[Note via NPS – “The plan of the city of Washington was designed in 1791 by Pierre L’Enfant, and mapped the following year; a design which remains largely in place. For nearly a century, the realization of physical changes to the original plan were gradual until the second important benchmark in the development of Washington’s urban plan: the McMillan Commission and its 1901-02 recommendations.”]
