Floodplain management questions with accurate
answers
30-year setback Ans✓✓✓ a distance equal to 30 times the average
annual long term recession rate at a site, measured from the reference
feature
60-year setback Ans✓✓✓ a distance equal to 60 times the average
annual long term recession rate at a site, measured from the reference
feature
Area of future-conditions flood hazard Ans✓✓✓ the land area that
would be inundated by the 1-percent-annual-chance (100 year) flood
based on future-conditions hydrology
Area of shallow flooding Ans✓✓✓ 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 Ans✓✓✓ 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 Ans✓✓✓ 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 Ans✓✓✓ 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 Ans✓✓✓ 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 Ans✓✓✓ 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
