FEMA's National Flood Insurance Program was designed to save homeowners from disaster — instead it became a $20 billion debt-ridden mechanism that subsidizes the wrong development in the wrong places while blocking the right kind everywhere else. The flood maps that determine what you can build, where you can insure it, and whether your mortgage gets approved are often decades out of date, methodologically contested, and quietly negotiated between local governments and federal bureaucrats in ways that have nothing to do with actual water. This week: the single least-glamorous program in Washington that shapes more of the American built environment than any zoning board or city council ever has.
