National Park Service backs Trump’s arch, despite its impact on Washington’s sightline

The National Park Service has formally backed President Donald Trump’s proposed 250-foot memorial arch near Memorial Bridge in Washington, even while acknowledging that it would significantly alter historic views and relationships among some of the capital’s most important monuments.

The Park Service’s new 133-page report says the arch would disrupt carefully designed sightlines connecting the Lincoln Memorial, Arlington House, Washington Monument, Jefferson Memorial, U.S. Capitol, National Mall and other historic sites. One especially important alignment links the Lincoln Memorial, Memorial Bridge and Arlington House—Robert E. Lee’s former home—a design originally intended to symbolize reconciliation between North and South.

Despite those impacts, the Park Service concluded that Memorial Circle remains the appropriate location. Its reasoning is essentially that the very historical importance that makes the site sensitive also makes it the most meaningful location for the monument. Moving the arch elsewhere, the report argues, would undermine the project’s purpose.

The report could strengthen the Trump administration’s position in a lawsuit brought by three veterans and an architectural historian, who argue that such a major alteration of Washington’s monumental landscape should require congressional approval rather than being carried out primarily through executive authority.

Critics point to what they see as a contradiction in the Park Service’s findings: the government acknowledges that the arch would damage historic visual relationships, yet still recommends proceeding with it. Attorney Nicolas Sansone, representing the challengers, says the report actually supports their argument by demonstrating how substantially the project would transform the National Mall area.

The arch has already received preliminary approval from the U.S. Commission of Fine Arts, whose current members were appointed by Trump, as well as initial approval from the National Capital Planning Commission. Further review is expected this fall.

The project is also part of a broader effort by Trump to reshape Washington’s physical landscape, including changes to the Kennedy Center, a large new White House ballroom, renovations to the Lincoln Memorial Reflecting Pool and redevelopment of an East Potomac Park golf course.

The central issue: The Park Service is effectively saying, yes, Trump’s arch will substantially change historically important views in Washington—but it believes that impact is justified because this particular location is essential to the monument’s purpose. That conclusion is likely to become a major issue in the continuing legal fight over whether a president can make such a consequential change to the capital without Congress.
