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.
