FEMA IS-386 Introduction to Residential Coastal Construction Answers
| Question | Answer |
|---|---|
| When assessing potential flood hazards, the effects of multiple storms should be considered. | True |
| Stillwater elevations in coastal areas will be controlled by the wave crest elevation or the Base Flood Elevation’whichever is higher. | True |
| Which of the following is an example of risk management through hazard mitigation? | Eliminating enclosures below an elevated building. |
| After compiling information about candidate properties, the next task is to: | Conduct a hazard analysis and risk assessment. |
| Designers should minimize the use of breakaway wall enclosures below the BFE in V zones. | True |
| Long-term erosion: | Shifts flood hazard zones landward. |
| Building codes do not apply to existing buildings that are being rehabilitated or modified. | False |
| Risk assessment must account for all of the following EXCEPT: | The building’s ability to remain undamaged over its intended lifetime. |
| Most U.S. coastal States have adopted a model building code and/or specific requirements concerning the construction of buildings in coastal flood and wind hazard areas. | True |
| The footprint of a coastal residence lies 10 feet in the V zone and 40 feet in the A zone. According to minimum NFIP requirements: | The bottom of the lowest horizontal structural member must be at or above BFE, on a solid or open foundation. |
| _ is used to establish BFEs and differentiate flood hazard zones. | Wave height |
| In a coast A zone, which of the following design decisions is likely to result in reduced long-term costs? | Building on an open foundation |
| Designers should ignore the effects of low-frequency, rare events when determining a site’s potential vulnerability to hazards. | False |
| Which of the following is a recommended infill development practice? | Site the building farther landward than the minimum required setback. |
| Which of the following should be avoided in coastal areas subject to wave impact? | Continuous-perimeter wall foundations |
| To determine the probability that a building will be affected by a specific natural hazard event, the designer must know: | Recurrence interval of the event and period of exposure. |
| Areas that are subject to inundation by a flood that has a one percent probability of being equaled or exceeded in any given year are called: | Special Flood Hazard Zones (SFHAs) |
| To be considered a success, a building must: | Resist damage from coastal hazards over a period of decades. |
| Siting downdrift of a stabilized tidal inlet does not protect a building from significant erosion. | True |
| Coastal sediment budget refers to: | The amounts and rates of shoreline accretion vs. shoreline erosion within a defined region. |
| NFIP flood insurance is: | Federally backed insurance obtained through private insurance companies. |
| The NFIP regulations require that buildings be constructed with methods and practices that minimize flood damage. This requirement applies to buildings in: | The SFHA. |
| Because storms are short-lived, the amount of erosion induced by storms tends to be minor. | False |
| If you are standing between the inland side of the primary frontal dune and the beach, what zone are you in? | V zone |
| In a design seismic event, a building that sustains significant damage but protects life and provides safety would be considered a building success. | True |
| Current FIRMs do not account for: | Long-term erosion. |
| Meeting minimum A zone foundation and elevation requirements ensures that a building can resist coastal flood forces. | False |
| Tropical cyclones can cause all of the following EXCEPT: | Tsunamis. |
| Which of the following would cause insurance for a coastal residence to be more costly? | Eliminating openings in the enclosed area below the BFE in an A zone. |
| If you obtain a federally regulated mortgage for your beachfront property and use that property to secure the mortgage, you: | Must obtain flood insurance. |
| A community that adopts __ will be compliant with the regulatory requirements of the NFIP and the NEHRP recommendations. | IBC 2000 and IRC 2000 |
| Which of the following areas are most vulnerable to hurricanes? | Southern Atlantic and Gulf of Mexico coasts |
| FIRMs will give the designer the following information: | Base flood elevation and flood hazard zone. |
| In evaluating existing hazard information, designers should: | Check the date of the FIRM. |
| Failure to provide a continuous load path from roof to foundation may lead to structural failure. | True |
| Which of the following is a raw land development siting practice to be avoided? | Place a road close to the shoreline, with small lots grouped between it and the shoreline. |
| Wind damage to a building depends on: | The shape of the building and the type, size, and protection of openings. |
| Safety factors are inherent in the design process for wind but not for flood. | True |
| Siting strategies for reducing risk include all of the following EXCEPT: | Maximizing the building footprint to better distribute loads on the structure. |
| Prudent siting and insurance are both mitigation approaches. | True |
| If more sediment is transported by coastal processes or human actions into a given area than is transported out, shoreline accretion results. | False |
| Which of the following causes the most severe flood damage to coastal buildings? | Breaking waves |
| It is prudent to incorporate freeboard in the design of a coastal building. | True |
| In a hurricane, even minor damage to the _ can lead to large economic losses. | Building envelope |
| In identifying candidate coastal properties for development, past development practices in the area are one of the best indicators of potential success. | True |
