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.
