Save the Tidal Basin

  • An American Icon

    A part of the National Mall, the Tidal Basin comprises some of our nation's most renowned monuments and famed cherry trees.

  • History at Risk

    Rising sea levels and as much as $500 million in deferred maintenance threaten this 107-acre landscape.

  • Save the Tidal Basin

    Join us in a three-year campaign to ensure the Tidal Basin is preserved for future generations.

As part of “America’s front yard,” the National Mall Tidal Basin is one of our nation’s most iconic, significant, and beloved public cultural landscapes and commemorative spaces. But this treasured landscape is at a pivotal moment, as subsidence, daily flooding, increasing visitation, and crumbling infrastructure threaten its long-term sustainability.

To ensure the National Mall Tidal Basin can meet the demands of a changing modern environment, we need a bold, creative, and integrated approach that respects, enhances, and revitalizes the Tidal Basin. That's why we've teamed up with the Trust for the National Mall to present the Ideas Lab. The Trust for the National Mall is the leading philanthropic partner of the National Park Service, dedicated to restoring, enriching and preserving the National Mall.

Unlike a Design Competition, which typically selects a winner with a conclusive master plan, the Ideas Lab is a platform for the exchange of solutions and approaches between designers, stakeholders, and the public. Results are provocative and innovative, presenting cultural landscape opportunities in a new light, while tackling fundamental challenges in a comprehensive and respectful way.

Visit the Tidal Basin Ideas Lab Exhibition online to explore the histories and challenges of the Tidal Basin, and share feedback on ideas for the evolution of this important part of America’s landscape.
