​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 of 100 on the Federal City’s  actions and priorities throughout its history to benefit the residents of Washington, DC.

As stewards of the nation’s capital, the Committee of 100 on the Federal City continues its long-standing advocacy to protect Washington, D.C.’s historic planning principles and public green spaces. In response to recent federal actions bypassing crucial public oversight, historic preservation laws, and congressional mandates, the Committee—alongside a coalition of national preservation and planning organizations—has taken legal action to challenge three major projects initiated by the Trump administration: sweeping modifications to the John F. Kennedy Center for the Performing Arts, the construction of a massive new White House Ballroom, and the proposed “National Garden of American Heroes” in West Potomac Park.
