The Committee of 100 on the Federal City

​Since its founding in 1923, the Committee of 100 on the Federal City has championed the fundamental values of the L’Enfant and McMillan Plans to sustain the distinction, beauty, and varied neighborhoods of the nation’s capital. As independent advocates for sound planning, we are active city-wide in land-use, housing, transportation, historic preservation, and the environment.

The Committee’s vision of a beautiful and livable city for all has guided the Committee’s actions and priorities throughout its history.
