Arlington County is taking Donald Trump’s proposed triumphal arch to court, opening a new front in the fight over his plans to remake Washington in his own image. The Virginia county’s board filed its lawsuit against the Trump administration on Thursday.

The complaint, filed in the Eastern District of Virginia, seeks to block construction of the massive arch in Washington, D.C. It specifically names Secretary of the Interior Doug Burgum and acting director of the National Park Service Jessica Bowron.

The legal challenge arrives shortly before a final vote by the National Capital Planning Commission. That vote is scheduled for Nov. 5, two days after the midterm elections.

“The Trump-Vance Administration has made it a priority to remake the physical landscape of the Nation’s Capital in President Trump’s image and based on his whims, destroying treasured public spaces in the process,” attorneys for Arlington County wrote in the complaint.

County lawyers argue that the arch would bring serious consequences for Arlington, its residences and tourists. Arlington County is home to both the Pentagon and the historic Arlington National Cemetery.

The complaint raises particular concerns about flights traveling into and out of Reagan National Airport. Lawyers say the arch could force certain flights to be diverted, increasing both noise and air pollution in Arlington.

“It threatens to increase noise and air pollution in Arlington by necessitating the diversion of certain flights into and out of Reagan National Airport,” the lawyers wrote. “Using the Arch to store large stockpiles of ammunition and as a staging point for drones and snipers, so close to commuters and tourists, will dramatically worsen these public-safety harms and the risk of accidents.”

The planned structure would tower more than twice as high as the Lincoln Memorial. It would also stand almost twice as high as the Arc de Triomphe in Paris and exceed height limitations established for safe airplane travel to and from Reagan National Airport.

Arlington County Board Chair Matt de Ferranti said county officials had participated diligently and in good faith in the review process. He said they had repeatedly identified severe and unusual consequences for the county and its residents.

“Despite these concerns and that process not being complete, it was recently, unilaterally, announced that the project will move forward anyway — entirely disregarding protocol and months of work. Enough is enough. We will do all we can to hold this administration accountable and to protect and serve the best interests of our community,” de Ferranti said in a Thursday press release.

The county is not the first group to challenge Trump’s arch. Vietnam veterans filed a lawsuit in February, arguing that the project lacked congressional authorization and would obstruct the line of sight between the Lincoln Memorial and Arlington National Cemetery.

That visual connection was deliberately created to symbolize the country’s reunification after the Civil War, according to the source. The same veterans filed an emergency motion in September seeking a temporary restraining order to stop the administration from beginning excavation for the proposed 250 foot arch.

The arch is one of several vanity projects Trump has proposed while seeking to significantly reshape the Washington skyline during his presidency. The other projects include controversial renovations to the Reflecting Pool and demolition involving the White House East Wing and Rose Garden.

Trump’s plans also include closing and renaming the Kennedy Center. That project has become entangled in a legal battle lasting for months.

Democracy Forward is working with the Arlington County Board on its court challenge. The organization’s President and CEO, Skye Perryman, said the administration cannot discard legal review requirements simply because the president wants the project to proceed quickly.

“The president is not allowed to bypass legal review requirements just because he wants to move quickly on his own whims, and NPS clearly violated the law by failing to conduct an adequate review of the arch project,” Perryman said. “At a time when millions of Americans are struggling to make ends meet, we don’t need vanity projects.”

With the planning commission’s final vote approaching, Arlington County is asking the court to intervene before the project advances further. Its lawsuit adds another formidable source of resistance to an arch already facing legal opposition from veterans and sharp concerns about public safety, aviation and treasured public spaces.
