QUESTIONS & ANSWERS(RATED A+)
What is "Basic rule #1" for using maps and data? - ANSWERYou must use the latest
maps and flood data published by FEMA
What is basic rule #2 on what needs a permit in the floodplain? - ANSWERA permit
is required for all development in the SFHA.
What is Basic Rule #3? - ANSWERDevelopment must not increase the flood hazard
on other properties
What does Basic rule #4 say about new buildings in A Zones? - ANSWERNew,
substantially improved or substantially damaged buildings must be protected from
damage by the base flood.
What does Basic rule #5 say about new buildings in V Zones? - ANSWERThere are
special building requirements in addition to the building protection requirements for
buildings in A Zones. Due to wave impacts, V Zones have special building protection
standards in addition to the requirements for A zones.
What is the basic rule on improvements and repairs to existing buildings in the
floodplain? - ANSWERIf the cost of improvements or the cost to repair the damage
exceeds 50 percent of the market value of the building, it must be brought up to
current floodplain management standards.
What is the basic rule on calculating the cost of the damage? - ANSWERSubstantial
damage is determined regardless of the actual cost to the owner. You must figure
the true cost of bringing the building back to its pre-damage condition using qualified
labor and materials obtained at market prices.

What causes a tsunami? - ANSWERUnderwater earthquakes or volcanoes
In a riverine AE Zone with a base flood elevation, what must a developer show in
order to demonstrate that he is meeting Basic Rule #3? - ANSWERHe must conduct
an encroachment review that demonstrates that the cumulative effect of the
,proposed development, when combined with all other existing and anticipated
development:
· Will not increase the water surface elevation of the base flood more than one foot
at any point within the community, and
· Is consistent with the technical criteria contained in Chapter 5 (Hydraulic Analyses)
of the Flood Insurance Study: Guidelines and Specifications for Study Contractors,
FEMA-37, 1995.

What two problems result from floodplain development? - ANSWER1. Development
alters the floodplain and the dynamics of flooding
2. Buildings and infrastructure are damaged by periodic flooding.
What does watershed development do to flooding? - ANSWERThe increase in
impervious surface results in increased runoff and higher flood levels.
What is one of the problems with constructing seawalls to protect buildings from
flooding or erosion? - ANSWERIt can accelerate erosion on properties at the end of
the wall.
What are the five main causes of flood damage? - ANSWER1. Hydrodynamic forces
2. Debris impact

7. Contaminated air from dirty heating ducts
8. Stress and mental health problems
Prior to the 1960s what was the primary way to reduce flood losses? -
ANSWERStructural flood control projects
,What is the Unified National Program for Floodplain Management's definition of
"floodplain management"? - ANSWER"A decision-making process that aims to
achieve the wise use of the nation's floodplains"
What are the two primary goals of floodplain management? - ANSWER1. To reduce
the loss of life, disruption, and damage caused by floods
2. To preserve and restore the natural resources and functions of floodplains
What areas are conductive to flash flooding? - ANSWER1. Hilly area with steep
slopes and narrow valleys
2. Urban areas with large amounts of impervious surfaces and storm sewers
3. Area downstream of dams or subject to ice jams
Is erosion only a threat in coastal areas? - ANSWERNo. Riverine erosion can move
stream channels and undercut structures.
1. Hydrodynamic forces are caused by _______ water and hydrostatic forces are
caused by _______ water. - ANSWERMoving, standing
List three materials or household items that are particularly susceptible to flood
damage by soaking. - ANSWER1. Wood
2. Gypsum wallboard
3. Furniture and upholstery
4. Carpeting
5. Mattresses
6. Books
7. Electrical appliances
8. Gasoline engines
What are examples of non-structural flood protection measures? - ANSWER1.
Regulations to prohibit development in high-hazard areas.
2. Building codes requiring flood-resistant construction for new buildings in flood
prone areas.
3. Acquisition and relocation of buildings in high hazard areas.
4. Installing flood warning systems.
5. Controlling stormwater runoff.
6. Providing self-help advice to property owners.
What is the Unified National Program for Floodplain Management's four main
floodplain management strategies? - ANSWER1. Modify human susceptibility to
flood damage
2. Modify the impact of flooding
3. Modify flooding itself
4. Preserve and restore natural resources
What are the objectives of the NFIP? - ANSWERThe National Flood Insurance Act
created the National Flood Insurance Program (NFIP) to:
1. Transfer the costs of private property flood losses from the taxpayers to floodplain
property owners through flood insurance premiums.
, 2. Provide floodplain residents and property owners with financial aid after floods,
especially smaller floods that do not warrant federal disaster aid.
3. Guide development away from flood hazard areas.
4. Require that new and substantially improved buildings be constructed in ways that
would minimize or prevent damage in a flood.
What are the three basic parts of the NFIP? - ANSWER1. Communities, states, and
Federal agencies use them as the basis for regulating new flood prone construction
2. Insurance agents use them rating flood insurance policies
3. Lenders and Federal agencies use them to determine when flood insurance must
be purchased as a condition of a loan or financial assistance
What should happen to buildings in NFIP communities over time? - ANSWEROver
time, exposure to flood damage should be reduced, as the older pre-FIRM buildings
are replaced by post-FIRM buildings. Eventually a community should have only post-
FIRM building's subject to little or no flood damage.
What is ponding? - ANSWERWhere stormwater runoff collects in depressions and
cannot drain out.
Are plants and animals the only beneficiaries of the "natural and beneficial functions"
of floodplains? - ANSWERNo. People benefit from floodplains through the food they
provide, the recreational opportunities they afford, and the scientific knowledge
gained in studying them. Floodplains also recharge groundwater supplies and their
filtering actions help improve water quality.
What does filling in a floodplain do? - ANSWERFilling reduces the floodplain's ability
to store excess water, sending more water downstream and causing floods to rise to
higher levels.
Does moving sand and sand dunes affect flooding? - ANSWERYes, it may remove a
natural barrier that protects inland properties.
What types of governmental bodies are "communities" by the NFIP? -
ANSWERThese governmental bodies vary from state to state, but can include cities,
towns, villages, townships, counties, parishes, special districts, states, and Indian
Nations with the statutory authority to enact and enforce regulations.
Which FEMA office works directly with communities? - ANSWERThe ten Regional
Offices
What is the Write Your Own Program? - ANSWERAn arrangement whereby private
insurance companies write and service NFIP flood Insurance policies under their
own name.
When a community applies to join the NFIP, what must it submit? - ANSWER1. A
resolution of intent to "maintain in force...adequate land use and control measures"
and to cooperate with FEMA.
2. Its adopted floodplain management ordinance
