Jefferson Memorial Seawall
Jefferson Memorial Seawall
The Trust helped leverage more than $150 million in federal dollars for restoration projects on the National Mall, including repairing the sinking plaza in front of the Jefferson Memorial. Prior to the work that was completed on the plaza, the Jefferson Memorial and its sea wall were sinking eight inches per year. Engineers working on the project discovered that the timber pilings originally constructed in the 1930’s to support the sea wall were slipping away from the memorial.

The oldest structure on the National Mall and untouched for more than 40 years, the Lockkeeper’s House was moved away from the busy corner at 17th and Constitution and fully restored.
