The ROAR Podcast: Steve Lefton

Steve Lefton has spent twenty-nine years at what he jokingly calls "the largest firm you've never heard of." Kimley-Horn is eleven thousand people across a hundred and sixty offices — engineers, planners, landscape architects and environmental scientists who handle nearly everything on a project except the architecture. As Executive Chair, and previously as president and CEO during a stretch in which the firm doubled in size, Lefton has watched sports venues transform from standalone buildings into full districts that have to work three hundred and sixty-five days a year.

He joins Caroline to trace that shift from the ground up. The conversation moves from his early redevelopment work in post-Hurricane Andrew Miami, to why the districts that succeed feel like organic neighborhoods rather than projects, to the scale problem hiding in plain sight: a New York City block runs about three acres, and these developments can span sixteen to a hundred blocks. That math, he argues, makes public partnership unavoidable.

Along the way: what a Kimley-Horn employee is doing beside a police officer on game day with an earpiece in, how the firm moved 2.8 million fans during the World Cup, where Lefton draws the line on AI in a profession of licensed professionals, and why a Commanders project on the RFK site is personal.
