Hurricanes, Tropical Depressions, and Floods—Oh My!
October 2008
"Everybody talks
about the weather, but nobody does anything about it."
~Mark Twain, editorial in the
Hartford Courant, August 24, 1897
"Just a reminder
to everyone to please be sure and close all windows in your suite before leaving
today because of high winds and heavy rains predicted for this weekend. Have
a great and safe weekend."

It is October 2008, and the hurricane season still has a month or so to go,
as the "season" is considered to be June 1 to November 30. In September, Hurricane
Gustav narrowly missed New Orleans. Tropical Storm Hanna, Hurricane Ike, and
Tropical Storm Josephine have already made their presence known. Thousands of
private and public organizations in hundreds of U.S. cities and towns braced
for these storms and those yet to come.
Risk management professionals will try to answer the ongoing "what if" questions:
What wrath will such storms bring to the organization? Will our property insurance
be sufficient for potential damage, lost earnings, and increased operating expenses?
Mark Twain's comments from 1897 do not have to ring true. Weather risk management
may be as simple as the loss prevention

Risk management professionals need to talk about the weather to determine what
may happen from any weather condition: exposure identification—step one of the
risk management process. Once the exposures are identified and understood, then
the risk management professional can do
something about the possible outcomes of a weather event.
In this article we review weather events and the use of commercial property
insurance in the post-Katrina insurance marketplace. An organization need not
be in a coastal area to find that its operations are affected by a coastal event
that takes place hundreds of miles away.
Exposure identification
It does not take much in total insurable values in weather-prone areas of
the United States for a property insurer to restrict capacity for windstorm
and flood coverage by reduced limits and mandated specific windstorm and flood
deductibles. Weather-related coverage issues can be further complicated when
an insurance buyer must obtain coverage from not one insurer but several when
insured by a multi-insurer and multi-policy layered program. Weather-related
coverage issues are no longer simply an issue for southern coastal states, but
today impact commercial property insurance buyers along the Gulf and Southern
seaboard, north from Florida to Maine and inland for many miles.
There are many potential risks of loss that may arise from a weather event,
especially when one considers the devastation of wind and flood; one person
cannot assume to identify them all. To understand weather loss exposures, the
risk management professional needs to first
communicate within the insured organization
from operations personnel to facilities management to human resources to those
charged with business continuity and disaster planning.
The Insured Location
This stage of the risk management process is not simply what can happen to
an organization from a weather event but how to quantify or measure the potential
damages. Loss from windstorm or flood may be greater than fire peril for direct
damage, business income (BI), continuation of ordinary payroll, and extra expense.
The surge in demand and an insured's inability to make timely repair of damages
exacerbate the property damage and extend the period of interruption and need
to utilize other means of operations (extra expense).
Demand surge is the hyper/increased cost of supplies and labor after a major
loss event (Hurricane Katrina) when many parties seek and bid for construction
and repair services at the same time—a modern day example of supply and demand.
The greater the area of disaster the greater effect and increased cost of demand
surge.
The quantification issues of risk of loss and subsequent need for insurance
becomes more important to the organization when insurance capacity is limited,
price of insurance is expensive, and the cost of risk includes significant expense
from assumed risk of loss through deductibles and BI waiting periods.
Beyond the Insured Location
Trading partners of the organization, such as critical suppliers and customers,
may not be static and may change as the insured organization continues to evolve.
Supplier and customer changes may introduce new exposures for the risk management
professional to consider especially if the new trading partner or customer locations
are prone to windstorms and flooding. Will a weather loss event at one of these
locations have a significant impact on this organization? Is contingent BI coverage
an appropriate response for this exposure when one considers the severity of
the exposure, available limit, waiting period, and ultimate cost of coverage?
Weather-related utility outages may be experienced through a wide geographic
area and involve many organizations at once. Loss potential cannot be viewed
strictly from an insured's single location but must include the affect of many
organizations within the same event.
- Is utility interruption insurance an efficient and possible solution
for direct damage (perishable goods such as food and medical supplies) and
for BI?
- Are risk control practices more cost effective than insurance? Can the
organization assume a longer waiting period with optimal risk controls in
place?
- Does it make economic sense to purchase power generators prior to a
loss event for onsite power use for an electrical outage?
- Will the organization be able to timely locate, purchase, or lease appropriate
generators after the loss event?
- Generators and related equipment will be subject to demand surge just
like construction commodities such as roof shingles, trusses and wallboard.
- Can any operations be shifted to other location even if the costs of
operation will be greater at that location?
- Is use of alternate sites been factored into business continuity planning?
- Can the business continuity plan help quantify the need and amount for
extra expense coverage?
Will use of alternate sites require changes in the organization's property
insurance?
- Change in values and need for changes in coverage limits as well for
all risks of loss.
- Determine possible increased insurance cost if alternate site is not
equal in physical exposure such as construction, protection, etc.
Weather events can create havoc for everyday transportation which in turn
can affect direct damage and BI recovery.
- Will roadways be closed, routes altered, bridges damaged?
- How will supplies arrive and how will product be sent out?
- Will employees be able to make it to the workplace?
Insurance
The next steps in the risk management process include the determination and
evaluation of techniques that will address weather exposures and risk of loss.
These steps range from risk mitigation strategies such as separation of exposure
units, use of redundant operations, and forms of risk control, such as loss
prevention. For this article, we assume appropriate risk controls (contents
off the floor and out of sublevel storage areas, roofs up to current code, etc.)
have been considered and implemented. Thus, the next step to consider is commercial
property insurance to address potential loss from coastal weather events.
Perils—Flood and Wind
When we speak of coastal weather events, we need to focus on the perils of
flood and windstorm. The definitions of these two perils must be understood
to determine how coverage, limits, and deductibles may affect the insured organization
after a weather event. Understanding these definitions is critical since there
are definite distinctions between loss caused by flood and loss caused by windstorm.
Further distinctions are made for coastal area windstorms and the use of the
term "named storm" or "named windstorm."
As the intensity of the wind increases, so does the potential for flooding.
This is an important issue for the risk management professional to consider
as the increased threat of flood, even when the cause is wind, is still considered
flood and not windstorm for purposes of coverage. Flood and windstorm, especially
when arising out of tropical storms and hurricanes, create unique losses that
may result in loss settlement disagreements between insured and insurer.
Much discussion, heartache, and litigation has resulted from catastrophic
storm damage such as that which resulted from Hurricane Katrina. The need to
understand the differences between "flood" and "windstorm," as well as coverage
conditions, limitations, and exclusions must occur prior to loss. Understanding
flood coverage is especially time critical since commercial insurers may not
bind coverage as a storm is declared to be imminent, and coverage sought from
the National Flood Insurance Program (NFIP) in most cases will impose a 30-day
coverage waiting period once coverage is bound.
Flood
Flood exposures can be deemed nominal to severe and are subject to specific
terminology to categorize the physical location of building and contents and
the susceptibility to flooding. The categories are created and monitored by
Federal Emergency Management Agency (FEMA) for the NFIP.
Flood hazard areas are identified on the Flood Insurance Rate Map as a Special
Flood Hazard Area (SFHA). SFHA are defined as the area that will be inundated
by a flood event having a 1 percent chance of being equaled or exceeded in any
given year. The 1 percent annual chance flood is also referred to as the base
flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones
A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30,
Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood hazard areas, labeled
Zone B or Zone X (shaded) are the areas between the limits of the base flood
and the 0.2-percent-annual-chance (or 500-year) flood. The areas of minimal
flood hazard, which are the areas outside the SFHA and higher than the elevation
of the 0.2 percent annual-chance flood, are labeled Zone C or Zone X (unshaded).
Information in this paragraph is taken from the
FEMA website.
The risk management professional needs to know what flood zone category is
used for the organization's locations in order to understand flood coverage
that is available from the insurer (whether NFIP or other): limit and deductible
that may differ by location/zone and the need for specific coverage from NFIP
depending on the exclusion used in the property policy.
Flood loss is usually excluded in any preprinted, standard-type property
insurance policy. Depending on the flood exposure an organization may be able
to purchase flood coverage from the property insurer and have coverage endorsed
onto the policy. A typical exclusion, as used by Insurance Services Office,
Inc. (ISO), in its commercial property policy CP 10 30 04 02, states the following:
We (the insurer) will not pay for loss or damage caused directly or indirectly
by any of the following. Such loss or damages is excluded regardless of
any other cause or event that contributes concurrently or in any sequence
of the loss …
g. Water: (1) Flood, surface water, waves, tides, tidal wave, overflow of
any body of water, or their spray, all whether driven by wind or not.
What is covered when an insured purchase flood coverage? It will depend on
the insurer and wording used. We will examine flood coverage endorsement ISO
CP 10 65 10 00. Are there any apparent differences between the ISO flood exclusion
and the ISO coverage endorsement? Yes. The main difference is the peril of wind
is not mentioned in the ISO coverage endorsement. Does this mean that flood
caused by windstorm ("overflow of inland or tidal water") is covered in the
CP 10 65 10 00? Yes. Overflow of inland or tidal water whether caused by deterioration
of a dam or by storm surge from hurricane is still flood.
Not all flood coverage is the same; the definition of "flood" may differ
by insurer especially if non-ISO policy forms are used or coverage is obtained
from NFIP. These differences may to lead to loss settlement issues and unrealized
coverage expectations of the insurance buyer. Can these differences be minimized?
Maybe, but first the risk management professional has to understand the differences.
While it seems that the overall intent of flood coverage is the same, there
are differences in each definition which may cause one definition to provide
coverage while another may not. The differences pose even greater problems when
several policies and layers are used to arrange overall property insurance.
Whenever possible, the flood definition should be the same in the primary and
excess layers. If not, then provision needs to be made for the differences to
limit excess attachment points.

ISO CP 10 65 10 00
The following is added to the Covered Causes of Loss: Flood, meaning
a general and temporary condition of partial or complete inundation of normally
dry land area due to: 1. The overflow of inland or tidal water; 2. The unusual
or rapid accumulation or runoff of surface waters from any source; 3. mudslides
or mudflows, etc.
-
Admitted policy insurer
Flood; surface waters; rising waters; waves; tide or tidal water; the
release of water, the rising, overflowing or breaking of boundaries of natural
or man-made bodies of water; or the spray there from; or sewer back-up resulting
from any of the following; regardless of any other cause of event contributing
concurrently or in any other sequence of loss.
-
Non-admitted insurer
Flood shall be defined as follows: Surface water, waves or tidal water
and the rising (including the overflow or breaking of boundaries) lakes,
ponds, reservoirs, rivers, harbors, streams, or similar bodies of water,
all whether wind driven or not; mudslide or mudflow; water that backs up
from any sewer or drain; any release of water impounded by a dam.
-
NFIP General Property Form—Standard Flood
Insurance Policy
A general and temporary condition of partial or complete inundation of
two or more acres of normally dry land area or of two or more properties
(at least one of which is your property) from: overflow of inland or tidal
waters; unusual and rapid accumulation or runoff of surface water from any
source; mudflow (note that term "mudflow" is
further defined); collapse or subsidence
of land along the shore of a lake or similar body of water as a result of
erosion or undermining caused by waves or currents of water exceeding anticipated
cyclical levels that result in a flood as defined … above.
Differences in definition may not be the only dissimilarity in coverage.
This becomes apparent when we look to NFIP as an underlying flood policy with
excess coverage by a commercial property policy or when coverage is arranged
by multi-layer excess commercial property policy(s). What are other coverage
issues?
-
NFIP values loss on actual cash value—not replacement cost. The difference
in valuation may lead to a coverage gap if the next coverage layer is on
a replacement cost basis. An insured can request that the primary property
policy provide flood coverage excess of the maximum provided by NFIP. This
way the difference in valuation gap may be minimized.
-
NFIP provides direct damage only—no provision for business income or
extra expense coverage.
-
NFIP maximum coverage limits of $500,000 per building and $500,000 contents
per building may not be sufficient to "fill-in" the deductible of the primary
property insurer.
A key challenge to the risk management professional is to quantify the possible
loss from flood, including any additional flood exposure, such as storm surge
which may be created by windstorm. While capacity for flood limits may not be
sufficient or even affordable, it is essential for the insured organization
to understand the catastrophic loss potential of a flood event and the need
for recovery funds from sources other than property insurance.
Windstorm
Windstorm is normally a covered peril whether an organization purchases "named
peril" or "all risks of loss" coverage. Damage that results from windstorm caused
flood is still considered damage from flood for purposes of coverage, limits,
and deductibles. When may "wind" become "windstorm" for purposes of commercial
property insurance? The answer is when it is given a name by either the National
Hurricane Center (NHC) or National Weather Service. The devastation capability
of a coastal windstorm has resulted in the property insurance term of "named
storm" or "named windstorm."
An insurer's reasoning is to separately define coverage for damage by "generic"
wind from that of a coastal weather event such as a hurricane. What is a coastal
windstorm? Let's start with information published by the
National Hurricane
Center (NHC).
Hurricane is a type of tropical
cyclone, which is a generic term for a low pressure system that generally forms
in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern
Hemisphere, a counterclockwise circulation of winds near the earth's surface.
Tropical cyclones are classified as follows:
-
Tropical Depression is an organized
system of clouds and thunderstorms with a defined surface circulation and
maximum sustained winds* of 38 mph or less.
-
Tropical Storm is an organized system
of strong thunderstorms with a defined surface circulation and maximum sustained
winds of 39-73 mph.
-
Hurricane is an intense tropical weather
system of strong thunderstorms with a well-defined surface circulation and
maximum sustained winds of 74 mph. Hurricanes are categorized by the Saffir-Simpson
Hurricane Scale.
Category 1 Hurricane—winds
74-95 mph. No real damage to buildings. Damage to unanchored mobile homes. Some
damage to poorly constructed signs. There may be some coastal flooding and minor
pier damage.
Category 2 Hurricane—winds
96-110 mph. Some damage to building roofs, doors and windows. Considerable damage
to mobile homes. Flooding damages piers and small craft in unprotected moorings
may break their moorings. Some trees blown down.
Category 3 Hurricane—winds
111-130 mph. Some structural damage to small residences and utility buildings.
Large trees blown down. Mobile homes and poorly built signs destroyed. Flooding
near the coast destroys smaller structures with larger structures damaged by
floating debris. Terrain may be flooded well inland.
Category 4 Hurricane—winds
131-155 mph. More extensive curtain wall failures with some complete roof structure
failure on small residences. Major erosion of beach areas. Terrain may be flooded
well inland.
Category 5 Hurricane—winds
156 mph and up. Complete roof failure on many residences and industrial buildings.
Some complete building failures with small utility buildings blown over or away.
Flooding causes major damage to lower floors of all structures near the shoreline.
Massive evacuation of residential areas may be required.
When winds from these storms reach 39 mph, the cyclones are
given names. Storm names are used to facilitate geographic referencing, for
warning services, for legal issues, and to reduce confusion when two or more
tropical cyclones occur at the same time.
What happens to property insurance when a storm becomes "named"? It will
depend on the policy and the insurer, but usually a separate deductible will
apply to loss. In some cases, a sublimit for windstorm damage will also apply.
Named windstorm deductibles will usually apply as a percentage of the total
insurable values (building, contents, and business income) at, within, or attributed
to any one building. Depending on the risk of wind loss, the percentage deductible
may be subject to a minimum dollar amount. Infrequently insurers will offer
a maximum deductible for loss arising out of named windstorm. The deductible
wording must be reviewed carefully to ensure the percentage applies only to
the damaged building(s) and not all total insurable values at the covered location.
An insured organization may find it has assumed significant exposure to coastal
wind loss via percentage deductible and if coverage is subject to sublimit.
Much like the peril of flood, the risk management professional should try to
quantify the total loss that may occur from a catastrophic windstorm.
Dissimilar Coverage Terms
Difference in flood and windstorm coverage terms may lead to attachment problems
between primary and excess layers. Some of the coverage issues can be addressed
through use of "priority of payments" wording. This type of endorsement is used
to ensure the excess insurer will recognize erosion of underlying coverage by
policy terms broader than that provided in the excess policy. While the underlying
erosion is recognized by the excess insurer, it will only pay claims in its
layer of coverage that are (1) excess of its attachment point and (2) that are
covered by the terms of its excess policy. Priority of payments may be stated
as follows:
Any recoveries made under the primary policy shall be considered as first
applying to those perils and/or coverages not insured against by this policy.
Upon exhaustion of the primary policy limits, this policy shall drop down
and be liable for loss in excess of the amount attributed to the primary
policy as respects those perils and/or coverages insured hereunder subject
to the limit of this policy.

insurance programs are reviewed in more detail in IRMI's "Layered Property Insurance,"
The Risk Report, Volume XXX, No. 3, November
2007.)
Conclusion
Risk of loss from coastal weather events may be greater than loss from perils
such as fire, explosion, or equipment breakdown. Property insurers address flood
and windstorm exposures through specific definitions, limitations, and exclusions.
Policy coverage must be understood well in advance of any storm-hurricane, tropical
depression, or flood. Coverage needs and expectations must be addressed pre-loss
and not attempted after the loss event through litigation. An important part
of the risk management process is RTP: Read The Policy.
