The U.S. Interior Department is contesting the applicability of Washington, D.C.'s longstanding height limits to federal projects, specifically in the context of the proposed Trump arch. This stance breaks with over a century of precedent governing the city's building regulations. A federal panel currently reviewing the arch project will decide if these height restrictions apply. Experts suggest that if the panel sides with the Interior Department, it could lead to significant changes in the city's architectural landscape.
