Building on 100 Years of Planning Advocacy

The Committee of 100 on the Federal City is celebrating its centennial in 2023.  In 1923, a group of distinguished citizens founded The Committee of 100 on the Federal City to sustain and safeguard the fundamental values of the L’Enfant and McMillan Plans that give the nation’s capital much of its distinction, beauty and rich community character. As independent citizen advocates for sound planning, we are active city-wide in land use planning, zoning, transportation, historic preservation and parks and open space conservation.
