Levee Safety Action Classification
A key lesson learned from Hurricane Katrina is the importance of risk communication so that local officials, stakeholders, and the public have the best information available in order to make informed risk-based decisions. The Levee Safety Action Classification (LSAC) is one of the many tools we use to better inform our stakeholders and residents of the residual risk in their communities.
The LSAC is neither a levee rating or grade, it is a classification system designed to take into account the probability of the levees being loaded (Hazard), existing condition of the levee, the current and future maintenance of the levee (Performance), and the Consequences if a levee were to fail or be overwhelmed.
A levee that reduces risk for a dense population will receive a different classification from an equally constructed levee with a smaller population because the consequences associated with failure is greater.
Levee Safety Program
Following Hurricane Katrina in 2006, the U.S. Army Corps of Engineers created its Levee Safety Program to assess the integrity and viability of levees and to make sure that levee systems do not present unacceptable risks to the public, property, and the environment. The basic objectives of the Levee Safety Program are to:
- Develop balanced and informed assessments of levees within the program.
- Evaluate, prioritize and justify levee safety decisions.
- Make recommendations to improve public safety associated with levee systems.
The National Levee Database is a component of the Levee Safety Program which inventories all levees in the program and aims to continually improve inspection procedures. The Levee Safety Action Classification (LSAC) falls under the Database. (Additional information about the National Levee Database can be found on the back of this brochure.)
