Periodically,
rivers, streams and lakes will overflow their banks
and inundate adjacent land areas. These areas, known as
floodplains,
temporarily store this excess water. Flood damages occur
only when man
interferes with the natural flooding process by altering the
watercourse, developing areas in the upper watershed, and/or
building
inappropriately in the floodplain itself.
The traditional solution to flood problems has been to
build
structural protection works such as dams, diversions, levees
and
floodwalls. Despite tremendous expenditures for these
structural
projects, economic flood losses have continued to increase
year after
year. Given this, governments at every level have begun to
see the
solution to avoiding flood damages lies not in keeping the
water away
from people, but rather in keeping people away from the
water. This
philosophical shift lead to the creation of the National
Flood
Insurance Program (NFIP) in 1968, thereby codifying the
concept of
floodplain
management.
The base flood,
sometimes
referred to as the 100-year flood, has a 1% chance of
occurring in any given
year. Although a 100-year flood sounds remote, keep in mind
that over
the life of an average 30-year mortgage, a home located
within the
100-year
flood zone (A or V zone) has a 26% chance of being inundated
by the
base flood. This same home has less than a 1% chance of fire
damage
during the same period.

FIRM Panels. To find out which Flood
Panel a property is within, this map will show the
new panels (effective September 3, 2010). Once the
panel number
is known then that panel can be viewed by going to the
directory below
for the official FEMA FIRM Panel.
CURRENT
UMATILLA
COUNTY FIRM PANELS (Effective September 3,
2010) Now the
whole County is being shown
on the same Index map
with no individual maps for the cities or the
Tribe. The folder
that contains
the 2010 Panels contains all of the new panels that are
now effective
as of
September 3, 2010. These new panels have the 2006
NAIP imagery
as the base layer which shows structures and other
features.
The
Milton-Freewater Area
will
have a large area placed in the Special Flood Hazard
Area, Zone AO
(Areas of Shallow Flooding). The associated map
shows the
Milton-Freewater Special Flood Hazard Areas.
A
Flood Insurance Study (FIS) is a book that contains
information
regarding flooding in a community and is developed in
conjunction with
the Flood Insurance Rate Map (FIRM). The FIS, also known as
a flood
elevation study, frequently contains a narrative of the
flood history
of a community and discusses the engineering methods used to
develop
the FIRMs. The study also contains flood profiles for
studied flooding
sources and can be used to determine Base Flood Elevations
for some
areas.
NEW
FLOOD
INSURANCE
STUDY
(Effective September 3, 2010).
The
Flood Insurance Study that has been completed for the new
FIRMs is
now available for review. This FIS will be effective
September 3,
2010 but is here for reference. The new FIS brings all
of the
County and Incorporated Cities and the CTUIR (Tribe).

Letter
from
FEMA
There have been a number of Letter of Map Changes (LOMC)
issued over
the past several years. These documents will modify
the FIRM
Panels and will affect flood insurance for the parcels
involved.
Therefore, the documents are important to keep track of and
on file in
case there is any question as to the status of flooding on
the affected
parcel(s).
COUNTY
LOMA LIST, dated August 18, 2010 dealing with "Valid LOMC for
Umatilla County" for unincorporated areas of the
County.
Authorized Letter of Map Changes do not show up on the
official Flood
Insurance Rate Maps (FIRMS) so this listing is very
important to prove
that the LOMC has been authorized and flood insurance is not
required.
