Reimagining College Walk: A Thoughtful Approach to Landscape Renewal

Columbia’s College Walk is one of the most iconic and cherished spaces on the Morningside campus – home to marriage proposals, the annual tree lighting, and countless student memories. It’s also the most heavily traveled path on campus, serving as a central artery for daily life at Columbia. These two defining qualities – its symbolic significance and high foot traffic – recently converged in a comprehensive plan to reimagine the landscaping of College Walk in response to necessary changes.
 
As part of its ongoing stewardship, Columbia’s Grounds team regularly surveys and conducts scientific assessments of campus trees in collaboration with professional arborists. Evaluations revealed that several little-leaved linden trees along College Walk were in declining health. Issues such as trunk decay, lack of anchoring structural roots, and other irreversible conditions posed potential safety risks if left unaddressed, prompting the professional arborists to recommend their removal.

While the removal of these trees was necessary, it also presented an opportunity to rethink the landscape design of College Walk. Guided by best practices in arboriculture and a commitment to preserving the beauty of the space, the Grounds team – again in consultation with arborists – developed a plan that honors the past while looking to the future.

At the heart of this plan is the decision to highlight Kwanzan flowering cherry trees, which have graced College Walk for decades. These trees will now take center stage, while simultaneously opening sightlines to showcase the grandeur of McKim, Mead, and White buildings and their recently restored windows along College Walk’s perimeter. Cherry trees are the most prevalent tree type on the Morningside campus, and their vibrant spring blossoms are the surest sign that spring has arrived each year.
 
Linden trees will remain prominently featured at the ends of each tree plot near the Broadway and Amsterdam gates. This arrangement not only supports the health of the cherry trees – whose growth was previously stunted by the lindens – but also reflects the arborists’ findings: the lindens had struggled due to limited space available for trees of that size to grow, which compromised their root systems and threatened their vitality. 

“As stewards of Columbia’s historic Morningside campus, our team is entrusted with making thoughtful, long-term decisions that ensure the health and beauty of our landscape,” said Executive Vice President for University Facilities and Operations David Greenberg. “This plan for College Walk reflects our expertise in arboriculture and deep respect for the campus’s legacy.”
 
Enhancements to College Walk will also include seasonal plantings in the tree plots and the addition of new benches along the perimeter, expanding casual gathering spots across campus that continue to grow in popularity.
 
Removal of the remaining diseased trees, installation of perimeter benches and planting of seasonal flora will take place this summer. All updates are scheduled for completion in time to welcome the Columbia community back for the fall semester.
