Summary: The Corps is proposing to repeal and replace part 203. In this selected alternative, the Corps proposes to incorporate and integrate the current state of the practice of flood risk management principles and concepts through the provision of agency policy codified in a federal rule. The intended benefit is to encourage broader community flood risk management activities by non-Federal project sponsors specific to the flood risk management projects they operate and maintain and in coordination with the applicable communities. This rule alternative also consolidates recent Public Law 84-99 amendments into one comprehensive rule, ensuring the public has a clear understanding of the responsibilities and requirements.

Need for Revision

This rule includes a proposed change in the focus of the Rehabilitation Program. The eligibility of a levee system for consideration for rehabilitation assistance after a flood was once based only on inspections conducted by the Corps. More recently, the Public Law 84-99 program has been transitioning to risk-informed eligibility determinations for projects, which are based on an evaluation of the non-Federal sponsor's overall risk management activities, including information developed through inspections. Additional changes are also proposed to effectively implement recent amendments to Public Law 84-99.

Since the last revision in 2003, significant disasters, including Hurricane Katrina (2005), Hurricane Sandy (2012), flooding on the Mississippi and Missouri Rivers (2008, 2011, and 2013), and Hurricanes Harvey, Irma, and Maria (2017) have provided a more detailed understanding of the nature and severity of the risks associated with coastal storms and floods. These significant events provided information regarding project performance and the effects of climate change that the Corps has considered when formulating this rule update.

Additionally, the maturation of risk-informed decision-making approaches and technological advancements from a purely standards-based perspective has influenced the outlook on how Public Law 84-99 activities should be implemented, with a shift towards better alignment with the Corps Levee Safety and National Flood Risk Management Programs. Risk-informed decision making uses an iterative process to reduce risk over time by identifying the areas of acceptable risk, monitoring the acceptable risk, and then devoting resources to manage the sources of unacceptable risk in priority order. The process begins by capturing activities and efforts within three overarching categories: risk assessment, risk management, and risk communications. Through this process, the Corps and non-Federal sponsors assess the flood risk to property, infrastructure, public safety, and the environment; and seek to reduce that risk in stages by addressing the highest priority flood risk management deficiencies first, and by working with elected officials and other risk managers to identify other priority areas for investment.
