Quick Summary

The National Park Service has presented a memorandum of agreement to historic preservation groups outlining measures to reduce the impact of President Donald Trump's planned 250-foot triumphal arch in Washington, D.C., following an assessment that it would have adverse effects on nearby historic sites. Federal officials propose restrictions on construction noise and vibrations, dust control, and historical documentation as part of their plan to mitigate these effects while maintaining pedestrian access during the project. The proposed location for the arch, Memorial Circle near Arlington National Cemetery, is under scrutiny due to concerns about disrupting the visual integrity of historically significant landmarks in the area.

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.
