What Is the Coastal Barrier Resources Act (CBRA)?

The Coastal Barrier Resources Act (CBRA) is a U.S. federal law enacted in 1982 to minimize the loss of human life, reduce wasteful federal spending, and protect coastal environments by restricting federal financial assistance for development in designated coastal barrier areas. The CBRA established the Coastal Barrier Resources System (CBRS), a network of undeveloped coastal barriers along the Atlantic Ocean, Gulf of Mexico, Great Lakes, and certain other coastal areas. The law discourages development in these areas by making them ineligible for federal subsidies, such as flood insurance through the National Flood Insurance Program (NFIP), infrastructure funding, and disaster relief.

Background and Purpose

Before the CBRA, coastal barrier islands and adjacent areas were frequently developed with federal support, leading to environmental degradation and high financial costs due to storm damage. Coastal barriers, which include sandbars, barrier islands, and other coastal landforms, serve as natural buffers against storm surges, high waves, and erosion. Their destruction for development not only led to increased disaster risks but also created a financial burden for taxpayers, as the federal government was often responsible for disaster recovery, infrastructure repair, and flood insurance payouts.

The CBRA sought to address these issues by removing federal incentives for development, effectively allowing natural market forces to determine land use. Without federal backing, the cost of building in CBRS-designated areas increased, making it less attractive to developers and reducing the likelihood of large-scale construction in sensitive coastal regions.

Key Provisions

The CBRA primarily works by designating areas within the Coastal Barrier Resources System (CBRS), where certain federal financial assistance is prohibited. This includes:

• Flood Insurance Restrictions: Properties in the CBRS are ineligible for coverage under the National Flood Insurance Program (NFIP), making it more expensive and difficult for property owners to insure their buildings against flood damage.
• Infrastructure Funding Limits: The federal government does not provide funding for new infrastructure, such as roads, wastewater treatment plants, or electrical grids, in CBRS areas.
• Disaster Relief Exclusions: Federal disaster assistance programs generally do not cover CBRS properties, meaning that homeowners and businesses must rely on private insurance or state and local resources in the event of storm damage.
• Building and Development Deterrence: By restricting federal assistance, the CBRA aims to prevent unsustainable development in fragile coastal ecosystems, allowing natural processes to continue with minimal human interference.

These provisions do not outright prohibit private development. Property owners can still build in CBRS areas, but they must do so without federal financial assistance, making development significantly more costly and less viable.

Coastal Barrier Resources System (CBRS)

The CBRS is a mapped collection of coastal barrier areas designated by the CBRA. These areas are regularly reviewed and updated by the U.S. Fish and Wildlife Service (USFWS), which oversees the program. The CBRS includes "System Units" and "Otherwise Protected Areas (OPAs)":

• System Units: These are primarily undeveloped barrier islands and coastal lands that receive the full set of CBRA protections, meaning that federal funding, including NFIP coverage, is restricted.
• Otherwise Protected Areas (OPAs): These are areas within the CBRS that are already under conservation management (e.g., wildlife refuges, state parks). They remain ineligible for federal flood insurance, but other types of federal funding may still be available.

CBRS maps are used to determine which properties are within these designated areas, and they play a critical role in guiding land use planning and development decisions.

Impacts and Effectiveness

The CBRA has played a significant role in reducing government expenditures on risky coastal development. By shifting the financial burden to developers and property owners, it has discouraged high-risk construction and helped preserve natural coastal barriers. The law has also supported conservation efforts, as many CBRS areas remain undeveloped and serve as habitats for wildlife, including endangered species.

However, the CBRA has also faced challenges. Some property owners and developers have sought exceptions to the law, arguing that their land should be removed from the CBRS to qualify for federal assistance. Political pressure has occasionally led to legislative efforts to modify CBRS boundaries, though these changes are generally subject to scientific review and public input.

Another challenge is that some developments in CBRS areas still occur, particularly when private funding is available. In these cases, property owners bear higher risks, as they cannot rely on federal flood insurance or disaster relief. This has led to debates over whether additional regulations are needed to further discourage development in sensitive coastal zones.

Future Considerations

As climate change increases the frequency and intensity of hurricanes, storm surges, and sea-level rise, the CBRA's role in mitigating risk and protecting coastal environments is becoming even more relevant. The law continues to serve as a model for sustainable coastal management by reducing incentives for risky development and encouraging conservation.

Advancements in mapping technology have allowed for more precise identification of CBRS areas, ensuring that the CBRA remains effective in its intended goals. Policymakers continue to evaluate whether additional measures, such as expanding CBRS designations or strengthening enforcement, are necessary to address growing coastal risks.

The Bottom Line

The Coastal Barrier Resources Act is a landmark environmental and economic policy designed to reduce federal spending on high-risk coastal development while preserving natural coastal barriers. By restricting federal subsidies, including flood insurance and infrastructure funding, the CBRA discourages unsustainable development in sensitive coastal regions. Over the years, it has helped protect critical habitats, reduce taxpayer burdens, and promote more responsible land use in vulnerable coastal areas. As climate change intensifies coastal hazards, the CBRA remains an important tool in managing coastal resilience and environmental conservation.
