Public infrastructure projects funded by federal emergency funds are facing stricter flood-risk standards in order to combat the increasing impacts of climate change. The Biden administration announced the implementation of new regulations that require buildings and other infrastructure built with Federal Emergency Management Agency (FEMA) funds to be elevated higher above local flood levels or relocated to safer areas. These changes are crucial to mitigate the risks posed by rising sea levels and extreme weather events.
The worsening effects of climate change, such as sea-level rise and intense storms, have significantly increased flood risk across the country. According to FEMA administrator Deanne Criswell, climate change has exacerbated the frequency and severity of flooding events, making it imperative to adopt measures that address future climate risks. The Federal Flood Risk Management Standard aims to incorporate the best available scientific data to enhance the resilience of projects and communities in the face of heightened flood conditions.
While the implementation of stricter flood-risk standards may lead to higher project costs initially, officials argue that the long-term savings and benefits will outweigh the expenses. FEMA’s investment in elevating new building designs by two feet, on average, adds approximately 1.91% to the project cost. This upfront cost is justified by the savings achieved over time, as projects built to withstand future flood risks will require less maintenance and repair in the future.
The new standard introduced by FEMA signals a shift towards forward-looking planning in infrastructure development. Rather than solely considering current flood risks, officials are now required to account for future flood threats when designing and rebuilding after disasters. This proactive approach aims to increase resilience and reduce the impact of climate change-induced disasters on lives, property, and critical infrastructure.
In addition to elevating structures to mitigate flood risks, the new standard emphasizes the importance of using natural features and nature-based approaches in floodplain and wetland projects. By preserving the beneficial functions of these ecosystems, officials can enhance the resilience of communities and reduce the need for costly interventions in the event of disasters. This holistic approach to flood-risk management aligns with the broader goal of sustainability and environmental conservation.
Despite the urgency of implementing stricter flood-risk standards, many local governments face challenges in securing the necessary funding for infrastructure projects. A survey conducted by the National League of Cities revealed that only 24% of municipalities are currently using climate data in their capital planning processes. Addressing funding barriers and increasing access to resources will be vital in enabling communities to meet the new flood-risk standards and enhance their resilience to climate change impacts.
The adoption of stricter flood-risk standards in public infrastructure projects represents a crucial step towards addressing the growing challenges posed by climate change. By incorporating scientific data, investing in resilient designs, and integrating nature-based approaches, communities can better prepare for and mitigate the impact of future flood events. It is essential that stakeholders at all levels work together to prioritize climate resilience and safeguard the safety and security of the American people and our infrastructure.
