Looks like the National Capital Planning Commission likes Ike.

The commission gave its final approval for the Dwight D. Eisenhower Memorial, meaning the $150 million project can begin construction at a 4 acre site on the National Mall between the National Air and Space Museum and the Lyndon B. Johnson Building.

It’s taken nearly two decades to get to this stage in the game. Eisenhower’s descendants clashed with architect Frank Gehry over the memorial’s design from the get-go. Ultimately, Rocco Siciliano, who chaired the memorial commission, said in 2013 that “the family deserves to be heard but they do not deserve to be obeyed.”

Still, despite the National Capital Planning Commission giving final design approval in 2015, the memorial commission continued to make tweaks, necessitating this new vote on Thursday evening.

The family ultimately gave its blessing for the final design in September.

The memorial will feature Eisenhower Square, an urban park with a memorial in the center, and bronze statues of Eisenhower at various phases of his life sprinkled throughout, alongside some of his famous quotes.

There will also be a large transparent tapestry made of stainless steel cables, which was revised in this final design to preserve vistas to the nearby Johnson Building, where the Department of Education resides. While the tapestry once depicted Eisenhower’s Kansas hometown, it’ll now represent peace time in Normandy, France, representing his time as a military general in World War II.

This spring, the General Services Administration awarded Bethesda-based Clark Construction with the job of readying the site.

The project also scored $45 million in funding from Congress in its last omnibus budget, and will request $41 million more this year.

The Eisenhower Memorial Commission is also trying to raise about $25 million in private funding. Its website indicates it has already received between $1 million and $4.99 million from Taiwan, as well as corporations like FedEx, Honeywell, and Pfizer.

The memorial commission has scheduled a ceremonial groundbreaking on the site for November 2 at 10 a.m.
