Architect Frank Gehry is maintaining key elements of his design for a memorial honoring President Dwight D. Eisenhower in Washington, despite criticism from a federal arts panel and outside groups.

Gehry’s Los Angeles-based team presented revisions Thursday to the U.S. Commission of Fine Arts. But the changes were limited to the landscape, adding 74 trees to the planned memorial park.

Gehry has designed a park framed by large metal tapestries depicting the Kansas landscape of Eisenhower’s boyhood home. Statues of Ike as president and World War II general would stand at the center.

In November, several members of the arts commission objected to the design’s towering columns and side tapestries. But Gehry made no changes in response.

Commissioners generally favored the landscape design Thursday and didn’t comment on Gehry’s tapestries.
