What Is CBRA Flood Insurance and Who Writes It?

CBRA flood insurance refers to flood coverage for properties located in zones designated under the Coastal Barrier Resources Act, federally protected coastal areas where the National Flood Insurance Program (NFIP) is prohibited from writing new policies. Because homeowners and businesses in these zones can't rely on the NFIP, CBRA flood coverage is written by private flood insurers and MGAs instead, making it one of the clearest cases where private flood insurance isn't just an alternative to the NFIP — it's the only option.

This article explains what CBRA zones are, why the NFIP can't write there, and what independent agents need to know when a client's property falls inside one.

What Is the Coastal Barrier Resources Act

The Coastal Barrier Resources Act (CBRA) is a federal law designed to limit development and reduce federal spending in ecologically sensitive coastal barrier areas, such as barrier islands, dunes, and other undeveloped coastal land. As part of that law, properties located within designated CBRA zones are not eligible for new NFIP flood insurance policies. The designation is tied to specific mapped zones maintained by the U.S. Fish and Wildlife Service, not to a general description of "coastal" property — a home can be near the water and fall entirely outside a CBRA zone, or be well within one.

Why the NFIP Can't Write Coverage in CBRA Zones

The NFIP is a federal program, and CBRA is a federal law that directly restricts what the NFIP can insure. Congress designed CBRA to discourage new development in these protected coastal areas by removing federal incentives, including flood insurance backstops, that might otherwise support building there. The result is straightforward for agents: if a property sits inside a CBRA zone, an NFIP policy is not an option, full stop, regardless of when the structure was built or how the property is used.

This is different from other NFIP restrictions, such as coverage limits or waiting periods, which apply broadly but still leave an NFIP policy available. A CBRA designation removes the NFIP from the table entirely for that property.

How Private Flood Insurance Fills the CBRA Gap

Because the NFIP cannot write in CBRA zones, any flood coverage for a property located there has to come from the private market. This is one of the primary reasons private flood insurance exists as a distinct product category, separate from being simply a cheaper or faster alternative to NFIP coverage.

Private flood MGAs that write CBRA coverage typically also handle standard residential and commercial flood business, since many of their appointed agents have clients both inside and outside CBRA zones. Sterling Flood, a private flood MGA founded in 2008 and based in Madison, Mississippi, is one example of a program that writes CBRA flood coverage alongside residential, commercial, and excess flood coverage, across 47 states. Sterling Flood is not affiliated with Sterling Insurance Company of Cobleskill, New York, a separate company with a similar name.

How Agents Identify a CBRA Property

Determining whether a specific property sits inside a CBRA zone requires checking official CBRA maps, which are maintained at the federal level and are distinct from standard FEMA flood zone maps. A property can be in a high-risk Special Flood Hazard Area and also be in a CBRA zone, or be in a CBRA zone with a lower base flood risk designation — the two classifications are separate questions. Agents who aren't sure whether a client's address falls inside a CBRA zone should confirm with the specific flood program they're quoting with.

What This Means for Coastal Clients

For a client who owns property in a CBRA zone, flood insurance isn't a nice-to-have add-on to discuss at renewal — it's often the only type of flood coverage available to them at all, and it needs to be addressed at the time of purchase or refinance. Federally regulated lenders still require flood insurance on properties in Special Flood Hazard Areas regardless of CBRA status, and lenders must accept private flood policies that meet the regulatory definition of private flood insurance. That means a CBRA-zone client who needs flood coverage to close a loan is depending entirely on the private market to get that transaction done.

Common Mistakes

• Assuming a coastal property is automatically in a CBRA zone, or assuming it isn't, without checking the actual designated zone maps.
• Telling a client flood insurance "isn't available" for their property when a CBRA designation only rules out the NFIP, not private flood coverage.
• Waiting until a loan closing deadline to discover a property is in a CBRA zone and scrambling to find a private market that writes there.

Frequently Asked Questions

What does CBRA stand for in flood insurance?

CBRA stands for the Coastal Barrier Resources Act, a federal law that restricts the NFIP from writing new flood insurance policies in designated coastal barrier zones.

Can a CBRA-zone property get flood insurance at all?

Yes, through the private flood insurance market. The NFIP cannot write new policies in CBRA zones, but private flood MGAs and carriers can.

How do I know if my client's property is in a CBRA zone?

CBRA zones are defined by official federal maps separate from standard FEMA flood zone maps. Agents should check the property against CBRA zone maps directly or confirm status through the private flood program they're quoting with.

Does Sterling Flood write coverage in CBRA zones?

Yes. Sterling Flood writes CBRA flood coverage alongside residential, commercial, and excess flood coverage across 47 states.

Placing CBRA Coverage for a Client

Independent agents with a client in a CBRA zone need a private market that can write there, since the NFIP isn't an option. Agents who want to add CBRA flood coverage to their appointments can get set up as a producer with a private flood MGA like Sterling Flood and begin quoting CBRA, residential, commercial, and excess flood coverage at sterlingflood.com.
