Why so many suburbs look the same

It was all part of the plan.

It was all part of the plan.

If you’ve visited a suburb, you’ve probably noticed a similar look: same curving streets, same culs-de-sac. It’s not an accident. In fact, this appearance of the suburbs was part of the Federal Housing Administration’s plan. The above video tells the full story.

In the 1930s, the Federal Housing Administration (FHA) was the financial engine behind most home development. To ensure their investments were safe ones, they strongly recommended that builders and developers comply with the ideals they set. Those regulations aligned closely with the values of the time, including segregation and a burgeoning car culture.

These rules encouraged suburbs with winding streets and culs-de-sac — aesthetically pleasing designs that led to sprawl and made a car a necessity. Even though the enforcement mechanisms have changed over time, we still live in a culture shaped by the FHA’s ideal suburban design.

Watch the video above to see how it happened.
