The National Capital Planning Commission on Thursday approved architect Frank Gehry’s plans for a memorial park to be built on a four-acre site along Independence Avenue between the National Air and Space Museum and the Education Department building. In June, the United States Commission of Fine Arts gave its critical, final approval.

Members of the panel — one of two government agencies that must approve the memorial plan before construction can begin — described the edited version of Gehry’s design as a “stronger project” and a “substantial improvement” over the previous scheme, which the CFA had previously accepted.
