Mark Johnson – Salt Guest
Founder of Civitas
Mark Johnson is a landscape architect and urban designer known for leading large-scale park, public space, and urban regeneration projects through Civitas, the Denver-based design firm he co-founded. A graduate of both Utah State and Harvard Universities, his work focuses on transforming brownfield, infrastructural, and underused urban sites into resilient public landscapes that integrate ecology, mobility, land use, and civic life. Johnson’s major projects have included the redevelopment of Stapleton Airport in Denver, the Los Angeles River Revitalization Master Plan, Museum Park Miami, and the San Diego North Embarcadero. His practice is defined by a strategic approach to complex urban conditions, using landscape as a framework for environmental repair, social connection, and long-term city-making. Johnson has also contributed to regeneration projects in North St. Louis, including the former Pruitt-Igoe site, as well as Parcel 1 in Dehsabz New City, Kabul. Outside of his practice, Johnson is a visiting lecturer at various universities.
