Quick Summary

The Trump administration acknowledges that constructing a 250-foot triumphal arch along the Potomac River will have adverse effects on the historic landscape. These impacts, including obstructed views of Arlington National Cemetery, cannot be fully avoided because the location is central to the project's purpose. The National Park Service plans to mitigate these effects through monitoring and improvements such as new walkways and plantings, but a group of Vietnam War veterans has sued to block construction due to its historic significance and lack of congressional authorization.

Story summary

The Trump administration acknowledged that President Donald Trump's proposed 250-foot triumphal arch at Memorial Circle would have unavoidable "adverse effects" on historic sites in Washington D.C. The National Park Service sent a memorandum of agreement (MOA) to various preservation groups, including the National Capital Planning Commission and Virginia Historic Preservation Office, detailing steps that could lessen the project's impact. These measures include monitoring construction vibrations and controlling noise levels while adding new walkways and lighting improvements around the area. However, Rep. Don Beyer warned that placing the arch near Ronald Reagan Washington National Airport could pose additional risks to air traffic safety, given that airplanes fly over the site every 45 to 60 seconds during peak hours. The FAA is still studying potential aviation hazards but initially suggested the installation of obstruction lights might suffice.

Trump has said called the arch a "wonderful addition to the Washington D.C. area," saying in a social media post earlier this year that it will be the "GREATEST and MOST BEAUTIFUL" of structures "anywhere in the world." The arch received initial approval in July from the National Capital Planning Commission, a federal agency led by Trump's hand-picked appointees, despite hours of public testimony against the project.
