Denver’s rooftops are going green: What does it mean?

Leila and Ken

Fifty-four percent of Denver voters passed the green roof initiative in November 2017, requiring rooftop gardens for new buildings with at least 25,000 square feet of gross floor area, and for roof replacement on existing buildings. What does that mean for Denver and how can we expect the cityscape to change over the next years? CU on the Air host and University of Colorado V.P. of Communications Ken McConnellogue chats about the future of green roofs with Leila Tolderlund, assistant professor of landscape architecture and urbanism at CU Denver.
