The major comprehensive plans for the National Capital Region are the L'Enfant Plan and the McMillan Plan.

In the following century, the Versailles design influenced Pierre Charles L'Enfant's master plan for Washington, D.C. See, L'Enfant Plan.

The L'Enfant Plan featured broad streets and avenues radiating out from rectangles, providing room for open space and landscaping.

The L'Enfant Plan proposed a city of beauty.

The original street layout in the new City of Washington was designed by Pierre (Peter) Charles L'Enfant (see L'Enfant Plan).

The original L'Enfant Plan setting out the streets of the District of Columbia still existed in the Federal Triangle area.

The area of Southwestern Washington, D.C., where the Forrestal Building is located was originally laid out in a grid pattern as specified by the L'Enfant Plan of 1791.

The committee believes its goals can best be achieved by adhering to the 1791 L'Enfant Plan and the 1902 McMillan Plan.

The Committee's goal was to support the 1791 L'Enfant Plan and the 1902 McMillan Plan for the development of the capital.

Foggy Bottom, along with the rest of Washington D.C, was designed using the L'Enfant Plan, which created squares of housing with open space left in the middle.
