Mitigation Techniques & Technologies Flashcards

Under the NFIP, a structure is substantially damaged when repair costs equal or exceed what percentage of its pre-damage market value?

Answer: 50%

Substantial damage is defined as damage where restoration cost equals or exceeds 50% of market value.

Increased Cost of Compliance (ICC) coverage under a standard NFIP policy pays up to how much toward mitigation?

Answer: $30,000

ICC provides up to $30,000 to help bring substantially damaged insured buildings into compliance.

Which window protection method is generally considered most effective for wind-borne debris in hurricane zones?

Answer: Impact-rated windows or tested storm shutters

Tested impact-rated glazing or shutters resist debris; tape provides no meaningful protection.

Dry floodproofing is generally not recommended for flood depths greater than about:

Answer: 3 feet

Above roughly 3 feet, hydrostatic pressure risks wall failure in typical buildings unless specially engineered.

What is the main purpose of the IBHS FORTIFIED Roof standard?

Answer: Strengthen roof systems against high wind and wind-driven rain

FORTIFIED Roof focuses on stronger decking attachment, sealed roof deck, and edge details for wind/rain.

For FEMA Hazard Mitigation Assistance, a project is generally considered cost-effective when its benefit-cost ratio is:

Answer: 1.0 or greater

A BCR of 1.0 or more indicates benefits equal or exceed costs, meeting cost-effectiveness.

Which mitigation option best addresses a home repeatedly flooded by deep, fast-moving water where elevation is infeasible?

Answer: Acquisition and relocation or demolition

Removing the structure from the hazard area permanently eliminates risk where other measures fail.
