FIRM’s Assertion

Most models predict that the highest windstorm insurance rates in the state should be charged in Monroe County.Actual experience does not support these high rates.The models do not accurately reflect the realities of Monroe County and thus inaccurately predict our risk.

Strike Probabilities

Strike Probabilities vary based on data sets, time frames and other criteria used by statisticians. While Monroe County may be more vulnerable to tropical activity than other areas, the magnitude of the difference in vulnerability is not as great as models and windstorm insurance rates would suggest.

According to an historical study by Florida State University, low intensity storms occur in the Keys about as frequently as in panhandle counties, and higher intensity storms occur more frequently in other southeast Florida counties than in Monroe.

Note that according to this study, no Category 5 storms occurred anywhere other than Monroe. Hurricane Andrew was a Cat 5 storm that hit Miami-Dade in 1992. Data used in modeling should be fully vetted for accuracy.

Assertion & Recommendation

Actual wind claims are lower in Monroe County due to a combination of engineering, meteorological and geographical factors. Thus, rates in Monroe County should not be the highest in the state.The FPHM and private models that are employed in rate-setting do not adequately reflect Monroe County realities.Proposed changes to modeling standards would address these issues for Monroe and other coastal barrier communities.

Impact of Non-U.S. Land Masses on Intensity: Cuba

The 100-mile coastline of the Florida Keys has been hit by a Category 5 storm only once, in 1935.The mountains of Cuba are 90 miles away from the Florida Keys. Mountainous regions create frictionand generally reduce the intensity of storms that pass over them, and this has frequently been the case in the Keys. Ninety miles is too short a distance over open water for most storms to re-build in intensity.

Impact of Non-U.S. Land Masses: Cuban Mountains

There are three mountainous areas of Cuba in particular that can weaken a storm that crosses over them.

Impact of Non-U.S. Land Masses:

Hurricane Charley 2004Charley originated from a tropical wave, developing into a tropical depression on August 9 about 115 miles south-southeast of Barbados. The depression strengthened within a low-shear environment to a tropical storm early the next day in the eastern Caribbean, and became a hurricane on the 11th near Jamaica. Charley's center passed about 40 miles southwest of the southwest coast of Jamaica, and then passed about 15 miles northeast of Grand Cayman as the hurricane reached category 2 strength on the 12th. Charley turned to the north-northwest and continued to strengthen, making landfall in western Cuba as a category 3 hurricane with 120 m.p.h. maximum winds. Charley weakened just after its passage over western Cuba; its maximum winds decreased to about 110 m.p.h. by the time the center reached the Dry Tortugas around 8 am on the 13th.

Local Building Codes & Conventions

Monroe County has had the strictest building code for all construction (residential, commercial-residential, and commercial) in the state for the longest period of time.

As of 1982, the Standard Building Code required Monroe County to have the state’s highest windspeed rating for a 3-second gust.Since 2002, Monroe County structures have been constructed and renovated to withstand 150 MPH gusts.Shutters are the norm, not the exception, in the Keys, and have been required for all new construction in Monroe County since 1990.

Metal Roofs

Metal roofs have been proven to be more wind-worthy than shingle or asphalt roofs which are standard in the Florida Building Code.

Keys construction conventions require plywood rather than manufactured products as the sheathing material.Metal roofs are more impervious to UV degradation than other materials.V-crimp metal roofs do not produce wind-borne debris to the extent that shingle or tile roofs do.

Development Constraints

Development in Monroe County is subject to a Rate of Growth Ordinances (ROGO).

A limited number of permits is issued yearly.Property owners earn “points” to help them qualify for building permits.Prior to adoption of the FBC in 2002, building to meet and exceed standards for wind-worthiness helped property owners earn more ROGO points.

Sturdy Older Structures

Further, at least half of these homes have been substantially reinforced during renovation with the addition of features such as hurricane clips, creating a much younger effective age than “age of home” (determined by original construction date) would suggest. When homes are significantly remodeled, they must meet current building codes.

Average year of construction for all Keys homes: 1976Average effective age of all Keys homes: 11 years

SOURCE: These ages were calculated from data provided on August 28, 2008 by the Monroe County Property Appraiser’s office from data collected 1900 through 2008. “Effective age” takes into account significant renovations such as new roofs, kitchen/bath remodels, etc.

Height Restrictions

Monroe County’s Comprehensive Plan places a 35-foot limit on building height in the Keys. The only exceptions to this regulation are equipment towers and certain equipment on the roofs of commercial structures.Most residential structures in Key West, the most densely populated area of the Keys, are under 25 feet tall.Wind speeds are measured at 10 meters (~33 feet), and intensify with increasing height.

Wind vs. Storm Surge Losses

The Keys are a low-lying chain of islands, with the highest elevation at 14 feet. (1)

According to meteorologists at the National Weather Service, thegreatest threat to the Keys from Category 3 and higher hurricanes predicted by SLOSH models is from storm surge, not wind. Any wind damage that would occur would be washed away by the surge.(2) Thus, flood insurance would pay first and most for the greatest portion of damage occurring from a significant hurricane.Wilma, a storm many consider to be the “100-year storm,”demonstrated this.

Wind vs. Storm Surge Losses: SLOSH Model

Storm surge predictions are generally based on the SLOSH Model. This model does not necessarily work in the Keys.

The SLOSH model covers inland areas. The Keys have none.The SLOSH model does not take into account the wave action that we experience in the Keys due to our low elevation.Experience in direct-hit storms bears this out:

Storm SLOSH Predicted Surge Actual Experienced Surge

Not Named 1919 8 feet 14 feet

Not Named 1935 9 feet 20 to 24 feet

Hurricane Donna 8 feet 12 to 14 feet

Models predicting surge based on the SLOSH model may under-predict flooding in the Keys, thus leading to over-prediction of wind damage.

Much of the damage from Hurricane Donna was caused by storm surge.

When storm surge (flood) and wind both cause damage, flood pays first.

Wind vs. Storm Surge Losses: Hurricane Ike 2008

The Bolivar PeninsulaIf you take a ferry from Galveston northeast across the Galveston Bay inlet, you arrive at the small town of Port Bolivar, which sits at the end of the 25 mile-long Bolivar Peninsula. Since the peninsula was situated on the right front side of Ike's eye, it took the worst of the storm. The Hurricane Hunters measured 110 mph winds at the shore when Ike made landfall, and Ike's highest storm surge hit the peninsula. The exact height of the storm surge is unknown, since there were no tide gauges there. Based on reports of a storm surge of 11 feet at Galveston Island and 13.5 feet at the Louisiana/Texas border, it is likely that storm surge heights along the Bolivar Peninsula were 15 feet or higher. Photos taken by the Coast Guard yesterday (Figure 2) of the Bolivar Peninsula show damage characteristic of a 15+ foot high storm surge--homes washed off their foundations and completely destroyed. The hurricane probably cut new channels through the peninsula, and it will be difficult for rescuers to reach the area.

Geographic Factors:Linear GeographyDue to the 120-mile long linear geography of populated and insured Monroe County, it is likely that a storm could impact one area of the chain and not impact another at all. PML calculations should take this into account.

Geographic Factors:Category 1 Storm Tracks

Historically, only two category one storms have taken a track that would make landfall in the Keys more than once: Floyd and Inez.

SOURCE: NOAA Coastal Services Center, http://maps.csc.noaa.gov/hurricanes/viewer.html

Actual storm tracks suggest that it is unlikely that a single storm will equally impact the entire island chain. Assertions that storms routinely “track” along US1 in the Keys and thus impact all the insured properties in Monroe County are not supported by experience.

Geographic Factors:Unpopulated Geography

The bulk of the land of Monroe County is the unpopulated Everglades on the mainland. Storms that come within 62 statute miles of this area of the County could be over 200 miles from the populated area of the Keys. This should be taken into account when calculating proximity of land-falling hurricanes.

Pale pink area represents Monroe County. Mainland area is in the Everglades.

Geographic Factors: “Gates”

At least one model utilizes “gates” in evaluating storms that fall within a certain distance from a segment of coastline.Most counties have only a single “gate” or even share a gate with a neighboring County.SOURCE: RMS Inc.

Is Monroe County being

“over-counted”when evaluating

storms that come within 62

NM of its “gates”?

Geographic Factors: “Gates”

Monroe County has four gates, of which:

Gate 27 runs along the coast of uninhabited Monroe.Gate 28 extends south into the Florida straights. No other county has a gate that runs perpendicular to its coast.Gate 29 extends far west of the Florida Keys. Gate 30 represents the linear coastline of the Florida Keys.

ConclusionModels should be adjusted to take into account specific

factors to more accurately predict risk for Monroe County. There is considerable legislative and operational precedent for treating Monroe County separately.

Since 1973, Monroe County has been designated an Area of Critical State Concern, subject to unique development regulations.The Pilot Project in 2006 allowed the Office of Insurance Regulation to consider Monroe County’s insurance rates differently, as there was no reasonable degree of competition for windstorm insurance in the County.The Florida Public Hurricane Model currently contains a model that is unique to Monroe County.
