Floodplain management Exam with
complete solutions
Area of future-conditions flood hazard - Correct Answers -the land area that would be
inundated by the 1-percent-annual-chance (100 year) flood based on future-conditions
hydrology
First-layer coverage - Correct Answers -the maximum amount of structural and contents
insurance coverage available under the Emergency Program
Flood Hazard Boundary Map - Correct Answers -an official map of a community, issued
by the Federal Insurance Administrator, where the boundaries of the flood, mudslide
(i.e., mudflow) related erosion areas having special having special hazards have been
designated as Zones A, M, and/or E.
Flood-related erosion - Correct Answers -the collapse or subsidence of land along the
shore of a lake or other body of water as a result of undermining caused by waves or
currents of water exceeding anticipated cyclical levels or suddenly caused by an
unusually high water level in a natural body of water, accompanied by a severe storm,
or by an unanticipated force of nature, such as a flash flood or an abnormal tidal surge,
or by some similarly unusual and unforeseeable event which results in flooding.
Area of shallow flooding - Correct Answers -a designated AO, AH, AR/AO, AR/AH, or
VO zone on a community's Flood Insurance Rate Map (FIRM) with a 1 percent or
greater annual chance of flooding to an average depth of 1 to 3 feet where a clearly
defined channel does not exist, where the path of flooding is unpredictable, and where
velocity flow may be evident. such flooding is characterized by ponding or sheet flow.
Area of special flood-related erosion hazard - Correct Answers -the land within a
community which is most likely to be subject to severe flood-related erosion losses. The
area may be designated as Zone E on the Flood Hazard Boundary Map (FHBM). After
the detailed evaluation of the special food-related erosion hazard area in preparation for
publication of the FIRM, Zone E may be further refined.
Breakaway wall - Correct Answers -a wall that is not part of the structural support of the
building and is intended through its design and construction to collapse under specific
lateral loading forces, without causing damage to the elevated portion of the building or
supporting foundation system.
, Chargeable rates - Correct Answers -the rates established by the Federal Insurance
Administrator pursuant to section 1308 of the Act for first layer limits of flood insurance
on existing structures.
Coastal high hazard area - Correct Answers -an area of special flood hazard extending
from offshore to the inland limit of a primary frontal dune along an open coast and any
other area subject to high velocity wave action from storms or seismic sources
Developed Area - Correct Answers -an area of a community that is:
(a) a primarily urbanized, built-up area that is a minimum of 20 contiguous acres, has
basic urban infrastructure, including roads, utilities, communications, and public
facilities, to sustain industrial, residential, and commercial activities, and
(1)within which 75% or more of the parcels, tracts, or lots contain commercial,
industrial, or residential structure or uses
(2)is a single parcel, tract, or lot in which 75% of the area contains existing commercial
or industrial structures or uses
(3)is a subdivision developed at a density of at least 2 residential structures per acre
within which 75% or more of the lots contain existing residential structures at the time
the designation is adopted
(b)Undeveloped parcels, tracts, or lots, the combination of which is less than 20 acres
and contiguous on at least 3 sides to areas meeting the criteria of paragraph (a) at the
time the designation is adopted
(c)a subdivision that is a minimum of 20 contiguous acres that has obtained all
necessary government approvals, provided that the actual "start of construction" of
structures has occurred on at least 10% of the lots or remaining lots of a subdivision or
10% of the maximum building coverage or remaining building coverage allowed for a
single lot subdivision at the time the designation is adopted and construction of
structures is underway. Residential subdivisions must meet the density criteria in
paragraph (a)(3)
Development - Correct Answers -any man-made change to improved or unimproved
real estate, including buildings or other structures, mining, dredging, filling, grading,
paving, excavation, or drilling operations or storage of equipment or materials
Emergency Flood Insurance Program
or
Emergency Program - Correct Answers -the Program as implemented on an emergency
basis in accordance with section 1336 of the Act. It is intended as a program to provide
a first layer amount of insurance on all insurable structures before the effective date of
the initial FIRM
Highest adjacent grade - Correct Answers -the highest natural elevation of the ground
surface prior to construction next to the proposed walls of a structure
