It’s an article, “The Creeping Storm,” from the June 2003 Civil Engineering magazine. Money quote:

Today New Orleans rests within a bowl formed by 16 ft (4.9 m) tall levees,
locks, floodgates, and seawalls, the edge of the bowl extending for hundreds
of miles. It is bisected from west to east by the Mississippi River, which is
also contained within massive engineered embankments. Water flows through and
all around the city while its residents go about their daily routines. A system
of levees forming a ring around the northern half of the city to protect it
from surging waters in Lake Pontchartrain is set to be completed within the
next decade. Construction of a similar system around the southern half of the
city will probably take several years longer than that.

Those who say Bush’s reduction of the budget for a flood-control study last year caused the calamity in New Orleans are either misinformed or intentionally lying.
