The Citadel on Colfax is a 29.1-acre mixed-use infill development in Aurora, Colorado, just east of the Fitzsimons Veteran’s Administration Hospital.

Galloway has been working with the master developer to create a unique and flexible development that can support a variety of uses, including retail, medical, office, supportive housing, and single-family residential.

The landscape architecture design is a key element to the organization of the site, which provides a meandering trail and associated park spaces that weave together the various uses of the development. Galloway worked with the master developer and the City of Aurora to develop the site’s open space plan. It offers recreational amenities, a central community gathering space, ‘Central Park,’ and smaller pocket parks for the residents of this new neighborhood on Colfax.

The Granby Ditch is an unimproved historic overflow from the Highline Canal, which was transformed into a major drainageway as Aurora developed around it. The Granby ditch was realigned through the site to accommodate the development and improve the ditch to a stable, defined drainageway. Although part of the larger private project, the Granby Ditch facility is owned and maintained by the City of Aurora and is eligible for Mile High Flood District maintenance. The City of Aurora was integral in the scope and design of this realignment. The project also installed storm sewer inlets and pipes within the roadways.

In addition to providing design services for the entire Citadel site, Galloway is also providing services for individual pad sites within the Citadel development, such as the Citadel townhomes, the storage facility, the Dutch Bros, and the Murphy gas station.
