Levee Safety Program


Levee systems are part of our nation’s landscape and important to communities because of the benefits they provide. For example, more than 13 million people live or work behind levees in the U.S. Army Corps of Engineers’ (USACE) Levee Safety Program. And, public and private property worth more than one trillion dollars are behind these levees.

Through, the Levee Safety Program, USACE partners with levee sponsors to manage more than 1,600 levees across the U.S. that help reduce flood risk to people, businesses, critical infrastructure and the environment.

USACE and levee sponsors work together to understand the benefits and risks associated with levees, build awareness among the public, fulfill daily responsibilities on levees, and take actions to manage the future performance of the levee.

The USACE Levee Safety Program serves as an organizing framework to improve consistency and coordination in how levee-related activities are implemented across USACE. Key program activities include levee inspections, risk assessments, and sharing levee information. These activities are intended to support defendable levee decisions and more aware communities and members of the public.

Levee Safety Program Guidance

USACE welcomes feedback on how things are going by emailing EC218@usace.army.mil.

USACE recently published Engineer Circular 1165-2-218: U.S. Army Corps of Engineers Levee Safety Program, which informs how USACE implements its Levee Safety Program. The Engineer Circular will expire two years after publication. USACE will work with its partners to implement and improve this guidance during this two-year period and issue more permanent agency guidance based on input and lessons learned.

Related Initiatives: National Levee Safety Program Initiative

Congress has authorized development of a National Levee Safety Program, a new initiative being co-led by USACE and the Federal Emergency Management Agency (FEMA). This program is focused on developing tools and resources to support all stakeholders across the Nation in promoting consistent levee management, reducing flooding impacts, and increasing community resilience in areas behind levees. Tools and resources include a consistent set of national best practices, a database of the most complete data record for all levees, and various types of assistance (e.g., templates and training). More information on the National Levee Safety Program and upcoming opportunities to offer input is available by visiting https://www.leveesafety.org.

National Levee Database – Redesigned Site Available

The National Levee Database (NLD), available at https://nld.sec.usace.army.mil, captures all known levees in the U.S. It is designed to provide a variety of users the ability to search for specific data about levees and serves as a national resource to support awareness and actions to address flooding.

USACE is updating the site based on feedback received during a series of stakeholder sessions hosted in January – March 2022 to inform development of the National Levee Safety Program.

The redesigned NLD will be available in February 2024 and includes a few key changes:

  • A new website address – nld.sec.usace.army.mil. The previous website (levees.sec.usace.army.mil) will temporarily redirect to the new address.
  • A new landing page with an updated look and feel, including quick access to key tools, levee statistics, and basic information.
  • A streamlined summary page for each levee to include the most applicable information for communities behind levees.
  • New procedures to obtain a user account for more advanced users.
