CFS Risk Assessment & Mitigation 2

Question 1

Which document provides the primary federal framework for floodplain risk assessment in the United States?

Accepted Answer

FEMA's Multi-Hazard Mitigation Planning guidance (44 CFR Part 201)

Answer

44 CFR Part 201 establishes the requirements for State and local hazard mitigation plans, including flood risk assessment components.

Question 2

A FIRM shows a Zone AE with a Base Flood Elevation of 312 feet. A structure's lowest floor is at 310.5 feet. What is the structure's freeboard deficit?

Accepted Answer

1.5 feet

Answer

The BFE is 312 feet and the lowest floor is 310.5 feet, resulting in a 1.5-foot deficit below the BFE.

Question 3

In risk assessment, 'annualized loss' is best defined as:

Accepted Answer

The expected average loss per year accounting for probability of various flood magnitudes

Answer

Annualized loss integrates losses across all flood frequency events weighted by their probability to express average expected annual cost.

Question 4

Which mitigation measure is considered 'wet floodproofing'?

Accepted Answer

Allowing floodwaters to enter a structure with flood-resistant materials used below BFE

Answer

Wet floodproofing intentionally allows floodwaters to enter a structure, using flood-damage-resistant materials to minimize harm.

Question 5

A community wants to reduce flood risk by restoring a wetland in the floodplain. This approach is best classified as:

Accepted Answer

Nature-based solution (green infrastructure)

Answer

Wetland restoration is a nature-based solution that uses natural functions to attenuate floodflows and reduce downstream risk.
