ENGINEERING :: FLOODPLAIN / ELEVATION
What
is a 100-year floodplain?
It is the
area of land inundated by floodwaters from a storm that has a one
percent (1%) probability of being equal at or exceeded in any given
year.
What is the difference between FEMA designated zones A, AE, and
X?
Zone A is an
area of the 100-year floodplain that has not been studied in
sufficient detail to determine the water surface elevation of the
100-year flood. Zone AE is the area of the 100-year floodplain with
the elevation of the 100-year flood available and the floodway
designated. Zone X is an area inundated by the 500-year storm or
areas outside of land inundated by the 500-year storm.
Who do I need to speak with to construct something in a
floodplain?
Please
contact the City's Department of Public Works receptionist at
817-459-6550 and she will forward your inquiry to the appropriate
staff person.
What is the floodway?
The area of
the channel of a creek and the adjacent land areas that are reserved
for flood flows. This area is to be clear of fences, buildings,
fill, or any other obstructions that could inhibit flood flows.
How do I get an elevation
certificate?
The City no
longer provides elevation certificates. You may contact an engineer
or surveyor of your choice to obtain an elevation certificate.
I have never been in a floodplain before and my property has
never flooded but now my mortgage company and/or insurance provider
is wanting me to secure flood insurance because my house is now
designated in the floodplain.
Usually this
is caused by a refinance, replat, or add-on construction requiring a
building permit. This can also be caused by updated FEMA flood
maps. One solution to this issue is to secure an Elevation
Certificate. If the Elevation Certificate states that your
slab is high enough above the floodplain, you may satisfy your
mortgage lender or qualify for reduced insurance rates.
I have
specific floodplain questions concerning my Arlington
property. Who do I contact to have my questions answered?
Please
contact the Department of Public Works at 817-459-6550.
Where can I find information and
answers to general floodplain questions on protecting my home from
flooding?
