In 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 over 6,000 flood insurance policies in effect. Annually the city’s CRS Class 5 rating generates over
$1 million 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 area thunderstorm.
|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), 125 Street, 135 Street and Interstate 95.
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.
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. 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 five-year 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.
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 flood zone map to determine if your property lies in the Special Flood Hazard Area.
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 305.895.9838.
|Flood Protection Tips
Protecting your Property:
If your lot is large enough, you should consider regarding 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 at 305-891-8111.
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.
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
