D.C. Mun. Regs. tit. 10, r. 10-A1010
The Plan of the City of Washington drawn by Pierre L'Enfant in 1791 has served as an enduring symbol and armature for growth of the national capital. More than two centuries of public and private building construction have given shape to the plan. Great civic works and public art have embellished it. After its first hundred years, the plan was reinvigorated according to City Beautiful principles in the McMillan Plan of 1901. Regulated building heights and mandated design review by agencies like the Commission of Fine Arts further supported its enhancement and embellishment. 1010.1
The design principles of the Plan informed the platting of streets and parks in new neighborhoods as the city expanded beyond its initial boundaries. Despite alterations and intrusions, it still serves as the basis for the Legacy Plan adopted in 1997 by the National Capital Planning Commission for the 21st Century. 1010.2
Policy HP-2.3.1: The Plan of the City of Washington
Preserve the defining features of the L'Enfant and McMillan plans for Washington. Work jointly with federal agencies to maintain the public squares, circles, and major reservations as landscaped open spaces that provide a means to experience the legacy of the city plan. Preserve the historic pattern of streets and associated minor reservations, and protect these historic rights-of-way from incompatible incursions and intrusions. 1010.3
Policy HP-2.3.2: Historic Image of the City
Protect and enhance the views and vistas, both natural and designed, which are an integral part of Washington's historic image. Preserve the historic skyline formed by the region's natural features and topography and its historically significant buildings and monuments from intrusions such as communication antennas and water towers. Preserve the horizontal character of the national capital through enforcement of the 1910 Height of Buildings Act. 1010.4
Policy HP-2.3.3: Spatial Character of L'Enfant Plan Streets
Protect the generous open space and reciprocal views of the L'Enfant Plan streets, avenues, and reservations. Protect the integrity and form of the L'Enfant system of streets and reservations from inappropriate new buildings and physical incursions. Support public and private efforts to provide and maintain street trees to help frame axial views and reinforce the city's historic landscape character. 1010.5
Policy HP-2.3.4: Public Space Design in the L'Enfant Plan
Reinforce the historic importance and continuity of the streets as public thoroughfares through sensitive design of sidewalks and roadways. Avoid inappropriate traffic channelization, obtrusive signage and security features, and other physical intrusions that obscure the character of the historic street network. Work jointly with federal agencies to preserve the historic statuary and other civic embellishments of the L'Enfant Plan parks, and where appropriate extend this tradition with new civic art and landscape enhancements of the public reservations. 1010.6
Policy HP-2.3.5: Enhancing Washington's Urban Design Legacy
Adhere to the design principles of the L'Enfant and McMillan Plans in any improvements or alterations to the city street plan. Where the character of the historic plan has been damaged by intrusions and disruptions, promote restoration of the plan through coordinated redevelopment and improvement of the transportation network and public space. 1010.7
Action HP-2.3.A: Review of Alterations to the Historic City Plan
Ensure early consultation with the Historic Preservation Review Board and other preservation officials whenever master plans or proposed redevelopment projects envision alterations to the features of the historic city plan. 1010.8
Action HP-2.3.B: Review of Public Improvements
Ensure an appropriate level of consultation with the State Historic Preservation Officer before undertaking the design and construction of public space improvements in the L'Enfant Plan area and the public parks of the McMillan Plan. 1010.9
