Collaboration in Design: JBC’s Role in WashU’s East End Transformation

JBC played a key technical role in the East End Transformation of Washington University’s Danforth Campus, resulting in an ambitious redevelopment that replaced six acres of surface parking with a vibrant, pedestrian-friendly landscape. This transformative project introduced five new campus buildings, a below-grade parking garage, and a thoughtfully designed public realm that now welcomes visitors with green space, gathering areas, circulation paths, and a sense of arrival onto campus.

JBC collaborated closely with Michael Vergason Landscape Architects, Arbolope Studio, and KieranTimberlake to design and coordinate site-wide irrigation, landscape subdrainage, and engineered soil systems. The complexity of the project required precision as irrigation and soils transitioned across five new buildings and over an underground garage, where soil weights and structural profiles had to be carefully managed. The JBC team successfully navigated a broad spectrum of soil conditions, supply-related material changes, integration with existing irrigation systems, and turf fire lanes, all while preserving the integrity of the landscape design.

The result is a lush and inviting landscape that has redefined the eastern edge of the WashU campus. With strong early performance from the plantings, including rapid growth of smaller-caliper trees, this new campus entry is already thriving. “The transformation at the East End is a project I always look forward to visiting,” said Spencer Sneller, Senior Project Manager at JBC. “WashU is a beautiful campus, and MVLA’s planting design continues to evolve and mature.”

Revitalizing City Ridge in Washington, D.C.: JBC's Expertise in Green Infrastructure at Work

Located in Washington, D.C., City Ridge reimagines the historic Fannie Mae headquarters, transforming it into a dynamic, mixed-use development. With a thoughtful blend of preserved architecture and modern design, the development spans more than nine acres of vibrant green roofs, terraces, and public spaces, all integrated above a network of underground parking and complex infrastructure.

JBC played a key role in bringing City Ridge's landscape vision to life. Our team provided comprehensive site-wide design services for irrigation, soils, and drainage, supporting everything from structural soils beneath paved surfaces to the complex needs of elevated green roof environments.

The scope was as diverse as the site itself. We managed soil specifications across multiple types of soils, including structural, planting, turf, green roof, and bioretention, along with custom blends for street trees and heritage plantings. Working in close collaboration with Michael Vergason Landscape Architects, ParkerRodriguez, and Shalom Baranes Associates, as well as structural, civil, and MEP engineers, we ensured every design detail was aligned to support both aesthetics and long-term plant health.

Coordinating across nine distinct buildings with varying site conditions, JBC approached the challenge of irrigation layout, stub-out locations, and conduit routing with precision.

Across the project, our integrated approach resulted in a resilient and cohesive landscape system that not only meets rigorous performance standards but also enhances the design and overall experience of this urban space.
