Understanding the Coastal Barrier Resources System (CBRS)
The Coastal Barrier Resources System (CBRS) is a collection of specific geographic areas along the Atlantic, Gulf of Mexico, Great Lakes, U.S. Virgin Islands, and Puerto Rico coasts. These areas consist of undeveloped coastal barriers that are protected by federal law. The primary objective of the legislation governing these areas is to minimize the loss of human life, reduce wasteful federal expenditures, and protect the natural resources of these sensitive coastal environments.
For insurance professionals, the most critical aspect of the CBRS is the restriction it places on federal financial assistance. In these designated zones, the federal government does not provide financial support for development, which includes the provision of federal flood insurance through the National Flood Insurance Program (NFIP). Understanding how these zones impact eligibility is vital for anyone preparing for the complete Flood exam guide.
CBRS Impact and Scope
NFIP Restrictions and Eligibility
The central rule regarding the CBRS is that most new construction or substantially improved structures within these areas are ineligible for NFIP flood insurance. This restriction serves as a deterrent to development in high-risk, environmentally sensitive areas. If a property is located within a designated CBRS unit, the NFIP cannot issue a policy unless the structure meets very specific, narrow exceptions.
When reviewing applications, agents must determine if the building was constructed or substantially improved after the date the area was designated as part of the CBRS. If the construction occurred after the designation date, federal flood insurance is prohibited. This is a common point of confusion on the exam; remember that the prohibition applies specifically to federal insurance, not necessarily private market options.
- System Units: These are the areas most strictly regulated, where almost all federal subsidies are prohibited.
- Otherwise Protected Areas (OPAs): These are usually lands held for conservation or recreation, such as national parks or wildlife refuges. While they are part of the CBRS, the restrictions on NFIP insurance apply only to new construction within these boundaries.
System Units vs. Otherwise Protected Areas (OPAs)
| Feature | System Units | Otherwise Protected Areas (OPAs) |
|---|---|---|
| Primary Purpose | Protect undeveloped barriers | Conservation/Recreation |
| NFIP Eligibility | Prohibited for new construction | Prohibited for new construction |
| Federal Subsidies | All federal subsidies prohibited | Only NFIP insurance prohibited |
| Mapping Symbol | Typically identified by Unit ID | Typically identified by 'P' suffix |
Substantial Improvements and Damage
A critical nuance in CBRS regulations involves substantial improvements and substantial damage. If a structure was built before the CBRS designation and currently holds an NFIP policy, it may continue to be covered. However, if that structure undergoes a substantial improvement—meaning the cost of the improvement equals or exceeds 50 percent of the market value of the building—the building loses its eligibility for federal flood insurance.
Similarly, if a building is substantially damaged (damage where the cost of restoration equals or exceeds 50 percent of the market value) and the owner wishes to rebuild, the resulting structure is treated as new construction. Because it is located within a CBRS unit, it would no longer be eligible for an NFIP policy. Agents must warn clients in these areas that a single major storm could effectively end their access to federal flood insurance.
Exam Tip: Mandatory Purchase Requirement
Determining CBRS Status
To determine if a property is in a CBRS area, insurance professionals must consult the Flood Insurance Rate Map (FIRM). CBRS boundaries are clearly marked on these maps. It is the responsibility of the agent to verify the location of the property relative to these boundaries before submitting an application to the NFIP.
If a property is located within a CBRS unit, the agent must provide documentation proving that the building was constructed before the designation date to obtain coverage. This documentation typically includes a CBRS Determination from a local official or a valid building permit that predates the designation.
