: The relationship between flood inundation depth and expected percent damage to a structure or content
Depth-damage functions (curves) correlate flood depth at a structure with the expected percentage of value lost, used in tools like HAZUS to estimate flood losses.
Under the Community Rating System (CRS), communities earn credits primarily by:
Answer: Implementing floodplain management activities that exceed NFIP minimum requirements
CRS credits are awarded for activities beyond NFIP minimum standards, such as higher regulatory standards, public outreach, and mapping improvements, which earn policyholders premium discounts.
