United States v. Sponenbarger

Background

The case involves a Mississippi River landowner in Desha County, Arkansas who sued the United States under the Tucker Act. She said the Mississippi Flood Control Act of 1928 and a planned Boeuf floodway with a nearby "fuse plug" would intentionally divert floodwaters onto her farm and amount to a taking that required compensation. The District Court found for the Government, concluding no new flooding had been caused and that the Government’s program actually reduced flood risk to her land. The Court of Appeals reversed, and the Supreme Court took the case because of the legislation’s importance.

Reasoning

The Court focused on whether the federal program and river work created a compensable taking. It relied on factual findings that no work was done in the proposed Boeuf floodway, the fuse plug was never established and the floodway was abandoned, and that river improvements had generally lowered river crests and improved protection. The Court also noted the area had long been a natural floodway and that Congress required surveys and left many implementation details to administrators. Because the Government did not increase the existing flood hazard and the program conferred net benefits to the land, the Court held there was no taking and reversed the Court of Appeals.

Real world impact

The decision means federal flood-control projects are not automatically a taking requiring payment unless the Government’s actions increase flood risk or directly damage property. Local levee rights remain available and Congress’s broad program may be implemented without compensating every owner who faces a possibility of future overflow. The Court left open statutory questions about recovery in other factual settings but disposed of this landowner’s claim.
