VIEW FROM E STREET TOWARD ELLIPSE AND MALL
S DEMOCRACY’S FRONT PORCH S The White House and President Park South’s landscape has transformed over the years as programmatic use, aesthetics and security has changed. E Street, a S SECURITY relatively new passageway, appearing as late as 1967, transformed the simple formal relationship between the White House Garden edge and the Ellipse. Before POINTS its implementation the framework from the McMillan Plan of 1901 created the basis of President Park South’s formal order and before it, AJ Downing’s 1851 plan established the Ellipse and side panel landscape. There have been other alterations and additions, but these three formal manifestations are responsible for what we experience today. The new design for E street NW and Presidents Park South is a palimpsest of the various voices and ideas of past epochs that shaped this distinct and important landscape offering new ways for the public and administration to functionally coexist in a landscape that pays homage to its rich history and tradition while empowering both to participate in the rich dialogue of democracy. FIRST DIVISION SHERMAN PARK The conceptual approach to the E street design and Presidents Park South builds on ideas of hybridity; how to create effective security for the White House and MONUMENT grounds while creating a dynamic landscape for the people of America. How can landscape space balance both, through the integration of formal concepts and FOUNTAIN site architecture? One of the characteristics that mark a great society is its ability to embrace its past while moving forward. The landscape can bear testament through the juxtaposition of the new and old. The new design emanates from the sampling of AJ Downing’s formal circuitry of pathways. The lacy and meandering S formal structures are rotated overlapped and scaled to fi t within the White House and Mall context. E Street and adjacent pedestrian paths are enmeshed in the S larger scale movement and fl ow of the Capital plan, creating a continuous fi eld of experience. A 3-foot high, 800-foot long Ha-Ha wall that forms an edge between the northern edges has the Ellipse and E Street. The wall is multiplitious in its form and function. Firstly it serves as a secondary barrier for security, operating as a secure boundary East/West connecting back to the security post at 15th and 17th street. Secondly, it provides a visual foil along the north south axis. From the S Truman Balcony, the President and First Family are able to look out over the Ellipse unfettered by the visual presence of the road/path south of the wall. From the S south looking North the wall visually diminishes the space between the wall and White House fence, bringing the White House visually closer to viewers at the distant Ellipse. And thirdly, the wall serves as a great public space. On its north side, it undulates with the sampled pathway and circuitry, providing both seating and viewing opportunities. The concave and convex geometry along the wall create a dynamic set of experiences and functions, resolving the geometry of the two BUTT-MILLET FOUNTAIN LILY TRIANGLE opposing curved forms of the Ellipse and White House Garden. FRONT PORCH Americas Front Porch is a place for the practice of our First Amendment Rights, a place for visitors to view the ellipse, White House and its garden landscape in an open, aesthetically pleasing environment. The new landscape is composed of two materials that metaphorically speak to this epoch, stone and glass. Stone is the material of Washington DC, and in particular suggest the timeless nature of our government and contemporarily relates to safety and protection. Glass on the other hand suggests optimism; care, fragility and wonder…the two together are emblematic of this time period.

Ha-Ha Wall will serve as a security barrier, achieving the Department of State K12 certifi cation either through further development of a concrete and steel foundation within the wall (as shown in section) or through integrating a K12 rated bollard system within the wall’s core. Overall, our team will work with the client to further develop wall sections that meet both the appropriate levels of impact resistance and the high atheistic standards. (E) SECURITY BOLLARD
