FLOOD INSURANCE BASICS

For a Charleston resident, real estate flood insurance is considered a common reality. While the National Flood Insurance Program - NFIP is a typical part of most homes sales, it is often misunderstood, and for good reason. With terms like "FIRM" & "Zones" and documents such as "Elevation Certificates" & "Maps" only qualified agents are capable explaining and providing flood insurance.

FLOOD MAPS

Understanding & Changes

Flood Insurance Rate Maps (FIRMS) are created and maintained to display degrees of risk for communities. These existing flood map zones help determine the cost of flood insurance. Flood risk and cost can, and does, change over time. FEMA is currently updating flood hazard maps across the nation. These new flood maps, also, known as Digital Flood Insurance Rate Maps (DFIRMs), provide an official depiction for each community and show flood risk at a property-by-property level.

As new maps are published your risk may change along with your flood insurance requirements! If you've been included into a high-risk area, you will likely be required to purchase flood insurance, and it is possible that when new maps are released your property may no longer meet federal, state or local standards and will become regulated by a new set of flood related construction rules. Visit FEMA.gov to see if a new flood hazard map for your community is available.

COST

Flood Insurance Rates

In the greater Charlestons Areas (X Zones) expect coverage to cost between .75% and 1% of home replacement cost (not property value). A premium for a $200k home might be $1,000 to $2,000 a year. On Charleston’s Barrier Islands (A & V Zones) coverage could cost between 1% and 1 ½%. A premium for a $200k home might be $2,000 to $3,000 a year. However, a 1 million dollar newer home with hurricane windows might only be $4,500 to $5,500 a year with Wind & Hail coverage, but this same home with some slight differences could cost $10,000 to $12,000 a year. However, each risk varies so much there is not a standard percentage…there is just no standard quote anymore. The only way to know the cost (full risk rate) is having a new or current elevation certificate (typically cost $300-$500) then finding and speaking with an Insurance Agent.

If you have any additional questions or need an insurance quote on any real estate contact us. We would be glad to refer you to a great a local qualified Insurance Agent who can accurately quote any home you’re interested in. Here is a sampling of policy premiums for different zones.

DEFINITIONS:

There many words, phrases, and acronyms used was talking and writing about Flood. Below we have complied a short list of the most common one's. Understanding these, and the relationships to each other will make navigating a Flood conversation much easier.

Flood Zone Describes that land area in terms of its risk of flooding.
Special Flood Hazard Areas (SFHA) Flood zones that have the greatest risk of flooding. During a 30-year mortgage, there is a 26% chance of flooding in these areas and only a 4% chance of fire in the same period. Designations start with the letters “A” (Riverine/Inland Group) or “V” (Coastal Group) - indicated by tidal floods with velocity.
Non-Special Flood Hazard Areas (NSFHA) Low to moderate risk flood zones. Historically, 30% of all claims occur in these areas (A Preferred Risk Policy may be available). Designations start with the letters B, C, and X
Base Flood Elevation (BFE) Level at which there is a 1% chance of flooding in any given year.
Elevation Certificate (EC) Tool that documents your building’s elevation.
Flood Insurance Rate Map (FIRM): A map issued by FEMA showing flood risk, BFEs, and risk premium zones.
NFIP National Flood Insurance Program.
Non-Primary Residence If the building will be lived in for less than 80 percent of the policy year, it is considered to be a non-primary residence.
Pre-FIRM Buildings constructed BEFORE the community’s first Flood Insurance Rate Map became effective and has not been substantially damaged or improved.
Post-FIRM A building constructed or substantially improved on or AFTER December 31, 1974, or on or after the date of the initial FIRM for your community. Coastal Barrier Resource System: South Carolina;

Charleston County- 4/27/71
Berkeley County- 9/30/1983
Dorchester County- 1/6/1982

Zone A Areas of moderate to high hazard subject to flooding from severe storm activity or local drainage problems.. Mandatory flood insurance purchase requirements apply.
Zones B, C, and X Areas of moderate or minimal hazard subject to flooding from severe storm activity or local drainage problems. Flood insurance purchase is not required.
Zone V An area that is inundated by tidal floods with velocity (coastal high hazard area). Mandatory flood insurance purchase requirements apply.

THE ESSENTIALS

In what community is the property located?
Community Status - Regular or Emergency Program?
In what zone is the building/home located?
What is the building’s Date of Construction (DOC)?
Is the building Pre-FIRM or Post-FIRM?
Is an Elevation Certificate required?
What is the occupancy of the building?
How many floors in building (including basement/enclosure)?
Does the building have a basement/enclosure?
What is the replacement cost of the building?
How much insurance is required?
What deductible has the client requested?

PRE-FIRM & POST-FIRM

FIRM Determination: Compare Initial FIRM Date with Date of Construction (DOC) or Substantial Improvement Date (Initial FIRM is when the Community first enters the Regular Program).

• Pre-FIRM: If DOC is on or before 12-31-1974 or before initial FIRM Date
• Post-FIRM: If DOC is after 12-31-1974 or on or after initial FIRM Date, whichever is later.

FLOOD ZONES

Special Flood Hazard Areas (SFHA)

SFHAs are the flood zones that have the greatest risk of flooding. They are darkly shaded areas on the maps. During a 30-year mortgage, there is a 26% chance of flooding in these areas and only a 4% chance of fire in the same period. SFHA Zones designations start with the letters;

“A” (Riverine/Inland Group) - moderate risk for flooding or drainage problems from severe storms.

“V” (Coastal Group) - high risk indicated by tidal floods with velocity.
The Base Flood Elevation (BFE) and Base Flood Depth (BFD) is the level at which there is a 1% chance of flooding in any given year.

SFHA Zones

A or V    BFEs not provided.
A1-A30    BFEs are provided.
AE    (AE replaces A1-A30 on new FIRMs).
V1-V30    BFEs provided.
VE    (VE replaces V1-V30 on new FIRMs).
AH    Shallow water depths (ponding, 1-3 feet).
AO    Shallow water paths (sheet flow, 1-3 feet). BFDs (Base Flood Depths) may be provided.
A99    A protective system such as dikes, dams and levees. No BFEs are provided.
AR    Area that results from decertification of a previous flood protection system.

Non-Special Flood Hazard Areas (NSFHA)

NSFHA Zone designations start with the letters;
"B", "C", and "X" - low to moderate risk flood zones.
On the FIRM, they are unshaded or lightly shaded. Historically, 30% of all claims occur in these areas (A Preferred Risk Policy may be available).

NSFHA Zones
B, C, & X Are low to moderate-risk flood zones.

ELEVATION CERTIFICATES

Certificate NOT Required

All Pre-FIRM Zones
Post-FIRM Zones B, C, X*, A99, D & AR
* X Zones may be shaded or unshaded. Shaded X Zone replaces the B Zone and Unshaded X Zone replaces, the C Zone on new FIRMs.

Certificate IS Required

All Pre-FIRM Zones
A1-A30, AE, AH, V1-30, VE
A1-A30, AE, AH, V1-30, VE
A*
A0**
*Unless BFE information is available from the community, use the measured difference between the highest adjacent grade and the top of the bottom (lowest) floor. An elevation Certificate not required but may result in better rates.

** AO Property owner, owner’s representative or building official can complete. Use 2ft if no BFDs are shown on the Map.

Where to Obtain an Elevation Certificate

To find out if a certificate already exists, check with the community department that maintains local maps or the local permit office. To have a certificate completed, contact a licensed land surveyor, registered local law to certify elevation information, except as noted above in Zone AO or A (without BFE).
