Unit 5: The NFIP Floodplain Management
Requirements questions with accurate answers
44 CFR 60.1(d) spells out information regarding more strictive NFIP
requirements. What does it state? Ans✓✓✓ Any floodplain
management regulations adopted by a State or a community which are
more restrictive than the criteria set forth in this part are encouraged and
shall take precedence.
According to 44 CFR 59.1, what is a recreational vehicle? Ans✓✓✓ A
vehicle which is:
- Built on a single chassis
- 400 sq ft or less when measured at the largest horizontal projection.
- Designed to be self-propelled or permanently towable by a light duty
truck
- Designed primarily not for use as a permanent dwelling but as
temporary living quarters for recreational, camping, travel, or seasonal
use.
According to 44 CFR 59.1, what is the definition of "manufactured
home"? Ans✓✓✓ A structure, transportable in one or more sections,
which is built on a permanent chassis and is designed for use with or
without a permanent foundation when attached to the required utilities.
The term "manufactured home" does not include "recreational vehicle."
According to 44 CFR 65.2(c), what does "Reasonably safe from
flooding" mean? Ans✓✓✓ That base flood waters will not inundate the
land or damage structures to be removed from the SFHA and that any
,subsurface waters related to the base flood will not damage existing or
proposed buildings.
Are encroachment reviews required for development projects in the
floodway fringe? Ans✓✓✓ No, because projects in the flood fringe by
definition do not increase flood heights above the allowable level.
Are human intervention floodproofing techniques allowed? Ans✓✓✓
Yes, but are discouraged.
Are the standards the same in both coastal AE and riverine AE zones?
Ans✓✓✓ Yes, both have the same minimum requirements.
Besides being properly designed, what should be done to the fill?
Ans✓✓✓ Should also be properly sloped and protected from erosion
and scour during flooding. It is also recommended that the fill extend 10
-15 feet beyond the walls of the building before it drops below the BFE.
Do most standard regulations apply to manufactured homes? Ans✓✓✓
Yes, because these structures are usually used as residential structures.
How are all buildings in V Zones elevated? Ans✓✓✓ They must be
elevated on pilings, posts, piers, or columns.
How can a community apply for an exception to allow floodproofed
residential basements? Ans✓✓✓ It must demonstrate that flood depths
, are less than 5 feet, velocities are less than five feet per second, there is
adequate warning time for the site, and it has appropriate construction
requirements.
How does one prevent solid walls from collapsing due to hydrostatic
pressure? Ans✓✓✓ An enclosure must have opening to allow
floodwaters to enter and leave, thus automatically equalizing hydrostatic
flood forces on both sides of the walls.
How high does a floodproof building need to be according to the NFIP
requirements? Ans✓✓✓ Only to the BFE. However, to receive the
same favorable insurance rates as a building elevated to the BFE using
other methods, the floodproof building will need to be floodproofed to
one foot above the BFE.
How high does NFIP regulations require the lowest level of a building
be elevated? Ans✓✓✓ Above the BFE.
If an enclosed area is used to elevate the building, what regulations must
be followed? Ans✓✓✓ The enclosed area must meet all requirements
that apply to enclosures including the openings requirement.
If Fill is the method of choice, what should the community make sure?
Ans✓✓✓ That the fill should be properly designed, installed in layers,
and compacted.
