1968, Congress created the National Flood
Insurance Program (NFIP) to provide affordable
flood insurance to people who live in areas with the
greatest risk of flooding; this area is called the Special
Flood Hazard Area (SFHA). The NFIP makes federally
backed flood insurance available in communities that
agree to adopt and enforce floodplain management
ordinances to reduce future flood damage. This is
important since property owners must purchase flood
insurance for property located within a SFHA.
The Community Rating System (CRS) is a program
developed by the Federal Insurance Administration
to provide incentives for NFIP communities that
implement more stringent floodplain standards than
the minimum NFIP requirements. The CRS rewards
these efforts with discounts on flood insurance
premiums. The city of North Miami currently holds
a Class 5 CRS rating. This classification equates to a
25% discount on new or renewing flood insurance
policies for all SFHA properties and a 10% discount
on policies for non-SFHA properties.
In North Miami, there are approximately 6,100 flood
insurance policies in effect. Annually the city’s CRS
Class 5 rating generates over $900,000 in savings on
flood insurance premiums. Since flooding is the most
common natural disaster, it is important that you
obtain the maximum protection.
You can purchase flood insurance no matter
where you reside (in a high, moderate or low risk
area) and there is no exclusion based on the type
of ownership you represent (i.e. homeowner, renter
or business owner).
Since protecting your property from floods
is important, the following information and tips
may be of interest to you. Please refer to this fact
sheet in the event of an impending hurricane,
tropical storm or notification of projected heavy
rainfall. During extended periods of heavy rainfall,
low lying areas within the city are subject to
flooding. This information is offered to help
protect your property and reduce potential losses
due to flooding.
Arch Creek, Little Arch Creek, Biscayne Canal
and Oleta River are the four major waterways that
traverse the city of North Miami. The majority of our
storm sewer system empties/discharges toward one
of these four waterways or Biscayne Bay, which
connects directly with the Atlantic Ocean. The waterways
are influenced by tides that contribute to
drainage and flood problems in the city. When there
is a high tide or heavy rainfall, the storm sewer
system will rapidly fill up from surface run-off and tidal
waters; this could cause flood conditions in our streets,
swale areas and lawns.
The city of North Miami can be divided into two
major drainage areas, (1) the area west of the Biscayne
Canal, and (2) the area east of the Biscayne Canal.
The area west of the Biscayne Canal has primarily
sandy soil and a very low water table elevation. The
remainder of the City, east of the Biscayne Canal,
consists of muck, marl and sand and primarily has
high water table levels.
Your property may be elevated high enough that
you have not experienced flooding. However, this may
change in the future. Hurricane Andrew (1992), South
Florida’s most devastating storm was not a wet
hurricane as compared to Hurricane Irene (1999) which
registered 13 inches of rain in Miami-Dade County
in a 24-hour period. In 2000, continuous rainfall from
the October 3 ”No Name” storm deposited more than
19 inches of rain in a 24-hour period. This storm
inundated local canals and waterways and caused
unprecedented residential property damage and
destruction for what was originally forecast as a severe
|Flood Warning System
The City of North Miami and Miami-Dade County
utilize the National Weather Service (NWS) for flood
notification. The NWS will issue flood advisories at least
six (6) hours prior to expected heavy rainfall that could
cause the drainage systems to overflow and create
inland ponding of flood waters and the isolation of
residential/business areas. Remain tuned to your
local radio stations for up-to-date forecasts. In 2001, the City developed a citywide flood warning plan to
provide early warning to neighborhoods that might
experience flooding. Police vehicles will drive through
the neighborhoods that may be impacted and use
their sirens and loud speakers to issue warnings.
Evacuation routes will be US Highway 1 (Biscayne Boulevard),
NE 125 Street, NE 135 Street and Interstate 95.
Flood Safety: If you are advised to evacuate, turn off your
utilities at the main switches and/or valves. Disconnect
electrical appliances, but do not touch any electrical
equipment if you are wet or standing in water. Do not
walk or drive through standing or flowing water; there
may be a downed power line, sinkhole or even a canal
that you are unable to see. Watch your step in flooded
areas as slip and fall accidents are one of the leading
causes of injuries after a storm.
Flood Insurance: Most mortgage lenders require flood insurance
based on the elevation of the property. In the event
that your mortgage does not have this provision or
if you own your property free and clear, you can still
purchase this insurance at any time; however, there
is a 30-day waiting period before the policy becomes
effective. Remember, neither homeowner’s nor
windstorm insurance covers flood damage to
structures. Since North Miami is an NFIP community,
flood insurance is available to protect all homes,
condominiums, apartments and non-residential
buildings (including commercial structures) within
the City. You are eligible for flood insurance, regardless
of whether your property has never flooded or
has flooded several times in the past. All properties
secured by a federally backed mortgage (FHA, VA,
FNMA, etc.) must carry flood insurance.
Floodplain Development Permit Requirements: All buildings under construction require permits.
These permits should be obtained prior to commencement
of construction activities. Contact the Building
and Zoning Department before you build, alter,
regrade or add fill to your property. Building and
Zoning is located at 12340 NE 8 Avenue. If you see
building or fill being added to a property without a
City permit posted, report the work to 305.895.9820.
Substantial Improvement Requirements: The City of North Miami and the National Flood
Insurance Program require that if the cost of
reconstruction, rehabilitation, additions or other
improvements to a building equals or exceeds 50
percent of the building’s market value during a fiveyear
period, the building must meet the same
construction requirements as a new building. This
includes elevating the lowest floor to current
standards. Substantially damaged buildings must also
be brought up to the same standards.
Drainage System Maintenance:Proper drainage helps reduce the risk of flooding.
It is illegal for any direct or indirect entry of any solid,
liquid or gaseous matter to enter the drainage system.
The City inspects the drainage system on a regular
basis and removes blockages that are found or
reported. If you live near areas where waters flow, you
can help in this process by keeping the banks clear of
brush and debris. Reports of any violations should be
made to the Public Works Department at 305.895.9830.
Natural and Beneficial Functions: The Oleta State Recreation Area and Mangrove
Preserve, located between NE 135 Street and NE 163
Street and east of US Highway 1, has been designated
as Environmentally Sensitive Land. These undisturbed
natural areas of North Miami act as a natural storage
area for flood waters; this helps reduce the possibility
of flooding to nearby residences while helping to
recharge the groundwater aquifer. Please help keep
this area natural and beautiful by reporting any illegal
dumping and littering violations to the City’s Public
Works Department at 305.895.9830 or Miami-Dade
County at 311.
Map Determinations: The City provides Flood Insurance Rate Map (FIRM)
determinations to let you know if you are in a flood
hazard area and if you are required to carry flood
insurance. If you would like a determination, contact
the Building and Zoning Department at 305-895-9820.
You can also refer to the City floodzone map to
determine if your property lies in the Special Flood
Site Visits: Upon request, a representative from the North
Miami Public Works Department will visit your
property to review flooding problems and to explain
possible ways to alleviate and prevent flood damage.
Also, if you have experienced flooding, drainage, sewer
backup problems, or have seen illegal dumping of
debris into City canals, lakes, or storm drains,
please contact the Public Works Department at
|Flood Protection Tips
Protecting your Property: If your lot is large enough, you should consider
regrading it or building a small floodwall. You can also
place watertight closures over the doorways; however,
these approaches only protect if flooding is not too
deep. You can also consider elevating your home.
Flood-proofing, installing floodgates and making
walls waterproof are among the common ways
to structurally protect commercial property. Most
times, residential structures are elevated higher then
the anticipated floodwaters. For additional assistance
on how to protect your property from flooding,
you may contact the North Miami Public Works
Department at 305-895-9838, or you may contact
the City’s Building Official at 305-895-9820.
Additional information on how to perform residential
retrofitting or commercial flood proofing is available
at the North Miami Public Library in the City’s
Floodplain Management (CRS) reference section.
Minimizing Flood Damage: Don’t throw or dump anything into storm sewers
or canals within the City. Even grass clippings and
branches can accumulate and plug channels and
drains. A plugged channel or storm drain cannot carry
water when it rains. Clogged storm drains will cause
water to back up into the street and may cause
flooding. Every piece of trash contributes to flooding.
If your property is next to a canal, help keep the
banks clear of brush and debris. The City has a canal
maintenance program which can help remove major
blockages such as downed trees; please report any
blockages to 305.895.9830.
Do not walk through flowing water, or drive through a flooded area: Drowning is the number one cause of flood deaths.
Currents can be deceptive; six inches of moving water
can knock you off your feet. If you walk in standing
water, use a pole or stick to ensure that the ground is
still there. Also do not disregard road barriers, the road
or bridge may be washed out.
Stay away from power lines and electrical wires. Electrocution is the number two flood killer.
Electrical currents can travel through water. Report
downed power lines to Florida Power and Light; the
number is 305-442-8770. You can also report downed
power lines to the North Miami Police Department
Have your electricity turned off by FPL. Some appliances, such as television sets, hold
electrical charges even after they have been
unplugged. Avoid using appliances or motors which
have gotten wet unless they have been taken apart,
cleaned and dried.
Be ready for the unexpected. Place important documents inside plastic bags
or other waterproof containers. Review your
insurance policy to ensure it provides adequate
coverage. Know what type of coverage you have.
Most policies cover wind storm damage, but not
flooding. Any policy change usually takes 30 days
before going into effect.
Look out for animals, especially snakes. Small animals that have been flooded out of their
homes may seek shelter in yours. Use a pole or stick to
poke and turn things over and scare away small
animals. Even domesticated animals may react differently
after a disaster or storm and could bite or attack.
Look before you step. After a flood, the ground and floors are covered
with debris, including broken bottles and nails. Floors
and stairs that have been covered with mud can
be very slippery.
Be alert for gas leaks. If you use natural gas, use a flashlight to inspect
for damage. Don’t smoke or use candles, lanterns or
open flames unless you know the gas has been turned
off and the area has been ventilated.
If you must evacuate: If you are required to evacuate, try to move to
the house of a friend or family member not affected by
the impending high waters. If you live in a mobile
home, or are electrically dependent, plan to evacuate
at the first notice of the emergency conditions.
Rehearse your evacuation plan with all household
members. Plan to leave early to avoid any traffic delays.
Register with the Miami-Dade County Emergency
Evacuation Assistance Program at 311 or TDD at
305-468-5402 if you will need assistance to evacuate.
Discuss these tips with your neighbors and friends.
Try to have a prearranged plan designating how you
can contact your neighbors. If you have to evacuate,
inform each other of places where you will be staying
and leave contact telephone numbers and addresses.
Securing Boats: If you own a boat, it’s your responsibility to secure
it. As a boat owner, you should make a plan in advance
to move your boat or arrange for its storage. Check
with a local marina for suitable alternatives. If possible,
store it inside a garage or warehouse. If you must leave
your boat outside, attach the trailer tongue to something
firm in the ground, let the air out of the tires and
make sure the boat is secure to the trailer. If possible,
fill the bilge with water, which adds extra weight.
If you plan to keep your boat in the canal, be sure to double the dock lines, leaving sufficient space for the
tidal range and put out extra anchors. Don’t forget to
remove all marine electronics or other unsecured
equipment. Sail boaters should remove self-furling
sails and Bimini tops. Boats on davits should be
secured with extra tie lines and in such a manner to
keep the boat from swinging during high winds.
Pet Safety Tips: Remember, most evacuation centers will not
accept pets. So make plans in advance to board your
pets in an animal kennel or with friends. If you plan
to ask a friend, be sure to ask in advance. Make
certain that your friend lives in an area that is not
expected to be affected by the storm. Ask if their home
would be open to you and/or your pet should a storm
threaten. Do not leave your pet home during a
hurricane. A secure room and a few days food and
water do not necessarily mean safety for your pet.
Many people returned home after Hurricane Andrew
to find their pets missing. Keep a current picture
of your pet to help identify it. After the storm, take
caution in allowing your pet outdoors after the storm
has passed. Familiar scents and landmarks will have
been altered and your pet may become confused or
lost. Downed power lines also present real dangers.
Take precautions not to allow your pet to consume
food or water which may have become contaminated.
