Title 33 › Chapter CHAPTER 46— - NATIONAL LEVEE SAFETY PROGRAM › § 3303
The Secretary must create and keep a national levee database within 1 year of December 16, 2016. The database must list where federal levees are (including GIS info) and include updates from states, tribes, regional districts, federal agencies, and others. It must note the general condition of each levee and estimate how many buildings and people would be hurt if a levee failed or was overtopped. The Secretary must share all database information with federal, state, regional, tribal, and local governments, and must publish levee locations and any other parts of the database the Secretary chooses for the public. The Secretary must inventory and inspect levees: federally owned and run levees at federal cost; federally built but not federally run levees at the project’s original cost share; and non‑federal levees that ask for inspection if their owners are in the emergency response program, with the federal share at 65 percent. The Secretary must do a one-time review of all levees in the database, decide if some need a deeper inspection using the levee safety action classification criteria, and allow state, regional, or tribal officials to join reviews or get information. The review does not make the federal government responsible for building, operating, or maintaining a levee. For each levee inspected or reviewed, the Secretary must identify any engineering or maintenance problems, describe fixes, and provide cost estimates if a non‑federal owner asks. The Secretary must consult and let non‑federal interests comment during these steps.
