Levees / Rehabilitation programme

Most levees are outside the federal repair programme.

A levee has to be enrolled in the USACE Rehabilitation and Inspection Program before a flood to be eligible for repair assistance under Public Law 84-99 afterwards. On the federal register, 5,022 of 7,626 systems are recorded as not enrolled.

What not enrolled actually means

It is a statement about programme status, not about the condition of the embankment. A system outside the programme may be perfectly well maintained. What it does not have is the federal backstop: only systems that were Active in the programme before a flood event can receive PL 84-99 rehabilitation assistance. A sponsor discovering this after a flood has discovered it too late.
